Despite the increasing use of percutaenous valves, little is known about valve performance after external chest compression. We report a case of a compressed pulmonary Edwards Sapien® XT valve after resuscitation. With the patient on ECMO, successful redilatation was performed with unimpaired postprocedural valve function. We aim to increase the awareness for valve distortion after external chest compression with increasing numbers of transcatheter valvulations. We suggest that immediate re-evaluation of the implanted device via biplane fluoroscopy is mandatory after resuscitation in such cases...

En 1967, Ashbaugh et al. publicaron en Lancet la descripción de una nueva entidad para la que acuñaron el nombre "síndrome de distress respiratorio del adulto". En ese artículo describieron minuciosamente a 12 enfermos que presentaban insuficiencia respiratoria, con infiltración pulmonar bilateral e hipoxemia resistente a oxigenoterapia. Para su manejo se hizo énfasis en la importancia de la intubación y la ventilación mecánica con presión positiva al final de la espiración. A 50 años de la publicación se han logrado grandes avances en el conocimiento de esta enfermedad, lo que ha influido en el manejo y supervivencia de los pacientes...

The placenta is a complex organ that influences prenatal growth and development, and through fetal programming impacts postnatal health and well-being lifelong. Little information exists on placental pathology in the presence of congenital heart disease (CHD). Our objective is to characterize the placenta in CHD and investigate for distinctions based on type of malformation present. Placental pathology from singleton neonates prenatally diagnosed and delivered at > 37 weeks gestation was analyzed. Placental findings of absolute weight, placental weight-to-newborn birth weight ratio, chorangiosis, villus maturity, thrombosis, and infarction were recorded and analyzed based on four physiological categories of CHD: (1) single ventricle-aortic obstruction, (2) single ventricle-pulmonic obstruction, (3) two-ventricle anomalies, and (4) transposition of the great arteries (TGA)...

BACKGROUND: Patients with congenital cardiovascular disease involving the right ventricular outflow tract and with prosthetic valves in the heart are at high risk for developing infective endocarditis (IE). Recently, there has been concern about relatively high rates of IE after percutaneous pulmonary valve implantation (PPVI). Although there are factors specific to percutaneous valves that could plausibly contribute to the risk of IE, including procedural steps prior to implantation such as crimping the valved stent or mechanical forces during dilation, little is known about actual risk factors for this complication...

In cardiac magnetic resonance imaging (CMR), accurate flow measurements rely on perpendicular plane-alignment with flow direction. For 2D phase contrast (PC) cardiac magnetic resonance measurements, planes have to be defined during the examination of the heart, which is time consuming and error-prone. Collection of flow information of the entire volume of the heart by a 4D flow CMR postpones plane alignment to post-processing. Sampling of such a large amount of data requires acceleration of data acquisition with techniques such as SENSitivity Encoding (k-t SENSE) or Broad-use Linear Acquisition Speed-up Technique (k-t BLAST)...

Freshwater pulmonate snails are sensitive to trace metals, but to date, the sensitivity of estuarine pulmonate snails to these important environmental toxicants is undescribed. Using the estuarine mud snail Amphibola crenata, effects of a 48-h exposure to waterborne cadmium (Cd) were investigated. The 48-h median lethal concentration (LC50 ) was 50.4 mg L-1 , a value higher than that previously reported for any gastropod mollusc. Cadmium levels in the tissues of mud snails were highest in the viscera (digestive gland and gonad), with the foot muscle and remaining tissue compartment (kidney, mantle, remaining digestive tissues and heart) displaying significantly lower concentrations...

Meningiomas are typically benign solitary intracranial tumors. Atypical (World Health Organization [WHO] grade II) or malignant/anaplastic (WHO grade III) meningiomas are seldom, and distant metastases occur only in rare exceptions. We present a case of a 54-year-old male patient with atypical (WHO grade II) meningioma who underwent 1 cycle of peptide receptor radionuclide therapy. Previous imaging studies were confined to the head, but posttherapeutic whole-body Lu-DOTATATE scintigraphy revealed thoracic uptake arising from previously undetected pulmonic meningioma metastases...

Ga-PSMA-11 PET/CT was performed in a 74-year-old man because of biochemical recurrence of prostate cancer following radiation therapy of the prostate gland 24 months earlier. Besides focal nuclide accumulation in the prostate gland suggestive of local recurrence, PET scan revealed no further pathologic uptake. However, CT showed multiple pulmonic nodules suggestive of metastases. Thoracotomy and pathologic examination revealed the nodules to be prostate cancer metastasis. Furthermore, immunohistochemical staining with PSMA antibodies demonstrated a virtual lack of PSMA expression...

Increased blood pressure in the pulmonary artery is referred to as pulmonary hypertension and often is linked to loud pulmonic valve closures. For the purpose of this paper, it was hypothesized that pulmonary circulation vibrations will create sounds similar to sounds created by vocal cords during speech and that subjects with pulmonary artery hypertension (PAH) could have unique sound signatures across four auscultatory sites. Using a digital stethoscope, heart sounds were recorded at the cardiac apex, 2nd left intercostal space (2LICS), 2nd right intercostal space (2RICS), and 4th left intercostal space (4LICS) undergoing simultaneous cardiac catheterization...

BACKGROUND AND PURPOSE: The diverse causes of right-sided heart failure (RHF) include, among others, primary cardiomyopathies with right ventricular (RV) involvement, RV ischemia and infarction, volume loading caused by cardiac lesions associated with congenital heart disease and valvular pathologies, and pressure loading resulting from pulmonic stenosis or pulmonary hypertension from a variety of causes, including left-sided heart disease. Progressive RV dysfunction in these disease states is associated with increased morbidity and mortality...

OBJECTIVE: Rheumatic heart disease (RHD) prevails as a major public health problem in sub-Saharan Africa. In Cameroon, reports on RHD have been so far limited to a few cities. We sought to describe the demographic, clinical and echocardiographic features of rheumatic heart disease in the Buea Regional Hospital, South West region of Cameroon. Echocardiography reports between June 2016 and June 2017 were reviewed. The diagnosis of RHD was based on the World Heart Federation Criteria for the diagnosis of RHD...

Evaluation of antiphospholipid antibodies (aPL) and correlation with heart valve abnormalities among patients with systemic lupus erythematosus (SLE). Nested case-control study was conducted with 70 patients with SLE selected from a longitudinal database based on levels of aPL and presence or absence of valve disease by echocardiogram. Valvular abnormalities observed were regurgitation (52), other (14), artificial valves (4), stenosis (2), thickening (2) and no Libman-Sacks endocarditis (0). The mitral valve was the most commonly affected (30 abnormalities), followed by the tricuspid (20 abnormalities)...

Despite the utility of gastropod models for the study of evolutionary processes of great generality and importance, their effective population size has rarely been estimated in the field. Here, we report allele frequency variance at three allozyme-encoding loci monitored over 7 years in a population of the invasive freshwater pulmonate snail Physa acuta (Draparnaud 1805), estimating effective population size with both single-sample and two-sample approaches. Estimated N e declined from effectively infinite in 2009 to approximately 40-50 in 2012 and then rose back to infinity in 2015, corresponding to a striking fluctuation in the apparent census size of the population...

The normal aortic valve is a sophisticated and dynamic structure whose equal replacement has not yet been actualized by modern technology. The use of the pulmonary autograft as a substitute for a diseased aortic valve (the Ross procedure) has been in practice for several decades in many types of patient. In the adult, it has not been adopted widely due to concerns about its technical challenge, complex perioperative care, the development of pulmonic valve disease, and concerns about long-term dilatation of the neo-aortic root, among others...

This report illustrates a case of a 42-year-old male with a history of intravenous drug abuse who presented with septic shock. Diagnostic studies, including a transthoracic echocardiogram, chest computed tomography angiography, transesophageal echocardiogram, and blood cultures ultimately revealed Serratia marcescens pulmonic valve infective endocarditis that was treated with intravenous antibiotics. In addition to the rare form of endocarditis and bacterium involved, this case brings into awareness the dynamic nature of the hospital course that requires vigilance in responding to hypotensive episodes for consideration of pulmonary embolism...

The diet of organisms generally provides a sufficient supply of energy and building materials for healthy growth and development, but should also contain essential nutrients. Species differ in their exogenous requirements, but it is not clear why some species are able to synthesize essential nutrients, while others are not. The unsaturated fatty acid, linoleic acid (LA; 18:2n-6) plays an important role in functions such as cell physiology, immunity, and reproduction, and is an essential nutrient in diverse organisms...

Double outlet right ventricle with subpulmonic ventricular septal defect is a very rare form of congenital heart disease. Surgical correction involves closure of the ventricular septal defect with baffling of blood flow from the left ventricle to the pulmonic valve and arterial switch of the usually side-by-side great arteries. In this tutorial, we present our surgical technique for single-stage repair of this complex anomaly.
