Pericardium and polytetrafluoroethylene are popular patch materials, although they have some deficits in use for thin and small vessels. We present a case of post-Norwood hypoplastic left heart syndrome that required enlargement of the anastomosis between the native ascending aorta and the neoaorta at the time of a bidirectional Glenn procedure. The azygos vein was a useful material for patch augmentation of a hypoplastic ascending aorta.

Due to the limited evidence surrounding this condition, existing guidelines are limited in the complexity of their recommendations. While most patients are initially managed medically, invasive treatment becomes necessary in a large proportion of patients.

Malperfusion in Patients with Acute Type A Aortic Dissection: A Nationwide Analysis.

Ann Thorac Surg

January 2025

Division of Cardiovascular Surgery, University of Pennsylvania, Philadelphia, PA; Leonard Davis Institute, University of Pennsylvania, Philadelphia, PA; Penn Cardiovascular Outcomes, Quality, & Evaluative Research Center, Philadelphia, PA.

Background: This study describes in detail the clinical burden of malperfusion associated with acute Type A aortic dissection (ATAAD) in a large, national cohort and the effect of treatment strategy on outcomes.

Methods: All patients undergoing repair of ATAAD between 2017 and 2020 in the Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database were studied. Malperfusion was defined using STS definitions based on imaging or surgeon's evaluation.

Background: Anatomic considerations of transcatheter aortic valve implantation (TAVI) have an important role for the procedure planning, but sex-specific data are lacking.

Methods: All eligible cases undergoing evaluation for TAVI procedure in the period from November 2019 to July 2023 at the University Hospital of Split were included. Cardiac computed tomography was analysed to derive the measures of left ventricular outflow tract (LVOT), aortic root, ascending aorta, and ilio-femoral arteries.
