Why the study?
The study aimed to examine the morphology of the middle cardiac vein in human hearts.
The middle cardiac vein has a mean diameter of 2.57 mm and length of 74.69 mm, providing anatomical basis for its potential use in radiofrequency ablation and pacing lead implantation.
Cadaveric vein measurements warrant caution before procedural application; leaves open in vivo validation and clinical correlation.
The aim of present study was to study morphology of middle cardiac vein in human hearts. The study was conducted on middle cardiac vein of thirty human hearts with due clearance from ethical committee. The mean diameter of middle cardiac vein was 2.57 1.16 mm and the mean length was 74.69 ± 21.10 mm. There was also statistically significant relationship between length of middle cardiac vein and weight of cadaver. In some hearts middle cardiac vein and small cardiac vein together form common trunk and then drain into coronary sinus. Middle cardiac vein can be used for radio frequency ablation of a posteroseptal pathway. It can also be used for newer interventional technique such as selective catheterization. It may be one of the choices of implantation of pacing leads.
