A 10 week old female intact Staffordshire terrier was presented with a total of five congenital cardio-thoracic vascular anomalies consisting of a patent ductus arteriosus (PDA) with an aneurysmic dilation, pulmonic stenosis, persistent right aortic arch, aberrant left subclavian artery and persistent left cranial vena cava. These abnormalities were identified with a combination of echocardiogram and computed tomography angiography (CTA). The abnormalities were associated with esophageal entrapment, regurgitation, and volume overload of the left heart with left atrial and ventricular enlargement...

Interventional cardiac catheterization has a major place in the management of congenital heart disease. Since the Rashkind atrioseptostomy in mid-1960s, many techniques have been developed. For some, it is necessary to close a cardiac or extracardiac shunt using occluder (double disc system, plug, coil…): closure of atrial septal defect, ventricular septal defect or patent arterial duct. For others, it is necessary to treat a valvular or vascular stenosis using a balloon catheter: dilatation of the pulmonary or the aortic valve, dilatation of aortic coarctation...

Two children with congenital heart disease status-post surgical correction presented with prolonged constitutional symptoms, hepatosplenomegaly and pancytopenia. Concern for malignancy prompted bone marrow biopsies that were without evidence thereof. In case #1, echocardiography identified a multilobulated vegetation on the conduit valve. In case #2, transthoracic, transesophageal and intracardiac echocardiography were performed and were without evidence of cardiac vegetations, however pulmonic emboli raised concern for infective endocarditis...

BACKGROUND: Ancient Lake Ohrid, located on the Albania-Macedonia border, is the most biodiverse freshwater lake in Europe. However, the processes that gave rise to its extraordinary endemic biodiversity, particularly in the species-rich gastropods, are still poorly understood. A suitable model taxon to study speciation processes in Lake Ohrid is the pulmonate snail genus Acroloxus, which comprises two morphologically distinct and ecologically (vertically) separated endemic species. Using a multilocus phylogenetic framework of Acroloxus limpets from the Euro-Mediterranean subregion, together with molecular-clock and phylogeographic analyses of Ohrid taxa, we aimed to infer their geographic origin and the timing of colonization as well as the role of geography and ecology in intra-lacustrine diversification...

BACKGROUND: Schistosomiasis remains one of the most common endemic parasitic diseases affecting over 230 million people worlwide. Schistosoma mansoni is the main species causing intestinal and hepatic schistosomiasis and the fresh water pulmonate snails of the genus Biomphalaria are best known for their role as intermediate hosts of the parasite. The development of new molecular monitoring assays for large-scale screening of snails from transmission sites to detect the presence of schistosomes is an important point to consider for snail control interventions related to schistosomiasis elimination...

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...

Natural killer cells (NK cells) and natural killer T cells (NKT cells) play a role in anti-infection, anti-tumor, transplantation immunity, and autoimmune regulation. However, the role of NK and NKT cells during Schistosoma japonicum (S. japonicum) infection has not been widely reported, especially regarding lung infections. The aim of this study was to research the NK and NKT cell response to S. japonicum infection in the lungs of mice. Using immunofluorescent histological analysis, NK and NKT cells were found near pulmonary granulomas...

BACKGROUND: A pattern of ingressive substitutions for word-final sibilants can be identified in a small number of cases in child speech disorder, with growing evidence suggesting it is a phonological difficulty, despite the unusual surface form. Phonological difficulty implies a problem with the cognitive process of organizing speech into sound contrasts. AIMS: To evaluate phonological therapy approaches in the remediation of non-pulmonic speech errors. Thus, adding to evidence concerning the nature of ingressive substitutions and their remediation whilst highlighting their occurrence within child speech disorder population for practising and training speech and language therapists...

Major vessel injury during right ventricular outflow tract ablation is not something widely recognized, and routine evaluation of the left anterior descending artery (LAD) location in relation to the septal right ventricle is not routinely performed. In the present article we report a case of acute LAD occlusion after RVOT ablation and then illustrate the intimately close relationship of the left anterior descending artery to the anterior septal site of the RVOT (∼ 2-3 cm under the pulmonic valve), using a combination of intracardiac echocardiography and 3D electroanatomical mapping (EAM) recorded during a second case, in order to specifically point to the area at risk...

BACKGROUND: To determine reference echocardiographic values in a normal population and assess their correlation with body mass index (BMI) and body surface area. METHODS: An expert cardiologist performed two-dimensional echocardiography with triplicate right ventricle (RV) size measurements in 80 subjects with normal heart condition. Results were correlated with anthropometric data. RESULTS: Base-to-apex length in four-chamber view (RVD3) and above-pulmonic valve in short-axis view in males, as well as mid-RV diameter in standard four-chamber view (RVD), basal RV diameter, and mid RV diameter in RV-focused four-chamber view in females, were significantly correlated with BMI...

Isolated pulmonary valve endocarditis in intravenous drug users is a rarely reported phenomenon. We present the case of a 25-year-old male with history of intravenous drug use who presented with respiratory symptoms after failing outpatient treatment for community-acquired pneumonia. Further investigations identified multiple lung lesions with early cavitation, concerning for septic pulmonary embolism on computerized tomography scan, positive blood cultures with methicillin-susceptible staphylococcus aureus, and isolated vegetation of the pulmonic valve on transthoracic echocardiography...

BACKGROUND: The underlying molecular aetiology of congenital heart defects is largely unknown. The aim of this study was to explore the genetic basis of non-syndromic severe congenital valve malformations in two unrelated families. METHODS: Whole-exome analysis was used to identify the mutations in five patients who suffered from severe valvular malformations involving the pulmonic, tricuspid and mitral valves. The significance of the findings was assessed by studying sporulation of yeast carrying a homologous Phospholipase D (PLD1) mutation, in situ hybridisation in chick embryo and echocardiography and histological examination of hearts of PLD1 knockout mice...

Digenetic trematodes have complex life cycles involving multiple hosts and free-living larval stages. Some species have 2 lar-val stages that infect snails, with miracidia and cercariae using these molluscs as first and second intermediate hosts, respec-tively. Although both larval stages may infect the same snail species, this is accomplished using different chemical cues and may be influenced by different biotic and abiotic factors. Significant differences in the infection patterns of these parasitic stages regarding host size and density were observed in 2 separate field studies...

INTRODUCTION: RASopathies include disorders generally characterized by developmental delay, specific heart defects, short stature, cardiac hypertrophy, and facial dysmorphisms. Next-generation sequencing (NGS)-based panels have widespread acceptance as a diagnostic tool for RASopathies. MATERIALS AND METHODS: The first 126 patients evaluated by clinical examination and the NGS RASopathy panel at the Children's Hospital of Philadelphia were enrolled. We calculated diagnosis rate, correlated reported clinical findings with positive or negative test results, and identified final molecular diagnoses in 28/96 patients who tested negative for RASopathies...

REVIEW
Aneeta Bhatia
The tricuspid is the lost valve and the pulmonary being the most anterior, is not visualized well on TEE; The Pulmonary valve is a semilunar valve that separates the right ventricle from the pulmonary artery. It is situated anterior and superior to the aortic valve, almost at right angle to the aortic valve and parallel to the beam of the ultrasound.

We present a 62-year-old lady admitted in our hospital with two episodes of acute ischemic stroke about 2 weeks apart. She was evaluated for acute ischemic stroke and was thrombolysed for recent stroke in right MCA territory first time. On further evaluation, she was found to have a RVOT mass. A transthoracic and transesophageal echocardiogram revealed a PFO and a large, 5.1cm×2.3cm, ovoid, well circumscribed, echogenic mass in the right ventricle outflow tract attached by small pedicle to the ventricular side of anterior tricuspid leaflet, partly obstructing the right ventricular outflow tract and protruding through the pulmonic valve during systole...
