Scintigraphic and radiographic correlation of a non-sestamibi-avid lung mass invading the left ventricle serendipitously discovered during adenosine myocardial perfusion imaging is presented. The only clue to the presence of the mass was deformation of the anterior wall on SPECT myocardial perfusion imaging. This case serves as a reminder that although the appearance of pathology on a nuclear medicine imaging study is typically what is seen (specifically, increased radiopharmaceutical uptake), it can just as importantly be what is not seen.

Anomalous Aortic Origin of a Coronary Artery in Pediatric Patients.
Curr Pediatr Rep
May 2024
Coronary Artery Anomalies Program, Division of Cardiology, Texas Children's Hospital, 6651 Main Street MC-E1920, Houston, TX 77030 USA.
Purpose Of Review: We present a contemporary approach to risk assessment and management of patients with anomalous aortic origin of a coronary artery (AAOCA).
Recent Findings: Anomalous left coronary artery from the right aortic sinus (L-AAOCA) with interarterial course carries a high risk of sudden cardiac death (SCD); therefore, current guidelines recommend exercise restriction and surgical intervention. Recent data in intraseptal and juxtacommissural L-AAOCA showed inducible perfusion abnormalities, leading to consideration of surgical intervention.
A comparison between 64-projection and 32-projection myocardial perfusion scintigraphy.
Eur Heart J Imaging Methods Pract

Student Research Committee, Shiraz University of Medical Sciences, Shiraz, Iran.
Aims: While most clinical guidelines recommend using a 64-projection view technique, some protocols do not specify a preference between 32-projection and 64-projection methods for conducting myocardial perfusion scintigraphy (MPS), which shows the lack of consensus in this matter. Nevertheless, these guidelines and protocols have not provided us with compelling evidence to support why the 64-projection technique is usually chosen. Thus, we aimed to determine if there is a significant difference between them in the assessment of cardiac perfusion and functional indices.

Curr Cardiol Rep
January 2025
Onassis Cardiac Surgery Center, Athens, Greece.
Purpose Of Review: Our purpose was to discuss the advantages and disadvantages of various noninvasive imaging modalities in the evaluation of cardiovascular disease (CVD) in patients with autoimmune rheumatic diseases (ARDs). The detailed knowledge of imaging modalities will facilitate the diagnosis and follow up of CVD in ARDs.
Recent Findings: Autoimmune Rheumatic Diseases (ARDs) are characterized by alterations in immunoregulatory system of the body.
Focusing on microvascular function in heart failure with preserved ejection fraction.
Heart Fail Rev

Department of Cardiology, Cardiology I, University Medical Center Mainz, Langenbeckstrasse 1, 55131, Mainz, Germany.
Heart failure is a prevalent global health issue. Heart failure with preserved ejection fraction (HFpEF), which already represents half of all heart cases worldwide, is projected to further increase, driven by aging populations and rising cardiovascular risk factors. Effective therapies for HFpEF remain limited, particularly due to its pathophysiological heterogeneity and incomplete understanding of underlying pathomechanisms and implications.

Septic patients are routinely exposed to endogenously released and exogenously administered catecholamines, which may alter cardiac function and perfusion causing ischemia. Early during human septic shock, left ventricular ejection fraction (LVEF) decreases but normalizes in survivors over 7-10 days.
