“…294 Once values for this index exceed 1.7 at least mild to moderate LV enlargement is likely. However, another potentially useful variable derived from this canine meta-analysis is so-called LV end-diastolic normalized dimension.…”
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
