Introduction: Minimally invasive and hybrid procedures for patients with aortic valve pathology and coronary artery disease are innovative solutions. Aim: To report the results of hybrid aortic valve replacement through right anterior minithoracotomy (RT-AVR)/percutaneous coronary intervention (PCI) and conventional aortic valve replacement (AVR)/coronary artery bypass grafting (CABG) surgery for patients with aortic valve and coronary artery disease. Material and methods: Analysis of prospectively gathered data of 187 patients - 86 hybrid and 101 conventional procedures. For 21 patients, RT-AVR was followed by PCI during the same session, and for 65 patients RT-AVR was performed within 90 days of PCI. Results: Hospital mortality in the AVR/CABG and RT-AVR/PCI groups was 3.0% and 1.2%, respectively (p = 0.237). Complications occurred in 18.6% of patients in the RT-AVR/PCI group and 33.7% in the AVR/CABG group (p = 0.020). Two-stage RT-AVR/PCI was performed due to ACS (100%); one-stage was due to the intention to perform a minimally invasive procedure instead of AVR/CABG (71.4%) or due to replacing CABG with PCI because of a lack of vascular grafts for CABG (19.1%). In 38.5% of patients from the two-stage subgroup, antiplatelet therapy was stopped before RT-AVR, 32.3% of patients from the two-stage subgroup were on single, and 29.2% on dual antiplatelet therapy until RT-AVR, which had no influence on postoperative blood requirements or postoperative myocardial infarction (p = 0.410 and p = 0.077, respectively). Conclusions: The hybrid procedure presented in our series showed similar mortality and morbidity results and may be an alternative to conventional AVR and CABG through full sternotomy in selected patients.
