“…Our study only included CHD cases when they were associated with a VSD. In many case reports, CHD defects are fatal early in life 6 and the diagnosis is made at that time 5,14‐22 . In our study, horses with complex CHD were younger than those with isolated VSD, but still, half of them were ˃1 year old.…”

“…In all, a predominant left‐to‐right shunting of blood through the VSD was found. Two horses had an ostium primum ASD and 1 also had TV atresia, a cleft mitral valve, a VSD and a difference in left ventricle (LV) and RV size, which was compatible with the diagnosis of atrioventricular septal defect with tricuspid atresia and ventricular imbalance 15 …”

“…22 One foal did have a muscVSD together with a reversed PDA, which has been described in a previous case report. 23 Both recorded ASDs were ostium primum ASDs, where the defect is situated in the ventral portion of the atrial septum and above the inlet ventricular septum, 15 and an atrioventricular septal defect was diagnosed in 1 horse.…”

Background: Ventricular septal defects (VSDs) are the most common congenital cardiac defect in horses.Objectives: To identify prevalence, age, breed, and sex distribution of VSD and to describe associated clinical and ultrasonographic findings.Animals: Hospital-based population of 21 136 horses presented to the equine internal medicine department.Methods: Medical records over a 12-year period were reviewed for VSD confirmed by ultrasonography. Age, breed, sex, sport discipline, murmur, clinical signs, outcome, VSD type, VSD size, shunt velocity, cardiac dimensions, concomitant cardiac anomalies, and valvular regurgitations were recorded.Results: From 1894 horses that underwent echocardiography, 54 had a VSD: 42 as an isolated lesion and 12 as part of complex congenital heart disease (CHD). Median age was 5 years (range, 0-26) and 1 year (range, 0-8), respectively. Warmbloods and males were overrepresented. In the isolated VSD group, only 15% had associated clinical signs and most horses had a perimembranous VSD (pmVSD; 36/42). Horses with a pmVSD and clinical signs showed a significantly lower maximal shunt velocity (3.77 vs 5.20 m/s; P < .001), higher VSD/Aortic root (Ao) diameter (0.52 vs 0.38; P = .05), higher left atrium/Ao diameter (1.94 vs 1.22; P < .001), and higher pulmonary artery/Ao diameter (1.15 vs 0.88; P = .005) compared to horses without clinical signs. All horses with complex CHD had clinical signs and abnormal cardiac dimensions. Conclusion and ClinicalImportance: Most isolated VSD were diagnosed only at a later age and were not associated with clinical signs. Horses with complex CHD were more likely to have or develop clinical signs at younger age.

The purpose of this case report is to describe and document a rare anatomical variation of a moderator band located in right ventricle of a stallion referred for cryptorchid castration. During routine pre-anesthetic echocardiography, a thick moderator band was detected crossing the right ventricle. No other cardiovascular abnormalities were identified. Anesthesia and recovery occurred uneventfully. This variation is important not only for anatomy but also for the evaluation of normal heart both during ultrasound and electrocardiographic examination.
