Abstract:

We present the case of a 44-year-old woman who suffered an out of hospital cardiorespiratory arrest. After six direct current shocks and 10 min of cardiopulmonary resuscitation she had return of spontaneous circulation and regained consciousness. Transthoracic echocardiography showed normal left ventricular ejection fraction and a mildly dilated left atrium. The mitral valve was thickened with myxomatous degeneration (Barlow’s disease) and moderate regurgitation secondary to bileaflet prolapse. Cardiac catheterization showed no coronary artery disease while left ventriculography revealed a mildly dilated left ventricle with preserved systolic function and highend diastolic pressures. Cardiac MRI revealed an enlarged left ventricle with Mitral Valve (MV) prolapse and moderate to severe Mitral Regurgitation (MR). There were no features suggestive of a specific cardiomyopathy other than her valvular heart disease. The patient had an uneventful hospitalization, received an Implantable Cardioverter Defibrillator (ICD), and eventually had MV repair surgery. In this article we also review the literature regarding similar cases and record important data for the epidemiology of the disease and the important research that has been carried out in the identification of prognostic imaging factors and the genetic background of these patients. We emphasize once again that it is especially important to be able to timely identify patients with mitral regurgitation who are at increased risk of sudden cardiac death so that immediate and effective treatment can be offered.
