The aim of the present study was to compare the size and function of the mitral annulus (MA) between CA patients and age- and gender-matched controls, using three-dimensional speckle-tracking echocardiography (3-D STE). METHODS: The study included 17 patients (mean age 64.2 +/- 9.8 years) with CA, whose results were compared to 26 age- and gender-matched healthy controls (mean age 59.0 +/- 8.2 years). Complete two-dimensional (2-D) Doppler echocardiography and 3-D STE were performed in all cases. RESULTS: Significantly enlarged end-diastolic and end-systolic MA diameters (3.09 +/- 0.56 cm versus 2.70 +/- 0.37 cm, p = 0.01 and 2.71 +/- 0.68 cm versus 1.87 +/- 0.31 cm, p <0.001) and MA area (11.22 +/- 3.56 cm2 versus 8.60 +/- 1.92 cm2, p = 0.004 and 8.57 +/- 3.35 cm2 versus 4.55 +/- 1.05 cm2, p <0.001) were demonstrated in CA. MA fractional area change (24.10 +/- 13.97% versus 46.06 +/- 14.37%, p <0.001) and MA fractional shortening (12.92 +/- 9.55% versus 30.98 +/- 11.65%, p <0.001) were also impaired in CA patients as compared to matched controls. CONCLUSIONS: CA is associated with MA enlargement and functional impairment represented by MA fractional shortening and MA fractional area change, as assessed using 3-D STE. date: 2017 type: Folyóiratcikk type: PeerReviewed format: text identifier: http://publicatio.bibl.u-szeged.hu/16336/1/3DSTE-MA-CAJHeartValveDis2017-2.pdf identifier: Nemes Attila; Földeák Dóra Melinda; Kormányos Árpád; Domsik Péter; Kalapos Anita; Borbényi Zita; Forster Tamás: Cardiac Amyloidosis Associated with Enlargement and Functional Impairment of the Mitral Annulus: Insights from the Three-Dimensional Speckle Tracking Echocardiographic MAGYAR-Path Study.
