Cor triatriatum dexter Complicated with Pulmonic Stenosis and Patent Foramen Ovale in A Pitbull Terrier Puppy

Abstract : A 2-month-old intact male Pitbull terrier (weighing 1.01 kg) were referred with primary complaints of severeabdominal distension, exercise intolerance, retarded growth, yellow nasal discharge and anorexia. Diagnostic imagingstudies found enlarged right atrium partitioned by abnormal membrane, severe pulmonic systolic jets (5.66 m/s of peakvelocity) and right-to-left blood shunt at the inter-atrial septum. Based on clinical and diagnostic findings, the casewas diagnosed as cor triatriatum dexter complicated with severe pulmonic stenosis and right-to-left shunted patentforamen ovale. Either surgical or interventional therapy has not been attempted, because of unstable patient’s condition. Using blood transfusion, oxygen supply and cardiac medications (i.e., sildenafil, spironolactone, enalapril), the dogwas recovered.
