Significats de residual shunting en anglès

Conclusions: These results suggest that ongoing spontaneous resolution of residual shunting occurs after device insertion.

In 12 patients, a second device was inserted because of residual shunting noted during follow-up.

Factors related to the defect or device could not predict eventual resolution of residual shunting.

There was no residual shunting at the end of the procedure in 75% of the patients.

Transthoracic echocardiography in the follow-up of these patients may not be reliable in determining presence of residual shunting.

We evaluated several variables derived from clinical features, transesophageal echocardiography and catheterization to establish predictors for residual shunting.

This technique is effective in permitting diagnostic and therapeutic left heart catheterization and does not result in residual shunting through the patch.

One patient had residual shunting by transesophageal echocardiography immediately after surgical closure compared with 29 after a mean follow-up of 10 months after device occlusion.
