Abstract:
To develop a predictive model for optimal anastomosis sizing in TAPVC surgery, focusing on the role of pulmonary venous confluence (PVC) size. A patient-specific fluid-structure interaction (FSI) model simulated blood flow through various anastomosis sizes. Key variables included body weight, anastomosis length, and PVC size. The model's predictions were validated against postoperative echocardiographic measurements from nine TAPVC cases. A strong positive correlation was found between flow velocity and the ratio of body weight to anastomosis length and PVC circumference. Including PVC size significantly improved predictive accuracy. No significant difference was observed between predicted and measured velocities. PVC size is a critical factor for planning TAPVC surgery. Incorporating it into computational models enhances the prediction of flow dynamics and supports personalized surgical decision-making.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
