Gunda et al reported a score for complications associated with ablation of ventricular tachycardia. This can help to identify a patient who may benefit from more aggressive management. The authors are from Virginia Commonwealth University in Richmond.
Patient selection: catheter ablation
Outcome: any complication (vascular, cardiac, pulmonary, cerebrovascular, shock, septicemia, in-hospital mortality)
Parameters:
(1) age in years
(2) sex
(3) coagulopathy
(4) chronic liver disease
(5) chronic kidney disease with electrolyte abnormalities
(6) acuity of admission
(7) cerebrovascular accident
(8) coronary artery disease
(9) peripheral vascular disease

total score =
= SUM(points for all 9 parameters)
Interpretation:
• minimum score: 0
• maximum score: 27
• The higher the score the greater the risk for complicaitons.
