Nitric oxide in the management of pulmonary hypertension in the context of cardiac surgery in the adult.

Pulmonary hypertension is a significant problem to take into account in the post-operative management of cardiac patients, especially valvular patients. Inhaled nitric oxide allows more effective control of pulmonary pressure and other hemodynamic parameters, with better post-operative results. We present a clinical case of a patient with mitral stenosis and severe pulmonary hypertension, with post-operative hemodynamic instability, in which we used inhaled nitric oxide for better control of pulmonary pressures and to help ventilator weaning.
