Immediate Results of Percutaneous Mitral Balloon Valvuloplasty in Patients with Mitral Stenosis

Introduction: Mitral stenosis is a prevalent valvular disease in developing countries. Percutaneous mitral balloon valvuloplasty (PMBV) is the gold standard treatment. The main objective of this study was to assess the initial results of PMBV in patients with mitral stenosis during 16 years (2002-2018) in Mashhad, Iran. Materials and Methods: From April 2002 to March 2018, 770 patients underwent PMV in department of cardiology. PMV was performed by the antegrade transseptal method using the Inoue balloon. Results: The obtained success rate was 97%. In this study, the valve area increased from 0.9±1.1 to 1.8±0.2 cm2 (P<0.0001). There was no case of peri-procedural death or cardiac tamponade. Additionally, 0.25% of the patients required mitral valve replacement. Severe mitral regurgitation occurred in 0.9% of the subjects. There was no case of cerebrovascular accident, transient ischemic attack, embolic myocardial infarction, or cardiac perforation. Supraventricular tachycardia occurred in 2.59% of the patients. Conclusion: The PMBV by the Inoue technique is a feasible and easy procedure with a short crossing times and low complications.
