Causes of right ventricular hypertrophy

    • Diagnosing Right Ventricular Hypertrophy

      Right ventricular hypertrophy (RVH) is the abnormal enlargement of the right ventricle in response to pressure overload, most commonly due to severe lung disease. The right ventricle is considerably smaller than the left ventricle and produces electrical forces that are largely obscured by those generated by the larger left ventricle.

      other causes of isolated right ventricular failure. Treatment effected good control of clinical signs, until acutely decompensated congestive right heart failure led to euthanasia after 4 months. Arrhythmogenic right ventricular cardiomyopathy is a well-described clinical entity in humans, and has previously been documented in 3 male dogs.

Massive hypertrophy (wall thickness ≥ 30 mm) may be associated with high risk of sudden car-diac death [10]. In this case, asymmetric apical wall thickness of the right ventri mm and its posterior cle is 36

The massive lung fibrosis, leukocyte infiltration, and pulmonary hypertension in mice after transverse aortic constriction clearly indicate that congestive heart failure also causes severe lung ...

The increase in wall thickness induced by pressure overload is mainly due to an increase in cardiomyocyte cross-sectional area (5) (Figure 1).

There was a predominance of RVH and LVH in men aged 60-79 years and a higher prevalence in the Brazilian mulatto and Black ethnic groups and in those with adequate nutritional status or overweight and obese individuals.
