METHOD OF CHOOSING TYPE OF RECONSTRUCTIVE CORRECTION OF HEART MITRAL VALVE INSUFFICIENCY Russian patent published in 2009 - IPC A61B8/12 

FIELD: medicine.

SUBSTANCE: intra-operation transesophageal echocardiography is performed. Additionally morphometry is performed after cardioplegia and cardiotomy, anatomical valve structures are measured and estimated: intercommisural distance, length of chords, state of chords, mobility of cusps and state of chords are evaluated in points: 0 points - thickening and/or shortening of chords, 1 point - normal state of valve chord apparatus, 2 points - elongation of supporting chords, 3 points - avulsion from papillary muscle or chord rupture; mobility of cusps is also evaluated in points: 0 points - mobility is limited because of rigidity of cusp and/or chord apparatus, 1 point - normal mobility, 2 points - mobility of cusp (cusps) is heightened, there is prolapse into left auricle not less than 7 mm deep, 3 points - cusp (cusps) freely turn out into auricle cavity. In case if said point sum does not exceed 1, valve replacement is indicated, if point sum is equal 2, isolated annuloplasty is indicated. If sum of points is within the range 4-6 resection of cusp segment is performed, in all other cases shortening or prosthetics of chords is indicated; annuloplasty method is chosen on the basis of intercommissural distance evaluation, in case if distance between commissures does not exceed 31 mm, suture annuloplasty or flexible semi-rings are used, if dimension of commissural space exceeds 31 mm, annuloplasty on rigid supporting ring is used.

EFFECT: increase of accuracy in choosing method of mitral valvular disease correction.
