Background: The aim of present study is to evaluate the pattern of occurrence of Brocq and Mouchet’s arterio-venous triangle in human cadavers.
Methods: The present study was carried out in the Department of Anatomy at SRMS IMS, Bareilly from 2012-2014. Thirty human cadavers of both sexes fixed in 10 % formalin were dissected to observe the triangle of Brocq and Mouchet.
Results: The triangle was closed in 17 cadaveric hearts (56.66%). The triangle was opened in 13 cadaveric hearts (43.33%).It was opened inferiorly & superiorly in 5 cadaveric hearts (16.66%) each. The triangle was opened completely in rest of 3 cadaveric hearts (10%).
Conclusions: The triangle of Brocq and Mouchet is commonly used when performing an intravascular ultrasound of coronary arteries to help in identifying pericardium, myocardium and vessels in the neighborhood.
