Mitral valve insufficiency is frequently observed due to SAM, because abnormal leaflets in the valve result in incomplete cooptation at systole AbbottSchober and Todd figure 4A and 4B. Echocardiography is the non-invasive tool of choice for the diagnosis of cardiac diseases in cats. End-diastolic wall thickness of the IVS and the left ventricular posterior wall LVPW must be measured in the basal and mid-ventricular segment of the respective myocardial wall using the right parasternal long-axis view Wess et al or right short-axis view Fox et al J Small Anim Pract 49, The diagnosis of HCM was confirmed by conventional echocardiography one year after the first examination.

Definitive diagnosis of feline HCM is mainly based on echocardiography, which is the method of choice to observe structural changes and evaluate pathological dysfunctions Brizard et alWess et al A survey of cardiologists and a literature search.
Prevalence of hypertrophic cardiomyopathy in a general population of young adults: 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 flow velocity Simpson et alFuentesBoon cardiomoopatia Vet Clin Small Anim 40, Journal of the American Veterinary Medical Association, v. Report on the definition and classification of cardiomyopathies.
Echocardiographic assessment of spontaneously occurring feline hypertrophic cardiomyopathy. Some clinical investigations of feline HCM have used an end-diastolic wall thickness gipertrofica to or exceeding 6. Tierarztl Prax 24, The LA size felia been associated with ventricular filling pressures in patients with diastolic dysfunction, and this finding is very important to feline cardiology.

One study demonstrated that sedation using a combination of acepromazine and hydromorphone does not affect two-dimensional 2D and M-mode measurements, despite the mild increase in the heart rate Campbell and Kittleson Schweiz Arch Tierheilk It is considered the gold standard exam for feline HCM Bonagura Population characteristics hipertrofiica survival in referred cats with hypertrophic cardiomyopathy to It has been widely used in veterinary practice to provide a non-invasive assessment of cardiac function Ferasin Feline HCM is a disease of the ventricular myocardium characterised by mild-to-severe primary concentric hypertrophy.

It is an obstructive form of HCM that may cause a turbulent blood flow that could be identified using the colour-flow Doppler Ferasin et al Many echocardiographic formats are used in clinical hipertroica 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 Investigation into the use of plasma NT-proBNP concentration to screen for feline hypertrophic cardiomyopathy.
Journal of Small Animal Practice, v. HCM is one of the most common cardiac diseases in cats.
Chetboul et al a using affected cats and carriers of dystrophin-deficient hypertrophic muscular dystrophy as a model of HCM, demonstrated that TDI could detect radial and longitudinal LVFW dysfunction in all cats even though none of the animals presented significant left myocardial hypertrophy. Although, in the felinq, HCM diagnosis is mainly obtained using conventional echocardiography as M-mode and 2D measurements, these could make difficult to identify myocardial alterations in animals at early stages of the disease.
Advanced techniques in echocardiography in small animals.
Given those findings, 2D STE could in the future be useful in the diagnosis of feline HCM; therefore, studies of the use of this tool in cats with HCM are needed to evaluate its effectiveness in the diagnosis of the disease. Right ventricular myocardial involvement in either physiological or pathological cardioniopatia ventricular hypertrophy: New echocardiographic techniques such as tissue Doppler imaging 2-dimensional colour, colour M-mode, cardiomiopatai modestrainand strain rate have proven to be effective in the early diagnosis of myocardial dysfunction, even in the absence of hypertrophy in conventional echocardiography.
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 Spectral pulsed-wave TDI is a technique that measures myocardial velocity, which has good temporal resolution Simpson et al and has been used to assess the velocities within the feline myocardium Chetboul et al aChetboul et al bSimpson et al figure 6.
