Hydrocephalus represents the pathological elevation of cerebrospinal fluid (CSF) levels as a consequence of various embryological or acquired defects. Although the classic method of treatment is by means of diverting the CSF from the ventricular system towards the peritoneum, there are other sites of diversion that have proven their efficiency through time, in the context of complications related to the more common option of intraperitoneal insertion. The aim of the review is to assess and organize a database of all the types of shunt locations from the oldest shunt attempts until present, using Pubmed and Medline and to underline the particularities related to technique, indications, complications and associated epidemiological background...

Rhabdomyoma is the most common cardiac tumor in infancy and commonly located in the ventricles causing outflow obstruction or arrhythmias. We report a rare pediatric (7 month old) case of a right atrial rhabdomyoma presenting with severe cyanosis and low cardiac output from significant tricuspid inflow obstruction with right to left shunt across a stretched patent foramen ovale. We present an emergency cardiac surgery for right atrial tumor resection, and the management of separating the patient with failing right ventricle from cardiopulmonary bypass using a Glenn shunt, since extracorporeal membrane oxygenation (ECMO) or nitric oxide was not available...

OBJECTIVE: Patients with hydrocephalus secondary to third ventricular colloid cysts may require bilateral external ventricular drain (EVD) placement while awaiting surgery. However, some patients may develop auto-fenestration of the septum pellucidum (AFSP) and only require 1 EVD. We evaluated our experience with bedside iohexol ventriculography and staged EVD placement for patients with obstructive hydrocephalus. METHODS: We retrospectively identified 34 patients treated for third ventricular colloid cysts (2013-2016)...

INTRODUCTION: Ventriculoperitoneal shunts (VPSs) are the mainstay of treatment of hydrocephalus but frequently need revision. We sought to directly compare the impact of laparoscopic versus open peritoneal shunt revision on the need for subsequent VPS revisions in pediatric patients. MATERIALS AND METHODS: A prospectively maintained, externally validated database of pediatric patients who underwent a first peritoneal VPS revision at a single center between 2008 and 2016 was reviewed...

AIMS: Impaired left ventricular diastolic function leading to elevated left atrial pressures, particularly during exertion, is a key driver of symptoms and outcomes in heart failure with preserved ejection fraction (HFpEF). Insertion of an interatrial shunt device (IASD) to reduce left atrial pressure in HFpEF has been shown to be associated with short-term haemodynamic and symptomatic benefit. We aimed to investigate the potential effects of IASD placement on HFpEF survival and heart failure hospitalization (HFH)...

OBJECTIVES: The objectives of this study were to describe the approach to stenting arterial shunts in adult congenital patients with single-ventricle physiology and to assess the medium-term clinical and haemodynamic outcomes following stent insertion. BACKGROUND: Adult patients with single-ventricle physiology and pulmonary blood flow dependent on a surgically placed arterial shunt who did not progress to venous palliation are extremely challenging to manage. Progressive cyanosis secondary to narrowing of the shunt has a marked impact on exercise tolerance and results in intolerable well-being for these patients...

Atrial septal defect (ASD) is the most common form of congenital heart disease. Left-to-right shunting leads to right ventricular (RV) volume overload with excessive pulmonary blood flow. Complications include exercise intolerance, pulmonary vascular disease, RV dysfunction, paradoxical thromboemboli, and atrial arrhythmias. Women with coexisting severe pulmonary hypertension should be counselled against pregnancy due to high incidence of maternal and fetal morbidity and mortality. In the absence of pulmonary hypertension, pregnancy is generally well tolerated in the setting of an ASD...

Alejandro Javier Torres
Atrial septal defect (ASD) is one of the most common congenital cardiac anomalies. ASD can present as an isolated lesion in an otherwise normal heart or in association with other congenital heart conditions. Regardless of the type of ASD, the direction and degree of shunting across the communication is mainly determined by the difference in compliance between the right and left ventricle. Hemodynamics in children is characterized by left-to-right shunting, dilated right heart structures and normal pulmonary artery pressures (PAP)...

Nearly four decades ago, the World Health Organization stated that functional capacity explorations best reflected the impact of a chronic disease on quality of life. Today, cardio-pulmonary exercise test (CPET) is recommended in the follow-up of patients with congenital heart diseases (CHDs). Indeed, the maximum oxygen uptake (VO2max ) and the ventilatory efficiency (VE/VCO2 slope) correlate with both the prognosis and the quality of life in this population. Atrial septal defects (ASDs) represent the second most frequent CHD and are usually considered as simple CHDs...

Ventricular septal rupture is an uncommon fatal complication of acute myocardial infarction. In rare cases, the rupture can extend into the right ventricular free wall and cause intramyocardial dissection. We describe the case of a patient who developed postinfarction right ventricular free wall dissection with left-to-right shunting and successfully underwent patch repair.

Isolated fourth ventricle syndrome is an uncommon entity due to obstruction of both inlet and outflow foramina. The resulting mass effect from the progressively expanding fourth ventricle may cause symptoms from both cerebellar and brainstem compression. Although a variety of treatment modalities have been advocated for this condition, an in-depth description of placement of a fourth ventriculopleural (VPL) shunt from a single-stage prone approach has not yet been published in the literature. We describe here a case of successful placement of a fourth VPL shunt in a 22-year-old female with a history of a prior posterior fossa pilocytic astrocytoma resection who presented with symptomatic isolated fourth ventricular hydrocephalus...

It is unusual for a moderate-size ventricular septal defect (VSD) to remain asymptomatic and complication-free until the age of 45 years. Similarly, infective endocarditis of anatomically normal pulmonary valve is also rare. Here we report a case in which nature created a protection for VSD, i.e. right ventricular outflow tract (RVOT) obstruction, which led to a complication, i.e. pulmonary valve endocarditis. A 45-year-old sick-looking man presented in medical emergency with fever and progressively increasing breathlessness for the previous 2 weeks...

BACKGROUND: A subset of neonates with single ventricle (SV) physiology has antegrade pulmonary blood flow that is deemed unlikely to be reliable until Glenn. We have used systemic to pulmonary shunt (SPS) with pulmonary artery banding (PAB) to optimize pulmonary blood flow while maintaining reserve antegrade flow. We hypothesize that this is an effective strategy that can be accomplished without the routine need for cardiopulmonary bypass (CPB). METHODS: We retrospectively reviewed the records of 60 neonates who underwent combined SPS+PAB between 2004-2015...
