Aneurysm III: Interprofessional Care

43
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 Management

60
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...

Summary

Aortic valve repair using a pericardial patch showed similar mid-term outcomes to repair without a patch. While early reoperation was higher with the patch, long-term valve function and survival were comparable, indicating safety in this aortic valve repair technique.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Valve Repair
  • Biomaterials in Medicine

Background:

  • Aortic valve repair aims to restore valve function and improve patient outcomes.
  • The use of additional materials, such as pericardial patches, in aortic valve repair is a subject of ongoing investigation.
  • Comparing outcomes of repair with and without patches is crucial for optimizing surgical techniques.

Purpose of the Study:

  • To analyze and compare the outcomes of aortic valve repair using a pericardial patch versus repair without additional material.
  • To evaluate the safety and efficacy of aortic valve repair techniques in patients with various aortic conditions.

Main Methods:

  • A cohort study included 618 patients aged over 16 undergoing aortic valve repair with external ring annuloplasty.
  • Data were collected from the AorticValve repair InternATiOnal Registry (AVIATOR) between May 2003 and November 2019.
  • Propensity score analysis (inverse probability of treatment weighting) was used to control for confounders and compare outcomes between groups.

Main Results:

  • Eight-year survival rates were comparable between the patch (92%) and no-patch (90.2%) groups (P=0.957).
  • Early valve-related reoperation was more frequent in the patch group (6% vs 1%, P<0.001).
  • Freedom from aortic valve-related reintervention and structural valve deterioration at 8 years did not differ significantly between groups.

Conclusions:

  • Aortic valve repair with a pericardial patch, using a standardized approach with external annuloplasty, did not increase mid-term reoperation or structural valve deterioration compared to repair without a patch.
  • Despite a higher rate of early reintervention, the pericardial patch is a safe adjunct in aortic valve repair.
  • Effective coaptation height of at least 9 mm is a key factor in successful standardized aortic valve repair.
