Implication

May support surgery for select refractory VT cases; leaves open safety and efficacy questions given Level 5 evidence.

Key Points

Evaluate the effectiveness of surgical interventions, including sympathectomy and aneurysm resection, for controlling recurrent ventricular tachycardia refractory to maximal antiarrhythmic medical therapy.
Evaluated 5 patients (4 with ischaemic heart disease) undergoing sympathectomy for recurrent ventricular tachycardia lasting from 6 weeks to 24 months.
Assessed 12 post-myocardial infarction patients undergoing surgical resection of a focal asynergic area (n=3) or ventricular aneurysm (n=9).
Following sympathectomy (n=5), complete abolition of ventricular tachycardia occurred in 2 patients (arrhythmia-free for 2 to 8 years), with no effect in 2 patients and temporary relief in 1.
Following surgical resection (n=12), ventricular irritability was permanently abolished in 7 patients followed for 1 month to 1 year, while 3 patients died in the immediate postoperative period and 2 had temporary relief.

Structured PICO

Does surgical treatment (sympathectomy or resection) abolish recurrent ventricular tachycardia in patients refractory to medical therapy?

Population

17 patients with recurrent ventricular tachycardia refractory to maximum doses of antiarrhythmic agents, including 5 patients undergoing sympathectomy (4 with ischaemic heart disease) and 12 patients undergoing resection post-myocardial infarction.

Intervention

Surgical treatment consisting of either sympathectomy (n=5) or resection of a focal asynergic area or ventricular aneurysm (n=12).

Outcome

Abolition of abnormal ventricular activity/irritability.hard clinical

Surgical interventions such as sympathectomy or aneurysm resection can abolish medically refractory recurrent ventricular tachycardia in a subset of patients, though associated with significant perioperative mortality.
