Background: The diagnostic performance of SPECT-only imaging for takotsubo cardiomyopathy (TC) is limited due to the lack of coronary artery distribution information. The aim of this study was to evaluate the diagnostic performance of hybrid cardiac SPECT/CT for patients with TC or acute coronary syndrome (ACS). Methods: Twenty-two patients with apical ballooning left ventricular (LV) dysfunction who underwent cardiac perfusion SPECT using 99m Tc-methoxy-isobutyl-isonitrile (MIBI), cardiac fatty-acid metabolism SPECT using 123 I-beta-methyl-P-iodophenyl-pentadecanoic acid (BMIPP), cardiac CT, and hybrid cardiac SPECT/CT imaging were analyzed...

Background Chronic rhinosinusitis (CRS) is a devastating disease affecting nearly 30 million people in the United States. An interim analysis of data from the present study suggested that, in patients who had previously failed medical therapy, balloon sinus dilation (BSD) plus medical management (MM) provides a significant improvement in the quality of life (QOL) at 24 weeks postprocedure compared to MM alone. Objective The primary objective of this final analysis was to evaluate the durability of treatment effects through the 52-week follow-up...

Crohn's disease (CD) and ulcerative colitis (UC) constitute the two most common phenotypes of inflammatory bowel disease (IBD). Ileocolonoscopy with biopsy has been considered the gold standard for the diagnosis of IBD. Differential diagnosis of CD and UC is important, as their medical and surgical treatment modalities and prognoses can be different. However, approximately 15% of patients with IBD are misdiagnosed as IBD unclassified due to the lack of diagnostic certainty of CD or UC. Recently, there has been increased recognition of the role of the therapeutic endoscopist in the field of IBD...

Peutz-Jeghers syndrome is an autosomal dominant disorder with multiple hamartomatous polyps throughout the gastrointestinal tract. The clinical history of patients with Peutz-Jeghers syndrome usually includes multiple laparotomies to treat intestinal obstruction caused by polyps. The development of double-balloon enteroscopy enables endoscopic resection of polyps, even in the distal small intestine. This article is protected by copyright. All rights reserved.

BACKGROUND: Treatment for fractures of the tibial plateau is in most cases carried out by stable fixation in order to allow early mobilization. Minimally invasive technologies such as tibioplasty or stabilization by locking plate, bone augmentation and cement filling (CF) have recently been used to treat this type of fracture. The aim of this paper was to determine the mechanical behavior of the tibial plateau by numerically modeling and by quantifying the mechanical effects on the tibia mechanical properties from injury healing...

Budd-Chiari syndrome (BCS) is a rare but life-threatening disease. If not treated promptly, it is almost always lethal of progressive liver failure, severe nutritional depletion, and renal failure at the late stage. We report the successful treatment of a 5-year-old boy with BCS due to a stenosis of the IVC with a 26-year follow-up. We performed percutaneous transluminal angioplasty (PTA), which resulted in a great improvement of BCS, and the disappearance of ascites. Restenosis occurred at 25 years after the initial angioplasty, for which balloon angioplasty was repeatedly performed...

OBJECTIVE: Iliac vein stenting is increasingly being used in the treatment of venous insufficiency for patients with nonthrombotic iliac vein lesions (NIVL). We have noticed that many stents do not deploy to the expected stent area as designated by the manufactured diameter. The purpose of this study was to evaluate the dynamics of Wallstent® expansion in the iliocaval system. METHODS: Retrospective analysis of all patients with NIVL who were treated with iliac vein stenting using Wallstents®...

Aortoiliac occlusive disease (AOID) results in varying degrees of pelvic and lower extremity arterial insufficiency. Treatment approach has evolved and endovascular therapies are being successfully reported for high-grade lesion. However, Trans Atlantic Inter-Society Consensus (TASC) D often necessitates open revascularization. Disease limited to the infrarenal segment does not typically affect intestinal perfusion in the absence of visceral aortic or mesenteric vessel involvement. Chronic mesenteric ischemia most commonly occurs due to atherosclerotic disease of two or three of the mesenteric vessels...

The treatment of coronary bifurcations is challenging for interventional cardiologists. The Tryton stent (Tryton Medical, Inc., USA) is one of the few devices specifically designed for coronary bifurcations that underwent large clinical trials. Although the manufacturer provides specific recommendations to position the stent in the bifurcation side branch (SB) according to four radio-opaque markers under angiographic guidance, wrong device positioning may accidentally occur. In this study, the virtual bench testing approach was used to investigate the impact of wrong positioning of the Tryton stent in coronary bifurcations in terms of geometrical and biomechanical criteria...

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is a method widely used to support circulation in patients with fulminant myocarditis (FM). However, a common complication associated with ECMO is left ventricular (LV) overload. METHODS: This case series observed the effects of intra-aortic balloon pump (IABP) and beta-blockers for the treatment of LV overload after ECMO. The cases of eight patients with FM who underwent ECMO from September 2009 to July 2016 were reviewed...

For neonates with right atrial isomerism (RAI), functional single ventricle (f-SV), and obstructive total anomalous pulmonary venous connection (TAPVC), primary TAPVC repair (TAPVCR) has a poor outcome. At our hospital, the survival rate at 1 year of such neonates undergoing primary TAPVCR between 1999 and 2010 (TAPVCR group) was 30% (3/10). Most deceased cases suffered from capillary leak syndrome and unstable pulmonary resistance after the surgeries. We sought to determine whether less invasive primary draining vein stenting (DVS) improved the outcome of these neonates...

Transcatheter mitral valve implantation (TMVI) has been performed in high-risk and inoperable patients for degenerated mitral bioprostheses (TMVIinV) and failed annuloplasty rings (TMVIinR). TMVIinR is more challenging compared to TMVIinV because of the differences in dimensions, shapes, and contours between rings and valves. In this report, we present two clinical cases of TMVIinR that were treated by trans-septal implantation of a balloon-expandable prosthesis. In TMVI cases with an incomplete ring, the ring will be stretched out toward its anterior and commissural side, and the open side of the ring will increase in width...
