Echocardiography is a standard diagnostic tool for assessment of cardiac functions and cardiovascular diseases in dogs, however published echocardiographic measurements have varied widely based on dog breeds. The objective of this prospective reference interval study was to provide breed-specific echocardiographic values for healthy French Bulldogs. A total of 42 healthy French Bulldogs of both sexes (23 females and 19 males) were sampled. Furthermore, measurements for a control group (n = 16) were also conducted in four other dog breeds (Cocker Spaniel [n = 2], Cavalier King Charles Spaniel [n = 4], Terrier [n = 5], and Crossbreed [n = 5]). Standard M-mode, two-dimensional (2D), pulse wave (PW) Doppler, and tissue Doppler imaging (TDI) echocardiographic measurements were obtained from healthy French Bulldogs. The M-mode echocardiographic data obtained from French Bulldogs were compared to the data obtained from the control group. The left ventricular internal dimension at end-diastole (LVIDd; cm)/body surface area (BSA) (m 2) ratio for the study group was 3.35/0.53 = 6.32. Left ventricular measurements for French bulldogs and internal dimension at end-systole (21.23 ± 3.50 mm) and at end-diastole (33.50 ± 4.12 mm) were found to be significantly higher (P < .001) compared to control group values (left ventricular internal dimension at end-systole [LVIDs]; 17.46 ± 2.85 mm, LVIDd; 27.16 ± 4.20 mm, respectively). A significantly positive correlation in the French Bulldog group was noted between body weight and M-mode measurements (EPSS, IVSd, IVSs, LVIDd, LVIDs, and LVPWd). French bulldogs had a greater systolic and diastolic left ventricular volume than the control group. As a result, values reported in this study could be used as specific reference ranges in French Bulldogs.

“…Despite no significant increase in Am, the Em/Am ratio was <1 on the IVS side at Day 56 and <1 on the LVFW side at Day 84. Reduced E/A ratio indicate abnormal LV flaccidity, but these changes may be absent or obscure in the early stages of cardiac disease [ 12 ]. The IVS side of the mitral annulus is more appropriate for assessing cardiac function than the LVFW side [ 10 ].…”

This study aimed to assess the structural and functional effects of long-term hyperglucocorticoidemia on canine myocardium and compare these parameters with histopathological changes. Twelve healthy male beagle dogs were enrolled and assigned to the high-dose prednisolone (P; n = 6) and control (C; n = 6) groups. The P group was treated with 2 mg/kg of prednisolone BID for 84 days. Clinical parameters were measured using echocardiography and non-invasive systolic blood pressure (SBP) measured before the initiation of synthetic corticosteroids and at 7, 28, 56, and 84 days after the start of medication. For histological evaluation, cardiovascular tissue was harvested from dogs in groups P (at the end of the medication period) and C (scheduled to be euthanized for unrelated reasons). In the P group, clinical changes including thickening of the left ventricular free wall (LVFW) and interventricular septum (IVS), decreased left ventricular (LV) diastolic function, and increased SBP were observed after the start of medication. During histological evaluation, fibrosis was observed in the LVFW and IVS in the P group. Furthermore, decreased glucocorticoid receptor (GCR) levels were observed in the LVFW, right ventricular free wall (RVFW), and IVS and increased mineralocorticoid receptor (MCR) levels were observed in the LVFW and RVFW in the P group compared with those in the C group. In conclusion, fibrosis may cause LV structural and functional abnormalities in dogs with hyperadrenocorticism. Furthermore, GCR downregulation and upregulated MCR might influence the myocardial fibrosis.

Myxomatous mitral valve disease (MMVD) is the most common acquired valvular disease in small breed older dogs that is responsible for congestive heart failure Echocardiography is the method of choice to make the diagnosis, classify patients, and monitor treatment. The aim of this study is to evaluate the value of pulsed Doppler mitral flow and tissue Doppler to assess cardiac function in dogs with chronic degenerative mitral disease, stage C. Material and methods: Five dogs with MMVD stage C and 5 healthy dogs of similar ages and weights were included in the study. Data about dogs identification and the following echocardiographic parameters were included in the study: LA/Ao ratio, transmitral flow velocities (E, A and E/A ratio), mitral annulus velocities (lateral and medial) and radial short-axis velocities by tissue Doppler (S´, E´ and A´), E/A ratio E´ and functionality parameters of the right ventricle (systolic excursion of the plane of the tricuspid annulus-TAPSE-, and tissue Doppler of the lateral tricuspid annulus (S´, E´ and A´)). Results: eleven of the 19 parameters evaluated were different from significantly between healthy and diseased animals: elevation of the AI/Ao ratio, Vmax E, E/A ratio, E´ in the three regions, S´ (lateral and medial), E/E´ ratio, E´ and S´ of the ventricle. Conclusions: the elevation of tissue Doppler parameters indicates that the functionality of both the left and right ventricles is maintained in dogs with stable MMVD stage C. These dogs present very high left ventricular filling pressures (Vmax E and E/A ratio). La enfermedad mitral degenerativa crónica (EMCD) es la valvulopatía adquirida más frecuente en perros de raza pequeña y edad avanzada que es responsable de insuficiencia cardiaca congestiva. La ecocardiografía es el método de elección para efectuar el diagnóstico, clasificar a los pacientes y monitorizar el tratamiento. El objetivo de este estudio es examinar la utilidad del Doppler pulsado del flujo transmitral y Doppler tisular para evaluar la funcionalidad cardiaca en perros con enfermedad mitral degenerativa crónica en estadio C. Materiales y métodos: Se incluyeron en el estudio 5 perros con EMDC en estadio C y 5 perros sanos de edades y pesos similares. Se seleccionó de los historial clínico de cada perro los datos de la reseña y siguientes parámetros ecocardiográficos: ratio AI/Ao, velocidades flujo transmitral (E, A y ratio E/A), velocidades del anillo mitral (lateral y medial) y radial en eje corto mediante Doppler tisular (S´, E´ y A´), ratio E/E´ y parámetros de funcionalidad del ventrículo derecho (excursión sistólica del plano del anillo tricúspide-TAPSE-, y Doppler tisular del anillo tricúspide lateral (S´, E´ y A´)). Resultados: once de los diecinueve parámetros evaluados resultaron diferentes de forma significativa entre animales sanos y enfermos: elevación ratio AI/Ao, Vmax E, ratio E/A, E´ en las tres regiones, S´ (lateral y medial), ratio E/E´, E´ y S´ del ventrículo derecho. Conclusiones: la elevación de los parámetros del Doppler tisular indica que la funcionalidad tanto del ventrículo izquierdo como derecho esta mantenida en perros con EMCD estadio C estable. Estos perros presentan presiones de llenado del ventrículo izquierdo muy elevadas (Vmax E; ratio E/A).
