Clinical study of reoperation for acute type A aortic dissection

Frontiers in Cardiovascular Medicine

Objective The initial operation for type A aortic dissection has limitations, and there may be a need for reoperation in cases such as giant pseudoaneurysm formation and reduced blood supply to the distal vessels. In this study, we retrospectively analyzed the recorded data of 62 patients.

Early left atrial venting versus conventional treatment for left ventricular decompression during venoarterial extracorporeal membrane oxygenation support: The EVOLVE?ECMO randomized clinical trial

European Journal of Heart Failure

Patients with significant pulmonary oedema or aortic valve (AV) closure during venoarterial extracorporeal membrane oxygenation (VA-ECMO) were randomized to early left ventricular (LV) unloading or conventional strategy groups (1:1). The primary endpoint was the rate of weaning from VA-ECMO during index admission. vs. 1.7 ± 0.6

Abstract 4147910: 22q11 Deletion Syndrome: A Potenitial Risk Factor For Left Pulmonary Artery Hypoplasia and Need For Intervention in Patients With Congeital Heart Disease

Circulation

Animal studies have shown that mice with TBX1 gene mutations have smaller left pulmonary arteries compared to wild type mice, defined by a reduced left pulmonary artery (LPA) to right pulmonary artery (RPA) ratio. A single study has shown this translates to humans with 22q11 and structurally normal hearts.

Latest Medical News: Partial Heart Transplant of an Infant

Wellnest

Unlike traditional approaches relying on non-viable cadaver grafts, this procedure involved the transplantation of a portion of the heart, specifically containing the aorta and pulmonary valves, sourced from an infant donor upon cardiac death. Finally, the pulmonary root was transplanted, completing the intricate procedure.
