Pulmonary hypertension is a serious disorder, difficult to treat especially in the severe forms. The treatment consists mainly of calcium channel blockers, anti-coagulation, intravenous epoprostenol, inhaled nitric oxide and recent agents as bosentan and sildenafil. Sildenafil, a phosphodiesterase 5 specific inhibitor, has been largely evaluated in primary pulmonary hypertension, and in some cases of secondary pulmonary hypertension including parenchymal and thromboembolic diseases; it has not yet been evaluated in severe pulmonary hypertension with elevated pre-capillary resistance in operated mitral stenosis. We report the cases of two patients operated from mitral valve replacement for severe mitral stenosis with elevated pre-capillary resistance, where oral sildenafil, introduced empirically immediately after the surgical procedure at the dose of 50 mg/d, permitted a significant decrease in pulmonary pressures and resistances, allowing a rapid withdrawal of nitric oxide and reducing therefore hospitalization time in the intensive care unit. We think that this simple treatment, with or without association to nitric oxide, should be generalized to persistent pulmonary hypertension following cardiac surgery.
