Severe tortuosity of the right subclavian artery (RSCA) encountered during transradial cardiac catheterization can lead to longer procedures, increased fluoroscopy time, inability to engage the coronary artery ostia, and potentially procedural failure. Increasing age is strongly correlated with subclavian tortuosity; however, the magnitude and direction of age-related changes in aortic ...

One drawback of the arterial switch operation for treating transposition of the great arteries is the occurrence of coronary lesions, found during follow-up in about 5% of (a)symptomatic children. The established corrective procedures include coronary artery proximal patch arterioplasty or coronary artery bypass grafting (CABG). To avoid aortic manipulations and ...

Moyamoya disease (MMD) is a rare disease characterized by occlusive intracranial arteriopathy with formation of abnormal cerebrovascular collateral networks. Conventional cardiovascular surgical procedures using cardiopulmonary bypass for patients with MMD is challenging because low cerebral perfusion pressure and nonpulsatile (continuous) flow during cardiopulmonary bypass can cause severe cerebral ischemia. We ...
