Reverse takotsubo cardiomyopathy: two case reports and review of the literature

Abstract

Introduction Reverse takotsubo cardiomyopathy is a rare variant of classic takotsubo cardiomyopathy that presents within a different patient profile and with its own hemodynamic considerations. Its recognition is important for prognostic, evaluation and treatment considerations. Case presentation Case 1: A 69-year-old Caucasian woman presented with substernal chest pain following a motor vehicle accident. During her evaluation, she was found to have positive results for cardiac enzymes and underwent left heart cardiac catheterization. The results of the catheterization demonstrated no significant coronary stenosis. However, her ventriculogram showed basal and anterior akinesis. Case 2: A 62-year-old Caucasian woman began having substernal chest pain that radiated to her shoulder blades. She was taken to a local area hospital where she was found to have elevated troponins. A left heart catheterization showed an ejection fraction of 35% with hypokinesis of the anterior and posterobasal walls of her heart, with 30% stenosis of her left anterior descending artery but no other significant coronary artery stenosis. Conclusion The cases in this report illustrate a lesser-known variant of takotsubo cardiomyopathy.
