    Minimally Invasive Surgical Technique in Double Aortic Arch with Distal Atretic Left-Side in Infant: From a Single-Surgeon Clinical Experience

    Qi Liu, Shoujun Li, Zhongdong Hua*

    Congenital Heart Disease, Vol.17, No.5, pp. 533-539, 2022, DOI:10.32604/chd.2022.020496 - 06 September 2022

    Abstract Background: Double aortic arch (DAA) with distal left-sided aortic arch atresia (LAAA) can form complete vascular ring by ligamentum connection. We aimed to introduce an uncommon DAA-LAAA diagnosis and treatment by the minimally invasive surgical technique (MIST). Methods: We retrospectively reviewed 7 cases of DAA-LAAA that were treated from January 2017 to July 2021. All infant patients underwent surgical repair by minimally invasive surgical technique. Mean follow-up was 14.43 months (range, 5–21 months). Results: There were seven patients with DAA-LAAA, including six males and one female. Median age was 19.29 months (range, 9.0–29.0 months). Median weight was… More > Graphic Abstract

    CASE REPORT

    2q37.3 Deletion with Complex Heart Defects Suggesting Interruption of Early Ventricular Looping

    Sanam Safi1,2, Takato Yamasaki1,3, David J. Glidden4, Stephen P. Sanders1,5, Chrystalle Katte Carreon1,6,*

    Congenital Heart Disease, Vol.17, No.2, pp. 141-146, 2022, DOI:10.32604/chd.2022.019743 - 26 January 2022

    Abstract A maternally inherited 828 kb microdeletion of 2q37.3 manifested in a 3-week-old premature boy as left juxtaposition of the atrial appendages associated with tricuspid atresia, double outlet infundibulum, subvalvar pulmonary atresia, large secundum atrial septal defect, and right aortic arch with mirror-image branching, consistent with developmental arrest early in heart looping. To the best of our knowledge, no previous 2q37 deletion syndrome has been reported with such a severe cardiac dysmorphology. Hence, this case adds to the cardiac phenotypes identified in 2q37 deletion syndrome. More >

    CASE REPORT

    Isolation of the Left Subclavian Artery in D-Transposition of the Great Arteries with Right Aortic Arch

    Kotaro Hine*, Kohei Ogata, Keiko Saitou, Norio Mizukaki, Hiroko Arai, Hitoshi Yoda

    Congenital Heart Disease, Vol.16, No.4, pp. 369-371, 2021, DOI:10.32604/CHD.2021.014516 - 19 April 2021

    Abstract Abnormal branching of the aorta associated with the right aortic arch (RAA) has been reported as isolation of left subclavian artery (ILSA), isolation of left common carotid artery, isolation of brachiocephalic artery. ILSA is a rare aortic branch anomaly that originates in the left subclavian artery from the pulmonary artery via ductus arteriosus. Several reports have described ILSA associated with 22q11.2 deletion syndrome and tetralogy of Fallot. Here, we present a very unusual case of RAA with ILSA associated with D-transposition of the great arteries and inferior vena cava interrupted with azygos continuation. More >

    Kinematic and Dynamic Characteristics of Pulsating Flow in 180o Tube

    Tin-Kan Hung1,*, Ruei-Hung Kuo2, Cheng-Hsien Chiang3

    Molecular & Cellular Biomechanics, Vol.17, No.1, pp. 19-24, 2020, DOI:10.32604/mcb.2019.07817

    Abstract Kinematic and dynamic characteristics of pulsating flow in a model of human aortic arch are obtained by a computational analysis. Three-dimensional flow processes are summarized by pressure distributions on the symmetric plane together with velocity and pressure contours on a few cross sections for systolic acceleration and deceleration. Without considering the effects of aortic tapering and the carotid arteries, the development of tubular boundary layer with centrifugal forces and pulsation are also analyzed for flow separation and backflow during systolic deceleration.

    ABSTRACT

    The Degree of Question Mark of Aorta Can Predict the Thrombosis Rate in the False Lumen of a Type-B Aortic Dissection After TEVAR

    Da Li1,#, Liqing Peng2,#, Yi Wang3, Ding Yuan4, Tinghui Zheng1,*

    Molecular & Cellular Biomechanics, Vol.16, Suppl.1, pp. 39-39, 2019, DOI:10.32604/mcb.2019.05718

    Abstract Objective: Thoracic endovascular aortic repair (TEVAR) of type B aortic dissection (AD) is to initiate the thrombosis in the false lumen to eventually result in aortic remodeling. We aim to find out whether the false lumen (FL) thrombosis rate after TEVAR can be predicted accurately by an index that expresses the degree of aortic arch angulation. Method: Three-dimensional aortic arch geometry of 39 type B AD patients (mean age: 48 years) after TEVR were reconstructed from post-operative CT images. For the first time, the question mark which takes into account the curvature of both aortic arch… More >

    Right aortic arch with situs solitus

    William N. Evans1,2, Ruben J. Acherman1,2, Dean Berthoty3, Gary A. Mayman1,2, Michael L. Ciccolo1,4, Sergio A. Carrillo1,4, Humberto Restrepo1,2

    Congenital Heart Disease, Vol.13, No.4, pp. 624-627, 2018, DOI:10.1111/chd.12623

    Abstract Patients: We reviewed all patients evaluated at our center with situs solitus, levocardia, and a right aortic arch that were born between January 2000 and January 2018. Results: From our databases, we identified 204 patients. We excluded patients with a double aortic arch from analysis. Of the 204 patients, 103 (50%) were male. Of the 204 patients, 95 (47%) had an isolated right aortic arch. Of the 95 with an isolated right aortic arch, 4 (4%) had chromosome 22q11.2 deletion syndrome, and 89 (94%) had a vascular ring. Of the 204 patients, 109 (53%) had a… More >

    Preoperative echocardiographic measures in interrupted aortic arch: Which ones best predict surgical approach and outcome?

    Ginnie Abarbanell1, William L. Border2, Brian Schlosser2, Gemma Morrow2, Michael Kelleman2, Ritu Sachdeva2

    Congenital Heart Disease, Vol.13, No.3, pp. 476-482, 2018, DOI:10.1111/chd.12599

    Abstract Objective: It is unclear whether neonates with interrupted aortic arch (IAA) and a smaller left ventricular outflow tract may have improved outcomes with a Yasui operation (ventricular outflow bypass procedure) over a primary complete repair. This study sought to identify preoperative echocardiographic parameters to differentiate which neonates may have improved outcomes with a primary vs Yasui operation.
    Design: Patient demographics, cardiac surgery type, complications, need for reoperation and/or interventional catheterization, and date of last follow-up were collected on neonates who underwent a biventricular repair for IAA from 2003 to 2014. Preoperative echocardiograms were analyzed for: IAA type,… More >

    Right aortic arch with situs solitus frequently heralds a vascular ring

    William N. Evans1,2, Ruben J. Acherman1,2, Michael L. Ciccolo1,3, Sergio A. Carrillo1,3, Gary A. Mayman1,2, Carlos F. Luna1,2, Robert C. Rollins1,2, William J. Castillo1,2, Alvaro Galindo1,2, Abraham Rothman1,2, John A. Alexander1,2, Tina W. Kwan1,2, Humberto Restrepo1,2

    Congenital Heart Disease, Vol.12, No.5, pp. 583-587, 2017, DOI:10.1111/chd.12487

    Abstract Objective: We hypothesized that a right aortic arch in situs solitus, with or without an associated cardiovascular malformation, is often associated with a vascular ring.
    Methods: From those born in Southern Nevada between March 2012 and March 2017, we identified 50 (3.6 per 10,000 live births) with a right aortic arch and situs solitus. From the 50 patients, 6 did not meet inclusion criteria for further analysis.
    Results: Of the 44 remaining, 33 (75%) had a vascular ring. Of the 33 with a vascular ring, 26 (79%) occurred with an isolated right aortic arch, and 7 (21%) had More >

    ABSTRACT

    Stress Analysis in Layered Aortic Arch model: Influence of Arch Aneurysm and Wall Stiffness

    F. Gao1, D. Tang2∗, Z. Guo3, Makoto Sakamoto4, T. Matsuzawa5

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.1, No.1, pp. 21-28, 2007, DOI:10.3970/icces.2007.001.021

    Abstract Patients with aortic aneurysm, especially aortic arch aneurysm, are prone to aortic dissection. For investigation of the effects of aneurysm and wall stiffness on wall stress distribution, a nonaneurysm arch model as well as an aneurysm arch model was constructed. The fluid structure interaction was implemented in the arch model of aorta. The results show that the stresses are much higher at inflection points in the aneurysm model than in nonaneurysm model, and the stresses at media in stiffened wall are higher than in unstiffened wall. The high composite stress is located at inflection points More >
