ANATOMICAL AND RADIOLOGICAL STUDY OF CORONARY OSTIA IN ADULT HUMAN HEARTS

The annual number of deaths from cardiovascular diseases (CVD) in India jumped from 2.26 million (1990) to 4.77 million (2020). With the uptrend of CVD cases, the procedures related to coronary arteries also have tremendously increased. Accurate knowledge of the diameter of the coronary artery is needed to facilitate the various cardiac interventions for diagnostics and therapeutical purposes. Therefore, this study was aimed to measure and compare the diameter of the coronary artery from cadaveric hearts, and from living persons by quantitative coronary angiography and intravascular ultrasound. The present descriptive cross-sectional study was carried out on 40 embalmed hearts from the department of anatomy, P.D.U. Government medical college Rajkot, Gujarat 131 angiograms by QCA and 131 luminogram by IVUS technique from the department of cardiology, Synergy Superspeciality Hospital, Rajkot, Gujarat, after approval from the institutional ethical committee. The collected data by all three methods were compared and analyzed by standard statistical methods using Epi info software version 7.2. The mean diameter of RCA= 2.73mm, LCA=3.6mm, LAD=2.55mm and LCX=2.57mm measured from cadaveric hearts. The diameter measured by QCA were RCA=3.69±0.58mm, LCA=4.12±0.56mm, LAD=3.29±0.39mm, LCX=3.18±0.4mm and by IVUS RCA=4.78±0.59mm, LCA=5.72±0.59mm, LAD=4.49±0.5mm, LCX=4.47±0.53mm. The Pertinent finding of our study is that the diameter of LCA is greater than the RCA (p value<0.001) measured by all three methods the diameter of coronary arteries measured by IVUS is considerably larger than those measured by QCA. IVUS is a pivotal adjunct of QCA and has been increasingly used in clinical and research applications.
