Phenotype was investigated in 86 patients with idiopathic prolapses of atrioventricular valves and in 21 patients with displaced chordae. 10 and 4 markers of connective tissue dysplasia were distinguished for patients with the prolapses and anomalous chordae, respectively. For patients with dysplasia of connective tissue of the heart a modified version of phenotypical length is proposed: norm-anomalous chordae--prolapse of the 1st degree--prolapse of the 2nd degree. For patients with 3 and more markers echo-CG registration is advisable to reject mitral and/or tricuspid valves.
