L Wood, M Czyz, S Forster, Bronek M Boszczyk
BACKGROUND: Cervical radiculopathies are rarely caused by vertebral artery loop formation, which is estimated to be present in less than 3% of patients. It is uncertain what causes the loop formation: some propose an association with spondylotic changes or trauma, whilst others suggest hypertension and atherosclerosis may be responsible. CASE REPORT 1: A 35-year-old male patient presented with signs and symptoms of cervical radiculopathy that was not improved with anterior cervical discectomy and fusion surgery performed 2 years beforehand...

Cardiovascular magnetic resonance (CMR) perfusion has been established as a useful imaging modality for the detection of coronary artery disease (CAD). However, there are several limitations when applying standard, ECG-gated stress/rest perfusion CMR to patients with atrial fibrillation (AF). In this study we investigate an approach with no ECG gating and a rapid rest/stress perfusion protocol to determine its accuracy for detection of CAD in patients with AF. 26 patients with AF underwent a rapid rest/regadenoson stress CMR perfusion imaging protocol, and all patients had X-ray coronary angiography...

REVIEW
Brian J Kinsman, Haley N Nation, Sean D Stocker
PURPOSE OF REVIEW: The central nervous system plays a pivotal role in the regulation of extracellular fluid volume and consequently arterial blood pressure. Key hypothalamic regions sense and integrate neurohumoral signals to subsequently alter intake (thirst and salt appetite) and output (renal excretion via neuroendocrine and autonomic function). Here, we review recent findings that provide new insight into such mechanisms that may represent new therapeutic targets. RECENT FINDINGS: Implementation of cutting edge neuroscience approaches such as opto- and chemogenetics highlight pivotal roles of circumventricular organs to impact body fluid homeostasis...

Inappropriate left ventricular remodeling following myocardial infarction (MI) can result in subsequent severe dysfunction. In this study, we tested the hypothesis that decellularized pericardium (DP) or seeded pericardial patch with autologous adipose-derived mesenchymal stem cells (ADMSCs) could be safely used in a MI scar and could improve heart function. Twelve rabbits were randomly divided into three equal groups. Four weeks after MI induction by ligation of the left anterior descending artery in 12 rabbits, animals of G1 (n = 4) received DP patch with labeled ADMSCs...

PURPOSE: In Le Fort 1 osteotomy when a maxillary impaction is necessary, surgeons have to face different anatomical problems. (1) To determine the best bone resection route, they have to consider the situation of dental roots, infraorbital foramen and maxillary artery. (2) In case of Le Fort 1 osteotomy combined with a mandibular sagittal split osteotomy, the palate has to be replaced in horizontal position although there is no anatomical landmark. (3) In case of Gummy smiles, it can be due to either long face or short upper lip...

BACKGROUND: Out-of-hospital cardiac arrest (OHCA) results in significant morbidity and mortality, primarily from neurologic injury. Predicting neurologic outcome early post-OHCA remains difficult in patients receiving targeted temperature management. METHODS AND RESULTS: Retrospective analysis was performed on consecutive OHCA patients receiving targeted temperature management (32-34°C) for 24 hours at a tertiary-care center from 2008 to 2012 (development cohort, n=122)...

INTRODUCTION: Infected femoral pseudoaneurysms are a common presentation in intravenous drug users with little consensus as to the optimum management of these patients. Whilst emergency revascularisation options are available, excision and ligation of the femoral artery remains the most common operative intervention but risks leaving the patient with critical ischaemia or intermittent claudication. This case series reviewed the outcomes of 4 patients who underwent excision-ligation without revascularisation of an infected femoral pseudoaneurysm at a district general hospital...

OBJECTIVES: The aim of the present study was to evaluate, in low-to-intermediate pre-test probability patients who were referred for coronary computed tomography angiography (CTA) and did not show obstructive coronary artery disease (CAD), whether an intramural course of a coronary artery is associated with worse outcome compared with patients without an intramural course of the coronary arteries. BACKGROUND: The prognostic value of an intramural course of the coronary arteries on coronary CTA in patients without obstructive CAD is not well-known...

OBJECTIVES: The purpose of this study was to evaluate the prognostic value of sequential hybrid imaging strategy in which positron emission tomography (PET) perfusion imaging is performed selectively in patients with suspected obstructive coronary artery disease (CAD) on coronary computed tomography angiography (CTA). BACKGROUND: Coronary CTA is an accurate diagnostic test for excluding obstructive CAD. However, the positive predictive value is suboptimal. METHODS: We investigated 864 consecutive symptomatic patients with intermediate probability of CAD who adhered to the sequential imaging approach...

BACKGROUND: Obstetric patients comprise a limited portion of intensive care unit patients, but they often present with unfamiliar conditions and exhibit the potential for catastrophic deterioration. This study evaluated the maternal and neonatal outcomes of respiratory failure during pregnancy. METHODS: Information on 71 patients at >25 weeks gestation in the ICU with respiratory failure was recorded between 2009 and 2013. The characteristics and outcomes of mothers and fetuses were determined through a retrospective chart review and evaluated using Student's t test, chi-square test, and Fisher's exact test...

Spinal cord injury remains a major adverse event of extended thoracic and thoracoabdominal aortic surgical procedures. Preoperative identification of the Adamkiewicz artery and prompt reattachment of the targeted intercostal arteries during operation should contribute to preventing spinal cord injury. In this report, we describe a simple and definite identification of the critical intercostal artery during extended descending and thoracoabdominal aortic surgical procedures.

A 9-year-old child presented with syncope during exercise. He received a diagnosis of congenital atresia of the left main coronary artery by angiography. He underwent successful coronary artery bypass grafting. On the third postoperative day, he experienced acute, precordial chest pain. An urgent computed tomographic scan showed an unrecognized anomalous origin of the right coronary artery (RCA) with a 1.5-cm intramural course. He was taken back to the operating room to undergo unroofing of the RCA. This case highlights the difficulty involved in making two rare diagnoses that can cause the same exact symptoms in a patient and the surgical challenges associated with it...

We report three cases of coronary fistula aneurysm associated with mitral valve insufficiency. The patients were referred to our cardiovascular department because of exertional dyspnea. Echocardiography showed severe mitral valve insufficiency resulting from leaflet flail or prolapse and normal left ventricular function. In all three cases, preoperative coronary angiography showed coronary-to-pulmonary artery fistula associated with significant aneurysm of the fistulous tract. All patients underwent uneventful mitral valve repair and external ligation of the fistulas...

We present the case of a 55-year-old woman admitted for a coronary artery bypass operation because of three-vessel coronary artery disease based on angiographic findings and clinical symptoms. Unexpected intraoperative findings with diffuse tissue thickening of the ascending aorta and coronary arteries indicated an alternate pathogenesis rather than coronary artery atherosclerosis. Histopathologic findings and clinical evaluation could confirm IgG4-related disease (IgG4-RD). IgG4-RD is a newly recognized fibroinflammatory condition that can present in a variety of organs and is characterized by common histopathologic features...

This study evaluated the diagnostic performance of ultrasound elastography (USE) using carotid arterial pulsation and determined the reproducibility of USE for thyroid nodules. A total of 148 patients with 173 thyroid nodules participated. The mean elasticity contrast index (ECI) was significantly higher in malignant nodules (3.1 ± 1.5) than in benign nodules (1.7 ± 0.8) (p < 0.001). When a cut-off ECI value of 3.5 was used, the diagnostic accuracy (78.6%) of gray-scale ultrasound (US) + ECI was the highest compared with that of the gray-scale US (76...

BACKGROUND: Cardiac valve disease is common in patients with end-stage heart failure undergoing left ventricular assist device implantation (LVAD). The aim of this study was to determine if preoperative mitral regurgitation (MR) affects outcomes and hemodynamics in patients after LVAD implantation. METHODS: From March 2006 through May 2015, 238 consecutive patients underwent LVAD implantation. Patient cohorts included less than moderate to severe MR (< moderate-severe, n = 195) and greater than or equal to moderate to severe MR (≥ moderate-severe, n = 43)...

BACKGROUND: Major aortopulmonary collateral arteries (MAPCAs) are frequently found in association with pulmonary atresia with ventricular septal defect (PA/VSD). However, some patients with MAPCAs do not have PA/VSD but have a variety of other "atypical" anatomic diagnoses. METHODS: This was a retrospective review of patients with MAPCAs and atypical anatomy. The 50 patients with MAPCAs could be divided into two subgroups: (1) single ventricle anatomy (n = 33) and (2) two ventricle anatomy (n = 17)...
