Recurrent bleeding from gastrointestinal angiodysplasias associated with aortic stenosis ceased after aortic valve replacement in two patients. In one patient numerous gastrointestinal angiodysplasias disappeared, as shown by endoscopy, after aortic valve replacement. Valve replacement may be adequate treatment for gastrointestinal bleeding from angiodysplasia associated with aortic stenosis. Elective surgery for angiodysplasias should be postponed until after a trial period to ascertain whether bleeding stops after valve replacement.

A 79-year-old woman, previously treated for congenital pulmonary valve stenosis through surgical and transcatheter procedures, presented with worsening dyspnea. This led to the identification of valve thrombosis in her bioprosthetic pulmonary valve. This report delves into the clinical importance of obstructive valve thrombosis, its diagnostic assessment, and potential therapeutic strategies.

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.

Aneurysms of the interventricular membranous septum are a rare anatomical feature that can be detected incidentally on computed tomography or echocardiography. Such aneurysms can pose challenges in the treatment of patients with aortic valve stenosis. A case series of 2 patients with membranous septal aneurysms treated successfully with current-generation balloon-expandable and self-expanding transcatheter heart valves is presented here.

A 75-year-old patient with a history of mitral and aortic valve replacement surgery 7 years ago, presented with progressive dyspnea. Transesophageal echocardiogram showed a mass suggestive of bioprosthetic mitral valve thrombosis. We present the investigation process using imaging, surgical findings, nuclear medicine, and histopathology that result in the diagnosis of cardiac angiosarcoma.

Objective: To identify the risk factors associated with moderate to severe perivalvular leakage (PVL) after transcatheter aortic valve replacement (TAVR) and to construct a prediction model for this risk.
Methods: A retrospective analysis was conducted on 128 patients with severe aortic stenosis who had received TAVR in The Second Hospital of Hebei Medical University from January 2019 to January 2024. The length of the aortic regurgitation bundle and annular circumference ratio were measured by transesophageal echocardiography immediately after the valve implantation.
