Anomalous left anterior descending artery diagnosed on pulmonary artery computed tomography.

Am J Emerg Med 2019 Apr 12. Epub 2019 Apr 12.

Department of Emergency Medicine, Baylor Scott and White Health, 2401 S 31(st) Street, Temple, TX 76508, United States of America.

Typically, the left anterior descending artery (LAD) and left circumflex artery (LCX) arise from the left main coronary artery. However, uncommon coronary anomalies may be found in clinical practice. This case presents with a rare finding where the LAD originates from the right coronary artery (RCA) separately from the LCX and takes an interarterial pathway to reach its perfusion territory.

Atrial-Esophageal Fistula After Catheter Ablation: Diagnosing and Managing a Rare Complication of a Common Procedure.

Am J Case Rep 2019 Apr 20;20:557-561. Epub 2019 Apr 20.

Department of Cardiology, Providence Hospital, Michigan State University, Detroit, MI, USA.

BACKGROUND Atrial fibrillation is considered the most common cardiac arrhythmias in the United States with rate and rhythm control strategies traditionally used for management. If patients are intolerant to class I or class III anti-arrhythmic medications, catheter ablation may be used as a rhythm control strategy. As catheter ablation becomes more commonplace, so too do the procedure-related complications, which include tamponade, total arterio-venous fistula, pulmonary vein stenosis, and atrial-esophageal fistula.

Eur Respir Rev 2019 Jun 17;28(152). Epub 2019 Apr 17.

Woolcock Institute of Medical Research and Northern Clinical School, Faculty of Medicine and Health, The University of Sydney, Sydney, Australia.

Asthma remains an important disease worldwide, causing high burden to patients and healthcare systems and presenting a need for better management and ultimately prevention and cure. Asthma is a very heterogeneous condition, with many different pathophysiological processes. Better measurement of those pathophysiological processes are needed to better phenotype disease, and to go beyond the current, highly limited measurements that are currently used: spirometry and symptoms.

Imaging of pulmonary hypertension: Pictorial essay.

Chest 2019 Apr 11. Epub 2019 Apr 11.

Pulmonary hypertension (PH) is an end result of a diverse array of complex clinical conditions, which invoke hemodynamic and pathophysiological changes in the pulmonary vasculature. Many patients' symptoms begin with dyspnea on exertion for which screening tests like chest roentgenograms and more definitive non-invasive tests like CT scans are ordered initially. It is imperative that clinicians are cognizant of subtle clues on these imaging modalities that alert them to the possibility of PH. Read More

Morphological Assessment of the Tricuspid Apparatus and Grading Regurgitation Severity in Patients With Functional Tricuspid Regurgitation: Thinking Outside the Box.

JACC Cardiovasc Imaging 2019 Apr;12(4):652-664

Department of Cardiac, Thoracic, and Vascular Sciences, University of Padua School of Medicine, Padua, Italy; IRCCS, Instituto Auxologico Italiano, S. Luca Hospital, University of Milano-Biococca, Milan, Italy.

Current guidelines recommend transthoracic echocardiography to assess patients with functional tricuspid regurgitation (FTR) because it provides information regarding the presence of structural abnormalities of the tricuspid valve (TV), allows measurement of tricuspid annulus diameter, and evaluates severity of FTR by integrating data obtained from 2D and Doppler echocardiography. Critical components of the noninvasive evaluation include information regarding TV anatomy, tricuspid regurgitation severity, right ventricular size and systolic function, and associated findings such as estimated pulmonary artery pressure. However, most of the parameters included in the current recommendations to assess FTR are derived from the experience and knowledge developed about the mitral valve and have been transferred from the left to the right side of the heart without accounting for differences in anatomy of the tricuspid and mitral apparatus or for differences in hemodynamic environment in which the TV operates compared to its left counterpart.

Tricuspid Valve Imaging and Intervention in Pediatric and Adult Patients With Congenital Heart Disease.

JACC Cardiovasc Imaging 2019 Apr;12(4):637-651

Division of Pediatric Cardiology, Mayo Clinic, Rochester, Minnesota; Division of Cardiovascular Diseases, Mayo Clinic, Rochester, Minnesota. Electronic address:

Tricuspid valve abnormalities in congenital heart disease comprise a wide spectrum, with the most common being Ebstein anomaly and tricuspid valve dysplasia. Tricuspid valve dysfunction may also be secondary to other types of congenital heart disease, including functional tricuspid regurgitation seen in right heart volume overload conditions, such as atrial septal defect and repaired tetralogy of Fallot with severe pulmonary valve regurgitation. Congenitally corrected transposition and Mustard and Senning procedures maintain the right ventricle as the systemic ventricle, and the tricuspid valve is subject to unique hemodynamic stress not typically seen in normal circulation.

The first 200 years of cardiac auscultation and future perspectives.

J Multidiscip Healthc 2019 6;12:183-189. Epub 2019 Mar 6.

Department of Cardiology, Local Health Unit Lecce, Lecce, Italy.

Cardiac auscultation - even with its limitations - is still a valid and economical technique for the diagnosis of cardiovascular diseases, and despite the growing demand for sophisticated imaging techniques, clinical use of the stethoscope in medical practice has not yet been abandoned. In 1816, René-Théophile-Hyacinthe Laënnec invented the stethoscope, while examining a young woman with suspected heart disease, giving rise to mediated auscultation. He described in detail several heart and lung sounds, correlating them with postmortem pathology. Read More

Sternal Wound Infections, Risk Factors and Management - How Far Are We? A Literature Review.

Heart Lung Circ 2019 Feb 2. Epub 2019 Feb 2.

Department of Cardiothoracic Surgery, Liverpool Heart and Chest, Liverpool, UK. Electronic address:

Sternal wound infection (SWI) is one of the potential complications post cardiac surgery, and despite refined surgical techniques such as smaller incisions, antibiotic therapy, and optimised glycaemic control, the incidence rate is between <1% in elective cases with low risk factors and as high as 25% in patients with extensive risk factors. The presence of SWI will increase the perioperative morbidity and mortality rates and prolong the patient's hospital stay, therefore the prevention and diagnosis with appropriate management of such adverse outcomes at an early stage is important to prevent further progression as it can be fatal when the mediastinal structures are affected. Currently, the diagnosis typically consists of three main stages: clinical, biochemical including microbiology studies and imaging studies. Read More

129Xe MRI detects ventilation deficits in pediatric stem-cell transplant patients unable to perform spirometry.

Eur Respir J 2019 Mar 7. Epub 2019 Mar 7.

Center for Pulmonary Imaging Research, Division of Pulmonary Medicine and Department of Radiology, Cincinnati Children's Hospital Medical Center, Cincinnati, OH.

Background: Early detection of pulmonary morbidity following hematopoietic stem cell transplantation (HSCT) remains an important challenge for intervention, primarily due to the insensitivity of spirometry to early change, and in pediatrics, patient compliance provides additional challenges. Regional lung ventilation abnormalities in pediatric HSCT patients were quantified using hyperpolarized Xe magnetic resonance imaging (MRI) and compared to spirometry.

Methods: Medically-stable, pediatric allogeneic HSCT patients (n=23, ages 6-16) underwent an outpatient MRI where regional ventilation was quantified with a breath-hold of hyperpolarized Xe gas. Read More

Resting and Exercise Doppler Hemodynamics: How and Why?

Heart Fail Clin 2019 Apr 2;15(2):229-239. Epub 2019 Feb 2.

Department of Cardiology, The Alfred, 55 Commercial Road, Melbourne, Victoria 3004, Australia; Baker Heart and Diabetes Institute, 75 Commercial Road, Melbourne, Victoria 3004, Australia.

Exercise intolerance is the clinical hallmark of the failing heart. Evidence of hemodynamic derangement is not always present at rest, often necessitating dynamic challenges to accentuate abnormalities. Although cardiac catheterization, particularly with exercise, remains the gold standard method for hemodynamic assessment, it is limited by practicality, access, risk, and its invasive nature; consequently, there is a need to better understand noninvasive measures.

Congenital Zika Syndrome: The Main Cause of Death and Correspondence Between Brain CT and Postmortem Histological Section Findings From the Same Individuals.

Top Magn Reson Imaging 2019 Feb;28(1):29-33

Federal University of Pernambuco, Recife, Brazil.

In the present case series, the cause of death of infants diagnosed with congenital Zika syndrome (CZS) was lung disease (pneumonia and sepsis with massive pulmonary aspiration), probably secondary to dysphagia and reflux. The main findings in infants with a confirmed diagnosis of CZS who died were as follows: (1) calcification and hypoplasia of the lentiform nuclei, hypoplasia of the caudate nuclei, and calcification at the cortical-subcortical junction was noted in all cases (100%) and calcification of the caudate nuclei was noted in 66.7% of cases; (2) calcification in the brainstem and along the lateral wall of the lateral ventricles was noted in only the case with arthrogryposis (33.

A unique case of ectopic Cushing's syndrome from a thymic neuroendocrine carcinoma.

Endocrinol Diabetes Metab Case Rep 2019 Feb 22;2019. Epub 2019 Feb 22.

Departments of Endocrinology, Diabetes & Metabolism, Cleveland Clinic, Cleveland, Ohio, USA.

Ectopic adrenocorticotropic hormone (ACTH) production leading to ectopic ACTH syndrome accounts for a small proportion of all Cushing's syndrome (CS) cases. Thymic neuroendocrine tumors are rare neoplasms that may secrete ACTH leading to rapid development of hypercortisolism causing electrolyte and metabolic abnormalities, uncontrolled hypertension and an increased risk for opportunistic infections. We present a unique case of a patient who presented with a mediastinal mass, revealed to be an ACTH-secreting thymic neuroendocrine tumor (NET) causing ectopic CS. Read More

The Spectrum of Hepatic Involvement in Patients With Telomere Disease.

Hepatology 2019 Feb 21. Epub 2019 Feb 21.

Liver Diseases Branch, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, Bethesda, MD.

Loss-of-function mutations in genes that encode for components of the telomere repair complex cause accelerated telomere shortening. Hepatic involvement has been recognized as a cause of morbidity in telomere diseases, but very few studies have characterized the nature and extent of liver involvement in affected patients. We report the prevalence and characteristics of liver involvement in a large cohort of patients with telomere disease evaluated serially at the National Institutes of Health. Read More

Fetal iGRASP cine CMR assisting in prenatal diagnosis of complicated cardiac malformation with impact on delivery planning.

Clin Physiol Funct Imaging 2019 Feb 20. Epub 2019 Feb 20.

Department of Clinical Sciences Lund, Clinical Physiology, Skåne University Hospital, and Lund University, Lund, Sweden.

Limited visualization of the fetal heart and vessels by fetal ultrasound due to suboptimal fetal position, patient habitus and skeletal calcification may lead to missed diagnosis, overdiagnosis and parental uncertainty. Counselling and delivery planning may in those cases also be tentative. The recent fetal cardiac magnetic resonance (CMR) reconstruction method utilizing tiny golden-angle iGRASP (iterative Golden-angle RAdial Sparse Parallel MRI) allows for cine imaging of the fetal heart for use in clinical practice.

Prenatal diagnosis and management of congenital diaphragmatic hernia.

Best Pract Res Clin Obstet Gynaecol 2019 Jan 5. Epub 2019 Jan 5.

Academic Department of Development and Regeneration, Cluster Woman and Child, Biomedical Sciences, KU Leuven, Belgium; Clinical Department of Obstetrics & Gynaecology, KU Leuven, Leuven, Belgium; Institute for Women's Health, University College London, London, UK; European Reference Network on Rare and Inherited Congenital Anomalies "ERNICA". Electronic address:

Congenital diaphragmatic hernia is characterized by failed closure of the diaphragm, thereby allowing abdominal viscera to herniate into the thoracic cavity and subsequently interfering with normal lung development. At birth, pulmonary hypoplasia leads to respiratory insufficiency and persistent pulmonary hypertension (PHT), that is lethal in up to 32% of patients. In isolated cases, the outcome may be predicted prenatally by medical imaging and advanced genetic testing. Read More

Interstitial lung abnormalities: erecting fences in the path towards advanced pulmonary fibrosis.

Thorax 2019 May 5;74(5):506-511. Epub 2019 Feb 5.

Interstitial lung abnormalities, when present in members of undiagnosed family members recruited on the basis of familial interstitial pneumonia, or in undiagnosed research participants, have been associated with a syndrome that includes distinct sets of imaging abnormalities, restrictive physiological and exercise impairments, and an increased prevalence of histopathological findings, and genetic predictors, that have been noted in patients with idiopathic pulmonary fibrosis. Recent longitudinal studies have demonstrated that qualitative and quantitative assessments of interstitial abnormalities are associated with accelerated lung function decline, an increased rate of clinical diagnoses of interstitial lung disease and an increased rate of mortality. In this perspective, in addition to reviewing the prior information, four major efforts that could help the field of early pulmonary fibrosis detection move forward are discussed. Read More

Noncontrast Chest Computed Tomographic Imaging of Obesity and the Metabolic Syndrome: Part II Noncardiovascular Findings.

J Thorac Imaging 2019 Mar;34(2):126-135

Departments of Radiology.

The purpose of this review article is to acquaint the reader with the current state of the art for the noncardiovascular imaging biomarkers of metabolic syndrome found on noncontrast computed tomography (NCCT) of the chest and their prognostic significance. Routine chest NCCT includes quantitative information with regard to tissue density and organ volumes in the neck, chest, and upper abdomen. The specific imaging biomarkers that may be seen in association with metabolic syndrome include low thyroid iodine organification, hepatic steatosis, sarcopenia (muscle volume and density), demineralization of the thoracic and upper lumbar vertebral bodies, loss of axial skeletal muscle mass, premature lung inflammation, and an increased deposition of subcutaneous and visceral fat.
