Abstract

Intra-atrial communication was mandatory for several congenital cardiac diseases, such as pulmonary atresia with intact ventricular septum (PA/IVS), and either sided aortoventricular valve atresia. We assessed whether the new methods of atrial septal defect(ASD)creation was effective. We experienced 4 cases of the surgical atrial septostomy performed under on-pump beating. We used a new device, a circular punch out defect creator. All cases were alive. The mean ASD diameter was enlarged from 4.37 mm to 5.55 mm and the mean ASD shunt flow was significantly decreased from 1.47 m/s to 1.11 m/s. We performed the surgical atrial septostomy using an aortic puncher under beating heart effectively and safely.

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.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

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.
