Circulating biomarkers of left ventricular hypertrophy in pediatric coarctation of the aorta.

Congenit Heart Dis 2019 Jan 16. Epub 2019 Jan 16.

Division of Cardiology, Department of Pediatrics, University of Colorado Denver, Aurora, Colorado.

Objective: Patients undergoing surgical repair of aortic coarctation have a 50% risk of pathologic left ventricular remodeling (increased left ventricular mass or relative wall thickness). Endothelin 1, ST2, galectin 3, norepinephrine and B-natriuretic peptide are biomarkers that have been associated with pathologic LV change in adult populations but their predictive value following pediatric coarctation repair are not known.

Hypothesis: Biomarker levels at coarctation repair will predict persistent left ventricular remodeling at 1-year follow up. Read More

Predictive factors for residual hypertension following aortic coarctation stenting.

J Clin Hypertens (Greenwich) 2018 Dec 25. Epub 2018 Dec 25.

Department of Pediatric and Adult Congenital Cardiology, Hôpital Haut-Lévêque, University Hospital, Bordeaux, France.

Native coarctation of the aorta (CoA) and recoarctation (reCoA) after initial surgical repair are frequently associated with hypertension (HT). Most CoA cases are amenable to transcatheter balloon angioplasty with stent implantation; however, the impact of stenting on arterial blood pressure (BP) is variable. We carried out a retrospective study to identify the predictive factors for residual HT despite optimal endovascular treatment. Read More

Thomas Schachner

Multimed Man Cardiothorac Surg 2018 Nov 9;2018. Epub 2018 Nov 9.

Medizinische Universität Innsbruck Anichstrasse 35 6020 Innsbruck Austria.

Open surgery after failed endovascular aortic repair remains an important therapy. The potential modes of stent-graft failure include: type I endoleaks; progression of the aortic disease at the landing zones or proximal/distal to them persistent false lumen perfusion in post-dissection aneurysms; retrograde aortic dissection; stent-graft infection; and stent-graft collapse, fracture, or dislocation. The mortality associated with those procedures can be up to 20% depending on the complexity of the operation and the comorbidities of the patient, especially the presence of graft infection.

Congenital Thoracic Aortic Disease.

Radiol Clin North Am 2019 Jan;57(1):113-125

Department of Radiology, The University of Chicago, 5841 South Maryland Avenue, MC 2026, Chicago, IL 60637, USA.

Congenital abnormalities of the thoracic aorta encompass a variety of disorders with variable clinical manifestations ranging from asymptomatic to life threatening. A variety of imaging modalities are available for the evaluation of these anomalies with computed tomography (CT) commonly preferred due to its excellent spatial resolution and rapid acquisitions, avoiding the need of general anesthesia or even sedation. We review the embryology, imaging findings, and associations of multiple congenital thoracic aorta malformations with emphasis in the role of CT angiography in the evaluation of these pathologies.

Hybrid palliation as a bridge to biventricular repair in critical aortic stenosis with coarctation.

Ann Thorac Surg 2018 Nov 8. Epub 2018 Nov 8.

Division of Congenital Heart Surgery, Department of Surgery, Medical College of Wisconsin; Herma Heart Institute, Children's Hospital of Wisconsin.

Optimal management- balloon dilation versus surgical valvotomy- of neonatal critical aortic stenosis (AS) remains controversial. We describe a term neonate with critical AS and coarctation, severe left ventricular (LV) dysfunction with endocardial fibro-elastosis palliated with surgical valvotomy and hybrid as a bridge to early biventricular repair. Initial repair consisted of commissurotomy to create bicuspid morphology with placement of bilateral pulmonary artery bands and maintenance of ductal patency with prostaglandin. Read More

The Bicuspid Aortic Valve Condition: The Critical Role of Echocardiography and the Case for a Standard Nomenclature Consensus.

Prog Cardiovasc Dis 2018 Nov - Dec;61(5-6):404-415. Epub 2018 Nov 6.

Department of Cardiovascular Medicine, Mayo Clinic, Rochester, MN, USA.

The bicuspid aortic valve (BAV) condition is characterized by prominent heterogeneity of its valvular phenotypic expression, of its associated disorders, its complications and its prognosis. Echocardiography serves as the first-line imaging modality in 5 major capacities: (1) BAV diagnosis, (2) valvular phenotyping, (3) assessment of valvular function, (4) measurement of the thoracic aorta and exclusion of aortic coarctation, and (5) assessment of uncommon but serious complications such as infective endocarditis and aortic dissection. This article presents a nosological perspective on the BAV condition, discusses the critical role of echocardiography as it relates to these 5 aforementioned capacities; and makes the case for a unified standard nomenclature for the BAV condition.

[Treatment of an aortic arch aneurysm ruptured into the lung].

Angiol Sosud Khir 2018;24(3):169-175

Department of Vascular Surgery, Municipal Multimodality Hospital No2, Saint Petersburg, Russia.

Described herein is a clinical case report concerning treatment of a 32-year-old female patient with rupture of an aneurysm of the arch and descending portion of the thoracic aorta, with the bleeding having penetrated the upper lobe of the left lung. The woman was admitted to the Department of Vascular Surgery of Municipal Multimodality Hospital No 2 of Saint Petersburg, presenting with a clinical pattern of aneurysmal rupture previously diagnosed by computed tomography performed at one of the local hospitals. Studying her case history revealed that, when a child, she had endured an operation for a defect of the interventricular septum and aortic coarctation with aortoplasty using a Dacron synthetic patch.

Uncertainty Quantification for Non-invasive Assessment of Pressure Drop Across a Coarctation of the Aorta Using CFD.

Cardiovasc Eng Technol 2018 Dec 3;9(4):582-596. Epub 2018 Oct 3.

Institute for Imaging Science and Computational Modelling in Cardiovascular Medicine, Charité - Universitätsmedizin Berlin, Augustenburger Platz 1, Forum 4 - 0.0561, 13353, Berlin, Germany.

Purpose: Numerical assessment of the pressure drop across an aortic coarctation using CFD is a promising approach to replace invasive catheter-based measurements. The aim of this study was to investigate and quantify the uncertainty of numerical calculation of the pressure drop introduced during two essential steps of medical image processing: segmentation of the patient-specific geometry and measurement of patient-specific flow rates from 4D-flow-MRI.

Methods: Based on the baseline segmentation, geometries with different stenosis diameters were generated for a sample of ten patients. Read More
