Multiple coronary artery fistulae communicating through a sinusoid and emptying into the left ventricle.

This case report describes the occurrence of multiple coronary artery fistulae emptying into the left ventricle and includes a small communication into the left atrium. The initial diagnosis of a coronary artery fistula was made by standard and nonstandard transthoracic two-dimensional echocardiogram and Doppler interrogation. Later, multiple coronary fistulae communicating through a sinusoid and draining into the left-sided chambers were confirmed by angiography.

Predictors of troponin elevation after percutaneous coronary intervention.

The predictors of troponin release after percutaneous coronary intervention were prospectively assessed in 405 consecutive patients. Troponin release occurred frequently (27%) and was associated with complications during the procedure, including sapheneous vein graft interventions, multistent use, glycoprotein IIb/IIIa use, and a history of hypercholesterolemia.

Quantitative assessment of pericardial effusion volume by two-dimensional echocardiography.

The clinical applicability of a method for quantifying pericardial effusion (PE) was studied. The pericardial and cardiac volumes were determined from border tracings of 2-dimensional echocardiograms fitted with 3-dimensional disk models. The PE volume was the difference between pericardial and cardiac volumes.
