Patients with concomitant AS and CAD can be treated by catheter or surgery.
Patients treated by catheter have a higher co-morbidity burden.
The surgical approach is associated with a higher rate of procedural complications.
Patients treated by catheter have similar late outcomes to those treated by surgery.
Two therapeutic strategies are available when aortic stenosis and coronary artery disease coexist: a transcatheter approach, with percutaneous coronary intervention followed by transcatheter aortic valve replacement; and a surgical approach, consisting of surgical aortic valve replacement combined with coronary artery bypass graft.
We sought to compare the outcomes of these two strategies.
The study population consisted of 241 patients who benefited from aortic valve replacement and coronary revascularization (transcatheter, n=150; surgery, n=91).
Patients in the transcatheter population were older (83.5 vs. 71.8years; P<0.001) and had a higher Logistic EuroSCORE (11.1% vs. 5.7%; P<0.001). At 30days postprocedure, patients who had surgery exhibited more life-threatening bleedings (12.1% vs 4.5%; P=0.034), acute kidney injury (12.1% vs. 1.3%; P<0.001) and atrial fibrillation (55.6% vs. 8.7%; P<0.001). After a median follow-up of 27months, the risk of major adverse cardiovascular or cerebrovascular events did not differ significantly between the two strategies (hazard ratio [HR] 1.41, 95% confidence interval [CI] 0.97–2.04; P=0.07), whereas estimated glomerular filtration rate<60mL/min (HR 2.22, 95% CI 1.58–3.12; P<0.001), peripheral artery disease (HR 2.00, 95% CI 1.37–2.91; P<0.001) and left ventricular ejection fraction<50% (HR 1.69, 95% CI 1.12–2.55; P=0.012) were associated with a negative prognosis.
In our study, patients with aortic stenosis and coronary artery disease treated by catheter were older and had a higher co-morbidity burden than those treated by surgery. The surgical strategy was associated with a higher rate of 30-day complications, but long-term outcomes were similar between the two strategies.Le texte complet de cet article est disponible en PDF.
