“…The papillary muscle and the chordae tendinae present in the right ventricle varies in the size, shape and length which is of very much significant clinical importance since the papillary muscle in the right ventricle plays an important role by helping in contraction of the right ventricle by drawing the tricuspid valve towards the apex and causing the shortening of the long axis and the chamber becomes spherical which helps in ejecting the blood. 2 Observation regarding the percentage of papillary muscles in the present study was in agreement with the work of Nigiri GR et al Other works by Balachandra N et al, Wafae N et al and Motabagani MAB are also in agreement with the present study but, percentage of septal papillary muscles noted in present study was 95.8% which was different in above mentioned studies. Possible reason for such difference is the number of specimens studied.…”

Aim of the present study was to observe the measurements of anterior papillary muscles present in tricuspid valve of human heart. Measurements of anterior papillary muscles in tricuspid valve gains utmost importance in cardiac surgeries because they are the causes of myocardial infarction in recent times because of its variations and detection of these causes by advent in modern technologies which will help in treatment of tricuspid valve diseases. This study was carried out on 96 normal formalin fixed human heart specimens. Dissection was performed according to standard techniques. Anterior papillary muscles were observed and length, width and thickness of each muscle were measured and documented. In the present study, numbers of anterior papillary muscles were present with a frequency of 1-3, with most common appearance of 1 muscle in 66 hearts (68.8%) and least common incidence of 3 muscles in 6 hearts (6.3%). Anterior papillary muscles were present in all 96 hearts. In measurements, anterior papillary muscles mean height was 1.49±0.44 cm; mean width was 0.82±0.21 cm and mean thickness was 0.64±0.15 cm respectively. We hope this study will serve to understand the morphometry of anterior papillary muscles better and will help in various surgical procedures and cardiac treatment done on tricuspid valve.

“…The function of the ventricular papillary muscles is to prevent overextension by drawing atrioventricular valve annulus toward the apex. 1 In the right ventricle which has three papillary muscles, anterior papillary muscle is largest while the septal papillary muscle is relatively small. In the left ventricle, the two papillary muscles supporting the cusps of the mitral valve may be bifid and they also vary in length as well as breadth.…”

Background: In both ventricles of the heart papillary muscles play important role for proper cardiac valvular function of heart. The present study was done to analyse the papillary muscles of heart with respect to the variations in their number, length, shape, position and pattern in both ventricles. Materials and Methods: Forty well preserved cadaveric human hearts were used for the study. The variations in the papillary muscles of both right and left ventricles were categorized, documented and photographed. Results: In the right ventricle, authors observed 31.42% anterior, 34.3% posterior and 34.3% septal papillary muscles, and in the left ventricle, 41.7% anterior and 58.3% posterior papillary muscles. Classical papillary muscles were observed in 64.3% heart specimens in right ventricle and 55% in left ventricle. Authors found conical, pyramidal and broad apexed papillary muscles in 44.3%, 51.4% and 4.3% heart specimens respectively in right ventricle, whereas in left ventricle the corresponding values were 33.3%, 30% and 36.7%. Separate bases and fused apex pattern was observed in 24.3%, single base and divided apex in 55.7% heart specimens in right ventricle and in left ventricle in 45% and 43.3% heart specimens respectively. The length of anterior, posterior and septal papillary muscle in right ventricle was 1.27±0.45, 1.36±0.52, 0.92±0.54 cm respectively whereas in left ventricle, the mean length of anterior and posterior papillary muscles was 2.13±0.44 and 1.76±0.46 cm. In right ventricle mean thickness was 1.17±0.31cm whereas in left ventricle it was 2.16±0.32 cm. Conclusion: The papillary muscles has complex and variable anatomy. Knowledge of this variation to the cardiac surgeons during reparative surgical procedures conducted for mitral/ tricuspid valve replacement is of utmost importance to prevent untoward event.

“…Mitral valve repair for congenital MVR in adults has been described many times in the literature [Tomita 1997;Hashimoto 2001;Shiran 2004;Zegdi 2005;Aramendi 2006;Mohammadi 2006]. The feasibility of mitral valvuloplasty depends on 2 factors: the availability of a sufficient amount of leafl et tissue and the pliability of the tissue (ie, nonfi brotic or noncalcifi ed).…”

“…Congenital mitral valve regurgitation (MVR) is a rare disease with a wide array of lesions that challenge surgical management. The disorder is seen primarily in infants and children, although there are many case reports of MVR in adult patients due to congenital mitral valve lesions [Tomita 1997;Hashimoto 2001;Shiran 2004;Zegdi 2005;Aramendi 2006;Mohammadi 2006]. Mitral valve repair can provide satisfactory long-term results [Chauvaud 1998;Ohno 1999] and is preferable to mitral valve replacement, which is associated with a poor prognosis in children [Beierlein 2007].…”
