1 Exercise gas exchange analysis in obstructive hypertrophic cardiomyopathy before and after myectomy (cardiopulmonary exercise test combined with exercise- echocardiography in HCM)  F. Bandera, G. Generati, M. Pellegrino, F. Secchi, L. Menicanti, M. Guazzi  International Journal of Cardiology  Volume 178, Pages (January 2015) DOI: /j.ijcard Copyright © 2014 Elsevier Ireland Ltd Terms and Conditions

2 Fig. 1 A: Exercise echocardiography and changes in gradients from rest to peak exercise. B: cardiac magnetic resonance with morphological (top) and late-enhancement (bottom) images showing turbulent flow at left ventricular outflow tract, mitral regurgitation secondary to mitral leaflet anterior movement (harrow) and gadolinium deposit in hypertrophic regions.

3 Fig. 2 ΔVO2/ΔWork Rate and VE/VCO2 slopes before and 6-months after surgery: the ΔVO2/ΔWork Rate flattening disappeared after surgery as well as ventilatory efficiency significantly improved.
