In the buffalo foetus of 3.0 cm CVRL, the ventricle was partitioned by the interventricular septum extended upward from the ventral side of heart toward the endocardial cushions leaving an opening in the interventricular foramen (Figure 3).
Dual left anterior descending coronary artery (LAD) is defined as the presence of two LADs within the anterior interventricular sulcus (AIVS): a short LAD that courses and terminates high in the AIVS, and a long LAD that originates from either the LAD proper or from the right coronary artery (RCA), then enters the distal AIVS and courses to the apex.
We also wanted to find out if there existed the difference in the value of the myocardial bridge muscle index (MI) between bridges located above the anterior interventricular branch (RIA) and bridges situated above other branches.
The transthoracic echocardiography revealed a round shaped, unilocular, double layered and well defined cystic lesion in the interventricular septum (IVS) protruding into the atrial septum and tricuspid septal annulus with a trivial pressure gradient (Fig.
The system is comprised of the Sonr hemodynamic sensor embedded in the Sonrtip atrial pacing lead and the Paradym RF Sonr CRT D device, which includes an algorithm designed to automatically optimize the patient's atrioventricular delay and interventricular delay timing.
