Usefulness of echocardiographic right ventricular measurements in estimating right ventricular hypertrophy and right ventricular systolic pressure

Phenotypic Variation of Familial Hypertrophic Cardiomyopathy Caused by the Phe¹¹⁰→Ile Mutation in Cardiac Troponin T

“…The LV ejection fraction was calculated according to Simpson’s rule [20]. Diagnosis of right ventricular hypertrophy (RVH) was based on a right ventricular (RV) free wall thickness of >7 mm in the subcostal view [21]. The type of LVH [22]and ventricular morphology [23]were classified according to previously described criteria.…”

Guidelines for the Echocardiographic Assessment of the Right Heart in Adults: A Report from the American Society of Echocardiography

“…A espessura da parede VD é uma medida útil para a avaliação de hipertrofia de VD, geralmente como resultado de sobrecarga da PSVD. [16][17][18] Aumento da espessura do VD pode ser encontrado em pacientes com miocardiopatia hipertrófica e infiltrativa, assim como em pacientes com hipertrofia significativa do VE, mesmo na ausência de HP. 19 A espessura da parede livre do VD pode ser medida ao final da diástole pelo modo M ou pela ecocardiografia 2D a partir da janela subcostal, preferencialmente ao nível da ponta da cúspide anterior da valva tricúspide ou nas janelas paraesternais esquerdas.…”

Increased Right Ventricular Wall Thickness in Hypertrophic Cardiomyopathy

“…Prakash [6,7] and Prakash and Matsukubo [8] dem onstrated a good correlation between right ventricular anterior wall thickness as measured by M-mode para sternal view and necropsy studies, with a sensitivity and specificity of 93 and 95% respectively for the échocar diographie diagnosis of right ventricular hypertrophy. Later studies have evaluated the right ventricular wall thickness in patients with left ventricular hypertrophy associated to aortic stenosis [10,11], hypertension [10,11], congestive cardiomyopathy [11], right ventricular volume pressure overload [9] and amyloidosis [14], Although in a selected group of individuals the thick ness of right ventricular myocardium can be studied at different levels [15], the usual way to determine it is through its free wall in the parasternal or subcostal views with M-mode.…”

“…It is concluded that right ventricular hypertrophy is a common occurrence in patients with hypertrophic cardiomyopathy, without correlation with the degree of left ventricular hypertrophy. It does not pre dominate in any particular type of hypertrophic cardiomyopathy, but it predominates in patients with higher right ventricular systolic and mean pulmonary artery pressures and in those with signs of congestive heart failure.Prakash [6,7], Prakash and Matsukubo [8], and Matsukubo et al [9] have shown that there is a good correla tion between right ventricular thickness as estimated with M-mode echocardiography and necropsy measure ments. On the basis of these findings, other authors [ 10, 11] have analyzed the degree of thickening of right ven tricular anterior wall in patients with left ventricular pressure overload and they have found that the right…”
