apical ballooning of left ventricle

Introduction

dilation of left ventricular apex

Etiology

• Takotsubo cardiomyopathy
• pheochromocytoma

Pathology

• left ventricular systolic dysfunction

Clinical manifestations

• tachycardia, hypotension, cardiogenic shock may occur

Laboratory

• serum troponin I elevated
• serum NT-proBNP elevated
• plasma metanephrines for pheochromocytoma

Diagnostic procedures

• electrocardiogram may show tachycardia, poor R-wave progression, T-wave inversions, prolonged QTc interval
• echocardiogram shows low LV ejection fraction, apical ballooning

More general terms

• ballooning
