Echocardiography is crucial for early recognition of atypical hemodynamic manifestations of cardiac tamponade, such as isolated left ventricular collapse in patients with right-sided pressure overload.
Atypical LV collapse warrants consideration in tamponade with right overload; case reports leave open prospective validation of such echo signs.
Echocardiography in a 23-year-old woman with chronic rheumatic heart disease revealed severe mitral and tricuspid stenosis, severe tricuspid regurgitation with severe pulmonary hypertension, and mild-to-moderate pericardial effusion that resulted in cardiac tamponade with isolated left ventricular collapse. The left ventricle became the victim as this was the only low pressure chamber. This report emphasizes the role of echocardiography in the diagnosis and early recognition of atypical clinical and hemodynamic manifestations of cardiac tamponade.
