Introduction and Objectives: This article presents the 2023 activity report of the Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC)., Methods: All interventional cardiology laboratories in Spain were invited to participate in an online survey. Data analysis was carried out by an external company and subsequently reviewed and presented by the members of the ACI-SEC board., Results: A total of 119 hospitals participated. The number of diagnostic studies decreased by 1.8%, while the number of percutaneous coronary interventions (PCI) showed a slight increase. There was a reduction in the number of stents used and an increase in the use of drug-coated balloons. The use of intracoronary diagnostic techniques remained stable. For the first time, data on PCI guided by intracoronary imaging was reported, showing a 10% usage rate in Spain. Techniques for plaque modification continued to grow. Primary PCI increased, becoming the predominant treatment for myocardial infarction (97%). Noncoronary structural procedures continued their upward trend. Notably, the number of left atrial appendage closures, patent foramen ovale closures, and tricuspid valve interventions grew in 2023. There was also a significant increase in interventions for acute pulmonary embolism., Conclusions: The 2023 Spanish cardiac catheterization and coronary intervention registry indicates a stabilization in coronary interventions, together with an increase in complexity. There was consistent growth in procedures for both valvular and nonvalvular structural heart diseases., (Copyright © 2024 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U.

Background: Paravalvular leak occurs in 5-17% of patients following surgical valve replacement, more often in mitral position. The prognosis without treatment is poor. Percutaneous device closure represents an alternative to repeat surgery. The objective of this work is to evaluate the medium and long-term results in the percutaneous closure of PVL in mitral prosthesis., Methods: This observational study is based on a retrospective registry including consecutive mitral PVL cases undergoing percutaneous closure at a single tertiary-care center from April 2010 to December 2020. The safety and efficacy results of the procedure, at 90 days and in the long term, were analyzed. Also, predictors of procedure failure and long-term events were identified., Results: A total of 128 consecutive mitral paravalvular leak closure procedures were included. Technical success was achieved in 115 (89.8%) procedures. The presence of multiple PVLs was the sole factor that independently predicted procedural failure. Median follow-up of our sample was 41.8 months (mean 47.7 ± 35.7 months). Underlying hemolytic anemia as the indication for PVL closure, a recent admission for decompensated HF, and lack of improvement in functional class emerged as consistent predictors of MACE and death during long-term follow-up, while lack of procedural success during the first PVL procedure and chronic kidney disease were also associated with MACE during follow-up., Conclusions: Percutaneous mitral PVL closure displayed high technical and procedural success rates, with an acceptable safety profile, in a high-risk population. Percutaneous mitral PVL closure achieved an improvement in short- and long-term functional class and a reduction of hemolysis in the vast majority of patients. In addition, long-term survival in our study was good, in particular for patients undergoing successful PVL closure procedures.
