Cystic tumor of the atrioventricular node
of the heart appears to be the heart equivalent of the solid cell nests (ultimobranchial rests) ofthe thyroid.
Patients with right ventricular infarction due to RCA occlusion have a poor prognosis and a high risk of disturbances in conduction at the atrioventricular node
. Identification of the occluded vessel by using ECG signs and their validation can help in planning the PCI procedure and stratifying risk.
Complex electrophysiological characteristics in atrioventricular nodal reentrant tachycardia with continuous atrioventricular node
Last month, the Food and Drug Administration approved the Freezor Cryoablation System specifically for treatment of atrioventricular node
reentry tachycardia (AVNRT).
The literature contains a case report of aortic valve PFE coincident with a cystic tumor of the atrioventricular node
. Our case showed coincident PFE and thymoma.
Five pigs were treated with a modified adenovirus containing the gene that codes for the inhibitory G protein, a protein that is active in the heart's atrioventricular node
and helps control heartbeat.
The lengthening of the PR interval may indicate an infrahisian conduction disorder located on the right bundle or a delay in the atrioventricular node
In addition, some researchers suggested that patients with a PLSVC may become symptomatic due to arrhythmias through stretching of the atrioventricular node
or His bundle by the dilated coronary sinus.
Accelerated junctional rhythm may arise in atrial tissue proximal to the atrioventricular node
, in the atrioventricular node
itself, or in the His bundle and is the result of enhanced automaticity.
Origin of blood supply to sinoauricular and atrioventricular node
. Am Heart J 1968; 75: 279-808.
With the exception of endodermal heterotopia of the atrioventricular node
, primary cardiac tumors rarely cause sudden death. Among benign primary cardiac tumors, paraganglioma, a neuroendocrine neoplasm that arises from the extra-adrenal paraganglia of the autonomic nervous system, accounts for less than 1%.[2,3] The sites of origin in the heart parallel the anatomic distribution of visceral autonomic paraganglionic tissue, chiefly arising from the roof of the atria and atrial septum and from the branchiomeric aortopulmonary paraganglia.
The association of complete AV block and TCM remains a conundrum because the damaged apical ventricle is some distance away from the conduction pathways in the atrium, bundle of His, atrioventricular node
, and intrahisian region .
