Comparison of the Diagnostic Performance of Myocardial Perfusion Scintigraphy with and Without Attenuation Correction.

Mol Imaging Radionucl Ther 2022 Jun;31(2):130-138

Chulalongkorn University and King Chulalongkorn Memorial Hospital, Department of Radiology, Division of Nuclear Medicine, Bangkok, Thailand.

Objectives: Myocardial perfusion scintigraphy (MPS) is an important diagnostic test for detecting of coronary artery stenosis (CAS); however, tissue attenuation can lead to a difference in accuracy. We evaluated the diagnostic accuracy of attenuation-corrected (AC) and non-attenuation-corrected (NC) MPS for the detection of CAS.

Methods: We retrospectively recruited patients who underwent invasive coronary angiography within 10 months after Tc-99m sestamibi MPS. Read More

Practical Workflow for Cardiovascular Assessment and Follow-Up in Kawasaki Disease Based on Expert Opinion.

Front Pediatr 2022 9;10:873421. Epub 2022 Jun 9.

Department of Pediatric Cardiology, Emma Children's Hospital, Amsterdam University Medical Center (UMC), University of Amsterdam, Amsterdam, Netherlands.

Background: Approximately 25% of the patients with a history of Kawasaki disease (KD) develop coronary artery pathology if left untreated, with coronary artery aneurysms (CAA) as an early hallmark. Depending on the severity of CAAs, these patients are at risk of myocardial ischemia, infarction and sudden death. In order to reduce cardiac complications it is crucial to accurately identify patients with coronary artery pathology by an integrated cardiovascular program, tailored to the severity of the existing coronary artery pathology.

Free-running cardiac and respiratory motion-resolved 5D whole-heart coronary cardiovascular magnetic resonance angiography in pediatric cardiac patients using ferumoxytol.

J Cardiovasc Magn Reson 2022 Jun 27;24(1):39. Epub 2022 Jun 27.

Department of Diagnostic and Interventional Radiology, Lausanne University Hospital (CHUV) and University of Lausanne (UNIL), Rue de Bugnon 46, BH-8-84, 1011, Lausanne, Switzerland.

Background: Coronary cardiovascular magnetic resonance angiography (CCMRA) of congenital heart disease (CHD) in pediatric patients requires accurate planning, adequate sequence parameter adjustments, lengthy scanning sessions, and significant involvement from highly trained personnel. Anesthesia and intubation are commonplace to minimize movements and control respiration in younger subjects. To address the above concerns and provide a single-click imaging solution, we applied our free-running framework for fully self-gated (SG) free-breathing 5D whole-heart CCMRA to CHD patients after ferumoxytol injection.

Mitral annular calcification: The incremental diagnostic value of 3D transesophageal echocardiography.

Echocardiography 2022 Jun 24. Epub 2022 Jun 24.

Medical College of Georgia, Augusta University, Augusta, Georgia, USA.

Three-dimensional (3D) echocardiography is an important tool in the evaluation of mitral valve anatomy. We illustrate a case of a 67-year-old female who was admitted for non-ST-elevation myocardial infarction (NSTEMI) and underwent two-vessel coronary artery bypass grafting for surgical disease. Her two-dimensional (2D) echocardiographic images intraoperatively demonstrated a mass on the posterior mitral valve leaflet which created a diagnostic challenge; 3D transesophageal imaging was crucial in identifying the true nature of the pathology to be mitral annular calcification with supra-annular extension.

Unit of Medical Technology and Intelligent Information Systems, Department of Materials Science and Engineering, University of Ioannina, GR 45110 Ioannina, Greece.

The prediction of obstructive atherosclerotic disease has significant clinical meaning for the decision making. In this study, a machine learning predictive model based on gradient boosting classifier is presented, aiming to identify the patients of high CAD risk and those of low CAD risk. The machine learning methodology includes five steps: the preprocessing of the input data, the class imbalance handling applying the Easy Ensemble algorithm, the recursive feature elimination technique implementation, the implementation of gradient boosting classifier, and finally the model evaluation, while the fine tuning of the presented model was implemented through a randomized search optimization of the model's hyper-parameters over an internal 3-fold cross-validation.

Biomedicines 2022 Jun 2;10(6). Epub 2022 Jun 2.

Centro Cardiologico Monzino IRCCS, 20138 Milan, Italy.

Existing tools to estimate cardiovascular (CV) risk have sub-optimal predictive capacities. In this setting, non-invasive imaging techniques and omics biomarkers could improve risk-prediction models for CV events. This study aimed to identify gene expression patterns in whole blood that could differentiate patients with severe coronary atherosclerosis from subjects with a complete absence of detectable coronary artery disease and to assess associations of gene expression patterns with plaque features in coronary CT angiography (CCTA).

Prenatal diagnosis of a coronary-to-pulmonary artery fistula in a fetus with pulmonary atresia and ventricular septal defect.

BMJ Case Rep 2022 Jun 22;15(6). Epub 2022 Jun 22.

Department of Pediatrics, School of Medicine Graduate School of Medicine, Osaka University, Suita, Osaka, Japan.

Pulmonary atresia and ventricular septal defect (PA/VSD) demonstrate a wide variety of pulmonary and coronary artery abnormalities; additionally, coronary-to-pulmonary artery fistula (CPAF) is a rare manifestation of PA/VSD and is seldom detected during pregnancy. In this report, we present a case of prenatal diagnosis of CPAF in PA/VSD and impactful images in a neonate, which were obtained using fetal echocardiography and postnatal electrocardiography-gated 320-row CT. Prenatal diagnosis of CPAF can facilitate the provision of better therapeutic strategies after birth. Read More

High-Risk Coronary Plaque Features: A Narrative Review.

Cardiol Ther 2022 Jun 22. Epub 2022 Jun 22.

Department of Medicine, Monash University, Clayton campus, Melbourne, VIC, Australia.

Advances in coronary plaque imaging over the last few decades have led to an increased interest in the identification of novel high-risk plaque features that are associated with cardiovascular events. Existing practices focus on risk stratification and lipid monitoring for primary and secondary prevention of cardiac events, which is limited by a lack of assessment and treatment of vulnerable plaque. In this review, we summarize the multitude of studies that have identified plaque, haemodynamic and patient factors associated with risk of acute coronary syndrome. Read More

Circ Cardiovasc Imaging 2022 Jun 21;15(6):e012741. Epub 2022 Jun 21.

Department of Medicine (Division of Artificial Intelligence), Imaging, and Biomedical Sciences, Cedars-Sinai Medical Center, Los Angeles (B.K.T., Y.O., L.-H.H., H.G., E.E., J.X.L., D.D., D.S.B., P.J.S.).

Background: Semiquantitative assessment of stress myocardial perfusion defect has been shown to have greater prognostic value for prediction of major adverse cardiac events (MACE) in women compared with men in single-center studies with conventional single-photon emission computed tomography (SPECT) cameras.
