Novel uses for implanted haemodynamic monitoring in adults with subaortic right ventricles
Authors' conclusion
Uses of IHM in patients with sRV are described which may minimise the need for serial catheterisations in a population where PH is prevalent. HFHs were low overall but not impacted by IHM. One device-related complication occurred without long-term consequence.
Study context
- Population
- Adults with subaortic RV (D-TGA after atrial switch or congenitally corrected TGA (ccTGA)), single centre, 2015–202216 D-TGA/AS, 2 ccTGA
- Participants
- 18 adults
- Exposure
- Before vs after invasive haemodynamic monitoring (IHM) placement
- Outcome
- Uses of IHM, impact of IHM on HF hospitalisation and device-related complications
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
Uses of IHM
- Medical therapy titration
- Medical management after ventricular assist device in patients with transplant-limiting pulmonary hypertension (PH)
- Serial monitoring of PA pressures without repeat catheterisations to help time heart transplant referral
Observational data: associations, not effects.
Further findings
Median
| Outcome | Before | After | P value |
|---|---|---|---|
| HF hospitalisations/year · median 23 months follow-up | 0 (IQR 0–1.0) | 0 (IQR 0–0.8) | P = 0.984 |
HF hospitalisations/year · median 23 months follow-up
- Heart failure hospitalisation (HFHs)/year similar to the year prior to IHM
Safety
- Device migration, without long-term sequelae
