Background: Outcomes from transcatheter aortic valve replacement (TAVR) in low-surgical risk patients with bicuspid aortic stenosis beyond 2 years are limited.

Objectives: This study aimed to evaluate 3-year clinical and echocardiographic outcomes from the Evolut Low Risk Bicuspid Study.

Methods: The Evolut Low Risk Bicuspid Study is a prospective, multicenter, single-arm study conducted in 25 U.

Background: Randomized data comparing outcomes of transcatheter aortic valve replacement (TAVR) with surgery in low-surgical risk patients at time points beyond 2 years is limited. This presents an unknown for physicians striving to educate patients as part of a shared decision-making process.

Objectives: The authors evaluated 3-year clinical and echocardiographic outcomes from the Evolut Low Risk trial.

Background: Cancer and ischemic stroke are associated with significant morbidity and mortality. Hypercoagulability, disseminated intravascular coagulation, venous-to-arterial embolism, and non-bacterial thrombotic endocarditis are among recognized mechanisms. Emboli to the brain, or to other organs, are known to occur as a consequence of liberated thrombotic debris originating from the thrombogenic surface of intracardiac neoplastic entities.

Endovascular aneurysm repair has considerable potential advantages over the surgical approach as a treatment for thoracic aortic rupture, in part because open surgical repair of ruptured thoracic aortic aneurysms is associated with high mortality and morbidity rates. We describe the successful endovascular deployment of stent-grafts to repair a contained rupture of a descending thoracic aortic aneurysm in an 86-year-old man whose comorbidities prohibited surgery. Two months after the procedure, magnetic resonance angiography showed a patent stent-graft, a patent left subclavian artery, and complete exclusion of the aneurysm.
