• Spontaneous mitral chordal rupture is a complication in hypertrophic cardiomyopathy (HCM). • Mitral chordal rupture in HCM causes deterioration in heart failure. • Symptoms improved when left ventricular outflow tract (LVOT) obstruction disappeared. • Mitral valve has a role in LVOT obstruction and systolic anterior motion.
• 自发性二尖瓣腱索断裂是肥厚型心肌病（HCM）的一种并发症。
• 肥厚型心肌病中的二尖瓣腱索断裂会导致心力衰竭恶化。
• 当左心室流出道（LVOT）梗阻消失时，症状改善。
• 二尖瓣在左心室流出道梗阻和收缩期前向运动中起作用。
