A bedside tool that accurately and rapidly identifies increased left ventricular (LV) filling pressure would be helpful. We evaluated acoustic electrocardiography for this purpose. METHODS We pooled 3 cohorts of patients for this analysis. Inclusion criteria required(More)
Patients with rheumatic heart disease and a history of mechanical aortic valve replacement will occasionally present with significant mitral stenosis for consideration of mitral balloon valvuloplasty. The conventional retrograde trans-aortic method for left heart catheterization cannot be done for patients with a mechanical aortic valve. We present a(More)
The signs and symptoms of systolic heart failure are frequently insensitive and nonspecific, making an accurate bedside diagnosis of left ventricular systolic dysfunction (LVSD) challenging. B-type natriuretic peptide (BNP) is often used, but is not diagnostically useful when in the indeterminate range. The authors investigated the diagnostic test(More)
