There are limited data on the incidence, clinical implications, and predisposing factors of valve thrombosis in patients who underwent transcatheter aortic valve replacement (TAVR). This study aimed at determining such information through multislice computed tomography (CT). This trial included 460 consecutive patients who underwent TAVR with a balloon-expandable Edwards Sapien XT or Sapien 3 (Edwards Lifesciences,...
The aim of this study was to evaluate if the residual thrombus burden after aspiration thrombectomy may affect the outcome of primary angioplasty in patients with acute coronary syndrome with ST-segment elevation. The most recent studies on aspiration thrombectomy failed to show clinical benefit in patients with ST-segment elevation. This study is based on...
Between 10% and 15% of patients admitted with ST-segment elevation myocardial infarction present concurrent coronary chronic total occlusion (CTO) in a non-infarct-related artery, which is associated with increased morbidity and mortality. The EXPLORE (Evaluating Xience and Left Ventricular Function in Percutaneous Coronary Intervention on Occlusions After ST-Elevation Myocardial Infarction) trial evaluated whether patients admitted...
A comprehensive analyzis of cerebrovascular events in major randomized controlled studies on transcatheter aortic valve replacement (TAVR) has shown some interesting data on both risks and timing of stroke in this setting. The study carried out by Dr. Neal Kleiman, reviewed data on stroke and stroke predictors among 3,687 patients included in the CoreValve...
Data from this large international registry associate endocarditis after a transcatheter aortic valve replacement (TAVR) with high rates of early and late mortality, and might help find predictors identifying patients with the highest risk of developing this rare but dangerous complication. So far, information on endocarditis after TAVR was limited to small populations. In...

Recent investigations and certain randomized trials suggest that the administration of CD34+ stem cells to patients with refractory angina improves exercise tolerance and decreases angina frequency. The following is a phase 3, randomized, double-blind multicenter trial comparing three groups of patients: active treatment through intramyocardial administration of CD34+ stem cells (autologous, purified), standard of care...
Courtesy of Dr. Carlos Fava. Body mass index (BMI) has always played an important role in heart surgery. However, there is little evidence on BMI effects on TAVI. This study included 491 patients, which were divided according to BMI into: low (<20 Kg/m2 ) normal (20-24.9 Kg/m2 ) overweight (25-30 Kg/m2 ) obese...
Original Title: Long-Term Outcome after Carotid Artery Stenting. A Population-Based Matched Cohort Study. Reference: Stroke. 2016 Jul 12. [Epub ahead of print]. In the prevention of stroke, carotid artery stenting (CAS) is far less invasive than endarterectomy, but its long term outcomes remain unclear. This large cohort study compared the long term outcomes of...
Original Title: Predictors of Restenosis Following Carotid Angioplasty and Stenting. Reference: Elena Zapata-Arriaza et al. Stroke. 2016 Jun 21. Epub ahead of print. Restenosis after carotid PCI is associated to an increase of stroke and death risk. The purpose of this study was to determine the risk and predicting factors associated to carotid restenosis...
Original Title: Outcomes With the Use of the Retrograde Approach for Coronary Chronic Total Occlusion Interventions in a Contemporary Multicenter US Registry. Reference: Dimitri Karmpaliotis et al. Circ Cardiovasc Interv. 2016 Jun;9(6). This study evaluated the safety and efficacy of the retrograde technique for chronic total occlusions. Researchers compared retrograde vs. anterograde technique outcomes...
