Atrial arrhythmias and scintigraphic “D-shape” sign in pulmonary artery hypertension

Abstract: Pulmonary hypertension significantly changes biventricular anatomy and physiology, frequently evolving to clinical deterioration and right ventricular failure. The case of a woman developing atrial arrhythmias complicating dipyridamole stress in concomitance with scintigraphic “D-shaped” left ventricle is briefly reported. Although rare, our finding may suggest that nonselective vasodilators should be used with caution in this clinical setting.

“…Consistent with previous studies of patients with acute PE in whom RV dysfunction was documented, there is a subjective component to this interpretation, particularly when echocardiography is the imaging modality utilized. In addition, while a measured RV/LV ratio > 0.9 in the apical 4 chamber view on either CTA or echocardiography suggests RV dilation, volume status, and chronic medical conditions such as obesity, pulmonary hypertension, and right-sided valvular insufficiency all augment RV loading conditions may be interpreted as evidence of "RV dysfunction" [20,[32][33][34]. These factors require external validation.…”

Therefore, any cause of increased contrast noted in the pulmonary vasculature and RV by CTA is subject to being interpreted as evidence on "RV dysfunction", as reported 20,[32][33][34] . Our study also excluded patients with a pre-existing diagnosis of VTE/PE, or patients with diagnosis of acute PE at an outside facility who were later transferred in to our institution.…”

“…Transthoracic echocardiography (TTE) in a patient with advanced PAH is conspicuous by the RV cavity′s abnormal shape, especially in the parasternal short axis ( Figure 5 ). The RV assumes a spherical shape, and the interventricular septum protrudes into the LV, forming the so-called D-shape sign [ 18 ]. If a D-shaped LV appears in the end-diastolic phase, it suggests RV pressure overload, whereas a D-sign shape in diastole suggests RV volume overload [ 19 , 20 ].…”
