Study Shows Complete Revascularization May Not Be Essential for Success of TAVR
Revascularization, whether complete or incomplete, following a transcatheter aortic valve replacement (TAVR) procedure did not make a difference in clinical outcomes in elderly patients as long as the revascularization treatment strategy was based on a consensus opinion of a heart team, according to a study published in JACC: Cardiovascular Interventions.
The researchers found no significant differences among the three treatment groups in overall survival and other clinical endpoints, whether patients had complete or incomplete revascularization. Overall, 37 percent of the patients had incomplete revascularization after a TAVR procedure. The one-year mortality rate for patients with complete revascularization was 79.9 percent versus 77.4 percent for patients with incomplete revascularization (p = 0.85).
The investigators concluded that in elderly patients undergoing TAVR for severe aortic stenosis, "A judicious revascularization strategy selected by a dedicated heart team can result in favorable mid-term outcomes, obviating the need for complete coronary revascularization."
