If a patient exhibits some ventricular septal defects, it is possible for hoarseness to occur, as this condition is a type of congenital heart disease.

If a patient frequently experiences hoarseness, it might be caused by congenital heart disease, but chronic pharyngitis or laryngitis, which can also cause hoarseness, should not be ruled out. Additionally, conditions like vocal cord polyps or deeper diseases can lead to hoarseness. However, it is important to differentiate these from normal diseases. If the issue is solely a ventricular septal defect, surgical treatment can be recommended for the patient, which can achieve a complete cure. Attention should also be paid to maintaining a healthy diet.
