The left ventricular lead position was localized based on LAO view and was divided into three equal regions as shown in [Figure 1]b: the anterolateral
cardiac vein (ALCV), the lateral
cardiac vein (LCV), and the posterolateral
cardiac vein (PLCV).
The coronary sinus commences at the point where the oblique vein of the left atrium joins the great
cardiac vein. The sinus receives the middle and small
cardiac veins close to its junction with the right atrium.
[47] showed that the PL lines were shortest among the three endocardial lines but closest to left circumflex artery and great
cardiac vein. Myocardium was thickest at the AL line, and sinus nodal arteries were frequently found on the AM and AL lines.
Its contents include the great
cardiac vein and the anterior interventricular artery.
The implant is designed to be positioned, adjusted, and gently anchored in the coronary sinus/great
cardiac vein (GCV) to reshape the annulus around the mitral valve to reduce mitral regurgitation.
Despite this adjustment, veins other than the proximal coronary veins (the CS, middle
cardiac vein, small
cardiac vein, and posterior vein) were not visualized optimally.
