Coronary sinus reduction (CSR) is a relevant area of study for the treatment of refractory angina, with hopes of improving myocardial perfusion. However, to date, there are no conclusive data. The ORBITA-COSMIC study is a randomized, double-blind, placebo-controlled trial conducted at six centers in the UK. Researchers recruited patients with angina and chronic ischemia who...
The use of intravascular imaging to identify vulnerable plaque (VP) has proven to be very useful, as such plaque is associated with an increase in major adverse cardiac events. Optimal medical treatment is currently considered the standard strategy to stabilize VP. However, the safety and effectiveness of preventive treatment with percutaneous coronary intervention (PCI) in...
The international guidelines recommend the use of dual antiplatelet therapy (DAPT) with aspirin plus a P2Y12 inhibitor during 12 months in patients receiving percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS), to prevent events such as MI and stent thrombosis. This was a multicenter, placebo controlled, double blind study to determine whether ticagrelor alone,...
Assessing intermediate coronary lesions with intracoronary physiology tests such as fractional flow reserve (FFR) or other non-hyperemic indices is considered the standard of care by both American and European societies. Likewise, intravascular imaging techniques (IVI), be it IVUS or optical coherence tomography (OCT), are of great use in assessing and guiding complex coronary lesions and...
Chronic total occlusions (CTO) occur in up to 20% of patients undergoing diagnostic angiographic studies. Over the past two decades, the optimization of recanalization techniques, the development of new specialized devices, and improvement in operator skill have contributed to an increased procedural success rate, reaching 90%. However, specific complications such as collateral perforation and access...
Proximal optimization technique (POT) has been recommended as a standard strategy in bifurcation lesions because it facilitates proper stent implantation and apposition in the proximal main vessel, according to the European Bifurcation Club. Percutaneous coronary intervention (PCI) of the unprotected left main coronary artery (LMCA) has specific characteristics, and the long-term impact of this strategy...
Severe aortic stenosis due to a bicuspid aortic valve (BAV) is uncommon, especially in individuals under 65 years of age. While there are usually no significant differences according to the type of valve when it comes to surgery, with transcatheter aortic valve replacement (TAVR) some may arise. TAVR has seen significant advancements in the treatment...
TAVR has been shown beneficial, especially in high risk or inoperable patients. However, there are limitations to its use, especially with self-expanding valves, which are the need for pacemaker implantation and ECG changes after procedure. To address this matter, researchers assessed the right and left cusp overlap effect on 254 patients undergoing TAVR with self-expanding...
The retrograde approach for recanalizing chronic total occlusions (CTO) has undergone significant evolution since its introduction in 1990, improving both in terms of techniques and specialized materials. The increased skill applied to this strategy has resulted in increased success rates for the treatment of CTO in sites with an adequate volume of procedures. Given the...
The XLVII SOLACI Regional Sessions – 16th Andean Region took place in Lima, Peru, between November 16 and 17, 2023.It was an extremely successful event that featured the participation of prestigious national and international guests and a high-level scientific program. Below, we share some of the presentations that were made during the Sessions. Dra. Carla...
