Ablation of Ventricular Arrhythmia Volume and Success Rates

N = 226

Cleveland Clinic is a national referral center for patients with ventricular arrhythmias. In 2017, a total of 226 ablations were performed. Partial success means that among patients with multiple arrhythmias, at least 1 arrhythmia was ablated.

N Percent
Completely Successful 182 80.5
Partially Successful 23 10.2
Unsuccessful 18 8
Not Targeted 1 0.4
Aborted 2 0.88
Total 226
AVAC Ejection Fraction<50%

2017, N = 115

A major complication is defined as one that leads to prolongation of hospital stay or to another hospitalization, requires additional intervention for treatment, and/or results in significant injury or death.¹
