The association of single ventricle morphology with long term quality of life among survivors: A report from congenital heart disease project to understand lifelong survivor experience (congenital heart disease (CHD) PULSE)

Am Heart JPublished

  • cross-sectional cohort study
  • survey conducted from 2021 to 2023
  • 11 US Pediatric Cardiac Care Consortium centers

Authors' conclusion

Ventricular morphology was not associated with differences in long-term outcomes. Adults with SV CHD have medical, neurocognitive, and socioeconomic differences compared to siblings, but similar PROMIS scores compared to the general population.

Study context

Population
Adults with single ventricle (SV) congenital heart disease (CHD) interventions and siblings226 SV patients and 40 siblings · SV patients 226 · siblings 40
Participants
146 / 80 / 40
Exposure
left vs right ventricular morphology; SV CHD patients vs siblings
  • left ventricularn = 146
  • right ventricularn = 80
  • siblingsn = 40

Main finding

As reported in the abstract

Outcomes by ventricular morphology
  • No outcome differences were found between left and right ventricular groups

Observational data: associations, not effects.

Further findings

Medical comorbidities, future health concerns, disability benefits, work affected by health (SV patients vs siblings)

SV patients reported more medical comorbidities
P < 0.001
SV patients reported more future health concerns
0.008
SV patients reported more disability benefits
P < 0.001
SV patients reported more work affected by health
P < 0.001

College/graduate degrees and employment (siblings vs SV patients)

Siblings had higher rates of college/graduate degrees
P = 0.002
Siblings had higher rates of employment
P = 0.044

Education and employment among SV patients

SV patients completed high school
95.6%
SV patients had college/graduate degrees
45.6%
SV patients were employed
73.9%

Patient-Reported Outcomes Measurement Information System (PROMIS) scores (SV patients vs siblings)

SV patients had lower PROMIS scores for global mental health and physical function
Similar scores for global physical health, cognitive function, anxiety, depression, and ability to participate in social roles
