ABSTRACT
Introduction:
Percutaneous mitral commissurotomy (PTMC) and mitral valve replacement (MVR) are treatments of choice for severe rheumatic mitral stenosis (MS). Data regarding the long-term outcomes of patients who underwent PTMC and MVR are limited.Methods:
A retrospective cohort study was conducted to evaluate the long-term outcomes of patients with severe rheumatic MS who underwent PTMC or MVR between 2010 to 2020. The primary outcome comprised of all-cause death, stroke or systemic embolism, heart failure hospitalization and re-intervention. Cox regression was used to investigate predictors of the primary outcome.Results:
264 patients were included in analysis, 164 patients (62.1%) in PTMC group and 100 patients in MVR group (37.9%). The majority were females (80.7%) and had atrial fibrillation (68.6%). The mean age was 49.52 (SD 13.03) years old. MVR group had more age and AF, higher Wilkins' score with smaller MVA. Primary outcome occurred significantly higher in PTMC group (37.2% vs 22%, P=0.002), as well as, re-intervention (18.3% vs 0%, P<0.001). However, all-cause mortality, stroke or systemic embolism and heart failure hospitalization were not significantly different. In multivariate Cox regression analysis, PTMC (HR 1.94; 95%CI 1.14, 3.32; P=0.015), older age (HR 1.03; 95%CI 1.01, 1.06; P=0.009) and SPAP > 50 mmHg (HR 2.99; 95%CI 1.01, 8.84; P=0.047) were the only predictors of primary outcome.Conclusion:
Primary outcome occurred in PTMC group more than MVR group which was driven by re-intervention. However, all-cause mortality, stroke or systemic embolism and heart failure hospitalization were not significantly different.
