Introduction: Interrupted aortic arch (IAA) is a rare congenital heart defect with a high mortality rate in the neonatal period. Surgical correction of associated intracardiac anomalies can be performed in a one-stage (primary) or two-stage approach.
Objectives: Case review of children with IAA operated in our center and to evaluate the surgical outcomes and the occurrence of complications.
Methods: A retrospective chart review of children operated from June 1998 to October 2006.
Results: Twelve children (nine girls and three boys) were operated. Nine patients had ventricular septal defect with septal malalignment, two had univentricular hearts and two had transposition of the great arteries. Primary correction was performed in eleven patients (aged between two and 38 days), including two Norwood procedures. There was no early mortality. The follow-up time ranged from 30 days to six years (median 2.6 years), with late mortality of 33%. Two children required reintervention for aortic arch restenosis, which was successfully treated by catheterization.
Discussion: Our experience is that early primary repair of IAA has low early and late mortality and is the method of choice most situations. Late mortality depends the severity of associated anomalies.

Outcomes of acute type A aortic dissection repair in patients under the age of 75 versus 75 and older.

Objective: Elderly patients are less likely to undergo surgery for an acute type A aortic dissection (ATAAD). This study aims to understand the risks of surgical treatment in patients 75 and older.
Methods: This was a retrospective study using an institutional database of patients who underwent ATAAD repair from 2007 to 2021.
Sexual dimorphism in pathogenic variant-harbouring individuals.

Background: Individuals harbouring pathogenic variants are at risk for aneurysms/dissections throughout the arterial tree. Based on prior reports of sex differences in thoracic aortic aneurysm/dissection, we investigated the sexual dimorphism for vascular events in variant-harbouring patients.
Methods: We analysed two large pedigrees comprising 84 individuals segregating pathogenic missense variants affecting the same p.
Embolized Transcatheter Aortic Valve Replacement Diagnosed With Transesophageal Echocardiography and a Novel Management Strategy Using a Thoracic Endovascular Aneurysm Repair Stent.

Transcatheter aortic valve replacement (TAVR) is a common treatment for severe aortic stenosis (AS), but it carries the risk of severe complications, including device embolization. We present a case of a TAVR valve embolization into the left ventricular outflow tract (LVOT), diagnosed with transesophageal echocardiography (TEE) shortly after device deployment. The dislodged valve was successfully retrieved from the LVOT into the aorta, flattened, and stabilized with a thoracic endovascular aneurysm repair (TEVAR) stent, enabling the successful implantation of a new TAVR valve.

Article Synopsis
- The study investigates the differences between smooth muscle cells (SMCs) from two lineages in the proximal thoracic aorta, specifically the second heart field (SHF) and cardiac neural crest.
- Researchers used advanced techniques like single-cell RNA sequencing and chromatin accessibility assays to analyze these cells in male mice, identifying distinct gene expressions in both lineages.
- Findings reveal that SHF-derived SMCs have unique transcriptomic profiles that may influence their functions in thoracic aortic diseases, suggesting lineage-specific roles in vascular health.
Literature review analysis of aortitis induced by granulocyte-colony stimulating factor.

Department of Clinical Pharmacy, Weifang People's Hospital, Shandong Second Medical University, Weifang, China.
Background: Recombinant human granulocyte-colony stimulating factors (G-CSF)-induced aortitis is a rare but particularly serious adverse event, commonly seen in cancer patients undergoing chemotherapy. The aim of this article is to clarify the clinical characteristics of G-CSF- induced aortitis and provide effective references for clinical diagnosis and intervention.
Methods: Case reports of adverse reactions of aortitis induced by G-CSF were collected from the relevant databases.
