Propofol‐dexmedetomidine continuous infusion in a dog with pulmonic stenosis undergoing balloon valvuloplasty

A 6‐month‐old, 4 kg, male pomeranian, was referred for investigations of a heart murmur found during a routine clinical examination. A severe valvular pulmonic stenosis was diagnosed and medical management with atenolol was started. One month later, the dog underwent percutaneous balloon valvuloplasty. Anaesthesia was maintained with propofol‐dexmedetomidine continuous infusion, and a minimally invasive cardiac output monitor was used to assess haemodynamic variations. Intraoperatively, lidocaine was started because the frequency of the premature ventricular complexes increased before ballooning. A reduction in pressure gradient across the pulmonic valve was achieved. No other intraoperative complications were recorded. Recovery from general anaesthesia was uneventful, and the dog was discharged from the hospital 26 hours following the procedure.
