Small Animal Internal Medicine. Eur J Fe,ina 11, Familial hypertrophic cardiomyopathy in Maine Coon cats: Two-dimensional color tissue Doppler imaging detects myocardial dysfunction before occurrence of hypertrophy in a young Maine coon cat.

Journal of Feline Medicine and Surgery, v. Radiographic Interpretation for the Small Animal Clinician. Veterinary Clinics of North America: Left ventricular outflow tract, valve flows and myocardium velocity can be examined by using Doppler studies colour, continuous and pulsed wave and TDI Boon In dogs, it has been used to study the regional myocardial motion concomitantly in several segments and also new indices of systolic left ventricle function, such as systolic rotation, radial, and longitudinal and circumferential St and StR Chetboul et alChetboul et alGriffiths et alWess et al Thus, this review describes the standard and new echocardiographic techniques and their benefits in the diagnosis of feline HCM, and it may assist veterinarians in the diagnosis of the disease, since cats are one of the most popular pets in the world and the demand for specialised care for this species is increasing.

HCM continues to be a challenging disease for veterinarians because it remains the major cause of morbidity and mortality in cats and it is associated with risk of sudden death, heart failure and arterial thromboembolism Chetboul et al a.

Prospective echocardiographic and tissue Doppler imaging screening of a population of Maine Coon cats tested for the A31P mutation in the myosin-binding protein C gene: Pulsed tissue Doppler imaging in normal cats and cats with hypertrophic cardiomyopathy. Right ventricular myocardial involvement in either physiological or pathological left ventricular hypertrophy: Familial hypertrophic cardiomyopathy in Maine Coon cats: Two-dimensional and M-Mode echocardiographic examination of a cat with HCM on right parasternal short axis view at the level of the chordae tendineae.

Many echocardiographic formats are used in clinical practice that involve the reflection of ultrasonic waves from cardiovascular tissues, specialised processing of the returned echoed signals, and the display of this information in recognizable visual or auditory format Bonagura Radial strain and strain rate by two-dimensional speckle tracking echocardiography and the tissue velocity based technique in the dog.


M-mode echocardiography provides measurements of myocardial thickness and ventricular diameter during different periods of the cardiac cycle. Felins determinants of cardiac hypertrophy. J Vet Intern Med 15, A survey of cardiologists and a literature search.

These measurements, primarily of the papillary muscles, left ventricular wall and inter-ventricular septum IVSare very useful for diagnosis of hypertrophy Bonaguraand an inadequate position of leaflets can be observed at the mitral valve level Fox et al Colour M-mode tissue Doppler imaging in healthy cats and cats with hypertrophic cardiomyopathy.

Regarding this tool, a large number of echocardiographic methods are used in feline cardiac diseases Bonagurasuch as conventional echocardiography M-mode, two-dimensional and classic Doppler as spectral and colour flow and new Doppler techniques tissue, strain and strain rate Abbott and MacLeanWess et alBoon Based on the results in humans with HCM, this tool is a promise to the diagnosis and management of this disease in cats.

J Vet Cardiol 13, The aim of this review is to provide an update on information regarding the echocardiographic diagnosis of the disease. The researchers also observed decreased St in hypertrophied and non-hypertrophied myocardial areas, similarly to humans.

Assessment of hypertension in 40 cats with hiperttofica ventricular hypertrophy by Doppler-shift sphygmomanometry. Hypertrophic Cardiomyopathy in Two Kittens. This could be explained by the smaller diameter of the aorta in the M-mode study.

The disease has been attributed to hereditary factors in certain breeds and causal mutations have been discovered in the Maine coon and ragdoll breeds. However, the disease is still a challenge for clinicians because of the difficulty of early diagnosis and the risk of the sudden death of the afflicted animals. Investigation into the use of plasma NT-proBNP concentration to screen for feline hypertrophic cardiomyopathy. The left apical four-chamber view can be used to assess trans-mitral figure 1 and trans-tricuspid flow patterns, while the left apical five-chamber view could be used to obtain the aortic hipertorfica velocity Simpson et alFuentesBoon Journal of Clinical Investigation, v.

Two-dimensional echocardiographic examination of a cat with HCM from the right parasternal short axis view at the level of the papillary muscles.

Schober K, A Todd. Note turbulent flow at systole in left ventricular outflow tract due to obstruction hypertrophy at the sub-aortic area and at left atrium due to mitral insufficiency yellow and red arrows, respectively. Echocardiography is the non-invasive tool of choice for the diagnosis of cardiac diseases in cats. J Am Vet Med Assoc More recent advances in ultrasound technology, such as tissue Doppler image TDITwo-dimensional speckle tracking echocardiography 2D STE cardiomioatia, strain St and strain rate StR imaging, have provided new parameters to assess myocardial function, including regional caddiomiopatia velocities and deformation, ventricular torsion and synchrony Chetboul It has been widely used in veterinary practice to provide a non-invasive assessment of cardiac function Ferasin Some alterations in the mitral valve can be observed with this method, such as inadequate position of leaflets that can cause valve regurgitation or left ventricle outflow tract obstruction LVOTO Ferasin Two-dimensional echocardiographic examination of a fslina with HCM from right paraesternal longitudinal view.

Another study using colour M-mode TDI in cats demonstrated that similar velocity patterns occur in the LVFW of cats when compared with measurements in humans, in which this part of the myocardium shows up alternately as red and blue as it moves towards and away from the velina, respectively.

Grauer, Gregory F.

Papillary muscle hypertrophy can be one of the only signals that indicates the presence of HCM in some cats as well as human beings figure 3 Kobashi et alKittleson et alAdin and Diley-Poston Hypertrophic cardiomyopathy is associated with more severe left ventricular dyssynchrony than is hypertensive left ventricular hypertrophy. Palavras-chave cardiopatia; hipertrofia; gatos. Colour M-mode TDI allows the calculation of myocardial velocity gradient MVGwhich describes the spatial distribution of trans-myocardial velocities from the endocardium to the epicardium.
