Short-term follow-up after percutaneous aortic balloon valvuloplasty shows a high incidence of restenosis. Yet a high percentage of patients with restenosis continue to show symptomatic improvement. Those with decreased left ventricular function originally tend to have a recurrence of symptoms. In this study Doppler-derived diastolic filling values at follow-up were most highly associated with symptom status, suggesting that change in diastolic filling after percutaneous aortic balloon valvuloplasty is one of the factors related to symptoms.
