The increasing fear of acquired immune deficiency syndrome and other blood-transmissible diseases and increasing blood-bank shortages prompted a study of the safety and feasibility of a commercially available hand-held unit for collecting and reinfusing blood. The device was used on nine patients undergoing aortic surgery and permitted a mean saving of 2.6 units of banked blood. The reinfusion of collected blood did not result in any coagulation disturbances or changes in renal function. The hemoglobin and platelet levels were comparable to those in a group of patients receiving only banked blood. The unit does not require additional personnel or technical training for its use. The authors conclude that this autotransfusion device is a safe and feasible method of reducing the requirement for banked blood during aortic surgery.

Extensive Arterial Dissection: A Rare Multivascular Emergency.
Cureus
December 2024
Internal Medicine, Hospital de Braga, Braga, PRT.
Aortic dissection is a life-threatening vascular emergency associated with high morbidity and mortality. Clinical manifestations might include severe chest pain to neurological deficits, depending on the arterial segments involved. Extensive dissections involving multiple aortic segments and branch vessel occlusions, such as the carotid arteries, are rare and pose unique diagnostic and therapeutic challenges.

Anatomically corrected malposition (ACM) of the great arteries is an exceedingly rare congenital heart disease. This conotruncal anomaly manifests with an L-malposition of the aorta (situs solitus, D loop, aorta to the left of the pulmonary artery) with normal ventriculoarterial concordance. A 14-month-old boy presented with an ACM associated with a ventricular septal defect that was successfully repaired.

Heart, Vascular, and Thoracic Institute, Cleveland Clinic London, London, United Kingdom.
We describe the case of a 52-year-old man with radiation-induced severe mixed aortic and mitral valve disease, thickening of the aortomitral continuity, mitral annular calcification, and porcelain aorta with limited transcatheter treatment options. By replacing the aorta during circulatory arrest, we demonstrate that it is possible to clamp the ascending aorta to facilitate prosthetic aortic and mitral valve replacement.

JACC Adv
February 2025
Department of Internal Medicine II, Medical University of Vienna, Vienna, Austria.
Background: Degenerative severe aortic stenosis (AS) is treated by valve replacement to improve outcome. Despite diagnostic advancements, many AS patients are still diagnosed late with advanced heart failure.
Objectives: The aim of the study was to assess multiorgan dysfunction in severe AS using blood biomarkers and their association with quantitative fluid levels and clinical outcomes after transcatheter aortic valve implantation (TAVI).
Hybrid repair of aortic aneurysm in a patient with a congenital pelvic kidney.
J Vasc Surg Cases Innov Tech
April 2025
Libin Cardiovascular Institute, University of Calgary, Calgary, Alberta, Canada.
We describe a patient with an asymptomatic infrarenal abdominal aortic aneurysm. Treatment decisions were complicated by the presence of a left congenital pelvic kidney supplied by two renal arteries originating from the proximal common iliac arteries bilaterally and respiratory status that was prohibitive to open repair. A hybrid surgical repair was performed with a bifurcated aortic endograft and parallel grafting to revascularize the pelvic renal arteries.
