Nonsyndromic Thoracic Aortic Aneurysm and Dissection: Outcomes With Marfan Syndrome Versus Bicuspid Aortic Valve Aneurysm.

Background: Genetic aortopathy (GA) underlies thoracic aortic aneurysms (TAA) in younger adults. Comparative survival and predictors of outcomes in nonsyndromic TAA (NS-TAA) are incompletely defined compared to Marfan syndrome (MFS) and bicuspid aortic valve (BAV).

Objectives: The study sought to compare survival and clinical outcomes for individuals with NS-TAA, MFS, and BAV.

Extracorporeal membrane oxygenation for very high-risk transcatheter aortic valve implantation.

Background: Transcatheter aortic valve implantation (TAVI) can cause profound haemodynamic perturbation in the peri-operative period. Veno-arterial extracorporeal membrane oxygenation (ECMO) can be used to provide cardiorespiratory support during this time, either prophylactically or emergently.

Method: 100 TAVI procedures were performed between 2009 and 2013 in our institution.
