İki Boyutlu Benek Takibi Ekokardiyografinin Veteriner Kardiyolojide Kullanımı

Öz

Bu çalışmanın amacı sağlıklı kedi ve köpeklerde yapılan iki boyutlu benek takibi ekokardiyografide, kısa eksen papillar kas seviyesinde radiyal, sirkümferensiyal gerilim ve gerilim hızı ölçümlerinin yapılarak bu tekniğinin tanıtılmasıdır. Ankara Üniversitesi Küçük Hayvan Eğitim ve Araştırma Hastanesi’ne kardiyolojik muayene amacıyla getirilen kardiyolojik yönden sağlıklı kediler (n = 5) ve köpeklerin (n = 5) kaydedilen ekokardiyografi görüntüleri retrospektif olarak analiz edildi. Muayene sağ ve sol lateral pozisyonda ve hayvanlar sedasyona alınmadan yapıldı. Kediler için sırasıyla ortalama zirve sistolik radyal gerilim, radyal gerilim hızı, sirkümferensiyal gerilim, sirkümferensiyal gerilim hızı 24.47 ± % 1.22, 0.29 ± 0.20 s-1, -15.33 ± % 2.56, 0.05 ± 0.27 s-1 ölçülürken, köpekler için bu ortalama değerler sırasıyla 39.33 ± % 14.02, -0.47 s-1 ± 0.55 s-1, -23.13 ± % 1.53, -0.63 s-1 ± 0.18 s-1 olarak ölçülmüştür. Konvansiyonel ekokardiyografi ile karşılaştırıldığında benek takibi ekokardiyografi tekniğinin sol ventrikülün sistolik fonksiyonunu belirlemesi noktasında daha detaylı bilgi sağlaması ve muayene süreleri arasında çok ciddi bir fark olmaması gibi sebeplerle iki boyutlu benek takibi ekokardiyografinin rutin ekokardiyografik incelemeler arasına dahil edilebileceği düşünülmektedir.

The Use of Two Dimensional Speckle Tracking Echocardiography in Veterinary Cardiology

Abstract

The aim of this study is to present short-axis radial and circumferential strain and strain rate measurements by speckle tracking echocardiography technique in healthy cats and dogs. The study was performed at Small Animal Training and Research Hospital, Ankara University. Retrospective data from cats (n=5) and dogs (n=5), which are applied to the animal hospital for cardiological examination, were analyzed. Two-dimensional speckle tracking echocardiography was performed without sedation, and patients were manually restrained in the right and left lateral positions. Peak systolic radial strain, radial strain rate, circumferential strain, circumferential strain rate means were 24.47 ± 1.22%, 0.29 ± 0.20 s-1, -15.33 ± 2.56%, 0.05 ± 0.27 s-1 respectively for cats and were 39.33 ± 14.02%,-0.47s -1 ± 0.55 s-1, -23.13 ± 1.53%, -0.63 s-1± 0.18 s-1 respectively for dogs. It is thought that speckle tracking echocardiography can be included in routine echocardiographic examinations because this technique provides detailed information for determining the systolic potential of the left ventricle and the examination time is not much different compared to conventional echocardiographic examinations.
