ABSTRACT
Introduction and objectives: The Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC) presents its annual activity report for 2021. Methods: All Spanish centers with catheterization laboratories were invited to participate. Data were collected online and were analyzed by an external company, together with the members of the ACI-SEC. Results: A total of 121 centers participated (83 public and 38 private). Compared to 2020, both diagnostic coronary angiograms and percutaneous coronary interventions (PCI) increased by 11,4% and 10,3%, respectively. The radial approach was the most used access (92,8%). Primary PCI also increased by 6.2% whereas rescue PCI (1,8%) and facilitated PCI (2,4%) were less frequently conducted. Transcatheter aortic valve implantation was one of the interventions with the most relevant increase. A total of 5720 transcatheter aortic valve implantation procedures were conducted with an increase of 34,9% compared to 2020 (120 per million in 2021 and 89,4 per million in 2020). Other structural interventions like transcatheter mitral or tricuspid repair, left atrial appendage occlusion and patent foramen oval closure also experienced a significant increase. Conclusions: The 2021 registry demonstrates a clear recovery of the activity both in coronary and structural interventions showing a relevant increase compared to 2020, the year of the COVID-19 pandemic.
