Abstract

Objectives: Describe the magnetic resonance imaging characteristics of hypertrophic cardiomyopathy.


Subjects and methods: A prospective, cross-sectional study on 30 patients with hypertrophic cardiomyopathy at the Vietnam Heart Institute, undergoing cardiac magnetic resonance imaging at the Center for Radiology, Bach Mai Hospital from July 2021 to September 2022.


Result: Maximum wall thickness is 37 mm, mid anteroseptal: 21.8 ± 6.17 mm; mid anterolateral: 20.6 ± 3.98 mm, basal inferolateral: 15,9 ± 1.77 mm, basal inferior: 15.9 ± 0.71 mm. 6.7% hypertrophy of both ventricles; 13.3% concentric hypertrophy; 40% diffuse eccentricity; 30% deviation of the entire interventricular septum and 3.3% of the apex. Mean ejection fraction: 65.58 ± 9.02%; mean left ventricular mass: 181.98 ± 55.14 g, mean left ventricular outflow tract diameter: 9.56 ± 4.69 mm and ratio of left ventricular outflow tract diameter to annulus diameter host: 0.46 ± 0.23 mm. 46.7% presented late gadolinium enhancement and 46.7%. having signs of SAM.


Conclusion: The phenotypic characteristics, wall thickness, left ventricular mass, ejection fraction, late gadolinium enhancement and some other abnormalities associated with magnetic resonance imaging provide useful data for the treatment of hypertrophic cardiomyopathy.
