Aortic valve replacement has traditionally been the treatment of choice for patients with aortic valve insufficiency with or without aortic root pathology. Aortic valve repair is emerging as an attractive treatment alternative that avoids the long-term risks associated with prosthetic valve implantation including thromboembolism, endocarditis, prosthetic valve deterioration, and anticoagulation related hemorrhage. Important achievements in this discipline have occurred over the past decade including development and refinement of valve preserving aortic root replacement techniques, development of a classification system for aortic insufficiency, surgical approaches to cusp disease with varying cusp anatomy. As surgical techniques for aortic valve repair continue to evolve, clinical outcomes up to and beyond the first decade are promising with excellent survival and low risk of valve related events.

Based on several randomized clinical trials, carotid revascularization has been shown to reduce future stroke risk among individuals with severe asymptomatic carotid stenosis. However, a well-recognized problem with such prophylactic intervention is the risk of periprocedural stroke, death, or myocardial infarction. If actual stroke risk with asymptomatic carotid stenosis can be reduced significantly by aggressive medical management, carotid revascularization may yield marginal benefit or even cause harm especially in those with limited life expectancy. ⋯ Others feel such conclusions cannot be made with observational data alone. In the midst of this controversy, it is important that clinicians perform carotid revascularization on a case by case basis while ensuring optimal medical management in all patients. An algorithmic approach to decision making based on available evidence will enable clinicians to personalize patient management with efficiency.
