BACKGROUND: Anomalous aortic origin of a coronary artery (AAOCA) is the second leading cause of sudden death in youth. However, its significance and optimal management in adults is poorly understood. Our objective is to characterize AAOCA in a large single-center adult cohort based on coronary anatomic variants and surgical management strategies. METHODS: We reviewed imaging, clinic, and operative reports for 645 adults with an encounter diagnosis code of congenital coronary anomaly from July 2015 to July 2017...

BACKGROUND: Reconstruction of the intervalvular fibrosa (IVF) for invasive double-valve infective endocarditis (IE) is a technically challenging operation. This study presents the long-term outcomes of two surgical techniques for IVF reconstruction. METHODS: From 1988 to 2017, 138 patients with invasive double-valve IE underwent surgical reconstruction of the IVF, along with double-valve replacement (Commando procedure, n = 86) or aortic valve replacement with mitral valve repair (hemi-Commando procedure, n = 52)...

SESSION TYPE: Cancer Student/Resident Case Report PostersPRESENTED ON: Tuesday, October 23, 2012 at 01:30 PM - 02:30 PMINTRODUCTION: The comman Anterior mediastinal masses found in the anterior mediastinum are thymomas, lymphomas, germ cell tumors, congenital cysts, intrathoracic thyroid tissue, and parathyroid lesions1. Common clinical presentations of the mediastinal masses include dyspnea on exertion, arrhythmias, right-sided heart failure, pericarditis, pericardial effusion, and syncope.1 Thymomas represent 20 percent of all mediastinal neoplasms in adults and is found in 15 percent of patients with myasthenia gravis...

BACKGROUND: Clinical studies on intracoronary stem cell infusion in patients with acute myocardial infarction (AMI) have shown promising results for left ventricular ejection fraction (LVEF). However, preclinical studies have shown that intramyocardial cell injection is better than the intracoronary approach. OBJECTIVE: To test safety and feasibility of intramyocardial cell injection and left ventricular electromechanical mapping (EMM) early after AMI. DESIGN: On day 10...

Critical illness is associated with increased oxidative stress that may give rise to the formation of lipid hydroperoxides (LOOH) and various secondary degradation products such as fragmented phosphatidylcholine (FPC) and lipids related to the platelet-activating factor (PAF). Because some oxidized phospholipids are potent proinflammatory agents, we measured the concentration of LOOH, FPC, and PAF-like activity in blood plasma of 36 patients who had undergone cardiac surgery and developed postoperative complications associated with systemic inflammatory response syndrome (SIRS) or multiple organ failure (MOF)...

The aim of this study was to evaluate somatosensory evoked potentials (SEP) as a simple neurophysiological monitoring method in supra-aortal balloon test occlusions (BTO). The 13 patients examined had carcinoma of the larynx (n = 6), nasopharyngeal malignancy (n = 3), sphenoid meningioma (n = 2), mycotic aneurysm (n = 1), and a tumor of the carotid body (n = 1). Transfemoral balloon occlusion of the internal carotid artery was maintained for 30 min and monitored both clinically and by SEP. None of the 13 patients showed neurological deficits or pathological changes in the SEP...

After operations with cardiopulmonary bypass, patients often show early symptoms of the systemic inflammatory response syndrome (SIRS). Potential mediators of SIRS include the platelet-activating factor (PAF), which has been linked to septic shock and multiple organ dysfunction. We studied the effect of cardiac surgery on PAF acetylhydrolase, the PAF-degrading plasma enzyme, as well as the relationship between the enzyme and the postoperative state of the patients. PAF acetylhydrolase activity decreased by 38+/-8% after instituting cardiopulmonary bypass because of plasma dilution and returned to near-preoperative levels within 6 h postsurgery...

OBJECTIVE: To determine the prognostic significance of altered plasma viscosity and erythrocyte aggregation in unstable angina. DESIGN: A prospective study of 96 consecutive patients with unstable angina allocated to one of two groups according to predefined threshold values for plasma viscosity and erythrocyte aggregation at study entry. The patients received a standardised treatment and were followed up for six months or until angioplasty or bypass surgery. MAIN OUTCOME MEASURE: Frequency of myocardial infarction...
