Why is it important?

Tricuspid valve complex is commonly involved in various heart diseases like rheumatic heart diseases, congenital cardiac anomalies etc. Studies on Tricuspid valve complex, in Maharashtrians are few; so the present work was undertaken. Thirty five formalin fixed embalmed adult heart obtained by dissecting cadavers allotted to undergraduate students in GMC, Aurangabad, were studied irrespective of gender and cause of death. In present study circumference of tricuspid valve annulus was (mean +/- SD) 10.96 +/- 1.36 cm with range 8.6 cm to 13.6 cm; Diameter at minimum separated points (D1) was in the range of 2 cm to 3.5 cm and diameter measured at maximally separated points (D2) were in range 2.8 cm to 4.4 cm. Occurrence of papillary muscle was noted, anterior and posterior papillary muscle were present in all specimens however septal papillary muscle was absent in 9 out of 35 specimens. Anterior papillary muscle dimensions were noted; mean length for it was 1.224 cm +/- 0.478 cm with range 0.4 cm to 2 cm and mean thickness was 0.488 cm +/- 0.182 cm (range 0.3 cm to 0.9 cm).Knowledge of anatomy of tricuspid valve complex bears importance for operative procedures on tricuspid valve abnormalities. Present study data might be useful for cardiothoracic surgeons for newer surgical techniques like papillotomy, correction of papillary rupture induced tricuspid regurgitation.
