Feasibility and Early Safety of Single-Stage Hybrid Coronary Intervention and Valvular Cardiac Surgery

Abstract

Background: Hybrid percutaneous coronary intervention offers an alternative method of revascularization for high-risk surgical populations. We report the outcomes of a single-stage hybrid strategy in valvular cardiac surgery and explore its effects on operative risk and bleeding.

Methods: In a hybrid operating room, 26 patients underwent hybrid surgery consisting of femoral arterial access, then coronary stenting followed by valve surgery, with appropriate heparin dosing. Clopidogrel (300 mg) was given on anesthesia induction in nonreoperative cases, or at the time of cross clamping (after stenting) for reoperative cases.

Results: Mean follow-up was 680 ± 277 days. The planned coronary stenting and surgery was successful in all patients. Major cardiovascular and cerebrovascular adverse events occurred in 1 patient, with no inhospital deaths observed. No vascular complication or stent thrombosis was observed with the described antiplatelet regimen. Outcomes were comparable to those of standard bypass valve replacement surgery.

Conclusions: This study demonstrates the feasibility and early safety of a single-stage hybrid strategy with coronary stenting followed by valvular surgery in patients at increased surgical risk. Hybrid procedures may lower operative risk by eliminating or reducing the need for bypass grafting.
