Percutaneous implantation of the CoreValve® self-expanding valve prosthesis in patients with severe aortic stenosis and porcelain aorta: medium-term follow-up.

INTRODUCTION AND OBJECTIVES: There is little information on the use of transcatheter aortic valve implantation in patients with severe aortic stenosis and porcelain aorta. The primary aim of this study was to analyze death from any cause after CoreValve(®) implantation in patients with severe aortic stenosis, with and without porcelain aorta. METHODS: In this multicenter, observational prospective study, carried out in 3 hospitals, percutaneous aortic valves were implanted in 449 patients with severely calcified aortic stenosis. Of these, 36 (8%) met the criteria for porcelain aorta. The prim

The location of the primary entry tear in acute type B aortic dissection affects early outcome.

OBJECTIVES: The goal of the retrospective study was to relate the site of the primary entry tear in acute type B aortic dissections to the presence or development of complications. METHODS: A consecutive series of 52 patients referred with acute type B aortic dissection was analysed with regard to the location of the primary entry tear (convexity or concavity of the distal aortic arch) using the referral CT scans at the time of diagnosis. These findings were related to the clinical outcome as well as to the need for intervention. RESULTS: Twenty-five patients (48%) had the primary entry tear

Effectiveness of intensive medical therapy in type B aortic dissection: a single-center experience.

OBJECTIVE: Although the mainstay of managing acute descending thoracic aortic dissection (ADTAD) remains medical, certain patients will require emergency surgery for complications of rupture or ischemia. This study evaluates factors that affect outcome and determines which patients previously treated surgically would have been eligible for endovascular repair. METHODS: A single-institution retrospective study was conducted of patients who presented with clinical signs of ADTAD that was confirmed by magnetic resonance angiography (MRA) or computed tomography (CT). All patients were admitted to

MR and CT angiography in the diagnosis of vasculitides.

Vasculitides represent the wide-ranging series of complex inflammatory diseases that involve inflammation of blood vessel walls. These conditions are characterized according to the caliber of the predominantly involved vessels. The work-up of vasculitides often includes imaging to narrow a differential diagnosis and guide management. Findings from CT and MR angiography in conjunction with a thorough history and physical exam are of utmost importance in making an accurate diagnosis. Further, imaging can be used for follow-up, in order to monitor disease progression and response to treatment. Th

Complications after aortic arch hybrid repair.

OBJECTIVES: To analyze early and midterm complications after hybrid aortic arch repair (HAR). METHODS: Between January 1997 and November 2009 among 259 patients receiving thoracic endovascular aortic repair, HAR has been performed in 47 patients (median age, 64.5 years; range, 41-84). A retrospective analysis was performed. Complete supra-aortic debranching was performed in 15 patients (32%) and partial debranching in 23 patients (49%). Isolated left subclavian artery revascularization prior to thoracic endovascular aortic repair has been used in nine patients (19%). Emergency procedures were

Transglutaminase type 2 in human abdominal aortic aneurysm is a potential factor in the stabilization of extracellular matrix.

OBJECTIVE: The aim of this study was to evaluate transglutaminase type 2 (TG2) expression in human abdominal aortic aneurysm (AAA) tissue and to elucidate a potential role of TG2 in AAA formation. TG2, which is a Ca(2+)-dependent cross-linking enzyme, has been proven important for stabilizing the extracellular matrix. However, there is no evidence of the effect of TG2 on AAA formation in a human model. METHODS: Aortic wall tissues were obtained during surgery in AAA patients (n = 38) and in patients with aortoiliac occlusive disease (Control; n = 4) in the Asan Medical Center from March 2011

Primary angiosarcoma of the aorta, great vessels, and the heart.

OBJECTIVE: Primary angiosarcomas originating from the heart, aorta, or great vessels are extremely rare and hence poorly understood. We reviewed our experience to identify a preferred diagnostic and treatment strategy and evaluate the role of adjunctive therapy. METHODS: We reviewed the clinical data of all patients diagnosed with primary angiosarcoma of the heart, aorta, and great vessels from 1985 to 2011, including presentation, diagnosis, management, and outcomes. RESULTS: Thirteen patients (five males and eight females; mean age, 54 ± 4 years) had primary angiosarcoma arising from the a

Aortic pseudoaneurysm due to graft infection after invasive thymoma resection.

A 69-year-old woman with invasive thymoma underwent chemoradiotherapy followed by surgical resection, including extended thymectomy, right upper lobectomy, and innominate vein and superior vena cava reconstruction with a polytetrafluoroethylene graft. Computed tomography on the 27th postoperative day revealed mediastinitis and right hemothorax; open debridement and evacuation were performed. Vacuum-assisted closure was initiated to heal the median incision. The wound gradually cleared, and the vacuum was terminated on the 150th postoperative day. On the 155th postoperative day, the patient suf

Adherence to postoperative surveillance guidelines after endovascular aortic aneurysm repair among Medicare beneficiaries.

OBJECTIVE: After endovascular aortic aneurysm repair (EVAR), the Society for Vascular Surgery recommends a computed tomography (CT) scan ≤30 days, followed by annual imaging. We sought to describe long-term adherence to surveillance guidelines among United States Medicare beneficiaries and determine patient and hospital factors associated with incomplete surveillance. METHODS: We analyzed fee-for-service Medicare claims for patients receiving EVAR from 2002 to 2005 and collected all relevant postoperative imaging through 2011. Additional data included patient comorbidities and demographics, y

Abdominal aortography remains the gold standard to evaluate patients with aneurysms for surgery. This technique helps document the extent of the aneurysms, especially their upper and lower limits. It also helps show the extent of associated athereosclerotic vascular dise …
