Aneurysm III: Interprofessional Care

54
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.

Aortic Regurgitation III: Medical Management01:25

Aortic Regurgitation III: Medical Management

70
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
  • Thoracic Surgery
  • Aortic Surgery

Background:

  • Aortic root aneurysms and dissections often require surgical intervention.
  • Valve-sparing root repair aims to preserve native aortic valve function.
  • Long-term outcomes of anatomic restoration techniques are crucial for patient management.

Purpose of the Study:

  • To evaluate the long-term functional results of valve-sparing aortic root repair.
  • To assess the efficacy of selective sinus replacement in restoring aortic root anatomy.
  • To identify factors influencing long-term valve function after aortic root repair.

Main Methods:

  • A total of 669 patients underwent valve-sparing root repair over an 18-year period.
  • Selective sinus replacement was used, with 1, 2, or 3 sinuses replaced in 209, 234, and 226 patients, respectively.
  • Follow-up averaged 7.1 years, with assessment of aortic insufficiency and root dimensions.

Main Results:

  • Freedom from relevant aortic insufficiency (grade 3+) was 98% at 5 years, 97% at 10 years, and 94% at 15 years.
  • No significant changes in the repaired root's form or size were observed postoperatively.
  • Cusp prolapse/pseudo-prolapse was the sole independent risk factor for recurrent moderate (grade 2+) insufficiency (HR 3.258).

Conclusions:

  • Patient-tailored aortic root repair with sinus replacement yields excellent long-term functional results.
  • The underlying aortic root pathology and annulus size did not significantly impact outcomes.
  • Aortic cusp pathology is the primary determinant of long-term valve function after repair.
