Chronic total occlusions (CTOs) account for approximately 15-20% of patients with stable coronary artery disease. This field has seen various advances regarding treatment, leading to an improvement in the success rate of procedures. According to registries and randomized studies, the main indication for percutaneous coronary intervention (PCI) of CTO should be based more on clinical...
Heart failure is strongly associated with malnutrition or poor nutrition, which has been linked to increased mortality during follow-up. We know that mitral regurgitation causes progressive heart failure and affects nutrition. The COAPT Study has demonstrated the benefits of edge-to-edge treatment in mitral regurgitation when combined with comprehensive medical treatment and maximum tolerated doses. However,...
Predictors of intrastent restenosis in the right coronary artery ostium. The ostium of the right coronary artery (RCA) presents certain histological aspects. Atherosclerotic and fibrotic plaques in this area contain an abundance of smooth muscle, collagen, and a certain degree of calcification, along with thicker adventitia. Additionally, it has certain anatomical aspects such as poor...
Among patients undergoing percutaneous coronary intervention (PCI), there is a need for risk stratification for successful planning and post procedural management. Risk stratification is paramount for effective decision making. For a long time, the SYNTAX score has been the preferred tool for complex PCI patient risk assessment. However, it has important limitations, such as inter-observer...
Studies and registries assessing sex differences in chronic total occlusions (CTO) are limited and women are under-represented, accounting for only 14%-21% of included patients. Even though success rate is comparable between sexes, several studies have shown higher complications rate among women. The aim of this study was to identify sex related baseline and procedural differences,...
Safety and efficacy of the ClotTriever device in extended deep vein thrombosis. The endovascular treatment of thromboembolic disease has evolved and new devices have come out in the last few years to reduce morbimortality from its complications. Sub-treating this pathology has long term implications, such as reduced quality of life, limiting functional class and, worst...
The rise of chronic total occlusions (CTO) percutaneous coronary interventions (PCI) goes hand in hand with technological development, through still posing a great challenge, one not exactly exempt from complications. An important criterion to successful CTO PCI is length: ≥20 mm lesions lower the odds, according to J-CTO Score. However, increasing operator experience and the...
Prospective registry of PTE patients who underwent FlowTriever, with 6 months of follow-up. The clinical relevance of interventional treatment in pulmonary thromboembolism (PTE) is often discussed, and no clinical studies have demonstrated a decrease in “hard” outcomes such as mortality. However, in recent years the use of catheter-directed therapies has increased, either through its main indication,...

Event predictors in patients with plaque erosion and no stenting. A third of all acute coronary syndrome (ACS) cases are caused by plaque erosion. In the initial EROSION study, it was shown that patients with plaque erosion (as evidenced by OCT, with stenosis <70%, TIMI III flow, and asymptomatic) were stabilized without stent implantation (no...
