Right Ventricular Dilatation


Presentation

  • The exclusion of a large akinetic RVOT area during reoperation of patients presenting with severe post-repair right ventricular dilatation was investigated.[ncbi.nlm.nih.gov]
  • Idiopathic myocarditis associated with such unusual features is relatively rare, and may present problems in differentiation from other congenital heart diseases causing dilatation and dysfunction of the right ventricle.[ncbi.nlm.nih.gov]
  • The present study examined the clinical significance of echocardiographic right ventricular dilatation in patients with right ventricular infarction.[ncbi.nlm.nih.gov]
  • OBJECTIVE: The aim of the present study was to identify the factors associated with right ventricular (RV) dilatation and dysfunction in patients with chronic pulmonary regurgitation (PR) after repair of tetralogy of Fallot.[ncbi.nlm.nih.gov]
  • Pediatric patients usually have no symptoms but patients over 40 years of age are symptomatic at presentation [ 5 ].[omicsonline.org]

  • Causes of right chambers dilatation include pressure overload, volume overload, and myocardial dysfunction, which may be secondary to ischemic heart disease or to primary cardiomyopathies (mainly ARVC) (1).[escardio.org]
Renal Impairment
  • Delays in diagnosis have been linked to issues with imaging (wait times, schedules), contrast in the setting of renal impairment, and poor IV access.[emultrasound.sdsc.edu]

Prognosis

  • Abstract The prognosis of multidetector computed tomography (MDCT) assessed right ventricular dilatation (RVD) is unclear in patients with pulmonary embolism (PE) and a simplified Pulmonary Embolism Severity Index (sPESI) of 0.[ncbi.nlm.nih.gov]
  • Our outcome figures suggest a guarded prognosis be given during counseling of parents of fetuses with right heart dilatation.[ncbi.nlm.nih.gov]
  • The prognosis of pulmonary hypertension (PH) depends upon the functional capacity of the right ventricle.[jscimedcentral.com]
  • The study of life prognosis in patients with 2 forms of DCM showed that 5-year mortality of patients was about 50%.[ijbm.org]

Etiology

  • Etiology Primary hypertrophic cardiomyopathy ( 60–90% of cases) Most common hereditary heart disease Most commonly due to mutations in genes encoding myosin heavy chain causes disorganized myocyte architecture characterized by myofibrillar disarray and[amboss.com]
  • The left ventricular compromise in the proband and in his father may have two different etiologies (in the case of the proband’s father DCM could be secondary to hypertension and valvular disease), but it may also be possible that they have a familial[escardio.org]
  • Myocarditis should also be suspected when patients have a history of acute or subacute development of left ventricular dysfunction without an apparent etiology; when a patient presents with pericarditis (infectious or idiopathis) with cardiac biomarker[clevelandclinicmeded.com]

Prevention

  • OBJECTIVES: We hypothesize that concomitant tricuspid annuloplasty in patients with tricuspid annular dilatation who undergo mitral valve repair could prevent progression of tricuspid regurgitation and right ventricular remodeling.[ncbi.nlm.nih.gov]
  • The presence of an akinetic patch in the right ventricular outflow tract (RVOT), a known factor promoting right ventricular dilatation, may prevent right ventricular recovery after valve implantation.[ncbi.nlm.nih.gov]

  • In some cases, this prevents the heart from filling with blood as it should. Over time, it can affect the other chambers. Symptoms Many people with dilated cardiomyopathy have no symptoms. Some that do have only minor ones, and live a normal life.[webmd.com]
