Abstract

A device-related thrombus is a very common complication after the implantation of a Watchman device. Although anticoagulation therapy is the standard first choice therapy for a device-related thrombus, complications related to bleeding or existence of non-responders to the anticoagulation therapy are reported. Therefore, the possibility of another treatment, including surgical repair, needs to be discussed in the population unsuccessfully treated with anticoagulation therapy. We performed device-related thrombus removal and covered the orifice of the left atrial appendage with an autologous pericardial patch in 2 cases involving non-responders to anticoagulation therapy. Herein, we describe the technique and results of our experience with these 2 patients. The covering technique with an autologous pericardial patch is simple but highly efficient in preventing recurrent thrombus formation.

Atrial Filbrillation

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

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.

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.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
