With the increasing prevalence of chronic coronary syndromes, many patients with extensive atherosclerosis experience uncontrolled angina, even while receiving optimal medical therapy. This is especially true for patients who are not suitable candidates for surgical or percutaneous revascularization. Numerous treatments have been investigated for managing angina pectoris, and in this context, the coronary sinus reducer has emerged as a promising therapeutic option. Since the 1950s, beginning with Beck's surgery, the coronary venous sinus has been a focal point of research in anti-ischemic therapies. Significant scientific advances have been made in narrowing the venous sinus in the past two decades. Thanks to technological improvements in minimally invasive procedures and better methods for assessing myocardial blood flow, a new therapeutic option has become available for patients suffering from refractory angina and, possibly, for microvascular dysfunction. In this review, we aim to examine key concepts related to angina pectoris and myocardial ischemia, highlighting the historical background, pathophysiological rationale, and technical aspects of coronary sinus reduction as a therapy for refractory angina. Additionally, we will explore the scientific evidence from recent decades, as well as identify existing gaps and outline future research directions concerning this emerging treatment.

Percutaneous coronary intervention (PCI) is the most widely used coronary revascularization method worldwide, even in cases of high anatomical complexity. However, this increasing complexity has increased the risks associated with the procedure. Mechanical circulatory assist devices (MCADs), such as the iVAC 2L, have been used for hemodynamic support in high-risk PCIs. We describe the first case in Brazil of PCI performed with the support of the iVAC 2L, a pulsatile MCAD. The patient, an 81-year-old man, had functional class III angina and severe lesions in the left main coronary artery (LMCA), left anterior descending artery (LAD), and circumflex artery (CX), associated with extensive calcification. The procedure was performed with the support of the iVAC 2L, and PCI was performed with stenting of the LMCA, LAD, and CX. The entire procedure was performed without the need for vasoactive drugs, and the device was removed without vascular complications. High-risk PCI has become increasingly common, often requiring ventricular mechanical support. The iVAC 2L offers advantages such as pulsatile flow and ease of implantation, making it an alternative to the intra-aortic balloon pump and Impella. This report highlights the potential use of the iVAC 2L in Brazil, expanding therapeutic options for high-risk patients.
