The Atrioventricular Conduction Axis in Man and Mouse.

Those using the mouse for the purposes of electrophysiological research presume that the morphology of the conduction axis is comparable with the human arrangement. As yet, however, to the best of our knowledge, no direct comparison has been made between the species. By comparing our extensive histological findings in the human heart with comparable serially-sectioned datasets prepared from adult murine hearts, we aimed to provide this information.

Revisiting the Atrioventricular Conduction Axis for the 21st Century.

In this review, we summarise the ongoing debate surrounding the anatomy of the atrioventricular conduction axis and its relevance to pacing. We highlight previous disagreements and emphasise the importance of understanding the anatomical location of the axis. We give credit and support to the initial descriptions by His and Tawara, in particular their attention to the relationship of the atrioventricular conduction axis with the membranous septum.

Common arterial trunk with pulmonary atresia.

We report two congenitally malformed hearts found at autopsy to have common arterial trunk and pulmonary atresia. Both exhibited usual atrial arrangement, along with concordant atrioventricular connections. In one case, the common arterial trunk arose predominantly from the right ventricle, while the other had a balanced commitment.

Snapping Biceps Femoris Syndrome: A Case Presentation and Review of Current Literature.

Snapping of the biceps femoris tendon over the fibular head is a cause of symptomatic lateral knee pain. We presented the case of an active patient in his mid-20s who had bilateral snapping of his biceps femoris tendon, with no history of trauma. The pathophysiology in our case was thought to be secondary to prominent fibular heads.
