Optimal Prenatal Diagnosis Model for Fetal Heart VSD Detection Using Hybrid Deep Learning
Ventricular Septal Defect (VSD) accounts for 26% of CHDs, with an incidence rate of 3.5 per 1,000 live births, often linked to chromosomal abnormalities and environmental factors. Current detection methods face challenges like high demand for fetal cardiologists, vast screening cases, and limitations of 2D ultrasound quality. The proposed hybrid deep learning model, utilizing a dataset of 1,350 2D ultrasound images, advanced preprocessing (EZOO), feature extraction (STA), and selection (IWO), achieves an exceptional 98.5% prediction accuracy. This significantly outperforms state-of-the-art models by 6.4%, boosting diagnostic precision and accelerating crucial decision-making for doctors in prenatal VSD detection.

Understanding VSD & CHD Challenges
Congenital Heart Disorder (CHD) is a leading cause of newborn death and morbidity globally which is predicted to affect 0.8-1.1% of live births worldwide, depending on geography and demographics. Early detection and management of CHD reduce public health system burden. Ventricular Septal Defect (VSD) accounts for 26% of CHDs, with an incidence rate of 3.5 per 1,000 live births. It results from chromosomal abnormalities, genetic predispositions, and environmental factors. Small VSDs are asymptomatic, but larger ones cause heart failure and pulmonary hypertension. Current 2D ultrasound often presents limitations, including image quality issues, fetal positioning, and difficulty in identifying microscopic VSDs. AI and deep learning techniques offer significant improvements in diagnostic precision, reduction of human interpretation variability, and aiding clinical decision-making for VSDs.
Hybrid Deep Learning Approach
Our optimal prenatal diagnosis model utilizes a structured hybrid deep learning pipeline:
- Data Collection: A comprehensive dataset of 1,350 2D ultrasound fetal heart images was gathered over four years (2021–2024) from online sources and a private scanning center, adhering to ethical guidelines. The dataset includes Normal, Perimembranous, Muscular, Inlet, and Supracristal VSD cases.
- Preprocessing: Ultrasound-specific median filter for speckle noise removal, Contrast Limited Adaptive Histogram Equalization (CLAHE) for contrast enhancement, intensity normalization, and resizing.
- ROI Segmentation: The Enhanced Zero-Order Optimization (EZOO) algorithm is employed for optimal Region of Interest segmentation, distinguishing heart chambers and connecting septums under challenging imaging conditions.
- Feature Extraction: A Stacked Triple Attention (STA) mechanism (spatial, temporal, and channel attention) is incorporated to enhance the extraction of crucial features from the images, focusing on important cardiac structures.
- Feature Selection: The Improved Wombat Optimization (IWO) algorithm is used to address data dimensionality issues and select the most important features, reducing model complexity and improving performance.
- VSD Detection & Classification: A Deep Diagonal Recurrent Neural Network (DD-RNN) is used for multi-class classification of VSD types. This architecture effectively models temporal dynamics and structural regularities inherent in fetal heart ultrasound images, ensuring high accuracy and efficiency.
Performance & Clinical Impact
The proposed model demonstrated superior performance:
- Achieved an excellent prediction accuracy of 98.5%, outperforming state-of-the-art models by 6.4%.
- EZOO segmentation achieved a Dice Similarity Coefficient (DSC) of 91.523%, indicating high segmentation accuracy.
- IWO feature selection significantly improved VSD identification and categorization accuracy by reducing data dimensionality.
- The DD-RNN model enhanced overall accuracy by 2.61% over traditional RNN architectures and 3.14% over traditional CNN models.
- The end-to-end GPU inference time is remarkably fast at 5.012 ms, making the model highly viable for real-time clinical application.
- These findings confirm that the model significantly improves diagnostic precision and speeds up doctors' decision-making processes when diagnosing VSD, leading to better patient outcomes in prenatal care.
