N2 - Objective: To present the results of investigation of a new application of invasive ultrasonography - ultrasound cardioscopy, a procedure in which a self-contained ultrasound device is capable not only of producing an under- blood field of view but also of delivering diagnostic and therapeutic tools. Design: Twenty adult mongrel dogs were studied with the ultrasound cardioscopy device during experimental catheter ablation procedures. Material and Methods: A rigid prototype probe, 34 cm long and 8 mm in diameter with a 7-MHz side-viewing transducer at the tip and an 8-F diameter tool delivery port, was introduced through the right external jugular vein into the right heart chambers. Remote and device-directed ablation procedures were monitored. Subsequently, the canine hearts were excised and examined. Results: The self-contained cardioscopy device with a contained ablation catheter could both direct and visualize a specified ablation injury. Under- blood observation of the details of the ablation procedure was possible. Although a learning curve existed for appropriate manipulation of the device, inspection of the excised hearts showed that the size of the injury was accurately predicted with use of ultrasound cardioscopy. Conclusion: Ultrasound cardioscopy is a promising means of performing precise under- blood diagnostic and therapeutic maneuvers.
