Bicuspid aortic valve and/or coarctation of the aorta are consistently associated with ascending aortic and para-coarctation medial abnormalities. Medial abnormalities in the ascending aorta are prevalent in other types of patients with a variety of forms congenital heart disease (CHD), such as single ventricle, persistent truncus arteriosus, transposition of the great arteries, hypoplastic lef...
OBJECTIVE To determine whether F-fluorodeoxyglucose (F-FDG) micro-positron emission tomography (micro-PET) can predict abdominal aortic aneurysm (AAA) rupture. BACKGROUND An infrarenal AAA model is needed to study inflammatory mechanisms that drive rupture. F-FDG PET can detect vascular inflammation in animal models and patients. METHODS After exposing Sprague-Dawley rats to intra-aortic po...
Catastrophic ascending aorta aneurysm (AsAA) dissection and rupture can be prevented by elective surgical repair, but identifying individuals at risk remains a challenge. Typically the decision to operate is based primarily on the overall aneurysm size, which may not be a reliable indicator of risk. In this study, AsAA inflation and rupture was simulated in 27 patient-specific finite element mo...
BACKGROUND Iatrogenic damage of different structures of the aortic root, in the region of the so-called "device landing zone," may occur during transcatheter aortic valve implantation (TAVI). It is mostly considered difficult to treat or even untreatable. METHODS AND RESULTS We performed a retrospective analysis of the occurrence, clinical presentation, treatment, and outcome of iatrogenic ru...
“There is no disease more conducive to clinical humility than aneurysm of the aorta.” These words of Sir William Osler still resonate today, when many patients with ruptured abdominal aortic aneurysms die before reaching the hospital and the mortality rate among those who reach the hospital can exceed 50 percent. The prevention of rupture through early detection and elective repair remains the ...
Aortic rupture has a high mortality rate and can be considered a medical emergency. The standard treatment for aortic rupture is surgical repair. An aortic stent graft for a ruptured descending aorta is considered an effective alternative treatment. However, an aortic stent graft is difficult when the aortic aneurysm is in the aortic arch due to supra-aortic vessels. We report on a patient with...
Aortic dissection is characterized by a tear or rupture in the intimal layer of aorta causing blood to flow between layers arterial wall, thus separating them. While cardiopulmonary resuscitation (CPR) life-saving intervention, it can unintentionally contribute development worsening aortic dissection. The forceful chest compressions involved CPR put significant pressure on fragile potentially l...
We present the findings in a 57-year-old man with a rupture of the thoracic aorta that originated in a penetrating atherosclerotic aortic ulcer. It formed a large hematoma that clinically mimicked a true saccular thoracic aneurysm. The possibility of penetrating aortic ulcer should be considered in the differential diagnosis of aortic aneurysm.
