INTRODUCTION: Transcatheter aortic valve implantation (TAVI) has been demonstrated to be an alternative treatment for severe aortic stenosis in patients considered as high surgical risk. Since its first human implantation by Cribier et al., TAVI has been shown to increase survival rate and quality of life for high surgical risks patients. The objective of this study is to provide an overview of TAVI registries and the reporting clinical outcomes based on the VARC-2 definitions. In addition, the comparability and adherence of VARC-2 reporting within the identified TAVI registries was reviewed...

The purpose of this systematic review and meta-analysis was to assess the 30-days safety (bleeding and vascular events) and efficacy (reduction in major stroke, myocardial infarction and mortality) of single anti-platelet (SAPT) versus dual anti-platelet (DAPT) after transcatheter aortic valve implantation (TAVI). We used a meta-analytic method with Mantel-Haenszel methods to calculate the odds ratio (OR) and 95% confidence interval (CI). Only randomized clinical trials that compared 30-days safety and efficacy based on Valve Academic Research Consortium criteria were included...

Patients with severe symptomatic aortic stenosis have a poor prognosis with medical management alone, and surgical aortic valve replacement can improve symptoms and survival. In recent years, transcatheter aortic valve implantation (TAVI) has been demonstrated to improve survival in inoperable patients and to be an alternative treatment in patients in whom the risk of surgical morbidity or mortality is high or intermediate. A representative expert committee, summoned by the Association of Cardiovascular Interventions of the Polish Cardiac Society (ACVI) and the Polish Society of Cardio-Thoracic Surgeons, devel-oped this Consensus Statement in transcatheter aortic valve implantation...

Transcatheter aortic valve implantation (TAVI) has been widely used for the treatment of aortic stenosis. Most pivotal studies of TAVI included patients with a mean age of over 80 years old. Many young patients may also be considered for TAVI because of severe co-morbidities. We sought to describe a group of patients undergoing TAVI at an age below 70 and to compare them with older patients undergoing the procedure. This study included 1,324 consecutive patients from a 3-center TAVI registry from 2008 to 2014...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is a well-established treatment for patients with severe aortic valve stenosis. This procedure requires pre-operative planning by assessment of aortic dimensions on CT Angiography (CTA). It is well-known that the aortic root dimensions vary over the heart cycle. However, sizing is commonly performed at either mid-systole or end-diastole only, which has resulted in an inadequate understanding of its full dynamic behavior. STUDY GOAL: We studied the variation in annulus measurements during the cardiac cycle and determined if this variation is dependent on the amount of calcification at the annulus...

Lower vagal activity is associated with psychopathology independent of age. Research suggests that alterations of vagal activity precede the development of psychopathology. The present review aimed to quantify sex differences in vagal activity in children and adolescents. Studies reporting on sex differences on measures of vagally-mediated heart rate variability derived from short-term recordings under resting conditions in boys and girls were included. Drawing on data from more than 5,000 children and adolescents, we provide evidence that healthy young girls display lower vagal activity and greater mean heart rate compared to boys, a finding that may have implications for risk associated with the development of internalizing psychopathology and somatic ill-health...
