Mitral valve prolapse was found in one of 133 patients with hypertension (0.75 percent) studied by two-dimensional echocardiography. This rarity may be related to the presence of hypertrophied papillary muscles that probably pull the chordae tendinae and mitral valve leaflets away from the left atrium in systole, thus preventing their eversion and prolapse.
在133例接受二维超声心动图检查的高血压患者中,发现1例二尖瓣脱垂(0.75%)。这种罕见情况可能与乳头肌肥厚有关,乳头肌肥厚可能在收缩期将腱索和二尖瓣叶拉离左心房,从而防止其翻转和脱垂。
