Guidelines for the diagnosis and treatment of hypertension were published by the American Heart Association (AHA) in 2017. The prevalence of hypertension in adults with congenital heart disease (ACHD) under these guidelines has yet to be characterized. We sought to assess the prevalence, impact, and provider response to hypertension under current guidelines. Data were obtained retrospectively from records of routine clinic visits over a 10 year period. Potential hypertension-related adverse outcomes including stroke, myocardial infarction, surgical intervention for aortic aneurysm, aortic dissection, atrial fibrillation or flutter, cardiac transplantation and death were recorded. The 1070 patients who met inclusion criteria had a mean age of 30.8 ± 10.0 years. The prevalence of hypertension under the 2017 guidelines was 46.6%. Multivariate modeling identified cyanosis, male gender, older age, and overweight/obesity as independent risk factors for hypertension. Guideline-directed management of hypertension in ACHD patients occurred more frequently in ACHD and adult cardiology clinics than in pediatric cardiology clinics (44.1% and 45.1% vs. 24.0%, p < 0.01, respectively). Adverse outcomes were reported in 217 (20%) patients, the most prevalent of which was atrial fibrillation or flutter (11%). Multivariable modelling for any adverse outcome identified older age, hypertension, cyanosis, greater complexity ACHD, and obesity as risk factors. Modifiable risk factors for atherosclerotic cardiovascular disease are common and often under addressed in the ACHD population.

The data are insufficient to support standardized treatment of all patients with frostbite with thrombolytic therapy. The following guidelines, however, should be applied to all patients with cyanosis persisting proximal to the distal phalanx (Grade 3 or 4 frostbite injury) and demonstrated loss of perfusion at or proximal to the middle phalanx immediately after rewarming.

Five years after the first edition, we have revised and updated the guidelines, re-examining the queries and relative recommendations, expanding the issues addressed with the introduction of a new entity, recently proposed by the American Academy of Pediatrics: BRUE, an acronym for Brief Resolved Unexplained Events. In this manuscript we will use the term BRUE only to refer to mild, idiopathic cases rather than simply replace the acronym ALTE per se.In our guidelines the acronym ALTE is used for severe cases that are unexplainable after the first and second level examinations.Although the term ALTE can be used to describe the common symptoms at the onset, whenever the aetiology is ascertained, the final diagnosis may be better specified as seizures, gastroesophageal reflux, infection, arrhythmia, etc. Lastly, we have addressed the emerging problem of the so-called Sudden Unexpected Postnatal Collapse (SUPC), that might be considered as a severe ALTE occurring in the first week of life.

The purpose of this review/editorial is to discuss how and when to treat the most common cyanotic congenital heart defects (CHDs); the discussion of acyanotic heart defects was presented in a previous editorial. By and large, the indications and timing of intervention are decided by the severity of the lesion. While some patients with acyanotic CHD may not require surgical or transcatheter intervention because of spontaneous resolution of the defect or mildness of the defect, the majority of cyanotic CHD will require intervention, mostly surgical. Total surgical correction is the treatment of choice for tetralogy of Fallot patients although some patients may need to be palliated initially by performing a modified Blalock-Taussig shunt. For transposition of the great arteries, arterial switch (Jatene) procedure is the treatment of choice, although Rastelli procedure is required for patients who have associated ventricular septal defect (VSD) and pulmonary stenosis (PS). Some of these babies may require Prostaglandin E1 infusion and/or balloon atrial septostomy prior to corrective surgery. In tricuspid atresia patients, most babies require palliation at presentation either with a modified Blalock-Taussig shunt or pulmonary artery banding followed later by staged Fontan (bidirectional Glenn followed later by extracardiac conduit Fontan conversion usually with fenestration). Truncus arteriosus babies are treated by closure of VSD along with right ventricle to pulmonary artery conduit; palliative banding of the pulmonary artery is no longer recommended. Total anomalous pulmonary venous connection babies require anastomosis of the common pulmonary vein with the left atrium at presentation. Other defects should also be addressed by staged correction or complete repair depending upon the anatomy/physiology. Feasibility, safety and effectiveness of treatment of cyanotic CHD with currently available medical, transcatheter and surgical methods are well established and should be performed at an appropriate age in order to prevent damage to cardiovascular structures.

In an effort to increase the safety of sedated procedures, there is a recent trend to increase preprocedure fasting times. However, optimal fasting times have never been established for a sedated echocardiogram. We retrospectively analyzed 334 patients divided into 2 groups. Group 1 (140 patients) had fasting times less than 2 hours, whereas group 2 (184 patients) had fasting times more than 2 hours. When the entire population was considered, there was no difference in efficacy between the 2 groups (P =.08). However, in patients younger than 6 months, group 2 had decreased efficacy compared with group 1 (P =.03). There were no major complications in either group. There was no difference in the rate of minor complications between the 2 groups. Our study concludes that longer fasting times are less efficacious in children younger than 6 months, and do not improve safety.

OBJECTIVE: Recurrent venesection of patients with cyanotic congenital heart disease may be detrimental, with an increased risk of cerebrovascular events and symptomatic iron-deficiency. The aim of this study was to determine the venesection policies as practised in hospitals within a U.K. region and to determine if these policies followed current recommendations.
RESULTS: Fifty-eight consultants (56% response rate) in cardiac specialties completed self-assessment questionnaires regarding the indications for and practice of venesection. Sixty-one percent of those responding were involved directly in the care of patients with cyanotic congenital heart disease and of these clinicians 97% used venesection. Indications for venesection varied, with 51% of those responding using an elevated haemoglobin per se (6.5-21.0 g. dl-1); 78% an elevated haematocrit (0.55-0.75) and 83% symptoms. Desired maintenance haemoglobin and haematocrit levels also varied greatly. Fifty percent of the consultants responding routinely screened their patients for iron deficiency and 23% felt there was no indication for investigating a low mean corpuscular volume. Only 18% of the policies described followed any evidence based principles.
CONCLUSIONS: The practice of venesecting patients with congenital cyanotic heart disease varies greatly. Policies in many hospitals do not reflect the minimal benefits and considerable risks associated with recurrent venesection.

The Neonatal Resuscitation Programme, sponsored by the Canadian Heart and Stroke Foundation and by the American Heart Association, is a structured learning package and workshop for all individuals who provide resuscitation for newborns. The emphasis is on rapid, decisive action using algorithms based on clearly stated criteria. This CME article serves as an introduction to the NRP and discusses some of the new guidelines regarding concurrent ventilation and chest compressions, tracheal suction for meconium and the use of medications. The author encourages readers who find this article helpful to register in an accredited NRP course to receive the extensive illustrated textbook and to benefit from the \"hands-on\" nature of the workshop.
