INTRODUCTION
The American College of Cardiology (ACC) and the American Heart Association (AHA) publ ished pre-operative risk stratification guidelines in 2014. These guidelines have routinely been used by physicians to pre-operatively risk stratify patients. In this case report, a patient was found to have multi-vessel coronary artery disease post-operatively in the setting of unremarkable cardiac work-up preoperatively. This case highlights a limitation of the 2014 ACC/AHA guidelines.

INTRODUCTION
Amyloidosis is a rare disorder that involves the deposition of misfolded protein in extracellular tissue. Disease manifestations vary depending on the affected organs. Areas most often involved include the kidneys, gastrointestinal tract, heart, nervous system, and musculoskeletal system. The most common type is AL amyloidosis, in which plasma cells produce an abundance of a monoclonal proteins that affect numerous organ systems. A second variety, AA amyloidosis, is associated with inflammatory diseases such as rheumatoid arthritis and inflammatory bowel disease. Finally, a heritable version of amyloidosis mediated by mutations in the transthyretin protein (TTR) has a predilection for deposition in …

INTRODUCTION
Coronary subclavian steal (CSS) syndrome is a rare complication of coronary artery bypass graft surgery (CABG) involving the left internal mammary artery (LIMA) graft to the left anterior descending (LAD) artery. It results from stenosis of the left subclavian artery proximal to the LIMA, which compromises myocardial blood flow. The incidence of CSS syndrome is between 0.1-3.4% in the United States.1 Most cases occur as a result of long-standing subclavian stenosis due to progres-sion of the stenosis following CABG. We report a case of CSS syndrome, which presented as a non-ST elevation myocardial infarction (NSTEMI).

INTRODUCTION
Kounis syndrome is an acute coronary syndrome occurring secondary to an anaphylactic reaction. A wide variety of triggers such as drugs and environmental exposures have been described for the so-called allergic myocardial infarction. The pathophysiology of Kounis syndrome is thought to be due to the release of inflammatory mediators such as histamine and cytokines by mast cells and eosinophils resulting in either coronary vasospasm, myocardial infarction or stent thrombosis.
