293 Anomalies of coronary artery ostia in common arterial trunk [PDF]

, 2011
BackgroundTbx1 controls outflow tract development and coronary artery patterning, with subaortic coronary-permissive and subpulmonary coronary-refractory myocardial domains. Our hypothesis is that the potential “pulmonary identity” of the common arterial

Syphilitic aortitis causing critical obstruction of coronary ostia [PDF]

European Heart Journal, 2008
A 32-year-old man presented to the hospital soon after the onset of chest pain. Physical examination revealed blood pressure 95/60 mmHg, heart rate 94 b.p.m., and rales on both pulmonary bases. Electrocardiogram showed ST-segment depression, especially in V1–V5, up to 5 mm in V3. After medication, the …

Chimney grafts in renal arteries: a clinical model for coronary perfusion in future transcatheter aortic root repair techniques

Journal of Cardiothoracic Surgery, 2020
Objectives Given the similarities between coronary ostia and renal arteries, chimney grafts (CG) for kidney perfusion during abdominal endovascular aneurysm repair (EVAR) can be considered for coronary perfusion in future transcatheter aortic root repair

Surgical removal of an exceedingly rare papillary fibroelastoma of the aortic wall causing unstable angina

Clinical Case Reports, 2021
Difficult diagnosis is due to rarity of the case. TT or TE echocardiography is sufficient to make a correct diagnosis. The risk of embolism or coronary ostia occlusion should guide the decision for surgery.
