This case report highlights the rare echocardiographic finding of left ventricular diastolic collapse in a patient with low pressure cardiac tamponade.
LV collapse on echo may signal low-pressure tamponade despite normal pressures; this Level 5 case leaves diagnostic criteria unresolved.
A case of systemic hypotension with volume depletion not responding to intravenous fluids was found to have features of cardiac tamponade on two-dimensional (2-D) echocardiography. Intracardiac pressures were normal on cardiac catheterization. An interesting observation was the presence of left ventricular (LV) collapse on 2-D echocardiography. To the authors' best knowledge, such a case of low pressure cardiac tamponade with LV collapse has not been reported earlier.
