Abstrakt: There may be inter-/intra-surgeon variability in the repair of congenital heart defects. The objective was to analyze and visualize inter-/intra-surgeon variability in the level of patch suture lines and in the shape and size of patches developed through surgical simulation for partial anomalous pulmonary venous connection (PAPVC) repair using a patient-specific 3D-printed heart model. A patient with PAPVC and preoperative computed tomography data were selected, and a patient-specific heart model was obtained. Two different exposures on the model were tested. Two surgeons were enrolled. Both surgeons performed a single-patch repair on four heart models with one exposure and four models with the other. On the potential suture line, 20 points common in each model were allocated. The level of patch suture lines was represented as a deviation from the 20 points. The shape and size of the patches were analyzed and visualized using geometric morphometrics approaches, using the 20 points as landmarks to represent the patches. There was inter-surgeon variability in the level of patch suture lines, and the variability was higher in particular locations. There was inter-surgeon variability in the shape and size of patches, which was not affected by the exposures. The inter-surgeon variability in the shape of patches was higher in particular locations. There was intra-surgeon variability in the shape of patches. Inter-/intra-surgeon variability was analyzed and visualized by the surgical simulation using geometric morphometrics approaches. Further studies are needed to scrutinize whether the variability affects postoperative hemodynamics in actual surgery.
