Determination of sources of error and improvement in accuracy of left ventricular mass measurement by echocardiography.

Abnormal Left ventricular mass (LVM) prognosticates adverse cardiovascular events. Conventionally, LVM measured by echo assumes a prolate ellipsoid (PE) shape; however, it poorly correlates with reference standard of cardiac magnetic resonance imaging (CMR) derived LVM. PE model assumes LVL = 2 × LVID.

Rare Variant of Meigs Syndrome Associated With Pericardial Effusion.

Meigs syndrome is an uncommon entity associated with benign ovarian tumor, pleural effusion, and ascites. Its association with pericardial effusion is extremely rare. We report a case of Meigs syndrome associated with recurrent pericardial effusion that resolved after surgical resection of the ovarian tumor.

Influence of "high" defibrillation thresholds on patient survival and impact of system modification.

Objective: To test whether a high defibrillation threshold (DFT) marks patients with poor outcomes which are improved when DFT is decreased by system modification (subcutaneous coil implant; SM).

Background: The electrical substrate generating fast ventricular arrhythmias may generate poor outcomes among patients treated with implantable cardioverter-defibrillators (ICDs), even when arrhythmias are treated successfully. Since patients with high DFTs have increased mortality, we contrasted survival among patients with high DFT treated with and without SM.
