A 77-year-old man with a healed transmural myocardial infarction has a medically refractory ventricular arrhythmia. The following is/are true: 


  1. Direct current catheter endocardial ablation has a high likelihood of success.
  2. If the arrhythmia is inducible at EP study, there is an indication for operative intervention.
  3. A recent MI would be a contraindication to operation
  4. Ventricular failure would be a contraindication to operation
  5. Monomorphic ventricular tachycardia is least amenable to surgical resection

b. If the arrhythmia is inducible at EP study, there is an indication for operative intervention.

c. A recent MI would be a contraindication to operation

d. Ventricular failure would be a contraindication to operation

After catheter ablation, only 25% of patients remain free of ventricular arrhythmia off of drug therapy. If the arrhythmia is inducible at EP study and the patient is an acceptable risk, with a myocardial scar he has an indication for operation. Both recent MI and ventricular failure are contraindications to operation. Monomorphic ventricular tachycardia is the arrhythmia most amenable to surgical resection.
