ABSTRACT

<p><b>OBJECTIVE</b>To design a device for direct vision intracardiac operation without cardiopulmonary bypass, and assess its applicability preliminarily.</p><p><b>METHODS</b>The device was designed according to the clinical needs of intracardiac operation and used in operations for repairing atrial septal defect in 5 ex vivo porcine heart models. The practical applicability of this device was thoroughly tested and the results of the operations were evaluated.</p><p><b>RESULTS AND CONCLUSION</b>Direct vision operation for repairing atrial septal defect was successfully performed using this device, which can be a well applicable in some intracardiac operations, but its clinical effects need further evaluation.</p>
