Cardiac imaging and functional assessment in pregnancy.

There are multiple imaging modalities available for the assessment of pregnant women with known or suspected cardiac disease. Because of its safety and general availability, echocardiography is the preferred study of choice for the evaluation of ventricular function, valvular heart disease, congenital heart disease, evaluation of the aorta, and the estimation of cardiac hemodynamics in a pregnant patient. Cardiac MRI can be performed, especially for diseases of the aorta and complex congenital heart disease.

Pulmonary hypertension and long-term mortality in aortic and mitral regurgitation.

Background: Outcomes data in patients with aortic regurgitation or mitral regurgitation have been limited to small series with generally <10 years of follow-up. The quantitative impact of pulmonary artery hypertension has not been well described. The purpose of this study was to describe the 15-year mortality of aortic regurgitation and mitral regurgitation.

Perioperative outcome and long-term mortality for heart failure patients undergoing intermediate- and high-risk noncardiac surgery: impact of left ventricular ejection fraction.

The impact of left ventricular ejection fraction (LVEF) on outcome in patients with heart failure (HF) undergoing noncardiac surgery has not been extensively evaluated. In this study, 174 patients (mean age, 75+/-12 years, 47% male, mean LVEF (47%+/-18%) underwent intermediate- or high-risk noncardiac surgery. Patients were stratified by LVEF, and adverse perioperative complications were identified and compared.

Maternal congenital cardiac disease: outcomes of pregnancy in a single tertiary care center.

Objective: To evaluate contemporary perinatal and cardiac outcomes of pregnancies in women with major structural congenital heart disease.

Methods: Obstetric, neonatal, and cardiac outcomes were abstracted retrospectively from medical records of all women with congenital cardiac disease delivering at our institution from 2000-2007 and compared by type of structural defect. Predictors of adverse cardiac or obstetric events were identified.

Correlation of transthoracic echocardiography and right heart catheterization in pregnancy.

Objectives: To correlate estimated pulmonary artery pressures (PAP) by echocardiography with right heart catheterization (RHC) measurements and to correlate estimated left ventricular ejection fraction (EF) by echocardiography with cardiac output (CO) measurements by RHC.

Study Design: All women who had echocardiography at a single institution during a 6-year period and underwent RHC during pregnancy were included. Echocardiography estimates of right ventricular systolic pressure (RVSP) and EF were correlated with measured RHC PAP and CO, respectively.
