Heart failure & cardiomyopathies
Novel technique and assessment of available 3-dimensional delivery sheath for endomyocardial biopsy during cardiac device implantation
Authors' conclusion
All 3D delivery sheaths were safe and effective for performing EMB from the RVS during CIED implantation, enabling early CA diagnosis in 20% of patients.
Study context
- Population
- Patients undergoing cardiac implantable electronic device (CIED) implantation
- Participants
- 20 patients
- Exposure
- Three 3D delivery sheaths for endomyocardial biopsy (EMB) during CIED implantation
- Selectra 3Dn = 12
- CSP Locator 3Dn = 4
- SSPCn = 4
- Outcome
- EMB success rate and pathologic findings
Main finding
As reported in the abstract
EMB samples collected
77
Diagnosed with cardiac amyloidosis
4
20%
Observational data: associations, not effects.
Further findings
| Outcome | Selectra 3D | CSP Locator 3D | P value |
|---|---|---|---|
| Sheath deflection toward RV apex during bioptome insertion | |||
| Dis-RAO | 19.8 ± 3.8 mm | 13.2 ± 2.0 mm | P < 0.01 |
| Dis-LAO | 15.3 ± 3.9 mm | 8.1 ± 1.3 mm | P < 0.01 |
- Sheath deflection toward RV apex during bioptome insertion: only CSP Locator 3D vs Selectra 3D differed significantly
Safety
- 77 EMB samples from 20 patients collected without any complication
