Subclavian artery stenosis (SAS) resulting in coronary subclavian steal syndrome (CSSS) is a common but under recognized pathology following coronary artery bypass surgery (CABG). Patients with SAS may be asymptomatic due to the sub-clinical diversion of blood flow from the myocardium and retrograde blood flow during catheter angiography in the left internal mammary artery (LIMA) may be the first suggestion of CSSS. The management of SAS, causing CSSS, may rarely require acute assessment and intervention. However, full anatomical assessment of the stenosis morphology may be limited on fluoroscopy. Correction of SAS may be essential to achieve effective reperfusion therapy.

The unique structure and location of the internal thoracic artery make it an ideal conduit for coronary artery bypass grafting surgery and autologous breast reconstruction. Variants with different characteristics have the potential to impact surgical success. This report presents a female body donor with a novel bilateral variation of the internal thoracic artery.

The intra-aortic balloon pump (IABP) is a widely-used mechanical circulatory support device that enhances hemodynamics in patients with heart conditions. Although the IABP is a common clinical tool, its effectiveness in enhancing outcomes for patients with acute myocardial infarction and cardiogenic shock remains disputed. This study aimed to assess the effectiveness of intra-aortic dual-balloon pump (IADBP) and its impact on aortic hemodynamics compared with an IABP.

The optimal management of acute type A aortic dissection (ATAAD) remains a controversial subject. While some surgeons opt for a hemiarch approach to minimize bypass and cross-clamping time, others prefer partial or total arch replacement to prevent the need for additional operations. The advent of hybrid approaches offers a variety of options to the aortic surgeon in treating ATAAD.

TAAs involving the proximal arch require adequate coverage with thoracic endovascular aortic repair, which is timely and challenging in emergent ruptures. In situ laser fenestration is a novel method of arch revascularization.

Background: The sympathetic autonomic nervous system plays a major role in arrhythmia development and maintenance. Historical preclinical studies describe preferential increases in cardiac sympathetic tone upon selective stimulation of the subclavian ansae (SA), a nerve cord encircling the subclavian artery.
Objectives: This study sought to define, for the first time, the functional anatomy and physiology of the SA in humans using a percutaneous approach.
