Procedural complications associated with percutaneous mitral balloon valvotomy: A systematic review

Background: Clinical outcomes after percutaneous balloon valvuloplasty in patients with critical mitral stenosis is challenging and widely discussed. Aim of the study was to analyze the results of balloon mitral valvuloplasty (BMV) using the Inoue technique in patients with critical mitral valve stenosis. Material and Methods: From January 2020 to 2022, balloon mitral valvuloplasty was performed in 31 patients with critical mitral valve stenosis using the Inoue technique. There were 14 men (45.2%), women - 17 (54.8%). The patients were aged from 19 to 59 years, on average 42.4±6.1 years. All patients data were analyzed to evaluate the possible outcomes. Results: In 30 (96.4%) patients, a successful BMV was performed. In 1 (3.2%) patients, PMV failed, including puncture was unsuccessful, and it was not possible to pass a balloon catheter from the LA to the LV through the critically narrowed mitral valve opening. These failures took place at the initial stages of mastering the technique. A lethal outcome was noted in 0 (0.0%) case. In all 30 (96.8%) patients after BMV, positive results were obtained: the area of the mitral orifice increased by an average of 2.5 times, from 0.85±0.17 to 2.16±0.76 cm2 (p< 0.001), the maximum gradient at the level of the mitral valve decreased by 60.5%, on average from 26.9±2.95 to 8.9±0.6 mm Hg. (p<0.0001). The maximum pressure in the LA statistically significantly decreased from 40.29±6.01 mm Hg. Art. up to 21.43±3.83 mm Hg (p<0.05), in LA - from 49.7±10.9 to 29.7±8.2 mm Hg. (p<0.05). According to EchoCG data, regurgitation on the mitral valve after BMV appeared in 6 (24.1%) patients up to I degree, in 1 (3.2%) - up to II, and in 1 (3.2%) - up to III. In 16 (61.5%) of 26 patients with initial mitral insufficiency after BMV, the degree of regurgitation remained at the same level, in 8 (30.7%) the latter increased to II, in 2 (7.7%) - to III degree. Conclusion: BMV using the INOUE technique is a highly effective minimally invasive treatment method, accompanied by a low morbidity and mortality rate.
