    Abstract:
    Correlations between left ventricular segmental kinetics and collateral circulation patterns were studied in 292 patients with coronary disease (182 women, 274 men: mean age 54 years). Left ventricular segmental kinetics were analyzed qualitatively by angiography (10 segments were individualized on RAO and LAO projections) and rated as normal, hypokinetic, akinetic or aneurysmal. The type of collateral circulation observed (contralateral, homocoronary and homolateral) and the number of collateral vessels were recorded. Collateral circulation was present in 49 p. 100 of the patients and in 29 p. 100 of the 587 pathological arteries (i.e. more than 50 p. 100 stenosis) identified. 89 p. 100 of the occluded arteries were revascularized by collateral circulation, the latter being effected by 213 collateral vessels (mean: 1.41 +/- 0.36 vessel per occluded artery). Collateral circulation through 1, 2 or 3 collateral vessels was noted in 62 p. 100, 35 p. 100 and 3 p. 100 respectively of the cases. Collateral circulation was contralateral in 51 p. 100, homocoronary in 33 p. 100 and homolateral in 16 p. 100 of the cases. Normal or hypokinetic segments in the territory of an occluded artery were more frequent in the presence (43 p. 100) than in the absence (31 p. 100) of collateral circulation, but the difference was not significant. They were also more frequent in three-vessel patients (59 p. 100) than in one-vessel (21 p. 100; p less than 0.01) or two-vessel (37 p. 100; p less than 0.05) patients in the presence of collateral circulation.(ABSTRACT TRUNCATED AT 250 WORDS)
