We report a case of a complicated vascular access secondary to systemic venous defects which have not been previously reported. Further evaluation revealed congenital absence of superior vena cava with two brachiocephalic veins draining separately. He also had absence of the hepatic segment of the inferior vena cava with azygos continuation. The patient did not have congenital anomalies of the remaining thoracoabdominal vasculature and viscera.

Transcatheter aortic valve implantation with preexisting mechanical mitral prosthesis - use of CT angiography.
A 72-year-old Chinese female with prior mitral valve replacement with a mechanical prosthesis 13 years before was diagnosed with severe symptomatic aortic stenosis. She was considered a high-risk surgical candidate and was considered for transcatheter aortic valve implantation using a balloon-expandable device. ⋯ Gated cardiac computed tomographic angiography was used to assess the distance between the mitral prosthesis and the aortic annulus. Transcatheter aortic valve implantation using the transapical approach was subsequently performed successfully.

The intra-aortic balloon pump (IABP) is a tool to help improve myocardial perfusion, reduce afterload, and decrease myocardial demand by reducing cardiac work. We describe a unique case of an IABP placement in a pregnant woman in her third trimester with a non-ST elevation myocardial infarction. The IABP allowed safe delivery of the fetus by cesarean section prior to a successful percutaneous intervention for complex two-vessel coronary artery disease. This case report also describes the first-time use of an IABP during cesarean section.
