Filter by:Despite Transcatheter aortic valve implantation (TAVI) evolution regarding techniques, equipment and experience, the need for permanent pacemaker implantation (PPI) post-TAVI remains an important drawback. The electrophysiology testing to stratify the risk or necessity of PPI post-TAVI is endorsed by the up-to-date guidelines and consensus documents and it is a valuable cut-off based method. Part of the answer is maybe hidden in the easy and applicable testing of the atrioventricular conduction system through rapid atrial pacing (RAP) with a common temporary pacemaker lead. This trial is designed to investigate the role and value of RAP after TAVI as a predictor of the necessity of new PPI.
Aortic stenosis (AS) is the most common valvular heart disease among elderly population, with a increasing prevalence due to population ageing. In developed countries, the prevalence of severe AS among ≥75 years is approximately 3.4%. The onset of symptoms is associated with a poor prognosis. Indeed, mortality increases once symptoms appears. For several decades, surgical aortic valve replacement (SAVR) has been the standard of care for symptomatic AS. Transcatheter aortic valve implantation (TAVI) was introduced as alternative treatment in inoperable patients in 2002. In the last two decades TAVI has led to a paradigm shift in the treatment of severe AS, representing a less invasive alternative to surgery. TAVI has shown to be non-inferior or superior to SAVR in several large-scale randomized clinical trials (RCTs) across the full spectrum of surgical risks. The newly available evidence has led to an expansion of guideline recommendations for TAVI. Furthermore, newer generations of transcatheter heart valve (THV) design, better patient selection, and technical enhancements have driven improvement in safety and reduction of procedural complications over time. This observational study aim to prospectively evaluate the safety and efficacy of the procedure and clinical outcomes in patients undergoing TAVI.
Aortic stenosis is highly prevalent in advancing age. The prognosis of this disease has dramatically changed with the surgical replacement of the aortic valve and the trans catheter aortic valve re-placement (TAVI). The TAVI procedure is also successful in octogenarians and frail patients. However, the evaluation before the TAVI procedure requires a high dosage of iodinated contrast agent with, consequently, an increased risk for thyroid dysfunction. The primary endpoint of this study is to assess, prospectively, the incidence and the predictive factors (underlying thyroid disease, medication, food preservative, topical antiseptics) of hypothyroidism after a TAVI procedure. The secondary endpoint is the influence of the occurrence of hypothyroidism after the TAVI procedure on the geriatric assessment.
The primary objective of this study is to compare, in patients with severe aortic stenosis and concomitant coronary artery disease accepted for transcatheter aortic valve implantation (TAVI) and percutaneous coronary intervention (PCI) by the multidisciplinary Heart Team, the safety and efficacy of angiography-guided complete revascularization performed after (within 1-45 days) with angiography-guided complete revascularization performed before (within 1-45 days) TAVI using the Edwards SAPIEN Transcatheter Heart Valve®.
Evaluate incidence, clinical indications, and feasibility of PCI performed after TAVI.
