Significats de mitral annulus en anglès

Conclusions: The normal mitral annulus accentuates its saddle shape during systole.

Background: Tissue Doppler imaging of the mitral annulus provides useful information about myocardial function.

Background: The anterior mitral annulus is considered a fixed structure.

Standard 2D, Doppler, and mitral annulus pulse wave tissue Doppler were used for all measurements.

Isovolumic acceleration was assessed in the lateral mitral annulus.

The reshaping of the mitral annulus provided by this technology should benefit all patients having mitral repairs.

The LCI was defined as the coapted leaflet length divided by the anteroposterior diameter of the mitral annulus.

Decalcification and reconstruction of the mitral annulus is an established technique, but it is time consuming and technically demanding.

The anterior line was deployed between the anterolateral mitral annulus and the ostium of the left superior pulmonary vein.

Doppler signals from the mitral inflow, pulmonary venous flow, and DTI indices of the lateral mitral annulus were obtained.

Methods: This is a retrospective study of 282 consecutive patients with calcification in either the aortic valve or mitral annulus.

This feasibility study demonstrates the possibility to reshape the mitral annulus on beating heart to precisely increase MV leaflets coaptation height.

In the mitral annulus, strain was also uninfluenced by preload alterations, whereas the peak systolic velocities seemed influenced by preload reduction.

This investigation sought to determine the feasibility of a novel mitral ring designed to reshape mitral annulus on beating heart, after surgery.

Ablation was started at posterior mitral annulus and continued up to left inferior pulmonary vein (LIPV) ostium using an irrigated-tip catheter.

These results demonstrate that mitral valve replacement in patients with a disrupted mitral annulus can be successfully accomplished with a collar-reinforced prosthetic valve.
