Aims: To explore the feasibility, safety, and efficacy of 1-stop treatment of percutaneous left atrial appendage occlusion (LAAO) combined with coronary intervention for patients with nonvalvular atrial fibrillation (AF) complicated with coronary heart disease (CHD).
Methods and results: We retrospectively analyzed the clinical data of 6 patients with AF combined with CHD admitted from Zhuhai People's Hospital from April 2017 to June 2018. After the operation, all patients were treated with aspirin (100 mg qd) and clopidogrel (75 mg qd) for 1 year, which is considered long-term use of aspirin/clopidogrel. The effects of LAAO and coronary intervention were evaluated immediately. The location of the left atrial appendage occluder, thrombosis, residual leak, and clinical manifestations were observed during the 90-day follow-up. The patients were implanted with Watchman™ devices and coronary stents. After the operation, the immediate sealing effect was satisfactory. The Watchman occluder was used in accordance with the PASS principle (position, anchor, size, seal), and the coronary intervention was satisfactory. During the operation, there were no device-related thrombosis, tamponade, or vascular complications. Follow-up results showed that in the 6 patients, there were no hemorrhagic strokes, worsening heart function, residual leakage, device-related thrombosis, angina pectoris, myocardial infarction, skin ecchymosis, gastrointestinal bleeding, or cerebral hemorrhage.
Conclusion: For patients with nonvalvular AF combined with CHD, the safety and feasibility of 1-stop treatment with left atrial appendage and coronary intervention are reliable, and the curative effects were also satisfactory at short- and medium-term follow-up.
