Masked Ischemia on Myocardial Perfusion Imaging: A Case Example

Arash Gholoobi

Case Presentation: A 67-year-old man underwent exercise electrocardiography (ECG)-gated single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) for evaluating his mild dyspnea on exertion (New York Heart Association class I). Images showed inducible ischemia of severe intensity in the interior walls and moderate intensity in the apicoseptal and anteroseptal segments, but exercise stress to induce coronary hyperemia revealed marked ST-segment depressions in low heart rates and the patient complained of only mild dyspnea during these ECG changes. He subsequently underwent coronary angiography, which revealed left main and severe three-vessel disease. This discrepancy between the SPECT perfusion images and the extent of coronary artery disease in this case represents the masking of one ischemic territory (left system) by another more severely ischemic territory (right system).

Discussion: The reason is that we assess the relative and not absolute differences of the tracer uptake in this imaging modality. There may be other findings on MPI images which could help us overcome this pitfall, including detecting wall motion abnormalities, lung uptake of the tracer, or transient ischemic dilation. Another important issue is the ECG changes during exercise stress testing, which could point to a more extensive coronary artery disease than the one detected on MPI images alone.

Libman-Sacks Endocarditis and Cerebral Infarction in Antiphospholipid Syndrome: A Case Report

Farahnaz Nikdoust, Mansoureh Eghbalnezhad

Valvular heart disease is a considerable finding in the antiphospholipid antibody syndrome (APS). The involvement of the mitral and aortic valves is more common in the form of leaflet thickening or aseptic verrucous vegetations called the Libman-Sacks endocarditis. In addition to the detrimental effects of endocarditis on the valves, it can lead to serious thromboembolic complications. Here we report our experience with a young woman, who had a history of transient ischemic attack 2 months earlier and referred to us due to severe vaginal bleeding. On echocardiography, several irregular masses were observed on the atrial side of both mitral valve leaflets. On rheumatologic work-up, she was found to have positive anticardiolipin IgG and lupus anticoagulant. During hospitalization, the patient suffered thrombotic stroke and computed tomography (CT) scan showed a parietal lobe ischemic lesion. With evidence of positive antiphospholipid antibodies and arterial thrombosis, negative blood culture, and no fever, the diagnosis of the Libman-Sacks endocarditis was established. The patient was discharged with good general condition and received Hydroxychloroquine, Warfarin, and Prednisolone. On follow-up echocardiography, intra-cardiac masses were not detected any more and no residual neurologic deficits were found.

Echocardiographic Evaluation of Orthotopic Heart Transplantation: Single-Center Experience

Results: Eleven males and five females at a mean age of 33 years [range = 17-58 years] were enrolled in the study. The mean of the left ventricular ejection fraction (LVEF) was 52 ± 8.2 % and 58 ± 2.5 % on the first day and at 5 months after HTx, respectively. There was no LV enlargement at 5 months' follow-up. The right ventricle (RV) was mildly enlarged, but the reduced baseline RV function showed improvement at the 5th postoperative month (mean TAPSE was 11.7 ± 3.3 mm on the first post-HTx day versus 17.2 ± 6.3 mm after 5 months; P < 0.005). The pulmonary arterial pressure was slightly elevated at baseline, and it showed no significant decrease 5 months after HTx. More than 90% of the cases showed only mild tricuspid regurgitation at 5 months' follow-up. The tissue Doppler imaging-derived velocities of the medial and lateral mitral annuli and the tricuspid annulus demonstrated a gradual increment during the follow-up and reached their highest value at 5 months' follow-up.
