Representative cases. A: Patient A, without diabetes, had low HbA1c levels during follow-up (mean HbA1c, 5.7%) and showed a slow progression of AS (△Vpeak/year, 0.2 m/sec/year; △meanPG, 2.2 mmHg/year; △AVA, -0.09 cm2/year). B: Patient B was diagnosed as having diabetes, and maintained a tight glycemic control (mean HbA1c, 6.1%). During follow-up, the progression of AS was modest (△Vpeak/year, 0.3 m/sec/year; △meanPG, 5.1 mmHg/year; △AVA, -0.11 cm2/year). C: Patient C, in whom the glycemic control was poor (mean HbA1c, 8.9%), showed an accelerated AS progression during follow-up (△Vpeak/year, 0.7 m/sec/year; △meanPG, 10.5 mmHg/year; △AVA, -0.36 cm.2/year)
