    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 2015 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 24 285 PM implantations were collected (19 194 first implant and 5091 replacements). The number of collaborating centers was 218. Median age of treated patients was 81 years (75 quartile I; 86 quartile III). ECG indications included atrioventricular conduction disorders in 42.8% of first PM implants, sick sinus syndrome in 22.9%, atrial fibrillation plus bradycardia in 15.1%, other in 19.2%. Among atrioventricular conduction defects, third-degree atrioventricular block was the most common type (23.8% of first implants). Use of single-chamber PMs was reported in 26.9% of first implants, of dual-chamber PMs in 63.4%, of PMs with cardiac resynchronization therapy (CRT) in 1.8%, and of single lead atrial-synchronized ventricular stimulation (VDD/R PMs) in 7.9%. ICD Registry: data about 15 363 ICD implantations were collected (11 453 first implants and 3910 replacements). The number of collaborating centers was 434. Median age of treated patients was 71 years (63 quartile I; 78 quartile III]. Primary prevention indication was reported in 77.3% of first implants, secondary prevention in 22.7% (cardiac arrest in 8.0%). A single-chamber ICD was used in 29.3% of first implants, dual-chamber in 34.6% and biventricular in 36.1%. 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.
