ConclusionsThe prevalence of EI-LBBB among the patients that came to undergo GATED-SPECT ergometry was very low. The finding was more frequent in women. In our series, 2 patients presented non-ischemic structural heart disease, but no patient was diagnosed with coronary artery disease. In our patients the presence of EI-LBBB did not relate to a greater risk of experiencing a major cardiovascular event.ResumenIntroducciónEl bloqueo completo de rama izquierda inducido por el ejercicio (BCRI-IE) es un fenómeno poco frecuente y de significado incierto.

Written by Pendell Meyers, with edits by Steve SmithA male in his early 40s presented with intermittent chest/abdominal pain. He admitted to several episodes over the past two days, including one episode several hours prior to presentation, described as severe (8/10), substernal " burning, " non-radiating, associated with diaphoresis, described as " feeling food stuck in my throat, " or " like I ate too fast, " but not associated with eating, relieved by belching and flatulence, relieved by lying flat. The episode on the day of presentation was similar except he had the additional new features...

We report a case of moyamoya disease (MMD), which developed after non-herpetic acute limbic encephalitis (NHALE) associated with anti-leucine-rich glioma-inactivated 1 (LGI1) antibody. The patient’s mother had a history of MMD. No vascular lesions were identified at the time of the NHALE. Nine years later, the patient visited our hospital due to memory disturbances and repeated transient ischemic attacks affecting the right limb. Diffusion-weighted magnetic resonance imaging revealed scattered areas of signal hyperintensity, and the patient was ultimately diagnosed with MMD based on angiography. Revascularization sur...

AbstractAim and PatientsThe aim of the present study was to assess the additional value of systolic wall thickening to myocardial perfusion in diagnosing myocardial stunning induced by dipyridamole infusion. We selected 52 ischemic patients (43 males; mean age 65.5  ± 7.64), with CAD documented by angiography. Ischemia was defined as a summed difference score ≥ 5. All patients underwent a 2-day gated perfusion SPECT protocol. The patients received a dose of 740 MBq of 99mTc-tetrofosmin after stress and at rest.ResultsThe post-stress LVEF was significantly lower than rest LVEF (48.3%  &plu...

We examined this relationship in a large population of patients in whom the coronary anatomy was defined by invasive coronary angiography. Methods We retrospectively extracted details on individuals undergoing MPI with single photon emission computed tomography (SPECT) who had coronary angiography within 12 months. A 17-segment model for native coronary anatomy and a 7-region model for myocardial perfusion were used with a dedicated matching algorithm. Results A total of 2564 patients were included, yielding a total of 6279 stenoses matched with 17 948 myocardial regions. From such a cohort, 151 (5.9%) patients had...

ConclusionThe REFINE SPECT registry will provide a resource for collaborative projects related to the latest generation SPECT-MPI. It will aid in the development of new artificial intelligence tools for automated diagnosis and prediction of prognostic outcomes.

Conclusion In this case series, a large proportion of patients with isolated SSPE on V/Q imaging were not identified on corroborating CTPA performed within 48 h. In patients with isolated SSPE (identified by isolated subsegmental mismatch on V/Q single-photon emission computed tomography), we found no difference in risk of recurrent suspected VTE or all-cause mortality in those treated with anticoagulation and those not treated.
