Background: The Pacemaker (PM) and Implantable Cardioverter-Defibrillator (ICD) Registry of the Italian Association of Arrhythmology and Cardiac Pacing (AIAC) collects information about demographics, clinical characteristics, main indications for PM/ICD therapy and device types from the voluntary Italian collaborating centers. Methods: For the year 2021 main data about national PM and ICD implantation activity were obtained on the basis of European Cards and subsequently analyzed to create a standard report. Results: PM Registry: data about 18 631 PM implantations were collected (15879 first implants and 2752 replacements). The number of collaborating centers was 121. Median age of treated patients was 82 years (76 quartile I; 87 quartile III). Main ECG indications included atrioventricular conduction disorders in 26.8% of first PM implants, sick sinus syndrome in 12.2%, atrial fibrillation plus bradycardia in 9.6%, other unspecified ECG and electrophysiological abnormalities in 43.0%. For first PM implants, pacing in DDDR mode was reported in 46.5%, followed by DDD mode (20.6%), VVIR mode (15.0%), VVI mode (9.0%) and finally VDD-VDDR (5.8%). Median value of longevity of explanted PMs was 8.9 years. ICD Registry: data about 6878 ICD implantations were obtained (4708 first implants and 2170 replacements). The number of collaborating centers was 345. Median age of treated patients was 72 years (70 quartile I; 75 quartile III). Primary prevention indication was reported in 86.3% of first implants, secondary prevention in 13.7% (cardiac arrest in 4.4% of records). A single-chamber ICD was used in 32.1% of first implants, dual-chamber ICD in 30.3% and biventricular ICD in 37.6%. Median value of longevity of explanted ICDs was 6.9 years. Conclusions: In the calendar year 2021, the Italian PM Registry showed stable electrocardiographic and symptom indications, with an important prevalence of dual-chamber pacing. The ICD Registry documented a large use of prophylactic and biventricular ICDs, reflecting a favorable adherence in the clinical practice to trials and guidelines. The ICD longevity and the number of recalls demonstrated a favorable trend. In order to increase and optimize the cooperation of Italian PM and ICD implanting centers, the online data entry (https://www.aiac.it/riprid) should be adopted at large scale.

Abstract

Background: The Pacemaker (PM) and Implantable Cardioverter-Defibrillator (ICD) Registry of the Italian Association of Arrhythmology and Cardiac Pacing (AIAC) collects information about demographics, clinical characteristics, main indications for PM/ICD therapy and device types from the voluntary Italian collaborating centers. Methods: For the year 2021 main data about national PM and ICD implantation activity were obtained on the basis of European Cards and subsequently analyzed to create a standard report. Results: PM Registry: data about 18 631 PM implantations were collected (15879 first implants and 2752 replacements). The number of collaborating centers was 121. Median age of treated patients was 82 years (76 quartile I; 87 quartile III). Main ECG indications included atrioventricular conduction disorders in 26.8% of first PM implants, sick sinus syndrome in 12.2%, atrial fibrillation plus bradycardia in 9.6%, other unspecified ECG and electrophysiological abnormalities in 43.0%. For first PM implants, pacing in DDDR mode was reported in 46.5%, followed by DDD mode (20.6%), VVIR mode (15.0%), VVI mode (9.0%) and finally VDD-VDDR (5.8%). Median value of longevity of explanted PMs was 8.9 years. ICD Registry: data about 6878 ICD implantations were obtained (4708 first implants and 2170 replacements). The number of collaborating centers was 345. Median age of treated patients was 72 years (70 quartile I; 75 quartile III).
