Abstract The aim to study was to assess Strain of papillary muscles (PM) and their apical displacement with 3D mitral valve (MV) parameters with maximal size of gradient of obstruction in the left ventricle outflow tract (LVOFT) and the volume of mitral regurgitation (MR) in hypertrophic cardiomyopathy (HCMP) patients. Material and methods. 72 HCMP patients (aged of 56.9 ± 11.1 years and gradient in LVOFT 70.83 ± 14.83 mm Hg at rest) were investigated. 3D TEE of MV was performed in all patients with follow up reconstruction. Strain of anterolateral (AL) and posteromedial (PM) papillary muscles (PM) was assess by TTE. Results Strain of both PM was decreased in 45 (62.5)% patients. Positive Strain PM PM were found in 20 (27.8%) patients and AL PM -in 7 (9.7%) patients. Apical displacement of PM PM were registered in 19 (38.0%) pts and ALPM in 6 (12.0%) pts. Apical displacement of both papillary muscles was found in 10 (20.0%) patients. Pts with positive Strain of PM PM had remodeling fibrous ring of MV as compared to patients who had negative Strain of this PM (anteroposterior diameter - 1.97 ± 0.23 sm/m² vs 1.63 ± 0.20sm/m²; p = 0, 01; the perimeter of the ring - 6.92 ± 0.69 sm/m2 vs 6.09 ± 0.93sm/m2; p = 0.02; the area of the ring (3D) - 6.91 ± 1.23sm²/m² vs 5,14 ± 1.31 sm²/m²; p = 0.005). These patients had large areas of the MV leaflets (anterior 4.83 ± 1.03 sm²/m² vs 3.19 ± 0.81 sm² /m² ; p = 0.007; posterior - 4.39 ± 0.42 sm²/m² vs 3.39 ± 1.18 sm²2/m²; p = 0.004), the area of the tenting of leaflets (2.98 ± 1.64 sm²/m² vs 1.24 ± 0.61 sm²/m²; p = 0.04) and the fraction of the tenting (69, 04 ± 24.9% vs 41.27 ± 17.59; p = 0.03). Patients with positive Strain had a greater volume of mitral regurgitation (24.20 ± 11.91 ml vs 14.04 ± 7.58 ml p = 0.004) and the peak gradient in LVOFT was 88.90 ± 37.90 mm Hg vs 66.35 ± 27.00 mm Hg; p = 0.02). Thus, the parameters of 3D MV and strain of PM represent a fixed papillary – annular continuum causing a dynamic component of the obstruction in the LV OT and the volume of mitral regurgitation in patients with HCMP.
