BACKGROUND: The study aim was to analyze the authors' experience with aortic root surgery in Marfan syndrome (MFS), and to expand the surgical outcome data of patients meeting the Ghent criteria (Marfan registry). METHODS: Analyses were performed of data acquired from MFS patients (who met the Ghent criteria), including an aortic root surgery and Kaplan-Meier survival. RESULTS: Between April 2004 and February 2012, a total of 59 MFS patients (mean age at surgery 36 ± 13 years) underwent 67 operations for aortic root aneurysm (n = 52), aortic valve (AV) regurgitation (n = 15), acute aortic dissection (n = 2), and/or mitral valve (MV) regurgitation resulting from MV prolapse (n = 7)...

Transcaval aortic access has been used for deployment of transcatheter aortic valves in patients in whom conventional arterial approaches are not feasible. This access can be vital in other situation when large bore access is needed. We described a case of 65-year-old man who had large thoracic descending aortic aneurysm with diffuse bilateral iliac disease precluding the arterial access required for the procedure. The patient underwent successful transcaval access with placement of 22-Fr balloon expandable sheath followed with successful deployments of 32 mm × 32 mm × 150 mm Valiant stent graft (Medtronic, Minneapolis, MN)...

A 58-year-old man with a long R-P' narrow QRS tachycardia underwent an electrophysiological study. The tachycardia was diagnosed as permanent form of junctional reciprocating tachycardia (PJRT), and the earliest atrial activation site during tachycardia was coronary sinus (CS) ostium. Radiofrequency ablation at the site was initially not successful because the tip impedance and temperature were unstable. After changing of the ablation catheter to that with contact force sensor, the accessory pathway was immediately ablated and the PJRT was no longer induced...

Spontaneous rupture of the aorta through an atherosclerotic lesion without preexisting aortic aneurysm, dissection, or history of trauma is very rare. Without prompt aortic repair, all cases result in sudden death with a definitive diagnosis made only intraoperatively or during autopsy. The phenomenon has been uniformly found in individuals with hypertension. The author reports a sudden unexpected death caused by spontaneous rupture of the ascending aorta in a 57-year-old man with a history of hypertension...

BACKGROUND: Aneurysms at the origin of the posterior communicating artery (PcommA) have been demonstrated to be effectively treated with the pipeline embolization device (PED). Much less is known about the efficacy of the PED for aneurysms associated with a fetal posterior cerebral artery (fPCA) variant. OBJECTIVE: To study PED treatment efficacy of PcommA aneurysms, including fPCA aneurysms. METHODS: A prospectively maintained university database of aneurysm patients treated with the PED was retrospectively reviewed...

BACKGROUND: The benefit of surgical treatment of ruptured aneurysms is well established. OBJECTIVE: To determine whether ultra-early ruptured aneurysm treatment leads to not only improved outcomes but also reduced hospitalization cost. METHODS: Using 2008-2011 Nationwide Inpatient Sample data, we analyzed demographic, clinical, and hospital factors for nontraumatic subarachnoid hemorrhage (SAH) patients who were "directly" admitted to the treating hospital where they underwent intervention (clipping/coiling)...

Background. The ideal management of SAH patients with negative initial DSA findings remains unresolved. Objective. (i) To present risk factors, clinical courses, and outcomes in different types of SAH patients with negative DSA findings; (ii) to explore the differences of basal vein between aSAH patients and NASAH patients; and (iii) to evaluate the value of repeated DSA for these patients. Methods. All SAH patients with negative initial DSA findings between 2013 and 2015 in our hospital were enrolled and were further categorized as perimesencephalic SAH (PMN-SAH) or nonperimesencephalic SAH (nPMN-SAH)...

Graft infection following aortic aneurysms repair is an uncommon but devastating complication; its incidence ranges from <1% to 6% (mean 4%), with an associated perioperative and overall mortality of 12% and 17.5-20%, respectively. The most common causative organisms are Staphylococcus aureus and Escherichia coli; causative bacteria typically arise from the skin or gastrointestinal tract. The pathogenetic mechanisms of aortic graft infections are mainly breaks in sterile technique during its implantation, superinfection during bacteremia from a variety of sources, severe intraperitoneal or retroperitoneal inflammation, inoculation of bacteria during postoperative percutaneous interventions to manage various types of endoleaks, and external injury of the vascular graft...

BACKGROUND: Multiple distal anterior cerebral artery (DACA) aneurysms appear as rare findings. Simultaneous treatment of such lesions can be particularly challenging. A report of three aneurysms on the same parent artery has not been reported before. We report a case of three DACA aneurysms treated within one microsurgical operation in a patient with eight aneurysms. CASE DESCRIPTION: A 62-year-old woman incidentally presented with multiple various size saccular aneurysms, including tree on the left DACA...

Aortic aneurysms (AA) are often asymptomatic before the occurrence of acute, potentially fatal complications including dissection and/or rupture. Beyond aortic size, the ability to assess aortic wall characteristics and processes contributing to aneurysm development may allow improved selection of patients who may benefit from prophylactic surgical intervention. Current risk stratification for aneurysms relies upon routine noninvasive imaging of aortic size without assessing the underlying pathophysiologic processes, including features such as inflammation, which may be associated with aneurysm development and progression...

Endovascular aortic aneurysm repairs rely heavily on radiologic imaging modalities for preoperative surveillance, intraoperative management, and postoperative follow-up. Ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI) and angiography all have utility at different stages of management. Often one imaging modality compliments another by providing supplementary information. Data from the imaging exams must be synthesized into one coherent plan for managing patients with aortic aneurysms...

BACKGROUND: Standard cine-cardiac magnetic resonance (CMR) imaging is commonly used to evaluate cardiac structure, geometry and function. Prior studies have shown that automated segmentation via partial voxel interpolation (PVI) accurately quantifies phantom-based cardiac chamber volumes and necropsy left ventricular myocardial mass. Despite this, the applicability and usefulness of PVI in the determination of physiologic parameters of the aorta such as aortic stiffness has yet to be investigated...

An intracranial aneurysm (IA) is a cerebrovascular pathology that can lead to death or disability if ruptured. Abnormal wall shear stress (WSS) has been associated with IA growth and rupture, but little is known about the underlying flow physics related to rupture-prone IAs. Previous studies, based on analysis of a few aneurysms or partial views of three-dimensional vortex structures, suggest that rupture is associated with complex vortical flow inside IAs. To further elucidate the relevance of vortical flow in aneurysm pathophysiology, we studied 204 patient IAs (56 ruptured and 148 unruptured)...

Background: Moderate hyperhomocysteinemia is an attractive target for intervention because it is present in 5-7% of the population and can be reversed by diet. This approach presupposes that hyperhomocysteinemia is directly involved in the disease process. Epidemiologic studies have indicated that moderately elevated homocysteine may contribute to thoracic aortic aneurysm (TAA) dilatation and dissection in humans. In vitro, elevated homocysteine disrupts the structure and function of extracellular matrix components, suggesting that moderate hyperhomocysteinemia may contribute to the development and/or progression of TAA...

Endocardial mapping of the left ventricle (LV) using the NOGA® XP Cardiac Navigation System can identify chronically ischemic and viable myocardium in patients with coronary artery disease by generating electromechanical maps. These maps are very useful when targeting myocardial tissue for injection of stem cells. We present the case of a woman who developed a perforation at the site of an LV aneurysm during NOGA mapping prior to the transendocardial injection of stem cells, as part of a multicenter clinical trial...
