Courtesy of Dr. Gustavo Leiva. Coronary Artery Bypass Graft (CABG) has traditionally been the procedure of choice in patients with left main coronary artery disease. However, the use of percutaneous techniques in this kind of lesions has been on the rise, partly due to recent research showing similar outcomes with both procedures. Unprotected left main...
Courtesy of Dr. Carlos Fava. The balloon aortic valvuloplasty (BAV) was introduced by Dr. Cribier in 1986. However, given its poor results, soon after it fell into disuse. With the introduction of TAVR, it saw a revival as bridge for another intervention, even though it is still resisted in many places. The present study...
Patients with symptomatic stenosis of the internal carotid artery benefit from early intervention. The challenge lies in what intervention to choose. Most studies comparing endarterectomy to carotid stenting are fairly heterogeneous as regards timing of intervention. This element is key to comparing between procedures, since there is no doubt timing will directly affect results. ...
Silent ischemic embolic lesions are common after transcatheter aortic valve implantation (TAVI). The use of cerebral protection devices might reduce the occurrence of these embolic lesions. Multiple studies with different devices, designs, and outcomes challenge the usefulness of cerebral protection during TAVI. A comprehensive analysis of the literature was necessary to obtain a more...
Complex vascular anatomy could increase the risk of periprocedural stroke during carotid artery stenting (CAS). However, no randomize study has provided evidence showing this potential difficulty should inform the choice between carotid stenting and endarterectomy. This study included 184 patients with symptomatic lesions of the internal carotid randomized to CAS vs. endarterectomy in the context...
Courtesy of Dr. Carlos Fava. Carotid artery stenting (CAS) has proven to be effective in high-risk patients. Nowadays, when performed by trained operators, its results are similar to those of surgery. This study seeks to clarify the incidence and prognosis of plaque protrusion through the stent (as observed in both control angiography and intravascular ultrasound [IVUS])...
There have been several studies offering contradictory data on the relative effectiveness of carotid artery stenting and carotid artery endarterectomy for the prevention of stroke due to carotid artery stenosis. The authors of this study performed a meta-analysis assessing the efficacy of these techniques, given recently published clinical trial data. They selected randomized...
Courtesy of Dr. Carlos Fava. Transcatheter aortic valve replacement (TAVR) has proven to be beneficial for extreme- and high-risk patients. It is also increasingly used in intermediate-risk patients, and it has been hinted at for low-risk patients. However, different sectors in the medical community still challenge the existence of real TAVR benefit. This assessment consisted...
Courtesy of Dr. Carlos Fava. Carotid artery disease is an important cause of stroke and is associated to coronary artery disease. When patients need myocardial revascularization surgery (Carotid Artery Bypass Graft) and cannot wait one month or more for carotid revascularization, the optimal management strategy is still controversial. The aim of this study was...
Cerebral embolic protection is a strategy to prevent embolization of thrombotic or calcific debris during transcatheter aortic valve replacement (TAVR). A number of randomized and controlled studies have tested the safety and efficacy of various devices, though none of them have enough statistical power to show significant differences in end points. While preliminary...
