  • Background: The safety and efficacy of arterial composite grafts for total arterial revascularization have been demonstrated. The saphenous vein (SV) is a widely used graft because of its accessibility, sufficient length, and ease of manipulation. Our aim was to compare mid-term outcomes of saphenous vein Y-grafts with radial artery Y-grafts joined by anastomosis to the left internal thoracic artery. Materials and Methods: Records of off-pump coronary artery bypass grafting with composite Y-grafts based on the left internal thoracic artery technique in 552 patients were analyzed retrospectively. After propensity score matching, 79 radial arterial (RA) composite grafts (RA group) and 79 saphenous vein composite grafts (SV group) were compared. The duration of mean follow-up was $24.6{\pm}14.6$ months (range, 1 to 55 months). Results: There were no differences in surgical mortality, all-cause mortality, or morbidity among the groups. Rates of 4-year survival were 91.7% and 96.3% in the RA and SV groups, respectively (p=0.519). The coronary reintervention-free survival rate and freedom from major adverse cardiovascular or cerebrovascular events were similar in the two groups (p=0.685, p=0.564). Conclusion: Construction of composite Y-grafts using the radial artery or saphenous vein showed similar mid-term results. Long-term follow-up and randomized trials will be needed to confirm our present conclusions.

  • Left main coronary artery (LMCA) thrombosis is rare and the cause should be determined. A previously healthy young man presented with severe chest pain and dyspnea. The electrocardiogram showed typical ST-segment elevation myocardial infarction with clinical instability. Emergency coronary angiography revealed complete LMCA occlusion by thrombosis. After reperfusion, the patient was admitted to the cardiac care unit. He was diagnosed with hemolytic anemia and tested positive for antinuclear antibodies. Systemic lupus erythematosus (SLE) and LMCA disease due to systemic thrombosis were diagnosed. Steroids were started and the patient was discharged without complications. We report this rare case of LMCA thrombosis as an initial presentation of SLE.

  • A coronary artery fistula was surgically ligated in a 38-year-old woman via a left anterior mini-thoracotomy without the use of cardiopulmonary bypass. In selected cases, this surgical approach can provide an excellent surgical exposure for coronary artery fistula ligation. It also offers an excellent cosmetic result and shorter hospital stay.

  • A 8-year-old boy underwent surgical correction of complete transposition S.D.D. of great arteries combined with subaortic ventricular septal defect and pulmonary stenosis [infundibular and valvular]. The operation consisted of an internal baffling connecting the left ventricle to the aorta through the ventricular septal defect. The pulmonary stenosis was corrected with the method of external connection, the right ventricle to the pulmonary artery using the conduit valve [20 mm] contained Hancock due to abnormal distribution of left coronary artery of which conduit due to abnormal distribution of left coronary artery of which the circumflex branch crossed the portion of right ventricular outflow tract. This case was suitable for corrective surgery-Rastelli operation-and the patient`s condition in very good until present [post-operative 5 months].

  • 배경: 관상동맥에 내흉동맥편과 복재정맥편을 동시에 문합할 때 두 이식편 사이에 생기는 혈압과 혈류의 차이 때문에 내경이 작은 내흉동맥편의 개존이 나빠질 수 있다. 이런 수술을 받은 환자에서 중단기적 임상 결과를 보고 특히 상경적인 혈류의 영향을 많이 받는 내흉동맥편의 개존 상태를 알고자 하였다. 대상 및 방법: 좌전하행지에 문합된 내흉동맥의 혈류가 충분하지 못하다고 판단된 14예의 환자에서 같은 관상동맥에 좌내흉동맥편과 복재정맥편을 동시에 문합하였다. 평균 33.5개월의 추적기간동안 증상이 재발한 경우, 좌내 흉동맥편의 혈류를 확인하고자 하는 경우, 수술 직후에 Q파를 보인 경우 등 6예에서 관상동맥 조영술을 시 행하였다. 결과: 복재정맥편과 내흉동맥편은 모두 개존되어 있었으며, 2예에서는 양측 균등한 혈류를 보인 반면, 다른 2예에서는 상경적인 혈류를 보였고 나머지 2예에서는 내흉동맥편이 개존되어 있었으나 관상동맥 으로 가는 혈류는 거의 없었다. 결론: 좌내흉동맥편을 좌전하행지에 문합하는 수술에서 복재정맥편을 부가 적으로 좌전하행지에 문합하는 경우에 수술 후 좌전하행지의 혈류를 충분히 유지할 수 있으며, 이러한 이중 문합이 내흉동맥편의 중단기적 개존에 영향을 미치지는 않을 것으로 생각된다.

  • Background and Objectives: Feasibility of coronary angiography (CAG) and percutaneous coronary intervention (PCI) via left snuffbox approach is still concerned. We aimed to investigate efficacy and safety of the left snuffbox approach for CAG and PCI. Methods: Left snuffbox approach was tried in 150 patients who planned to perform CAG or PCI for suspected myocardial ischemia between 1 November 2017 and 31 March 2018. Results: Success rate of radial artery (RA) cannulation via snuffbox approach was 88.0% (n=132). Among 132 individuals, 58 (43.9%) acute coronary syndrome (ACS) patients were included. The diameter of snuffbox RA was significantly smaller than conventional RA (2.57 mm vs. 2.72 mm, p<0.001) from quantitative computed angiography of 101 patients. However, CAG via snuffbox approach by 6 French sheath was successfully performed in all 132 patients. In addition, there was significant correlation between the snuffbox and conventional RA diameter (r=0.856, p<0.001). In 42 PCI cases, including 25 patients with acute myocardial infarction (AMI), the success rate of PCI via snuffbox approach was 97.6% (n=41). Intravascular imaging-guided PCI was performed in 8 (19.5%) patients and multi-vessel PCI in 4 (9.8%) cases. Regarding vascular complication, forearm swelling with bruising, not requiring surgery or transfusion, occurred in 2 (4.9%) PCI cases. Conclusions: Left snuffbox approach is suitable for CAG and PCI compared with the conventional radial approach.

  • We have anlayzed the polar maps of dipyridamole stress/rest $^{99m}Tc$-MIBI SPECT and compared the quantitated perfusion defects of dipyridamole stress polar map and the findings of coronary angiography in 56 pateints with coronary artery diseases. We performed the same day dipyridamole stress-rest myocardial SPECT, reconstructed the polar maps according to Cedars-Sinai method and quantitated perfusion detects of total myocardium and the territory of each artery, comparing the polar maps of patients with normal files. Stenosis more than 50 percent was considered significant and myocardial ischemic score was calculated as summed score of percents of main coronary arteries. Positive concordance of myocardial SPECT with coronary angiography were 82.6% with left anterior descending artery (LAD), 85.7% with left circumflex artery (LCx) and 78.6% with right coronary artery (RCA). Perfusion defect of SPECT polar map and the stenosis of coronary artery showed the contingency phi of 0.55 (p<0.0001) with total atreries, 0.38 (p = 0.016) with LAD, 0.50 (p<0.0001) with LCx and 0.40 (p = 0.007) with RCA. Dipyridamole stress percent defect of polar map was correlated with myocardial ischemic score with Spearman's rho of 0.47 (p = 0.001) in total arteries, 0.48 (p=0.001) in LAD, 0.56 (p < 0.001) in LCx and 0.38 (p=0.002) in RCA. These findings revealed that defect of the dipyridamole stress myocardial $^{99m}Tc$-MIBI SPECT and the percent extent of this defect were related with significant artery stenosis of individual arteries and the degree of stenosis. We thought that we could use the defects in the polar map of dipyridamole stress $^{99m}Tc$-MIBI SPECT for the quantification of myocardiasl perfusion decrease.

  • 요골동맥을 이용한 관상동맥 우회 술은 1970년대초 처음 도입되었으나 요골동맥 연축(spasm)에 의한 이식편의 부전으로 사용이 중지되었으나, 1980년대 후반 칼슘 길항제등 새로운 연축 방지제의 개발과 요골동맥 채취방법(harvesting technique)의 개선으로 다시 사용하게 되었다. 저자들은 1994년 10월부터 1995년 7월까지 총 36례에서 요골동맥 자유이식 편을 이용하륵 관상동맥우 회술을 시행하였다. 이들중 34례에서 좌측 내흉동맥을 동시에 사용하였으며 15례(42%)에서는 모든 이 식편을 동맥이식 편으로 사용하였다. 총 123개의 원위부 문합중(환자당 평균 3.4개) 좌측 내흉동맥을 사용한 문합이 36개,복재정맥을 이용한 문합이 23개였으며 나머지 64개의 윈위부 문합은 요골동맥을 사 용하였고(환자당 평균 1.8개), 요골동맥을 이용한 문합이 전체문합수의 52%를 차지하였다. 요골동맥이 식편의 원위부 문합장소는 좌측회선지(circunflex artery)가 38개, 사선지(diagonal artery)가 18개, 우측 관상동맥이 6개, 좌전하행 지(left anterior descending artery)가 2개로 분포하였다. 요골동맥을 하나의 이 식편으로 사용한 경우가 10례, 순차적문합으로 사용 \ulcorner경우가25례 및 두개의 이식 편으로 나누어 사용 한 경우가 1례였다. 관상동맥 우회 술과 동반된 수술로는 관상동맥 내막절제술이 14례, 관상동맥 포편성 형술(patch angioplasy)이 4례, 승모판막 재건술이 1례, 심근경색후 심실중격파열 봉합술이 1례였다. 수 술후 합병증으로는 요골동맥을 채취한 측의 엄지손가락 감각이상이 2례, 술후 출혈이 1례,저심박출증 으로 좌심실보조장치 1례등이 있었으며 이중 좌심실보조장치를 시행한 1례에서 사망하였다. 조기추적 관상동맥 조영술은 생존한 35례중 11례(31%)에서 수술후 79일에서 210일(평균 126일)에 시행하여 좌측 내흉동맥 및 복재정맥은 100%, 요골동맥은 95%의 개방률을 보였다. 생존한 환자 모두에서 협심증의 재 발은 없었다. 결론적으로 본 연구에서는 아직 증례의 부족과 짧은 추적기간으로 요골동맥 이식편의 우 월성은 입증할 수 없으나 단기적으로 만족할만한 것으로 향후 더 많은 경험의 축적과 장기적 인 추적이 요할 것으로 사료된다.

  • 환아는 3개월된 영아로 발병 10일째에 본원에 내원하여 초기에 적절한 진단과 치료를 받지 못했으며 발병 2주에 시행한 심초음파상 거대 관상동맥류를 보였다. 이에 정맥용 면역글로불린 투여와 aspirin과 dipyridamole로 치료 중 발병 24일째 혈전증이 동반되어 urokinase와 heparin의 IV 투여를 통한 혈전용해 치료로 혈전을 완전히 제거할 수 있었다. 이후 5년간 aspirin, dipyridamole, coumadin을 투여하면서 심전도와 심초음파검사를 반복하며 외래 추적 관찰 중 점차 좌측관상동맥내 혈전이 증가하고 내경이 점차 좁아지는 소견과 함께 협착이 의심되었다. 발병 5년 후 시행한 관상동맥 혈관조영술상 관상동맥 좌측 전하지가 완전 폐색되고 우측관상동맥으로부터 발달한 측부순환에서 혈류를 공급받고 있었고, 핵의학 검사상 좌심실의 전벽과 중격, 일부 외벽에 완전 가역적 관류 결손을 보였던 가와사끼병 환아 1례를 경험하여 보고한다.
