Background Drug eluting stents (DES) are used in the majority of patients undergoing percutaneous coronary intervention (PCI). Factors associated with the use of bare metal stents (BMS) for patients undergoing primary PCI for ST elevation myocardial infarction (STEMI) have not been adequately explored. The objective of this study was to evaluate factors associated with BMS use in STEMI patients undergoing primary PCI. Methods Patients undergoing primary PCI for STEMI between January 2008 and February 2015 were retrospectively identified. Patients who received both a DES and BMS were included in the DES group and patients receiving balloon angioplasty only were excluded. Baseline demographics, angiographic variables, procedure related variables and in-hospital events were collected. Multivariate analysis was performed to identify factors associated with BMS use. Results Eight hundred and sixty-five patients underwent primary PCI for STEMI during the study period. Seventy-two patients (8.3%) received balloon angioplasty only and were excluded, yielding 793 patients for the study cohort. Three hundred fifty-two patients (44%) received BMS and 441 patients (56%) received DES. Patients receiving DES had a higher prevalence of diabetes mellitus, prior myocardial infarction, prior PCI, left anterior descending artery culprit location and Medicaid Insurance compared to those receiving BMS. Patients receiving BMS had a higher prevalence of cardiogenic shock and right coronary artery culprit location. Unadjusted in-hospital mortality was significantly higher for patients receiving BMS compared to patients receiving DES, 11.1% vs 3.2%, respectively, p less then 0.0001. Multivariate predictors of BMS use were cardiogenic shock (OR 30.3; 95% CI 11.25 to 81.73) and diabetes mellitus (OR 2.99; 95% CI 1.04 to 8.64). Conclusion In a contemporary series of patients undergoing primary PCI for STEMI, BMS were used in 44% of patients and independent factors associated with BMS use were cardiogenic shock and diabetes mellitus.Rapid deployment aortic valve prostheses have become a common solution for aortic valve replacement. While >mild prognostic paravalvular leaks are not infrequent, their treatment is not yet clear. We report the case of an 82-year-old man that presented with acute heart failure. Previously implanted rapid deployment bioprosthetic aortic valve (Intuity Elite, Edwards Lifesciences, Irvine, California) presented a significant paravalvular leak that seemed to be secondary to valve underexpansion. Percutaneous balloon post dilation was performed and resulted in better expansion of the valve and its sealing skirt with a significant reduction of the leak.Myocardial bridging is a common coronary abnormality often associated with left ventricular hypertrophy. It can be noted incidentally on coronary angiography by findings of systolic narrowing of the involved coronary artery. We present the case of a 59-year-old woman that presented with a non-ST elevation myocardial infarction. She had a history of angina and workup 9-months prior with CT coronary angiography that revealed an intra-myocardial course of the left anterior descending coronary artery (LAD) with minimal stenosis and no concomitant coronary artery disease. Invasive coronary angiography now demonstrated apparent myocardial bridging associated with a severe fixed stenosis of the LAD without change in diameter with nitroglycerin injection. Due to persistent symptoms, surgical myotomy was attempted and then aborted because of difficulty unroofing the LAD due to surrounding fibrosis. GSK3787 price Coronary artery bypass grafting (CABG) was then successfully performed using a left internal mammary artery graft. The patient had complete resolution of her chest pain and was without functional limitation at 3-month follow-up. This case highlights possible sequelae of myocardial bridging and suggests that, in rare cases, fixed obstruction of the involved coronary artery may occur in the setting of fibrosis of the bridged segment. In such cases, surgical myotomy may not be feasible and CABG may be required.Background Physician in triage (PIT) has been used as a potential solution to emergency department (ED) overcrowding and to decrease ED length of stay (LOS). This study examined the relationship between computerized tomography (CT) utilization of PIT and ED patient volumes. We hypothesized that despite the pressure on PIT to improve throughput on the busiest days, they will continue to utilize CT at the same rate. Methods This retrospective chart review evaluated CT ordering patterns of PIT on patients with abdominal pain who presented to the ED over a 6-year period. CT utilization rate was calculated on days with the lowest 5% (LD5) and highest 5% (HD5) volumes based on average yearly volume. CT positive and negative rates were correlated with volume using Chi square analysis. Odds ratio and confidence intervals were calculated for the magnitude of effect difference. Results We found no statistically significant difference in CT utilization rate on HD5 vs LD5 (p = 0.833). There was a statistically significant increase in the rate of negative CT scans on HD5 (p = 0.046) which represented a 17% relative difference. LOS was longer on HD5 (p = 0.013) and when a CT scan was ordered (p less then 0.001). Conclusion No difference was found in the rate at which the PIT ordered CT scans on high volume vs low volume days. The rate of CT scans without clinically relevant findings did increase slightly on high volume days. LOS was longer on high volume days and when a CT was ordered.Background Patients who present with atrial fibrillation (AF) or flutter with rapid ventricular response (RVR) and hemodynamic stability may be managed with either an intravenous (IV) nondihydropyridine calcium channel blocker (CCB) or a beta-blocker (BB). Patients without improved heart rates may need to switch to, or add, a second AV nodal blocker. Objective To evaluate the incidence of rate control achievement and bradycardia in patients in AF or atrial flutter with RVR who receive both an intravenous CCB and a BB. Methods A retrospective chart review of patients who received concomitant intravenous CCB or BB for the treatment of rapid AF or atrial flutter from April 2016 through July 2018 in the emergency department. Patients were excluded if the second agent was ordered but not administered, or if they received IV amiodarone or digoxin. Results A total of 136 patients were included in the analysis, and of those, 46% (n = 62) of patients achieved a heart rate less then 110 bpm without bradycardia, and 3.
