Lack of diagnostic utility of the ECG-derived ventricular gradient in patients with suspected acute pulmonary embolism.

J Electrocardiol 2020 Jun 5;61:141-146. Epub 2020 Jun 5.

Department of Thrombosis and Hemostasis, Leiden University Medical Center, Leiden, the Netherlands.

Introduction: The YEARS algorithm was successfully developed to reduce the number of computed tomography pulmonary angiography (CTPA) investigations in the diagnostic management of patients with suspected pulmonary embolism (PE), although half of patients still needed to be referred for CTPA. We hypothesized that ECG derived ventricular gradient optimized for right ventricular pressure overload (VG-RVPO), an easy to use tool for detecting PE-induced pulmonary hypertension (PH), may further improve the efficiency of the YEARS algorithm.

Methods: In this post-hoc analysis of the Years study, ECGs of 479 patients with suspected PE managed according to the YEARS algorithm were available for analysis. Read More

From CT to artificial intelligence for complex assessment of plaque-associated risk.

Int J Cardiovasc Imaging 2020 Jul 2. Epub 2020 Jul 2.

Department of Internal Medicine of the University of Medicine, Pharmacy, Sciences and Technology "George Emil Palade", Gheorghe Marinescu Street, no. 38, 540139, Târgu Mureș, Mureș County, Romania.

The recent technological developments in the field of cardiac imaging have established coronary computed tomography angiography (CCTA) as a first-line diagnostic tool in patients with suspected coronary artery disease (CAD). CCTA offers robust information on the overall coronary circulation and luminal stenosis, also providing the ability to assess the composition, morphology, and vulnerability of atherosclerotic plaques. In addition, the perivascular adipose tissue (PVAT) has recently emerged as a marker of increased cardiovascular risk. Read More

Eur Heart J Case Rep 2020 Jun 3;4(3):1-5. Epub 2020 May 3.

University of Maryland School of Medicine, Baltimore, MD, USA.

Background: Coronary artery aneurysms (CAA) are often diagnosed incidentally on coronary angiography or imaging modalities done for other reasons. 'Giant' CAA by definition exceeds 20 mm in diameter or four times the diameter of normal coronary artery. The management of patients with CAAs is challenging due to poorly understood mechanism, variable presentation, and lack of clear-cut societal recommendations. Read More

Cardioembolic stroke in a young male with cor triatriatum sinister: a case report.

Eur Heart J Case Rep 2020 Jun 3;4(3):1-6. Epub 2020 May 3.

Department of Cardiology, University of Maryland Medical Center, 22 South Greene Street, Baltimore, MD 21201, USA.

Background: Cor triatriatum sinister (CTS) is a rare congenital cardiac anomaly defined by a fibromuscular membrane which bisects the left atrium. Cor triatriatum sinister has been associated with cardioembolic stroke through mechanisms including stagnation of blood flow within the left atrium, an association with atrial fibrillation (AF), and/or an accompanying atrial septal defect (ASD) or patent foramen ovale. We describe a case highlighting the role that CTS may play in cardioembolic stroke, provide high-quality computed tomography angiography and two- and three-dimensional echocardiography of the CTS membrane, and outline management strategies for this uncommon clinical scenario.
