Purpose To research the utilities of a cardiac 64MDCT to a patient who suffered from a chest pain, and to examine a relation between the chest pain and cardiovascular disease by analysing a sort of disease. Materials and Methods During October 2006 to January 2007, we had examined 247 patients (Male : 128, Femal e : 119) who visited our chest pain clinic. We checked patient’s respiration, non-arrhythmia, and low heart rate (75bpm: beat per min) before the examination. Also we excluded the patients from this group who was not in this condition. Results As a result, we found out that there are two groups. Normal group has 77 people (Mal e : 44, Female 33), Abnormal group has 170 people(Male 95, Female 75). The rest 19 people could not be shown an accurate result cause of appearing of potential arrhythmia and growing of the hear rate by respiration fail. We could see the calcification in the coronary artery among the patients. Conclusion From this examination, we could analyze the relation between the chest pain and the cardiovascular, and we were able to know an accuracy and usefulness of the 64MDCT for cardiovascular disease. But arrhythmia and non-controlled respiration are still remained as a limitation of the 64MDCT. Furthermore, to execute an accurate examination of heart without the limitations, more developed-equipment will be recommended.

N/A To test the applicability of Doppler echocardiography in the evaluation of prosthetic valve function, 22 patients in whom the prosthetic valve had been replaced in the mitral and aortic position were examined. The results were as follows: 1) For mitral prosthesis, peak velocity was 155.4±34.90cm/sec, the peak pressure gradient was 9.6±3.40 mmHg, and the mean pressure gradient was 4.0±2.19 mmHg. The prosthctic mitral valve area calculated by the pressure half time was 2.0+ 0.79 cm. 2) For aortic prosthesis, peak velocity was 200.0±38.33cm/sec, the peak pressure gradient was 16.6±5.65 mmHg, and the mean pressure gradient was 8.12±2.27 mmHg. 3) Mild mitral regurgitation was detected in one patient of mitral valve replacement, and aortic regurgitation was detected in four patients of aortic valve replacement.

Of all the many types of foreign bodies which may enter the upper gastrointestinal tract, some may cause serious complication while they are spontaneously passed. But objects longer than 10.0 cm and thicker than 2.0 cm tend to lodge in the stomach, duodenojejunal flexure, ileocecal valve and anus. We experienced a case of spontaneously passed long esophageal stent (13.0 * 2.5 cm in size), which was inserted because of lower esophageal stricture by extension from cardiac cancer of the stomach, after chemotherapy. So, we report this case with the review of the literature.
