Intra-aortic balloon counterpulsation: rationale, application and results.

摘要: Intra-aortic balloon counterpulsation is an effective means of reducing myocardial ischemia and supporting the failing circulation. Its therapeutic benefits are direct result distolic augmentation systolic unloading, former increasing perfusion latter enhancing cardiac performance. Indirect effect include diminution by decrease in determinants oxygen demand improved ventricular function secondary to decreased ischemia. indicated clinical syndromes related intractable ischemia, including infarction shock severe left failure, refractory ischemic pains, arrhythmias unresponsive medical management. It also importance other situations associated with low output. This modality has recently been considered for early use extensive limit damage avert complications. Recent technical advances have facilitated ease safety application intra-aorta counterpulsation. Complication frequency but can be serious employment method predicated upon consideration both potential risks.
