Key result
Percutaneous aortic balloon dilatation is associated with a ~38% lower mean systolic gradient in severe AS.
Why the study?
Percutaneous aortic balloon dilatation is considered as an alternative treatment for elderly patients with severe calcified aortic stenosis who are poor surgical candidates, but its immediate haemodynamic effects and short-term outcomes require evaluation.
Does percutaneous aortic balloon dilatation improve haemodynamics and clinical symptoms in elderly patients with severe calcific aortic stenosis?
Observational (n=8)
No
Does percutaneous aortic balloon dilatation improve haemodynamics and clinical symptoms in elderly patients with severe calcific aortic stenosis?
Percutaneous aortic balloon dilatation provides palliative haemodynamic and clinical improvement in elderly patients with severe calcific aortic stenosis who are poor surgical candidates.
No takes yet. Share an insight, caveat, or question.
May palliate hemodynamics in inoperable elderly severe AS; hypothesis-generating and requires prospective validation.
Mario et al. (1987) conducted an observational in Severe calcified stenosis of the aortic valve (n=8). Percutaneous aortic balloon dilatation was evaluated on Haemodynamic changes (left ventricular pressures, mean systolic gradient, systolic aortic flow, and aortic valve area). Percutaneous aortic balloon dilatation in elderly patients with severe calcific aortic stenosis improved mean systolic gradient (from 66 to 41 mm Hg) and aortic valve area (from 0.47 to 0.74 cm2).
