| Summary: | Introduction: The left coronary artery shows a wide range of
morphological variations which has great clinical importance.
Difficulties may occur during performance of diagnostic procedures, especially in patients who undergo evaluation of
percutaneous coronary interventions or during coronary artery
surgeries or prosthetic valve replacements. Even, it has been
found that short length of main left coronary artery was one of
the congenital factors which predisposed to the development of
coronary artery disease. The aim of this work was to determine
the variations in the origin, length and divisions of the left coronary
artery trunk in the eastern region population of India.
Materials and Methods: The present study was carried out
on 100 heart samples which were collected from a mixed race
population group from West Bengal, India, after preserving them
in 10% formalin solution. While carefully maintaining all standard
precautions, scientifically well-planned cadaveric dissections
were done and variations were noted.
Results: It was found that in all specimens, left coronary artery
arose from single ostia at the left posterior aortic sinus. In about
65% cases, ostia was below or at the sinotubular junction (STJ)
and in a significant number (35%) of cases, it is above the level of
STJ. The mean length of the left coronary artery trunk was found
to be 11.42±4.98 mm. LMCA were bifurcated in 56% cases, they
were trifurcated in 40% cases and they were tetrafurcated in 2%
cases. The results were compared with those of other studies,
which showed considerable variations.
Conclusion: Thus, this morphometric study done on left coronary
artery trunk in the eastern Indian population will be helpful
for interventional cardiologists and radiologists for avoiding
inadvertent vascular trauma during diagnostic and therapeutic
procedures. |
