This paper reviews recent biomechanical studies on heart valve flutter.The function of the heart valves is essential for maintaining effective blood circulation.Heart valve flutter is a Body Weight Scales kind of small vibration phenomenon like a flag fluttering in the wind, which is related to many factors such as a thrombus, valve calcification, regurgitation, and hemolysis and material fatigue.This vibration phenomenon is particularly prevalent in valve replacement patients.The biomechanical implications of flutter are profound and can lead to micro-trauma of valve tissue, accelerating its degeneration process and increasing the risk of thrombosis.
We conducted a systematic review along with a critical appraisal of published Lift Kit studies on heart valve flutter.In this review, we summarize and analyze the existing literature; discuss the detection methods of frequency and amplitude of heart valve flutter, and its potential effects on valve function, such as thrombosis and valve degeneration; and discuss some possible ways to avoid flutter.These findings are important for optimizing valve design, diagnosing diseases, and developing treatment strategies.
