Partial right ventriculectomy using the incised patch technique to treat double chambered right ventricle and chylothorax in a cat.
OBJECTIVE
To report successful surgical treatment of double chambered right ventricle (DCRV) in a cat.


METHODS
Clinical report.


METHODS
Cat with DCRV.


METHODS
DCRV was diagnosed in a 5-month-old male Maine Coon cat using echocardiography and angiocardiography. At 2 years, despite medical therapy, chylothorax developed. A section of the right ventricular free wall that spanned the fibromuscular obstruction was excised under total venous inflow occlusion (TVIO) using the incised pericardial patch technique.


RESULTS
Short-term recovery was complicated by return of chylothorax but this resolved after thoracocentesis and diuretic therapy. Three years after surgery, the cat is free of clinical signs and no longer on any medical therapy.


CONCLUSIONS
Partial right ventriculectomy can be performed under TVIO through an incised pericardial patch.


CONCLUSIONS
DCRV in cat can be successfully treated by partial right ventriculectomy performed under TVIO through an incised pericardial patch.
