Study of Diaphragm Mobility on Tissue Doppler

Completed

• Conditions: Heart Surgery
• Interventions: Other: Diaphragm ultrasonography; Other: Tissue Doppler

• Registration Number: NCT03295344
• Lead Sponsor: Centre Hospitalier Universitaire Dijon

Brief Summary

Diaphragm dysfunction is found in 10 to 90% of patients following heart surgery.

In current practice diaphragm dysfunction is evaluated by 2D ultrasonography. Tissue Doppler is a validated technique to study heart contractility. Its use in the analysis of diaphragm function must be evaluated to determine its interest as a diagnostic tool.

Better understanding of diaphragm dysfunction following heart surgery will lead to earlier management of post-operative respiratory complications and the implementation of preventive pre-operative measures.

We intend to look for correlations between the TM (Time-Movement) mode and tissue Doppler in the assessment of diaphragm mobility.
