In congenital heart diseases (CHD) of moderate to great complexity involving the right ventricle (RV), the morphologic RV can be exposed to significant stressors across the lifespan either in a biventricular circulation in a sub-pulmonary or sub-aortic position, or as part of a univentricular circulation. These include pressure and/or volume overload, hypoxia, ischemia, and periprocedural surgical stress leading to remodeling, maladaptation, dilation hypertrophy and dysfunction. This review examines the macroscopic remodeling of the RV in various forms of CHD and explores remodeling trajectories, along with the effects of surgeries and residual lesion repair, in tetralogy of Fallot, Ebstein anomaly, congenitally corrected transposition of the great arteries, transposition of the great arteries with atrial switch surgery, and single ventricle palliated by Fontan.

Severe mitral regurgitation (MR) following surgical repair of the mitral valve poses a significant clinical challenge. Patients who have undergone surgery are typically at high risk for a second operation. This report details the case of a 54-year-old male who underwent aortic valve replacement and mitral valve repair using a 34-ring, 14 years prior.

Objectives: This study aimed to evaluate sex-based differences in outcomes following ruptured abdominal aortic aneurysm (AAA) repair, focusing on mortality, morbidity, and postoperative complications.
Design: Retrospective cohort study SETTING: Multi-institutional data from the Vascular Quality Initiative national database, covering a period from January 2003 to December 2022.
Participants: We included 7,548 patients undergoing open or endovascular repair for ruptured AAA: 5,829 men (77.
Background: The use of mechanical circulatory support devices for high-risk percutaneous coronary intervention (PCI) has increased over the past decade despite limited data of benefit. We sought to examine the association between intravascular microaxial left ventricular assist device (LVAD) versus intra-aortic balloon pump use in patients without cardiogenic shock (CS) undergoing PCI.
Methods And Results: This retrospective study analyzed claims data from a large, insured population who underwent PCI without CS from April 1, 2016 to July 31, 2022.
Platelet Volume Parameters as Predictors of Valvular Thrombosis Risk in Patients with Aortic and Mitral Valve Replacement.

Percutaneous valve implantation or surgical replacement with mechanical or biological valves are standard therapies for severe valvular heart diseases. Prosthetic valve thrombosis, though rare, is a serious complication, particularly with mechanical prostheses. This study aimed to investigate the predictive value of platelet volume parameters, including mean platelet volume (MPV), platelet distribution width (PDW), and platelet-large cell ratio (P-LCR), for valvular thrombosis risk in patients undergoing valve replacement therapy.
