Balloon-Expandable Valve Geometry After Transcatheter Aortic Valve Replacement in Low-Risk Patients With Bicuspid Versus Tricuspid Aortic Stenosis.

Background: Prospective bicuspid low-risk transcatheter aortic valve replacement (TAVR) registries' data demonstrated encouraging short-term results. Detailed data on transcatheter heart valve (THV) geometry after deployment using contemporary devices are lacking. This study sought to examine valve geometry after TAVR in patients with bicuspid aortic stenosis (AS).

Randomized Trial of Aspirin Versus Warfarin After Transcatheter Aortic Valve Replacement in Low-Risk Patients.

Background: The optimal antithrombotic regimen after transcatheter aortic valve replacement remains unclear.

Methods: In this randomized open-label study, low-risk patients undergoing transfemoral transcatheter aortic valve replacement at 7 centers in the United States were randomized 1:1 to low-dose aspirin or warfarin plus low-dose aspirin for 30 days. Patients who could not be randomized were enrolled in a separate registry.

Left Ventricular Mechanical Support with the Impella during Extracorporeal Membrane Oxygenation.

Venoarterial extracorporeal membrane oxygenation (ECMO) provides systemic arterial support without directly unloading the left heart, which causes an elevated left ventricular (LV) pressure. The aim of the present study was to investigate the adjunctive application of the Impella device for LV unloading in patients during ECMO. This retrospective cohort study included patients who received Impella support in addition to venoarterial ECMO between April 2012 and December 2015.

Extracorporeal Membrane Oxygenation in Massive Pulmonary Embolism.

Background: Extracorporeal Membrane Oxygenation (ECMO) has been suggested for cardiopulmonary support in patients with massive pulmonary embolism (PE) refractory to other treatment or as bridging to embolectomy. The survival benefit from ECMO in patients with massive PE remains unclear.

Methods: Here, we describe 5 cases in which ECMO was used as cardiopulmonary support following massive near-fatal pulmonary embolism.

Extracorporeal membrane oxygenation in transcatheter aortic valve replacement.

Background Patients undergoing transcatheter aortic valve replacement can experience severe perioperative complications leading to hemodynamic instability and death. Venoarterial extracorporeal membrane oxygenation can be used to provide cardiorespiratory support during this time. Methods From 2012 to 2015, of 247 patients who underwent transcatheter aortic valve replacement, 6 (2.
