Morphometric characteristics of the aorta and heart in situs inversus totalis.

Anat Cell Biol 2022 Jun;55(2):259-263

Department of Normal Anatomy, Danylo Halytsky Lviv National Medical University, Lviv, Ukraine.

Situs inversus totalis is a rare condition of visceral transposition in thoracic and abdominal cavities. Computed tomography (CT)-based morphometric analysis of the cardiovascular system prior to the surgery helps to describe vessel topography and size, choose the right surgical insertion site, avoid vessel trauma, and prevent hemorrhage during surgical intervention. We present a case report of situs inversus totalis detected incidentally in a 74-year-old male with the acute abdominal syndrome. Read More

Strategic two-step surgery using thoracic endovascular aortic repair for an infected thoracic aortic aneurysm.

Interact Cardiovasc Thorac Surg 2022 Jun 30. Epub 2022 Jun 30.

Department of Cardiovascular Surgery, Tokyo Metropolitan Bokutoh Hospital, Tokyo, Japan.

An 81-year-old man with multiple comorbidities developed infected thoracic aortic aneurysm, and we employed a strategic two-step surgical approach combining thoracic endovascular aortic repair and local debridement with an omental flap during the active phase of infection. No signs of reinfection were observed at the 1-year follow-up. This strategy can be a safe and less invasive alternative to conventional open surgery in patients with high surgical risk. Read More

Adventitia-derived extracellular matrix hydrogel enhances contractility of human vasa vasorum-derived pericytes via α β integrin and TGFβ receptor.

J Biomed Mater Res A 2022 Jun 30. Epub 2022 Jun 30.

Department of Cardiothoracic Surgery, University of Pittsburgh, Pittsburgh, Pennsylvania, USA.

Pericytes are essential components of small blood vessels and are found in human aortic vasa vasorum. Prior work uncovered lower vasa vasorum density and decreased levels of pro-angiogenic growth factors in adventitial specimens of human ascending thoracic aortic aneurysm. We hypothesized that adventitial extracellular matrix (ECM) from normal aorta promotes pericyte function by increasing pericyte contractile function through mechanisms deficient in ECM derived from aneurysmal aortic adventitia.

Palliative Repair of a Mycotic Aortic Arch Pseudoaneurysm With a Physician-Modified Endograft and In-Situ Laser Fenestration.

J Endovasc Ther 2022 Jun 29:15266028221107879. Epub 2022 Jun 29.

Division of Cardiothoracic Surgery, Department of Surgery, Medical University of South Carolina, Charleston, SC, USA.

Purpose: Open aortic arch repair is the gold standard in the treatment of diseases involving the ascending aorta and aortic arch. However, due to the invasive nature of open repair, high-risk patients with multiple comorbidities are often not suitable candidates for open surgical repair. While endovascular aortic repair is far less invasive, endovascular arch repair remains a difficult challenge due to the aortic arch diameter and angulation, origin of the supra-aortic arteries, and the lack of commercially available thoracic branched devices in the United States.

Misdiagnosis of Thoracic Aortic Emergencies Occurs Frequently Among Transfers to Aortic Referral Centers: An Analysis of Over 3700 Patients.

J Am Heart Assoc 2022 Jun 29:e025026. Epub 2022 Jun 29.

Division of Cardiac Surgery, Department of Cardiothoracic Surgery University of Pittsburgh Pittsburgh PA USA.

Background Acute aortic syndromes may be prone to misdiagnosis by nonreferral aortic centers with less diagnostic experience. We evaluated regional variability in these misdiagnosis trends among patients transferred to different regional quaternary care centers with presumed acute aortic syndromes.

Authors:
Xuehuan He Jia Lu

Acta Biomater 2022 Jun 24. Epub 2022 Jun 24.

Department of Mechanical Engineering, and Iowa Technology Institute The University of Iowa, Iowa City, IA 52242, USA. Electronic address:

We propose a new approach for constructing strain-based rupture criterion for ascending thoracic aortic aneurysm. The rupture metric is formulated using an effective strain, which is a measure of net strain that the collagen bundles experience after fiber uncrimping. The effective strain is a function of the total strain and the waviness properties of the collagen fibers. Read More

[Fenestrated and branched endovascular aortic prostheses : An update].

Radiologie (Heidelb) 2022 Jul 20;62(7):586-591. Epub 2022 Jun 20.

Abteilung für Kardiovaskuläre und Interventionelle Radiologie, Universitätsklinik für Radiologie und Nuklearmedizin, Medizinische Universität Wien, Währinger Gürtel 18-20, 1090, Wien, Österreich.

Background: Today, complex abdominal aortic pathologies involving the visceral arteries and without an adequate proximal neck can be treated using fenestrated/branched endovascular aortic repair (FEVAR/BEVAR) with similar safety and success rates as infrarenal aortic pathologies treated with tubular EVAR.

Methodical Innovations And Challenges: Fenestrations (if the vessel originates from a nondilated aorta) or branches (if the vessel originates from a dilated aorta) may be used for the visceral arteries. Both types of openings are sealed via bridging stent grafts that connect to the target vessel. Read More

J Formos Med Assoc 2022 Jun 15. Epub 2022 Jun 15.

Department of Surgery, Cardiovascular Section, National Taiwan University Hospital, Taipei, Taiwan; Graduate Institute of Clinical Medicine, College of Medicine, National Taiwan University, Taipei, Taiwan. Electronic address:

Background: Thoracic endovascular aortic repair (TEVAR) can only promote 55-80% false lumen (FL) thrombosis when only the proximal primary tear is covered during the repair of type B aortic dissection (TBAD). This study evaluated the effectiveness and clinical outcome of tailored exclusion of the primary entry tear with TEVAR and distal fenestrations with ancillary devices in patients with subacute or chronic Crawford type III and IV aortic dissection aneurysm.

Methods: All patients underwent either TEVAR for primary entry tear; subsequently, various ancillary devices were applied on each distal fenestration. Read More

A poor outcome in non-occlusive thrombo-embolic limb ischaemia related to the dislocation of mural thrombus from an abdominal aortic aneurysm.

BMC Cardiovasc Disord 2022 Jun 18;22(1):277. Epub 2022 Jun 18.

Division of NeuroSurgery, Department of Surgery, Chang Gung Memorial Hospital, Linkou, Chang Gung University, Taoyuan, Taiwan.

Background: Acute thrombosis of an abdominal aortic aneurysm with acute limb ischaemia is an unusual complication and is associated with high mortality. Dislocation of the intrasaccular mural thrombus could be one of the mechanisms. For the most part, acute limb ischaemia presents with absent pulses, compatible with the clinical findings, which include pain, paraesthesia, and paralysis. Read More

Sports Participation and Physical Activity in Individuals with Heritable Thoracic Aortic Disease and Aortopathy Conditions.

Clin Sports Med 2022 Jul;41(3):511-527

Marfan Syndrome and Aortopathy Clinic, Aortopathy and Master Clinician Fellowship Program, Cardiovascular Division, John T. Milliken Department of Medicine, Washington University School of Medicine, 660 South Euclid Avenue, Box 8086, St. Louis, MO 63110, USA. Electronic address:

The evaluation and management of athletes with HTAD and aortopathy conditions requires shared decision-making encompassing the underlying condition, family history, aortic diameter, and type and intensity of sports and exercise. Mouse models of thoracic aortic disease show that low-to-moderate-level aerobic exercise can maintain aortic architecture and attenuate pathologic aortic root dilation. Although controlled trials in human are lacking, recreational physical activities performed at a low-to-moderate aerobic pace are generally low risk for most individuals with aortopathy conditions.

False Lumen Flow Assessment by Magnetic Resonance Imaging and Long-Term Outcomes in Uncomplicated Aortic Dissection.

J Am Coll Cardiol 2022 Jun;79(24):2415-2427

Departament de Cardiologia, Hospital Vall d'Hebron, CIBERCV, Universitat Autonoma de Barcelona, Barcelona, Spain.

Background: Despite the absence of clinical complications after an acute aortic dissection (AD) with persistent patent false lumen (FL), a high risk for clinical events may persist.

Objectives: The aim of this study was to assess the natural evolution of noncomplicated AD and ascertain whether different FL flow patterns by magnetic resonance imaging (MRI) have independent prognostic value for AD-related events beyond established morphologic parameters.

Methods: One hundred thirty-one consecutive patients, 78 with surgically treated type A dissections and 53 with medically treated type B dissections, were followed up prospectively after acute AD with persistent patent FL in the descending aorta. Read More
