Systemic-to-pulmonary artery shunt placement is an established palliative procedure for congenital heart disease, but it is associated with high morbidity and mortality. Data of all patients with biventricular circulation who underwent systemic-to-pulmonary artery shunt implantation between 2000 and 2016 were reviewed. Endpoints of the study were shunt failure and shunt-related mortality. Shunt failure was defined as any shunt dysfunction requiring intervention or reoperation. Shunt-related mortality was defined as death due to shunt dysfunction...

Background: The dynamic behavior of the aortic sinuses has an important function in the specific characteristics of coronary blood flow. Several publications have confirmed suboptimal myocardial perfusion after the Norwood procedure. Our study was undertaken to confirm four hypotheses. First, we hypothesized that there is more resistance to coronary flow due to coronary attachments to hypoplastic aortic root and sinuses. Also, as the amalgamation of the ascending aorta with the pulmonary artery occurs above the aortic root, the coronary blood flow is not fully in antegrade pattern...

Ventricular dysfunction affects survival in patients with single right ventricle (RV), and remains one of the primary indications for heart transplantation. Since it is challenging to predict the capacity of patients with ventricular dysfunction to proceed to the stage II procedure, we sought to identify factors that would be associated with death or heart transplantation without achieving stage II for single RV patients with ventricular dysfunction after Norwood procedure. The Single Ventricle Reconstruction (SVR) trial public-use database was used...

Neonatal primary repair of tetralogy of Fallot (TOF) with absent pulmonary valve (APV) syndrome is associated with high mortality rates. Our plan involves a staged repair that avoids one-stage intracardiac repair (ICR), with a first palliation that closes the main pulmonary orifice using an expanded polytetrafluoroethylene (ePTFE) patch, pulmonary arterioplication, and an adjustable Blalock-Taussig (BT) shunt. This strategy was used for a neonatal case with TOF/APV syndrome with hypoplastic left ventricle (LV)...

Premature infants are at high risk for developing bronchopulmonary dysplasia (BPD), characterized by chronic inflammation and inhibition of lung development, which we have recently identified as being modulated by microRNAs (miRNAs) and alterations in the airway microbiome. Exosomes and exosomal miRNAs may regulate cell differentiation and tissue and organ development. We discovered that tracheal aspirates from infants with severe BPD had increased numbers of, but smaller, exosomes compared with term controls...

Percutaneous therapies for congenital heart disease have been evolving rapidly despite limited investment from industry. The Melody transcatheter pulmonary valve (Medtronic, Inc, Minneapolis, MN USA) replacement therapy represents an important advancement in this arena. It has been approved in the United States for use in the pulmonary position, on a Humanitarian Device Exemption status. Off-label use of the Melody transcatheter pulmonary valve has extended to the mitral, pulmonary, and aortic valves, especially in previously implanted valves with prosthetic valve degeneration...

Individuals with Social Anxiety Disorder (SAD) have difficulty engaging in social situations because their actions are predicated on minimizing the subjectively biased high potential for rejection. That is, individuals with SAD frequently perceive social situations as challenging, and their performance as subpar. Yet when individuals perceive themselves as succeeding in challenging situations, they typically report these situations as enjoyable and rewarding. This subjective experience of succeeding in a challenging situation has been studied as flow (Csikszentmihalyi, 1975; 2000)...

OBJECTIVE: Eating disorders are associated with multiple medical complications. We report contemporary medical data, for newly admitted adult inpatient and residential level of care patients. METHOD: Medical records of a transdiagnostic sample of 1,026 patients, with eating disorders, were retrospectively reviewed for the presence of a broad array of medical complications at time of admission. The prevalence of physiologically relevant medical complications was assessed across major eating disorder categories...

BACKGROUND: Stage 1 palliation of hypoplastic left heart syndrome (HLHS) involves the Norwood procedure combined with a modified Blalock-Taussig shunt (mBTS) or right ventricle to pulmonary artery shunt (RVPAS). Short-term survival has been described previously, whereas longer-term outcomes remain a subject of debate. This meta-analysis aimed to describe the short and long-term survival outcomes of these two shunts, and explore factors that might influence survival. METHODS: Medline, Cochrane Libraries and EMBASE were systematically searched, and 32 studies were included for statistical synthesis, comprising 1348 mBTS and 1258 RVPAS patients...

BACKGROUND:  Systemic-to-pulmonary artery shunt placement is an established palliative procedure for congenital heart disease. Although it is thought to be a simple operation, it is associated with significant morbidity and mortality. METHODS:  Data for all neonates who underwent surgery for a systemic-to-pulmonary artery shunt between 2000 and 2016 were reviewed. The study endpoints were shunt failure and shunt-related mortality. Shunt failure was defined as a shunt dysfunction because of thrombosis or stenosis requiring intervention or reoperation; shunt mortality was defined as death because of a shunt dysfunction...

OBJECTIVE: Transfontanelle ultrasound is a noninvasive method for assessing cerebral blood flow in neonates and infants. The authors applied this technique as a point-of-care tool, before and after modified Blalock-Taussig shunt procedure, to evaluate cerebral perfusion. DESIGN: Retrospective, observational study. SETTING: Tertiary care children's hospital. PARTICIPANTS: Ten infants undergoing modified Blalock-Taussig shunt procedure...

BACKGROUND: Endotoxemia in pediatric cardiac surgical patients is poorly understood. The endotoxin activity assay (EAA) levels were examined in neonates undergoing cardiac surgery in order to assess their reference levels and their association with other pre-, intra-, and postoperative risk factors for gut hypoperfusion. We finally observed if refeeding was associated with modification of endotoxin levels. METHODS: In a prospective cohort study, neonates undergoing surgery for correction or palliation were enrolled...

We report a newborn female baby who presented at 6 hours of age with cyanosis without any signs of respiratory distress. Cardiovascular and systemic examination was unremarkable apart from cyanosis (saturation 75%). An echocardiogram showed multiple echogenic and homogeneous masses in the interventricular septum, one of which was big and protruding through the tricuspid valve causing right ventricular inflow obstruction. There was a small atrial septal defect (ASD) shunting right to left and patent ductus arteriosus (PDA) shunting left to right...

BACKGROUND: Staged palliative surgery markedly shifts the balance of volume load on a single ventricle and pulmonary vascular bed. Blalock-Taussig shunt necessitates a single ventricle eject blood to both the systemic and pulmonary circulation. On the contrary, bidirectional cavopulmonary shunt release the single ventricle from pulmonary circulation.

PURPOSE/BACKGROUND: It is unclear whether increasing the dose of varenicline beyond the standard dose of 2 mg/d would improve smoking abstinence. METHODS: We examined the effect of 3 mg/d of varenicline on smoking abstinence among smokers who had reduced their smoking by 50% or more in response to 2 mg/d for at least 6 weeks but had not quit smoking. Of 2833 patients treated with varenicline, dosage of a subset of 73 smokers was increased to 3 mg/d after 6 weeks...

OBJECTIVE: This historical perspective documents the role that John L. Cameron played in advancing hepatobiliary research, education, and surgery at Johns Hopkins in the 1970s, 1980s, and 1990s. SUMMARY OF BACKGROUND DATA: Dating back to William S. Halsted in the 19th century, leaders of the Department of Surgery at Johns Hopkins have been interested in hepatobiliary disease and surgery. John L. Cameron had broad hepato-pancreato-biliary (HPB) interests when he completed his surgical training...
