Staged Complete Revascularization for Coronary Artery Disease vs Medical Management Alone in Patients With AS Undergoing Transcatheter Aortic Valve Replacement

What this study is about

Patients undergoing transcatheter aortic valve replacement (TAVR) often have concomitant coronary artery disease (CAD) which may adversely affect prognosis. There is uncertainty about the benefits and the optimal timing of revascularization for such patients. There is currently clinical equipoise regarding the management of concomitant CAD in patients undergoing TAVR. Some centers perform routine revascularization with percutaneous coronary intervention (PCI) (either before or after TAVR), while others follow an alternative strategy of medical management. The potential benefits and optimal timing of PCI in these patients are unknown. As TAVR expands to lower risk patients, and potentially becomes the preferred therapy for the majority of patients with severe aortic stenosis, the optimal management of concomitant coronary artery disease will be of increasing importance. The COMPLETE TAVR study will determine whether, on a background of guideline-directed medical therapy, a strategy of complete revascularization involving staged PCI using drug eluting stents to treat all suitable coronary artery lesions is superior to a strategy of medical therapy alone in reducing the composite outcome of Cardiovascular Death, new Myocardial Infarction, Ischemia-driven Revascularization or Hospitalization for Unstable Angina or Heart Failure. The study will be a randomized, multicenter, open-label trial with blinded adjudication of outcomes. Patients will be screened and consented for elective transfemoral TAVR and randomized within 96 hours of successful balloon expandable TAVR. Complete Revascularization: Staged PCI using third generation drug eluting stents to treat all suitable coronary artery lesions in vessels that are at least 2.5 mm in diameter and that are amenable to treatment with PCI and have a ≥70% visual angiographic diameter stenosis. Staged PCI can occur any time from 1 to 45 days post successful transfemoral TAVR. Vs. Medical Therapy Alone: No further revascularization of coronary artery lesions. All patients, regardless of randomized treatment allocation, will receive guideline-directed medical therapy consisting of risk factor modification and use of evidence-based therapies. The COMPLETE TAVR study will help address the current lack of evidence in this area. It will likely impact both the global delivery of health care and the management and clinical outcomes of all patients undergoing TAVR with concomitant CAD.

Who can join (things the study team will check)

✅ You may be able to join if…

• Symptomatic aortic valve stenosis prior to TAVR (NYHA Functional Class ≥ 2 OR Abnormal exercise test with severe SOB, abnormal BP response, or arrhythmia) AND
• CAD defined as: at least 1 coronary artery lesion of ≥70% visual angiographic diameter stenosis in a native segment ≥2.5 mm in diameter that is not a CTO and is amenable to treatment with PCI AND
• Consensus by the Local Multidisciplinary Heart Team that the patient is suitable for elective transfemoral TAVR with a balloon expandable transcatheter heart valve AND would receive a bypass with an anastomosis distal to the coronary artery lesion(s) if they were undergoing SAVR. Local Multidisciplinary Heart Teams are expected to follow current clinical guidelines for selection of patients for TAVR with an eligible patient generally expected to have: [AVA ≤ 1.0 cm2 OR AVA index ≤ 0.6 cm2/m2] OR [Jet velocity ≥ 4.0 m/s OR mean gradient ≥ 40 mmHg] OR patients without these criteria may undergo TAVR if the Local Multidisciplinary Heart Team concludes it is appropriate. AND
• Successful transfemoral TAVR, defined as the implantation of a single transcatheter aortic valve within the past 96 hours with freedom from more than minimal aortic insufficiency, stroke, or major vascular complications.

🚫 You may not be able to join if…

• PCI already performed within 90 days prior to TAVR or at the same time as the index transfemoral TAVR procedure
• Planned PCI of coronary artery lesion(s)
• Planned surgical revascularization of coronary artery lesion(s)
• Non-cardiovascular co-morbidity reducing life expectancy to < 5 years
• Any factor precluding 5-year follow-up
• Prior coronary artery bypass grafting surgery or surgical valve replacement
• Severe mitral regurgitation (> 3+)
• Severe left ventricular dysfunction (LVEF < 30%)
• Low coronary takeoff (high risk for coronary obstruction)
• Acute myocardial infarction within 90 days
• Stroke or transient ischemic attack within 90 days
• Renal insufficiency (eGFR < 30 ml/min) and/or renal replacement Rx
• Hemodynamic or respiratory instability
