Acute mitral regurgitation and cardiogenic shock: Reverse takotsubo cardiomyopathy or acute coronary syndrome?

ABSTRACT: Reverse takotsubo cardiomyopathy (rTCM) is characterized by basal ballooning and accounts for approximately 1% of all TCM. To our knowledge, there have been no reports describing rTCM complicated by acute, severe, transient mitral regurgitation (MR). A 75-year-old woman with a medical history of hypertension, dyslipidemia, and anxiety presented to the hospital with 2 days of substernal chest pain, dyspnea, and nausea. Initial troponin was 0.203 ng/mL, and electrocardiography showed sinus tachycardia at 121 bpm, with inferior and anterolateral ST segment depressions. Transthoracic echocardiogram (TTE) found an ejection fraction of 30%, apical hyperkinesis, severe hypokinesis of the basal to mid segments of the left ventricle (LV), and a severe central MR jet.
