  • Myocardial infarction (MI) secondary to coronary artery fistula and the subsequent occlusion of the distal right coronary artery (RCA) after blunt chest trauma is a rare entity. Here, we describe a case of coronary artery fistula and occlusion with an inferior MI that occurred following blunt chest trauma. At the initial visit to the emergency room after a car accident, this patient had been undiagnosed with acute myocardial infarction, readmitted five months after ischemic insult, and revealed to have experienced MI due to RCA-right atrial fistula and occlusion of the distal RCA. He underwent coronary surgery and recovered without complications.

  • Congenital coronary arterial fistulae are the most prevalent hemodynamically significant congenital coronary artery malformations. Definition of congenital coronary arterial fistula is a direct communication between a coronary artery and the lumen of one of the four cardiac chambers or coronary sinus or SVC, pulmonary artery or pulmonary vein close to the heart. It is often associated with additional congenital or acquired heart disease. A 49 year old male patient was admitted with the chief complaints of anginal pain and exertional dyspnea for 9 months. He was diagnosed as the right coronary arterial fistula combined with right coronary arteriosclerotic stenosis and old inferior myocardial infarction by cardiac evaluation. The right coronary arterial fistula was communicated between the just distal portion of acute marginal branch and coronary sinus. The operative procedure was as followings; after suture ligation of fistula opening in the coronary sinus under beating heart, coronary arterial bypass grafting with saphenous vein was performed at the just proximal portion of the posterior descending branch under cardiopulmonary bypass. The postoperative course was uneventful and he was discharged without anginal pain at the 8th postoperative day.

  • Background: This study was conducted to provide a comparison between the clinical outcomes of primary percutaneous coronary intervention (PCI) and that of fibrinolysis followed by routine invasive treatment in ST elevation myocardial infarction (STEMI). Methods: A total of 184 consecutive STEMI patients who underwent primary PCI or fibrinolysis followed by a routine invasive therapy were enrolled from 2004 to 2011, and their major adverse cardiovascular events (MACEs) were compared. Results: Among the 184 patients, 146 patients received primary PCI and 38 patients received fibrinolysis. The baseline clinical characteristics were similar between both groups, except for triglyceride level ($68.1{\pm}66.62$ vs. $141.6{\pm}154.3mg/dL$, p=0.007) and high density lipoprotein level ($44.6{\pm}10.3$ vs. $39.5{\pm}8.1mg/dL$, p=0.005). The initial creatine kinase-MB level was higher in the primary PCI group ($71.5{\pm}114.2$ vs. $35.9{\pm}59.9ng/mL$, p=0.010). The proportion of pre-thrombolysis in MI 0 to 2 flow lesions (92.9% vs. 73.0%, p<0.001) was higher and glycoprotein IIb/IIIa inhibitors were administered more frequently in the primary PCI group. There was no difference in the 12-month clinical outcomes, including all-cause mortality (9.9% vs. 8.8%, p=0.896), cardiac death (7.8% vs. 5.9%, p=0.845), non-fatal MI (1.4% vs. 2.9%, p=0.539), target lesion revascularization (5.7% vs. 2.9%, p=0.517), and stroke (0% vs. 0%). The MACEs free survival rate was similar for both groups (odds ratio, 0.792; 95% confidence interval, 0.317-1.980; p=0.618). The clinical outcome of thrombolysis was not inferior, even when compared with primary PCI performed within 90 minutes. Conclusion: Early fibrinolysis with optimal antiplatelet and antithrombotic therapy followed by appropriate invasive procedure would be a comparable alternative to treatment of MI, especially in cases of shorter-symptom-to-door time.

  • 1967년 Killip 등은 급성 심근 경색의 내과적 치료 결과 27%의 높은 사망률을 발표하였으며 급성 심근경색은 내과적 치료만으로는 사망를이 10%에 달하는 질환으로서 특히 급성 심근경색후 협심증의 경우 이것이 심실성 부정 맥이나 심근경색의 확대 및 좌심실 기능 부전의 전조증상인 경우가 많으며 따라서 적극적인 치료가 필요하다 하겠다. 그러나 과거에는 심근경색환자에 대한 수술 사망률이 높아 심근경색 후 조기에 수술하는 것을 회피하는 경향이 있었으나 최근 심근보호벌 및 수술 수기의 발달로 좋은 성적이 발표되고 있다. 한림대학교 강동성심병원에서는 1994년 6월부터 1996년 10월까지 내원한 급성 심근 경색 환자중 19명을 대상으로 급성 심근경색후 1개월 이내에 조기 관상동맥 우회술을 실시하였다. 환자는 남자가 14명, 여자가 5 명이었으며 이들의 평균 연령은 60.6세였다. 급성 심근 경색후 관상동맥 우회술까지의 기간은 8시간부터 24 일까지로 평균 10.6일이었다. 심근 경색은 전층 경색이 11명, 심내막하 경색이 8 명이었다. 한편 경색 부위는 하벽부가 11예, 전벽 및 중격 부위가 8 예였다. 수술중 원위부 문합은 모두 대동맥을 차단한 후 쳬璿臼느만\ulcorner심근보호는 온혈 심정저택과 냉혈 심정지액을 병행하여 시행하였다. 평균 대동맥 차단시간은 101.7분이었으며 체외순환시간은 225.6분이었으며 환자당 평균 3.6 개의 원위부 문합을 시행하였다. 수술전 IABP를 삽입한 경우는 3예였으며 수술중에는 심폐기 이탈 을 위해서 4명에게 IABP를 사용하였다. 1명의 환자가 수술후 21일째 급작스러운 폐렴 및 호흡부전으로 사망하여 사망률은 5.3%(1/19)였다. 수술후 합병증은 수술주기 심근 경색이 2례, 상심실성 부정맥이 2예있었으며 심실성 부정맥과 폐렴이 각 1례였다. 심실성 부정맥을 보인 환자가 술후 77일째 사망하여 말기 사망률은 5.5%(1/18)이었다. 수술후 추적 기간은 평균 13.4개월로 모두 외래에서 추적 진료 중이며 2년 생존율은 89.5%로 예측되었다. 수술후 사망과 관련된 위험요소로서는 수술전 심박출 계수가 30% 이하인 경우와 수술중 인공 심폐기의 이탈을 위하여 IABP(intra-aortic balloon pump, 대동맥내 풍선 펌프)를 사용한 경우 통계학적 의미를 찾을 수 있었다. 결론적으로 진행성 심근 경색 환자들이나, 지속적인 협심증 또는 심각한 관상동맥 경화증이 의 경우 급성 심근 경색이 발생\ulcorner 직후라도 술전 심박출 계수가 30% 이상 유지될 수 있는 심장 있는 환자에서 선택수술 (elective coronary artery bypass graft)에 비하여 특별한 위험 요소의 증가 관상 동맥 우회술을 적용하여 좋은 결과를 얻을 수 있었으며 이들에 대한 장기 추적이 릴요할 된다.
