ÖZET Giriş: Fontan ameliyatı tek ventrikül fizyolojisi için en sık yapılan ameliyatlardan biridir. Ameliyat sonrasında hastalar, uzamış plevral efüzyon ve başka komplikasyonlar açısından risk altındadır. Bu çalışmada; pulmoner arter basıncının, fenestrasyon yapılıp yapılmamasının, kullanılan ekstra kardiyak greftin çapının tromboproflaksi rejimlerinin sonrası gelişimine olan etkilerini araştırm...

OBJECTIVES Novel protocols were used to focus on dynamic cardiorespiratory function during submaximal exercise and on the recovery from 1-min pulses of exercise in children who had undergone Fontan corrections for single-ventricle lesions. BACKGROUND Particularly in children, maximal oxygen uptake (VO2max), which is commonly used to assess the functional capability of patients after the Fonta...

In recent decades, the Fontan procedure and its variations have resulted in markedly improved outcomes of patients with single-ventricle physiology. These improvements are expected to increase greatly the number of surviving patients, particularly those surviving long into adulthood. However, there is still a progressive risk of attrition and failure of the Fontan circulation over time, the und...

The effect of pulsatile pulmonary flow after the modified Fontan procedure was examined in a model that simulated the right heart. An inlet overflow tank (preload), axial pulsatile pump, Wind-Kessel model (afterload), and an outlet overflow tank were connected in series. The standard conditions were flow 2.00 l/min with 12 mm Hg preload pressure, 3.0 Wood units resistance, and an outlet overflo...

Protein losing enteropathy (PLE), defined as severe loss of serum protein into the intestine, occurs in 4–13% of patients after the Fontan procedure and carries a dismal prognosis with a five year survival between 46% and 59%. Chronically raised systemic venous pressure is thought to be responsible for the development of PLE in these patients, with perhaps superimposed immunological or inflamma...
