OBJECTIVES: To evaluate the fate of a dissected aortic arch after limited surgical repair type A dissection. METHODS: Of 271 patients operated for acute dissection between 2001 and 2015, 86 (age 57 ± 13 years, 74% men) with predischarge computed tomographic (CT) scans had residual in arch. Aortic diameters, lengths, ellipticity communications lumina were assessed using follow-up CT scans. The median scan was 31 months (first quartile 15, third 52). RESULTS: largest increase total diameter at...

The aim of this study was to investigate the accuracy stent graft deployment in distal landing zone (LZ) during thoracic endovascular aortic repair (TEVAR). Currently, TEVAR focuses on accurate proximal LZ. Data LZ are lacking.Of 195 patients (2005-16) with a non-dissected pathology, 59 [median age 73 years (first quartile 68; third 77), 20 women] had shorter than 40 mm. In all, deploy just above target vessel (coeliac trunk, mesenteric superior or renal artery). Patients were divided into...

The stress in the ascending aorta results from many biomechanical factors including geometry of vessel and its maximum dimensions, arterial blood pressure longitudinal systolic stretching due to heart motion. resulting displacement aortic annulus during cycle has not been examined general population so far. aim study is evaluate this parameter using cardiovascular magnetic resonance (CMR) imaging all age groups.The cardiac images 73 patients were evaluated. distance which ventriculo-aortic...

Biomechanical factors influence stress in the aortic wall. The aim of this study was to assess how diameter and shape vessel, blood pressure longitudinal systolic stretching (SAS) caused by contraction myocardium Three computational models non-dilated aorta aneurysms ascending root were created. Then, finite elements analyses carried out. subjected (120 mmHg 160 mmHg) (0 mm, 5 10 mm 15 mm). wall elasticity examined too. Blood had a smaller impact on than SAS. An increase from 120 increased...

Coronary artery bypass graft (CABG) surgery is an effective therapeutic strategy for coronary heart disease (CHD). Myocardial longitudinal strain echocardiography with 2D speckle tracking could obtain ventricular function better accuracy and reliability than the left ejection fraction. The aim of study was to assess changes in patients before after surgical revascularization a 24-month period observation, using imaging. We searched echocardiographic predictors poor early long-term outcome...

External wrapping is a surgical method performed to prevent the dilatation of aorta and decrease risk its dissection rupture. However, it also believed cause degeneration aortic wall. A biomechanical analysis was thus assess stress wall subjected external wrapping.A using finite elements carried out on three models: non-dilated aorta, moderately dilated wrapped aorta. The models were pulsatile flow (120/80 mmHg) systolic annulus motion 11 mm.The showed that exerted outer surface ascending in...

Background There is evidence that advanced infectious chronic periodontal inflammatory disease may have an impact on general health including cardiovascular diseases. The aim of this clinical study was to evaluate the ability Porphyromonas gingivalis colonize heart valves and, subsequently, assess whether there association between presence DNA in pockets and degenerated valves.Materials Methods Thirty patients were enrolled 31 valve specimens harvested during cardiac surgery operations...

The risk of aortic dissection should be assessed based not only on the diameter, but also other biomechanical parameters that have an impact stress in wall. This study evaluates very rare clinical scenarios patients with both pre- and post-dissection computed tomography (CT) images whether increased wall correlates localization intimal entry tear Type A dissection. CT-angiography 4 performed shortly prior to after developing were evaluated. distribution pre-dissection aortas was evaluated...

Acute aortic dissection leads to the destabilization of wall, followed by an immediate increase in diameter. It remains unclear how diameter changes during dissection's acute and subacute phases. The aim this study was evaluate change geometry within 30 days after onset a descending dissection.Patients with type B non-A non-B who had at least 2 computed tomography angiography scans obtained were evaluated. Exclusion criteria thrombosed false lumen, connective tissue disorders endovascular or...

External wrapping is a surgical technique used in patients with dilated ascending aorta. To date, there no available data describing the radiographic features of aorta subjected to external using straight corrugated Dacron vascular prosthesis. The aim this study was find distinctive an externally constricted aorta.Preoperative and early postoperative (7th day) CT angiography images ten who underwent procedures were assessed compared. analyzed order characteristic wrapping.The CT-angiography...

Large aortic diameter is considered the most frequent cause of dissection. However, this assumption relies on postdissection imaging aorta. We recently showed that acute dissection leads to a 23% increase in descending diameter. Our aim was model aorta before occurred.Between 2003 and 2017, total 190 patients developed In total, 165 non-Marfan were included, whose computed tomography angiography scans available taken within 6 h after occurrence [67 (first quartile 58-third 75) years, 69%...

Longitudinal stretching of the aorta due to systolic heart motion contributes stress in wall ascending aorta. The objective this study was assess longitudinal and its correlation with diameters aortic root.Aortographies 122 patients were analyzed. caused by contraction during systole maximum dimensions root measured all patients.The dimension on average 34.9 ±4.5 mm mean diameter 33.9 ±5.4 mm. negatively correlated age (r = -0.49, p < 0.001) tubular -0.44, 0.001). There no significant...

External wrapping is a surgical technique performed in patients with dilated ascending aorta. The aim of this study to present the mid-term results aorta.34 (mean age: 64.4 ± 10.8 years, 21 males) aorta were operated on at single cardiac surgery center using technique. aortas wrapped 32-36 mm straight Dacron vascular prostheses. aortic wall was not excised any patients. Wrapping concomitant other procedures 30 (88 %), which involved valve 28 (82 %).The mean follow-up time 19.5 8.3 months...

The incompetent bicuspid aortic valve (BAV) can be repaired using various techniques. This study presents a prospective comparison of external and subcommissural annuloplasty.Fifty consecutive patients (38 males, age: 43.9 ± 15.8 years) with BAV insufficiency or without dilatation underwent repair in single institution. They were prospectively allocated to one two groups based on the annulus stabilization technique: 25 operated annuloplasty (SCA) complete (EA). Transthoracic echocardiography...

Background. Chronic limb ischemia is a serious clinical problem. Patients who do not qualify for standard treatment may benefit from novel gene therapies.Objectives. This study evaluated angiogenesis following intramuscular injections of angiogenic plasmid Ang-1 in Fisher rats.Material and Methods.

Background: The rotational position of the aortic root (AoR) is substantial clinical interest as it has been associated with severe complications, such dissections. We described a cardiac magnetic resonance (CMR)-based method for measuring AoR rotation and evaluated reliability measurements. Methods: CMR was used in 50 consecutive healthy subjects. Intra- interobserver were assessed by comparing repeated measurements same analyst three independent analysts. angles non-coronary sinus (NCS),...

Mediastinal adipose tissue can be found on the anterior surface of pericardial sac below remnants thymus. On basis previous studies describing adenoviruses (AdVs) as a causative factor obesity, relation between presence AdVs and an increased accumulation mediastinal was studied. The study included 25 obese/overweight subjects with cardiac disorders. Specimens from fat deposits mediastinum were collected during surgery procedures. Afterwards, PCR used to detect AdV-DNA. No AdV-DNA could...
