  • Postinfarction ventricular septal rupture (VSR) is a rare but fatal complication of acute myocardial infarction. In many cases, postinfarction VSR leads to hemodynamic instability and urgent surgical treatment is necessary. Here we describe a case of a patient with right ventricular (RV) dysfunction caused by acute RV infarction and with cardiogenic shock, whose condition improved after development of postinfarction VSR, but the patient died after corrective surgery.

  • 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.

  • Ventricular septal rupture (VSR) is a rare but lethal complication of myocardial infarction. The event occurs 2~8 days after an infarction and often precipitates cardiogenic shock. Post myocardial infarction VSR is known for difficult to repair. Especially, Transmural myocardial infarction involved in the posterior VSD area, exposure of the affected site is difficult and postoperative mortality rate is high. We have experienced a case of a 75-year-old female patient who suffered posterior VSD due to acute myocardial infarction, and attained good result by approaching the lesion through right atrial incision and repaired the defect by using patch closure technique.

  • Prosthetic valves are being widely used in the treatment of heart valve disease. Prosthetic valve endocarditis (PVE) is one of the most catastrophic complications seen in these patients. In particular, prosthetic valve dehiscence can lead to acute decompensation, pulmonary edema, and cardiogenic shock. Here, we discuss the medical management of late PVE in a patient with a prior history of late and redo early PVE and recurrent dehiscence. According to the present case, we can summarize the learning points as follows. A prior history of infective endocarditis increases the risk of relapse or recurrence, and these patients should be evaluated very cautiously to prevent late complications. Adequate debridement of infected material is of paramount importance to prevent relapse. A history of dehiscence is associated with increased risk of relapse and recurrent dehiscence.

  • A 55-year-old woman who had received an implantable left ventricular assist device 3 months earlier presented with dyspnea and a low-flow alarm of the device. Computed tomography and log-file analysis of the device system suggested inflow cannula obstruction. Since the patient had cardiogenic shock due to pump failure, venoarterial extracorporeal membrane oxygenation (ECMO) was initiated. With ECMO, surgical exchange of the pump was considered. However, the obstruction spontaneously resolved without surgical intervention. It turned out that an obstructive thrombus was washed out by rebooting the pump. Moreover, the thrombus was embolized in the patient's left subclavian artery. The patient underwent heart transplantation 4 months after the pump obstruction accident and continued to do well.

  • Median sternotomy is a standard surgical technique used for left ventricular assist device (LVAD) implantation. However, if sternotomy has a prohibitive surgical risk, LVAD implantation can be performed through only left thoracotomy. We managed a patient with end-stage heart failure who had recently undergone coronary artery bypass grafting (CABG) elsewhere. The patient also had a deep sternal wound infection and bacteremia. Because of refractory cardiogenic shock, we performed extracorporeal membrane oxygenation (ECMO). After multiple mediastinal washouts and omental flap placement, ECMO was converted to extracorporeal LVAD (from the left ventricular apex to the descending aorta) through a left thoracotomy. The extracorporeal LVAD was maintained for 18 days and replaced by the HeartMate 3 LVAD. The patient was discharged in good condition 115 days after CABG.

  • 1994년 6월부터 1996년 8월까지 한림대학교 강동성심병원에서는 총 88례의 관상동맥우회 술을 시행하였 튼데 그중 13례를 응급으로 시행하였다. 응급수술 시행환자의 남녀비는 3:10으로 선택수술의 41:34에 비 하여 여자가 많았으며 나이는 평균 65.5+/-6.3(56-80)세로 선택수술의 58.9+/-10.3(35-82)세와 유의한 차이가 없었다. 응급수술의 적응증은 수회의 심율동전환(cardioversion)에도 반응하지 않는 심실성 빈맥환자 1례를 제외한 12례가 심인성 쇼크였는데 심인성 쇼크의 원인으로는 진행성 심근경색이 6례, 경피적 관상동맥성형술 실패가 4례, 급성 심근경색이 1례, 그리고 급성심근경색후 심실중격파열이 1례를 차지하고 있었다. 13Bl 의 환자중 5례의 환측는 심인성 쇼크가 발생한 후 2시간 이내에 수술을 시작할수 있었으나 나머지 8례의 환자는 3시간 내지 10시간이 지나서야 수술을 시작할수 있었다. 13례의 환자중 12례의 환자에서는 통상의 관상동맥우회 술을 시행하였는데 그중1례에서는 파열된 심실 중격 봉합을 동반시행하였으며 좌주관상동맥에만 국한된 병변이 있었던 1례의 환자에서는 좌주관상동맥 성형술을 실시하였다. 통상의 관상동맥 우 \ulcorner술을 시행한 12례의 환자에서는 37개의 문합을 실시하여 환자 당 평균 3.1개를 실시하였는데 선택적인 수술과는 달리 내흉동맥은 3례의 환자에서만 사용할수 있었으며 나머지는 모두 복제정맥을 이용한 문함을 시행하였다. 수술하는데 필요한 대동맥차단시간은 평군 96+/-25(65-140)분이었으며 인공심폐기 가동시간은 평균 281+/-117(136-592)분으로 손상된 심근의 회복을 위한 심보조시간이 상당부분을 차지하고 있었다. 수술후 5례의 환자가 사망하여(38.5%) 선택수술의 4.0%(3/75)에 비하여 높은 사망률을 보이고 있었으며 사망원인으로는 좌심실기능부전이 3례,심실성 인맥이 1례,그리고 다장기 기능부전이 1례를 차지하고 있 었다. 또한 3례의 환자에서 수술주위 심근경색, 종격동염,그리고 상부위장관출혈, 등의 합병증이 발생하 였으나 별다른 후유증없이 치유되었다. 생존한 환자 8례는 모두 현재 외래에서 특별한 문제없이 추적관 찰중이다. 결론적으로 아직 사망률이 높기는 하지만 심인성 쇼크 등과 같은 중환자들에게서 의 적극적인 치료는 이러한 환자들을 살릴수 있는 유일한 방법이라 생각되며 이러한 치료에 있어서 가장 중요한 점은 심장에 비가역적인 손상이 발생하기 전에 시행하는 조기수술요법이라 생각된다.

  • 배경: 관상동맥 우회술은 가장 안전하게 시행할 수 있는 심장수술로 자리를 잡아왔다. 하지만 심한 관상동맥 질환으로 인한 심인성 쇼크 시 시행하는 응급 관상동맥 우회술은 선택적 수술에 비해 높은 사망률을 보인다. 본 연구에서는 응급 관상동맥 우회술을 시행받은 34명의 중장기 성적에 관하여 알아보았다. 대상 뜻 방법: 1994년 6월부터 2001년 12월까지 한림대학교 강동성심병원에서 시행한 34예의 응급 관상동맥 우회술을 대상으로 하였다. 병록과 외래추적 조사를 토대로 수술전 진단과 위험인자, 수술 전 관상동맥 조영술 소견, 수술방법, 수술 사망률, 수술 합병증, 수술후 증상의 재발과 치료, 만기 사망에 대해 후향적으로 분석하였다. 결과: 응급 관상동맥 우회술의 적응증으로는 심인성 쇼크가 29예(85.3%), 내과적 치료에 반응하지 않는 흉통이 4예(11.8%), 다형성 심실빈맥이 1예(2.9%)였다. 술 전 관상동맥 조영술상 삼혈관 질환이 16예(47.1%)였고, 좌주관상동맥 질환이 8예(23.5%)였다. 수술시 대복재 정맥 81문합, 좌측 내흉 동맥 14문합을 시행하였고, 환자당 평균 문합수는 2.8$\pm$0.8개였다. 평균 대동맥 차단 시간은 평균 91.9$\pm$34.6분이었고, 평균 심폐기 가동 시간은 262.7$\pm$198.3분이었다. 조기 사망률은 50%였고, 가장 많은 사망원인은 수술 후 저심박출증(7예, 20.6%)이었다. 평균 추적조사 기간은 30.9$\pm$35.7개월이었고, 추적조사 기간 중 증상의 재발이나 만기사망률을 보인 환자는 없었다. 결론: 응급 수술의 경우 신속한 조치로 혈역학적 안정을 확보함과 동시에 심장에 비가역적인 손상이 오기 전에 적극적인 수술적 치료를 시행하여야 한다.

  • Background: Surgical repair of post-infarct ventricular septal defect (VSD) is considered one of the most challenging procedures having high surgical mortality. This study aimed to evaluate the outcomes of the surgical repair of post-infarct VSD. Methods: From May 1991 to July 2012, 34 patients (mean age, $67.1{\pm}7.9$ years) underwent surgical repair of post-infarct VSD. A retrospective review of clinical and surgical data was performed. Results: VSD repair involved the infarct exclusion technique using a patch in all patients. For coronary revascularization, 12 patients (35.3%) underwent concomitant coronary artery bypass graft, 3 patients (8.8%) underwent preoperative percutaneous coronary intervention, and 9 patients (26.5%) underwent both of these procedures. The early mortality rate was 20.6%. Six patients (17.6%) required reoperation due to residual shunt or newly developed VSD. During follow-up (median, 4.8 years; range, 0 to 18.4 years), late death occurred in nine patients. Overall, the 5-year and 10-year survival rates were $54.4%{\pm}8.8%$ and $44.3%{\pm}8.9%$, respectively. According to a Cox regression analysis, preoperative cardiogenic shock (p=0.069) and prolonged cardiopulmonary bypass time (p=0.008) were independent predictors of mortality. Conclusion: The early surgical outcome of post-infarct VSD was acceptable considering the high-risk nature of the disease. The long-term outcome, however, was still dismal, necessitating comprehensive optimal management through close follow-up.
