Article Synopsis
- This article reports on the annual activities of the Interventional Cardiology Association of the Spanish Society of Cardiology for 2022.
- A total of 111 centers participated, revealing a 4.8% increase in diagnostic studies and a significant 22% rise in PCIs on the left main coronary artery, while the overall PCI numbers remained stable.
- Key trends included a preference for the radial approach in 94.9% of cases, increased use of drug-eluting balloons and intracoronary imaging, and a continuous rise in noncoronary procedures, especially those related to heart valve and structural heart issues.

Article Synopsis
- This study investigates the agreement between fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) in patients with intermediate stenosis in the left main coronary artery (LMCA), finding an 80% concordance between the two methods.
- The research involved 300 patients and emphasized the role of intravascular ultrasound (IVUS) for assessing cases where FFR and iFR results disagreed, identifying minimal lumen areas as a factor in decision-making.
- Over a 20-month follow-up, deferral of revascularization based on iFR and IVUS showed a lower incidence of major adverse cardiac events compared to those who underwent revascularization, suggesting that deferring treatment
Article Synopsis
- Paravalvular leaks (PVL) occur in 5-17% of patients after surgical valve replacement, especially in the mitral position, and if untreated, can lead to poor outcomes.
- This study assessed the effectiveness and safety of percutaneous closure for mitral PVLs over a median follow-up of about 42 months, analyzing 128 procedures from 2010 to 2020.
- Results showed a high success rate (89.8%) for the procedure, with significant improvements in patient outcomes and long-term survival, especially for those without complications like chronic kidney disease.

Article Synopsis
- The study aimed to evaluate the outcomes of elderly patients (over 75 years) undergoing percutaneous transluminal coronary intervention (PCI) using an antithrombotic strategy that considers their individual risks for bleeding and ischemic events.
- The research included 1,064 patients and found that the incidence of major adverse cardiovascular events and bleeding was lower in this tailored treatment group compared to a control group, with no cases of stent thrombosis in those receiving shorter dual antiplatelet therapy.
- The conclusion indicates that a risk-adjusted antithrombotic protocol for elderly patients after revascularization with the latest stent technology may lead to better health outcomes regarding both bleeding and ischemic events.
Data regarding angiographic characteristics, clinical profile, and inhospital outcomes of patients with coronavirus disease 2019 (COVID-19) referred for coronary angiography (CAG) are scarce. This is an observational study analyzing confirmed patients with COVID-19 referred for CAG from 10 European centers. We included 57 patients (mean age: 66 ± 15 years, 82% male) , of whom 18% had previous myocardial infarction (MI) and 29% had renal insufficiency and chronic pulmonary disease.
