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.

Introduction and Objectives: This article presents the annual activity report of the Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC) for the year 2022., Methods: All Spanish centers with catheterization laboratories were invited to participate. Data were collected online and were analyzed by an external company in collaboration with the members of the board of the ACI-SEC., Results: A total of 111 centers participated. The number of diagnostic studies increased by 4.8% compared with 2021, while that of percutaneous coronary interventions (PCI) remained stable. PCIs on the left main coronary artery increased by 22%. The radial approach continued to be preferred for PCI (94.9%). There was an upsurge in the use of drug-eluting balloons, as well as in intracoronary imaging techniques, which were used in 14.7% of PCIs. The use of pressure wires also increased (6.3% vs 2021) as did plaque modification techniques. Primary PCI continued to grow and was the most frequent treatment (97%) in ST-segment elevation myocardial infarction. Most noncoronary procedures maintained their upward trend, particularly percutaneous aortic valve implantation, atrial appendage closure, mitral/tricuspid edge-to-edge therapy, renal denervation, and percutaneous treatment of pulmonary arterial disease., Conclusions: The Spanish cardiac catheterization and coronary intervention registry for 2022 reveals a rise in the complexity of coronary disease, along with a notable growth in procedures for valvular and nonvalvular structural heart disease., (Copyright © 2023 Sociedad Española de Cardiología.

Introduction and Objectives: Thyroid hormone affects the metabolism of all tissues in the body. The aim of this study was to analyze the prevalence and implications of thyroid disorders in a cohort of consecutive patients with spontaneous coronary artery dissection (SCAD)., Methods: A total of 73 patients with SCAD were analyzed. Baseline characteristics and clinical outcomes were compared between euthyroid and hypothyroid patients. Subsequently, the prevalence of thyroid function abnormalities and the clinical characteristics of SCAD patients were compared with those in 73 patients with acute coronary syndrome but without SCAD, matched by age, sex, and presentation., Results: Mean age was 55 ± 12 years and 26% had hypothyroidism. Compared with patients with normal thyroid function, patients with SCAD and hypothyroidism were all women (100% vs 69%, P = .01), more frequently had dissection in distal (74% vs 41%, P = .03) and tortuous coronary segments (68% vs 41%, p = .03), and more frequently received conservative medical management (79% vs 41%, P = .007). During a mean clinical follow-up of 4.1 ± 3.8 years, 23% of the patients had adverse cardiac events irrespective of thyroid function status. The prevalence of hypothyroidism was higher in patients with SCAD than in matched patients with acute coronary syndrome without SCAD (26% vs 8%, P = .004)., Conclusions: There is a high prevalence of hypothyroidism in patients with SCAD. Patients with SCAD and hypothyroidism are more frequently women, more frequently have distal dissections in tortuous vessels, and are more frequently managed with a conservative medical strategy., (Copyright © 2018 Sociedad Española de Cardiología.

Introduction and Objectives: Coronary angiography is the gold standard for the study of coronary artery disease. This technique requires several orthogonal projections. Rotational angiography is a new technique which involves pre-set rotation of the X-ray tube around the patient and allows visualization of each coronary artery in different views, using a single contrast injection. The purpose of this study was to compare conventional coronary angiography (A) vs rotational angiography (B), focusing on radiation dose, amount of contrast administered, and total procedure time for both diagnostic and therapeutic percutaneous coronary interventions., Methods: Prospective study of 104 consecutive patients undergoing coronary angiography who were randomized to one of these techniques., Results: We found a significant reduction in the amount of contrast administered (A vs B, 93.1 [41.7] vs 50.9 [14.7] mL; P<.0001) and radiation exposure (27.6 [11.5] vs 18 [6.4] mGycm(2); P<.0001). A significant increase in total procedure time was noted in the rotational angiography arm. However, when only the last 50 patients were analyzed, we found no difference in procedure time between the groups, probably related to the learning curve of the operators. Angioplasty was performed in 29 patients in group A and 28 patients in group B. Contrast reduction was maintained in the rotational angiography group compared to the conventional technique (A vs B, 335.1 [192.1] vs 238.5 [114.4] mL; P=.02)., Conclusions: The rotational angiography technique leads to a significant decrease in radiation exposure and contrast dose administered for diagnostic procedures when compared to conventional coronary angiography. In patients who undergo percutaneous coronary intervention, contrast reduction remains significant., (Copyright © 2011 Sociedad Española de Cardiología. Published by Elsevier Espana.
