“…Building upon developments in materials and procedures, and inspired by breakthrough results of stenting for coronary and endovascular procedures, transcatheter aortic valve implantation (TAVI), also called transcatheter aortic valve replacement (TAVR), was introduced by Alain Cribier almost two decades ago [4][5][6] . The successes of TAVI have been dramatic indeed, as poignantly summarized by the recent US Food and Drug Administration approval of new-generation devices for TAVI even in patients at low surgical risk [7] .…”

Aim: The management of aortic stenosis has seen momentous changes thanks to the introduction of transcatheter aortic valve implantation (TAVI, i.e., transcatheter aortic valve replacement). Indications to TAVI have expanded progressively to intermediate-and low-risk patients, but trends in life expectancy have led to an increase of elderly but fit individuals with aortic stenosis eligible for TAVI. Methods: We reviewed the current evidence base on TAVI in the elderly by conducting an umbrella review (i.e., overview of systematic reviews), based on a formal bibliographic search for systematic reviews on TAVI in elderly patients (≥ 65 years). Key, study, patient, procedural, and outcome data were extracted, and validity formally appraised with the Oxman-Guyatt index. Results: From 71 citations, eight reviews were included (totaling 39 studies and 8579 patients): five systematic reviews, and three meta-analyses. Topics of interest were cognitive function before and after TAVI, predictive role of muscle mass and frailty on post-TAVI outcomes, comparative safety and effectiveness of TAVI, and role of rehabilitation to improve patient outlook after TAVI. Thirty-three additional studies were retrieved by means of snowballing, emphasizing the

“…9 The initial results of TAVR have been very encouraging and have generated a great deal of interest and enthusiasm among physicians taking care of patients with AS. 10 Furthermore, TAVR has resulted in marked improvements in health status and quality of life compared with standard therapy over 1 year of follow-up. 11 Paradoxical low-flow low-gradient AS, despite normal left ventricular (LV) ejection fraction, is a recently described entity that has been shown to be associated with a more advanced stage of the disease and worse prognosis.…”

Calcific aortic stenosis is now understood as a complex valvular degenerative process sharing many risk factors with atherosclerosis. Once patients develop symptomatic calcific aortic stenosis, the only effective treatment is aortic valve replacement. In the past decade, transcatheter aortic valve replacement (TAVR) has been developed as an alternative to surgery to treat severe calcific aortic stenosis. Cardiac imaging plays a pivotal role in the contemporary management of patients with calcific aortic stenosis, and particularly in patients being considered for TAVR, who demand detailed imaging of the aortic valve apparatus. In this review, we highlight the role of cardiac imaging for patient selection, procedural guidance, and evaluation of results of TAVR.

“…Driven by advancing technologies and skills, cardiology and cardiac surgery had been one of the medical fields quick to embrace minimally invasive techniques such as trans-catheter valve therapies in the early 2000s 1,2 . Minimally invasive techniques are generally accompanied by an improved patient satisfaction, a higher return to normality, a lesser requirement for post-rehabilitation services, and a marked reduction of costs 3 .…”

Hatem Alkadhi 2 & nikola cesarovic 1,7 the pig (Sus Scrofa Domestica) is an accepted model for preclinical evaluation of prosthetic heart valves and trans-catheter implantation techniques. Understanding porcine cardiac dimensions through threedimensional computed tomography (ct), increases preclinical study success, leading to higher cost efficiency and to the observance of the obligation to the 3 R principles. Cardiac CT images of twentyfour Swiss large white pigs were segmented; aortic root, mitral valve, pulmonary trunk, tricuspid valve, as well as the aorto-mitral angle and left atrial height were analyzed. Correlation coefficient (r) was calculated in relation to body weight. In Swiss large white pigs, valvular dimensions, length of the pulmonary artery and ascending aorta as well as left atrial height correlate with body weight. Coronary ostia heights and aorto-mitral angle size can be neglected in animal size selection; no changes were found for either of the two parameters with increasing body weight.
