PCI success rate in chronic total occlusion (CTO), according to some registries, is below 80%. These failed revascularization procedures might lead to quality-of-life deterioration and shorter survival. This concern has driven the development of new techniques and technologies in an attempt to increase PCI success. Today, approximately 20% of CTOs are treated with a second…
Transfemoral vs Transradial Approach in the Percutaneous Treatment of CTO
Percutaneous treatment of chronic total occlusion (CTO) has traditionally been via the transfemoral approach (TFA). The use of the transradial approach (TRA) in complex coronary interventions has been increasing. A randomized study assessed the use of TRA vs TFA in complex PCI (58% CTO) and TRA saw favorable outcomes. The aim of this prospective, randomized,…
In-Hospital Costs and Costs of Complications of Chronic Total Occlusions
Is a chronic total occlusion worth rechanneling? This question can often be found in different studies, all of them with clinical endpoints. This study (soon to be published in J Am Coll Cardiol Intv.) analyzes another aspect: costs, not only derived from materials used for a successful procedure, but also from materials and hospital stay…
Success in CTOs caused by restenosis lowers cardiac mortality
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…
EuroCTO: Rechanneling vs. Optimal Medical Treatment in Total Occlusions
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…
PRISON IV: DES with resorbable polymer vs. DES with permanent polymer in total occlusions
Courtesy of SBHCI. The PRISON IV trial compared the sirolimus eluting stent with ultra-thin struts and biodegradable polymer vs. the second-generation everolimus-eluting stent with thin struts and durable polymer in successfully recanalized chronic total occlusions. This is a sub-study with optical coherence tomography (OCT). The study included 330 patients, 85% angiographically followed up at…
Successful CTO: associated to higher survival rate?
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…
Retrograde Technique: High Success Rate in CTO
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…
