The coronary artery cross sectional area (CSA) is proportional to LV mass. We have measured the cross sectional area of the left and right coronary arteries in patients with ischemic heart disease to see whether it is related to the change in the LV mass. The following results were obtained ; 1) There were no significant difference in mean CSA of coronary arteries and LV mass determined by echocardiography and cineangiography between control and ischemic heart disease. 2) There were significantly increased ratio of left ventricular mass by cineangiogram to CSA of left anterior descending coronary artery in patients with myocardial infarction as compared with control group. 3) A linear relation between LV mass by cineangiogram and CSA of left coronary artery was noted in control group (r=0.53, P<0.05) and ischemic heart disease group (r=0.51, P<0.05). 4) A linear relation between LV mass determined by echocardiography and CSA of left coronary artery was noted in control group (r=0.55, P<0.05).

BACKGROUND AND METHOD: For decades, the presence of aortic insufficiency (AI) has been considered a potential hazard in military aviation and has generally excluded aircrew from high performance flight. The cardiovascular effect of repeated exposure of high +Gz forces associated with AI is largely unknown. To evaluate whether the flying of High Performance Aircraft (HPA) was detrimental to subjects with AI, we performed a retrospective review. we studied 32 asymptomatic patients in whom 16 of them had flying time with AI in HPA(Group I), others(GroupII, Control Gr.) in Low-G Aircraft(LGA). Among them, the data of 24 patients were available, 12 in group I., and 12 in group II. The two groups were matched for age, severity of AI, and flying time. RESULTS: Interval echocardiographic, and cineangiographic studies were obtained over a mean period of 4.6+/-2.6 years in group I and 5.9+/-4.2 years in group II (range, 0.9 to 12.7 years) and mean flying time with AI of 528.1+/-435.0 hours in group I and 865.0+/-816.1 hours in group II (range, 50 to 2290 hours). By paired-t test, there were no significant differences between both groups in left ventricular end-diastolic dimension (LVEDD), end-systolic dimension (LVESD), aortic dimension (Ao.D) and fractional shortening (FS) by echocardiography (p>0.05) and by multiple linear regression, there were no significant interval changes of above values in Gr. I according to increasing of flying time with AI (p>0.05). Visual grade by doppler echocardiography or aortic cineangiography increased 1 patient in Gr.I and 2 patients in Gr.II within no more than one grade. CONCLUSION: Thus, this study demonstrated that : 1) Quantitative echocardiographic measurements such as LEVDD, LVESD, Ao.D and FS didn't show significant interval change in Gr.I.2) A single subject with a minor increase in AI severity together with no difference between the HPA and LPA groups argue for a relatively chronic effect of high G exposure in aircrew with mild AI.

Regional left ventricular dysfunction is common in patients with coronary artery disease and accurate analysis of regional dysfunction is of particular interest. For the quantitative assessment of regional dysfunction, we measured regional ejection fraction by radial sector division method in 19 patients with acute myocardial infarction and 13 normal controls who had multigated blood pool scan. And two independent observer analyzed regional wall motion using 5 point grading system in 18 patients undergoing radionuclide ventricular cineangiography. The results obtained were as follows : 1) Regional wall motion scores for the gated blood pool study agreed completely in 72 of 108 segments (66.7%) and agreed within 1 grade in 88 of 108 segments(81.5%) and agreement rate is lowest in the septal area. 2) Global left ventricular ejection fraction was 63.2+/-4.2% in normal controls, 36.6+/-6.8% in extensive anterior wall infarction group and 52.6+/-9.7% in inferior wall infarction group. The value of extensive anterior wall infarction group was significantly lower than that of inferior wall infarction group(p<0.005). 3) Regional left ventricular ejection fraction by radial sector division method in normal control group were as follows : area 1 ; 56.5+/-6.7%, area 2 : 77.9+/-4.8%, area 3 ;84.3+/-5.5%, area 4 : 76.8+/-6.6%, area 5 ; 84.7+/-7.6%, area 6 ; 85.9+/-11.2%, area 7 ; 75.5+/-12.3%, area 8 ; 74.9+/-14.0%, area 9 ; 75.5+/-8.8%, area 10 ; 54.2+/-11.0%, 11 ; 34.5+/-16.3, area 12 ; 37.1+/-18.0%. 4) Mean regional ejection fraction in 7 patients with anterior wall infarction showed significantly lower values in area 4 to area 8, and in area 2 to area 5 in case of inferior wall infarction group. 5) We thought that regional ejection fraction obtained by radial sector division method is valuable index for the management and evaluation of patients with coronary artery disease.

We performed a reoperation of failed tricuspid mechanical valve in a 63-year-old female patient because the overgrown endothelial pannus had entrapped the prosthetic leaflets. Four years ago, the patient underwent mitral and tricuspid valve replacements with 31 and 33 mm Carbomedics, respectively. The patient showed symptoms of neck vein distention, abdominal distention and peripheral edema. The chest film, echocardiography and cineangiography confirmed the diagnosis of tricuspid valve. During the operation, we found the entrapped leaflets of the tricuspid valve in a partially closed state and the endothelial pannus had overgrown into the leaflets. Carpentier-Edward bovine pericardial valve was inserted and the patient was discharged with no significant events.

One family with asymmetric septal hypertrophy was reported. The propositus of this family was 31 years old man who was admitted because of transient syncope. His father and one brother were affected but asymptomatic. His sister was suddenly died at age 21 years. The interventricular septal thickness to left ventricular posterior wall thickness ratios were measured using M-mode echocard ogram. In the affected family, echocardiogram revealed asymmetric septal hypertrophy (1.5:1, 2:1, 1.9:1 respectively). In the propositus, cardiac catheterization and simultaneous biventricular cineangiography were performed. Pressure study revealed mild peak systolic pressure gradient within left ventricular apex and left ventricular outflow tract (4mm Hg respectively). Biventricular cineangiogram showed the septal width increased inferiorly, and left ventricular endocardial surface of the septum was straight, while the right ventricular border convex toward the right ventricle.

BACKGROUND AND OBJECTIVES: Coronary angiography (CAG) is the gold standard for diagnosing coronary artery disease. However, exposure to ionizing radiation delivered during CAG has various negative biological effects on humans. In this study, there was an evaluation of whether fluorography resulted in decreased radiation exposure, as compared with cineangiography. SUBJECTS AND METHODS: Fifty-five patients were prospectively enrolled and divided into two CAG groups, in accordance with the operator's professional discretion: a conventional cineangiography group versus a fluorography group. Fluorography refers to the photography of fluoroscopic images that are retrospectively stored, e.g., using the "Store fluoro" function of the Siemens cardiac angiography system. The primary outcomes included the air kinetic energy released per unit mass {air kerma (AK) mGy} and the dose (kerma)-area product (DAP; microGy . m2), both measured using built-in software in the Siemens system. The secondary outcomes included the total procedure time and amount of contrast agent used with each CAG method. RESULTS: The total AK and DAP were significantly lower in the fluorography group (159.3+/-64.9 mGy and 1337.9+/-629.6 microGy . m2, respectively) than in the cineangiography group (326.9+/-107.5 mGy and 2341.1+/-849.9 microGy . m2, respectively; p=0.000 for both). The total procedure time (cineangiography vs. fluorography, 12.8+/-4.7 vs. 12.5+/-2.9 min; p=0.779) and contrast agent amount (136.1+/-28.3 vs. 126.3+/-25.7, p=0.214) were comparable between the two groups. CONCLUSION: Fluorography is a useful method to decrease the radiation exposure in selected patients requiring CAG.

BACKGROUND: Evaluation of left ventricular (LV) size and function is one of the important reasons for performing echocardiography. Real time three dimensional echocardiography (RT3DE) is now available for a precise non-invasive ventricular volumetry. Aim of work was to validate RT3DE as a non-invasive cardiac imaging method for measurement of LV volumes using cardiac angiography as the reference technique. METHODS: Prospective study on 40 consecutive patients with tetralogy of Fallot (TOF) referred for cardiac catheterization for preoperative assessment. Biplane cineangiography, conventional 2 dimensional echocardiography (2DE) and RT3DE were performed for the patients. A control group of 18 age and sex matched children was included and 2DE and RT3DE were performed for them. RESULTS: The mean LV end diastolic volume (LVEDV) and LVEDV index (LVEDVI) measured by RT3DE of patients were lower than controls (p value = 0.004, 0.01, respectively). There was strong correlation between the mean value of the LVEDV and the LVEDVI measured by RT3DE and angiography (r = 0.97, p < 0.001). The mean value of LV ejection fraction measured by RT3DE was lower than that assessed by 2DE (50 ± 6.2%, 65 ± 4.6%, respectively, p value < 0.001) in the studied TOF cases. There was good intra- and inter-observer reliability for all measurements. CONCLUSION: RT3DE is a noninvasive and feasible tool for measurement of LV volumes that strongly correlates with LV volumetry done by angiography in very young infants and children, and further studies needed.

A 6-year old girl was diagnosed as atrophoderma vermiculatum on face, especially on cheek and preauricular area, and dorsum of both hands. She had suffered from congenital heart disease which was diagnosed as ventricular septal defect by cardiac: catheterization and cineangiography in final. Three months after patch repair of ventricular septal defect, no further new skin lesion developed. But reticulate skin atrophy was remained.
