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.
