Abstract:
To evaluate the influence of intra‐balloon pressure on the development of severe mitral regurgitation (≥grade 3 + ), we measured intraballoon pressure during percutaneous transvenous mitral commissurotomy (PTMC) in 62 patients using the Inoue balloon catheter. The peak intraballoon pressure was 2.29 ± 0.55 kg/cm 2 . Severe mitral regurgitation as a result of leaflet tear occurred in 7 patients (11%). Patients were divided into two groups those with (n = 7) and those without (n = 55) severe mitral regurgitation. Intraballoon pressure had been significantly higher in those with vs. those without severe mitral regurgitation (2.76 ± 0.31 kg/cm 2 vs. 2.23 ± 0.55 kg/cm 2 , P 〈 0.01). Multiple logistic regression analysis revealed that the occurrence of severe mitral regurgitation was related to only the peak intraballoon pressure. These data suggest that a high intraballoon pressure is a risk factor for severe mitral regurgitation as a result of leaflet tear.
