Ablation of Ventricular Arrhythmia

Ablation of Ventricular Arrhythmia, Volume and Success Rates

2018, N = 249

Cleveland Clinic is a national referral center for patients with ventricular arrhythmias. In 2018, a total of 249 ablationsᵃ were performed.

N Percent
Completely Successful 212 85.1
Unsuccessful 29 11.6
Not Targeted 4 1.6
Aborted 4 1.6
Total 249

ᵃExcludes n = 1 rescue / salvage procedure.

Ventricular arrhythmias are abnormal heart rhythms that originate in the bottom chambers of the heart (ventricles). The multidisciplinary team of doctors, nurses, and healthcare professionals in the Sydell and Arnold Miller Family Heart & Vascular Ventricular Arrhythmia Center are dedicated to diagnosing and treating patients with ventricular arrhythmias.

Major Complications Among Patients with Ejection Fraction < 50%

2018, N = 130

A major complication of ablation of ventricular arrhythmias 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

Major Complication Volume Percent of Patients
Death within 30 days of procedure 2 1.54
Pericardial effusion with surgical intervention 1 0.77
Vascular dissection / laceration 1 0.77
Pseudoaneurysm 1 0.77
Totalᵃ 5 3.85

ᵃMajor complications exclude n = 1 rescue / salvage case.
