Staphylococcus lugdunensis (S. lugdunensis) is a coagulase negative staphylococcus (CoNS) that can cause destructive infective endocarditis. S. lugdunensis, unlike other CoNS, should be considered to be a pathogen. We report the first case of S. lugdunensis endocarditis causing ventricular septal defect and destruction of the aortic and mitral valves. A 53-year-old male with morbid obesity and COPD presented with intermittent fever and progressive shortness of breath for 2 weeks. Chest examination showed bilateral basal crepitations, and a grade 2 systolic murmur along the right sternal border...

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...

A 3-month-old, 9.9 kg, male pit bull cross was referred for evaluation of collapse. A left basilar systolic heart murmur graded V/VI and a grade IV/VI right basilar systolic heart murmur were ausculted. Echocardiography showed severe pulmonic stenosis characterized by annular hypoplasia, leaflet thickening, and leaflet fusion. After 1 month of atenolol therapy, a pulmonic valve balloon valvuloplasty procedure was performed, and the intra-operative right ventricular pressure was reduced by 43%. Echocardiography, performed the following day, showed apparent rupture of a pulmonary valve leaflet and a membranous structure within the pulmonary artery consistent with a dissecting membrane...

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. HYPOTHESIS/OBJECTIVES: To report Doppler-derived blood pressure measurements from a large population of apparently healthy cats and to assess epidemiologic factors associated with recorded blood pressures...

Stent implantation using a Cheatham Platinum (CP) stent for coarctation of the aorta (CoA) is a promising treatment alternative to traditional surgical repair. However, there are no earlier reports in the literature focusing on use of this stent in a Taiwanese patient. Herein we report a 16-year-old boy with CoA presenting with heart murmur and exercise intolerance who underwent successful CP stent placement. However, severe hypertension with arterial blood pressure increasing to 207/104 mmHg occurred four hours after stent implantation...

A newborn infant with failure to thrive presented for murmur evaluation on day of life three due to a harsh 3/6 murmur. During the evaluation, a retrocardiac fluid filled mass was seen by transthoracic echocardiogram. The infant was also found to have a ventricular septal defect and partial anomalous pulmonary venous return. Eventually, a large hiatal hernia was diagnosed on subsequent imaging. The infant ultimately underwent surgical repair of the hiatal hernia at a tertiary care facility. Hiatal hernias have been noted as incidental extracardiac findings in adults, but no previous literature has documented hiatal hernias as incidental findings in the pediatric population...

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...

CONTEXT AND AIMS: The advent of systematic screening for rheumatic heart disease (RHD) by echocardiography in endemic regions has led to a new entity: borderline RHD. The pathogenicity and natural history of borderline RHD needs to be addressed. The aim of this study was to assess the outcomes of children detected by echocardiography as having borderline RHD. METHODS: Schoolchildren in 4th grade (i.e., aged 9-10years) who were prospectively echo-screened for RHD (2012-2014) in Nouméa, New Caledonia, were asked to participate...

OBJECTIVE: Multiple reports have shown echocardiograms for certain indications are neither cost-effective nor of high diagnostic yield. Given the ease with which tests can be obtained at a tertiary academic children's hospital, our aims were to: (1) determine the diagnostic yield of inpatient studies by in-hospital location; (2) evaluate inpatient echocardiograms to determine indications and level of appropriateness; and (3) evaluate the frequency of cardiology involvement prior to those echocardiograms...

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 found. Similar clinics for children have proven beneficial; the benefit of a HMC in an adult population has been difficult to determine. OBJECTIVES: To review the clinical demographics and echocardiographic information of patients presenting to our HMC and to assess what proportion had significant structural heart disease and determine the common structural abnormalities in this population...

A 23-year-old asymptomatic woman was referred to our hospital for further examination of a systolic ejection murmur with fixed splitting of the second heart sound auscultated at the third left sternal border. Initial echocardiography could not detect the cause. Subsequently performed low-dose computed tomography, however, ruled out the possibility of any congenital heart diseases, but revealed a markedly shortened anteroposterior diameter of the chest, which led us to a diagnosis of straight back syndrome. A vertically oriented "pancake" appearance of the heart, straight vertebral column, and compression of the right ventricular outflow tract were clearly demonstrated on the reconstructed images...

We present a case of 13-year-old female with Turner syndrome (TS), who presented with unexplained lower limbs swelling and ejection systolic murmur at the left second intercostal space. Suspicion of mild aortic coarctation was made by echocardiography. Computed tomography angiography (CTA) showed a complete interruption of the aortic arch (IAA) below the left subclavian artery with persistent left superior vena cava (PLSVC) and absent right SVC, defined as an isolated PLSVC. The patient underwent successful surgical correction after unsuccessful trial of transcatheter stent placement...

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...

: A decline in the incidence of acute rheumatic fever (ARF) in developed countries over the past century can be attributed to the improved public hygiene and to widespread use of antibiotics. ARF seemed to be a rare disease in southern central European country, Slovenia, up to 2010 when we noticed an increase in the number of patients with ARF. In order to assess the current incidence of ARF, we performed a retrospective study of all patients with ARF treated at the University Children's Hospital Ljubljana from January 2008 until the end of December 2014...
