Patent ductus arteriosus (PDA) stenting has gained acceptance for palliation in cyanotic congenital heart disease. The PDA in tetralogy of Fallot with pulmonary atresia (ToF-PA) arises, in the left aortic arch, from underneath the arch and connects to the proximal left pulmonary artery, often resulting in stenosis. The PDA is usually elongated and tortuous, making stent implantation challenging. Shorter duration of palliation, aggravation of branch pulmonary artery stenosis resulting in poor growth and difficulty at surgery makes ductal stenting controversial...

BACKGROUND: Right ventricular outflow tract (RVOT) stents have been used as palliation in patients with severe tetralogy of Fallot (TOF). Radiofrequency perforation of the RVOT has also been described in patients with pulmonary atresia (PA)/ventricular septal defect (VSD). However, RVOT stenting in conjunction with radiofrequency perforation as a means for establishing reliable pulmonary blood flow in patients with PA/VSD has not previously been reported. OBJECTIVES: Our aim is to report our experience with using perforation of plate-like pulmonary valve atresia combined with stenting of RVOT as an alternative and equally efficacious intervention for infants with PA/VSD, as compared to a surgical pulmonary artery shunt (SPS)...

REVIEW
Colin Wallis, Clare A McLaren
Tracheobronchomalacia is a rare but clinically troublesome condition in paediatrics. The softening of the major airways - which can include some or all of the tracheobronchial tree can lead to symptoms ranging from the minor (harsh barking cough, recurrent chest infections) to severe respiratory difficulties including prolonged ventilator support and 'near death attacks'. The causes are broadly divided into intrinsic softening of the airway wall which is considered a primary defect (e.g. syndromes; post tracheo-oesophageal fistula repair; extreme prematurity) or secondary malacia due to external compression from vascular structures or cardiac components...

BACKGROUND: Although reducing the incidence of unplanned readmission after thoracoabdominal aortic aneurysm (TAAA) repair represents an important opportunity to improve outcomes, predictors of readmissions are not known. We sought to characterize and identify factors associated with unplanned readmission after discharge in survivors of open TAAA repair. METHODS: Through prospective phone contact and retrospective record review, we determined the frequency and characteristics of unplanned readmissions within 30 days of discharge in 363 patients who were discharged after open TAAA repair...

We present the case of a 69-year-old patient who was referred to the Department of Echocardiography for surgical treatment of severe tricuspid valve regurgitation (TVR) with advanced congestive heart failure. In 2013 the patient underwent unsuccessful percutaneous ablation for permanent atrial fibrillation. In 2015, following numerous episodes of atrial fibrillation and congestive heart failure with left pleural effusion, the patient was admitted to another center. A transthoracic echocardiogram showed severe TVR and moderate precapillary pulmonary hypertension, confirmed at right cardiac catheterization...

A 14-year-old female was referred for severe pulmonary valve insufficiency after undergoing radiofrequency ablation for a right ventricular outflow tract tachycardia that originated in the proximal pulmonary artery at 10 years of age. Clinical records indicated that ablation was guided solely by electrograms and electroanatomical mapping. Due to myocardial tissue extensions, mapping failed to identify the level of the pulmonary valve annulus, which resulted in delivery of energy on the valve proper and into the pulmonary artery...

Children requiring reimplantation of a branch pulmonary artery (PA) are at risk for postoperative stenosis and impaired growth of the reimplanted PA. Outcomes and risk factors for reintervention and impaired growth are incompletely described. We reviewed data on patients who underwent reimplantation of a branch PA between 1/1/99 and 5/1/15 at a single center. The primary outcome was reintervention to treat postoperative stenosis. The secondary outcome was "catch-up" growth (faster diameter growth of the affected PA compared with the unaffected PA from the preoperative to follow-up measurements...

Background -Infants with ductal-dependent pulmonary blood flow may undergo palliation with either a patent ductus arteriosus (PDA) stent or modified Blalock-Taussig (BT) shunt. A balanced multi-center comparison of these two approaches is lacking. Methods -Infants with ductal-dependent pulmonary blood flow, palliated with either PDA stent or BT shunt from 1/08 to 11/15, were reviewed from the four member centers of the Congenital Catheterization Research Collaborative. Outcomes were compared using propensity score adjustment to account for baseline differences between groups...

When the inferior caval vein is occluded or abnormal, jugular and hepatic veins provide alternative routes for interventions. For pulmonary artery stenting, transhepatic access may give a relatively straighter route than that from the jugular veins. We describe the challenges and strategies during transhepatic bilateral pulmonary artery stenting after arterial switch operation complicated by occluded inferior caval vein and congested hepatic veins.

BACKGROUND: Perioperative management of antiplatelet therapy for patients undergoing pulmonary resection must balance the risk of cardiovascular events with that of hemorrhage. An optimal approach has not been defined in this population. We sought to characterize outcomes of patients undergoing pulmonary lobectomy on antiplatelet therapy with clopidogrel. METHODS: A prospective institutional database was retrospectively reviewed to identify all patients undergoing pulmonary lobectomy from 2007 to 2015 who received perioperative clopidogrel...

BACKGROUND: Meaningful translational large animal models for cardiac diseases are indispensable for studying disease mechanisms, development of novel therapeutic strategies, and evaluation of potential drugs. METHODS: For induction of heart failure, cardiac hypertrophy and fibrosis, a bare metal stent was implanted in the descending aorta of growing pigs (n = 7), inducing pressure stress on the left ventricle (group HYPI). The constant stent size in growing pigs resulted in antegrade partial obstruction of the aortic flow with a gradual increase in afterload...

BACKGROUND: Motion artifacts may degrade CT examination of Fontan pathway and hinder accurate diagnosis of in-stent restenosis. PURPOSE: We retrospectively compared ECG-gated multi-detector computed tomography (CT) with non-ECG-gated CT in order to demonstrate whether or not one of the methods should be preferred. METHOD: The study included 13 patients with surgically reconstructed Fontan pathway. A total of 16 CT examinations were performed between February 2010 and November 2015...
