Abstract
The intubation of conventional transesophageal echocardiography (TEE) probes into patients causes serious esophagus irritation, and thus the use of TEE probes in pediatric practice is limited. In this study, we aimed at the development of a special probe which could be inserted through the nasopharyngeal cavity into the esophagus to obtain the same high-quality echocardiography images as those obtained by conventional TEE and improve patients' experience. During the examination, the patients felt relaxed for a longer time and cooperated with the sonographers in the process of cardiac catheterization conducted in the surgery room or the intensive care unit (ICU), resulting in improved accuracy of the diagnosis and timely administration of appropriate treatment. Two years ago, Prof. Xin-fang WANG put theories into practice by inserting the probe through the nasal cavity and pharynx into the esophagus of volunteers to successfully detect the heart and great vessels at the retrocardiac space. Later, Prof. Ming-xing XIE performed the transnasal TEE examination in 12 atrial septal defect (ASD) patients and proved the safety and reliability of this method, which could become a new way for clinical diagnosis and treatment.
