Interruption of the aorta with multilobulated arch aneurysms: A new clinicopathologic entity

Progression of arterial toursosity syndrome to multiple aneurysms: Role of defining aortic flow and biomechanics

Arterial tortuosity syndrome (ATS) is a rare aortopathy characterized by multiple areas of tortuosity, stenosis and aneurysms in large and mid-sized arteries. The management of this syndrome is challenging because its complexity and variability in presentation and progression require a thorough understanding of the biological and biomechanical changes that occur in the arterial system. Here we describe, for the first time, the progression of this disease diagnosed in a 3-year old girl and the use of modern imaging modalities including cardiac magnetic resonance (CMR) 4D Flow, 3D modeling, and computational fluid dynamic simulation to characterize the complex aortic flow and its biomechanics. The integration of these modalities with the clinical evaluation will help in our understanding of this disease and provide patient-specific management.

Aortic coarctation complicated with multiple saccular aortic aneurysms

Aortic coarctation is a congenital malformation of the aorta that should be diagnosed and corrected early in life. The natural history of unrepaired coarctation of the aorta includes the development of systemic hypertension and subsequent morbidity and death from cardiovascular disease. Here, we present a case with replacement of the aortic arch and its branches by tortuous multilobulated aneurysms as a result of untreated aortic coarctation.
