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.

Conditions

• Heart Surgery

Interventions

Type	Name	Description
OTHER	Diaphragm ultrasonography	Spontaneously breathing patients in the ½ seated position Heart transducer at the medio axillary position, parallel to the axis of the body, last intervertebral spaces US mode: 2D = Evaluation of the pulmonary parenchyma Time-Movement (TM) = Evaluation of diaphragm muscle shortening in the apposition zone + Evaluation of diaphragm mobility in the posterior 1/3 of the diaphragm dome Tissue Doppler Imaging (TDI) = Evaluation of diaphragm mobility in the diaphragm dome Collection of different daily clinical data
OTHER	Tissue Doppler	Determine the threshold value for diaphragm mobility
