Dynamic left ventricular outflow tract obstruction in Takotsubo cardiomyopathy resulting in cardiogenic shock

Research output: Contribution to journalArticleAcademicpeer-review

Abstract

We report a case of a 73-year-old female patient, who was admitted to the coronary care unit due to chest pain, malaise and near syncope. During physical examination, the patient was hypotensive and there were signs of left-sided heart failure and a loud systolic murmur. Echocardiogram showed apical ballooning with dynamic left ventricular outflow tract obstruction, based on systolic anterior motion of the mitral valve with important mitral valve regurgitation. In the acute setting, the cardiogenic shock was treated cautiously with fluid resuscitation and intravenous metoprolol, resulting in direct stabilisation of her haemodynamic condition. As a codiagnosis, there was a significant stenosis of left anterior descending artery, which was treated successfully by percutaneous coronary intervention with drug eluting stents. During follow-up, left ventricular function normalised, and the left ventricular outflow tract obstruction, systolic anterior motion of mitral valve and related mitral regurgitation all resolved.
