Two men with failed mitral valves died after the initial surgery.(兩名伴損毀二尖瓣的男性術后死亡。)

People with panic disorder are more likely to have mitral valve prolapse, hypertension, peptic ulcer, diabetes, angina or thyroid disease.(有驚恐障礙的人更容易有二尖瓣脫垂，高血壓，消化系統潰瘍，糖尿病，心絞痛或甲狀腺疾病。)

Objective To review the experience of mitral valve repair (MVP) for mitral regurgitation in 17 patients.(目的總結二尖瓣成形術治療二尖瓣關閉不全17例的經驗。)

Aim: To assess the effect of the totally flexible prosthetic ring in mitral and tricuspid annuloplasty.(目的：評價全軟成形環在二尖瓣關閉不全瓣環成形術中的作用。)
