“…Their primary purpose is to leave the continuity between mitral annulus and papillary muscles intact. 3,7,[9][10][11][12][13] David et al also performed leaflet preserving techniques even in redo MVR operations. 31,32 We performed 43 bileaflet preserved MVR operations.…”

“…1,2 Lillehei et al noted this continuity between mitral annulus and papillary muscles and devised an operative method of mitral valve replacement (MVR) by preserving posterior leaflet and its apparatus. 3 They advocated that operative mortality and morbidity decreased and functional status of patients were improved. However, several studies demonstrated that isolated posterior leaflet preservation did not improve left ventricular performance 4,5 and anterior leaflet has critical role for left ventricular function by preserving geometry of left ventricle.…”

“…Lillehei et al [3] in 1963, based on Rushmer's physiological hypotheses, performed the first replacement of the mitral valve, preserving the papillary muscles and the chordae. Their results confirmed the functional importance of the subvalvar apparatus, showing a significant reduction in operative mortality of patients operated on by the team.…”

RBCCV 44205-769 Nova abordagem técnica para papilopexia cruzada em operação de substituição valvar mitral: resultados imediatosNew technical approach for crossed papillopexy in mitral valve replacement surgery: short term results Abstract Objective: To present the crossed papillopexy technique and its initial results in the preservation of papillary muscles in mitral valve replacement and ventricular remodeling surgeries for heart failure (CHF).Method: Ten patients, 70% male, with ages between 15 and 75 years old (mean 44.4 ± ± ± ± ± 18.7 years old), suffering from rheumatic mitral valve disease (50%), mitral valve prolapse (10%) or dilated cardiomyopathy (40%), were studied. After opening the left atrium and adequate exposure of the mitral valve, the anterior leaflet already free of its annulus fixation was centrally divided and each half, with its cordae tendineae complex fixed to the commissure on the opposite side. Following this, mechanical (seven cases) or biological (three cases) prostheses were implanted using single sutures in the valve annuli, with reduction of the mitral valve annulus for better ventricular remodeling in CHF cases.Results: All patients were discharged from hospital in good clinical conditions. Additionally all presented with great improvement in the cardiac performance at the end of the first month of follow-up, with significant reductions in the left ventricular and left atrium systolic diameters (p<0.05) and mean increases in the left ventricle ejection fraction of from 46.7 to 56.4 % (p<0.05).Conclusion: The crossed papillopexy technique in valve replacement surgeries for mitral valve lesions and CHF presented significant increases in the left ventricular function and improvement of ventricular remodeling in the studied postoperative period.

“…Chordal-sparing procedures in mitral valve replacement have had a major impact on patients' prognosis due to the preservation of the inherent structure of the subvalvular apparatus. [1][2][3] However, a potential hazard for mechanical prosthesis dysfunction due to extensive neo-intima formation or subvalvular apparatus impingement has already been described. 4 We report a case of early bioprosthetic mitral valve dysfunction as consequence of remnant papillary muscle and chordae tendineae impingement.…”
