Implication

Supports acute hemodynamic gains with balloon dilatation in calcific AS; hypothesis-generating for percutaneous valve interventions in elderly patients.

Structured PICO

Does balloon dilatation improve valve hemodynamics and mobility in calcific aortic stenosis?

Population

12 cases of critically stenosed, calcified aortic valves (5 postmortem hearts, 5 intraoperative patients before aortic valve replacement, and 2 elderly female patients aged 93 and 85). Etiology: rheumatic (n=2), congenital bicuspid (n=1), senile calcific degenerative (n=9).

Intervention

Balloon dilatation with 12 to 18 mm valvuloplasty balloons

Outcome

Changes in valve rigidity, mobility, aortic gradients, cardiac index, and aortic valve areasurrogate

Balloon valvuloplasty is feasible and can acutely improve hemodynamics and valve mobility in calcific aortic stenosis, providing early evidence for percutaneous interventions in elderly patients.
