Abstract

Left atrial appendage closure (LAAC) is an efficient alternative of oral anticoagulation to prevent stroke in patients with non-valvular atrial fibrillation (NVAF). Due to complexities of LAA anatomy, a complete closure may not always be obtained with a single device. The aim of this study was to evaluate the feasibility and safety of the staged 'kissing-Watchman' technology to occlude the LAA with complex anatomy. In our center, among 300 cases underwent LAAC with Watchman device from February 2012 to December 2016, 7 complex LAAs were implanted double devices using the staged 'kissing-Watchman' technology. The anatomic morphology, procedure characteristics and safety were analyzed. Of the 7 LAAs, the anatomic morphology includes 6 cauliflowers and 1 chicken wings, each has 2 big lobes and a large common ostium. In the two-staged LAAC procedures, there were no differences in X-ray exposure time, but the total procedure time (p = 0.0634), contrast volume (p = 0.0802) and X-ray dose (p = 0.0803) in the first procedure showed a tendency over the second. All the procedures were successful, except for one case with a 2 mm of peri-device leakage, there were no severe complications or major adverse events including device dislocation...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.
