Abstract
The long-term outcome of patients (pts) undergoing percutaneous coronary intervention (PCI) of unprotected left main coronary artery (LMCA) is unclear so far. We prospectively investigated the outcome of 102 consecutive patients who underwent stent PCI of unprotected LMCA. Patients were divided according to clinical indication for PCI: stable coronary artery disease (CAD) (N = 60), NSTEMI (N = 18), STEMI (N = 24). Expected in-hospital mortality of coronary artery bypass grafting (CABG) was calculated using the European System for Cardiac Operative Risk Evaluation (EuroSCORE) and compared to the observed survival rate during long-term follow-up (mean 1.8 +/- 1.2 years). The observed 30-day mortality was 1.7% (1/60 pts) in patients with stable CAD, 11% (2/18 pts) in NSTEMI patients, and 13% (3/24 pts) in STEMI patients. The observed mortality was lower than the predicted mortality of CABG as calculated by the logistic EuroSCORE. Using receiver-operator characteristics curves (ROC), EuroSCORE demonstrated a high predictive value for both 30-day mortality as well as 1-year mortality (AUC > 0.8; P < 0.01). Prognostically relevant patient related factors (P < 0.01) included severely reduced left ventricular ejection fraction (HR 3.24), ACS (HR 3.18), STEMI (HR: 3.01), Killip class IV (HR 7.69), occurrence of neoplastic disease (HR 3.97), and elevated CRP (HR 3.86). LMCA-PCI was associated with lower long-term mortality rates compared to the estimated mortality of CABG. This prospective observational study suggests that DES-PCI of unprotected LMCA in "all-comers" can be carried out with reasonable risk.
    • "The European System for Cardiac Operative Risk Evaluation (EuroSCORE), one such tool used for patients undergoing cardiac surgery [1], evaluates the risk of postoperative mortality by integrating several clinical and procedural factors. It has gained wide popularity because of its simplicity, and is used not only for cardiac surgery but also for percutaneous coronary intervention (PCI) [2, 3]. Because it has been suggested that EuroSCORE often overestimates postoperative mortality [4, 5], the EuroSCORE II was created to achieve better calibration than the original [6] . "
    [Show abstract] [Hide abstract] ABSTRACT: We evaluated the usefulness of the combination of European System for Cardiac Operative Risk Evaluation score (EuroSCORE II) and SYNergy between percutaneous intervention with TAXus drug-eluting stents and cardiac surgery (SYNTAX) score in predicting risks associated with early and late outcomes after coronary artery bypass grafting (CABG). Between January 2010 and April 2012, 412 patients underwent isolated CABG at our institution. EuroSCORE II and SYNTAX score were calculated retrospectively, and their ability to predict early and long-term outcomes was evaluated. Patients were divided into four groups according to median EuroSCORE II and SYNTAX score: Group 1, low EuroSCORE II, low SYNTAX (n = 103); Group 2, low EuroSCORE II, high SYNTAX (n = 103); Group 3, high EuroSCORE II, low SYNTAX (n = 99); and Group 4, high EuroSCORE II, high SYNTAX (n = 107). Operative death was not different among the groups; however, Group 4 had the highest major complication rate of the four groups (0 in Group 1, 2.9% in Group 2, 3.0% in Group 3 and 8.4% in Group 4; P = 0.011). Multivariate analyses revealed that both high EuroSCORE II (odds ratio [OR]: 4.154; P = 0.030) and high SYNTAX score (OR: 3.988; P = 0.035) were independent predictors of postoperative major complications and that high EuroSCORE II was an independent predictor of late mortality (OR: 4.673; P = 0.016) but high SYNTAX score was not (OR: 0.808; P = 0.662). Actuarial survival rate at 3 years was the lowest in Group 4 (99.0 ± 1.0% in Group 1, 97.7 ± 1.6% in Group 2, 91.9 ± 2.7% in Group 3 and 90.5 ± 4.7% in Group 4; P = 0.045). The combination of EuroSCORE II and SYNTAX score was useful in predicting early major complications after CABG. In the long term, EuroSCORE II continued to be associated with late mortality, but SYNTAX score did not.

    • "Recently, the EuroSCORE failed to predict the outcome following TAVI in the SOURCE registry [12]. However, it could be shown that the EuroSCORE predicts the long-term survival after complex percutaneous coronary interventions [13, 14], although it was not similarly validated for such procedures. Altogether, no dedicated score system is currently available for the prediction of long-term prognosis after TAVI, and patient selection is rather based on the evaluation of surgical risk for candidate patients.

    [Show abstract] [Hide abstract] ABSTRACT: OBJECTIVES Transcatheter aortic valve implantation (TAVI) was developed as a promising new therapy for inoperable and surgical high-risk patients as an alternative to traditional aortic valve replacement. After a successful procedure, prognosis may mainly be determined by comorbidities. However, no appropriate risk score to predict long-term outcome following TAVI is currently available. The aim of this study was to identify predictors of adverse short- and long-term outcomes.METHODS This is a two-centre registry study including a total of 426 TAVI procedures (274 transfemoral [TF] and 152 transapical [TA]) performed at the University Hospital and CardioVascular Center of Frankfurt (Germany) between 2005 and 2011.RESULTSObserved 30-day mortality was 4.8% among TF and 12.6% among TA patients (hazard ratio [HR] TF vs TA was 0.38; 95% confidence interval [CI] 0.19-0.77). Patients with a higher Society of Thoracic Surgeons (STS) score experienced a 6% elevation in the 30-day mortality per point (HR 1.06; 95% CI 1.03-1.10), whereas the predictive value of the logistic EuroSCORE (HR 1.03; 95% CI 1.01-1.05) and EuroSCORE 2 (HR 1.04; 95% CI 1.01-1.07) was slightly lower. Most interestingly, older age (>80 years) and the access type were predictors of 30-day mortality. However, the only independent predictor of long-term mortality in a 30-day landmark analysis was the STS score (HR 1.05; 95% CI 1.02-1.09).CONCLUSIONS The STS score outperforms the logistic EuroSCORE in predicting adverse outcomes following TAVI. The transapical approach is associated with higher perioperative mortality, but does not exert any influence on long-term prognosis beyond the periprocedural phase.

    [Show abstract] [Hide abstract] ABSTRACT: Permanent pacemaker (PM) requirement is a known complication after transcatheter aortic valve implantation (TAVI). There are, however, no systematic data concerning this complication. To determine the incidence and potential predictors of permanent PM requirement after TAVI based on published literature. We conducted a MEDLINE search to identify potentially relevant literature dealing with PM requirement after TAVI. Data were collected on paper extraction forms by 2 independent investigators. There were 32 relevant published studies comprising data of 5,258 patients without an implanted PM before TAVI. An Edwards-Sapiens® prosthesis (ESP) was implanted in 2,887 patients, whereas 2,371 patients received a CoreValve® prosthesis (CVP). The crude incidence of PM implantation after TAVI was 15%. Six hundred and fourteen of 2,371 (25.8%) CVP patients and 189 of the 2,887 (6.5%) ESP patients had to receive a permanent PM (odds ratio [OR] 4.91, 95% confidence interval [CI] 4.12-5.86, P < 0.001). Presence of right bundle branch block (RBBB) before TAVI was a significant predictor for development of complete atrioventricular (AV) block and subsequent PM need (OR 1.358, 95% CI 1.001-1.841, P = 0.02). More than 90% of all AV-block requiring PM implantation occurred immediately or within 7 days after TAVI. Patients undergoing TAVI with implantation of CVP are at significantly higher risk for development of AV block and subsequent need for permanent PM, particularly if RBBB preexists. Since AV block occurs in >90% within the first week after the procedure, careful monitoring should be performed for at least 7 days after TAVI.
