No postoperative arrhythmia was observed in patients with a right atrial pressure of 10 mmHg and a preoperative right atrial pressure of >5 mmHg were the risk factors for postoperative arrhythmia in patients undergoing Fontan procedure, the right or left ventricular dominance was not a risk factor.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Objective: Advanced age, dilated right atrium, increased preoperative pulmonary artery pressure, increased right atrial pressure, technique of operation, and poor ventricular function were reported to be risk factors for postoperative arrhythmia.
📊
Key Findings & Data:Results: Arrhythmia was observed in 21 (52.5%) patients in the postoperative period.
💡
Conclusion & Impact:No postoperative arrhythmia was observed in patients with a right atrial pressure of 10 mmHg and a preoperative right atrial pressure of >5 mmHg were the risk factors for postoperative arrhythmia in patients undergoing Fontan procedure, the right or left ventricular dominance was not a risk factor.

Abstract

Objective: Advanced age, dilated right atrium, increased preoperative pulmonary artery pressure, increased right atrial pressure, technique of operation, and poor ventricular function were reported to be risk factors for postoperative arrhythmia. Aim of this study is to determine the risk factor for postoperative arrhythmia after Fontan operation with regard to ventricle dominancy and hemodynamic parameters. Methods: In this retrospective study, the data of the patients including age, weight, dominant ventricle, type of cardiac anomaly, previous operations, duration of cardiopulmonary bypass (CPB), duration of aortic clamping, cardiac rhythm, pulmonary artery pressure, the Nakata Index, systemic atrioventricular (AV) valve insufficiency were obtained from the hospital records, the echocardiographic files, and cardiac catheterization records. Patients were assigned to dominant left ventricle or dominant right ventricle groups. Statistical analysis was performed using the Mann-Whitney U test. Results: Arrhythmia was observed in 21 (52.5%) patients in the postoperative period. No postoperative arrhythmia was observed in patients with a right atrial pressure of 10 mmHg and a preoperative right atrial pressure of >5 mmHg were the risk factors for postoperative arrhythmia in patients undergoing Fontan procedure, the right or left ventricular dominance was not a risk factor.

Özet

Amaç: Literatürde yapılan çalışmalarda ileri yaş, sağ atriyum boyutunun büyüklüğü, ortalama pulmoner arter basıncı, sağ atriyum basıncı, sistemik ventrikülün düşük ejeksiyon fraksiyonu, ameliyat tekniği postoperatif aritmi için risk faktörü olarak saptanmıştır. Bu çalışmada sistemik dolaşımı sağlayan ‘dominant ventrikül’ ün sağ ventrikül ya da sol ventrikül olmasının ve hemodinamik parametrelerin postoperatif aritmi açısından risk faktörü olup olmadığı araştırılmıştır. Yöntemler: Fontan ameliyatı yapılmış 1997 ve 2008 yılları arasındaki 40 hastanın verileri retrospektif olarak değerlendirildi. Hastaların ekokardiyografi notları, kardiyak kateterizasyon notları, ameliyat notları, yaş, kilo, dominant ventrikül tipi, kardiyak anomali tipi, geçirilmiş operasyonlar, kardiyopulmoner baypas süresi, aort klemp süresi, kardiyak ritim, pulmoner arter basıncı, Nakata indeksi, sistemik atriyoventriküler kapak yetmezliği kaydedilerek çalışmamıza dahil edilmiştir. Hastalar dominant sol ventrikül ve dominant sağ ventrikül olarak ayrıştırıldılar. İstatistiksel analiz Mann-Whitney U test kullanılarak gerçekleştirildi. Bulgular: Postoperatif dönemde toplam 21 hastada (%52.5) aritmi görülmüştür. Preoperatif sağ atriyum basınçlarına bakıldığında sağ atriyum basıncı 5 mmHg’dan düşük hastalarda postoperatif aritmi gözlenmezken sağ atriyum basıncı 5 mmHg ve daha yüksek olan hastalarda postoperatif aritmiler görülmüştür (p
