However, when the resting gradient is near the lower boundary of the moderate range, establishing whether exercise intolerance is attributable to PVS can be challenging. We describe the case of a 52\u2010year\u2010old woman with longstanding PVS who developed progressive exercise intolerance. Resting echocardiography revealed a peak gradient of 38\u2009mmHg, which remained stable during follow\u2010up. Exercise stress echocardiography (ESE) demonstrated a blunted stroke volume response, whereas cardiopulmonary exercise testing (CPET) showed reduced peak VO\n                    <jats:sub>2<\/jats:sub>\n                    . Based on these objective findings, BPV was performed for symptomatic moderate PVS.
