“…This finding was similar to a case report in a calf described by Nakayama (1985) and to ectopia cordis cervicalis in a calf (where the heart had 2 apices, but was in the pericardial sac) described by Hiraga and Abe (1986), Hiraga et al (1993), and Shiran et al (2010). The calf in our study showed also similar thickness of walls in both ventricles and an atrial structure distinct from the anatomical norm.…”

“…A similarly modified pattern of aortal arch branches (dog type) in cases of cervical ectopia cordis in cattle was described by Hiraga and Abe (1986). In the case of sternal ectopia cordis, the branching pattern of the discussed arteries was defined by Nakayama (1985) as a hybrid pig-cattle pattern.…”

“…Wyrost (1981) detected absence of separation between the systemic and pulmonary circulation in cattle with ectopia cordis. Cranial vena cava in certain cases of ectopia cordis was represented by a two bilateral blood vessel (Hiraga and Abe 1986;Hiraga et al 1993). In our study, and in a similar case described by Nakayama (1985), cranial vena cava, in line with the anatomic norm represented a single blood vessel.…”

Recognition and detailed description of malformations and aberrations in domestic animals may be very useful in cognition of the problem and in creating breeding programs. The aim of this study was to describe a rare case of sternal (pectoral) ectopia cordis in a calf. A female calf of the Limousin breed born in Poland in 2011 was subjected to euthanasia because the heart was situated outside the chest. The carcass of the calf was subjected to anatomical examination in which alterations in cardiovascular system and in the structure of the sternum were observed. Cytogenetic studies were performed to find out if the karyotype of the calf was normal. Elongation of the ascending aorta was observed and the pattern of aortic branching was aberrant similarly to that found in dogs, not cattle. The systemic circulation was found to be linked to pulmonary circulation due to persisting large calibre arterial duct. Each of the ventricles had its own cardiac apex and walls of the ventricles manifested a similar width. The atria were slightly altered. A single, short and dilated blood vessel (pulmonary vein) evacuated its content to the left atrium. Pericardium formed no pericardial sac. Radiogram of the sternum demonstrated a ring-resembling shape and 12 (6 pairs) cartilaginous bars of the sternum (sternebrae). A normal female karytotype (60, XX) indicated that this malformation was not caused by an abnormal number of chromosomes (aneuploidy). Cattle, arterial pattern, sternum, chromosomesEctopia cordis represents a developmental error involving the transposition of the heart outside the chest. Depending on the site to which displacement occurs, it is classified as cervical ectopia cordis (upper or lower ectopia), pectoral or sternal ectopia, and abdominal ectopia (Herzog and Wiedeking 1970;Shiran et al. 2010). Moreover, cases of thoracoabdominal and cervico-pectoral ectopia (Hiraga et al. 1990) were also reported.Manifestation of this developmental error has been detected in almost all livestock species (Hamali and Ashrafihelan 2010). However, vast majority of the reports of ectopia cordis concerned cattle (Wyrost and Radek 1982), and it was less frequent in horses (Hamali and Ashrafihelan 2010). Individuals affected by ectopia cordis in cattle died soon after birth or survived even several years, most frequently till maturity (Murakami et al. 1996).In this study we present a rare case of ectopia cordis of the pectoral (or sternal) type in a Limousin heifer. Materials and MethodsHeart displacement (ectopia cordis) outside the chest was described in a newborn female calf of the Limousin breed born in Poland in 2011 on a commercial farm (birth weight 34 kg). The calf was the third offspring (all three female) of the cow and the delivery, similar to the preceding ones, took place by forces of nature. The sire of the calf was one of two bulls, since a harem mating system was followed on the farm. The calf proved to be viable and healthy, with a preserved sucking reflex. The heart, situated out of the chest, manifested a...

“…The cervical type is the most compatible with life (Hiraga and Abe 1986;West and Payne-Johnson 1987) while calves with the other types died before or early after birth (Eroksuz et al 1998;Schulze et al 2006). Ectopic heart cases can be complicated by different kinds of cardiac and non-cardiac malformations (Hiraga and Abe 1986;Hiraga et al 1993;Eroksuz et al 1998. West and Payne-Johnson (1987) observed tachycardia, increased respiratory rate and a positive jugular pulse in a three-month old calf with cervical ectopia cordis.…”

A female Holstein Friesian calf with inferior cervical ectopia cordis was followed from the 16 th day of age until euthanasia at the age of three months. The heart was located in the lower cervical region and was covered with skin. The calf was presented with normal heart and respiratory rate. A grade II/VI systolic murmur was audible at the heart base when the calf was checked for the first time, but this later disappeared. The ultrasonography revealed that the apex of the heart was directed cranio-ventrally with the left ventricle ventral and slightly to the right side while the right ventricle was dorsal. The results of complete blood count and biochemistry were inside reference intervals. At necropsy the heart was covered with normal pericardium and skin and displaced to the caudal part of the ventral cervical region, just cranial to an enlarged apertura thoracis cranialis. Additionally, the cranial lobes of the lungs were displaced through the enlarged thoracic aperture under the skin on the ventral part of the neck. In conclusion, we suspect that the deformed and enlarged cranial thoracic aperture enabled displacement of the heart and cranial lung lobes to the ventral neck region, because no other abnormalities of the heart and vessels were observed. This is the first case of cervical ectopia cordis reported in Slovenia and this article provides data regarding different aspects of the case (clinics, laboratory, pathomorphology) while also discussing previously published cases of ectopia cordis in cattle.

“…In animals, this anomaly is extremely rare and previous reported cases had accompanied with different anomalies in other organs. Hiraga and Abe reported different anomalies including shortening of the length, widening of the manubrium, hypoplasia of the xyphoid cartilage, the paired appearance of sternebrae in the sternum of Holestein-Friesian calves affected with cervical ectopia cordis by X-ray [16] . Cooper et al found sternal foramina in 6.7% of a large contemporary autopsy population that were usually solitary and located in the body of the sternum.…”
