Background: Neutrophil to lymphocyte ratio (NLR) has been studied as a measure of inflammation and as a prognosticating factor in various medical conditions including neoplastic, inflammatory and cardiovascular. The prognostic role of NLR in predicting mortality in patients with aortic stenosis undergoing surgical aortic valve replacement (AVR) has not been studied. The aim of our study is to explore the utility of NLR as a predictor of both, short and long-term mortality, in patients undergoing surgical AVR.

Atrial myxomas are the most common primary cardiac tumors. Patients with left atrial myxomas generally present with mechanical obstruction of blood flow, systemic embolization, and constitutional symptoms. We present a case of an unusually large left atrial myxoma discovered incidentally in a patient with longstanding dyspnea being managed as bronchial asthma.

Introduction: Inadvertent malposition of a pacemaker ventricular lead into the left ventricle is an uncommon event, and its actual incidence is probably unknown. It may be underestimated and underreported because of a possible asymptomatic course. A 12-lead electrocardiogram is important to confirm proper placement.

Neutrophil/lymphocyte ratio (NLR) is the strongest white blood cell predictor of adverse outcomes in stable and unstable coronary artery syndromes. The aim of our study was to explore the utility of NLR in predicting long-term mortality in patients with non-ST-segment elevation myocardial infarction (NSTEMI). Consecutive patients with NSTEMI at Staten Island University Hospital were evaluated for study inclusion.

Lately, there has been an increased incidence of late stent thrombosis; especially following Drug eluting stent (DES) implantation. Several factors are associated with an increased risk of stent thrombosis, including the procedure itself, patient and lesion characteristics, stent design, and premature cessation of anti-platelet drugs. We present a case of late stent thrombosis (LST) following DES implantation after a period of 68 months, making it the longest reported case of LST reported in the literature, despite the use of dual anti-platelet therapy.

Breast augmentation is one of most commonly performed cosmetic surgical procedures. Pneumothorax has been reported as a rare complication of breast augmentation but the incidence is not known. Our patient presented with dyspnea on exertion about 6 days following breast augmentation.

Introduction: Bifurcation lesions have traditionally presented a unique problem for interventional cardiologists because of their inherent anatomy and risk of closure of the side branch, after a percutaneous intervention for the primary lesion of the main branch.

Case Presentation: We report the case of a 57-year-old man who presented with acute ST-segment elevation myocardial infarction secondary to a 100% occlusion at the ostium of first diagonal (D1) branch. Patient also had a 70% stenosis of the mid-segment of the left anterior descending (LAD) coronary artery at the D1 branching point (1,1,1 Medina classification).
