That is because of the technique and application related limitations of the CCA examination, the catheterization related spasm at the coronary ostium
might result in diagnostic mistakes (18).
For the single coronary, an anastomosis using the autologous pulmonary arterial vessel wall to enlarge coronary ostium
can be employed to avoid ostial stenosis of the coronary artery.
There was no coronary ostium
in the right aortic sinus.
Then, the conduit was pressurized with cardioplegia, and the right ventricle was dilated (short clamping of the venous line) to determine the exact position of the right coronary ostium
to the graft.
2,13) As in our patient, when a coronary artery arises from the opposite sinus of Valsalva, the coronary ostium
is often slit-like.
Anomalous location of coronary ostium
at improper sinus
This refers to a coronary ostium
(either left or right) that is at least 1 cm above the sinotubular junction (instead of being at the aortic sinus) (4,7) (Figure 4).
This was caused by either a right subclavian artery that was either tortuous or had an aberrant origin or dilated aortic root making it difficult to manipulate the catheter into the coronary ostium
26%), one of them from the right coronary ostium
, but none requiring surgery.
Four coronary arteries arising from a single coronary ostium
is a rare anomaly that is generally not mentioned in comprehensive reviews of anomalous coronary arterial origin.
