Dextrocardia with situs solitus and mitral valve insufficiency requiring surgical treatment is a rare presentation. Jehovah's Witnesses (JW), a specific religious group, deny any blood transfusion and for this reason the cardiac surgeon has to plan his operation well in advance, particularly in the case of adhesions from previous thoracic procedures.
A 50-year-old white female Jehovah's Witness with dextrocardia and situs solitus was referred for surgical treatment of massive mitral valve insufficiency of rheumatic etiology. Due to multiple adhesions from previous bilateral thoracotomies and the inverted position of the heart, cardiopulmonary bypass (CPB) was initiated with an aortic and a left common femoral vein cannulae. CPB was completed with an additional SVC cannula. The surgeon, having excellent exposure from the opposite side of the table, was able to perform a mitral valve replacement (MVR) with a 31 mm St. Jude Medical valve prosthesis, through a giant left atrium under moderate hypothermia and crystalloid cardioplegia. The operation was bloodless, with only two units of autotransfused blood being used with a postoperative hematocrit of 34%.
The patient had an uneventful recovery and has been in NYHA class I for 24 months now.
The case is presented for the safety of the approach, the excellent exposure from the left side in a dextrocardia case and the avoidance of blood transfusion in a Jehovah's patient.
右位心合并内脏正位且二尖瓣关闭不全需手术治疗的情况较为罕见。耶和华见证人(JW)是一个特定的宗教群体,拒绝任何输血,因此心脏外科医生必须提前精心规划手术,尤其是在既往有胸部手术粘连的情况下。
一名50岁的白人女性耶和华见证人,患有右位心合并内脏正位,因风湿性病因导致的重度二尖瓣关闭不全前来接受手术治疗。由于既往双侧开胸手术造成的多处粘连以及心脏位置倒置,采用主动脉插管和左股总静脉插管启动体外循环(CPB)。通过额外的上腔静脉插管完成体外循环。外科医生从手术台的对侧获得了极佳的视野,能够在中度低温和晶体心脏停搏液的情况下,经巨大左心房使用31毫米圣犹达医疗瓣膜假体进行二尖瓣置换术(MVR)。手术过程中无出血,仅使用了两单位自体输血,术后血细胞比容为34%。
患者恢复顺利,目前已处于纽约心脏协会(NYHA)心功能I级24个月。
展示该病例是为了说明手术方法的安全性、在右位心病例中从左侧获得的极佳视野以及在耶和华见证人教派患者中避免输血的情况。
