Abstract
We describe a case of tako-tsubo cardiomyopathy in an elderly woman with a permanent pacemaker admitted to the ED with chest pain and dyspnea. Coronary angiography revealed normal coronary arteries. Typical left ventricular apical ballooning was demonstrated on contrast ventriculography. Left and right ventricular ballooning with pulmonary artery systolic hypertension was detected by transthoracic echocardiography. Velocity vector imaging and strain analysis showed a typical pattern of regional myocardial apical right ventricular contraction characterized by paradoxical positive longitudinal systolic strain. Biventricular involvement was associated with hemodynamic instability, signs of pulmonary vascular congestion, and bilateral basal pleural effusion. The patient's clinical condition gradually improved, and she was discharged after prolonged hospitalization. Predischarge echocardiography showed substantial recovery of left and right systolic function along with normalization of pulmonary artery systolic pressure. Right ventricular function should be carefully evaluated in patients with tako-tsubo cardiomyopathy, especially in the acute phase.
