195 Possible Causes for Right Atrial Pressure Elevated

  • Idiopathic and/or Familial Pulmonary Arterial Hypertension

    Right atrial pressure (RAP) is often assumed to be low, but patients with PAH often have elevated RAP.[] Right atrial size assessment from the apical four-chamber view can also be an important marker for response to therapy and outcomes in PAH.[] Long-axis interrogation of the IVC from subcostal imaging, 1–2 cm from the RA junction, can predict elevated RA pressures 10 mm Hg in PAH patients with 89% sensitivity and[]

  • Cyanosis

    It is critical to realize that right-to-left shunting at the atrial level is a function of RV filling pressure, and not always secondary to elevated right heart systolic pressure[] Conclusion Elevated right atrial pressure secondary to RV non-compliance and severe pulmonary regurgitation may progress to right-to-left atrial shunting if a PFO is present[] right atrial pressures secondary to RV noncompliance, tricuspid regurgitation and PV regurgitation.[]

  • Liver Fibrosis

    Postoperative right atrial pressures were consistently elevated above 13 mm Hg and this, in part, may have been due to progressive mild conduit stenosis.[] A 15-year-old girl was found to have severe liver fibrosis on liver biopsy at the time of cholecystectomy, 5 1/2 years following a modified Fontan procedure (right atrial-right[]

  • Aphthous Stomatitis

    Hemodynamic study showed a slightly elevated right atrial pressure (mean 7 mmHg) and a peak-to-peak intraventricular pressure difference of 18 mmHg in the right ventricle.[] Angiographic study revealed a markedly enlarged right atrium and a filling defect at the mid-portion of the right ventricle, which divided the right ventricular cavity into[]

  • Endocardial Fibroelastosis

    Hemodynamic and angiographic studies revealed marked elevation of right and left ventricular end-diastolic pressures with dip and plateau pressure contours, moderate pulmonary[] Further elevation of right and left ventricular diastolic pressures and pulmonary artery pressure was observed at the second evaluation after 5 years.[] […] hypertension, left atrial enlargement and mild mitral regurgitation.[]

  • Azithromycin

    Liver injury associated with right heart failure was unlikely, as right ventricular function was relatively preserved and right atrial pressure was not severely elevated.[]

  • Ischemia

    Elevated right atrial pressure is found only in the typical syndrome of elevated venous pressure; low output syndrome can be found only in 20% of the cases, and cardiogenic[] […] shock secondary to right ventricular necrosis is found only in 10%.[] The majority of patients with right ventricular infarction only exhibit subtle signs of ischemic dysfunction.[]

  • Idiopathic Pulmonary Fibrosis

    As right ventricular hypertrophy ensues, a right ventricular heave may be palpated at the lower left sternal border and increased right atrial pressure may cause elevation[]

  • Endocardial Cushion Defect

    The six patients with an endocardial cushion defect had elevated right atrial mean pressure and evidence of right atrial volume overload.[] Ultrastructurally, the atrial muscle cells in these patients appeared normal and measured 6 to 12 mu in diameter.[]

  • Idiopathic Hypereosinophilic Syndrome

    right atrial pressure relative to right ventricular pressure.[] […] hemodynamics secondary to severe tricuspid stenosis were demonstrated by CW Doppler with intermittent "signal fusion" resulting from blunted respiratory variation in the markedly elevated[]
