Papillary Muscle Rupture in an Adolescent with No Coronary Lesions.

Papillary Muscle Rupture in an Adolescent with No Coronary Lesions. J Heart Valve Dis. 2017 Mar;26(2):231-233 Authors: Lejko Zupanc T, Logar M Abstract A 21-year-old man with Wolff-Parkinson-White syndrome presented to the authors' hospital with ventricular fibrillation. Coronary angiography failed to demonstrate coronary stenosis, but temporary mechanical circulatory support resolved the ventricular fibrillation and the patient was extubated eight days later. On the next day, however, he had to be re-intubated with symptoms of congestive heart failure. Echocardiography revealed new severe mitral regurgitation and a mobile mass, while emergency surgery revealed a posteromedial papillary muscle rupture (PMR). The mitral regurgitation was repaired with ruptured papillary muscle relocation, artificial chordae implantation, and ring annuloplasty. Postoperative examinations suggested that an arrhythmia-induced coronary circulation hypoperfusion and septic embolization had caused the PMR. PMID: 28820557 [PubMed - in process]
