Syncope in hypertrophic cardiomyopathy.
Key result
Syncope in a patient with hypertrophic cardiomyopathy was attributed to a primary haemodynamic mechanism, such as reduced left ventricular volume, rather than an arrhythmia.

Implication
May prompt hemodynamic evaluation in HCM syncope; hypothesis-generating and leaves open arrhythmia prevalence pending larger studies.

Mechanism of syncope
This case report suggests that syncope in hypertrophic cardiomyopathy can be driven by primary haemodynamic mechanisms, such as a reduction in left ventricular volume, rather than arrhythmias.
