Background Degenerative aortic valve disease accounts for 10–20% of all cardiac surgical procedures. The impact of pre-existing comorbidities on the outcome of patients undergoing surgical aortic valve replacement (SAVR) needs further research. Methods The IMPACT registry is a non-interventional, prospective, open-label, multicenter, international...
Article
Full-text available
Background: The vascular access in transcatheter aortic valve replacement (TAVR) was initially dominated by a surgical approach. Meanwhile, percutaneous closure systems became a well-established alternative. The aim of this study was to compare the clinical outcome between the two approaches. Methods: In this retrospective study, we observed 787...
Article
Background Permanent pacemaker implantation (PPI) may be required after transcatheter aortic valve implantation (TAVI). Evidence on PPI prediction has largely been gathered from high risk patients receiving first generation valve implants. Objectives We undertook a meta-analysis of the existing literature to examine the incidence and predictors of...
Article
Infective endocarditis (IE) represented over the last year a growing medical and surgical concern. The changes in etiology and demographic of the disease, which now includes also a large proportion of iatrogenic conditions, has prompted new studies and updates in the guideline for IE treatment. The increasing use of intravascular and intracardiac d...
Article
Full-text available
Transcatheter aortic valve implantation (TAVI) and sutureless aortic valve replacement (Su-AVR) enabled in the last years many patients at high or prohibitive risk to be treated for their severe symptomatic aortic valve stenosis. As often happens in medicine, new techniques bring not only new hopes, but also new problems. In recent years, alongside...
Article
Background Calcification of native aortic valve is a well known variable causing paravalvular leakage (PVL) following transcatheter aortic valve implantation (TAVI). However, there is currently no evidence to support the fact that patients with high calcium load could be better treated with surgical aortic valve replacement (SAVR). Purpose To asse...
Article
Full-text available
Background: Sutureless and rapid-deployment aortic valve replacement (SURD-AVR) has become a prominent area of research as the medical community evaluate its place amongst other aortic valve interventions. The main advantages of SURD-AVR established to date are the reduced cross-clamp and cardiopulmonary bypass (CPB) times, as well as facilitating...

Objective To assess risk factors for paravalvular leak (PVL) after transcatheter aortic valve implantation (TAVI) in a large single-center cohort, including measurement of aortic valve calcification using a reproducible method. Methods We retrospectively analyzed preoperative contrast-enhanced multidetector computed tomography (MDCT) scans of pati...
Article
Objectives: Despite the fact, that transcatheter valve-in-valve (VinV) implantation is an off- label procedure, it is now well established as an alternative in high-risk patients with failing bioprostheses. Treating a failing mitral bioprosthesis in elderly patients with coexisting severe aortic valve stenosis is even more challenging for the heart...
Article
This study provides early results of re-operations after the prior surgical treatment of acute type A aortic dissection (AAD) and identifies risk factors for mortality. Between May 2003 and January 2014, 117 aortic re-operations after an initial operation for AAD (a mean time from the first procedure was 3.98 years, with a range of 0.1–20.87 years)...
Article
We read with great interest the article by Nagayoshi and colleagues [1] that analyzed their experience in teleconference for referring critical cases needing cardiac surgery. However, we are of opinion that the role of telemedicine in cardiac surgery should not be limited to urgent or critical cases, so as to centers in the same country. Diagnosis...
