Esophageal perforation caused by an AMPLATZERTM vascular plug 4 occlusion device

This report describes an infant diagnosed with pulmonary atresia, ventricular septal defect, and multifocal collateral lung perfusion through four major aortopulmonary collateral arteries (MAPCAs). A central aorto‐pulmonary shunt was performed at 4 months of age. Because of postoperative pulmonary hyperperfusion, one of the MAPCAs was closed interventionally using a 5 mm AVP4. This MAPCA originated from the descending aorta (DAO) near the fifth thoracic vertebra and ran behind the esophagus to the lower lobe of the right lung. The MAPCA was closed near its origin from the DAO. Four weeks later, the patient presented with severe gastrointestinal bleeding, caused by perforation of the AVP4 into the esophagus. The occluder was extracted surgically, the MAPCA was clipped and the esophageal injury was sutured. To date, there have been no reports describing esophageal perforation due to an AVP4. The perforation in this patient may have been due to implantation of the AVP4 near the aorta in a MAPCA segment located directly in front of the spine and behind the esophagus. Another possible factor may have been the requirement for a gastrointestinal feeding tube. Although the occluder is soft and flexible, the spindle‐shaped ends may cause trauma if they are located close to other structures. © 2016 Wiley Periodicals, Inc.

Authors: Sugimoto K, Yoshihisa A, Nakazato K, Yokokawa T, Misaka T, Oikawa M, Kobayashi A, Yamaki T, Kunii H, Ishida T, Takeishi Y Abstract Pulmonary hypertension (PH) caused by left-sided heart disease (LHD-PH) is classified into 2 types: isolated post-capillary PH (Ipc-PH) and combined pre- and post-capillary PH (Cpc-PH). However, the impact of pulmonary vascular resistance (PVR) or diastolic pressure gradient (DPG) on the prognosis of LHD-PH has varied among previous studies. Thus, we verified the significance of PVR or DPG on the prognosis of LHD-PH in our series.We analyzed 243 consecutive LHD-PH patients. The...

Authors: Stević M, Vlajković M, Veličković F, Stanojević G, Nestorović M, Petrović F Abstract A 69 year old patient was admitted to hospital with massive gastrointestinal hemorrhage. The clinical presentation of the patient, except for bleeding, was dominated by the presence of neurofibromatosis type 1 - Von Recklinghausen disease. The patient was referred to multislice computed tomography (CT) angiography, magnetic resonance imaging (MRI), esophagogastroduodenoscopy and colonoscopy, which were performed without successful detection of the bleeding site. The MRI examination showed the existence of a tumor lo...

Authors: Štalc M, Jerman N, Trampuš M, Dolenc Novak M, Gužič Salobir B Abstract OBJECTIVE: To investigate the impact of myocardial perfusion scintigraphy results on the decision for invasive coronary angiography in elderly patients (≥75 years) with suspected coronary artery disease hospitalized in a single tertiary medical center. SUBJECTS AND METHODS: In the retrospective study, data of 276 (136 elderly) consecutive hospitalized patients referred to myocardial perfusion imaging were analyzed.

We present recent studies about newly developed or adjusted tools, the applicability of nutritional screening tools in specific populations, and how to implement screening in the overall process of improving nutritional care in the pediatric hospital setting. Summary Three new screening tools have been developed for use on admission to hospital: two for the mixed pediatric hospitalized population and one for infants. A simple weekly rescreening tool to identify hospital-acquired nutritional deterioration was developed for use in children with prolonged hospital stay. Different from most previous studies that only assess...

Conclusion: Here, we reveal several Nrf2 dose-responsive miRNA loci harboring putative upstream antioxidant response elements (AREs). Intriguingly, Nrf2-mediated miRNA responses were distinctly enriched for post-transcriptional regulation of cardiac-specific mRNAs. Altogether, these data reveal Nrf2 as a potent regulator of cardiac miRNA expression and provide novel candidates for future mechanistic investigation into the relationship between myocardial redox status and pathophysiology.
