The Right

Arrhythmogenic right ventricular dysplasia (ARVD) is an inheritable heart muscle disease that predominantly affects the right ventricle (RV) and predisposes to ventricular arrhythmias and sudden cardiac death (SCD)1. The natural history is predominantly related to ventricular electric instability which may lead to arrhythmic SCD, mostly in young people and athletes2,3, but may progress with significant RV muscle disease and left-ventricular (LV) involvement and can result in right or biventricular heart failure4. We report on a 54-year-old male with ARVD who underwent an epicardial ventricular tachycardia (VT) ablation using remote magnetic navigation (RMN) after functional imaging from a nuclear perfusion study was fused with a 3D segmentation from computed tomography (CT) imaging.

The Relationship

Background. The relationship between C-reactive protein (CRP) elevation and ventricular tachycardia (VT) in arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is unclear.Methods and Results. In 91 consecutive patients with either ARVD/C with or without VT (cases) or idiopathic right ventricular outflow tract (RVOT) tachycardia (controls), blood sampling were taken to determine CRP levels. In ARVD/C patients with VT, we analyzed the association between VT occurrences and CRP level. Sixty patients had ARVD/C, and 31 had idiopathic RVOT VT. Patients with ARVD/C had a significant higher level of CRP compared to those with RVOT VT (3.5±4.9versus1.1±1.2 mg/l,P=.0004). In ARVD/C group, 77%, (n=46) patients experienced VT. Of these, 37% (n=17) underwent blood testing for CRP within 24 h after the onset of VT and the remaining 63% (n=29) after 24 h of VT reduction. CRP level was similar in ARVD/C patients with or without documented VT (3.6±5.1 mg/l versus3.1±4.1 mg/l,P=.372). However, in patients with ARVD/C and documented VT, CRP was significantly higher when measured within 24 hours following VT in comparison to that level when measured after 24 h (4.9±6.2 mg/l versus3.0±4.4 mg/l,P=.049).Conclusion. Inflammatory state is an active process in patients with ARVD/C. Moreover, there is a higher level of CRP in patients soon after ventricular tachycardia, and this probably tends to decrease after the event.
