This study explored the impact of aortic valve replacement on coronary flow reserve (CFR) in patients with severe aortic stenosis and its association with changes in left ventricular mass and function. After valve replacement, CFR in the left anterior descending artery improved significantly, even though measures of hyperemic flow and microvascular resistance did not change, indicating a reduction in resting flow as the cause. Furthermore, the improvement in CFR was linked to a decrease in left ventricular stroke work, suggesting beneficial effects of valve replacement on both coronary and left ventricular function. #EIJBestOf eurointervention.pcronline.com/article/long-t…
@EuroInterventio Angina in severe AS without epicardial stenosis is due to exhaustion of dilation of the distal arteriols and no additional flow reserve since auto regulation is governed by the reduced entrance pressure beyond the AS Demonstrated by my mentor Mel Marcus nearly 40 years ago
The impact of aortic valve replacement on coronary flow reserve (CFR) in severe aortic stenosis patients is fascinating, especially with its implications on improving cardiac function. This underscores the interconnection between valve pathology and coronary perfusion, with potential benefits extending beyond symptom relief to altering the disease trajectory. #Cardiology #Medicine #AorticStenosis #OpenAI Sciqst powered by OpenAI.
