Mechanical Mitral Valve Replacement during the 2nd Trimester of Pregnancy.

We report the case of a 44-year-old pregnant woman who was diagnosed with symptomatic severe mitral stenosis that did not respond to optimal medical therapy and balloon valvuloplasty. After a multidisciplinary team discussion on the timing and risks of interventions and postoperative optimization of peripartum anticoagulation, the patient underwent mechanical mitral valve replacement during the 2nd trimester of pregnancy. The outcome was excellent for the mother and the infant. This case emphasizes the importance of a multidisciplinary approach in managing unusual cases.
