FERNANDEZ VILLAR, Gonzalo et al. Barlow syndrome: A rare etiology of sudden death. Medicina (B. Aires) [online]. 2023, vol.83, n.3, pp.467-470. ISSN 0025-7680.

We present the case of a 60-year-old woman, with a history of mitral valve prolapse, who consulted for dyspnea and palpitations of 2 weeks of evolution up to functional class IV. The admission electrocardio gram showed a moderately responsive atrial fibrilla tion rhythm with frequent ventricular extra systoles. A transthoracic echocardiogram was performed which showed mitral valve prolapse with severe impairment of ventricular function. Barlow syndrome was diagnosed. During hospitalization, the patient presented three epi sodes of cardiorespiratory arrest that were reversed with advanced cardiopulmonary resuscitation maneuvers. During admission, a negative balance was performed, sinus rhythm was reverted and an implantable auto matic defibrillator was placed in secondary prevention. During follow-up, severe deterioration of ventricular function persisted. We highlight Barlow syndrome as a rare cause of sudden death and its association with dilated cardiomyopathy.
