Background Prior cardiac surgery (PCS) is associated with increased surgical risk and post-operative complications following surgical aortic valve replacement (SAVR), but whether this risk is similar in transcatheter aortic valve replacement (TAVR) is unclear.
Objectives We sought to further evaluate clinical outcomes in patients with and without PCS.
Methods In the PARTNER 2A trial, 2032 patients with severe AS at intermediate surgical risk were randomized to TAVR with the SAPIEN XT valve or SAVR. Adverse clinical outcomes at 30-days and 2-years were compared using Kaplan Meier event rates and multivariable Cox proportional hazards regression models. The primary end point of the PARTNER 2 trial was all cause death and disabling stroke.
Results 509 patients (25.1%) had PCS, mostly (98.2%) coronary artery bypass grafting (CABG). There were no significant differences between TAVR and SAVR in patients with or without PCS, in the rates of the primary endpoint at 30 days or 2 years. Nevertheless, an interaction was observed between PCS and treatment arm; while no-PCS patients treated with TAVR had higher rates of 30-day major vascular complications than patients treated with SAVR (adjusted HR 2.66, 95% CI 1.68-4.22), the opposite is true for patients with PCS (adjusted HR 0.27, 95% CI 0.11-0.66) (pinteraction<0.0001). A similar interaction was observed for life threatening or disabling bleeding.
Conclusions In the PARTNER 2A Trial of intermediate-risk patients with severe AS undergoing SAVR versus TAVR, the relative risk of two-year adverse clinical outcomes were similar between TAVR and SAVR in patients with or without PCS.
