Urgent surgery for acute aortic root dissecting aneurysms is recommended. Elective surgery for aortic aneurysms over 5 cm is advised, with a 3.03% hospital mortality rate in this study of aortic root replacement.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Aortic Surgery

Background:

  • Aortic root aneurysms and dissections pose significant risks.
  • Aortic valve regurgitation is a common complication.
  • Surgical intervention is crucial for managing these conditions.

Purpose of the Study:

  • To detail the surgical experience with aortic root replacement in 231 patients.
  • To discuss current indications, methods, and techniques for aortic root aneurysm surgery.

Main Methods:

  • A retrospective review of 231 patients undergoing aortic root replacement between 1994 and 1999.
  • Patients included those with isolated aneurysms and DeBakey types I and II aortic dissections.
  • Composite valved grafts were used in most cases.

Main Results:

  • Hospital mortality rate was 3.03%.
  • Early complications included bleeding, pericardial effusion, and neurological events.
  • Significant reduction in left ventricular end-diastolic diameter post-surgery.

Conclusions:

  • Prompt surgery is indicated for acute aortic root dissecting aneurysms.
  • Aortic aneurysms >5 cm, with or without chronic dissection, warrant surgical intervention.
