Cutting balloon catheterization for interventional treatment of cor triatriatum dexter: 2 cases.

Abstract

Cutting balloon dilatation was performed successfully in two dogs with cor triatriatum dexter and clinical signs of ascites. The cutting balloon catheter uses incisional microtomes embedded in a balloon catheter. During balloon expansion, these microtomes incise the adjacent tissue, decreasing circumferential wall stress. This theoretically reduces both the likelihood of fracturing the adjacent tissues in an uncontrolled manner and the potential neoproliferative response to standard balloon dilatation and the subsequent incidence of re-stenosis. In both cases described, clinical signs resolved completely following cutting balloon dilatation of the anomalous membrane. Based on the outcome of these 2 cases, cutting balloon dilatation appears to be a viable treatment option for dogs affected with cor triatriatum dexter.
