Implication
RV parameters associated with arrest in ARVD subgroup; hypothesis-generating for risk stratification, prospective validation required.
Key Points
- Identify clinical, angiographic, and electrophysiological risk factors associated with sudden cardiac arrest in patients diagnosed with arrhythmogenic right ventricular dysplasia.
- Analyzed angiographic and electrophysiological records from 60 patients with angiographically confirmed arrhythmogenic right ventricular dysplasia.
- Stratified the cohort into three clinical presentation groups: spontaneous non-sustained ventricular arrhythmias (n=20), sustained ventricular tachycardia (n=27), and cardiac arrest with documented ventricular fibrillation (n=13).
- Found no statistically significant differences across arrhythmia subgroups regarding baseline right ventricular volume, global right ventricular ejection fraction, myocardial structure, mean age at diagnosis, or left ventricular contraction abnormalities.
- Identified significant associations with right ventricular volume (P < 0.05), right ventricular ejection fraction (P < 0.001), and structural alterations (P < 0.01) within the subgroup presenting with both cardiac arrest and inducible sustained ventricular tachycardia.
Structured PICO
What are the angiographic and electrophysiological risk factors for cardiac arrest in patients with arrhythmogenic right ventricular dysplasia?
P
Population
60 patients with angiographically documented arrhythmogenic right ventricular dysplasia (20 with spontaneous non-sustained ventricular arrhythmias, 27 with sustained ventricular tachycardia, and 13 who suffered cardiac arrest with documented ventricular fibrillation before resuscitation)
O
Outcome
Risk factors for cardiac arrest (angiographic and electrophysiological parameters)surrogate
Structural alterations and low right ventricular function identify a subgroup of patients with arrhythmogenic right ventricular dysplasia at high risk for cardiac arrest.
