Luminal thrombotic occlusions associated with non-significant atherosclerosis are commonly observed in patients with critical lower limb ischemia, which suggests the possibility of thromboembolic disease as a great contributor to ischemia. This was particularly verifiable in infrapopliteal vessels, thus showing a possible mechanism of progression from peripheral vascular disease to critical ischemia, as well as a…
Differences in Stroke between TAVR and SAVR in Intermediate Risk Patients
Transcatheter aortic valve replacement (TAVR) is more and more frequent in lower risk populations that had previously been treated with surgical valve replacement (SAVR). A small difference in neurological events could have significant consequences when it comes to deciding a course of action. This study is a sub-analysis of the randomized study SURTAVI (Surgical Replacement…
New Anticoagulant Agents in Atrial Fibrillation in Latin American Patients, Specifically
There is limited information on the use of antithrombotic therapies and their outcomes in Latin American patients with atrial fibrillation. This stands true in almost all aspects of medicine: large multicenter randomized studies rarely include Latin American countries, and when they do, the population included is not representative of the overall population. The only exception…
Safety of Early Carotid Artery Stenting in Symptomatic Patients
This work shows the safety of carotid artery stenting within 14 days of a stroke and, so far, this is the largest series of symptomatic patients published by an institution. The exact moment to conduct this procedure after an acute stroke is still controversial, although most publications so far have favored early endarterectomy over early angioplasty.…
Debris Captured by SENTINEL Devices Result Different across Different Valves
The idea behind this study is that debris can be captured in all patients during TAVR, even though we still ignore which patients would benefit more from this device. Tissue particles captured by the SENTINEL during TAVR vary from valve to valve, according to this new analysis. There are differences in size and number of…
Stroke Rate after CABG vs PCI in over 10,000 Patients
Repeat revascularization rate has historically been the weak spot of PCI when compared against CABG: we are still unable to compete with a well done internal mammary artery graft connected to the anterior descending artery. However, repeat revascularization is the soft of end points commonly assessed in trials, and even though several studies have shown…
How to Predict Events in Order to Decide Whether to Revascularize Symptomatic Carotid Artery Stenosis
Current models are not reliable when it comes to predicting events after carotid revascularization in acute patients. Peri-procedural events seem to be particularly hard to predict. The development of models that can be externally validated is essential for the decision-making process in patients with high event rates, both during the procedure or while the case…
Post Carotid Stenting Cerebral Hyperperfusion: a Preventable Complication
This syndrome, which can be reverted, is also one of the causes of preventable stroke, at least in the context of carotid endarterectomy. At present, there is little information on the incidence of this condition in the context of carotid stenting, which is the purpose of this study, in addition to providing tips to prevent it.…
Differences in Debris Captured According to Valve Type
During valve replacement, cerebral protection systems may capture debris in up to 99% of all patients. In over half of them, these particles are >1 mm. The particles captured during procedures in which Evolut R or Lotus valves were used were more and larger compared with those captured with the Sapien balloon-expandable valve. Beyond differences among valves,…
DEFENSE-PFO: High Risk PFO Closure Reduces Combined Events and Stroke Risk
High risk patent foramen ovale closure PFO resulted in reduced stroke, vascular death and bleeding risk. Recent reports have shown a favorable role of PFO in patients with cryptogenic stroke, though with some unclear results, which immediately raised the questions: Who are the optimal candidates for this procedure, and who will see no benefit? …
