Courtesy of Dr. Carlos Fava. The presence of Chronic Total Occlusion (CTO) is about 30%, with an ischemic threshold between 10% and 12.5% to justify rechannelization. Using the new devices, the new guidelines and with more experience operators, these procedures are successful in 10% to 30% of cases. More often than not these patients are not treated...
An international event addressed to experts in chronic total occlusions will be held the next 15 and 16 of September. The CTO Summit Brazil II 2017 will take place in San Pablo, and will give special emphasis to the current diverse techniques in the treatment of CTO and is practical aspects. The meeting, organized by the...
Courtesy of Dr. Carlos Fava. It has been proved that in a setting of acute myocardial infarction with multivessel lesions, only the culprit vessel must be treated (if there is no hemodynamic compromise) at first, and other severe lesions are to be treated during a second session. However, proper conduct in cases with presence of chronic...
Courtesy of Dr. Carlos Fava. Nowadays, chronic total occlusions (CTO) due to in-stent restenosis (ISR) represent 5%-25% of all coronary angioplasties. These lesions pose a new and true challenge, since CTOs are often associated with stent-related problems (fractures, lack of expansion, overlapping, deformation), extreme tortuosity, severe calcification, tandem lesions after CTO, and aorto-ostial lesions, with little...
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. ...
Courtesy of the SBHCI. Chronic total occlusions represent around 18% of all coronary lesions. However, they account for just 5% of all interventions, which means that many patients only receive medical treatment. This prospective, open, multicenter study randomized patients with multivessel lesions in whom at least one of these was a chronic total occlusion. Patients...
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. The presence of chronic total occlusions (CTO) in coronary angiograms varies between 5% and 30%, depending of the different analyzis. Likewise, they have been associated to higher mortality rate and the need for myocardial revascularization surgery. The frequency of CTO PCI is low across the different series (3.8%), though...
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. Chronic Total Occlusions (CTO) are truly challenging and different technologies are being developed to treat them, but currently our most pressing questions about them are whether in-stent CTO present the same success rate as de novo CTO, and what their prognosis is. The present trial analyzed 899 CTO: 111(12.3%)...
