Severe Mitral Regurgitation After Pmbv? Comparison Between Inoue and Multi-Track Techniques

Abstract

Objectives: To compare the frequency of severe mitral regurgitation after percutaneous mitral balloon valvuloplasty (PMBV) via Inoue balloon and multi-track balloon technique in our population. Methodology: In this retrospective observational study which was conducted at a tertiary care cardiac center of Karachi, Pakistan between 2015 and 2020 on Hospital registry of PMBV patients. Data were categorized in to two groups, Inoue balloon or multi-track balloon technique. Post procedure echocardiographic and catheterization parameters and in-hospital outcomes and complications, including severe MR, were compared between two groups. Results: Out of 470 PMBV procedures, 286 (60.9%) were performed with multi-track and 184 (39.1%) with Inoue balloon. Improvement in mitral value area was significantly higher with multi-track as compared to Inoue balloon (0.66±0.31 cm2 vs. 0.56±0.29 cm2; p<0.001). Severe MR was not significant, 3.5% (10/286) vs. 4.3% (8/184); p=0.639 for multi-track and Inoue balloon. One patient in Inoue balloon group and two patients in multi-track group required emergency valve surgery. Stroke was observed in two patients of multi-track group and two patients from the same group developed tamponade. No in-hospital mortality was observed. Conclusion: Post-procedure severe MR is a significant and frequent complication. Rate of post procedure severe MR are similar for PMBV via Inoue balloon and multi-track balloon. Both methods are equally effective with equal success rate.

“…Similar results to our study were reached by Farooq et al [34] who documented that; post-procedure severe MR is a significant and frequent complication. Rate of post procedure sever MR are similar for PMBV via Inoue balloon and multi-track balloon.…”

Percutaneous Transmitral Commissurotomy - Clinical and Echocardiographic Follow-up in Severe Mitral Stenosis

“…PTMC should be considered the treatment of choice in patients with severe mitral stenosis and favorable valve anatomy in all age groups. [15][16][17][18][19] It is a valuable treatment in developing countries where the majority of the patients have severe disease at a young age and may require repeat intervention. The surgical risk can be minimized significantly if PTMC is opted for the treatment.…”
