Distended Neck Veins
  • Clinical circumstances that are associated with acute right heart syndromes, such as known ARDS, sickle cell crisis, pre-existing pulmonary hypertension; chronic lung disease; or following cardiac surgery Physical examination may reveal distended neck[clinicaladvisor.com]
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]

Workup

Ejection Fraction Decreased
  • It also showed the dilatation and functional impairment of the left ventricle (end diastolic diameter: 60mm, end diastolic volume: 243ml and ejection fraction decreased by 40%).[escardio.org]
Poor R Wave Progression
  • Figure 3 shows atrial fibrillation, poor R wave progression, and diffuse ST-segment abnormalities in an ECG from a patient with ischemic cardiomyopathy.[clevelandclinicmeded.com]
Left Atrial Hypertrophy
  • atrial hypertrophy, dilatation, or hypertension, since the last three cannot be differentiated by the ECG.[academic.oup.com]

Treatment

  • A triad of circulatory collapse, right ventricular dilatation, and large alveolar dead space is proposed for the rapid diagnosis and treatment of massive pulmonary embolism.[ncbi.nlm.nih.gov]
  • Standard treatment of right ventricular outflow tract or pulmonary artery obstruction involves open chest surgery.[nice.org.uk]
  • The completely revamped interventional section includes new material on treatment of pediatric and adult congenital heart disease, as well as on coronary atherectomy, thrombectomy, distal embolic protection devices, bare metal and drug-eluting stents,[books.google.de]

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]
  • The prognosis of pulmonary hypertension (PH) depends upon the functional capacity of the right ventricle.[jscimedcentral.com]
  • Our outcome figures suggest a guarded prognosis be given during counseling of parents of fetuses with right heart dilatation.[link.springer.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]
  • […] hypoplastic left heart syndrome interrupted aortic arch aortic coarctation ventricular septal defect 1 congenital pulmonary stenosis : tends to cause more wall hypertrophy rather than chamber dilatation dilated fetal cardiomyopathy more unusual cardiac etiologies[radiopaedia.org]
  • 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]
  • A systematic approach to define the etiology is essential for determination of the most effective treatment strategy.[emedicine.medscape.com]
  • Other studies should be individualized depending upon the suspected etiology of RHF.[revespcardiol.org]

Epidemiology

  • Overview of major types of cardiomyopathy Dilated cardiomyopathy Epidemiology Most common cardiomyopathy Incidence : 6/100,000 per year Sex: (approx. 3:1) Etiology Idiopathic (approx. 50%) Secondary cause Coronary heart disease Arterial hypertension Peripartum[amboss.com]

[13, 14] Treatment with cyclosporine and corticosteroids is associated with a median transplant-free survival of 12.3 months compared to 3 months without immunosuppression.

Prevention

  • 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]
  • 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.[hartlongcentrum.nl]
