The evaluation of echocardiographic findings on sports horses

Bu çalışmanın amacı, spor atlarında (n = 79) kan hemodinamiği, sol ventrikül kontraktibilitesi, sol ventrikül ve atrium iç çaplarını, aort ve atrioventriküler kapakların fonksiyon bozukluklarını değerlendirmekti. Atrioventriküler (AV) kapakların anatomik yapısı ve kapak düzeyindeki kan hemodinamiği, kardiak yapıların ölçümleri, göğüs kafesinin sağ ve sol tarafından belirlenen 3,4,5 odacık görüntüsünde M-mod, 2-D görüntüleme, pulsed-wave (PW) ve renkli Doppler ile elde edilen bulgular doğrultusunda değerlendirme yapıldı. Kardiak hastalık bulgusu olmayan 42 atta, interventriculer septum kalınlığı diyastolde 32.3±5 mm ve sistolde 41.4±7 mm; sol ventriküler iç çap diyastolde 122.3±6 mm ve sistolde 74±4 mm; sol ventriküler serbest duvar kalınlığı diyastolde 26.9±4 mm ve sistolde 34.8±8 mm; aortik iç çap 88.1±6 mm; sol atriumun iç çapı 63.1±3 mm; fractional shortening % 40.4±5 ortalama değerleri elde edildi. Kardiak hastalık tanısı konulan 37 atın 7’sinde sol atrioventriküler dilatasyon, 5’inde sol atrial dilatasyon, 3’ünde azalmış fractional shortening (19-28%); 10’unda sol ventriküler serbest duvarda regional hipokinezi. 7’sinde perikardial effüzyon ve 5 olguda da E:A oranı 1 değerinin altında belirlendi. Sonuç olarak, bu saha çalışması, belirgin klinik semptomları olmayan kardiak hastalıkların belirlenmesinde ekokardiografik parametrelerin önemini ortaya koymaktadır.

The aim of this study was to evaluate the findings of blood hemodynamics, left ventricular contractility, internal diameter of the left ventricle and atrium, aort and atrioventricular valve function disorders in the sport horses (n = 79). The anatomical structure and blood hemodynamics of atrioventricular (AV) valves, measurements of cardiac structure were determined using M-mode, 2-D, pulsed-wave (PW) and color Doppler findings obtained from the right and left chest wall in the 3,4 and 5 chamber views. In 42 horses without cardiac diseases findings, average interventriculer septum thickness in diastole and systole was 32.3±5 and 41.4±7 mm; left ventricular internal diameter in diastole and systole, 122.3±6 and 74±4 mm; left ventricular free wall thickness in diastole and systole, 26.9±4 and 34.8±8 mm; aortic internal diameter, 88.1±6 mm; left atrium internal diameter, 63.1±3 mm and fractional shortening, 40.4±5%. Of 37 horses diagnosed with cardiac diseases, 7 horses had left atrioventricular dilatation; 5 had left atrial dilatation; 3 had low fractional shortening (19-28%); 10 had regional hypokinesia on left ventricular free wall and 7 had pericardial effusion as well as in 5 cases, the E:A ratio was below 1. In conclusion, this screening study reveals importance of echocardiographic parameters in detection of cardiac diseases without exhibiting major clinical symptoms.
