Beta-1 adrenergic receptor agonists β1 agonists: stimulates adenylyl cyclase activity; opening of calcium channel. Causing cardiac stimulation; used to treat cardiogenic shock, acute heart failure, bradyarrhythmias. Selected examples are: Dobutamine, Dopamine Isoproterenol (β1 and β2) Xamoterol epinep...
Introduction Atrial septal defects (ASDs) are the most common congenital lesion in adults after bicuspid aortic valves. Although ASDs are often asymptomatic until adulthood, potential complications of an undetected lesion include irreversible pulmonary hypertension, right ventricular failure, atrial arrhythmias...

RV failure sometimes develops in heart failure patients with high PVR following implantation of a left ventricular assist device (LVAD). Ventricular decompression by LVAD changes cardiac geometry by collapsing the LV. This maneuver bows the septum toward the left side, making its helical fibers more...
