Purpose : This study was designed to investigate normal domestic values for the diameter of the left main coronary artery (LCA), the left anterior descending coronary artery (LAD) and the right coronary artery (RCA). These data are necessary to define dilatation of coronary arteries in Kawasaki disease cases. Methods : Study subjects were 43 normal healthy children whose ages ranged from 3 months to 6 years. They children visited Konkuk University hospital for echocardiograph examination between March 2005 and November 2007. Measurements of coronary arterial diameters at each branch were done by off-line analyses of recorded images. Simple regression analysis of each the measurements were performed using the body size (body surface area, etc.) as the independent variable. Results : Body surface area was significantly related to the diameters of LCA ($r^2=0.20$, P=0.0038), of LAD ($r^2=0.41$, P<0.0001), and of RCA ($r^2=0.30$, P=0.0002). In the regression model, the estimates of the y-intercept were 1.703, 1.058, and 1.007; the estimates of the regression coefficient were 0.971, 1.175, and 1.177; and the estimates of the standard deviation were 0.315, 0.221, and 0.282 with respect to the three coronary arteries. Conclusion : A the linear regression model of the diameters of three coronary arteries adjusted for body surface area was produced. With these results, the Z-score calculation of the diameter of three coronary arteries, based on normal domestic data, will be possible.

Anomalous origin of right coronary artery from pulmonary artery is a rare congenital cardiac anomaly. Anomalous right coronary artery often be a incidental finding without serious cardiovascular sequale. The only characteristic physical finding is a continuous murmur with diastolic accentuation. There are no diagnostic EKG or chest X-ray changes. Diagnosis is made best by selective left coronary arteriography showing retrograde filling of right coronary artery from collateral vessels. Here, we present a case of twenty-four months old aged girl with anomalous origin of right coronary artery combined with pulmonary stenosis. This is the first pediatric patient with anomalous right coronary artery and the first patient to have surgical correction for this malformation.

Bilateral coronary artery to pulmonary artery fistulas are very rare anomaly. Echocardiography, cardiac catheterization and coronary angiography of two patients having chest pain and dyspnea showed bilateral coronary to pulmonary artery fistulas. One patient had left anterior descending coronary artery stenosis and the other patient had cystic tumor. We report the good results of the surgical treatment of two patients with bilateral coronary to pulmonary artery fistulas.

We report a case of the successful anatomical correction of the Taussig-Bing anomaly associated with the interrupted aortic arch and intramural left coronary artery for an 38 day-old infant Aortic arch and neoaortic reconstructions were conducted without any prosthetic or pericardial patch. Intramural left coronary was separated from right one after partial detachment of aortic commissure and both coronary artery buttons were transferred separately to the proximal main pulmonary artery(nee-aorta). Delayed sternal closure was done 3 days after the operation and hospital discharge was delayed for a month because of postoperative pneumonia. Now he is 5 months old and free of symptoms and cardiac drugs.

Use of the left internal thoracic artery(ITA) to bypass the left anterior descending(LAD) coronary artery has become the standard of care based on its superior graft patency, reduced cardiac events, and enhanced survival. But rarely we encountered with injury to the artery during harvesting which leads to loss of the merits of surgery. We reconstructed inadequate ITAa with other arterial conduits so proximal stump to be a blood source if possible. Maternal and method: Between January 1996 and March 1999, 12 patients received bypass with the reconstructed left internal thoracic artery grafts to left anterior descending artery because of an injury(n=8), short or small(n=4). Right or left ITA was used to LAD as a free graft(n=2). And the other 10 left ITAs were extended with radial artery(n=6), right ITA(n=3), saphenous vein(n=1). Composite "T" graft was made with other arterial conduits in these extended graft(n=5). Result: There was only one morbidity of minor would problem, and no mortality. The patency of extended graft to LAD was complete in 5 patients who received angiography during the period of 2wks to 2 years postoperative, but one of side branch of "T" graft occluded. All of these patients were well. Conclusion: Reconstructive extension with the use of other arterial conduit for the injured proximal ITA is warranted in any patients with acceptable results. acceptable results.

From Nov. 1987 to Aug. 1989, 12 patients with coronary occlusive disease underwent coronary bypass surgery at the Department of Thoracic and Cardiovascular Surgery, Catholic University Medical College. The results were as follows: 1. There were 9 males and 3 females ranged in age from 25 to 69 years with a mean of 50.4 years. 2. The prevalent locations of coronary artery stenosis were left anterior descending branch [9 cases], right coronary artery[4 cases], first diagonal branch[3 cases], left circumflex artery [2 cases] in order of frequency. 3, Among 12 cases, 5 cases had an episode of previous myocardial infarction respectively. 4. We performed triple bypass operation in 3 cases, double bypass in 2 cases and single bypass in 7 cases using great saphenous vein. 5. Postoperative complications were cerebral embolism[1, died], pleural effusion[1], temporary cardiac arrest[1], supraventricular tachycardia[1] and late gastric ulcer bleeding[1]. 6. The follow up periods were ranged from 8 months to 30 months and all survivors were on antiplatelet medication showing free of angina.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) has rarely been reported on in adults because 90% of the untreated infants die in the first year of life. We report here on a case of AICAPA that was detected in a 41-year-old woman and she was successfully treated by direct re-implantation of the anomalous coronary artery into the aorta.

We present a patient with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA), which was diagnosed and corrected in her 60 s. The patient is the oldest documented survivor of ALCAPA who underwent a surgical repair. ALCAPA should be corrected surgically to restore the dual coronary system at any age and this case shows that the surgical procedure may be performed safely even in an elderly patient.

We report the case of a female patient who underwent late reoperation following endocarditis surgery. The patient first underwent surgery at 22 years of age for endocarditis with aortic and tricuspid insufficiency. She underwent aortic root replacement with a homograft and tricuspid valve replacement with a tissue valve. Coronary artery bypass using the internal thoracic artery and ligation of the left main coronary artery were performed. Ten years later, failure of the homograft and the tricuspid valve developed. In the second operation, the patient underwent a successful Bentall operation and tricuspid valve replacement with a mechanical valve under deep hypothermia and retrograde cold cardioplegia without drainage.

Resting gated blood pool scan was used to derive left ventricular functional changes in normals (N=13, mean age=43) and in patients with coronary artery disease (N=50, mean age=53). Peak filling rates, average filling rates, and ejection fractions were significantly depressed in coronary artery disease. (p<0.0005, each other). And in coronary artery disease with normal ejection fraction (N=21), peak filling rates and average filling rates were depressed also, and peak filling rates of coronary artery disease with normal ejection fraction were abnormal in 61.2% and average fillin rates were abnormal in 71.4%. It appears that (1) resting peak filling rates and average filling rates were sensitive and easily obtainable parameters of the diastolic dysfunction assosiated with coronary artery disease, (2) a significant proportion of coronary artery disease patients without any evidence of abnormal systolic function have depressed resting peak filling rates and average filling rates of the left ventricle.
