Контрастированная магнитно-резонансная томография у пациентов с перенесенным инфарктом миокарда и предсердными тахиаритмиями

Abstract

Представлены результаты использования магнитно-резонансной томографии (МРТ) сердца с парамагнитным контрастированием для визуального выявления очагов повреждения миокарда, провоцирующих развитие предсердных нарушений ритма у пациентов с перенесенным обширным инфарктом левого желудочка. Показано, что объем левого предсердия более 75 см 3 и накопление контраста-парамагнетика в миокарде предсердий с индексом усиления в Т1-взв. спин-эхо режиме более 1,27 являются прогностическими факторами в отношении развития наджелудочковых тахиаритмий, а МРТ сердца с контрастированием является важным дополнительным методом исследования у пациентов с предсердными нарушениями ритма сердца.

Contrast-enhanced MRI of the heart was employed for visual detection of risk as well of anatomic locations of atrial arrhythmias in patients with previous myocardial infarction. Data showed that pathologic uptake of paramagnetic to the atrial myocardium with enhancement index over 1.27 (in T1-weighted spin-echo mode) and concomitant increase of left atrial volume over 75 mL provided prognostic factor for manifestation of atrial tachyarrhythmias and endocardial destruction procedure in the nearest future. Therefore the contrast-enhanced MRI can be included to the diagnostic algorithm for patients with ischaemic heart disease and risk of supraventricular tachyarrhythmias.
