Abstract Background— At the mitral annulus–aorta (MA-Ao) junction, the left atrium is continuous through the subaortic curtain with the musculature of the anterior mitral leaflet. Under experimental ...

The Pathology of HLHS The infant with HLHS has a left ventricle which is completely unable to pump oxygen-rich blood reaching the left atrium to the rest of the body through the aorta.

Figure 1. A: fistula between the noncoronary sinus of the aorta and left atrium. Aortography in lateral projection (90° LAO); only the aorta and left atrium are filled in these initial images. B: ...

The left atrium was greatly enlarged and disclosed marked systolic pulsation. Extensive calcification appeared to involve both the aortic and mitral valves (Fig. 3).

The right cusp of the aortic valve was flail and the perforation of non-cusp causing torrential eccentric aortic regurgitation. The aortic annulus just below the aortic valve involving the anterior ...

Mitral valve prolapse occurs if the cusps of the bicuspid valve do not close properly and bulge into the left atrium. For severe cases, treatment may include valve repair or replacement.

Pressures in the left side of the heart may be determined by several methods. The left atrium can be punctured by a needle passed percutaneously either from the posterior chest wall 2–4 or from ...

In particular, a giant left coronary artery aneurysm that connects by fistula to the right atrium accompanied by a ruptured aortic sinus aneurysm (RASA) has been rarely reported. Notably, even ...
