Severe tricuspid regurgitation with permanent pacemaker wire passing through the orifice of bioprosthetic tricuspid valve is extremely rare. We present a case of such kind of patient and redid bioprosthetic tricuspid valve replacement. A hawk mouth forceps for bone surgery was used to cut off the mental ring of ruined bioprosthetic tricuspid valve and the ruined valve was removed. A new bioprosthetic tricuspid valve was implanted and the wire of permanent pacemaker was left outside the ring of bioprosthetic tricuspid valve. This method may be helpful for such kind of patient.

目的了解安徽省妇幼保健服务3类目标人群对新生儿和婴儿基本知识的知晓状况。方法 "安徽省妇幼保健相关人群母婴健康素养调查"采用分层整群抽样方法,在全省抽取10个县(区)妇幼保健机构、15个社区卫生服务中心和15个乡镇卫生院,对婚检人群、孕妇夫妇、儿童家长进行问卷调查。本文从该项目数据库中提取新生儿及婴儿基本知识等相关数据进行统计分析。结果在5076名调查对象中,婚检对象2032人(40.0%),孕妇夫妇1487人(29.3%),儿童家长1557人(30.7%)。新生儿和婴儿基本知识知晓率为2.9%,其中婚检人群1.7%、孕妇夫妇3.0%、儿童家长4.5%。单因素Logistic回归分析显示,新生儿和婴儿基本知识知晓率与人群分类、城乡、性别、年龄、文化程度和职业等因素相关(P<0.05)。多因素Logistic回归分析显示,新生儿和婴儿基本知识知晓率与人群分类、性别、年龄、文化程度和职业等因素相关(P<0.05)。结论安徽省妇幼保健目标人群对新生儿和婴儿基本知识的知晓率仅为2.9%,影响知晓率的相关因素有性别、年龄、文化程度和职业等。亟待采取措施加强对新生儿和婴儿基本知识的宣传教育。
