Endovascular stent-grafting is an alternative treatment for adult patent ductus arteriosus (PDA), especially in elderly patients. Regarding young adults, endovascular therapy is a reasonable choice if the landing zone is sufficient. In this study, we report on a young adult with PDA successfully treated with endovascular stent-grafting.

Esophageal cancer is one of the six most common cancers in the world, constituting ∼7% of the gastrointestinal cancers. Esophageal stents can be inserted into the esophagus to open the pathway as a palliative treatment for advanced esophageal cancer. For the treatment of esophageal cancer, a series of anticancer drug-loaded stents such as paclitaxel or 5-fluorouracil/esophageal stent combinations have been prepared by covering a nitinol stent with a polymer or hydrogel shell. For the first time, we developed a gold nanoshell (AuNS)-coated stent with high photothermal efficiency and used in the repetitive photothermal therapy of esophageal cancer...

We report interventional re-opening of a PDA for reverse Potts shunt circulation 12 months after closure in a 3.8 year old child, suffering from right ventricular (RV) failure due to suprasystemic pulmonary artery hypertension (PAH) after ADO I implantation. After ex vivo simulation, perforation through the mesh of the ADO I with the use of transseptal needle, wire looping (AO-PA), balloon dilatation, stent implantation (Palmaz 6 mm) and post dilatation, a reverse Pott-shunt circulation was established. A follow-up period of 11 months was achieved with preserved RV function and reverse Pott shunt circulation maintained a post ductal saturation of 94-88%...

Test occlusion with a balloon is done to predict operability of large hypertensive patent ductus arteriosus (PDA). If the fall in the pulmonary artery pressures is inadequate, a complete closure is not desired. To create a predictable premeasured fenestration in a nitinol occluder device used for closing hypertensive PDA. A large nitinol occluder device was punctured with an 18G needle to advance a 0.035˝ stiff guide wire through the occluder before loading it into the delivery system. The occluder with the guidewire was then deployed across the PDA...

True aneurysm of pancreaticoduodenal arcade (PDA) is usually accompanied by stenosis or occlusion of celiac trunk (CeT). The up-to-date and first choice treatment modality of PDA aneurysm is the endovascular approach in nearly all cases except few selected ones necessitating surgery. The main approach in endovascular treatment is embolization of the aneurysm by preserving the parent artery. A case with concomitant CeT occlusion and PDA aneurysm was treated with coil embolization by preserving inferior pancreaticoduodenal artery with retrievable Solitaire(®) stent...

BACKGROUND: Carotid artery access in infants with congenital heart disease undergoing cardiac catheterization via a surgical cut down has been well described. There is a paucity of information regarding percutaneous carotid artery (CA) access in infants <3 months. METHODS: A retrospective review of infants <3 months of age undergoing cardiac catheterization via percutaneous CA approach was performed after IRB approval. Between January 2012 and May 2015, 18 patients underwent 20 procedures; median age 13 days (2-77); median weight 3...

BACKGROUND: Inadvertent ligation of the left pulmonary artery during attempted surgical closure of a Patent Ductus Arteriosus has long been recognized as one of the less common complications of this procedure. Surgical reconstruction of the left pulmonary artery was then often attempted but was difficult or impossible in some of the patients with hypoplasia of the left pulmonary artery and the left lung. CASE PRESENTATION: A 10-year-old girl presented with marked exercise intolerance and palpitations and was diagnosed to have large PDA...

Closure of a patent ductus arteriosus (PDA) in the elderly is a high-risk procedure because of tissue fragility and many possible complications. The patient in our case was an 81-year-old woman with a window-type PDA caused by cardiac failure. Based on the anatomy of the PDA and aorta and to minimize invasion, we used a stent graft to close the PDA. This approach was successful; hemodynamics improved and ductus flow was eliminated during the follow-up period without intervention from the pulmonary artery side...

The results of Hybrid procedure (HP) for the hypoplastic left heart syndrome (HLHS) depend on several variables: pulmonary artery banding tightness (PAB), atrial septal defect size (ASD) and patent ductus arteriosus stent size (PDA). A HP complication could be the aortic coarctaction (CoAo). The reverse Blalock-Taussig shunt (RevBT) placement was proposed to avoid CoAo effects. This work aims at developing a lumped parameter model (LPM) to investigate the effects of the different variables on HP haemodynamics...

BACKGROUND: The hybrid palliation for hypoplastic left heart syndrome has emerged as an alternative approach to the Norwood procedure. The development of patent ductus arteriosus (PDA) in-stent stenosis can cause retrograde aortic arch stenosis (RAAS), leading to significant morbidity. This study aimed to identify potential mechanisms of PDA in-stent stenosis contributing to RAAS. METHODS: Tissues from stented PDAs were collected from 17 patients undergoing comprehensive stage II repair between 2009 and 2014...

Patent ductus arteriosus (PDA) is sometimes undetected until adulthood, and surgical closure of a PDA is dangerous because of the calcification of the ductus. Percutaneous approaches such as coil embolization and use of a PDA occluder are less invasive; however, these devices are not suitable for PDA with thoracic aortic aneurysm (TAA). We present the case of a 72-year-old female patient who underwent successful stent graft insertions for PDA with TAA.

BACKGROUND: The National Cardiovascular Data Registry (NCDR) launched the IMPACT (Improving Pediatric and Adult Congenital Treatment) Registry in 2010. By 2013, its patient enrollment exceeded that of other current and historical congenital catheterization registries. OBJECTIVES: This study sought to describe procedural results and safety of 6 common congenital interventions performed in patients enrolled during the IMPACT Registry's initial periods. METHODS: With specified exclusions, we compiled registry data from patients enrolled in the IMPACT Registry from January 2011 through March 2013 who underwent 1 of the following isolated procedures: device closure of atrial septal defect (ASD); device closure of patent ductus arteriosus (PDA); pulmonary valvuloplasty; aortic valvuloplasty; coarctation of the aorta angioplasty and stenting; and pulmonary artery stenting...

Coarctoplasty with stenting is often an effective strategy in cases of recoarctation following surgical repair. The potential benefit of coarctoplasty in a patient with Eisenmenger's syndrome is unknown. We describe the case of a 21-year-old male who presented with claudication of lower limbs. He was known to have congenital heart disease, consisting of ventricular septal defect, patent ductus arteriosus (PDA), and coarctation of the aorta. Coarctation repair and PDA ligation had been done at two months of age...

In this report, we present a rare association between Ebstein anomaly (EA) and isovaleric acidemia (IVA) in a newborn who was admitted to our cardiac center. He underwent for PDA stenting to maintain adequate pulmonary blood flow, later he developed recurrent metabolic acidosis, prominent sweaty feet odor, neutropenia and thrombocytopenia. His organic acids profile in the urine confirmed the diagnosis of IVA. To the best of our knowledge, there is no association between these two rare diseases. We are presenting this case report to highlight this rare association...

INTRODUCTION: Balloon expandable stents are an integral part in the catheter treatment of congenital heart disease. In the growing child, stents require dilatation to greater diameters over time. The Cook Formula stent is a recent 316 stainless steel open-cell design licensed for peripheral vascular work. METHODS: Following extensive ex vivo studies, 112 stents were implanted in 97 children [median age 3.9 (0.01-17.6) years; median weight 13.7 (2.4-62.8) kg] over a 27-month (Oct 2011-Dec 2013) period...

BACKGROUND: Hybrid procedure is an alternative initial palliation for patients with hypoplastic left heart syndrome (HLHS). One major complication with this procedure is stenosis in the aortic arch isthmus possibly due to inflammation from the patent ductus arteriosus (PDA) stent. In adult studies, neutrophil/lymphocyte (N/L) ratio has been used as a marker for increased inflammation and has been associated with increased risk for coronary artery stent stenosis. The goal of this study was to determine if there were differences in N/L ratio between patients with HLHS undergoing hybrid procedure that required an arch intervention (AI-Group) vs...

BACKGROUND: The surgical creation of a Potts shunt has been reported in children with suprasystemic idiopathic pulmonary artery (PA) hypertension (IPAH) refractory to any medical therapy. This surgical approach allows acute decompression of the right ventricle (RV) and thereby avoids ventricular failure. We present 4 newborns and infants with different causes of pulmonary hypertension (PH) in whom interventional stenting of the patent ductus arteriosus (PDA) was used to create a "functional" Potts shunt...

During the past decade, drug-eluting stents (DES) have been widely used for the treatment of occlusive coronary artery diseases. They are supposed to reduce the incidence of early in-stent restenosis by the elution of highly hydrophobic antiproliferative drugs. Nevertheless, the absence of long-term activity of these devices is responsible for late acute thrombosis probably due to the delayed re-endothelialization of the arterial wall over the bare metallic stent struts. Thus, a new generation of DES with a sustained release of therapeutic agents is required to improve long-term results of these devices...
