Congenital cardiac defects in neonatal foals: 18 cases (1992-2007).

摘要: Background: Literature available regarding congenital cardiac defects in foals is limited to reports of individual cases or small case series. Objective: To describe the clinical, echocardiographic, and necropsy findings breed predilection neonatal foals. Animals: Eighteen <15 days age with 1 more defects. Methods: Medical records diagnosed at William R. Pritchard Veterinary Teaching Hospital were reviewed. Data collected included history, signalment, clinical signs, laboratory data, diagnostic results, outcome. Results: Arabian represented 39% significantly (P= .004) overrepresented (OR = 4.7 [CI: 1.8–12.4]) compared general hospital population. Ventricular septal defect (VSD) (14/18), tetralogy Fallot (5/18), tricuspid valve atresia (4/18) most common identified. A ≥3/6 heart murmur (14/14) accompanied by tachycardia (14/17), tachypnea (17/17), cyanosis mucous membranes (7/16) signs. Concurrent (9/18). Two foals, both VSD, survived for ≥ 8 years after diagnosis was a successful performance horse. Conclusions Clinical Relevance: horses appear have predisposition defects. The presence loud (≥ 3/6), cyanotic membranes, foal should warrant thorough evaluation Foals be closely evaluated concurrent other body systems.
