Morphological and Morphometric Study of the Coronary Sinus and its Tributaries in Adult Cadaveric Hearts: A Descriptive Anatomical Study
By Mamillapalli Srilakshmi.
Abstract
Background
The coronary sinus (CS) is the principal venous conduit of the heart and provides an important route for cardiac electrophysiological and interventional procedures. Variations in its dimensions, ostium, valves, tributaries and relationship with surrounding structures may influence coronary sinus cannulation and device placement. This study evaluated the morphology and morphometry of the CS and its associated structures in adult cadaveric hearts.
Methods
This descriptive anatomical study included 58 formalin-fixed adult cadaveric hearts and was conducted from October 2022 to February 2025 at Sukh Sagar Medical College & Hospital, Chargawan, Jabalpur, Madhya Pradesh, India. The dimensions of the coronary sinus, coronary sinus ostium, left posterior atrioventricular sulcus and heart were measured. The morphology of the coronary sinus and Thebesian valve, myocardial covering, tributary drainage patterns, opening angles and the relationship of the coronary sinus with the left circumflex artery were recorded. Correlation analyses were performed, and a p value ≤0.05 was considered statistically significant.
