Comparison of Right Ventricular Function Between Patients With and Without Pulmonary Hypertension Owing to Left-Sided Heart Disease: Assessment Based on Right Ventricular Pressure-Volume Curves.
Right ventricular (RV) failure with pulmonary hypertension (PH) is frequently encountered in patients with advanced left-sided heart disease (LHD). However, RV energetics in patients with postcapillary PH because of LHD has not been well studied. The authors investigated intraoperative RV energetics in patients with PH due to LHD based on pressure-volume curves with three-dimensional transesophageal echocardiography and pulmonary artery catheterization. ⋯ Although cardiac index was similar, RVSWI and RVMWI were significantly higher and SV/ESV was significantly lower in patients with PH because of LHD, suggesting that patients with postcapillary PH have inefficient RV performance.
