Studi Kasus Hipertrofi Kardiomiopati, Sinus Takikardia, dan Endokardiosis Anjing Labrador retriever

Abstract

Penyakit jantung sering menyerang anjing. Studi kasus ini bertujuan mengetahui peran pemeriksaan penunjang seperti elektrokardiografi (EKG), radiografi dan ultrasonografi (USG) dalam menegakkan diagnosis hipertrofi kardiomiopati (HCM), sinus takikardia, dan endokardiosis pada anjing Labrador retriever. Anamnesis yang diperoleh ialah anjing mengalami batuk intermiten. Pemeriksaan EKG tidak menunjukkan kelainan pada gelombang P, Q, R, S, dan T, namun terdeteksi adanya peningkatan detak jantung hingga 200 beats per minute. Temuan radiografi tampilan ventrodorsal ialah kondisi kardiomegali. Pemeriksaan USG brightness mode (B-mode) menunjukkan adanya penebalan pada muskulus papillaris dan endokadium. Pemeriksaan USG motion mode (M-mode) menunjukkan adanya peningkatan denyut jantung dan ketebalan left ventricle posterior wall-diastole (LVPWd), serta penurunan ejection time (ET), end diastolic volume (EDV), end systolic volume (ESV), dan stroke volume (SV). Pemeriksaan USG color flow Doppler (CFD) tidak menunjukkan adanya kelainan katup atrioventrikular dan katup semilunaris. Berdasarkan hasil pemeriksaan, hewan didiagnosis mengalami sinus takikardia, endokardiosis, dan HCM.

Heart disease often affects dogs. This case study aims to determine the role of supporting examinations such as electrocardiography (ECG), radiography and ultrasonography (USG) to diagnose hypertrophy cardiomyopathy (HCM), sinus tachycardia, and endocardiosis in Labrador retrievers. The history obtained was that the dog had an intermittent cough. The electrocardiography did not showed any abnormalities in the P, Q, R, S, and T waves, but an increase in heart rate was detected up to 200 beats per minute. The radiographic finding on the ventrodorsal view was cardiomegaly. The Brightness mode (B-mode) ultrasound examination showed an increase in thickness of the papillary muscles and endocardium. Motion mode (M-mode) ultrasound examination showed an increase in heart rate and thickness of the left ventricle posterior wall-diastole (LVPWd), and decreased ejection time (ET), end diastolic volume (EDV), end systolic volume (ESV), and stroke volume (SV). Color flow Doppler (CFD) ultrasound examination did not show any abnormalities of the atrioventricular valve and semilunar valve. Based on the examination results mention above, the animal was diagnosed as/suffered from sinus tachycardia, endocardiosis, and HCM.
