    Abstract:
    BACKGROUND: The pacemaker (PM) and implantable cardioverter-defibrillator (ICD) Registry of the Italian Association of Arrhythmology and Cardiac Pacing (AIAC) monitors the main epidemiological data in real-world practice. The survey for the 2019 activity collects information about demographics, clinical characteristics, main indications for PM/ICD therapy and device types from the Italian collaborating centers. METHODS: The Registry collects prospectively national PM and ICD implantation activity on the basis of European cards. RESULTS: PM Registry: data about 22 889 PM implantations were collected (19 621 first implants and 3268 replacements). The number of collaborating centers was 173. Median age of treated patients was 81 years (75 quartile I; 87 quartile III). ECG indications included atrioventricular conduction disorders in 33.3% of first PM implants, sick sinus syndrome in 16.4%, atrial fibrillation plus bradycardia in 11.6%, other in 38.7%. Among atrioventricular conduction defects, third-degree atrioventricular block was the most common type (18.3% of first implants). Use of single-chamber PMs was reported in 25.5% of first implants, of dual-chamber PMs in 67.1%, of PMs with cardiac resynchronization therapy (CRT) in 1.5%, and of single lead atrial-synchronized ventricular stimulation (VDD/R PMs) in 5.8%. ICD Registry: data about 17 328 ICD implantations were collected (12 129 first implants and 5199 replacements). The number of collaborating centers was 425. Median age of treated patients was 71 years (62 quartile I; 77 quartile III). Primary prevention indication was reported in 83.1% of first implants, secondary prevention in 16.9% (cardiac arrest in 5.9%). A single-chamber ICD was used in 26.1% of first implants, dual-chamber ICD in 28.0% and biventricular ICD in 45.9%. CONCLUSIONS: The PM and ICD Registry appears fundamental for monitoring PM and ICD utilization on a large national scale with rigorous examination of demographics and clinical indications. The PM Registry showed stable electrocardiographic and symptom indications, with an important prevalence of dual-chamber pacing. The use of CRT-PM regards a very limited number of patients. The ICD Registry documented a large use of prophylactic and biventricular ICD, reflecting a favorable adherence to trials and guidelines in clinical practice. In order to increase and optimize the cooperation of Italian implanting centers, online data entry (https://www.aiac.it/riprid) should be adopted at large scale.
