profound bradycardia following patent ductus arteriosus closure; a rare but correctable event

Profound Bradycardia following Patent Ductus Arteriosus Closure; A Rare but Correctable Event.

Proximity of the vagus nerve to  a patent  ductus  arteriosus (PDA) can cause traction  or  entrapment  of vagus nerve during surgical closure of the in rare occasions. This can lead to a life threatening postoperative bradycardia. Herein, we report a case of bradycardia caused by unexpected irritation of the vagal trunk by the end of operation. The patient was managed by re-opening the chest, ...

Intravenous Paracetamol and Patent Ductus Arteriosus Closure

Background: Standard medical treatments for patent ductus arteriosus (PDA) closure are, including indomethacin/ibuprofen and surgical ligation. Nowadays, a new strategy to close PDA is the use of paracetamol. The present study aimed to describe the use of intravenous (IV) paracetamol for PDA closure in neonates who present a contraindication to ibuprofen or ibuprofen failure with no possibility...

Closure of Small Patent Ductus Arteriosus by Occluding Detachable Coil

Transfemoral plug closure of patent ductus arteriosus.

A patent ductus arteriosus should be closed because of its hemodynamic significance and/or the risk of infective endocarditis. Mortality of surgery is low. In adults, however, technical problems can arise due to calcification of the ductus walls. Using the transfemoral plug technique, developed by Porstmann, we attempted a ductus closure without surgery on 35 patients. The youngest was an 11-ye...

Transcatheter Closure of Patent Ductus Arteriosus

Background The USCI PDA Umbrella is a device to close patent ductus arteriosus (PDA) by a transcatheter technique. Human clinical trials have shown excellent efficacy in reducing or eliminating the PDA shunt, but concerns remain about the risk of infection with this device. The purpose of this study was to evaluate the risk of infection using an animal model. Methods and Results Susceptibility ...

Transcatheter Closure of Patent Ductus Arteriosus

Patent ductus arteriosus (PDA) constitutes 6 to 11% of all congenital heart defects. While surgical ligation and video-assisted, thoracoscopic interruption of PDA are still available, transcatheter occlusion of PDAs has recently assumed a major role in closure of PDA. A large number of devices have been designed and tested both in animal models and human subjects, but only few devices (free and...
