An old surgical technique is making a major comeback. A new study found that patients who underwent the Ross procedure — replacing a diseased aortic valve with the patient's own pulmonary valve — had survival rates matching the general healthy population at 12 years. With remarkably low reintervention rates and strong durability, experts are calling it the new gold standard for aortic valve replacement in experienced hands.
An old surgical technique is making a major comeback. The Ross procedure, first described in 1967 but largely abandoned in the early 2000s, is being hailed as a potential new gold standard for aortic valve replacement. A study of 455 patients published in the Journal of the American College of Cardiology found that those who underwent the procedure had survival rates comparable to the healthy general population after 12 years — something no other aortic valve replacement approach has consistently achieved.
The procedure works by replacing the diseased aortic valve with the patient's own pulmonary valve (a "living valve"), which preserves natural blood flow dynamics and allows patients to handle high cardiac output during exercise — something prosthetic valves can't match. Experts note the benefits held up even in patients over 50, expanding its potential candidate pool.
By the Numbers:
Why it matters: Despite the impressive results, the Ross procedure remains a Class IIB recommendation in current ACC/AHA guidelines — but that may soon change. Experts caution it's technically demanding and outcomes are heavily tied to surgical volume and experience, underscoring the need for quality metrics and centralized expertise.
