The technology uses an expandable implant that blocks off the left atrial appendage (LAA) by angiography -- a minimally-invasive treatment to prevent strokes caused by blood clots forming in the LAAin patients who suffer from atrial fibrillation, or irregular heartbeats.
This is the first randomised study to show that closure of the left atrial appendage during open heart surgery effectively protects against brain infarctions and stroke, said Assoc Prof Helena Domnguez, the cardiologist who designed the study.
However, in second patient right pulmonary vein was rerouted by two pericardial patches and left pulmonary vein draining into vertical vein was rerouted by side to side anastomosis between vertical vein and left atrial appendage.
NNA - The Cardiac electrophysiology team at the American University of Beirut Medical Center (AUBMC) performed on Tuesday July 7, 2015 a Watchman left atrial appendage closure device implantation on two consecutive patients with atrial fibrillation and high risk of bleeding.
Additionally, new devices that close off the left atrial appendage (an important source of strokes in atrial fibrillation) are a treatment option for patients who cannot take warfarin or other blood thinners.
