MORPHOMETRIC ANALYSIS OF AORTIC ROOT AND AORTIC VALVE: A CADAVERIC STUDY

Aortic valve present between left ventricle and ascending aorta has a trifoliate structure. Defect in aortic valve results in pathology like aortic regurgitation and aortic stenosis. For management of severe aortic regurgitation and aortic stenosis, aortic valve replacement is done. To avoid interventional complications related to aortic valve we should have proper database on aortic root and aortic valve morphometry. This study was done to measure the morphometry of aortic root and aortic valve. 41 cadaveric hearts without any gross pathology were obtained from dissection hall of Anatomy department, Motilal Nehru Medical College, Prayagraj. Age and gender were not determined. All parameters were measured with the help of vernier caliper and thread. After measurement data were statistically analyzed. Mean value of following parameters were determined such as- aortic root circumference-84.72±14.44 mm, cusps height of right, left and non-coronary was 11.41±3.14mm, 12.25±2.62mm and 12.30±3.11mm respectively, external intercommissural distance of right, left and non-coronary cups were 25.25±4.65mm, 23.97±5.69 mm and 25.36±5.23mm respectively, sinotubular junction circumference was-73.42±14.34mm, cusps length of right, left and non-coronary were 25.02±6.76mm, 25.57±6 mm and 24.3±5.7 respectively, width between right and non-coronary cusp was 5.6±2.17 mm, between left and noncoronary cusp 5.25±2.4mm and nally between right and left coronary cusp was 5.40±1.91mm. Our study provides a reference data which may be useful for cardiothoracic surgeons, radiologist and in prosthesis device designing.
