Mitral and pulmonary balloon valvotomy in pregnant patients

Two pregnant patients, one each with mitral and pulmonary valvar stenosis, underwent successful balloon valvotomy during their third trimester. Single balloon technique was utilised in both and this resulted in a short procedure and fluoroscopy time (9 minutes in patient with mitral stenosis and 3.5 minutes in pulmonary stenosis). The procedure produced satisfactory hemodynamic and symptomatic benefits in both cases with no complications. The patient remained asymptomatic without medications and delivered healthy full term babies at term. Balloon valvotomy is feasible, effective, and safe during pregnancy and should be considered as an alternative to surgery in symptomatic patients refractory to medical therapy.
