Treatment of severe mitral stenosis in pregnancy using multi-track mitral balloon dilatation: case report

A case of 31-year old pregnant lady with severe mitral stenosis who benefited tremendously from multi-track balloon valvotomy is presented. She had history of cardiorespiratory arrest during delivery in the previous pregnancy and presented to the obstetrician pregnant again and symptomatic. After detailed cardiac evaluation, she was managed medically up to end of second trimester and then percutaneous balloon mitral valvotomy was done under fluoroscopy with total abdominal and pelvic shielding. The results were dramatic both in terms of haemodynamic changes and in the clinical outcome. The patient went on to give birth to a normal healthy baby. This case illustrates current management approach of mitral stenosis in pregnancy.
