Abstract

Background: This study aims to evaluate early postoperative results of orthotopic heart transplantation using bicaval and biatrial technique. Methods: Between September 1989 and December 2008, 61 patients who underwent orthotopic heart transplantation in our clinic were included. Patients were divided into two groups according to the surgical technique used. Standard biatrial anostomosis technique was performed on 28 patients (mean age 31.8±12.5 years; range 16 to 58 years), while bicaval anostomosis technique was performed on 33 patients (mean age 29.8±9.9 years; range 17 to 48 years). There was no significant difference between two groups with respect to the preoperative patient characteristics and demographic data. However, the incidence of pulmonary dysfunction (p<0.05) and renal dysfunction (p<0.05) were higher in biatrial group. Mean cross clamping and cardiopulmonary bypass time were 73.9±13.6 and 114.4±20.8 minutes in biatrial group and 77.4±15.1 and 127.7 ±19.5 minutes in bicaval group. Results: It was observed that the necessity of temporary pacemaker (p<0.05), increasing incidence of branch block (p<0.01) and atrioventricular block (p<0.05) were significantly higher in biatrial group. One patient required permanent pacemaker and one other patient required intracardiac defibrillator (ICD) implantation. Postoperative echocardiographic examination revealed that the incidence of tricuspid (p<0.01) and mitral insufficiency (p<0.01) were lower in bicaval group compared to biatrial group. Right ventricular hemodynamic function was maintained better in patients who underwent orthotopic transplantation using bicaval technique. Arrhythmia (ventricular arrhytmia and early atrial pulse) and atrioventricular valve insufficiency were less observed in this patient group. Also rhythm returned to normal earlier in bicaval group than biatrial group. Conclusion: With regard to the results which influence early morbidity, bicaval technique was superior to the biatrial technique. Due to its observed benefits, bicaval anastomosis technique has become the routine for orthotopic heart transplantation in our clinic.

Özet

Amaç: Bu çalışmada bikaval ve biatriyal teknik kullanılarak ortotopik kalp nakli yapılan hastaların erken ameliyat sonrası sonuçları incelendi. Çalışma planı: Kliniğimizde Eylül 1989 ile Aralık 2008 tarihleri arasında ortotopik kalp nakli yapılan 61 hasta çalışmaya dahil edildi. Hastalar kullanılan cerrahi tekniğe göre iki gruba ayrıldı. Hastaların 28’ine (ort. yaş 31.8±12.5 yıl; dağılım, 16-58 yıl) standart biatriyal anastomoz tekniği, 33’üne (ort. yaş 29.8±9.9 yıl; dağılım, 17-48 yıl) bikaval anastomoz tekniği kullanılarak nakil yapıldı. Her iki grup arasında ameliyat öncesi hasta özellikleri ve demografik veriler açısından anlamlı fark yoktu. Bununla birlikte, akciğer (p<0.05) ve renal (p<0.05) fonksiyon bozukluğu insidansı biatriyal grupta daha yüksek idi. Ortalama kros klemp ve kardiyopulmoner baypas süreleri biatriyal grupta 73.9±13.6 ve 114.4±20.8 dakika, bikaval grupta 77.4±15.1 ve 127.7±19.5 dakika idi. Bulgular: Biatriyal grupta geçici pacemaker gereksinimi (p<0.05), dal blok’u (p<0.01) ve atriyoventriküler blok (p<0.05) oluşumunun anlamlı olarak fazla olduğu görüldü. Ayrıca biatriyal grupta bir hastaya kalıcı kalp pili ve bir hastaya da intrakardiyak defibrilatör (ICD) uygulama gereksinimi oldu. Ameliyat sonrası ekokardiyografik incelemede bikaval teknikle ameliyat edilen hastalarda, triküspit (p<0.01) ve mitral yetmezliği (p<0.01) biatriyal grupla karşılaştırıldığında, anlamlı olarak daha az görüldü. Bikaval teknik kullanılarak ortotopik nakil yapılan hastalarda, sağ ventriküler hemodinamik fonksiyon daha iyi korundu. Bu hasta grubunda aritmi (ventriküler ve erken atriyal vurular) ve atriyoventriküler kapak yetmezliği daha az gözlemlendi. Ayrıca ritim bikaval grupta, biatriyal gruptan daha erken sürede normale döndü. Sonuç: Bikaval teknik, erken dönem morbiditeyi etkileyen sonuçlar bakımından biatriyal teknikten üstün bulundu. Ortotopik kalp nakli için bikaval anastomoz tekniği gözlemlediğimiz faydalardan dolayı kliniğimizde tercih edilen bir yöntem haline geldi.
