LOng-Term Fate of Moderate Aortic Regurgitation Left Untreated at the Time

Status Completed

Clinical Trial Summary

Multivalvular heart disease is a highly prevalent clinical condition that comprises 14.6% of the patients undergoing valvular surgery. Specifically, aortic valve regurgitation (AR) can be present in a considerable proportion of patients undergoing mitral valve (MV) surgery. In the Society of Thoracic Surgeons database, con- comitant aortic and mitral surgery accounted for 57.8% of the total multivalvular procedures with an unadjusted mortality rate of 10.7%. When both the aortic and MVs exhibit severe disease, con- comitant valve surgery is well-accepted by the surgical commu- nity and supported by current guidelines. On the other hand, when the aortic valve (AV) shows only moderate regurgita- tion, which would not be surgically treated if singly present, the appropriate management of the AV pathology at the time of MV surgery is still under debate. The American College of Cardiology guidelines state that aortic valve replacement (AVR) is reasonable (class IIa) in patients with moderate AR (stage B) while undergoing surgery on the ascend- ing aorta, a coronary artery bypass graft or MV surgery (level of evidence: C). Conversely, the latest European Society of Cardiology guidelines on valvular heart disease define as con- troversial the decision to treat the AV in patients with moderate AR who undergo MV surgery, considering the slow progression of this disease. In this group of patients, they advocate a heart team approach that will take into account the aetiology of AR, the life expectancy of the patient, the operative risk and other clinical factors. This disagreement may lead to uncertainty about how patients with less than severe AR should be managed during MV surgery, especially considering the burden of double-valve surgical procedures. The goal of this study is to evaluate the immediate and long- term outcomes, including the need for a new procedure on the AV, in patients with moderate AR at the time of MV surgery.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
