Summary
Aortic valve repair (AVr) shows good early results and acceptable medium-term outcomes for patients with aortic regurgitation (AR). Concentrating experience in specialist centers is recommended for evolving AVr techniques.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Cardiac Valve Surgery
Background:
- Aortic valve repair (AVr) offers a potential alternative to aortic valve replacement.
- Understanding the early outcomes of various AVr techniques is crucial for surgical decision-making.
Purpose of the Study:
- To evaluate the early results and medium-term outcomes of aortic valve repair (AVr) techniques.
- To assess the safety and efficacy of AVr in patients with aortic regurgitation (AR).
Main Methods:
- Retrospective review of 61 consecutive patients undergoing AVr between 2008 and 2018.
- Procedures included isolated cusp repair, sinotubular junction remodeling, valve-sparing root replacement (VSRR), and hemiroot replacement.
- Analysis of patient demographics, surgical techniques, and postoperative outcomes, including echocardiographic and clinical follow-up.
Main Results:
- 82% of patients had no or mild aortic regurgitation (AR) postoperatively.
- In-hospital survival was 100%, with all patients alive at a mean follow-up of 5.08 years.
- Freedom from re-operation at 8 years was 88.15%, with 18% experiencing moderate AR and 4% severe AR on echocardiography.
Conclusions:
- Aortic valve repair (AVr) achieves good early results and acceptable medium-term outcomes.
- AVr surgery is evolving, suggesting a need for concentrated experience in specialist centers.
- Further research and standardization of AVr techniques are warranted to optimize patient care.

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...

337
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...

401
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...
