BACKGROUND: Reconstruction of the right ventricular outflow tract with a conduit is an established surgical procedure in congenital heart disease and reinterventions are common. OBJECTIVE: An increasing number of patients have a conduit, but there are few population-based studies of long-term outcomes after conduit surgery, reoperations, and transcatheter pulmonary valve replacement. METHODS: In April 2015, all adult patients with a conduit were identified in the Swedish National Registry for Congenital Heart Disease (SWEDCON)...

Prenatal exposure to toxic trace elements, including heavy metals, is an important public health concern. Few studies have assessed if individual and multiple trace elements simultaneously affect cardiac development. The current study evaluated the association between maternal blood lead (Pb), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), and selenium (Se) levels and congenital heart defects (CHDs) in offspring. This hospital-based case-control study included 112 case and 107 control infants. Maternal peripheral blood draw was made during gestational weeks 17-40 and used to determine trace element levels by inductively coupled plasma mass spectrometry...

The lateral habenula (LHb) has an important role in the behavioural response to salient, usually aversive, events. We previously demonstrated that activation of neurons in the LHb increases brown adipose tissue (BAT) thermogenesis and constricts the cutaneous vascular bed, indicating that the LHb contributes to the central control of sympathetic outflow to thermoregulatory effector organs. We have now investigated whether the LHb mediates BAT thermogenesis elicited by emotional stress, and whether the LHb modulates thermoregulatory sympathetic outflow via the rostral medullary raphé, a key integrative lower brainstem sympathetic control centre...

The nitrogen (N) cycling dynamics of four stormwater basins, two often saturated sites ("Wet Basins") and two quick draining sites ("Dry Basins"), were monitored over a ~1-year period. This study paired stormwater and greenhouse gas monitoring with microbial analyses to elucidate the mechanisms controlling N treatment. Annual dissolved inorganic N (DIN) mass reductions (inflow minus outflow) were greater in the Dry Basin than in the Wet Basin, 2.16 vs. 0.75 g N m-2 yr-1, respectively. The Dry Basin infiltrated a much larger volume of water and thus had greater DIN mass reductions, even though incoming and outgoing DIN concentrations were statistically the same for both sites...

The activity of pre-sympathetic neurons is under respiratory modulation and changes in the central respiratory network may impact on the baseline sympathetic activity and mean arterial pressure (MAP). It is well known that after baroreceptor afferents removal (sino-aortic denervation, SAD), rats present an unexpected normal levels of MAP. We hypothesized that changes in the respiratory pattern and in the respiratory modulation of the sympathetic activity contribute to keep the sympathetic outflow in a normal range of variation in absence of arterial baroreceptors in rats...

Apical hypertrophic cardiomyopathy is a rare form of hypertrophic cardiomyopathy that involves thickening of the distal portion of the left ventricular wall. Most commonly seen in the Japan, with a prevalence rate of about 15% of all HCM patient, its incidence in the USA is approximately 3% of HCM cases. We report a case of a 46-year-old woman with history of hypertension who presented to emergency department with worsening dyspnea and orthopnea with features of left ventricular hypertrophy (LVH) and diffuse large T-wave inversions in the lateral leads on a 12-lead ECG...

BACKGROUND: We recently reported a novel observation that many patients with equal resting supine right ventricular(RV) and pulmonary artery(PA) systolic pressures develop an RV outflow tract(RVOT) pressure gradient during upright exercise. The current work details the characteristics of patients who develop such an RVOT gradient. METHODS: We studied 294 patients (59.7±15.5 years-old, 49% male) referred for clinical invasive cardiopulmonary exercise testing, who did not have a resting RVOT pressure gradient defined by the simultaneously measured peak-to-peak difference between RV and PA systolic pressures...

Evidence shows altered somatosensory temporal discrimination threshold (STDT) in Parkinson's disease in comparison to normal subjects. In healthy subjects, movement execution modulates STDT values through mechanisms of sensory gating. We investigated whether STDT modulation during movement execution in patients with Parkinson's disease differs from that in healthy subjects. In 24 patients with Parkinson's disease and 20 healthy subjects, we tested STDT at baseline and during index finger abductions (at movement onset "0", 100, and 200 ms thereafter)...

BACKGROUND: Spinal dural arteriovenous fistula (DAVF) is a rare disease and multiple concurrent lesions are extremely rare. Such multiple spinal DAVFs have similar outflow routes at neighboring levels. However, there have been no reported cases of remote lesions of multiple spinal DAVFs. The authors herein report a case of double synchronous cervical and sacral DAVFs. CASE DESCRIPTION: A 56-year-old man with no prior history of disease presented with progressive myelopathy, and spinal magnetic resonance imaging (MRI) showed extensive edema of the spinal cord from the conus to T7...

OBJECTIVES: The main reason for aortic repair failures is recurrent annular dilatation. The fibrous portion of left ventricular outflow tract dilates. A novel device was designed to tackle this problem. METHODS: The device consists of an internal ring applied at the aortic annulus plus an external flexible band at the level of the aortic root. The internal ring has a semi-rigid portion (40%, placed at ventriculo-arterial junction) and a flexible portion to allow it to conform along the curves of the non-coronary/right coronary leaflet and right coronary/left coronary leaflet commissures...

Ebstein's anomaly in combination with tetralogy of Fallot (TOF) is rare. We report a male infant with these combined anomalies who presented with severe cyanosis, heart failure, and respiratory distress after birth. Biventricular repair was successfully performed with 1-stage correction of his ventricular septal defect (VSD), right ventricular outflow tract (RVOT) obstruction, and tricuspid regurgitation. The downward displaced tricuspid valve was also restored to the normal annulus position. The infant recovered well...

Transcatheter pulmonary valve implantation is established as a valuable option to reconstruct failing right ventricular outflow tract function. Percutaneous tricuspid valve-in-valve or valve-in-ring reconstruction is even applied with increasing acceptance. A 46-year-old woman with a diagnosis of carcinoid-dependent right heart failure underwent surgical bioprosthetic tricuspid and pulmonary valve replacement. Almost 1 year later, she presented again with markedly dilatated and reduced right heart function caused by degeneration of both biologic valves...

Left atrioventricular (AV) valve regurgitation is the most common complication after a atrioventricular canal defect (AVCD) repair. Despite what appears to be a less complex repair, patients with partial and transitional AV canal have higher reoperation rates for left AV valve regurgitation and left ventricular outflow tract (LVOT) obstruction. Retraction of bridging leaflets with secondary attachments to the septal crest commonly produces increased tension and flattening of the medial left AV valve leaflet and LVOT obstruction after cleft closure...

Background Malfunction of the peritoneal dialysis catheter is frequently caused by dislocation. The diagnostic approach is classically based on abdomen X-ray together with detailed case history and physical examination. Despite being rarely applied in clinical practice to evaluate catheter misplacement, ultrasound is a noninvasive, radiation-free technique that is potentially useful also to explore reasons for catheter malfunction. Consequently, we aimed to evaluate the diagnostic accuracy of ultrasound to identify peritoneal catheter misplacement...

Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (MAIVF-P) is one of the rare complications of endocarditis or, more rarely, of surgical trauma. This condition is characterized by a pseudoaneurysm in the intra-annular area between the mitral valve and the aortic valve communicating with the outflow tract of the left ventricle, between the coronary or noncoronary left aortic valve and the front flap of the mitral valve. Nowadays, surgery is recommended to avoid further growth and complications. We hereby describe the case of a patient with MAIVF-P as a consequence of a surgical trauma and early appearance of MAIVF-P...
