  • The unroofed coronary sinus syndrome is a spectrum of cardiac anomalies in which part or all the common wall between the coronary sinus and the left atrium is absent. This defect is part of a developmental complex which includes absence of the coronary sinus and termination of a persistent left superior vena cava in the left atrium. Recognition of this complex is important so that interruption or diversion of the left superior vena cava may be done to prevent subsequent central nervous system complications. Surgical correction uses an intraatrial baffle to divert flow from the left superior vena cava to right atrium and to close the atrial septal defect. This report describes a 7 years old female patient in whom the left superior vena cava was identified preoperatively and the complex [unroofed coronary sinus syndrome, common atrium, mitral valve cleft] recognized at the time of operation. Surgical correction, following repair of cleft mitral valve, utilized a Dacron patch baffle to route the left caval blood to the right atrium and included closure of the atrial septal defect

  • Between July, 1987, and September, 1988, 6 patients with coronary occlusive disease received coronary artery bypass surgery at Kyungpook University Hospital. There were five males and one female whose age ranged from 39 to 64 years[mean 54*8.0 years]. Of the 6 patients, 5 suffered from unstable angina, 1 suffered from stable angina. Selective coronary angiography revealed a significant stenosis of the left anterior descending artery in 6 cases, of its diagonal branch in 1 case, of the right coronary artery in 1 case, the circumflex artery in 1 case, and of its obtuse marginal branch in 1 case. The mode of anastomosis were single saphenous vein graft in 3 cases, single left internal mammary artery graft in 1 case, double saphenous vein graft with sequential anastomosis in 1 case, and left internal mammary artery plus saphenous vein graft in 1 case. Of these, 6 grafts to left anterior descending artery were done. There was no operative death, but perioperative myocardial infarction was happened in 1 case. All survivors were free of angina and discontinuing medical therapy during the follow up period[mean 7.8*5.15 months].

  • 관상동맥 우회로술 때 보이지 않는 좌전하행지의 노출 방법에는 여러 가지가 있다. 특히 심근 내 위치하는 좌전하행지인 경우 보다 표면에 위치하는 근위 관상동맥을 노출하여 내흉동맥편을 문합함으로써 이식편의 우수한 장기 열림을 기대할 수 있다 육안 상 보이는 원위 좌전하행지의 절개창을 통해 삽입한 더듬자로 심장 외막에 가까운 근위 좌전하행지를 쉽게 노출할 수 있는 방법을 보고하고자 한다.

  • The isolated coronary ostial stenosis is rare and a critical lesion which requires urgent surgical intervention. Recently direct angioplasty is assumed as a preferable approach to conventional bypass grafting. From Mar. 1990 to Aug. 1993, six patients underwent direct angioplasty in Sejong Heart Institute. The mean age of 6 patients was 48 years [range 37 to 63 and they consisted with 5 females and one male. All had severe angina [class III or IV of short duration [mean 5.3 months and a low incidence of risk factors. Despite the crucial location of the lesion, most patients had well preserved left ventricular function and normal wall motion. We performed direct angioplasty with autologous pericardium via anterior approach except one patient who underwent direct angioplasty and CABG. One patient died 4 hours after angioplasty probably due to acute coronary dissection. The survived 5 patients maintain normal life without symptoms during 26.2 months follow up [range 5 to 47 months .Our preliminary results suggest that angioplasty of isolated coronary ostial stenosis in highly selected patient can be carried out with good results and relatively low operative risks.

  • We report a case of recurred Takayasu,s arteritis.The patient was 28-year-old female underwent aorto-left common carotid and aorto-left subclavian bypass graft replacement 1 year ago.Unfortunately, she was readmitted because of newly developing angina and both eye claudication severe headache. Aorto-coronary angiogram showed complete obstruction of left common carotid artery ,stenosis of right carotid artery bifurcation and ostial stenosis of right coronary artery.Bilateral carotid arteries bypass graft with great saphenous vein and right coronary artery bypass graft with right internal mammary artery were done at same the time and she discharged after 21 days without any problem.

  • 좌 관상동맥 폐동맥 이상 기시증은 드문 선천성 심기형으로 유아기에 심부전을 일으키는 질환으로서 수술적인 치료를 하지 않을 경우 대부분 치명적인 것으로 알려져 있다 대혈관 전위의 교정술이 보편화되면서 신생아에서 관상동맥 이식에 대한 기술이 발전되어 근래에는 좌 관상동맥을 대동맥에 이식하여 이중 관상동 맥 체계를 만들어주는 수기가 본 질환의 일차 선택 수술법으로 인정되고 있다. 본 교실에서는 심부전으로 입원한 생후 44일된 여아에서 좌 관상동맥 폐동맥 이상 기시증이 발견되어 좌 관상동맥 대동맥 이식술로 치 료하여 좋은 결과를 얻었으므로 문헌 고찰과 함께 보고하는 바이다.

  • 경피적 관상동맥 중재술 시 사용되는 가이드 와이어의 골절은 드문 합병증이다. 골절로 인하여 관상동맥내에 위치하는 가이드 와이어는 혈관 내막 손상과 혈소판의 응집을 촉발하여 혈전 생성을 야기할 수 있다. 좌전하행지에 위치하여 안정 시 흉통을 유발한 가이드 와이어를 성공적으로 제거하고 관상동맥 우회술을 시행하였기에 보고하는 바이다.

  • Catheters are used to measure translesional pressure gradients in the stenosed coronary arteries. Uses of catheters during coronary angioplasty cause flow obstructions. A narrowed flow cross section with catheter effectively introduced a tighter stenosis than the enlarged residual stenoses after balloon angiplasty. Catheters in blood vessels cause pressure gradient rise and blood flow drop during the measurements. In this study, three dimensional computer simulations are conducted to investigate the flow blockage effects due to the catheter obstructions during the coronary angioplasty. The computer simulation models are generated by the data, which are measured by coronary angiogram, and the blood is treated as non-Newtonian fluid. The velocity, pressure, and wall shear stress variations are observed for the estimate of damages of blood vessel. This study is also extended to investigate the effects of stenotic vessel size, and shape and catheter size and location.

  • Recently we experienced coronary artery bypass graft in two patients over 70years of age. Among them, one case was 74 old year male and the other case was 73 old year male. The coronary artery diseases of them were angiographically diagnosed to triple vessel diseases. We only used great saphenous vein as graft vessel in two patients. The postoperative courses were good except mediastinal bleeding in 1 case. They were discharged with good results. They were still healthy 40 months in one and 30 months in the other after coronary artery bypass grafting.

  • Purpose: The study was conducted to find out clinical characteristics for coronary artery disease patients with diabetes mellitus. Methods: We retrospectively reviewed the electronic medical records which included the data of 6,792 patients, who had been diagnosed coronary artery disease (CAD) such as angina or acute myocardial infarction and admitted to a university hospital in Seoul from January, 2005 to November, 2010. Results: Of the 6,792 patients, 43% had been diagnosed diabetes as comorbidity. The CAD patients with diabetes had lower left ventricular ejection fraction, stayed longer at hospital, and spent on more time from the first symptom to hospital visit than those without diabetes. In addition, they were more likely to have multi vessel coronary artery disease. Conclusion: The CAD patients with diabetes lay on the various factors which can make more worsen condition. Hence, we need to pay attention to specialized nursing care and patient education for the CAD patients with diabetes.
