Novel Mitral Repair for Severe Mitral Regurgitation with Associated Ventricular Tachycardia

Mitral valve prolapse is a common valvular abnormality, and an arrhythmic subtype is associated with life-threatening arrhythmia that can cause cardiac arrest. We present a case of ventricular tachycardia (VT) accompanying severe mitral regurgitation (MR) and an extremely elongated, scarred lateral papillary muscle that was treated with papillary muscle resection and novel mitral valve repair. At two year follow up, the echocardiogram shows no MR, and no arrhythmia is identified during 10-day rhythm monitoring, suggesting that the scarred papillary muscle may have been integral to the patient’s VT as well as the MR.
