A 43-year-old man with severe mitral annular disjunction and bileaflet mitral valve prolapse who suffered a near-fatal arrhythmia was successfully treated with an ICD and robotic mitral valve repair.
Case Report (n=1)
This case highlights the importance of advanced imaging for diagnosis and risk stratification in patients with mitral annular disjunction presenting with sudden cardiac arrest.
Mitral annular disjunction (MAD) is increasingly recognized as a structural abnormality associated with ventricular arrhythmias and sudden cardiac arrest, particularly in the setting of bileaflet mitral valve prolapse (MVP). A 43‐year‐old man with a history of migraines presented following a witnessed out‐of‐hospital cardiac arrest and was successfully resuscitated with a single AED shock. Transthoracic echocardiography showed mitral regurgitation with bileaflet prolapse and suspected MAD. An implantable cardioverter‐defibrillator was placed for secondary prevention, and the patient was discharged in stable condition with outpatient surgical follow‐up where robotic‐assisted mitral valve repair was successfully performed. Advanced imaging plays a pivotal role in diagnosis and risk stratification when MAD presents as sudden cardiac arrest.
Williams et al. (Thu,) conducted a case report in Mitral annular disjunction and bileaflet mitral valve prolapse with out-of-hospital cardiac arrest (n=1). Implantable cardioverter-defibrillator and robotic-assisted mitral valve repair was evaluated. A 43-year-old man with severe mitral annular disjunction and bileaflet mitral valve prolapse who suffered a near-fatal arrhythmia was successfully treated with an ICD and robotic mitral valve repair.
