Giant Left Ventricular Pseudoaneurysm as a Complication After Mitral Valve Replacement Surgery

Abstract

57-year-oldwomanpresentedwith seizure, exertional Ashortness of breath (New York Heart Association Class III) and angina-like chest pain. Her cardiac history revealed successful bioprostheticmitral valve replacement for endocarditis 1 year prior. Chest radiography detected a 9-cm mass overlying the left hilum with an incomplete right border (Fig 1A, arrows). On transthoracic echocardiography, there was a communication from the posterior mitral valve annulus with an apparent left ventricular (LV) pseudoaneurysm (PSA) measuring approximately 51 52 mm (Fig 1B). Visualized valves showed thickening of the mitral valve leaflets with adjacent high-density
