INTRODUCTION: Late open surgical conversion following endovascular aneurysm repair (EVAR) may occur more frequently after performing EVAR in anatomy outside the instructions for use (IFU). This study reviews predictors and outcomes of late open surgical conversion for failed EVAR. METHODS: This retrospective cohort study reviewed all EVARs performed at the Ottawa Hospital between January 1999 and May 2015. Open surgical conversions >1 month post EVAR were identified...

Chimney EVAR (CHEVAR) and Fenestrated EVAR (FEVAR) are two options for management of very complex abdominal aortic aneurysm (AAA). While some anatomical factors may favor one strategy over the other, there are some cases where the anatomical challenges may require using a hybrid approach. We are reporting the case of an 84-year-old male with a 6.8×5.7cm infrarenal abdominal aortic aneurysm that arises immediately below the level of the renal arteries and extends down to just above the iliac bifurcation with occluded celiac and inferior mesenteric arteries and severe bilateral renal artery stenosis with caudally oriented right renal and cranially oriented left renal artery...

OBJECTIVES: Transcatheter approaches in heart valve disease became tremendously important and are currently established in the aortic position, but transcatheter tricuspid repair is still in its beginning and remains challenging. Replicating the surgical edge-to-edge technique, for example, with the MitraClip System (Abbott Vascular, Santa Clara, Calif), represents a promising option and has been reported successfully in small numbers of cases. However, up to now, few data considering the edge-to-edge technique as a transcatheter approach are available...

OBJECTIVE: To report the learning curve and early results of robotic mitral valve repairs in comparison with propensity score-matched sternotomy controls after the adoption of a robotic mitral valve surgery program in a university teaching hospital. METHODS: A total of 142 patients underwent robotic mitral valve repair due to degenerative mitral regurgitation between May 2011 and December 2015. Control patients operated on via the conventional sternotomy approach were selected by the use of propensity score analysis resulting in 2 well-matched study groups...

OBJECTIVE: The lack of annular stabilization is the drawback of aortic root remodeling, and recently the addition of annuloplasty has been proposed. Limited data, however, exist on late annular size after remodeling. We studied annular size over time. METHODS: In 241 patients (53 ± 16 years) annular size was determined preoperatively (T0), before discharge (T1), and at least 2 years after remodeling (T2, 54 ± 27 months) with (n = 52) or without external suture annuloplasty...

Background: Whether primary tear size impacts extent of type A dissection is unclear. Using statistical groupings based on dissection morphology, we examined its relationship to primary tear area. Methods: We retrospectively reviewed 108 patients who underwent acute ascending dissection repair from 2000-2016. Dissection morphology was characterized using 3-dimensional (3D) reconstructions of computed tomography (CT) scan images. Two-step cluster analysis was performed to group the dissections by examining the true lumen area as a fraction of the total aortic area at various levels...

OBJECTIVE: Early data suggest that FEVAR is feasible but may have higher morbidity and unclear durability compared to open surgical repair (OSR) of complex abdominal aortic aneurysms (CAAA). We compared the early experience following elective FEVAR to traditional OSR of CAAA in a high-volume open aortic center. METHODS: All patients undergoing FEVAR and OSR for elective CAAA from 1/2010-7/2015 were identified. Univariate, multivariable logistic, and Cox hazards modeling were used to compare perioperative and intermediate outcomes...

OBJECTIVES: Uncomplicated type B dissections have historically been treated medically with hemodynamic control. Early progression of the disease and late aneurysmal dilation have been considered as indications for intervention. The aim of this study is to analyze growth rate patterns of type B dissections based on Computed Tomography measurements over time. METHODS: We conducted a retrospective review of patients with acute type B dissection from 2008 to 2014 who had at least two follow up CT scans...

PURPOSE: To evaluate the diagnostic accuracy of diameter measurements for the detection of aneurysm volume increase during follow-up after endovascular aortic repair (EVAR) of abdominal aortic aneurysms (AAAs). MATERIALS AND METHODS: This retrospective study analyzed 100 pairs of follow-up computed tomography scans randomly selected from an EVAR database (male/female ratio, 91/9; mean age, 71 y; bifurcated and aortouniiliac stent grafts, 96% and 4%, respectively; mean interval, 359 d)...

BACKGROUND: A modified technique for frozen elephant trunk (FET) repair of acute DeBakey type I dissection has evolved. Procedural modifications are described and midterm outcomes evaluated. METHODS: From 2009 to 2016, 72 patients with DeBakey type I dissection underwent emergency simplified FET. Mean age was 59 ± 15 years. Presentation included malperfusion (n = 22, 31%), rupture (n = 12, 16%), and aortic insufficiency (n = 42, 58%). Concomitant procedures included valve replacement (n = 9), root replacement (n = 11; valve sparing n = 6), cusp repair (n = 11), and valve resuspension (n = 21)...

BACKGROUND AND AIM: Patients presenting with type A aortic dissection (TAAD) present with a wide clinical spectrum ranging from hemodynamic stability to multiorgan malperfusion with cardiovascular collapse. Extracorporeal membrane oxygenator (ECMO) therapy is increasingly being utilized as salvage therapy in patients with acute cardiopulmonary failure and for post-cardiotomy shock. We sought to determine the utility of ECMO implementation post-TAAD repair. METHODS: The Pennsylvania Health Care Cost Containment Council (PHC4) database, maintained by an independently functioning state agency, was retrospectively reviewed from 2004 to 2014...

OBJECTIVE: To evaluate the safety and feasibility of a novel stent-graft for thoracic endovascular aortic repair (TEVAR) in a canine model, 9 adult hybrid dogs were used for the experiment. METHODS: All animals were implanted with a novel thoracic aortic stent-graft via femoral artery. Blood sample was collected at pre-operation and 1, 2, 4, 8 and 12 weeks after implantation for hematological examination. Moreover, tissues from randomly selected 4 dogs were subjected to histopathological analysis with the optical microscope after stent-grafts were implanted for 3, 6, 9, and 12 months respectively...

OBJECTIVE: The disease of the aortic arch is traditionally approached by open surgical repair requiring cardiopulmonary bypass and circulatory arrest. This study performed a retrospective analysis comparing outcomes through primary hybrid patients submitted to aortic arch surgery without cardiopulmonary bypass with patients submitted to conventional open surgery. METHODS: 25 patients submitted to the aortic arch surgery were selected in the period 2003-2012 at the Madre Teresa Hospital in the city of Belo Horizonte, Brazil; 13 of these underwent hybrid technique without cardiopulmonary bypass and 12 underwent conventional open surgery...

Arterial vasculopathy and residual aortic obstruction can lead to left ventricular (LV) dysfunction in patients with coarctation of the aorta (CoA) related to adverse ventriculo-arterial coupling. This study aimed to investigate potential differences in LV myocardial deformation indices between repaired CoA patients and healthy controls. Twenty-two CoA patients (age 30 ± 10.6 years) after surgical repair (n = 12) or balloon angioplasty (BA) (n = 10) without residual stenosis, between 3 months and 16 years of age with > 10 years follow-up were compared to 22 healthy age- and gender-matched controls (age 30 ± 3...

Thoracic endovascular repair (TEVAR) is an effective treatment for type B aortic dissection (TBAD). Here, we evaluated the early-midterm effectiveness and safety of TEVAR for treating TBAD patients after renal transplantation. Six patients with TBAD treated with TEVAR after renal transplantation were recruited between February 2012 and December 2016. They were then followed up with clinical examinations and computed tomography angiography (CTA). TEVAR was successfully performed in all patients (100%), and the primary tear sites were well covered by stents with or without coverage of the left subclavian artery...
