A study to validate the method based on DIMOND quality criteria for cardiac angiographic images.

A method based on image quality criteria (QC) for cine-angiography was developed to measure the quality of cine-angiograms (CA). A series of 30 CA for left ventriculography (LV) and left and right coronary angiography (LCA, RCA) have been scored and 172 readings were obtained. Standard deviation of quality scores indicated the reproducibility of the method. Each part of CA was examined separately, giving scores for LV, LCA and RCA and a total score (TS), with clinical (C) and technical (T) criteria defined and examined separately. In 83% of the studies TS was >0.8 and with standard deviation from 0.02 to 0.21. In general, LV had a lower score and greater disagreement compared with RCA and LCA. Disagreement was greater in T, compared with C. In conclusion, these results indicate that QC, translated into a scoring system, yields reproducible data on the quality of cardiac images.

Relation of left ventricular sphericity to 10-year survival after acute myocardial infarction.

After ST-elevation myocardial infarction, the association between left ventricular sphericity (measured by biplane ventriculography) and survival rate at a median of 6.5 years was determined in 825 patients. The highest tertile of sphericity (vs the lowest and middle tertiles) was associated with a decreased 10-year survival rate in patients who had anterior myocardial infarction (p = 0.002), inferior myocardial infarction (p = 0.011), Thrombolysis In Myocardial Infarction (TIMI) grade 3 flow (p = 0.005), or TIMI grade 0 to 2 flow (p = 0.001) in the infarct artery. The independent multivariate predictors of a 10-year survival rate were ejection fraction (p = 0.002), treadmill exercise duration (p = 0.004), biplane left ventricular sphericity index (p = 0.032), age (p = 0.043), and end-systolic volume index (p = 0.047), but not TIMI flow grade.

Angiographic morphologic characteristics in pulmonary atresia with intact ventricular septum.

OBJECTIVE: To determine the morphological and functional changes in the right ventricle in pulmonary atresia with intact ventricular septum (PAIVS) for assessing the candidates for the different therapeutic procedures currently available. METHODS: Thirty-one patients underwent cineangiocardiographic study with axial projections. Their ages ranged from 1 to 50 days (x = 9.6), and 28 of them were studied during the first month of life. The statistical analysis comprised the following: chi-square test, Kruskal-Wallis test for the mean and standard deviation, multiple regression, and the 95% confidence interval (95%CI) was calculated. The significance level adopted was alpha < or =0.05. RESULTS: The patients were divided into 3 groups according to the angiographic morphology of the right ventricle (RV): group A -- tripartite RV (n=16); group B -- bipartite RV (n=9); and group C -- unipartite RV (n=6). The diameter of the tricuspid valve was 10.28 +/- 2.67 mm (A); 7.82 +/- 3.41 (B); and 5.27 +/- 0.57 (C) (P=0.0005). Pulmonary atresia was of the valvular type in all group A patients and of the infundibular type in all group C patients (P<0.0001). Coronary-cavitary connections were rare (2/16) in group A patients, but occurred in all group C patients (P=0.0006), with retrograde opacity of the aorta (flow from the RV to the aorta) in 2 group A patients and in all group C patients (P=0.0003). Three patients (2 in group C and 1 in group A) had right-ventricular-dependent coronary circulation. Isolated moderate/severe tricuspid regurgitation showed a tendency towards being more frequent in group A (P=0.0525). The angle of the ductus arteriosus with the descending aorta was as follows: 104.06 +/- 8.98 in group A; 79.17 +/- 33.08 in group B; and 39.0 +/- 6.52 in group C (P=0.0016). The correlation between the diameter of the tricuspid valve and the angle of the ductus arteriosus with the descending aorta was 0.6568 (P=0.0002). CONCLUSION: Because of the heterogeneity of the morphology of the RV in patients with pulmonary atresia with intact ventricular septum, knowledge about all these data is required for selecting candidates for the different therapeutic procedures.
