Comparison of Surgical versus Transcatheter Pulmonary Valve Replacement Outcomes in Real-World Clinical Practice

BackgroundPulmonary valve dysfunction commonly necessitates intervention in congenital heart disease patients. While surgical pulmonary valve replacement (SPVR) remains the traditional approach, transcatheter pulmonary valve replacement (TPVR) has emerged as a less invasive alternative. This study aims to compare real-world outcomes between these approaches using large-scale, multi-institutional data. MethodsThis retrospective cohort study utilized the TriNetX Research Network to identify patients undergoing SPVR or TPVR between January 2010 and December 2024. After propensity score matching, 5,322 patients were included in each cohort. Primary outcomes included pulmonary hypertension, all-cause mortality, and major adverse cardiovascular events (MACE). Secondary outcomes comprised cardiogenic shock, permanent pacemaker implantation, mechanical ventilation, acute kidney injury, and endocarditis. Outcomes were assessed at 3 months, 6 months, 1 year, 3 years, and 5 years post-procedure. ResultsAt 5-year follow-up, no significant differences were observed between SPVR and TPVR groups in rates of pulmonary hypertension (HR 0.912, 95% CI 0.773-1.077, p=0.278), all-cause mortality (HR 0.963, 95% CI 0.851-1.089, p=0.545), or pacemaker requirement (HR 0.949, 95% CI 0.850-1.059, p=0.346). However, SPVR was associated with higher risk of mechanical ventilation (HR 1.140; 95% CI: 0.963-1.349, p =1.29), while TPVR showed increased rates of acute kidney injury (HR 0.828, 95% CI 0.704-0.973, p=0.022) and endocarditis (HR 0.787, 95% CI 0.661-0.937, p=0.007). At shorter follow-up intervals, TPVR demonstrated significantly lower rates of cardiogenic shock (3-month: 3.5% vs. 4.5%, p=0.002), MACE (3-month: 16.5% vs. 21.9%, p<0.001), and mechanical ventilation (3-month: 23.4% vs. 30.7%, p<0.001). Multivariate Cox regression identified SPVR as an independent predictor of cardiogenic shock (HR 1.121, 95% CI 1.018-1.235, p=0.020). ConclusionThis large-scale, real-world analysis demonstrates that TPVR offers significant short-term advantages with reduced procedural complications compared to SPVR, while outcomes at 5 years are largely comparable between approaches. These findings support TPVR as a viable first-line strategy in anatomically suitable candidates, particularly those at higher surgical risk, while suggesting that patient selection should carefully balance short-term procedural risk against potential long-term considerations.
