2D Strain of Right Ventricle in Peroperative of Cardiac Surgery

2D Strain of Right Ventricle in Peroperative Cardiac Surgery : Evaluation of Early Signs of RV Dysfunction

Evaluation of the right ventricle (RV) deformation (strain) with 2D speckle tracking technics obtained by echocardiographies (TEE) in peroperative period of cardiac surgery .

TEE is performed for each patient of cardiac surgery during the operation time .

This new evaluation parameter of RV could be a good tool to assess the early RV dysfunction after cardiac surgery.

Monitoring of 2D strain of right ventricle free wall by TEE in perioperative of cardiac surgery :

In preoperative time After sternotomy After surgery Inclusions of patients elected for aortic valve surgery without coronary diseases or previous RV dysfunction.

Comparison with others echocardiographic parameters of RV evaluation Association with right ventricle insufficiency after cardiac surgery.

Inclusion Criteria:

• patient eligible for aortic valve surgery

Exclusion criteria:

• previous right ventricle dysfunction
• severe coronary disease
