Article Synopsis
- Left ventricular outflow tract obstruction (LVOTO) can occur in older patients without hypertrophic cardiomyopathy (non-HCM), even if pressure gradients are below 30 mmHg at rest.
- This study included 33 non-HCM patients and examined their LVOT using Doppler measurements before and after the Valsalva maneuver and an upright sitting maneuver.
- Results showed that 61% of patients demonstrated latent LVOTO after these maneuvers, with the sitting maneuver being more effective, particularly among those with a smaller angle between the left ventricular septum and aorta.

Article Synopsis
- * Results showed that while the accuracy of detecting regional wall-motion abnormalities (RWMAs) improved slightly with the slow-motion technique (87.5%) compared to conventional ESE (81.0%), this difference was not statistically significant.
- * The new method demonstrated enhanced image readability and better interreader agreement among cardiologists, suggesting it could be a beneficial tool to assist physicians in evaluations, despite the accuracy not being significantly improved.
