SAM and tethering of the mitral valve are independent mechanisms with differing pathophysiology that can lead to acute MR in patients with TTC.

3DTEE provides substantial incremental value over TTE in the assessment of characteristic CHD pathology and thus enhances the echocardiographic diagnosis of CHD.

Age and the severity of MR were independent predictors for secondary PH in patients with TTC.

The use of atropine to augment the HR or RPP during SBESE (i) is safe; (ii) enables the assessment of ischaemia at peak effort; and (iii) allows assessment of exercise haemodynamics in patients with sub-maximal exercise capacity and chronotropic incompetence.
