Cardiovascular Magnetic Resonance in Assessing Decellularized Pulmonary Valve Allotransplantats in Pulmonary Position Twenty patients with decellularized pulmonary valve allotransplantats in pulmonary position were examined with a 1.5T magnetic resonance imaging unit to assess the diagnostic value of magnetic resonance imaging and clinical performance of the pulmonary allotransplantats replacement. The imaging protocol comprised time-resolved magnetic resonance angiography, axial and short axis cine imaging, for right ventricle functional analysis and phase-contrast velocity encoding imaging, for pulmonary valve and allotransplantats flow evaluation. Time-resolved magnetic resonance angiography yielded diagnostic image data in all examined patients and found normal anatomical and functional information. Axial cine imaging shows right ventricular ejection fraction 51.7 Ѓ} 11.7%, median 54.3%. Phase-contrast velocity encoding imaging revealed 7.7 Ѓ} 2.6 mm Hg peak pressure gradient, median - 7.1 mm Hg for pulmonary valve allotransplantats and 8.6 Ѓ} 4.66 mm Hg peak pressure gradient, median - 8.3 mm Hg, for pulmonary allotransplantats minimal diameter. Regurgitation fraction of pulmonary allotransplantats valve was 14.1 Ѓ} 15%, median 14.4%. Magnetic resonance imaging yields clinically relevant information in patients with decellularized pulmonary allotransplantats. Decellularized pulmonary allotransplantats showed good peak pressure gradient and were associated with normal right ventricle function. |
