Acute right ventricular infarction: insights for the interventional era.

摘要: Acute right ventricular infarction is associated with higher in-hospital morbidity and mortality related to life-threatening hemodynamic compromise arrhythmias during acute occlusion abruptly reperfusion, complications which have implications for interventional management. coronary artery proximal the (RV) branches results in depressed RV systolic function, leading diminished transpulmonary delivery of left preload resulting low-output hypotension. Under these conditions, pressure generation output are dependent on ventricular-septal contraction via paradoxical septal motion. With culprit lesions distal atrial (RA) branches, augmented RA contractility enhances performance cardiac output, whereas occlusions induce ischemia, exacerbates compromise. Hypotension may respond volume resuscitation restoration a physiologic rhythm. Refractory cases usually parenteral inotropes, though some mechanical support required. The ventricle relatively resistant recovers even after prolonged occlusion. percutaneous reperfusion recovery improves clinical course survival patients infarction.
