ABSTRACT
BACKGROUND AND OBJECTIVES: It has been suggested that the indices based on tissue doppler and color M-mode echocardiography reflect the left ventricular end-diastolic pressure. These include the early diastolic transmitral velocity (E) to early myocardial velocity ratio measured by tissue doppler (E') and the E to the wave propagation velocity (Vp) ratio measured from color M-mode images. However, these indices have not been well validated in congestive heart failure patients. SUBJECTS AND METHODS:Thirty one congestive heart failure patients who underwent simultaneous cardiac catheterization and echocardiography, and had normal sinus rhythm were enrolled in this study. The left ventricular end-diastolic pressure obtained from the left heart catheterization was compared with the diastolic indices using pulsed doppler, tissue doppler and color M-mode echocardiography. RESULTS: The left ventricular end-diastolic pressure (LVEDP) ranged from 3.3 to 23 mmHg. Some parameters showed a significant correlation with the LVEDP. The propagation velocity showed a significant correlation with the LVEDP (r=0.382, p=0.034), and the E to propagation velocity ratio (E/Vp) showed a good correlation with the LVEDP(r=0.408, p=0.023). In addition, the E to early diastolic velocity of the mitral annulus (E') ratio had an insignificant correlation with the LVEDP(r=0.322, p=0.078). Among the patients with ischemic congestive heart failure, the E to the propagation velocity ratio (E/Vp) showed a marginal correlation with the LVEDP (r=0.461, p=0.047). CONCLUSION: In patients with congestive heart failure, the Vp and E/Vp showed a good correlation with the LVEDP. In the subgroup of patients with ischemic congestive heart failure, only the E/Vp showed a significant correlation with the LVEDP.

BACKGROUND: Coronary anomalies are found incidentally, in which anatomy is altered but physiology is normal; that is, coronary blood flow is normal. However, certain anomalies are associated with myocardial ischemia or infarction, heart failure, and sudden death. METHODS: From February 1988 to February 2000, 3534 cases have been catheterized, among them we experienced 28 cases of coronary anomalies. The incidence of coronary anonalies and clinical characteristic were evaluated. RESULTS: The incidence of coronary anomalies was 0.79% and in 28 cases of coronary anomalies, 5 cases of anomalous origin from the aorta (0.14%), 2 cases of coronary artery aneurysm (0.16%) and 21 cases of coronary arteriovenous fistula (CAVF,0.59%) were found. In 5 cases of anomalous origin from the aorta, 4 cases showed that right coronary artery originated from left coronary sinus of Valsalva, 1 case showed that left circumflex coronary artery originated from right coronary sinus of Valsalva. All of coronary artery aneurysm were found in right coronary artery. In 21 cases of CAVF, 28 sites of fistula were found and 14 sites originated from right coronary artery (50%), 6 sites from left circumflex coronary altery (21.5%), 6 sites from left anterior-descending coronary artery, 2 sites from left main coronary artery (7%). 13 sites of CAVF drained into pulmonary artery (46%), 10 sites into right atrium (36%), 5 sites into right ventricle (18%). In 7 cases which had double CAVF, 4 cases were originated from bilateral coronary artery, 3 cases were originated from single coronary artery. In 10 cases CAVF without other cardiac lesion, 4 cases confirmed ischemic heart disease. CONCLUSION: In our study, CAVF is most common coronary anomaly and without other cardiac disease CAVF may develope ischemic cardiac disease.
