“…Aortic rupture at the location of the aortic arch, near the ligamentum arteriosum in combination with fistulation towards the pulmonary artery is less common than aortic root rupture (Fig ). The condition has been described in three young Warmblood horses aged 3–4 years , all other reported cases have been in Friesians. Rupture, sometimes with dissection of aortic aneurysm extending along the ascending aortic arch occurs with or without the development of periaortic haematoma or transverse rupture in the pulmonary trunk .…”

“…The condition has been described in three young Warmblood horses aged 3–4 years , all other reported cases have been in Friesians. Rupture, sometimes with dissection of aortic aneurysm extending along the ascending aortic arch occurs with or without the development of periaortic haematoma or transverse rupture in the pulmonary trunk . Friesian horses consistently develop transverse rupture near the ligamentum arteriosum and, in the majority, there is aortopulmonary fistulation with pseudoaneurysm, a blood‐filled cavity lined by endothelium and supported by granulation tissue originating from the area of rupture.…”

The aorta can rupture at the aortic root or aortic arch. In most breeds, the aortic root is the likely site and rupture leads to aortocardiac fistula with communication between the aorta and the right atrium, right ventricle and/or the interventricular septum. There is a high prevalence of aortic rupture in young Friesian horses and rupture occurs at the aortic arch with pseudoaneurysm and potentially aortopulmonary fistulation. Echocardiographic and post-mortem techniques must be adapted to identify aortic arch rupture that is not generally identified with standard approaches. Given the narrow genetic base of the Friesian breed and the significant differences found in extracellular matrix composition and metabolism between Friesians and Warmbloods, genetic factors are likely to contribute to the condition in the Friesian breed.

“…In horses, aortic aneurysm, which is dissection and rupture or fistula of the aorta into a cardiac chamber or vessel, also referred to as aortic root disease, has been reported more frequently. [8][9][10][11][12] Aortic root disease has been described more frequently in stallions and geldings.…”

A 3-year-old male, castrated, miniature pinscher weighing 9 kg was presented to the University of Zurich Veterinary Teaching Hospital Cardiology Service for evaluation of lethargy, a newly recognized cardiac murmur, and labored breathing. For the previous 3 days, the dog had been progressively reluctant to move and breathing had become labored. Before the current presentation, the dog had always been in excellent health.On admission, the dog was in sternal recumbency, profoundly lethargic, and showed expiratory dyspnea. Diffuse petechiation was visible on the skin and mucous membranes. Heart and pulse rate were 160 beats per minute and irregular, pulse quality was weak, and rectal temperature was 37.1uC (98.8uF). On auscultation, no respiratory or cardiac sounds were heard on the left side and muffled sounds were heard on the right side with a continuous heart murmur, grade 3/6. The jugular veins were distended and abdominal palpation disclosed hepatomegaly and ascites.Laboratory abnormalities on presentation included severe thrombocytopenia (11,000/mL; reference range, 130,000-394,000/mL), hypoproteinemia (43 g/L, reference range: 56-71 g/L), hypoalbuminemia (22 g/L, reference range: 29-37 g/L), hyponatremia (136 mmol/ L; reference range, 152-159 mmol/L), and hyperkalemia (5.4 mmol/L; reference range, 4.3-5.3 mmol/L). A coagulation profile was normal.An ECG indicated sinus tachycardia with single ventricular premature complexes and non-sustained ventricular tachycardia with a left bundle branch block pattern. The QRS complexes during sinus tachycardia were consistent with right ventricular enlargement and the ST segments were depressed in leads I, II, and aVF and increased in lead aVR.Thoracic radiographs revealed marked pleural effusion, moderate right heart enlargement, diminished pulmonary vasculature, engorged caudal vena cava, hepatomegaly, and ascites. Analysis of abdominal and pleural fluids indicated that they were modified transudates.On 2-dimensional and M-mode transthoracic echocardiography, a the right ventricle (RVDd, 2.45 cm) and right atrium (RA, 4 cm) appeared markedly dilated with flattening of the interventricular septum. The left ventricle was hypovolemic (LVDd, 1.4 cm). In the main pulmonary artery, a membranous structure that originated laterally slightly above the pulmonary valve annulus was bulging into the lumen (Fig 1a). An echodense structure suggestive of a thrombus at the site of the pulmonary artery bifurcation completely occluded the left pulmonary artery. Color Doppler echocardiography indicated moderate tricuspid insufficiency (TI), mild pulmonic insufficiency (PI), and continuous turbulent flow from the descending aorta to the main pulmonary artery through a patent ductus arteriosus (PDA). Furthermore, the systolic outflow signal above the pulmonary valve was only a narrow turbulent jet that passed medially to the described membrane. Behind the membrane, there was no systolic flow but only diastolic blood flow in the main pulmonary artery towards the pulmonary valve (Fig 1b). Sp...

“…Einleitung ln den letzten drei Jahrzehnten sind in der Literatur nur zwei Fälle von Aneurysmen im Bereich der Aortenwurzel und des Aortenbogens beim Pferd beschrieben (Holmes et al 1973;Derksen et al 1981). Aneurysmen des Aortenbogens sind häufige Befunde beim Wolf durch Infektionen mit Spirozerca lupi (/voghli 1977;Thornton et al 1974) und bei Syphillisinfektionen des Menschen (Gore andHirst 1973', Sabrston 1977).…”

ZusammenfassungBei zwei Reitpferden (6 und 7jähriger Wallach) wurden mit bildgebenden Verfahren (Ultraschall, Röntgentechnik) Aneurysmen der Aortenwurzel und des Aortenbogens dargestellt. Sonographisch wurde in einem Fall eine hochgradige EMeiterung der Aortenwuzel (Fall 1) und in einem anderen Fall eine Lageveränderung des intraperikardialen Anteiles der Aortenwurzel festgestellt. Röntgenologisch konnte im Fall des dilatierten Aortenbogens (Fall 2) im Vergleich zur Abbildung der Aorta eines gesunden fferdes eine deutliche Vergrößerung dieser Struktur festgestellt werden. lm Fall 1 wird das Vorliegen eines Aneurysma verum spontaneum als wahrscheinlich angesehen.Schlüsselwörter: Pferd, Echokardiographie, Röntgendiagnostik, x-ray examination, Pathomorphologie Echocardiographic and radiographic imaging ot aortic root and aortic arch aneurysm in the horse Aneurysm of the aortic root and the aortic arch were demonstrated in two warm-blooded geldings (6 and 7 years old) by diagnostic ultrasound and radiology. In case one a severe dilatation of the aortic root and in case t/vo an abnormal position of the endopericardial part of the aortic root was detected with diagnostic ultrasound. In the second case radiology revealed an enlargement of the dilated aortic aneurysm. ln the first case an aneurysm verum spontaneum is probable.
