Right coronary artery takeoff plane and implications for brachiocephalic interventions and next generation transcatheter aortic valve intervention embolic protection devices.
J Invasive Cardiol
September 2025
Newark Beth Israel Medical Center, Newark, New Jersey.
Objectives: The authors hypothesized that the origin of the right coronary artery (RCA) is a direct continuation of the major aortic arch branches (MAAB) takeoff plane, which may have implications for brachiocephalic interventions and next generation transcatheter aortic valve intervention (TAVI) embolic protection devices (EPDs).
Methods: In this single-center, retrospective, cross-sectional study, the authors analyzed computed tomographic angiography (CTA) images from 92 patients undergoing TAVI evaluation to determine the spatial relationship between the origin of the RCA and the MAAB takeoff plane. Patients with prior cardiothoracic or aortic interventions and those with anomalous RCA origin were excluded.
Survival after aberrant left subclavian artery-esophageal fistula hemorrhage: A case report and technique review.
J Vasc Surg Cases Innov Tech

Department of Vascular Surgery, Baptish Health, Birmingham, AL.
Subclavian artery-esophageal fistula is a rare but potentially fatal vascular anomaly. Inherent to Downs syndrome, trisomy 21 presents with a variety of rare cardiac and vascular anomalies. Subclavian-esophageal fistulae are rare and often fatal complications of a right-sided aortic arch.

Interv Radiol (Higashimatsuyama)
August 2025
Department of Diagnostic Radiology, National Cancer Center Hospital, Japan.
Purpose: To determine how the anatomical morphology of the left subclavian artery and aortic arch affects the technical difficulty of navigating the aortic arch during left transradial access for visceral vascular interventions.
Material And Methods: We retrospectively evaluated 98 patients who underwent visceral vascular interventions using left transradial access from January 2022 to December 2022. Cannulation of the descending aorta was considered difficult when the time required to manipulate the catheter in the aortic arch exceeded 30 seconds.
Right thoracotomy for surgical repair of Kommerell's diverticulum with a right-sided aortic arch and aberrant left subclavian artery: a video case report.
Multimed Man Cardiothorac Surg
September 2025
Kawasaki Aortic Center, Kawasaki Saiwai Hospital, Kawasaki, Japan.
Kommerell's diverticulum (KD) combined with a right-sided aortic arch (RAA) and an aberrant left subclavian artery (ALSA) is a rare congenital vascular anomaly causing significant compressive dysphagia. Treatment options, including open surgery, thoracic endovascular aortic repair and hybrid approaches, are debated due to anatomical complexities. We report a 48-year-old female with dysphagia from symptomatic KD, RAA and ALSA, clearly delineated by preoperative computed tomography angiography.

Epithelioid hemangioendothelioma (EHE) is an exceptionally rare vascular tumor with an incidence of <1/million people/year. This case report describes a patient who initially presented with progressive left-sided neck swelling and dysphagia and was found to have EHE at the confluence of the left subclavian and internal jugular veins. Diagnosis was confirmed with a core needle biopsy after an initial inconclusive fine-needle aspiration.
