CONCLUSION:
The findings in this case show that widely available techniques can be
used to unmask classic subtype of AC. Overall, for suspected
biventricular involved AC patients seem to experience more potentially
lethal ventricular arrhythmias than ARVD[14].
Therefore, the analysis of LV myocardial motion should be taken
seriously. However, it is difficult to discover minor LV involvement of
ARVD patients only through TTE. Our case highlights that AC was
diagnosed with multimodality imaging technology, minor LV dysfunction
detected by 2DSE and decreased RVEF indicated by RT-3DE, both of which
corresponding to the results of enhanced CMR imaging. In addition,
RT-3DE provided more realistic vision of locally dilated RV wall. These
might implied that 2DSE plus RT-3DE might be expected to alleviate the
dependency of enhanced CMR for suspected classic subtype of AC patients,
especially when some contraindications of enhanced CMR imaging, for
example, patients with metal implants, claustrophobia, a restless child
or elderly person, exist. Meanwhile, large cohort researches of patients
with AC are expected to confirm our findings.
