Excerpt
The detailed baseline and acute changes in left ventricular performance characteristics during repeat balloon aortic valvuloplasty have not been evaluated relative to the initial procedure. In previous studies, acute left ventricular function hemodynamics have not been measured with even simple variables such as ejection fraction (1-3).
Some patients, due to advanced age or comorbid disease, present an extraordinary risk for cardiac surgery. Despite symptomatic restenosis of a previously dilated aortic valve, repeat balloon aortic valvuloplasty therefore is being offered as palliative therapy (1-3). Although the initial procedure generally provides early symptomatic improvement (1-5), the clinical outcome of patients requiring repeat
