ICD choice in heart failure

An International Multispecialty Survey

We are conducting an international survey to understand how clinicians choose between transvenous, subcutaneous, and extravascular ICD systems in patients with severe ischaemic cardiomyopathy (ICM), particularly when progression to left ventricular assist device (LVAD) or heart transplantation is possible.
This survey is fully anonymous.
No identifiable personal data are collected.
No IP addresses are stored. One response per device is enabled to minimise duplicate entries.
Completion time: approximately 5–6 minutes.

The aggregated dataset will be available for collaborative analyses with interested participants.
Please answer based on what you would most commonly do in your current practice setting.
1.Primary role(Required.)
2.In what country do you work?(Required.)
3.Practice setting(Required.)
4.Do you personally implant ICDs?(Required.)
5.Which ICD systems are available at your institution? (Select all)(Required.)
6.Annual ICD implant volume in your centre(Required.)
7.In severe ischaemic cardiomyopathy - ICM - (LVEF ≤35%) without pacing indication, how often do you consider future advanced HF therapies (LVAD or transplant) when selecting ICD type?(Required.)

9.In severe ischaemic cardiomyopathy (ICM), what is the most common ventricular arrhythmia phenotype requiring therapy in your experience?(Required.)
10.Approximately what proportion of severe ICM primary prevention patients receive appropriate ICD therapy within 5 years?(Required.)
11.In your view, ATP significantly reduces shock burden in ICM.(Required.)

12.55-year-old with ischaemic cardiomyopathy (ICM), LVEF 25%, NYHA II, QRS 110 ms, sinus rhythm, no pacing indication. Your device choice?
13.Same patient, still no pacing indication, actively evaluated for transplant (likely within 12–24 months). Your device choice?(Required.)
14.Same patient + extensive scar + frequent NSVT. Your device choice?(Required.)
15.Same patient + advanced CKD (eGFR <30). Your device choice?(Required.)
16.Same patient + prior systemic infection (device infection or valvular endocarditis). Your device choice?(Required.)
17.35-year-old with ICM, otherwise similar profile (LVEF 25%, NYHA 2, QRS 110 ms, sinus rhythm, no pacing indications). Your device choice?(Required.)
18.Highly active patient, no pacing indication. Your device choice?(Required.)
19.In a patient with severe ICM and rapidly progressive heart failure likely to require LVAD within 6 months, would you still recommend ICD implantation?(Required.)
20.Top 3 factors influencing ICD type selection (Select up to 3)(Required.)
21.What are the main barriers to S-ICD / EV-ICD use in your region? (Select up to 2)(Required.)
22.If EV-ICD (with ATP) or modular S-ICD (with ATP) were widely available and reimbursed, would you use it more frequently in ICM?(Required.)
23.Would you support the development of an international multispecialty consensus on ICD type selection in transplant-likely patients?
