三尖瓣修复手术策略课件

三尖瓣修复手术策略病理三尖瓣的临床重要性常被低估，且临床相关文献也很少。三尖瓣疾病常由其他瓣膜疾病所致。但是:二尖瓣或主动脉瓣修复术并不能缓解三尖瓣关闭不全。二尖瓣狭窄患者同时进行或未进行三尖瓣手术的结果继发性三尖瓣关闭不全病理瓣环扩大(LsVD,肺动脉高压)创伤后三尖瓣关闭不全类癌综合症中的三尖瓣狭窄感染性心内膜炎先天性解剖学异常修复手术适应症我知道,我不知道!文献报导中，很多作者讨论了右心室功能障碍在三尖瓣返流发生中的作用:谁是因，谁是果?同时纠正会影响远期预后吗?二尖瓣狭窄患者同时进行或未进行三尖瓣手术的结果继发性三尖瓣关闭不全二尖瓣狭窄患者同时进行或未进行三尖瓣手术的结果继发性三尖瓣关闭不全修复手术适应症尽管许多问题目前没有明确的答案，但一致认为最好同时进行三尖瓣修复手术。我们认为，中重度三尖瓣返流和瓣环直径大于30 mm或直径指数大于 20 mm/m 是修复手术适应症。二尖瓣狭窄患者同时进行或未进行三尖瓣手术的结果继发性三尖瓣关闭不全二尖瓣狭窄患者同时进行或未进行三尖瓣手术的结果继发性三尖瓣关闭不全Cardiovascular Surgery 2001;Vol 9,Nr

Cardiovascular SurgeryUniversity Hospital Giessen and MarburgCampus MarburgPathologiesThe tricuspid valve is underestimated in its clinical importance and also under-represented in literature.Tricuspid valve disease is mainly seen as a consequence of other valvular dysfunctions.But:The correction of the mitral-or aortic-valve does not necessarily lead to an improvement of the tricuspid insufficiency.Outcome of patients after MVS with or without concommittant TV-surgeryOutcome of secondary TVIOutcome of secondary TVIOutcome of patients after MVR with and without

of secondary TVIOutcome of patients after MVS with or without concommittant TV-surgeryOutcome of secondary TVIIndications for repairWhereas many questions are not definitively answered,there is general agreement,that concommittant surgery of the tricuspid valve should be preferred.Accordingly we consider moderate to severe tricuspid valve regurgitation and an annular diameter of 30 mm respectively an indexed diameter of 20 mm/m an indication for repair.Outcome of patients after MVS with or without concommittant TV-surgeryOutcome of secondary TVIOutcome of patients after MVS with or

agreement among most authors,that repair is the first choice at least in primary interventions.While recent publications propably prefer ring annuloplasties,the majority of studies does not show a superiority compared to suture annuloplasties(i.e.DeVega plasty).Type of repairAccording to literature and based on own experiences,we prefer a simple suture annuloplasty in terms of a modified DeVega plasty in cases of moderate regurgitation and moderately dilated annuli.Deep enough stitches,alternating between the two suture lines,are mandatory for a satisfactory longterm result.Operative

necessary.PathologiesPosttraumatic tricuspid insufficiencyThe clover technique“Alfieri et al.J Thorac CardiovascSurg 2003;126:75-9PathologiesAnnulodilatation(LsVD,PHt)Posttraumatic TITricuspid stenosis in Carcinoid syndromeEndocarditisCongenital malformationsPathology and type of repairIn patients with Carcinoid syndrome,involvement of the right sided heart valves,especially the tricuspid valve,is a common complication.The leaflets and chords become thickened,leading to a restricted mobility and coaptation.The therapy of choice is the replacement of the valve.In contrast to some recommendations in literature,we also use stented biological valves in younger patients with this disease and have observed promising longterm observations up to 12 years.Echo-findings in Carcinoid

more frequent in recent years,mainly caused by the infection of foreign bodies(pacemaker leads,port catheters).Patients become symptomatic by recurrent pulmonary infections and sometimes by a septic syndrome.PathologyEcho-findings in tricuspid valve endocarditisEcho-findings in tricuspid valve endocarditisPathologyIndication and type of repairSurgery should be performed early before pulmonary or even general complications have occured.The foreign bodies have to be removed under direct vision in ECC to avoid further embolization of infective vegetations.A repair of the tricuspid valve should be aimed at in all cases.Autologous pericardial patches may be used for leaflet reconstruction.Foreign material should be avoided if possible.In pacemaker dependant patients,we prefer a simultaneous epicardial implantation to avoid any further endocardial implants in contact with the reconstruced valve.PathologiesTricuspid valve endocarditisGottardi R.et al.,Ann Thorac Surg
