Clinical Presentation and Percutaneous Treatment of Hemolytic Anemia Associated With Paravalvular Leak After TAVR.
JACC Case Rep

Paravalvular leak (PVL) following transcatheter aortic valve replacement (TAVR) is an established complication, albeit rarely associated with hemolytic anemia. This report details 3 cases of significant hemolytic anemia attributed to TAVR-induced PVL, each with distinct clinical presentations and manifestations. These cases underscore the diverse and occasionally subtle clinical presentation of aortic PVL-associated hemolytic anemia.

Background: Transcatheter closure of percutaneous paravalvular leak (PVL) is a technically challenging procedure, especially after surgical mechanical valve replacements (SMVR), as the risk of interference with the prosthetic valve discs and the complex interventional techniques required for mitral PVL closure. Our study was designed to review the results with transcatheter closure of PVL after SMVR.
Methods: From January 2018 through December 2023, a total of 64 patients with PVL after SMVR underwent transcatheter closure with the help of preoperative 3-dimensional printing model and simulator for image evaluation.
Percutaneous Mitral Valve-in-Ring Procedure in a Case of Severe Mitral Regurgitation Repaired with a Surgical Flexible Ring: A Step-by-Step Description.

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.

Background: Mitral annular calcification (MAC) is characterized by severe calcification of mitral annulus and might be associated with both mitral regurgitation and stenosis. It is technically challenging for both surgical and percutaneous approach and is burdened by high mortality.
Case Summary: The present case report describes a complex case of mitral steno-insufficiency (baseline transvalvular gradient = 5 mmHg, effective regurgitant orifice area 0.
Unusual location of aortic root abscess as a complication of bicuspid aortic valve infective endocarditis by a rare organism.
BMJ Case Rep

Cardiology, Aga Khan University, Hospital, Karachi, Pakistan.
A man in his 50s with diabetes, hypertension and history of multiple percutaneous coronary interventions presented with 3 weeks of fever and worsening shortness of breath. There was clinical suspicion of infective endocarditis with raised infective parameters. Transthoracic echocardiogram showed abnormally thickened, bicuspid aortic valve with suspicion of paravalvular aortic root abscess.
