    ABSTRACT: To evaluate the feasibility of ultra-low-dose CT for left atrium and pulmonary veins using new model-based iterative reconstruction (MBIR) algorithm. Two hundred patients scheduled for catheter ablation were randomized into two groups: Group 1 (100 patients, Multidetector row CT (MDCT) with MBIR, no ECG triggering, tube voltage and tube current of 100 kV and 60 mA, respectively) and Group 2 [100 patients, MDCT with adaptive statistical iterative reconstruction algorithm (ASIR), no ECG triggering, and kV and mA tailored on patient BMI]. Image quality, CT attenuation, image noise, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR) of left atrium (LA) and pulmonary veins, and effective dose (ED) were evaluated for each exam and compared between two groups. No significant differences between groups in terms of population characteristics, cardiovascular risk factors, anatomical features, prevalence of persistent atrial fibrillation and image quality score. Statistically significant differences were found between Group 1 and Group 2 in mean attenuation, SNR, and CNR of LA. Significantly, lower values of noise were found in Group 1 versus Group 2. Group 1 showed a significantly lower mean ED in comparison with Group 2 (0.41 ± 0.04 versus 4.17 ± 2.7 mSv). The CT for LA and pulmonary veins imaging using MBIR is feasible and allows examinations with very low-radiation exposure without loss of image quality.

    ABSTRACT: Transcatheter aortic valve implantation (TAVI) has extended the treatment options for severe, symptomatic aortic valve stenosis (AS). Risk factors for AS have been shown to be similar to atherosclerosis. Consequently, coronary artery disease (CAD), peripheral vascular and carotid artery diseases are often found concurrently with diagnostic, procedural and prognostic implications. This study sought to describe comprehensive vascular assessment in terms of prevalence, severity and correlations in TAVI candidates. A total of 323 patients (81 ± 6 years) undergoing TAVI were enrolled. Vascular pathologies were evaluated by invasive coronary angiography, computer-tomography (abdominal aorta, renal, iliac and femoral arteries), echo-color Doppler ultrasound (carotid artery), and transoesophageal echocardiography (thoracic aorta). CAD was found in 173 (54 %) patients, of which 65 (38 %) had 1-vessel, 45 (26 %) 2-vessel and 59 (34 %) 3-vessel disease. Carotid artery disease was present in 33.6 % patients, of which 23.6 % unilateral and 10.0 % bilateral. Iliac, femoral and renal stenosis were found in 29.2 %, 22.0 %, and 4.7 %, respectively. Cardiovascular risk factor and gender correlated with CAD. CAD patients presented more frequently with significant stenosis (luminal narrowing ≥50 %) of at least one other district. Multi-districts significant stenosis stratified patients on long-term survival and the coexistence of 3-districts involvement with CAD negatively impacts on mortality. Multimodality imaging assessment shows that coronary, carotid, and peripheral artery disease are often found concurrently in patients undergoing TAVI. Several risk factors and gender correlate with the presence and severity of CAD and peripheral pathologies. Long-term mortality is increased in patients with a more compromised vascular situation.

    ABSTRACT: Motion artefacts due to high or irregular heart rate (HR) are common limitations of coronary computed tomography (CT) angiography (CCTA). The aim of the study was to evaluate the impact of a new motion-correction (MC) algorithm used in conjunction with low-dose prospective ECG-triggering CCTA on motion artefacts, image quality, and coronary assessability. Among 380 patients undergoing CCTA for suspected CAD, we selected 120 patients with pre-scanning HR >70 bpm or HR variability (HRv) >10 bpm during scanning irrespective of pre-scanning HR or both conditions. In patients with pre-scanning HR <65 or ≥65 bpm, prospective ECG triggering with padding of 80 ms (58 cases) or padding of 200 ms (62 cases) was used, respectively. Mean pre-scanning HR and HRv were 70 ± 7 and 10.9 ± 4 bpm, respectively. Overall, the mean effective dose was 3.4 ± 1.3 mSv, while a lower dose (2.4 ± 0.9 mSv) was measured for padding of 80 ms. In a segment-based analysis, coronary assessability was significantly higher (P < 0.0001) with MC (97%) when compared with standard (STD) reconstruction (81%) due to a significant reduction (P < 0.0001) in severe artefacts (54 vs. 356 cases, respectively). An artefact sub-analysis showed significantly lower number of motion artefacts and artefacts related to chest movement with MC (16 and 4 cases) than with STD reconstruction (286 and 24 cases, P < 0.0001 and P < 0.05, respectively). The number of coronary segments ranked among those of excellent image quality was significantly higher with MC (P < 0.001). The MC algorithm improves CCTA image quality and coronary assessability in patients with high HR and HRv, despite low radiation dose. Published on behalf of the European Society of Cardiology.

    ABSTRACT: Objectives To characterize the treatment of complex bifurcation lesions (BL) with the Tryton Bifurcation Stent (TBS) paired with an everolimus-eluting stent (EES).Background Complex BL are associated with higher procedural complications and poorer long-term outcomes. The TBS is a dedicated side-branch (SB) stent designed to be used in conjunction with a standard drug-eluting stent.Methods Prospectively identified, consecutive patients underwent TBS+EES stenting of BL using a protocol which included TBS postdilation and simultaneous final kissing balloon inflations (FKBI). All lesions were systematically evaluated with coronary angiography and IVUS, obtained at procedure completion and at 9 months, and were assessed by independent core laboratories.ResultsThirty-three BL were treated in 32 patients presenting primarily (87.5%) with stable angina and complex BL with angiographic apparent disease in the main vessel (MV) and SB in 87.9% and 75% by site and core evaluation, respectively. Procedural success was 100% and high postprocedure percent stent expansion (MV 96 [93, 109]%, SB 88 [77, 100]%, carina MV 135 [99, 166]%, carina SB 116 [91, 130]%) was demonstrated by IVUS. At 9-month angiographic follow-up (n = 28 patients), one MV in-segment restenosis and one SB in-stent restenosis were observed. SB in-stent late lumen loss was 0.41 ± 0.27 mm. IVUS assessment revealed the absence of stent recoil; percent carinal neointimal hyperplasia (NIH) was 1.8 [0.0,11.2]% in MV and 15.0 [6.7,23.5]% in SB, with NIH volume obstruction of 2.0 [0.7,4.3]% in MV and 14.2 [7.5,29.6]% in SB.Conclusions Stenting of complex BL with the TBS+EES provides high acute success with sustained clinical, angiographic, and IVUS results at 9 months. These excellent results are likely due to the extent of stent expansion at the carina. © 2014 Wiley Periodicals, Inc.

    ABSTRACT: Bifurcation lesions are frequent among patients with symptomatic coronary disease treated by percutaneous coronary intervention. Current evidence recommends a conservative (provisional) approach when treating the side branch (SB). The TRYTON (Prospective, Single Blind, Randomized Controlled Study to Evaluate the Safety & Effectiveness of the Tryton Side Branch Stent Used With DES in Treatment of de Novo Bifurcation Lesions in the Main Branch & Side Branch in Native Coronaries) bifurcation trial sought to compare treatment of de novo true bifurcation lesions using a dedicated bifurcation stent or SB balloon angioplasty. We randomly assigned patients with true bifurcation lesions to a main vessel stent plus provisional stenting or the bifurcation stent. The primary endpoint (powered for noninferiority) was target vessel failure (TVF) (cardiac death, target vessel myocardial infarction, and target vessel revascularization). The secondary angiographic endpoint (powered for superiority) was in-segment percent diameter stenosis of the SB at 9 months. We randomized 704 patients with bifurcation coronary lesions at 58 centers (30 from Europe and 28 from the United States). At 9 months, TVF was 17.4% in the bifurcation stent group compared with 12.8% in the provisional group (p = 0.11), mainly because of a higher periprocedural myocardial infarction rate (13.6% vs. 10.1%, p = 0.19). The TVF difference of +4.6% (2-sided 95% confidence interval: -1.0 to 10.3; upper limit of the 1-sided 95% confidence interval: 10.3) was not within the pre-specified noninferiority margin of 5.5% (p = 0.42 for noninferiority). The SB in-segment diameter stenosis among the angiographic cohort was lower in the bifurcation stent group compared with the provisional group (31.6% vs. 38.6%, p = 0.002 for superiority), with no difference in binary restenosis rates (diameter stenosis ≥50%) at 9 months follow-up (22.6% vs. 26.8%, p = 0.44). Provisional stenting should remain the preferred strategy for treatment of non-left main true coronary bifurcation lesions.

    ABSTRACT: Computed tomography-adapted Leaman score (CT-LeSc) was developed to quantify coronary CT angiography information about atherosclerotic burden (lesion localization, stenosis degree, and plaque composition). The objective of the study is to evaluate CT-LeSc long-term prognostic value in patients with suspected coronary artery disease (CAD). Single-center prospective registry including 1304 consecutive patients undergoing coronary CT angiography for suspected CAD. High CT-LeSc was defined by upper tertile (score, >5) cutoff. Segment involvement score and segment stenosis score were also evaluated. Hard cardiac events (cardiac death and nonfatal acute coronary syndromes) were considered for analysis. Different Cox regression models were used to identify independent event predictors. Kaplan-Meier event-free survival was evaluated in 4 patient subgroups stratified by obstructive (≥50% stenosis) versus nonobstructive CAD and a high (>5) versus a low (≤5) CT-LeSc. Of 1196 patients included in the final analysis (mean follow-up of 52±22 months), 125 patients experienced 136 hard events (18 cardiac deaths and 118 nonfatal myocardial infarction). All atherosclerotic burden scores were independent predictors of cardiac events (hazard ratios of 3.09 for segment involvement score, 4.42 for segment stenosis score, and 5.39 for CT-LeSc). Cumulative event-free survival was 76.8% with a high CT-LeSc and 96.0% with a low CT-LeSc. Event-free survival in nonobstructive CAD with high CT-LeSc (78.6%) was similar to obstructive CAD with high CT-LeSc (76.5%) but lower than obstructive CAD with low CT-LeSc (80.7%). CT-LeSc is an independent long-term predictor of hard cardiac events. Patients with nonobstructive CAD and high CT-LeSc had hard event-free survival similar to patients with obstructive CAD. © 2014 American Heart Association, Inc.

    ABSTRACT: We assessed whether short-term, pre-procedural, intensive statin treatment may reduce contrast-induced acute kidney injury (CI-AKI) incidence in patients with and without acute coronary syndromes (ACS) undergoing coronary angiography (CA) and percutaneous coronary intervention (PCI). Statins may exert renal-protective effects through their pleiotropic properties. However, there have been conflicting reports on the CI-AKI preventive effect of pre-procedural statin administration. Randomized controlled trials published between January 1st, 2003 and February 28th, 2014 comparing the preventive effects against CI-AKI of pre-procedural statins vs. control (lower statin dose, no statin, or placebo) in patients undergoing CA/PCI were included. Data were combined from 9 clinical trials enrolling 5212 patients (age 65±5years, 63% males). Pooled analysis showed that intensive, short-term statin pre-treatment significantly reduced the risk of CI-AKI as compared to control (relative risk [RR] 0.50; 95% confidence interval [CI] 0.39 to 0.64; P<0.001). Pre-specified subgroup analysis showed that intensive statin pre-treatment significantly reduced CI-AKI risk in patients with ACS (RR 0.37; 95% CI 0.25 to 0.55; P<0.0001), with only a non-significant positive trend in patients without ACS (RR 0.65; 95% CI 0.41 to 1.03; P=0.07). No evidence of publication bias was detected. Short-term, pre-procedural, intensive statin treatment significantly reduced CI-AKI incidence in ACS patients, and may contribute to the overall clinical benefit associated with the early use of these drugs in this clinical setting. Its role in non-ACS patients warrants further investigation. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    ABSTRACT: Proper measurement of the aortic annulus (AoA) is crucial for the success of transcatheter aortic valve implantation (TAVI). Transthoracic echocardiography (TTE) is the first step to assess AoA diameter, but a two-dimensional TTE (2DTTE) measurement is no longer accepted as the sole determinant of prosthetic size. The aims of the study were to evaluate feasibility and accuracy of three-dimensional TTE (3DTTE) estimation of AoA dimensions in comparison with multidetector computer tomography (MDCT).

    ABSTRACT: Currently, one of the most relevant innovations in interventional cardiology is the advent of bioresorbable vascular scaffolds (BVS). Among the BVS developed so far, the AbsorbTM BVS 1.1 (Abbott®) is one of the two devices that achieved the CE mark for the use in clinical practice. A reasonable amount of clinical evidence on AbsorbTM BVS has been built up from a large series of trials, of which some have been completed and others are in the enrollment and/or follow-up phases. However, at present there is paucity of data on the efficacy and safety of AbsorbTM BVS in patients with more complex coronary artery disease, who represent the majority of those undergoing coronary stenting in everyday clinical practice. To fill this gap, several all-comers registries are ongoing, with the aim to assess the efficacy and safety of the scaffold in subgroups with particularly complex coronary lesions. The AbsorbTM BVS 1.1 registries include IT-DISAPPEARS (NCT02004730), an Italian multicenter registry, started in December 2013, and endorsed by the Italian Society of Invasive Cardiology (GISE). This registry will enroll only patients with long lesions and/or multivessel coronary disease, with an expected considerable proportion of included patients having complex disease. Therefore, the implementation of meticulous and appropriate implantation technique is of key importance for the accurate assessment of scaffold performance in a broad spectrum of coronary lesions. With the aim of standardizing the procedure for patients included in the IT-DISAPPEARS registry, the present article reports the technical features of Absorb TM BVS 1.1 implantation.

    ABSTRACT: Background Multidetector computed tomography (MDCT) provides detailed assessment of valve annulus and iliofemoral vessels in transcatheter aortic valve replacement (TAVR) patients. However, data on diagnostic performance of MDCT coronary angiography (MDCT-CA) are scarce. Aim of the study is to assess diagnostic performance of MDCT for coronary artery evaluation before TAVR Methods and Results 325 consecutive patients [234 without previous myocardial revascularization, 49 with previous coronary stenting and 42 with previous coronary artery bypass graft (CABG)] underwent invasive coronary angiography (ICA) and MDCT before TAVR. MDCT-CA was performed using the same data set dedicated to standard MDCT aortic annulus evaluation. MDCT-CA evaluability and diagnostic accuracy in comparison with ICA as gold standard were assessed. The MDCT-CA evaluability of native coronaries was 95.6%. The leading cause of unevaluability was beam-hardening artifact due to coronary calcifications. In a segment-based analysis, MDCT-CA showed sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy for detecting ≥50% stenosis of 91%, 99.2%, 83.4%, 99.6% and 98.8%, respectively. The MDCT-CA evaluability of coronary stents was 82.1%. In a segment-based analysis, MDCT-CA showed sensitivity, specificity, PPV, NPV and accuracy for detecting ≥50% in-stent restenosis (ISR) of 94.1%, 86.7%, 66.7%, 98.1% and 88.3%, respectively. All CABGs were correctly assessed by MDCT-CA. In a patient-based analysis, MDCT-CA showed sensitivity, specificity, PPV, NPV and accuracy of 89.7%, 90.8%, 80.6%, 95.4% and 90.5%, respectively. Conclusions MDCT-CA allows to correctly ruling out the presence of significant native coronary artery stenosis, significant ISR and CABG disease in patients referred for TAVR.

    ABSTRACT: Coronary computed tomography angiography (CCTA) has demonstrated high diagnostic performance for coronary lesions detection. However, coronary artery motion blurring, related to high or variable heart rate (HR) is a common drawback. Recently, a novel intracycle motion-correction (MC) algorithm has been developed. Aim of the present review is to evaluate the published literature regarding the impact of MC algorithm compared with standard reconstruction on diagnostic performance of CCTA and to integrate the published data with our local experience. The 2 single-center published studies showed a significant improvement of image quality and coronary interpretability in per-segment and per-artery analysis with MC reconstruction. In the study of Fuchs, these data were obtained using low radiation dose. The study of Leipsic also showed an improvement of diagnostic accuracy. Our experience is consistent with the literature data, demonstrating better coronary evaluability in high HR patients. The multicenter trial ViCTORY will determine if MC algorithm will allow a routine improvement of CCTA diagnostic performance.

    ABSTRACT: Objectives The goal of this study was to determine the long-term prognostic value of coronary computed tomography angiography (CTA) in a large coronary artery bypass graft (CABG) population. Background Coronary CTA has shown prognostic utility in patients without previous revascularization. However, prognostication with coronary CTA in CABG patients has not been fully assessed. Methods Between March 2005 and April 2009, 887 consecutive CABG patients (mean age 66.8 ± 8.4 years) were considered for the inclusion in the study. Patients were classified by the number of unprotected coronary territories (UCTs) and a summary of native vessel disease and graft patency: the coronary artery protection score (CAPS). A primary endpoint (cardiovascular [CV] death, nonfatal myocardial infarction [MI]) and a secondary combined adverse events endpoint (CV death, MI, unstable angina, and late revascularizations) were recorded. Results Among the 887 evaluated, 166 did not meet the inclusion criteria. The final study population consisted of 721 subjects. Ten patients were excluded for unevaluable coronary CTA images. Of the remaining 711 patients, follow-up (mean 73.5 ± 14 months) was obtained in 698. Three hundred forty-seven events were recorded. By univariable analysis, the strongest coronary CTA predictors of events were UCT 2 and 3 (hazard ratio [HR] for CV death/MI: 7.5 and 10.19, p < 0.0001 and p < 0.0003, respectively) and CAPS 4 (HR for CV death/MI: 24.1, p < 0.0001). A high number of UCTs was also a strong multivariable independent predictor of CV death/MI (HR: 7.78 and 10.18 for UCT 2 and 3, p < 0.0001 and p < 0.0007, respectively). Cumulative survival rates for CV death/MI and composite adverse CV events were 86% and 73% with UCT 0, 84% and 49% with UCT 1, 53% and 3% with UCT 2, and 29% and 0% with UCT 3, respectively. Conclusions Coronary CTA appears to be a promising tool for long-term risk stratification of CABG patients. The UCT score has significant prognostic value to predict CV deaths/MI.

    ABSTRACT: Purpose To describe a case of early superficial femoral artery (SFA) thrombosis after stenting in an aspirin low-responsive patient successfully treated with percutaneous mechanical thrombectomy. Clinical and interventional summary Early SFA stent thrombosis occurred in a 65-year-old man treated with multiple stent implantation for chronic total occlusion of the left SFA. The potential cause for thrombosis was a suboptimal PTA [percutaneous transluminal angioplasty] result characterized by no-flow limiting residual linear dissection left untreated and which was associated with low responsiveness to aspirin. Rapid thrombus removal and flow restoration were obtained with the Angiojet Ultra Thrombectomy System (Medrad, Warrendale, PA, USA). Conclusions Treatment of SFA stent thrombosis should be undertaken with the understanding of the underlying thrombotic causes and the knowledge of the most appropriate therapeutic options. A percutaneous mechanical strategy with the Angiojet Ultra Thrombectomy System may achieve rapid and complete recanalization even in the presence of huge thrombotic burden. <Learning objective: New devices have been available for huge thrombotic burden management in acute clinical peripheral settings. A few clinical experiences have been described and the case we present shows the safety and efficacy of the rheolytic thrombectomy for femoral stent thrombosis management avoiding bleeding and distal embolization risks.

    ABSTRACT: Aims: The safety and performance of the Absorb Bioresorbable Vascular Scaffold (Absorb BVS) system (Abbott Vascular, Santa Clara, CA, USA) has been previously established in 131 patients from cohort A and cohort B of the first-in-man ABSORB trial. Following this trial, ABSORB EXTEND was initiated as a global continued access study (outside of the USA) to expand experience with the Absorb BVS system to different geographies with broader inclusion criteria to include the treatment of longer lesions and multiple vessels. We report in this manuscript the twelve-month clinical outcomes of the first 512 patients in this population. Methods and results: ABSORB EXTEND is a prospective, single-arm, open-label clinical study which will enrol up to 800 patients at up to 100 sites. Included are patients with lesions ≤28 mm in length and reference vessel diameter of 2.0-3.8 mm (as assessed by on-line QCA or IVUS). Treatment of a maximum of two de novo native coronary artery lesions is permitted when each lesion is located in a different epicardial vessel. An independent clinical events committee adjudicates all endpoint-related events. At one year, for the first 512 patients enrolled in the study, the composite endpoints of ischaemia-driven MACE and ischaemia-driven target vessel failure were 4.3% and 4.9%, respectively. The cumulative rate of ARC defined definite and probable scaffold thrombosis for this population was 0.8% at one year. Conclusions: This interim analysis of the ABSORB EXTEND study shows low rates of MACE and scaffold thrombosis. The study is registered on clinicaltrials.gov (unique identifier NCT01023789).

    ABSTRACT: Purpose : To assess the safety and efficacy of carotid artery stenting (CAS) of the left internal carotid artery (LICA) from a right radial/brachial approach in patients with bovine aortic arch. Methods : Among 505 consecutive CAS patients treated at our facility between June 2007 and December 2012, 60 (11.9%) patients (44 men; mean age 73±9 years) with LICA stenosis and bovine arch were treated from a right radial (n=32) or brachial (n=28) approach. Three quarters of the patients had characteristics qualifying them at high surgical risk; 52 were asymptomatic. The types of cerebral protection (a distal filter or proximal MO.MA system), stent, and technique were at the operation's discretion. Results : The radial/brachial approach was successful in 59 (98.3%) of 60 procedures; 1 case was converted to a femoral approach. Proximal protection was used in 15 cases (11 brachial, 4 radial) with severe, soft plaques, although the MO.MA system proved too short in a tall patient having a radial approach and a filter was used. Clinical success with no adverse events was 96.7% owing to 1 retinal embolism and 1 minor stroke. Vascular complications occurred in 2 (3.3%) brachial group patients. No major bleeding was encountered. Over a mean follow-up of 18.7±17.5 months, midterm event-free survival was 93%. No target vessel revascularization was necessary. Conclusion : CAS via a right radial or brachial approach is safe and effective in patients with LICA stenosis and types 1 or 2 bovine arch.

    ABSTRACT: Aims: Bioresorbable scaffolds are increasingly used in patients with coronary artery disease undergoing percutaneous coronary interventions. ABSORB EXTEND is an ongoing study that will recruit 800 patients. This report evaluates acute and late scaffold failure in the first 450 patients enrolled in ABSORB EXTEND who have completed 12 months follow-up. Methods and results: Clinical event data from the first 450 patients enrolled in ABSORB EXTEND have demonstrated low rates of ischaemia-driven MACE (4.2%) and target vessel failure (4.7%) at 12 months. There have been seven cases of device failure in this study: three cases of scaffold dislodgement (0.67%) and four cases of subacute or late scaffold thrombosis (0.89%). All scaffold dislodgements occurred in the left circumflex (LCX), and in two cases dislodgement was observed after reinsertion of the same device. Two cases of subacute scaffold thrombosis and two late scaffold thromboses were observed. Two out of four cases of scaffold thrombosis seemed to be related to either premature discontinuation of dual antiplatelet therapy (DAPT) or resistance to clopidogrel. Conclusions: This is the first report specifically describing the incidence and the potential mechanisms of scaffold dislodgement and scaffold thrombosis as seen in the ABSORB EXTEND trial.
