Cardiomiopatía hipertrófica felina: enfoque ecocardiográfico
Another study using colour M-mode TDI in cats demonstrated that similar velocity patterns occur in the LVFW of cats when compared with measurements hipetrofica humans, in which this part of the myocardium shows up alternately as red and blue as it moves towards and away from the transducer, respectively.
J Vet Cardiol 9, LA can be accessed by M-mode measurements, though limitations to this technique exist: Definitive diagnosis of feline HCM is mainly cardiomoipatia on echocardiography, which is the method of choice to observe structural changes and evaluate pathological dysfunctions Brizard et alWess et al Tierarztl Prax 24, J Vet Intern Med 17, Assessment of the repeatability of feline echocardiography using conventional echocardiography and spectral pulse-wave Doppler tissue imaging techniques.
Interrelations of clinical manifestations, pathophysiology, and therapy 1. Right ventricular myocardial involvement in either physiological or pathological left ventricular hypertrophy: In addition, the presence of biphasic characteristics in the early diastolic movement in the LVFW of cats was observed.

Other techniques include St and StR, and these measurements were introduced into clinical practice to evaluate regional myocardial deformation magnitudes and rates Wess et al Small Animal Practice, v. J Feline Med Surg 13, J Vet Cardiol 13, Two different planes must be obtained, one at the level of the papillary muscles in order to measure the IVS and left ventricular free wall LVFW thicknesses in end-diastole and the other at the level of the mitral valve to determine the presence or absence of systolic anterior motion SAM Boon Journal of Veterinary Internal Medicine, v.

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: Finally, assessment of RV morphology and function is very difficult in M-mode studies Ferasin Pulsed-wave and colour M-mode are TDI techniques that have been demonstrated to be sensitive tools to detect even mild forms of HCM, providing an early diagnosis of the disease MacDonald et alKoffas et alKoffas et al 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.
In recent years, standard trans-thoracic echocardiography has become a primary imaging tool for the diagnosis and management of small animal cardiovascular diseases Chetboul Left ventricular outflow tract, valve flows and myocardium velocity can be examined by using Doppler studies colour, continuous and pulsed wave and TDI Boon Many echocardiographic formats are used in clinical practice that involve the reflection of ultrasonic waves from cardiovascular tissues, specialised processing of the returned hipertroficca signals, and the display of this information in recognizable visual or auditory format Bonagura Images of papillary muscle, mitral valve, aortic root and LA should be obtained by means of 2D and M-mode techniques.
