Unusual echocardiographic finding leading to diagnosis of pulmonary sequestration [PDF]

, 2008
Pulmonary sequestration is an embryonic mass of non- functioning lung tissue that does not communicate with the tracheobronchial tree and has a reported incidence of 0.15%-6.4% of all the pulmonary malformations.

Bilateral coronary ostial stenosis and aortic regurgitation in a patient with cardiovascular syphilis [PDF]

, 2012
Cardiovascular syphilis is associated with the tertiary stage of syphilis infection; it involves the ascending aorta and can cause aortic aneurysm, aortic regurgitation, and coronary ostial stenosis. We report a surgical case of bilateral coronary ostial

Leucine‐Dependent SLC7A5–PGAM5 Interaction Promotes Advanced Atherosclerosis Through Hindering Mitochondrial Function of Macrophages

Advanced Science, EarlyView.
Higher plasma leucine is associated with increased risk of new‐onset myocardial infarction. Leucine deprivation alleviates advanced atherosclerosis in mice. Tumor‐induced leucine deprivation reprograms macrophage metabolism and increases CD5Lhi macrophages in mouse plaques. Mechanistically, leucine deficiency reduced SLC7A5‐PGAM5 binding in macrophages,

Computational fluid dynamicaccuracy in mimicking changes in blood hemodynamics in patients with acute type IIIb aortic dissection treated with TEVAR [PDF]

, 2018
Background: We aimed to verify the accuracy of the Computational Fluid Dynamics (CFD) algorithm for blood flow reconstruction for type IIIb aortic dissection (TBAD) before and after thoracic endovascular aortic repair (TEVAR).

Penetrating Ulcer of the Ascending Aorta

Journal of the American College of Cardiology, 2011
![Figure][1] A 77-year-old woman underwent coronary artery bypass grafting in 2002. The surgeon noted a mass on the ascending aorta, adjacent to the innominate artery. He performed an off-pump coronary artery bypass grafting procedure to avoid manipulation of the aorta.

Cortical Microvascular Pulsatility in the Aging Mouse Brain and the Confounding Effects of Anesthesia

Advanced Science, EarlyView.
Multi‐modal optical imaging reveals microvascular pulsatility in the brain cortex of awake and anaesthetized mice. Awake hemodynamics in male mice are found to be remarkably stable until late life, with flow pulsatility being significantly higher than in females, despite similar average perfusion.

Aortic pathology from protein kinase G activation is prevented by an antioxidant vitamin B12 analog. [PDF]

, 2019
People heterozygous for an activating mutation in protein kinase G1 (PRKG1, p.Arg177Gln) develop thoracic aortic aneurysms and dissections (TAAD) as young adults.
