Reconstruction of the aortic valve for aortic regurgitation (AR) remains challenging, in part because of not only cusp or root pathology but also a combination of both can be responsible for this valve dysfunction. We have systematically tailored the repair to the individual pathology of cusps and root. ⋯ Aortic valve repair is feasible even for complex mechanisms of AR with a systematic and individually tailored approach. Operative mortality is low and mid-term durability is encouraging. The incidence of valve-related morbidity is low compared with valve replacement.

Comparative Study
Differences in clinical presentation, management, and outcomes of acute type a aortic dissection in patients with and without previous cardiac surgery.
There are less data on the clinical and diagnostic imaging characteristics, management, and outcomes of patients with previous cardiac surgery (PCS) presenting with acute type A aortic dissection (AAD). ⋯ Our study highlights differences in clinical characteristics, management, and outcomes of AAD patients with PCS. Importantly, PCS, with the exception of previous AVR, does not adversely influence early outcomes of AAD patients, including those undergoing surgical repair. However, because of otherwise dismal outcomes with medical management of AAD, our data indicate that a history of PCS (even that of previous AVR) should not preclude physicians from recommending surgical correction of type A aortic dissection in appropriate patients.

Extensive left ventricular (LV) remodeling may not allow functional recovery after revascularization, despite the presence of viable myocardium. ⋯ Extensive LV remodeling prohibits improvement in LVEF after revascularization and affects long-term prognosis negatively, despite the presence of viability.

Randomized Controlled Trial Multicenter Study Clinical Trial
Benefits and risks of the combination of clopidogrel and aspirin in patients undergoing surgical revascularization for non-ST-elevation acute coronary syndrome: the Clopidogrel in Unstable angina to prevent Recurrent ischemic Events (CURE) Trial.
Antiplatelet therapy and antithrombin therapy have been demonstrated to reduce the risk of cardiac events in patients presenting with acute coronary syndrome, yet all effective therapies also increase the risk of bleeding. ⋯ The benefits versus risks of early and long-term clopidogrel therapy (freedom from CV death, MI, stroke, or life-threatening bleeding) are similar in those undergoing revascularization (CABG or PCI) and in the study population as a whole. Overall, the benefits of starting clopidogrel on admission appear to outweigh the risks, even among those who proceed to CABG during the initial hospitalization.

Comparative Study
Impact of the metabolic syndrome on mortality from coronary heart disease, cardiovascular disease, and all causes in United States adults.
Mortality resulting from coronary heart disease (CHD), cardiovascular disease (CVD), and all causes in persons with diabetes and pre-existing CVD is high; however, these risks compared with those with metabolic syndrome (MetS) are unclear. We examined the impact of MetS on CHD, CVD, and overall mortality among US adults. ⋯ CHD, CVD, and total mortality are significantly higher in US adults with than in those without MetS.
