Comparison of non-invasive assessment for pulmonary vascular indices by two-dimensional echocardiography and cardiac computed tomography angiography with conventional catheter angiocardiography in unrepaired Tetralogy of Fallot physiology patients weighing more than 10 kg: a retrospective analysis
Authors' conclusion
For unrepaired TOF physiology patients weighing more than 10 kg, CTA-acquired PVD are reliable and comparable with CCA except for DA for which ECHO is non-inferior. Non-invasive modalities though are inferior to CCA for LPA sizing.
Study context
- Population
- Unrepaired Tetralogy of Fallot (TOF) physiology patients weighing >10 kg undergoing echocardiography (ECHO), computed tomography angiography (CTA) and cardiac catheterization and angiography (CCA) within a month before surgical correction, 2018–2020mean age 15.5 ± 9.3 years
- Participants
- 54 patients
- Comparison
- ECHO and CTA vs CCA for pulmonary vascular dimensions
- Outcome
- Reliability and correlation of ECHO and CTA pulmonary vascular dimension measurements (iPAnn, iRPA, iLPA, iDA, Nakata index, McGoon's ratio, pRV/pLV, Z-scores) with CCA
Performance
As reported in the abstract
- CTA and CCA measurements for iPAnn, indexed right pulmonary artery (iRPA), Nakata index (NI), McGoon's ratio (MGR), pRV/pLV and Z-score comparable; ECHO parameters significantly lower than CCA
- Indexed left pulmonary artery (iLPA) diameter significantly underestimated by ECHO and overestimated by CTA
- Stronger correlation of CTA- than ECHO-derived PVD with CCA, except for indexed descending aorta (iDA), pRV/pLV and Z-score
