Impact of catheterized ductal closure on renal and cerebral oximetry in premature neonates.

Percutaneous catheter-based closure is increasingly utilized in premature newborns. While near-infrared spectroscopy (NIRS) has been examined for assessment of interventional closure in surgical ligation, its application in percutaneous transcatheter closure remains unexplored. This study aims to assess cerebral and renal hemodynamic changes using NIRS during percutaneous closure compared to surgical closure in preterm infants.

Management of right ventricular outflow tract with percutaneous Melody valve implantation in pediatric patients: experience in a high complexity center in Colombia.

Background: Congenital heart disease poses a therapeutic challenge, specifically pulmonary valve stenosis. This has been treated for many years with invasive procedures and bioprostheses, which over time, become dysfunctional due to the accumulation of fibrous tissue and calcification.

Objective: The aim of this study is to describe the use of endovascular management in the right ventricular outflow tract, as the beginning of an ongoing effot to improve pediatric outcomes in developing countries.

Multicenter Experience for Early and Mid-Term Outcome of MyVal Transcatheter Pulmonary Valve Implantation.

Transcatheter pulmonary valve implantation (TPVI) is a surgical alternative for correcting dysfunctional right ventricular outflow tract in previously operated patients. MyVal transcatheter heart valve (THV) (Meril Life Sciences, India), a new transcatheter valve designed for aortic position has recently been reported to be implanted in pulmonary position. Myval transcatheter valve were implanted in patients with stenosed dysfunctional conduits, severe regurgitation from transannular patch or dysfunctional surgical pulmonary valves (Bioprosthesis).

Simultaneous transcatheter pulmonary and tricuspid valve-in-ring implantation.

We report on a 50-year-old female patient, with several severe comorbidities and high-surgical risk, in whom we successfully performed a simultaneous transcatheter pulmonary and tricuspid valve-in-ring implantation to treat both bioprosthetic pulmonary valve dysfunction and native torrential tricuspid valve regurgitation, the latter previously managed with a Carpentier annuloplasty ring.

Hybrid Procedures. Opening Doors for Surgeon and Cardiologist Close Collaboration.

Collaboration between cardiac surgeons and cardiologists can offer interventions that each specialist may not be able to offer on their own. This type of collaboration has been demonstrated with the hybrid Stage I in patients with hypoplastic heart syndrome. Since that time, a hybrid approach to cardiac interventions has been expanded to an incredible variety of potential indications.

Pediatrics Spanish Registry of Percutaneous Melody Pulmonary Valve Implantation in Patients Younger Than 18 Years.

Introduction And Objectives: A decade has passed since the first Spanish percutaneous pulmonary Melody valve implant (PPVI) in March 2007. Our objective was to analyze its results in terms of valvular function and possible mid-term follow-up complications.

Methods: Spanish retrospective descriptive multicenter analysis of Melody PPVI in patients < 18 years from the first implant in March 2007 until January 1, 2016.

Acquired Aseptic Intracardiac Shunts Following Transcatheter Aortic Valve Replacement: A Systematic Review.

Objectives: The aim of this study was to describe the incidence, mechanisms, features, and management of aseptic intracardiac shunts (AICS).

Background: AICS following transcatheter aortic valve replacement (TAVR) are an uncommon and barely described complication.

Methods: A systematic review was performed of all published cases of AICS following TAVR, and the incidence, predictors, main features, management, and related outcomes were analyzed.

Surgical Management of Vascular Stents in Pediatric Cardiac Surgery: Clues for a Staged Partnership.

Complex cases undergo step surgical and percutaneous procedures, including stent deployment. Concerns arise on stent removal at latest surgery. Our initial experience is presented.

Update on heart failure, heart transplant, congenital heart disease, and clinical cardiology.

In the year 2012, 3 scientific sections-heart failure and transplant, congenital heart disease, and clinical cardiology-are presented together in the same article. The most relevant development in the area of heart failure and transplantation is the 2012 publication of the European guidelines for heart failure. These describe new possibilities for some drugs (eplerenone and ivabradine); expand the criteria for resynchronization, ventricular assist, and peritoneal dialysis; and cover possibilities of percutaneous repair of the mitral valve (MitraClip(®)).

2013 update on congenital heart disease, clinical cardiology, heart failure, and heart transplant.

This article presents the most relevant developments in 2013 in 3 key areas of cardiology: congenital heart disease, clinical cardiology, and heart failure and transplant. Within the area of congenital heart disease, we reviewed contributions related to sudden death in adult congenital heart disease, the importance of specific echocardiographic parameters in assessing the systemic right ventricle, problems in patients with repaired tetralogy of Fallot and indication for pulmonary valve replacement, and confirmation of the role of specific factors in the selection of candidates for Fontan surgery. The most recent publications in clinical cardiology include a study by a European working group on correct diagnostic work-up in cardiomyopathies, studies on the cost-effectiveness of percutaneous aortic valve implantation, a consensus document on the management of type B aortic dissection, and guidelines on aortic valve and ascending aortic disease.

[Pediatric cardiology and congenital heart disease: from fetus to adult].

This article contains a review of some of the most important publications on congenital heart disease and pediatric cardiology that appeared in 2010 and up until September 2011. Of particular interest were studies on demographic changes reported in this patient population and on the need to manage the patients' transition from the pediatric to the adult cardiology department. This transition has given rise to the appearance of new areas of interest: for example, pregnancy in women with congenital heart disease, and the effect of genetic factors on the etiology and transmission of particular anomalies.

Ultrasound of the elbow.

This article describes the use of ultrasound (US) in the evaluation of the elbow. US is able to visualize several abnormalities affecting tendons, muscles, ligaments and bursae around the elbow joint as well as to delineate the nature of soft-tissue swelling, such as a space-occupying lesion or synovial enlargement. Occult fractures, osteophytes and intra-articular loose bodies can be depicted with this technique as well.

[Hemodynamic changes during laparoscopic surgery. Preliminary study].

The haemodynamic changes produced by laparoscopic surgery in children have been evaluated. A transesophageal echocardiographic study on 13 patients (7 males and 6 females, 10.8 +/- 2.

Bronchoesophageal fistula secondary to aspiration of tongue adhesion button in a child with glossoptosis.

A newborn boy with obstructive apnea secondary to glossoptosis was treated by securing his tongue to his lower lip. Soon after, the button that served for posterior fixation became detached and was thought to have been evacuated via the digestive tract. Twenty-two months later the infant presented with pneumonia involving the right lower lobe and hemoptysis, causing an acute respiratory distress syndrome (ARDS).
