Deep learning is a popular AI technique used in various fields, including healthcare, due to its ability to process complex data and recognize patterns that are difficult for humans to identify, potentially aiding in disease diagnosis. The methods used in this study were Convolutional Neural Network methods such as MobileNetV2, ResNet50, ResNet101, DenseNet101, and DenseNet201, as well as Explainable Artificial Intelligence method Grad-Cam. The dataset used was fetal echo image data from Dr. Mohammad Hoesin Central General Hospital. The study focused on finding the best Convolutional Neural Network model for classifying fetal heart disease abnormalities. After classification using the Convolutional Neural Network architecture, image visualization was applied using Grad-Cam. The main parameters used in this study were accuracy, sensitivity, and specificity. The results of the classification process showed that the DenseNet101 architecture had the best evaluation values, with an accuracy of 88.5%, sensitivity of 60%, and specificity of 93.3%. For the Grad-Cam implementation, the model was effective in visualizing abnormal images, but not as effective in normal images as the heatmap was still detected.} }
