As a ubiquitous signaling molecule, nitric oxide (NO) exerts various important effects on the cardiovascular system and is involved in the regulation of vascular tone and myocardial metabolism in vertebrates. Lungfishes are closely related to tetrapods and provide an interesting possibility to understand the transition from water to land. Lungfishes are endowed with both systemic and pulmonary circulations, and their incompletely divided ventricle allows for blood to bypass either circuit. Lungfishes inhabit ephemeral waterbodies that may enforce prolonged aestivation during drought, throughout which nitric oxide synthase (NOS) expression is upregulated...

Isolated Unilateral hypoplasia or agenesis of a branch of pulmonary artery is very rare. It is usually seen associated with congenital heart diseases such as tetralogy of Fallot, atrial septal defect, coarctation of the aorta, right aortic arch, truncus arteriosus, patent ductus arteriosus and pulmonary atresia. It occurs as a result of lack of embryological development of either the left or right sixth aortic arch and has been found to present itself with various clinical manifestations as during childhood it presents as contralateral pulmonary hypertension and in adults as haemoptysis...

OBJECTIVE: Closing patent ductus arteriosus (PDA) is a widely accepted approach in the management of very low birth weight (VLBW) infants. Our objective is to test the hypothesis that conservative management (no treatment) of PDA will not affect survival without chronic lung diseases (CLD). STUDY DESIGN: This retrospective study utilizes a prospectively collected database to compare two cohorts of VLBW infants. Infants in the first group (2001 to 2009) had their PDA treated with pharmacological and if necessary with surgical ligation...

The diagnosis of patent ductus arteriosus (PDA) with Eisenmenger syndrome is difficult. We report a case of 35-year-old male who came to our outpatient department (OPD) for evaluation of repeated hemoptysis and dyspnea on exertion. He had already completed two courses of ATT. On examination, grade 3 ejection systolic murmur was audible over precordium. Transthoracic echocardiography (TTE) showed enlargement of right atrium (RA) and right ventricular (RV) with severe tricuspid regurgitation (TR). On agitated saline contrast injection, agitated saline was seen in pulmonary artery followed by filling of abdominal aorta without filling of ascending aorta, thus confirming the diagnosis of right to left shunt with PDA...

Objective The objective of this study was to assess the result of intravenous pentoxifylline as an adjunct to antibiotic therapy on mortality and morbidity in very low birth weight (VLBW) preterm neonates with nosocomial sepsis. Methods For the 18 VLBW preterm neonates, as an adjunct therapy to antibiotics regimens, pentoxifylline (5 mg/kg/h for 6 hours) was administered to premature infants with sepsis on 3 successive days. Clinical and laboratory parameters were recorded before and after treatment. Results Following pentoxifylline therapy, the immature-to-total neutrophil ratio and C-reactive protein (CRP) levels were significantly decreased, while the blood pH and base excess were significantly increased (p < 0...

Pregnancy is typically contraindicated in Eisenmenger syndrome because of its association with excessively high maternal and fetal morbidity and mortality. We report on our novel approach to successfully managing a 29 year-old pregnant woman with an unrepaired patent ductus arteriosus (PDA) with Eisenmenger syndrome through delivery and recovery. Venovenous ECMO was utilized during induction of labor to stabilize maternal hemodynamics and optimize fetal oxygenation by creating an oxygenated right-to-left shunt through the PDA...

OBJECTIVES: In the recent TRUFFLE study it appeared that, in pregnancies complicated by fetal growth restriction (FGR) between 26 and 32 weeks, monitoring of the ductus venosus (DV) combined with computerised cardiotocography (cCTG) as a trigger for delivery, increased the chance of infant survival without neurological impairment. However, concerns in interpretation were raised as DV monitoring appeared associated with a non-significant increase in fetal death, and part of the infants were delivered after 32 weeks, after which the study protocol was no longer applied...

BACKGROUND: Perforation of pulmonary valve using radiofrequency ablation in pulmonary atresia with intact ventricular septum (PA IVS) is a treatment of choice. However, significant cost of the equipment limits its utility, especially in the developing economies. OBJECTIVE: To assess the feasibility, safety, and efficacy of perforation of pulmonary valve using chronic total occlusion (CTO) wires in patients with PA IVS as an alternative to radiofrequency ablation...

The management of pulmonary atresia with a ventricular septal defect (PA/VSD) depends on the anatomy of the pulmonary artery or on the surgical strategy used at individual institutions. In our institution, we adopted a right ventricle-to-pulmonary artery (RV-PA) shunt in 2011 as a palliative procedure for PA/VSD to overcome the disadvantages of a Blalock-Taussig shunt. We evaluated the results of the RV-PA shunt as initial palliative surgery for PA/VSD. Thirteen patients with ductus-dependent PA/VSD from August 2011 to August 2015 were enrolled...

Ménière's disease is an inner ear disorder characterized by vertigo attacks, fluctuating and progressive hearing loss, tinnitus, and aural fullness in the affected ear. The pathophysiology of Ménière's disease remains elusive. Theories so far are anatomical variation in the size or position of the endolymphatic sac and duct, viral inflammation or autoimmune involvement of the sac, or a genetically determined abnormality of endolymph control. Animal studies on blocking the ductus reuniens and endolymphatic duct have produced hydrops in the cochlea, saccule, and utricle...

BACKGROUND: Aortic arch abnormalities represent 5% to 8% of all congenital heart disease. Measurements of the aortic arch dimensions on two-dimensional echocardiographic images remain of critical importance in the diagnosis of aortic arch pathology. To define aortic hypoplasia or coarctation, measured dimensions must be compared with normal values. Normal values have been described for children of all ages in earlier studies. However, normative data for premature infants are not yet available...

Hypotension is a common problem in neonates with complex underlying pathophysiology. Although treatment of low blood pressure is common, clinicians must use all available information to target neonates with compromised perfusion. Pharmacotherapy should be tailored to the specific physiologic perturbations of the individual neonate. Dopamine is the most commonly utilized agent and may be the most appropriate agent for septic shock with low diastolic blood pressure. However, alternative therapies should be considered for other etiologies of hypotension, including milrinone and vasopressin for persistent pulmonary hypertension of the newborn and dobutamine for patent ductus arteriosus...
