Aneurysm III: Interprofessional Care

Aneurysm III: Interprofessional Care

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. This...

Aneurysm I: Introduction

Aneurysm I: Introduction

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...

Aortic Regurgitation III: Medical Management

Aortic 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...

Area of Science:

Cardiovascular Surgery
Biomaterials Science

Background:

Left ventricular aneurysm repair is a critical cardiac procedure.
The CorRestore patch was utilized for left ventricular aneurysm repair in these cases.

Observation:

Two patients developed left ventricular pseudoaneurysms post-CorRestore patch repair.
These pseudoaneurysms necessitated further surgical intervention.

Findings:

The CorRestore patch exhibited physiologic limitations contributing to pseudoaneurysm formation.
Dacron patches were successfully employed for subsequent pseudoaneurysm repair.

Implications:

Understanding CorRestore patch limitations is crucial for preventing post-repair complications.
This study informs surgical choices for left ventricular aneurysm and pseudoaneurysm repair.
