Aneurysm III: Interprofessional Care01:26

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...

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...

Aortic 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...

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Cardiac Surgery

Background:

  • Aortic root re-replacement is a complex surgical procedure.
  • This study focuses on a high-risk patient cohort undergoing reoperation.
  • Previous aortic root operations varied, including mechanical and tissue valved conduits, Ross, David, and Yacoub procedures.

Purpose of the Study:

  • To describe the authors' experience with aortic root re-replacement in a high-risk patient cohort.
  • To evaluate the outcomes of complex aortic root reoperations.

Main Methods:

  • A total of 26 patients underwent aortic root re-replacement between 1996 and 2009.
  • Indications for surgery included endocarditis (16 patients), Ross procedure failure (4 patients), valve degeneration (3 patients), anastomotic aneurysm (2 patients), and severe valve insufficiency (1 patient).
  • Reoperations utilized aortic homografts, mechanical conduits, tissue valved conduits, and the David procedure.

Main Results:

  • Mean cardiopulmonary bypass time was 219 minutes, and cross-clamp time was 142 minutes.
  • Mean ICU and hospital stays were 8 and 20 days, respectively.
  • Mortality within 30 days was 8% (2 patients), and 12% (3 patients) required pacemaker implantation.

Conclusions:

  • Aortic root reoperation can be performed with excellent outcomes, even in the presence of endocarditis.
  • Preoperative evaluation, including computed tomography, is crucial for identifying potential challenges during re-sternotomy.
  • Adequate myocardial and organ protection through blood cardioplegia and selective perfusion is essential.
