The Effect of Collateral Circulation on Segmental Left Ventricular Contraction By ROBYN
نویسنده
چکیده
coronary artery and/or left anterior descending coronary artery. Collateral vessels were identified in 69% of the patients with coronary artery disease (82/119). The cases with collaterals were graded poor, fair, or good according to the number of vessels and the quality of opacification. Segmental contractile motion was determined angiographically by the percent shortening of each of the six chords of the left ventricle in the right anterior oblique projection. The range of normal shortening (mean one standard deviation) for each chord was established in the 43 normal patients as follows:

متن کاملThe effect of cardiac contraction on collateral resistance in the canine heart.
We determined whether the coronary collateral vessels develop an increased resistance to blood flow during systole as does the cognate vascular bed. Collateral resistance was estimated by measuring retrograde flow rate from a distal branch of the left anterior descending coronary artery while the main left coronary artery was perfused at a constant pressure. Retrograde flow rate was measured be...
متن کاملRADIOLOGY Pathways and Functional Significance of the Coronary Collateral Circulation
Two hundred coronary arteriograms and left ventriculograms of patients having significant coronary artery disease were reviewed. Collateral circulation was seen only when the degree of arterial narrowing exceeded 90%. Ten different collateral pathways were noted in patients having right coronary obstruction; seven different pathways were noted in left anterior descending obstruction; five diffe...
متن کاملThe role of collateral circulation in preserving myocardial function.
The coronary collateral circulation is an alternative source of blood supply to the myocardium jeopardized by the failure of the original stenotic or occluded vessel to provide adequate blood flow to this region. One hundred coronary angiograms and left ventriculograms of patients with coronary artery disease from the Cardiology Department of University Clinics Centre in Sarajevo were reviewed....
