69. Does pulmonary hypertension affect outcome after mitral valve surgery

Background Pulmonary hypertension (PH) due to left heart disease (LHD) is the most common form of pulmonary hypertension. We know from previous studies that PH in patients with LHD is associated with poor prognosis. Regarding incidence and prevalence of PH associated with mitral valve disease we have different data depending of study population. The purpose of this study was to evaluate effects of pulmonary hypertension on short and long term survival following mitral valve surgery at KFSHR p  = 0.18). Pulmonary hypertension was present in 115 (51%) patients. Duration of hospitalization stay after valve surgery was almost twofold longer in patients with PH (24 ± 48 vs.13 ± 14 days, p  = 0.02). Patients died within 30 days had a significantly higher PASp (64 ± 30 vs. 48 ± 17 mmHg; p  = 0.003). We found a clear tendency to higher mortality in patients with pulmonary hypertension. Conclusions Pulmonary hypertension clearly affects early and late survival after MV surgery. Better survival and shorter duration of hospital stay in patients without PH supports early admission for MV surgery before occurrence of PH.
