Functional and structural reverse myocardial remodeling following transcatheter aortic valve replacement: a prospective cardiovascular magnetic resonance study

Table 4 Regression analysis of CMR-derived myocardial fibrosis over 1 year

Independent variable	Dependent variable	Univariate regression coefficient	p-value
LV matrix volume	Δ GLS	0.42	0.006
	Δ GCS	0.44	0.03
	Δ LA Es	− 0.44	0.02
	Δ LA Ea	− 0.3	0.008
LV cellular volume	Δ GLS	0.57	0.002

	Δ LA Ea	− 0.51	0.01

Regression analyses to assess the influence of CMR-based tissue composition strain alterations. All delta values (Δ) were calculated (baseline–follow up). Es: reservoir strain, Ea: boosterpump strain, GLS: global longitudinal strain, GCS: global circumferential strain, LA: left atrial, LV: left ventricular
