Calcified amorphous tumor attached to the membranous septum: a rare clinical entity.

We report a rare case of a pedunculated calcified amorphous tumor (CAT) of the left ventricle attached by a stalk to the membranous septum in a 74-year-old woman who presented with a cerebrovascular accident. We believe this is the first report of a CAT attached to the membranous septum.

Multilayer Perceptron Neural Network Analysis of Fluoroscopic Working Angle on Transcatheter Aortic Valve Implantation Complications.

Background: We sought to determine whether there is a relationship between the fluoroscopic working angle used to achieve a co-planar view during the deployment of the prosthesis during transcatheter aortic valve implantation (TAVI) and rates of complications, including paravalvular leaks, complete heart block, annular rupture, stroke, valve embolization, discharge to a skilled nursing facility and death within thirty days.

Methods: All patients undergoing TAVI at our institution from 2015 to 2022 were retrospectively analyzed. Images were reviewed to determine the fluoroscopic working angle during deployment, and medical records were used to determine the incidence and type of complication.

Mitral Regurgitation due to Entrapment of Cut Mitral Chordal Apparatus in a Bileaflet Disk Prosthesis.

• TEE is essential for the assessment of MVR dysfunction. • TEE can comprehensively assess paravalvular or central MR. • Understanding the pathophysiology of MR after MVR is essential.

Outcomes of coronary artery bypass surgery using modified del Nido cardioplegia in patients with poor ventricular function.

Background: del Nido cardioplegia (DN) has been shown to be safe in adult patients undergoing isolated coronary artery bypass grafting with normal left ventricular ejection fraction. We sought to determine whether it was also safe in adult patients with diminished left ventricular function.

Methods: All patients with preoperative left ventricular ejection fraction ≤ 40% undergoing isolated coronary artery bypass grafting between 1/1/2019 and 7/10/2022 were retrospectively analyzed.
