%X The anesthetic management in patients with subaortic stenosis and mitral valve disease should involve intensive monitoring and the anesthesiologist¡¯s main concern is to ensure oxygen delivery and tissue perfusion. Since anesthetic procedures in such patients are rare, there is no previous report about the anesthetic management. A 5.5-year old, 32-kg Boxer, suffering a severe heart disease due to a final stage subaortic stenosis and mitral insufficiency, was anesthetized for an ovariohysterectomy to remove an ovarian tumor that was producing high-volume ascites. Methadone (0.3 mg kg£¿1) was administered intramuscularly (IM) for pre-anesthetic medication, etomidate (1.3 mg kg£¿1) and midazolam (0.2 mg kg£¿1) were used for the induction of anesthesia and after endotracheal intubation, anesthesia was maintained with sevoflurane vaporized in oxygen and air. Fentanyl (5¨C10 ¦Ìg kg£¿1 h£¿1) and paracetamol (15 mg kg£¿1) were administered to improve analgesia. Previous persistent atrial fibrillation was refractory to medication (digoxin, diltiazem, and pimobendan) and continued during the anesthetic procedure. Dobutamine (1.5¨C5 ¦Ìg kg£¿1 minute£¿1) helped to maintain mean arterial blood pressure above 60 mmHg. Epidural morphine (0.1 mg kg£¿1) and incisional bupivacaine (2 mg kg£¿1) were administered at the end of surgery to provide postoperative analgesia. Anesthesia was otherwise uneventful, and recovery was considered excellent
