Abstract
Background: Coronary artery diameters are decisive for interventional radiologists and cardiologists. This helps them in choosing the stent size appropriately, based on the need and diameter of the vessel. An important factor affecting the diagnostic, therapeutic and prognostic purposes for patients is gender. Angiography has been the gold standard in establishing the accurate size of coronary artery, but it has certain limitations. On the other hand, Computed Tomography (CT) coronary angiography is better in terms of evaluating the size of vessel, mural thickness as well as calcified and non-calcified plaques.
Objective: Our purpose of study is to establish data for normal coronary artery diameters using multi-detector CT as our tool, in individuals without prevailing heart disease. Coronary artery diameters are decisive for interventional radiologists and cardiologists. This helps them in choosing the stent size appropriately, based on the need and diameter of the vessel. An important factor affecting the diagnostic, therapeutic and prognostic purposes for patients is gender. For reference, a vessel
Material and Methods: We randomly selected 180 consecutive patients without any underlying disease who underwent CT coronary angiography for evaluation of Coronary Artery Disease, between August 2020 and August 2021. CT coronary angiography based vessel diameters were analyzed on Vitrea on 64 slice. Patient’s demographics and data were obtained from our hospital record system Radiology Information System (RIS).
Results: In our study we found that the mean indexed diameter to BSA among males and females for LM 3.96mm with SD 0.585, LAD 3.62mm with SD 0.515 , LCX 2.99mm with SD 0.629 and RCA 3.13mm with SD 0.532. These values are comparable to other studies.
Conclusion: In a normal adult Pakistani population, the normative data for coronary artery are this is similar to that reported in Indian and western population
