Correlations between net pulmonary flow and aortic flow. a In HCM patients with and without LVOT obstruction (LVOTO). b In the control group. Black solid line indicates agreement (equality line denoting perfect agreement between measurements). Blue dashed line indicates the trend line (correlation) in HCM patients without LVOTO (blue circles). Red dashed line indicates the trend line (correlation) in HCM patients with LVOTO (red squares). Green dashed line indicates the trend line (correlation) in control subjects (green triangles). For HCM patients without LVOT obstruction and for the control group, the trend (correlation) line almost fits the equality line, confirming almost perfect agreement between aortic and pulmonary flow. For HCM patients with LVOT obstruction, overestimation of aortic flow compared to pulmonary flow (demonstrated as the discrepancy between the agreement and trend lines) was observed
