Percutaneous coronary intervention including intracoronary stenting is currently an accepted treatment modality in the treatment of coronary artery disease and is widely performed to treat the patient with multivessel disease with decreased morbidities and less cost compared with conventional coronary rtery bypass grafting(CABG), Repeated interventions due to restenosis even after successful angioplasty are the major disadvantage of the angioplsty especially when the lesion is located inthe left anterior descending artery(LAD) Recently CABG through left anterior small thoracotomy using the left internal thoracic artery to revascularize the LAD territory without cardiopulmonary bypass so called Minimally Invasive Direct Coronary Artery Bypass(MIDCAB) was intrduced and performed with comparable early outcomes. In this regard the integrated approach with percutaneous coronary intervention and minimally invasive direct coronary artery bypass surgery so called 'Hybrid CABG' was suggested to be an effective treatment in suitable patients with multivessel coronary artery disease. We report three cases of Hybrid CABG.

From Octorber 1984 through September 1991, 480 patients underwent percutaneous tra-nsluminal coronary angioplasty and 7 of these[1.4%] required coronary artery bypass surgeries in the emergency base. The principal indications for surgery were coronary dis-sections[n=2], acute coronary occlusions[n=3], and ventricular arrhythmias[n=2]. There were two early deaths and one late death. No patient who developed cardiac arrest and had not been resuscitated before surgery survived the operation. The outcome of surgery was related to the preoperative clinical status of patients.

Background: Previous studies showed differences in healthcare utilization among insurance types. This study aimed to analyze the difference in healthcare utilization for percutaneous transluminal coronary angioplasty inpatients by insurance types after controlling factors affecting healthcare utilization using propensity score matching (PSM). Methods: The 2011 national inpatient sample based on health insurance claims data was used for analysis. PSM was used to control factors influencing healthcare utilization except insurance types. Length of stay and total charges were used as healthcare utilization variables. Patients were divided into National Health Insurance (NHI) and Medical Aid (MA) patients. Factors representing inpatients (gender, age, admission sources, and Elixhauser comorbidity index) and hospitals (number of doctors, number of beds, and location of hospitals) were used as covariates in PSM. Results: Tertiary hospitals didn't show significant difference in length of stay and total charges after PSM between two insurance types. However, MA patients showed significantly longer length of stay than that of NHI patients after PSM in general hospitals. Multivariate regression analysis provided that admission sources, Elixhauser comorbidity index, insurance types, number of doctors, and location of hospitals (province) had significant influences on the length of stay in general hospitals. Conclusion: Study results provided evidences that healthcare utilization was differed by insurance types in general hospitals. Health policy makers will need to prepare interventions to influence the healthcare utilization differences between insurance types.

Since the introduction of percutaneous; transluminal coronary angioplasty[PTCA] by Grunt-zig in 1977, this is widely used in some patients with coronary artery disease and is an effective alternative to surgery for many patients. Indications for emergency coronary artery bypass graft[CABG] after PTCA are prolonged chest pain, worsening of coronary artery obstruction, "current of injury" by electrocardiogram, cardiogenic shock, and in a lesser incidence, ventricular fibrillation, coronary artery dissection[without obstruction], heart block, and intractable cardiac arrest. Recently, we have experienced one case of emergency CABG following unsuccessful PTCA. The patient was 54 year-old male and admitted with complaint of angina pectoris. The routine electrocardiogram revealed within normal limit. The treadmill test revealed severe chest pain after 2 min. exercise. Coronary cineangiogram revealed 95% segmental stenosis of the proximal right coronary artery. Our cardiologist was planned PTCA. During PTCA, severe chest pain and ischemic pattern on electrocardiogram were developed. But they were not relieved even by morphine and nitroglycerin till 90 min. So we performed emergency single coronary artery bypass graft from aorta to proximal right coronary artery with great saphenous vein. The patient had an excellent postoperative recovery and was free from anginal attack. He has shown striking improvement in general status[NYHA functional class 1] during 6 months after operation.operation.

경심근 레이저 혈류 재건술(transmyocardial laser revascularization, TMR)은 현재 허혈성 심질환 환자에게 널리 사용되고 있는 시술인 경피적 관상동맥 확장술(percutaneous transluminal coronary angioplasty, PTCA)과 관상동맥 우회로술(coronary artery bypass grafting, CABG)에 적응이 되지 않는 환자들에게서 단독 치료 방법으로서 자리를 잡아가고 있다. 본원에서는 관상동맥 우회로술 후에 협심증이 재발한 환자 3 례에서 단독 치료로서 경심근 레이저를 사용하였기에 그 경험을 보고하는 바이다.

Coronary artery bypass grafting (CABG) technique has been much developed but CABG under cardiopulmonary bypass has the unavoidable deficits such as generalized inflammatory reaction from cardiopulmonary bypass and myocardial ischemia from aortic-cross clamp. There has been remarkable advancement of CABG without cadiopulmonary bypass. We performed CABG successfully without cardiopulmonary bypass. We performed CABG successfully without cardiopulmonary bypass in two patients with multivessel coronary disease who were failed to intervene with percutaneous transluminal coronary angioplasty. We herein report the two cases.

재협착에 관여하는 인자는 매우 다양하다. 평활근 세포의 증식, ECM의 형성, 혈관벽의 초기 혈전형성, 그리고 혈관 재형성 등이 모든 것들이 재협착의 병인에 기여하고 있다. 환자마다 이런 요소들의 기여정도가 다르며 동일 환자에서도 병변에 따른 기여정도가 또한 다르리라 여긴다. 그러나 아직까지 우리는 외막섬유모세포의 역할, 내피세포의 재생, 증식세포의 계획된 죽음 등 재협착의 기전을 불완전하게 이해하고 있고 따라서 보다 완전한 이해를 통해 효과적인 재협착 예방치료가 시행될 수 있을 것이다.

Purpose: This study was done to examine the effects of heat therapy on low back pain, blood pressure and pulse rate after percutaneous coronary intervention. Method: The participants in this study were 40 patients who were admitted after having percutaneous coronary intervention. The experimental group, 20 patients, had heat therapy and the control group, 20 patients, maintained a supine position for 12 hours after the intervention. Back pain (VAS), blood pressure and pulse rate were measured just after removal of the sheath, and at 2-hour intervals up to 6 hours. Data were analyzed using SPSS 15.0. Results: The experimental group had significantly lower VAS for low back pain (F=23.44, p=.001). However no significant differences were found between two groups for blood pressure and pulse rate. Conclusion: The findings indicate that heat therapy is effective in reducing low back pain in patients who have had percutaneous coronary intervention. Therefore, heat therapy could be used as nursing intervention percutaneous coronary intervention.

신성 고혈압은 소아기 이차성 고혈압의 흔한 원인이며, 그 중 신동맥 협착에 의한 신혈관성 고혈압은 치료 가능한 고혈압의 가장 흔한 원인이다. 신혈관성 고혈압 치료로 최근 경피적 신동맥 혈관 성형술은 비침습적인 방법으로 각광 받고 있다. 저자들은 작은 직경을 가진 신동맥 분지 혈관 협착에 의한 신혈관성 고혈압 소아에서 관상동맥용으로 쓰이는 풍선 카테터를 이용하여 경피적 신동맥혈관 성형술을 성공적으로 시행한 경험을 하였으므로 보고하는 바이다.

배경: 경피적 관상동맥 성형술(angioplasty, translumial, percutaneous coronary, PTCA)은 현재 거의 모든 관상동맥 협착증 환자에서 시도되고 있다. 따라서 PTCA 실패로 인한 치명적인 응급 상황도 나타나고 있다. 이 연구에서는 PTCA의 실패로 응급 관상동맥 우회술이 필요했던 환자의 임상결과를 분석하고자 한다. 대상 및 방법: 1988년 5월부터 2005년 5월까지 총 5,712예의 PTCA를 시행했고 그 중 실패 후 발생한 응급 환자는 84명(1.4%)이었고 이 중 응급 수술이 가능했던 27명(32.1%)을 대상으로 하였다. 환자들의 평균 연령은 $63.7{\pm}8.9\;(46{\sim}80)$세이었고, 그 중 남자가 14명(51.9%)이었다. PTCA 전 진단은 급성 심근경색(12명), 불안정형 협심증(13명), 안정형 협심증(2명)이었다. 결과: PTCA 실패의 원인으로는 새로운 색전에 의한 관상동맥 폐쇄가 4명, 시술 도중 관상동맥 박리가 17명, 관상동맥 파열이 3명, 기타가 3명이었다. 수술이 가능했던 환자들은 6시간 내로 응급수술을 시행했고 그 중 22명은 고식적 관상동맥 우회술(coronary artery bypass grafting, CABG)을 받았고 5명은 off-pump CABG (OPCAB)을 받았다. 평균 사용된 이식편의 수는 $2.58{\pm}0.95$개였다. 수술 환자 중에서는 18.5%의 사망률을 보였다(5/27). 단변량 분석에서는 수술 환자들의 사망률은 좌전하행지 침범유무, 수술 전 쇼크상태, 수술 후 2가지 이상의 수축 촉진제의 사용, 수술 후에도 대동맥 풍선 펌프를 사용한 경우가 통계적으로 유의하게 나타났다. 결론: PTCA는 환자들이 수술에 비해 상대적으로 안전하다고 생각하지만 PTCA 실패로 인한 응급상황이 발생 시에는 매우 높은 사망률을 보이며 관상동맥 우회술을 시행하더라도 수술 사망률 및 수술 부작용이 상대적으로 높다. 따라서, 치명적인 합병증이 생길 수 있으므로 신중한 환자의 선택이 요구되며 합병증의 발생 시 적극적인 수술 치료를 준비해야 한다.
