[Mitral valve prolapse associated with severe pulmonary hypertension: a case report].

Severe (110/50 mmHg) pulmonary hypertension (PH) secondary to mitral valve prolapse is rare. We reported herein severe PH secondary to mitral valve prolapse in a 65-year-old female. The patient underwent mitral valve replacement and tricuspid annuloplasty. The pulmonary artery pressure after the operation decreased to 69/20 mmHg. Prostagrandin E1 was effective for residual PH compared with nicardipine hydrochloride.
