RESUMEN
The Society for Cardiovascular Angiography and Interventions (SCAI) Think Tank is a collaborative venture that brings together interventional cardiologists, administrative partners, and select members of the cardiovascular industry community annually for high-level field-wide discussions. The 2021 Think Tank was organized into four parallel sessions reflective of the field of interventional cardiology: (a) coronary intervention, (b) endovascular medicine, (c) structural heart disease, and (d) congenital heart disease. Each session was moderated by a senior content expert and co-moderated by a member of SCAI's Emerging Leader Mentorship program. This document presents the proceedings to the wider cardiovascular community in order to enhance participation in this discussion, create additional dialog from a broader base, and thereby aid SCAI, the industry community and external stakeholders in developing specific action items to move these areas forward.

Formally described by Prinzmetal and colleagues in 1959, variant angina represents a syndrome of resting angina that results from severe coronary artery vasospasm associated with ST elevation. The majority of patients respond to nitrates or calcium channel blockers. However, medical treatment-resistant vasospasm can occur in up to 20% of cases, thus requiring further interventions. We present a rare instance of coronary vasospasm associated with complete heart block resistant to medical therapy that was successfully treated with stenting. This case example is followed by a detailed review of the literature with regard to percutaneous or surgical coronary revascularization of patients with medically resistant vasospasm.

A case of infectious endocarditis with septic embolization as a rare but potentially fatal complication of cardiac catheterization is described, followed by a detailed review of the literature. Obesity, diabetes, many skin punctures, previous bypass surgery and abnormal valves are predisposing factors for bacteremia following cardiac catheterization.
RESUMEN
OBJECTIVE: Common femoral endarterectomy (CFE) remains the standard of care for treatment of atherosclerotic stenosis of the common femoral artery (CFA). Endovascular interventions have become the first-line therapy for atherosclerotic disease of the aortoiliac and femoropopliteal systems. Recent reports have documented high rates of technical success and low rates of complications with endovascular management of CFA stenosis. This study is a contemporary review of the surgical and endovascular literature on the management CFA stenosis and compares the results of these methods. METHODS: A search of OVID Medline identified all published reports of revascularization of isolated atherosclerotic CFA stenosis. For each study selected for review, the number of patients, number of limbs treated, percentage of patients with critical limb ischemia, and mean length of follow-up was recorded. Study end points included survival, primary patency, freedom from target lesion revascularization (TLR), freedom from amputation, and complications. RESULTS: The review included 7 CFE studies and 4 endovascular studies. Survival was similar between the groups. Primary patency was consistently higher with CFE compared to endovascular therapy. Freedom from TLR was lower with CFE compared to endovascular therapy. Morbidity and mortality was also higher with CFE compared to endovascular therapy. Freedom from amputation was not consistently reported in the endovascular studies. CONCLUSION: There is limited data to support endovascular treatment of isolated CFA atherosclerosis. CFE has durable results, but there is significant morbidity and mortality resulting from this procedure. Endovascular interventions have low rates of complications, high rates of technical success, good short-term patency but increased need for repeat interventions when compared to surgery. Further trial data comparing CFE with endovascular therapy is needed to guide the management of CFA stenosis.

The clinical benefits of using the left internal mammary artery (LIMA) to bypass the left anterior descending artery are well established making it the most frequently used conduit for coronary artery bypass surgery (CABG). Coronary subclavian steal syndrome (CSSS) occurs during left arm exertion when (1) the LIMA is used during bypass surgery and (2) there is a high grade (≥75%) left subclavian artery stenosis or occlusion proximal to the ostia of the LIMA resulting in "stealing" of the myocardial blood supply via retrograde flow up the LIMA graft to maintain left upper extremity perfusion. Although CSSS was once thought to be a rare phenomenon, its prevalence has been underestimated and is becoming increasingly recognized as a serious threat to the success of CABG. Current guidelines are lacking on recommendations for screening of subclavian artery stenosis (SAS) pre- and post-CABG. We hope to provide an algorithm for SAS screening to prevent CSSS in internal mammary artery bypass recipients and review treatment options in the percutaneous era.
