Background Pial arteriovenous fistula (AVF) is composed of one or more direct arterial feeding vessels with a single draining vein without nidus. A patient with the disease with high-flow AV shunting in the neonatal period not only suffers from high-output cardiac failure but also shows secondary neurological sequelae. In vein of Galen aneurysmal malformation, superior vena cava (SVC) flow measurements provide useful prognostic information. Case Presentation We measured serial SVC flow in a male infant with pial AVF...

BACKGROUND: Congenital heart disease (CHD) is a common condition in children in Sub-Saharan Africa (SSA), where it is associated with poor outcomes. Diagnosis of CHD in SSA depends essentially on echocardiography, which is available only in few urban referral centers. Our aim was to assess time changes in the pattern of referral for pediatric echocardiography and the subsequent diagnosis of structural CHD in a major SSA city. METHODS: All pediatric echocardiography performed between 2004 and 2013 at the echocardiography laboratory of the Yaounde General Hospital were reviewed...

CONTEXT: Making a diagnosis can be difficult for learners as they must integrate multiple clinical variables. Diagnostic schemes can help learners with this complex task. A diagnostic scheme is an algorithm that organises possible diagnoses by assigning signs or symptoms (e.g. systolic murmur) to groups of similar diagnoses (e.g. aortic stenosis and aortic sclerosis) and provides distinguishing features to help discriminate between similar diagnoses (e.g. carotid pulse). The current literature does not identify whether scheme layouts should guide learners to reason one step at a time in a terminally branching scheme or weigh multiple variables simultaneously in a hybrid scheme...

A system for collection, distribution, and long distant, asynchronous interpretation of cardiac auscultation has been developed and field-tested in rural China. We initiated a proof-of-concept test as a critical component of design of a system to allow rural physicians with little experience in evaluation of congenital heart disease (CHD) to obtain assistance in diagnosis and management of children with significant heart disease. The project tested the hypothesis that acceptable screening of heart murmurs could be accomplished using a digital stethoscope and internet cloud transmittal to deliver phonocardiograms to an experienced observer...

Physiological mechano-acoustic signals, often with frequencies and intensities that are beyond those associated with the audible range, provide information of great clinical utility. Stethoscopes and digital accelerometers in conventional packages can capture some relevant data, but neither is suitable for use in a continuous, wearable mode, and both have shortcomings associated with mechanical transduction of signals through the skin. We report a soft, conformal class of device configured specifically for mechano-acoustic recording from the skin, capable of being used on nearly any part of the body, in forms that maximize detectable signals and allow for multimodal operation, such as electrophysiological recording...

A 3-day-old Hereford heifer calf presented for evaluation of lethargy and dyspnea, with persistent hypoxia despite supplemental oxygen therapy. A grade III/VI right apical systolic murmur was noted during cardiac auscultation. Echocardiography revealed a double-outlet right ventricle with an intact interventricular septum and concurrent hypoplastic left ventricle and tricuspid valve dysplasia. Post-mortem examination revealed additional congenital anomalies of ductus arteriosus, patent foramen ovale, and persistent left cranial vena cava...

Myxomas are the most common benign cardiac tumors, which are considered emergency surgery. The resection should not be delayed because 8-9% of affected patients may die due to intracardiac blood flow obstruction. We presente a clinical case of a 47 year old female, history of dyslipidemia. Disease starts with retrosternal oppression feeling, dyspnea on moderate exercise, dizziness, pain in joints hands. Arrhytmic heart sounds, diastolic mitral murmur II/IV, breth sounds present, no lymph. Laboratory: hemoglobin 11...

INTRODUCTION: The Mucopolysaccharidoses (MPS) are rare inherited metabolic disorders. They are characterized by the progressive systemic deposition of Glycosaminoglycans (GAGs). GAGs accumulate in the myocardium and the cardiac valves. Enzyme Replacement Therapy (ERT) is available for MPS I, II, and VI. However, ERT does not appear to improve cardiac valve disease in patients with valve disease present at the start of ERT. AIM: To evaluate the cardiac involvement in Egyptian children with MPS...

Introduction. Inflammatory pseudotumor is an uncommon entity, and its cardiac origin is exceedingly rare. Case History. A previously healthy 27-year-old man was found to have a systolic murmur during preemployment screening evaluation. A transthoracic echocardiogram revealed a 4 × 2.5 cm mass originating from the right ventricle (RV) outflow tract extending into the aortic root. A computed tomography guided biopsy confirmed an IgG4-related inflammatory pseudotumor. Patient was started on oral prednisone with subsequent reduction in mass size...

The Budd-Chiari syndrome (BCS) is a rare disorder caused by the obstruction of the hepatic veins or the inferior vena cava (IVC) at the suprahepatic level. This syndrome is developed by either hepatic vein thrombosis or mechanical venous obstruction and leads to centrilobular hepatic congestion with the subsequent development of fibrosis and cirrhosis. Intracardiac tumors have been rarely reported as a cause of the BCS. These tumors usually originate from the atrial septum. Very rarely, they arise either from the junction of the IVC and the right atrium or from the Eustachian valve...

BACKGROUND: Effectiveness of simulation-based education in cardiac auscultation training is controversial, and may vary among a variety of heart sounds and murmurs. We investigated whether a single auscultation training class using a cardiology patient simulator for medical students provides competence required for clinical clerkship, and whether students' proficiency after the training differs among heart sounds and murmurs. METHODS: A total of 324 fourth-year medical students (93-117/year for 3 years) were divided into groups of 6-8 students; each group participated in a three-hour training session using a cardiology patient simulator...

In the perioperative period, the emergency department or the intensive care unit accurate assessment of variable chest pain requires meticulous knowledge, diagnostic skills, and suitable usage of various diagnostic modalities. In addition, in polytrauma patients, cardiac injury including aortic dissection, pulmonary embolism, acute myocardial infarction, and pericardial effusion should be immediately revealed and treated. In these patients, arrhythmias, mainly tachycardia, cardiac murmurs, or hypotension must alert physicians to suspect cardiovascular trauma, which would potentially be life threatening...

BACKGROUND: Mean systolic blood pressure in apparently healthy cats has been reported as approximately 125 mmHg using direct assessment, but there is greater variability in reported values using indirect assessment. Increasing age and the white-coat effect are associated with increased systolic blood pressure.

Aditya Singh Kutiyal, Mradul Kumar Daga
Ruptured Sinus of Valsalva (RSOV) is a rarely seen disease condition. RSOV can have varied presentations from being asymptomatic with just a cardiac murmur to profound hypotension. There has been simultaneous occurrence of RSOV with Infective Endocarditis (IE) in literature. Glomerulonephritis has also been reported in approximately 20% patients with IE. Large amount of proteinuria or decline in kidney functions is rarely encountered and mostly this finding has been incidental on routine evaluation. The co-existence of all the three conditions in a single patient is rare...

Crisscross heart is a rare cardiac malformation characterized by crossing of the inflow streams of the two ventricles due to a twisting of the heart about its long axis. The developmental mechanisms and causes of crisscross heart remain unknown. Neonates present with cyanosis and a systolic murmur. In this study, we report a case of crisscross heart with situs inversus, concordant atrioventricular and ventriculo arterial connection with ventricular septal defect and pulmonary stenosis, and review the literature on this rare cardiac malformation...

BACKGROUND: Auckland City Hospital (ACH) established a Heart Murmur Clinic (HMC) with the aim of providing prompt assessment of patients with asymptomatic systolic murmurs. This may lead to early intervention and improved outcomes if significant structural heart disease is detected and reassurance if no significant findings are found. Similar clinics for children have proven beneficial; the benefit of a HMC in an adult population has been difficult to determine. AIM: To review the clinical demographics and echocardiographic information of patients presenting to our HMC, to assess what proportion of significance structural heart disease had and determine the common structural abnormalities in this population...

Multiple reports have shown that echocardiograms are neither cost-effective nor of high diagnostic yield for a number of indications. This study sought to evaluate the impact of indications and provider type on the diagnostic yield of first-time outpatient pediatric echocardiograms. All initial echocardiograms interpreted at our institution from February 2009 to December 2014 were reviewed retrospectively. Positive findings were defined as any abnormality of structure or function. Ordering physicians were grouped as Primary Care, Subspecialist, or Cardiologist...
