{Abstract}: Mitral valve prolapse (MVP) is a relatively common valvular disorder characterized by displacement of one or both mitral valve leaflets into the left atrium (LA) during systole. Mitral annular disjunction (MAD) is an associated abnormality where a portion of the mitral valve annulus attaches superiorly in the left atrial wall. Although MVP is often considered benign, it can rarely lead to serious complications such as ventricular arrhythmias, especially when MAD is present. Herein, we present a case of a 63-year-old male with MVP and MAD who experienced sustained ventricular tachycardia (VT) during cardiac stress testing. This case underscores the importance of recognizing MVP with MAD as a potential substrate for ventricular arrhythmias, notably under heightened physiological or induced periods of stress.
