Morphometric parameters of human coronary sinus - based on study of 80 human hearts

Area of Science:

• Cardiovascular Anatomy
• Human Anatomy

Background:

• The coronary sinus is a critical venous channel in the heart.
• Understanding its dimensions is vital for cardiovascular research and interventions.

Purpose of the Study:

• To investigate the morphometry of the coronary sinus in human hearts.
• To determine the influence of age and sex on coronary sinus dimensions.

Main Methods:

• Dissection and corrosion casting of 80 human hearts (64 male, 16 female) across four age groups.
• Injection of the venous vascular bed with Duracryl plus.
• Measurement of coronary sinus length and caliber using an electronic caliper.

Main Results:

• Coronary sinus length ranged from 15-50 mm (mean 30 mm in males, 25 mm in females).
• Vessel caliber ranged from 7-13 mm.
• Coronary sinus length was not age-dependent but was significantly longer in males.
• Male hearts exhibited a larger, though not statistically significant, coronary sinus caliber compared to females.

Conclusions:

• Sex is a significant factor in coronary sinus length, with males having longer vessels.
• Age does not appear to influence coronary sinus dimensions.
• While a trend exists, sex differences in coronary sinus caliber require further investigation for statistical significance.
