Randomized Controlled Trial Multicenter StudyIschemic outcomes after coronary intervention of calcified vessels in acute coronary syndromes. Pooled analysis from the HORIZONS-AMI (Harmonizing Outcomes With Revascularization and Stents in Acute Myocardial Infarction) and ACUITY (Acute Catheterization and Urgent Intervention Triage Strategy) TRIALS.
This study sought to determine the frequency and impact of coronary calcification among patients undergoing percutaneous coronary intervention (PCI) for acute coronary syndromes (ACS). ⋯ Moderate/severe lesion calcification was relatively frequent in patients with non-ST-segment elevation ACS and STEMI and was strongly predictive of stent thrombosis and ischemic TLR at 1 year. (Comparison of Angiomax Versus Heparin in Acute Coronary Syndromes [ACS]; NCT00093158; Harmonizing Outcomes With Revascularization and Stents in Acute Myocardial Infarction; NCT00433966).

Randomized Controlled Trial Multicenter StudyResults of the destination therapy post-food and drug administration approval study with a continuous flow left ventricular assist device: a prospective study using the INTERMACS registry (Interagency Registry for Mechanically Assisted Circulatory Support).
A post-approval (PA) study for destination therapy (DT) was required by the Food and Drug Administration (FDA) to determine whether results with the HeartMate (HM) II (Thoratec, Pleasanton, California) left ventricular assist device (LVAD) in a commercial setting were comparable to results during the DT multicenter pivotal clinical trial. ⋯ Results in a commercial patient care setting for the DT population supported the original pivotal clinical trial findings regarding the efficacy and risk profile of the HM II LVAD. Survival was best in patients who were not inotrope-dependent (INTERMACS profiles 4 to 7).

Outcomes of acute type a dissection repair before and after implementation of a multidisciplinary thoracic aortic surgery program.
The purpose of this study was to compare the results of acute type A aortic dissection (ATAAD) repair before and after implementation of a multidisciplinary thoracic aortic surgery program (TASP) at our institution, with dedicated high-volume thoracic aortic surgeons, a multidisciplinary approach to thoracic aortic disease management, and a standardized protocol for ATAAD repair. ⋯ ATAAD repair can be performed with results approximating those of elective proximal aortic surgery when operations are performed by a high-volume multidisciplinary thoracic aortic surgery team. Efforts to standardize or centralize care of patients undergoing ATAAD are warranted.
