Fig. 2From: Contribution of sarcomere gene mutations to left atrial function in patients with hypertrophic cardiomyopathyComparison of prevalence of atrial fibrillation (a), left atrial volume index (b), and a’ velocity (c) and left atrial total emptying fraction (d) between sarcomere gene mutation-positive group and mutation-negative group. Comparison of left atrial volume index (e), and a’ (f) velocity between sarcomere- and mitochondria-related gene mutation groups*. HCM, hypertrophic cardiomyopathy; AF, atrial fibrillation, LA, left atrial, TDI, tissue Doppler imaging; a’, peak late-diastolic septal mitral annular; CMR, cardiac magnetic resonance imaging; bar indicates standard error; *one patient was missed due to non-analysis of mtDNABack to article page
