Abstract

Objectives: To assess the immediate results of percutaneous mitral balloon valvotomy (PMBV) in management of severe mitral stenosis. Subjects and Methods: Retrospective cohort study with a data base of 66 patients. We included all the patients proceeding at the Heart Institute of Ho Chi Minh city from January 2015 to May 2021. Results: We reported the results in 66 patients with median age 39.00 (35.00 – 46.00) years old undergoing PMBV. Success with optimal results was achieved in 93.94% patients and severe mitral regurgitation complication occured in 1.52% patients. After PMBV, most patients from NYHA functional class II-III recovered to NYHA class I, mitral valve area (MVA) increased from the median value of 0.86 (0.72 - 1.00) cm²  to 1.70 (1.60 - 1.90) cm², mean mitral gradient decreased from 14.00 (10.75 - 20.25) mmHg to 6.00 (5.00 - 8.00) mmHg, left atrial pressure was from 21.00 (15.00 - 27.00) mmHg to 13.00 (10.00 - 17.50) mmHg, systolic pulmonary pressure decreased from 49.00 (35.00 - 60.00) mmHg to 31.50 (30.00 - 35.00) mmHg and  left atrial diameter also decreased from 45.00 (42.00 - 50.00) mm to 43.00 (39.00 - 46.75) mm. Conclusions: PMBV with Inoue balloon was a feasible, effective and safe procedure for patients with severe mitral valve stenois.
