ABSTRACT
Balloon aortic valvuloplasty (BAV) is a treatment for high risk patients with severe aortic valve stenosis (AS). Rapid pacing is needed to reduce cardiac output when dilating the balloon, but it may cause cardiac ischemia or lethal arrhythmia. In this case report, percutaneous cardiopulmonary support (PCPS) was used to prevent these complications with BAV. We achieved adequate blood pressure and cardiac output during BAV without using rapid pacing by drawing a certain amount of blood into the reservoir equipped with the PCPS circuit. When performing BAV, PCPS may be a useful option for the patients who have high risks of circulatory failure.
ABSTRACT
A 54-year-old man with ischemic mitral regurgitation underwent surgical ventricular restoration, mitral valve plasty and a coronary artery bypass. A chest X-ray 7 days later revealed pleural effusion on the right side. A chest tube was inserted and about 1,000 ml of fluid was drained. However, re-expansion pulmonary edema (RPE) occurred 2 h later. Positive pressure ventilation and intravenous infusion with a diuretic improved the RPE. He was resuscitated on the following day to receive percutaneous cardiopulmonary support (PCPS) for unstable hypoxemia and hypotension. Oxygenation improved, PCPS was withdrawn 2 days later, and the endotracheal tube was removed. Re-expansion pulmonard. He was resuscitated on the following day to receive percutaneous cardiopulmonary support (PCPS) for unstable hypoxemia and hypotension. Oxygenation improved, PCPS was withdrawn 2 days later, and the endotracheal tube was removed. Re-expansion pulmonary edema might cause fatal short-term cardio-respiratory failure. We considered that RPE requires appropriate early diagnosis, early treatment and aggressive therapy, including PCPS.
ABSTRACT
Blow-out type cardiac rupture after acute myocardial infarction (AMI) is usually a fatal complication. We report the case of a 64-year-old man, admitted to our hospital for AMI with cardiac shock. ECG and echocardiography showed a cardiac rupture after anterior AMI. We performed an emergency operation with a percutaneous cardiopulmonary support system (PCPS) and intra-aortic balloon pumping (IABP). The actively bleeding site, located at the anterior wall, was approximated using a large mattress suture with felt strips to close the rupture site, and the site was covered with fibrin glue. The patient was discharged on POD 48. We report a successful surgery for a case of blow-out type cardiac rupture after AMI.
ABSTRACT
BACKGROUND: We analyzed the clinical results and the factors for survival of patients who underwent extracorporeal life support system after adult cardiovascular surgery. MATERIAL AND METHOD: We retrospectively reviewed the medical record of 44 patients (1.6% of the total adult cardiovascular surgical cases) who underwent the use of a ventricular assisted device or extracorporeal membrane oxygenation from January 2002 to August 2008. There were 32 (72.7%) males and their mean age was 61.7+/-14.9 (range: 20~73) years old. The mean duration of extracorporeal life support system was 5.3+/-3.0 (range: 1~12) days. RESULT: Of these 44 patients, 24 (54.5%) patients were successfully weaned from the extracorporeal device. Eighteen (40.9%) survivors were able to be discharged from the hospital. Complications were noted in 38 patients (86.4%). An emergency operation, no usage of a concomitant intraaortic balloon pump and major complications during use of the extracorporeal life support system such as bleeding, flow instability and renal failure were identified as significant risk factors for poor survival on univariated analysis. Owing to educational support and a continuous renal replacement therapy system, the clinical outcomes of these patients have improved since 2006. On multivariated analysis, renal failure and bleeding during extracorporeal life support were significant risk factors for poor survival. CONCLUSION: Although using extracorporeal life support systems after adult cardiovascular surgery revealed acceptable clinical results, determining the optimal treatment strategy and further well designed larger studies are needed to improve the survival rate of patients who undergo extracorporeal life support after adult cardiovascular surgery

Percutaneous cardiopulmonary support (PCPS) provides hemodynamic and pulmonary support simultaneously and is increasingly used in medical practice. However, the presence of extracorporeal circulation and the use of heparin means it is not free of side effects, and use of PCPS for longer than 96 h is associated with poor prognosis. Therefore, along with the decision of when to apply or discontinue PCPS, an integrated team approach between the surgeon and the anesthesiologist to prevent and/ or manage PCPS-related complications is of paramount importance when the patient's physical status mandates prolonged use of PCPS. We hereby report 2 cases addressing successful management of postoperative cardiogenic shock, refractory to pharmacologic support, with early and prolonged application of PCPS in patients who underwent surgical anterior ventricular endocardial restoration and coronary artery bypass surgery.

A 61-year-old woman developed shock during transportation to our hospital in an ambulance under a diagnosis of acute myocardial infarction, Emergency coronary angiography showed left anterior interventricular descending branch #6 to be completely occluded. At the same time, ultrasonic cardiography showed pericardial effusion. Therefore we diagnosed left ventricular free wall rupture, and performed emergency surgery to repair the rupture site. After pericardiotomy massive hemorrhage occurred and we diagnosed blow-out type left ventricular free wall rupture. We immediately established extracorporeal circulation via the femoral artery and vein, and cross clamped the ascending aorta, then achieved cardiac arrest. Because the area of myocardial infarction was extensive, we applied the David-Komeda method to avoid bleeding due to left ventricular systolic pressure, left ventricular aneurysm or ventricular septal rupture. The postoperative course was good; the patient was weaned from PCPS on the 3rd day postoperatively, IABP on the 5th day postoperatively and from the respirator on the 8th day postoperatively. She was discharged on postoperative day 40. Currently she has no cardiac complains, no left ventricular aneurysm and no neurological problems. Left ventricular free wall rupture can remain a fatal complication after acute myocardial infarction. We consider the David-Komeda method useful for repairing left ventricular free wall rupture (blow-out type) after acute myocardial infarction as well as ventricular septal rupture without a risk of left ventricular aneurysm, bleeding or ventricular septal wall rupture.
ABSTRACT
In general strategy for postcardiotomy heart failure includes inotropic support followed by the use of an intra-aortic balloon pump and percutaneous cardiopulmonary bypass support (POPS). The insertion of a ventricular assist system (VAS) may become necessary when these procedures fail to restore hemodynamic stability. The ABIOMED BVS 5000 left ventricular assist support system (LVAS) has been approved for clinical use in Japan since 1998. Here we describe our experience with the recovery of a 52-year-old man from postcardiotomy heart failure after using an ABIOMED BVS 5000 LVAS. The patient was admitted to our institution with dyspnea. Heart failure with severe left ventricular dysfunction was diagnosed, and recent myocardial infarction was suspected from his history and electrocardiogram. Two days after admission, ventricular fibrillation occured and the arrythmia was hard to control. PCPS was connected and emergency coronary angiography showed triple vessel disease. We performed emergency coronary artery bypass grafting with the heart beating under PCPS and immediately implanted an ABIOMED BVS 5000 device to achieve myocardial recovery after stopping PCPS. He was weaned from the LVAS at 6 days after surgery. His postoperative course was relatively uneventful and he was discharged after recovery.
ABSTRACT
The survival rate of patients with cardiac rupture due to a blunt trauma is low, therefore it is necessary to have a well-defined diagnostic and treatment plan in order to improve the survival rate. In 8 such patients transthoracic echocardiograms at the time of arrival at our hospital showed pericardial effusion with cardiac tamponade in all patients. The mean time between suffering the injury and arriving at the hospital was 186±185min, and the mean time between arrival and being brought to the operating room was 82±49min. Preoperative pericardial drainage was performed in 2 patients, and percutaneous cardiopulmonary support system was used in 2 patients. The rupture site was in the right atrium in 3 patients, the right atrium-inferior vena cava in 1 patient, the right ventricle in 2 patients, the left atrium in 1 patient, and the left ventricle in 1 patient. Extracorporeal circulation was used in 4 patients, and the injured site was repaired. We were thus able to save the lives of 6 of the 8 patients (survival rate 75%). Transthoracic echocardiography was easy to perform and effective for making an accurate diagnosis. Many such patients tend to have multiple traumas, but, if the patient is in a state of shock due to cardiac tamponade, the patient should be moved immediately to the operating room. It is important to provide circulatory maintenance until surgery, and pericardial drainage and PCPS are also effective additional treatment modalities.
ABSTRACT
Circulatory support devices have become an important component for transplantation programs as they successfully bridge unsalvageable patients who would otherwise die. Between October 1997 and April 2001, 6 patients in profound heart failure were treated with a percutaneous cardiopulmonary support system (PCPS), or with ventricular assist device (VAD), or with both PCPS and VAD. Two patients were treated only with a PCPS, and one weaned case survived. Another 2 patients, who had dilated cardiomyopathy, was treated with VAD. They improved hemodynamically, and their general conditions made them fit to be candidates for heart transplantation. Two other patients who had PCPS insertion before VAD died due to multiple organ failure. Before the application of VAD, the levels of total bilirubin were 14.9 and 20.9mg/dl respectively. In acute worsening of hemodynamics, PCPS is useful to maintain total circulation by quick application. However, long-term support with VAD should be considered to resuscitate impaired end-organ function by carefully selecting the timing of a VAD implantation.
ABSTRACT
A 69-year-old man in whom two stents had been implanted on segments 6 and 7 was admitted to our hospital with acute myocardial infarction (AMI). Coronary angiography suggested a total occlusion of the left anterior descending (LAD) between two stents. Percutaneous transluminal coronary angioplasty (PTCA) was performed, but it made an acute coronary occlusion due to a dissection of left main trunk (LMT). As cardiogenic shock occurred, he was put on percutaneous cardioplumonary support (PCPS), and a perfusion catheter was introduced to the LAD and a guide wire to the circumflex (Cx). Emergency coronary artery bypass grafting (CABG) was performed on cardioplumonary bypass (CPB). First, an SVG was grafted to the LAD on ventricular fibrillation, and the other SVG was grafted to segment 13 on cardiac arrest after the perfusion catheter and guide wire was removed. This method allowed this operation to be performed with suitable myocardial protection.
ABSTRACT
An emergency percutaneous cardiopulmonary support system (PCPS) was employed 11 arrest victims (5 males, 6 females; mean age 59.3 years) refractory to conventional resuscitation measures. Cardiac operation was subsequently performed in two patients and coronary angioplasty in two. The 7 other patients continued on cardiopulmonary support by PCPS after successful resuscitation. Duration of support was 10.5±9.1 (mean±S. D.) hours, the flow rate was 2.5±0.7<i>l</i>/min, and PCPS was applied 5-70min (mean, 24.9min) following the onset of cardiac arrest. The entire intraluminal surface of PCPS device had been heparin coated, activated coagulation time was maintained about 150 seconds, with or without minimal systemically administered heparin. Seven of 11 patients (63.6%) were successfully weaned from the PCPS. The early survival (<30 days) was 6 patients (54.5%), and late survival was 4 patients (36.4%). We conclude that PCPS can improve survival in patient unresponsive to conventional resuscitation when instituted soon after cardiac arrest.
ABSTRACT
A 22-year-old man was referred to our medical center with an impending rupture of an aneurysm of the descending thoracic aorta. Blood pressure was 180/110mmHg in the right arm but 110/60mmHg in the right foot. The diagnosis was confirmed by chest Xray, enchanced computed tomography and aortogram. Five days later, the chest Xray showed massive effusion in the left pleural cavity. Surgery was immediately performed via a left thoracotomy. Five hundred ml of bloody fluid was found in the pleural cavity but the site of bleeding could not be identified. The aneurysm was 7×10cm in size. Under percutaneous cardio pulmonary support, the aneurysm was replaced by a 22mm Gel-Seal Dacron vascular graft. The intima and the media of the aneurysm were lacerated longitudinally at the region receiving jet flow from isthmus, There was blood coagula between the media and adventitia. During replacement, activated clotting time was maintained at 200∼300sec. As a result, bleeding was limited to 200ml. The postoperative course was uneventful with little difference in pressure between the right arm and right foot.
