Comparative StudyFactors determining early improvement in mitral regurgitation after aortic valve replacement for aortic valve stenosis: a transthoracic and transesophageal prospective study.
Mitral regurgitation (MR) is frequently associated with aortic stenosis. Previous reports have shown that coexisting mitral insufficiency can potentially regress after aortic valve replacement. ⋯ In our cohort of patients with normal left venticular ejection fraction, the majority of moderate MR, associated with severe aortic stenosis, regresses early after aortic valve replacement. Mitral calcifications and/or left atrial dilation seem to be predictive factors of fixed MR.

Multicenter StudyUtilization of intraoperative transesophageal echocardiography during repair of congenital cardiac defects: a survey of North American centers.
Intraoperative transesophageal echocardiography (TEE) has been increasingly utilized during repair of congenital cardiac defects. ⋯ Utilization of intraoperative TEE during surgery for congenital heart disease is widespread; the results of this survey may be useful to individual institutions as they evaluate their utilization of intraoperative echocardiography.

Systolic, diastolic, and pulse pressures as coronary risk factors in a population with low cholesterol levels: a prospective 10-year evaluation.
Pulse pressure (PP) has recently been found to be predictive of subsequent cardiovascular, particularly coronary, events in some middle-aged and elderly populations. ⋯ Although inferior to the predictive power of SBP, PP was an important determinant of CHD risk in a population of a diverse age span and a better predictor than DBP in men.
