Summary
Aortic valve neocuspidization (AVNeo) shows promising early and midterm surgical outcomes in patients under 65. Long-term results and reliability require further verification for this younger patient group.
Area of Science:
- Cardiovascular Surgery
- Cardiac Valve Repair
- Aortic Valve Disease
Background:
- Aortic valve neocuspidization (AVNeo) is an alternative surgical technique for aortic valve disease.
- Outcomes in younger patients (<65 years) undergoing AVNeo require specific evaluation.
Purpose of the Study:
- To assess the surgical outcomes of aortic valve neocuspidization (AVNeo) in patients under 65 years old.
- To evaluate early and midterm results in this specific demographic.
Main Methods:
- AVNeo was performed on 168 patients from December 2010 to February 2019; 36 patients were under 65.
- The cohort included patients with aortic regurgitation (AR) and aortic stenosis (AS).
- Concomitant procedures included coronary artery bypass grafting, mitral valve procedures, and ascending aorta replacement.
Main Results:
- No conversions to valve replacement were necessary; two in-hospital deaths occurred in emergent cases.
- Postoperative gradients significantly decreased in the AS group, and AR was resolved or trivial in most AR patients.
- Freedom from reoperation rates were 100% at 36 months and 93% at 60 months.
Conclusions:
- AVNeo demonstrates suitability for patients under 65 based on early and midterm outcomes.
- Further long-term follow-up is essential to confirm the durability and reliability of AVNeo in this population.

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

01:15Aortic Regurgitation I: Introduction
371
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

312
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

01:27Mitral Valve Prolapse I: Introduction
283
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

01:22Mitral Stenosis I: Introduction
330
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage.
