Influence of different implantation techniques on AV valve competence after orthotopic heart transplantation

Abstract: This study showed excellent long-term survival rates for both groups. The significant reduction of left atrial size and atrio-ventricular valve regurgitation in the TOHT group might have important impact on the long-term preservation of cardiac function. Total orthotopic heart transplantation with bicaval and pulmonary venous anastomosis should be preferred for heart transplantation.

“…Shortly after the technique of bicaval anastomosis was introduced by Yacoub and colleagues in 1989 (5), there were multiple single center reports of improved TVR over time when compared to the standard bi-atrial technique (6,7). The enlarged right atrial size of the combined atria in the bi-atrial technique was thought to exacerbate the development of TVR by increasing both wall tension and tricuspid annular size during systole (8). In addition to anatomic distortion, the bi-atrial anastomosis was also thought to lead to asynchronous atrial contractions leading to further dilation over time.…”

“…Рассматривают следующие причины развития подобной патологии: технику хирургического анас-томоза при имплантации донорского сердца [16][17][18], повреждение хордального аппарата трикуспидаль-ного клапана и его створок при эндомиокардиальной биопсии [19][20][21], эпизоды острого клеточного оттор-жения трансплантата [22], болезнь коронарных арте-рий пересаженного сердца [23,24], наличие легочной гипертензии у реципиента в предтрансплантационном периоде [25,26]. Ввиду разнообразия факторов, спо-собных приводить к недостаточности трикуспидаль-ного клапана, потенциально принято условно разде-лять их на факторы, приводящие к функциональной и органической недостаточности (рис.)…”

“…Koch et al при сравнении двух методов имп-лантации сердца пришли к выводу, что увеличение размеров правого предсердия, возникающее после выполнения биатриальной методики, может являться причиной развития недостаточности трикуспидаль-ного клапана вследствие увеличения напряжения стенки правого предсердия и размеров трикуспи-дального фиброзного кольца, происходящего в сис-толу [18].…”

“…Reasons for converting to nonstandardt echniques included concern over tricuspid valve dysfunction, right ventricular performance, and arrhythmias or heart block. Av ariety of retrospective studiesh ave compared the end-points of atrioventricular valvular regurgitation, postoperative arrhythmias,a nd need for pacemakers in patients undergoing each of these operative techniques (24,25,26). In these reports, the incidence of tricuspid valvular regurgitation is consistently less in the bicaval or total techniques when compared to the biatrial technique.…”
