Electroconvulsive therapy in the setting of implantable cardioverter-defibrillators

Area of Science:

• Psychiatry and Cardiology
• Neuroscience and Cardiovascular Medicine

Background:

• Electroconvulsive therapy (ECT) presents significant cardiovascular risks, complicating treatment for patients with pre-existing cardiac conditions.
• Major depression and cardiovascular disease often coexist, synergistically increasing patient morbidity and mortality.
• Managing patients with both refractory depression and comorbid cardiovascular disease, particularly those with implantable cardioverter-defibrillators (ICDs), remains a clinical challenge.

Observation:

• The study reports on three elderly patients with major depression and implanted ICDs who underwent ECT.
• All patients received effective treatment for their depression.
• No major adverse cardiovascular events were observed during or after the ECT procedures.

Findings:

• Careful planning and preventative measures allowed for the safe administration of ECT in patients with ICDs.
• The study demonstrates successful treatment of major depression in a high-risk cardiac population.
• The findings support the feasibility of ECT in patients with implanted cardioverter-defibrillators.

Implications:

• Appropriate preventative strategies can enable effective ECT for medically challenging patients with cardiovascular disease and ICDs.
• These cases highlight the need for standardized protocols regarding intraoperative management of ICDs during ECT.
• Further research is warranted to refine management guidelines for ECT in patients with cardiac implantable electronic devices.
