Meta-analysis of phase-specific survival after transcatheter versus surgical aortic valve replacement from randomized control trials.

Objective: Transcatheter aortic valve replacement (TAVR) is an established alternative to surgical aortic valve replacement (SAVR) for severe symptomatic aortic stenosis, although phase-specific survival and cause of death are implicated following these procedures. Herein, we conducted a phase-specific meta-analysis to compare outcomes after TAVR versus SAVR.

Methods: A systematic search of databases was performed from inception through December 2022 to identify randomized controlled trials that compared outcomes of TAVR and SAVR.

Role of CTA Surveillance for Management of Endovascular Repair of Aortic Dissection.

Objectives: The aim of this study was to evaluate the effect of timing for post-interventional CT imaging on the rate of re-intervention and all-cause mortality in patients with endovascular treatment of type B aortic dissections (TBAD).

Material And Methods: Data on 70 patients with endovascular repair of aortic dissection during a three-year period from a single institution retrospectively were collected. Study participants were stratified based on those who had a postoperative CTA in the first 30 days after index intervention (early) vs.

Prolonged Ischemia Times for Heart Transplantation: Impact of the 2018 Allocation Change.

Background: In 2018, the United Network for Organ Sharing implemented a change in heart allocation policy resulting in increased organ ischemia times in early analyses. This study evaluated the effect of ischemia time on 1-year mortality in the context of allocation policy changes implemented in 2006 and 2018.

Methods: The United Network for Organ Sharing registry was used to identify adults undergoing heart transplantation from 2000 to 2020.

Pathophysiology and Pathogenesis of Marfan Syndrome.

Marfan syndrome (MFS) is a systemic connective tissue disorder that is inherited in an autosomal dominant pattern with variable penetrance. While clinically this disease manifests in many different ways, the most life-threatening manifestations are related to cardiovascular complications including mitral valve prolapse, aortic insufficiency, dilatation of the aortic root, and aortic dissection. In the past 30 years, research efforts have not only identified the genetic locus responsible but have begun to elucidate the molecular pathogenesis underlying this disorder, allowing for the development of seemingly rational therapeutic strategies for treating affected individuals.
