Pancreas sparing duodenectomy and aortic reconstruction with custom-made bovine pericardial tubular graft for primary aorto duodenal fistula. Case report.

Primary aorto-duodenal fistula (PADF) is a rare life-threatening condition consisting in a direct communication between the abdominal aorta and the gastrointestinal tract without any previous vascular intervention. PADF results most commonly from an abdominal aortic aneurism (AAA) or aortic bacterial/mycotic infection, with the fistula forming between the native aorta and the third or fourth portion of the duodenum. Symptoms are nonspecific and the diagnosis is often delayed after AAA rupture with high rate of morbidity and mortality.

Clinical outcome of patients with de novo coronary bifurcation lesions treated with the Tryton Side Branch Stent. The SAFE-TRY prospective multicenter single arm study.

Background: Coronary bifurcation lesions represent a difficult problem regularly confronting interventional cardiologist, in part due to the lack of dedicated device.

Objective: To investigate the feasibility, safety and effectiveness of the Tryton Side Branch Stent (Tryton Medical, Durham, NC, USA), a dedicated bare metal stent deployed in conjunction with a standard drug-eluting stent to treat bifurcation lesions.

Methods: The SAFE-TRY is a prospective single arm multicenter registry including patients with de novo bifurcation lesions in native coronary arteries and syntax score <32.

Anatomical and electrophysiological approach to atrial fibrillation ablation: technical limitations.

Objective: Pulmonary vein (PV) disconnection by radiofrequency (RF) catheter ablation has been reported to cure atrial fibrillation (AF). Different techniques have been proposed. The aim of this study was to evaluate the technical limitations of both anatomical and electrophysiological approaches.
