Pulmonary Artery Intimal Sarcoma Mimicking Right Ventricular Outflow Tract Thrombus.

A 72-year-old man presented with breathlessness and a systolic murmur. Extensive diagnostic work-up revealed a rare pulmonary artery intimal sarcoma mimicking a right ventricular outflow tract thrombus and impacting a cardiac pacemaker lead. Surgical resection, pathology confirmation, and management strategies are discussed, highlighting the challenges of treating this rare malignancy.

Monckeberg calcification of coronary arteries: a string of pearls.

Coronary artery calcium scores are derived from cardiac-gated noncontrast computed tomography scans that are used in cardiac risk stratification. However, an elevated calcium score does not always translate to coronary artery luminal obstruction. Our case demonstrates an extremely high coronary artery calcium score despite nonobstructive coronaries on angiogram.

A pebble clogging a river: a case report of thrombosed coronary aneurysmal ectasia.

Background: Coronary artery ectasia (CAE) is a rare anomaly that can present at any age. Predisposing risk factors include Kawasaki disease in a younger population and atherosclerosis in the older generation. We present a unique case of the management of a young woman diagnosed with multivessel CAE with aneurysmal changes in the setting of acute coronary syndrome and subsequently during pregnancy.

Feasibility of exercise treadmill N-ammonia positron emission tomography myocardial perfusion imaging using an off-site cyclotron.

Background: Myocardial perfusion imaging with treadmill exercise nitrogen-13 (N)-ammonia positron emission tomography (PET) presents a logistical challenge. We investigated the feasibility of exercise treadmill (GXT) N-ammonia PET MPI using an off-site cyclotron for production of N-ammonia.

Methods: Thirty-three patients underwent GXT N-ammonia PET MPI over 23 months.

Giant Congenital Left Atrial Appendage Aneurysm Presenting With Recurrent Supraventricular Tachycardia and Chest Pain.

• LAAA is a rare anomaly characterized by appendage enlargement. • Clinical presentations of LAAA range from asymptomatic to life threatening. • Multimodality imaging, including TTE, is the mainstay of diagnosis.

Characterization of 3-Dimensional PET Systems for Accurate Quantification of Myocardial Blood Flow.

Unlabelled: Three-dimensional (3D) mode imaging is the current standard for PET/CT systems. Dynamic imaging for quantification of myocardial blood flow with short-lived tracers, such as Rb-chloride, requires accuracy to be maintained over a wide range of isotope activities and scanner counting rates. We proposed new performance standard measurements to characterize the dynamic range of PET systems for accurate quantitative imaging.

Expert consensus for multi-modality imaging evaluation of cardiovascular complications of radiotherapy in adults: a report from the European Association of Cardiovascular Imaging and the American Society of Echocardiography.

Cardiac toxicity is one of the most concerning side effects of anti-cancer therapy. The gain in life expectancy obtained with anti-cancer therapy can be compromised by increased morbidity and mortality associated with its cardiac complications. While radiosensitivity of the heart was initially recognized only in the early 1970s, the heart is regarded in the current era as one of the most critical dose-limiting organs in radiotherapy.
