OBJECTIVES: This study sought to ascertain whether patients with a bicuspid aortic valve (BAV) have an intrinsic alteration in regional aortic stiffness compared with patients with tricuspid aortic valve (TAV) and Marfan syndrome (MFS) patients with similar aortic sizes, as well as to assess the influence of ascending aorta (AAo) dilation on regional stiffness parameters in BAV patients. BACKGROUND: Imaging biomarkers as predictors of BAV, MFS, and degenerative AAo aneurysms in TAV patients (DA-TAV) are lacking...

TEVAR is a well-stablished treatment of descending thoracic aneurysms and increasingly complex endovascular procedures are being performed including aortic arch and ascending aorta. However, follow-up complications may be expected, which will enhance the need of alternative approaches such as transapical, in case of complex anatomies and reinterventions. We report the case of a man with prior history of ischemic cardiopathy and multiple endovascular aortic interventions with proximal landing in zone 1 and distal landing proximal to celiac trunk...

BACKGROUND: Mycotic aneurysm of the thoracic or thoracoabdominal aorta and infection of thoracic or thoracoabdominal aortic grafts are challenging problems with high mortality. In-situ reconstruction with cryopreserved allograft(CPA) avoids placement of prosthetic material in an infected field and avoids suppressive antibiotics or autologous tissue coverage. METHODS: Fifty consecutive patients with infection of a thoracic or thoracoabdominal aortic graft or mycotic aneurysm underwent resection and replacement with CPA from 2006 to 2016...

The patient was a 66 year-old male. Computed tomography (CT) angiography showed a huge aneurysm(120 mm) in the aortic arch and chronic type B aortic dissection(45 mm) in the descending aorta. Echocardiography showed patent ductus arteriosus( PDA). Because of pulmonary hypertension due to PDA, it was considered unacceptable to put him under general anesthesia twice. We performed thoracic endovascular aortic repair (TEVAR) via the ascending aorta and total arch replacement (TAR) simultaneously to prevent paraplegia...

Approximately one-third of patients suffering from aortic insufficiency (AI) present also with an ascending aortic aneurysm. AI is most commonly due to a combination of sinotubular junction and annular dilatation. Valve reimplantation or prosthetic valve replacement may not be ideal for these patients, and ascending aortic aneurysm resection with aortic valve repair using geometric internal ring annuloplasty is a simple, successful, and reproducible alternative treatment approach. In this video tutorial we demonstrate aortic valve repair using the HAART 300 annuloplasty ring with concomitant ascending aorta replacement...

A significant proportion of patients undergoing aortic valve replacement have a dilated ascending aorta; presence of an ascending aorta aneurysm is viewed as a contraindication for sutureless valve implantation for the potential risk of prosthesis dislodgment. We describe our technique of sutureless prosthesis implantation and concomitant ascending aorta replacement through an upper ministernotomy. Seven patients underwent aortic valve replacement with a sutureless prosthesis and concomitant ascending aorta replacement between November 2014 and October 2016...

Heat shock proteins (HSP) play an important role in the cellular adaptation to stress, a requisite for cell survival. The aortic wall appears to be a target for increased expression of HSP during surgical stress. We aimed to define the expression and function of aortic HSP70 in 31 patients with normal ascending thoracic aortic diameter who underwent aortic valve replacement due to aortic valve stenosis (AVS) and in 35 patients with dilated ascending thoracic aorta who underwent replacement of an ascending thoracic aortic aneurysm (ATAA)...

Complex adult coarctations associated with arch hypoplasia and aneurysms require a range of surgical approaches depending upon anatomy. Extra-anatomic bypass is an important strategy that enables the surgeon to avoid the risks of extensive dissection/mobilization. Extra-anatomic bypass can be accomplished from the ascending to lower descending thoracic aorta via an intra-pericardial route lateral to the right atrium and posterior to the IVC; however, this approach incompletely addresses post-stenotic aneurysmal disease...

BACKGROUND: Deep hypothermic circulatory arrest (DHCA) is often avoided in patients with concomitant ascending aortic pathology when treating other cardiac disease to avoid increased risk of morbidity and mortality. We hypothesized that the use of DHCA with retrograde cerebral perfusion (RCP) does not add incremental risk to ascending aortic replacement alone in the setting of concomitant cardiac surgery. METHODS: 408 ascending aortic ± hemiarch replacements and aortic (root)/mitral/tricuspid valve(s), CABG, or MAZE procedures were performed for concomitant cardiac disease...

Prosthetic valve infective endocarditis (IE) is one of the most serious postimplantation complications. Prosthetic aortic valve IE constitutes 1%-6% of all prosthetic valve IE cases. We present a dramatic echocardiographic case of prosthetic aortic valve IE leading to near-complete valve dehiscence. Echocardiographic evidence of prosthetic aortic valve rocking motion is indicative of significant dehiscence. Aside from IE, other causes and risk factors for prosthetic aortic valve dehiscence include inflammatory and autoimmune vasculitides, concomitant ascending aorta aneurysm, and aortic root calcification...

INTRODUCTION: Thoracic endovascular aortic aneurysm repair (TEVAR) is an established treatment for thoracic aortic disease in both the acute and elective setting, with such a widespread use that almost 50% of all thoracic aortic surgery in Europe is performed by these means. Nonetheless, the feasibility of TEVAR is determined by several anatomic factors, and the suitability of the proximal and distal landing zones remain one of the main limitations to its use. The advent of custom-made thoracic stent grafts widened the endovascular options in some challenging anatomies...

INTRODUCTION: Cardiovascular syphilis can manifest as aortic aneurysms, aortic regurgitation and coronary ostial stenosis. Tertiary syphilis was the most commom reported cause of thoracic aortic aneurysm in the pre-antibiotic era, contributing to 5- 10% of cardiovascular deaths. However, in the 21st century, it has virtually disappered from the devoloping nations. Tertiay syphilis may develop in about one third of cases of untreated syphilis. In the pre-penicilin era, it was calculated that cardiovascular syphilis was responsible for 10-15% of clinical syphilis...

INTRODUCTION: Classical conventional surgery to treat multi-segmental thoracic aortic disease in two operative stages, sternotomy and left thoracotomy, is associated with significant mortality and complications. The Frozen Elephant Trunk (FET) associated with an endovascular procedure (TEVAR) allows an extensible and simplified surgical approach of the descending and thoracoabdominal aorta without increasing the risk. METHODS: Retrospective study of 8 patients (pts), 5 males, mean age 67...

INTRODUCTION: Current guidelines suggest that patients with aortic diameter over 55-60 mm should undergo ascending aorta replacement, depending on associated valve pathology and other comorbidities. Studies show that the risk of aortic rupture over 60 mm is over 30%. Even though, we still receive in our practice patients that present with aneurysms of greater dimensions. The aim of our study is to evaluate the surgical outcomes of patients presenting with ascending aorta with diameter larger than 70 mm...

INTRODUCTION: Older age is often regarded as a relative contraindication for open surgery for aortic aneurysms. These individuals often have a greater comorbidity burden that predispose them for development of postoperative complications. The aim of our study is to evaluate the surgical outcomes of selected octogenarians after open aortic surgery. METHODS: We performed a retrospective observational study. We collected data from patients operated on by our team between January of 2012 to September of 2017...

INTRODUCTION: Surgical approach of multisegmental pathology of the thoracic aorta, namely aortic arch / descending aorta is challenging. The Frozen Elephant Trunk (FET) has good results, with acceptable risk. However, in the subgroup of patients (pts) older than 75 years and with important comorbidities, the surgical risk is very high.

INTRODUCTION: The Frozen Elephant Trunk (FET) surgery allows correction of ascending, arch and proximal descending aortic pathology, using a hybrid prosthesis at the same time. It is a complex intervention and requires a multidisciplinary team that, besides scheduling and performing the surgery, accompanies the patient (pt) throughout the postoperative period. OBJECTIVES: To review short and medium term clinical results with this technique. METHODS: Between January 2010 and September 2017, we operated 34 patients (pts) using FET...

BACKGROUND: Recent guidelines support more aggressive surgery for aneurysms of the ascending aorta and root in patients with bicuspid aortic valve. However, the fate of the arch after surgery of the root and ascending aorta is unknown. We set out to assess outcomes following root and ascending aortic surgery and subsequent growth of the arch. METHODS: Between 2005 and 2016, 536 consecutive patients underwent surgery for aneurysm of the root and ascending aorta. 168 had bicuspid aortic valve...

The most tried out, 'classical' technique of the operation in acute type A aortic dissection is supracoronary prosthetic repair of the ascending aorta and proximal portion of the aortic arch, as the simplest and fastest intervention. However, this technique is associated with late complications related primarily to formation of a persistent false lumen leading to formation of an aneurysm of the descending aorta. Total prosthetic repair of the aortic arch, including the 'frozen elephant trunk' technique, contributes to thrombosis of the false lumen and remodelling of the thoracic aorta...
