Abstract

Left-ventricular pseudohypertrophy reflecting left-ventricular compression was reported in a selected group of patients with cardiac tamponade. Criteria for the presence of pseudohypertrophy can be established to guide its use as a sign of left-ventricular compression in patients with cardiac tamponade. Left-ventricular wall thickness, diameters, relative diastolic wall thickness (%) = (posterior wall thickness/end diastolic radius) x 100 and estimated left-ventricular mass were measured in patients with small, moderate and large pericardial effusion, in patients with cardiac tamponade before and after pericardiocentesis (16 patients in each group) and in 30 control subjects with normal echocardiograms. Left-ventricular posterior wall thickness was increased (12 +/- 2 vs. 9 +/- 1 mm, p < 0.001), left-ventricular end-diastolic diameter was reduced (3.9 +/- 0.5 vs. 4.6 +/- 0.3 cm, p < 0.001) and relative left-ventricular diastolic wall thickness was increased (61 +/- 13 vs. 41 +/- 4.5%, p < 0.001) only in patients with cardiac tamponade compared to controls, but not in patients with small, moderate and large effusions, respectively (relative wall thickness: 42 +/- 5, 41 +/- 7 and 44 +/- 7%, p = NS). Mean values of the estimated l...Continue Reading
