Ventricular septal perforation naturally reduced in takotsubo cardiomyopathy

      Abstract

      An 80-year-old female was transferred to our hospital with dyspnea. Chest X-ray showed severe pulmonary congestion and electrocardiogram showed ST-segment elevation, abnormal Q, and negative T waves in leads V1–4. Transthoracic echocardiography demonstrated left ventricular apical akinesia with apical ventricular septal perforation. Emergent coronary angiography showed no coronary artery stenosis, and right-heart catheterization revealed a pulmonary to systemic flow ratio (Qp/Qs) of 2.2 on oximetry run. She was diagnosed with takotsubo cardiomyopathy with an associated complication of ventricular septal perforation. Her cardiac function gradually improved with nonsurgical treatment. An oximetry run performed 67 days later revealed that Qp/Qs decreased to 1.2. The size of ventricular septal perforation associated with takotsubo cardiomyopathy reduces naturally by conservative treatment, unlike that in acute myocardial infarction.
