The Italian Implantable Cardioverter-Defibrillator Registry. A survey of the national activity during the years 2001-2003
No full textBACKGROUND:
In recent years several trials demonstrated the efficacy of implantable cardioverter-defibrillator (ICD) therapy for sudden cardiac death prevention and total mortality reduction in particular high-risk groups of patients. The aim of this review was to report the main epidemiological data and the most important clinical characteristics of patients enrolled in the Italian ICD Registry in the years 2001-2003.
METHODS:
The Italian ICD Registry--official member of the Italian Association of Arrhythmology and Cardiac Pacing (AIAC)--collects 85% of the data concerning the national ICD implantation activity, based on the European Implantable Defibrillator form (EURID). Data are validated for quality of information and uniqueness at the moment of data entry and in successive steps at the time of the annual analysis.
RESULTS:
The number of ICDs implanted in Italy has been continuing to increase during the last years according to the general trend in European and non-European countries: 2400 in the year 2001, 3934 in the year 2002, and 5318 in the year 2003. The number of ICDs per million of inhabitants in Italy was 42.1 in the year 2001 (+11.8% with respect to 2000), 69.0 in the year 2002 (+63.9% with respect to 2001), and 93.3 in the year 2003 (+35.2% with respect to 2002). The number of implanting centers increased progressively from 273 in the year 2001 to 304 in the year 2002, and 340 in the year 2003. The median age of patients treated with ICD implantation was 67 years in the years 2001-2002, 68 years in the year 2003. The prevalence of male patients was significantly higher (79.3% in 2001, 82.3% in 2002, and 81.4% in 2003). The main indication was syncope (25.5, 29.3, and 32.9% in the years 2001, 2002, and 2003, respectively), followed by palpitations (17.7, 18.5, and 16.4% in the years 2001, 2002, and 2003, respectively), and cardiac arrest (10.0, 13.1, and 16.5% in the years 2001, 2002, and 2003, respectively). The use of ICD in patients considered at risk but without history of sustained ventricular tachycardia had a 3-fold increase during the 3 years, from 6.4% in 2001 to 18.2% in 2003. Ventricular tachycardia was the main arrhythmia in 50.4 to 55.0% of cases, ventricular fibrillation in 13.5 to 18.1%, both in 4.1 to 6.5%. The vast majority of patients presented at the enrolment either a mild or severe reduction in ejection fraction (30 to 50%, < 30%). Amiodarone was administered alone or in combination with antiarrhythmics in 29.7 to 40.0% of patients. Single-chamber ICDs were implanted in the years 2002 and 2003 in 45.7 and 39.2% of patients, dual-chamber ICDs in 34.9 and 32.4%, biventricular ICDs in 19.4 and 28.4%, respectively.
CONCLUSIONS:
The ICD implantation rate in Italy increased significantly in the period 2001-2003, similarly to the trend in the other western countries and following the publication of controlled studies in the field of primary and secondary prevention of sudden cardiac death. The Italian ICD Registry showed during the last 3 years an important increase in prophylactic ICD utilization. A sophisticated ICD, including dual-chamber pacing or cardiac resynchronization therapy, was chosen in a high percentage of patients
Impact of the main implantable cardioverter-defibrillator trials for primary and secondary prevention in Italy: A survey of the national activity during the years 2001-2004
No full textBackground: Several trials demonstrated the lifesaving role of implantable cardioverter-defibrillator (ICD) in high-risk groups of patients. Aim of this review was to report the clinical characteristics of patients enrolled in the ICD Registry of the Italian Association of Arrhythmology (AIAC) in the years 2001-2004. Methods: The Registry collects prospectively 85% of national ICD implantation activity on the basis of European ICD form (EURID). Results: The number of implanted ICDs in Italy was 2,418 in the year 2001, 3,992 in the year 2002, 5,595 in the year 2003, and 7,190 in the year 2004. The number of ICDs per million of inhabitants was 42.1 in the year 2001 (+11.8% respect to 2000), 70.0 in the year 2002 (+65.1% respect to 2001), 98.3 in the year 2003 (+40.4% respect to 2002), and 125.0 in the year 2004 (+27.2% respect to 2003). The median age was 67 years in the years 2001-2002, 68 years in the years 2003-2004. The main indications during the study were syncope (24.2-14.9%) and ..

No full textWe report the case of a patient who underwent Cabrol composite graft procedure for ascending aorta aneurysm and aortic regurgitation. Sixteen years later he developed progressive dyspnea and a left-to-right shunt caused by distal detachment of the valve conduit with persistence of the perigraft space-right atrial fistula visualized with echocardiography. Our case shows that late manifestations of surgical complications of the Cabrol procedure may occur and transesophageal echocardiography may allow a comprehensive assessment in these patients. However, because surgical management of ascending aorta aneurysms has changed in the last decades a detailed knowledge of the surgical technique used is mandatory for adequate interpretation of transesophageal echocardiographic result
