Isolated left ventricular diastolic collapse in pericardial tamponade: an uncommon echocardiographic finding.

A case of circumferential moderate pericardial effusion causing isolated collapse of left ventricular cavity on two-dimensional echocardiography is reported. Pericardial effusion, mostly of infective etiology, is relatively common in this part of the world. When large enough to cause tamponade, collapse of right atrium, right ventricle, and uncommonly left atrium can be seen.

Optimal fluid amount for haemodynamic benefit in cardiac tamponade.

Objectives: The present study was undertaken to assess the effect of volume expansion on cardiac haemodynamics in patients with cardiac tamponade and to ascertain an optimum amount of fluid that can produce the maximum benefit in tamponade patients.

Background: In patients of tamponade, interim measures may occasionally be needed when facilities for pericardial fluid drainage are not immediately available. Intravascular volume expansion is the most commonly advocated measure but with limited scientific data.

Multimodality imaging of submitral left ventricular aneurysm.

Submitral left ventricular aneurysms are a rare nonischemic aneurysm thought to be developmental in origin. These aneurysms invariably occur at the site of posterior mitral annulus and lead to mitral valve incompetence. We hereby describe a case of a 30-year-old adult with a rare form of submitral left ventricular aneurysm involving whole of the posterior mitral annulus.
