SOUHRNTermínem otevřená tepenná dučej (patent ductus arteriosus, PDA) se označuje trvalé spojení mezi sestupnou hrudní aortou a plicnicí, které vzniká, pokud ve fetálním období nedojde k normálnímu fyziologickému uzavření dučeje. Jedná se o poměrně častou vrozenou srdeční vadu. Hlavní metodou léčby je uzavření PDA, které lze provést buď chirurgicky, nebo perkutánně. V posledních 20 letech se prokázala účinnost i bezpečnost katetrizačního postupu; pro tento účel byla vyvinuta řada zařízení, která jsou dnes k dispozici. Tento článek přináší popis katetrizačního uzavření PDA u 18leté pacientky s příznaky připomínajícími velkou PDA. I když jsme původně uvažovali o uzavření PDA Amplatzovým okluderem, nakonec jsme se rozhodli pro použití Amplatzova septálního okluderu (ventricular septal defect [VSD] Amplatzer occluder).ABSTRACT Patent ductus arteriosus (PDA) is a persistent communication between the descending thoracic aorta and the pulmonary artery that results from failure of normal physiologic closure of the fetal ductus. It is one of the more common congenital heart defects. The PDA closure is the main treatment and can be surgical or percutaneous. The trancatheter approach proved its effi cacy and safety all over the past 20 years and a variety of devices have been developed and are now available. This report describes a transcatheter closure of a PDA on an 18-year-old girl with features suggestive of a large PDA. While we intended to close the PDA using an Amplatzer device occluder (ADO), we changed our approach and used a ventricular septal defect (VSD) Amplatzer occluder instead.

Introduction Pulmonary artery aneurysms are a rare entity. Etiologies of these findings are multiple, but they are exceptionally associated with Fallot's Tetralogy. In this study, we present an unusual case of an important aneurysm of the left pulmonary artery associated with Fallot's Tetralogy disease. Case Presentation A 30-year-old woman has been admitted for dyspnea and cyanosis. The data which had been obtained from echocardiography, cardiac catheterization, and angio-magnetic resonance imaging (MRI) suggested the existence of an important aneurysm of the left pulmonary artery associated with a regular Fallot's disease with a pulmonic stenosis. We have noticed the presence of a small restrictive patent ductus arteriosus (PDA). Therefore, the patient was referred to surgical correction. Conclusion Pulmonary artery aneurysms associated with Fallot's Tetralogy are rarely reported. The natural history of these rare arterial aneurysms has to be clarified.
