Incidental Finding of Traumatic Papillary Muscle Rupture on Intraoperative Transesophageal Echocardiogram following a Motor Vehicle Accident.

• Traumatic papillary muscle rupture is a rare cause of acute MR. • Acute MR is typically a low-velocity jet with a triangle-shaped Doppler spectrum. • Methods of quantification using the continuity equation may not be accurate in acute MR. • A high index of suspicion is required to detect acute papillary muscle rupture. • Consider MR with a hyperdynamic LV, near-systolic LV obliteration, and pulmonary edema.
