| Popis: | Low cardiac output is a continuing cause of mortality after intracardiac operations in patients coming to surgery with advanced myocardial dysfunction. Intra-aortic balloon counterpulsation (IABC) may be effective in improving the hemodynamic state of some of these patients. However, there are patients who clearly require even greater circulatory support if they are to survive. It has been a common experience that the hemodynamic state of patients who are unable to come off cardiopulmonary bypass (CPBP) may be stabilized as long as volumes substantially less than total systemic blood flow (approximately 25% to 50%) are mechanically shunted around the left ventricle. Although there is agreement that partial left ventricular bypass (PLVB) could be of value in managing post-cardiotomy low output, a major impediment has been the need to reenter the thoracic cage for subsequent cannula removal. A technique of cardiac support has been developed using cannulae sutured to the left atrium and ascending aorta which are connected to a simple pump circuit. Thoracic reentry is not required when cardiac support is discontinued. |
