Pulmonary autograft (PAG) annulus and sinus diameters (mm) measured with transthoracic echocardiography (TTE) during follow up
| Annulus (SD; range) | p Value | Sinus (SD; range) | p Value | |
|---|---|---|---|---|
| A t test with paired variables was used for the difference of the mean PAG diameters at different time points. The relation of PAG annulus and sinus diameter increase with the severity of aortic regurgitation at last TTE was tested by a t test, dividing the patients into two groups according to the semiquantitative measurement of AR (none, trivial and mild versus moderate and severe). | ||||
