Abstract

Mitral homograft nakilleri için musculus papillaris’lerin anatomisinin iyi bilinmesi gerekir. Değişik yaşlara ait 60 kalpte (38 erkek, 22 kadın) chorda tendinea’ların dağılımı ve mitral kapağın sağ ve sol küspislerine tutunma seviyeleri incelendi. Papiller kaslar ve chorda tendinea’lar incelendi ve geometrik özellikleri ortaya konuldu. Sol ventrikül’ün papiller kasları üç grupta tanımlandı. Grup I (43.3%, 52/120)’de bazal bölüm ve kasların apeksi bölünmemişti. Grup II (30%, 36/120)’de iki başlı papiller kas vardı; alt-grup II/A (20%, 36/120)’da papiller kasın tabanı bölünmemişti ve alt-grup II/B (10%, 12/120)’de bölünmüş iki ayrı parça halinde papiller kas mevcuttu. Grup III (26.7%, 32/120)’te üç başlı papiller kas bulunmaktaydı. Aynı zamanda mitral kapağın ortalarında sonlanan 9-60 chordae tendineae olabileceği ve papiller kasın apeksinden başlayan 2-15 chordae tendineae olabileceği gözlendi. Bu konudaki yeni tiplendirmeler, endoskopik ve mitral kapak değişimleri veya chorda tendinea’ların rekonstrüksiyonu ve mitral kapak homogreft nakilleri sırasında önemli yol gösterecektir.

Özet

Mitral homograft replacement requires a good knowledge about anatomy of the papillary muscles. In 60 (38 male, 22 female) cardiac preparations of various age (16-44 ages), branch distribution of the chordae tendineae and level of their fixation to the ventricular surface of the right and left cusps of mitral valves have been studied. Papillary muscles and chordae tendineae were examined and their geometrical arrangement was determined. Three groups of the left ventricular papillary muscle were defined. In group I (43.3%, 52/120) the basal part and the apex of the muscle were undivided. In group II (30%, 36/120) there were two heads; in subgroup II/A (20%, 36/120) the base of the papillary muscle was undivided and in II/B (10%, 12/120) it was divided into two separate parts. In group III (26.7%, 32/120) the papillary muscle had three heads. It was also observed that 2 to 15 chordae tendineae can originate from the apex of papillary muscle and 9 to 60 chordae tendineae can ended into the corresponding half of the valve insertions. Thus these definitions and morphologic types may be of great value during endoscopic and conventional mitral valve replacement or reconstruction of the chordae tendineae and in mitral valve homograft implantations.
