Hemodynamic Effects of Valve Asymmetry in Sapien 3 Transcatheter Aortic Valves.

Background: Eccentric valve deployment after transcatheter aortic valve replacement (TAVR) has been associated with abnormal leaflet shear stresses that may accelerate structural valve deterioration (SVD). This phenomenon has not been studied in patients receiving Sapien 3 prostheses (Edwards Lifesciences).

Methods: A retrospective cohort analysis of 100 patients who received Sapien 3 valves between 2013 and 2015 at a single institution was performed.

Contemporary Antiplatelet Pharmacotherapy in the Management of Acute Coronary Syndromes.

Purpose Of Review: Antiplatelet therapies are pivotal treatments in the management of acute coronary syndrome (ACS) with or without revascularization. In recent years, the use of P2Y12 antagonists prior to catheterization, so-called pretreatment, has been questioned, particularly in patients who may be at higher bleeding risks. The purpose of this review was to evaluate the current literature on contemporary and novel antiplatelet therapy in the pretreatment and treatment of ACS.

Robotic-assisted percutaneous coronary intervention.

Performance of percutaneous coronary intervention (PCI) is associated with several occupational hazards including radiation exposure and musculoskeletal injury. Current methods to mitigate these risks range from suspended radiation suits to adjustable lead-lined glass shields. Robotic-assisted PCI is a novel approach to PCI that utilizes remote-controlled technology to manipulate catheters thereby significantly reducing radiation exposure to the operator and catheterization laboratory staff.

Catechins as Potential Mediators of Cardiovascular Health.

The impact of diet on cardiovascular disease has become an increasingly relevant topic as ongoing epidemiological evidence continues to demonstrate clear associations with disease burden and mortality. Certain diets, such as those high in sodium and saturated fat, are associated with cardiovascular disease states, while other diets can be cardioprotective. However, there is limited knowledge on how the micro- and macronutrients within such cardioprotective diets afford their benefits.
