BACKGROUND Previous studies have suggested that concomitant mitral regurgitation (MR) is a risk factor for acute transcatheter aortic valve implantation (TAVI) failure, but may improve afterwards. Aim of this study was to assess the prevalence, clinical meaning and modifications of MR in patients undergoing TAVI. METHODS In a retrospective, two-center (Potenza-San Carlo and Roma- San Camillo)...
Access for coronary angiogram and intervention after transcatheter aortic valve implantation (TAVI) is gaining importance with a greater proportion of younger, lower-surgical-risk patients undergoing TAVI. We review current evidence available access TAVI risk factors that hinder such access, provide practical guide to optimising
During the past decades, the only effective treatment option for severe, symptomatic, aortic valve stenosis was surgical aortic valve replacement. More than 10 years ago, Alain Cribier performed the first transcatheter aortic valve implantation (TAVI). Since 2007, CE-mark certified aortic valves are available for TAVI. This new technology rapidly achieved a very high clinical acceptance as a tr...
Transcatheter aortic valve implantation applications in Turkey; the role of the heart team approach.
Severe calcific aortic stenosis (AS) is the most common valvular disease in older population, which affects 2-7% of the population over the age of 65 years. In Turkey, the total population is 72.5 million and 7% of them were over 65 years of age according to official data (TUIK) in 2010. Surgery is still a gold standard approach, but surgical risk rises with age and the mean STS (Society of Tho...
INTRODUCTION Transcatheter aortic valve implantation (TAVI) and minimally invasive aortic valve replacement (minithoracotomy and ministernotomy) have become a valuable alternative to conventional surgical treatment of severe aortic stenosis (AS) in high-risk patients. OBJECTIVES The aim of the study was to evaluate long-term results and complications in patients with symptomatic AS treated wi...
BACKGROUND QT dispersion (QTd) is a predictor of ventricular arrhythmia. Ventricular arrhythmia is an important factor influencing morbidity and mortality in patients with aortic stenosis. Surgical aortic valve replacement reduced the QTd in this patients group. However, the effect of transcatheter aortic valve implantation (TAVI) on QTd in patients with aortic stenosis is unknown. The aim of t...
OBJECTIVES Transcatheter aortic valve implantation (TAVI) has been proposed as a treatment alternative for patients with aortic valve stenosis (AS) at high or prohibitive risk for surgical aortic valve replacement (AVR). We aimed to assess real-world outcomes after treatment according to the decisions of the multidisciplinary heart team. METHODS At a tertiary centre, all high-risk patients re...
BACKGROUND Patients with severe aortic stenosis and reduced left ventricular ejection fraction (LVEF) have a poor prognosis with conservative therapy but a high operative mortality when treated surgically. Recently, transcatheter aortic valve implantation (TAVI) has emerged as an alternative to surgical aortic valve replacement (SAVR) for patients considered at high or prohibitive operative ris...
Background—Patients with severe aortic stenosis and reduced left ventricular ejection fraction (LVEF) have a poor prognosis with conservative therapy but a high operative mortality when treated surgically. Recently, transcatheter aortic valve implantation (TAVI) has emerged as an alternative to surgical aortic valve replacement (SAVR) for patients considered at high or prohibitive operative ris...
AIMS Data regarding the effects of TAVI on LV after are scarce and conflicting results have been reported immediately after aortic valvuloplasty. This study aimed to determine the acute haemodynamic effects of transcatheter aortic valve implantation (TAVI) in left ventricle (LV) diastolic performance, immediately after aortic valvuloplasty and prosthesis deployment. METHODS AND RESULTS Sixty-...
