Summary
A patient developed a pseudoaneurysm after aortic root replacement. Redo surgery with a custom graft and modified Cabrol technique successfully addressed this complication.
Area of Science:
- Cardiovascular Surgery
- Medical Devices
- Aortic Surgery
Background:
- Aortic root replacement using bioprosthetic devices can be complicated by pseudoaneurysm formation.
- Late complications following aortic root surgery require careful diagnosis and management.
Purpose of the Study:
- To describe a case of aortic root pseudoaneurysm following stentless bioprosthetic root replacement.
- To detail the surgical technique for redo aortic root replacement using a custom composite graft and modified Cabrol procedure.
Main Methods:
- Diagnosis of a large aortic root pseudoaneurysm was confirmed using computed tomography and transesophageal echocardiography.
- Redo aortic root replacement was performed using a customized Dacron tube/valve composite graft.
- A proximal "skirt" and a modified Cabrol technique were incorporated into the surgical repair.
Main Results:
- The patient presented with symptoms of shortness of breath and a new systolic murmur.
- Imaging revealed a large, complex aortic root pseudoaneurysm.
- Successful redo aortic root replacement was achieved using the described custom graft and technique.
Conclusions:
- Redo aortic root replacement with a customized composite graft and modified Cabrol technique is a viable option for managing complex pseudoaneurysms.
- This approach can effectively address late complications after initial aortic root bioprosthetic implantation.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

01:15Aortic Regurgitation I: Introduction
1.2K
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...

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...
