Spontaneous hemopericardium leading to cardiac tamponade in a patient with essential thrombocythemia.

Acute cardiac tamponade requires urgent diagnosis and treatment. Spontaneous hemopericardium leading to cardiac tamponade as an initial manifestation of essential thrombocythemia (ET) has never been reported in the literature. We report a case of a 72-year-old Caucasian female who presented with spontaneous hemopericardium and tamponade requiring emergent pericardiocentesis.

A patient selection score for cardiac resynchronization therapy.

Background: We hypothesized a patient selection score (PSS) may improve patient selection for cardiac resynchronization therapy (CRT).

Methods: Of 136 patients who received CRT, group A included 100 study patients and group B 36 patients for validation. A positive response to CRT was a left ventricular (LV) end-systolic volume decrease of ≥15% and survival from heart failure at end of follow-up.
