The study of pulmonary hemodynamics after mitral valve repiacement in 30 patients, during the first 18 post-operative hours, did show elevated pulmonary vascular resistance from rhe pre-operative leveis in the majority of them. This rise varied directly,wirh the bypass time and was associated with increased right ventricular work, intrapulmonary shunt and more severe ultrastr4ctural lesions of ...
