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. ⋯ 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.

Platypnea-orthodeoxia is a peculiar syndrome characterized by a right-to-left shunt, which occurs in the upright position. The diagnosis is made by contrast transesophageal echocardiography, paying attention to include contrast visualization in the orthostatic decubitus. The association of this syndrome with a fenestrated atrial septal aneurysm is rare and probably underlies a peculiar and also rare mechanism of shunting in presence of normal pulmonary pressure. We report of a case of a 58-year-old man with a fenestrated atrial septal aneurysm and platypnea-orthodeoxia syndrome treated by surgical closure of the atrial defect.

Multicenter Study Comparative Study Clinical Trial
One-year clinical experience with the Acorn CorCap cardiac support device: results of a limited market release safety study in Italy and Sweden.
The Acorn CorCap cardiac support device (CSD) is a mesh-like device intended to provide end-diastolic support and reduce ventricular wall stress. Animal studies with the CorCap CSD have demonstrated beneficial reverse remodeling, and preliminary safety studies in patients with heart failure have shown that the device is safe and associated with improved left ventricular (LV) structure and function. The objective of the current study was to further evaluate the safety and efficacy of the CorCap CSD in patients with advanced heart failure. ⋯ In agreement with earlier safety studies, even the present investigation demonstrated improvements in cardiac structure and function as well as in patient functional status after Cor Cap CSD implantation. Randomized controlled trials are in progress.

Comparative Study
Cost of single-vessel and multivessel coronary drug-eluting stenting: comparison to the DRG funding level.
Large-scale utilization of drug-eluting stents (DES) presents significant economic limitations, related to the current high cost of the device and the absence of adequate reimbursement from the health care system. The aim of the study was to evaluate the cost of single-vessel and multivessel drug-eluting stenting and to compare it with the DRG funding level. ⋯ The mean total cost of a single-vessel PCI with DES falls within the DRG 112 reimbursement level for coronary angioplasty of 7006 Euro, while that of multivessel PCI with multiple DES is about 40% above the same reimbursement level. Interestingly, the multivessel PCI cost with multiple DES does fall within the reimbursement amount related to DRG 107 for bypass surgery procedures (14,322 Euro).

Comparative Study
Transcatheter palliation of congenital heart disease with reduced pulmonary blood flow.
Although surgical shunt is still considered as the best palliation of congenital heart disease with reduced pulmonary blood flow, stent implantation may be technically simpler, safer and more cost-effective than surgery in high-risk patients. This study evaluated the feasibility and results of this option in patients with duct-dependent pulmonary blood flow or systemic-to-pulmonary shunt malfunction. ⋯ Stent implantation is a technically feasible, safe and effective palliative option in high-risk surgical patients with congenital heart disease and reduced pulmonary blood flow. Although larger series are required to define the cost-effective clinical impact of this therapeutic option, it is reasonable to hypothesize a further extension of its indication even to elective and low-risk surgical patients.
