21. Sometimes, in the presence of ventricular disease associated with dilatation , EDV may vary. 22. Symptomatic Schatzki rings may be treated with esophageal dilatation , using bougie or balloon dilators. 23. Dal-VESSEL phase IIb trial found no evidence of flow-mediated dilatation improvement. 24. Chronic pulmonary heart disease usually results in right ventricular hypertrophy ( RVH ), whereas dilatation . 25. This structure theory is compatible with the action of the pseudo-orthogonal groups plus dilatations . 26. All five embryonic dilatations of the primitive heart develop into the adult structures of the heart. 27. Dilatation is a stretching ( in length ) of the ventricle in response to acute increased pressure.28. Finally, in an attempt to offset decreased blood pressure, ventricular dilatation and myocardial dysfunction occur. 29. A more thorough histologic evaluation can be obtained by a dilatation and curettage, which requires anesthesia. 30. Proximal celiac artery stenosis with poststenotic dilatation can be seen in other conditions affecting the celiac artery.
