Valve-sparing procedure for acute aortic regurgitation due to intimal intussusception in a minimally localized aortic root dissection.

Background: Acute heart failure due to aortic regurgitation (AR) is a severe comorbidity of type A acute aortic dissection (AAD). Valve-sparing aortic root replacement is typically performed when the aortic valve remains intact.

Case Presentation: A 33-year-old male presented to our hospital with chest pain.

Initial thickness of the crescent may not be a reliable predictor of complications in type A intramural haematoma.

Objectives: This study aimed to investigate changes in haematoma thickness during the early period and their association with disease progression in patients who received initial medical treatment for type A intramural haematoma (IMH).

Methods: Medical records and serial computed tomography angiography (CTA) images of patients who did not undergo emergency aortic repair for type A IMH upon presentation were retrospectively reviewed. The haematoma remodelling rate was determined using the following equation: thickness of the haematoma on the first CTA (mm) - thickness of the haematoma on the second CTA (mm)time between the first and second CTAs (h).

Watch-and-wait strategy for selected patients with type A intramural hematoma.

Objective: This single-center retrospective study evaluated early and midterm outcomes of 100 consecutive patients with type A intramural hematoma.

Methods: Initial watch-and-wait strategy was indicated if the maximum aortic diameter was < 50 mm, pain score was < 3/10 on the numerical rating scale, and no ulcer-like projection was observed in the ascending aorta. The primary endpoints of this study were all-cause and aorta-related deaths, and the secondary endpoint was aortic events.
