0 relating to or happening in an atrium of the heart:
Premature beats that occur in the atria are called premature atrial contractions.
Rather than simply closing the septal defect, relieving the pulmonary stenosis, and performing an atrial switch, univentricular repair was preferred in these patients.
The long-term outlook for patients who have had surgical repair of atrial septal defects is generally extremely good, with minimal, if any, risk of endocarditis.
In both there was usual atrial arrangement with concordant atrioventricular and ventriculoarterial connections.
The sinus impulse is distributed through the plain working myocardium of the atrial walls to reach the atrioventricular junction.
We recently encountered two such cases, both with the segmental combination of mirror-imaged atrial arrangement, discordant atrioventricular connections, and double outlet right ventricle.
There is a complete atrioventricular septal defect with both an atrial and ventricular components seen.
Associated malformations are frequent, and include pulmonary stenosis or atresia, atrial or ventricular septal defects and, more rarely, atrioventricular septal defect.
At this stage, the wider curved end of the baffle is brought down onto the remnant of the atrial septum between the atrioventricular valves.
