Key result
Mitral valve repair and ICD implantation in an 80-year-old woman with acute mitral regurgitation and ventricular fibrillation resulted in no further ventricular arrhythmias over 16 months of follow-up.
Case Report (n=1)
Mitral valve repair may play a pivotal role in preventing potentially lethal ventricular arrhythmias in patients with acute mitral regurgitation due to chordae tendineae rupture.
Hypothesis-generating for mitral valve repair in acute MR with VF; prospective studies needed before practice change.
In this report, we present the case of a previously healthy 80-year-old woman who was referred to surgery after a cardiac arrest due to ventricular fibrillation successfully resuscitated; the following evaluation revealed acute mitral regurgitation due to chordae tendineae rupture. After mitral valve repair, a single-chamber cardioverter-defibrillator was implanted for secondary prevention of sudden cardiac death. After 16 months of follow-up, the patient is asymptomatic without any further episodes of ventricular arrhythmias reported, underlying the pivotal role of mitral valve repair in the prevention of potentially lethal ventricular arrhythmias.

Bortnik et al. (2009) conducted a case report in Acute mitral regurgitation due to chordae tendineae rupture with ventricular fibrillation (n=1). Mitral valve repair and single-chamber cardioverter-defibrillator implantation was evaluated on Ventricular arrhythmias. Mitral valve repair and ICD implantation in an 80-year-old woman with acute mitral regurgitation and ventricular fibrillation resulted in no further ventricular arrhythmias over 16 months of follow-up.
