Summary
Aortic root replacement using the Bentall de Bono procedure shows satisfactory long-term results. However, survival is reduced in patients with Marfan syndrome or those requiring aortic reclamping during surgery.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Surgical Outcomes
Background:
- Analyzing long-term outcomes of aortic root replacement procedures.
- Identifying factors influencing long-term mortality after aortic root surgery.
Purpose of the Study:
- To evaluate the long-term results of aortic root replacement using the Bentall de Bono procedure.
- To determine factors affecting mortality in patients undergoing this surgery.
Main Methods:
- 254 patients underwent aortic root replacement with the Bentall de Bono procedure between June 1993 and November 2008.
- Concomitant procedures, indications for surgery (aneurysm, Marfan syndrome), and intraoperative events (aortic reclamping) were recorded.
- Follow-up averaged 6.3 years, with actuarial survival rates calculated.
Main Results:
- In-hospital mortality was 11.8%, with low cardiac output being the primary cause.
- Late mortality was 2.8%. Neurologic complications occurred in 6.3% of patients.
- Marfan syndrome and intraoperative aortic reclamping were significant predictors of late mortality.
Conclusions:
- The modified Bentall de Bono procedure for aortic root replacement yields satisfactory long-term outcomes.
- Patient survival is negatively impacted by the presence of Marfan syndrome and the need for aortic reclamping.
- The study highlights key risk factors for mortality in this patient population.

01:25Aortic Regurgitation III: Medical Management
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...
01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
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
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...
