Critical limb ischemia (CLI) represents the terminal stage of peripheral arterial disease (PAD) and is characterized by multilevel and multivessel disease. Amongst patients with infrainguinal disease, approximately one third have predominantly isolated infrapopliteal disease and the remaining two thirds, a combination of femoropopliteal and infrapopliteal disease. Isolated infrapopliteal disease is mainly seen in the elderly, diabetic, or dialysis-dependent patients. These patients have higher risk of amputation and shorter amputation-free survival...

OBJECTIVE: When a bypass fails, the options are lysis, redo bypass, or endovascular intervention. If lysis of the original bypass is not considered an option, which is better-redo bypass or attempts at endovascular recanalization of the native system? This retrospective study examined the outcomes of native superficial femoral artery (SFA) chronic total occlusion (CTO) recanalization compared with redo bypass after failed femoropopliteal bypass. METHODS: Patients presenting with a symptomatic failed femoropopliteal bypass that underwent attempted CTO endovascular (EV) recanalization of the native SFA or a redo femoropopliteal bypass (BP) from 2000 to 2015 were analyzed...

BACKGROUND: Successful chronic total occlusion (CTO) revascularization has been associated with prognostic benefits. Whether the extent of coronary artery disease interferes with these benefits has not been investigated yet. AIMS: We sought to compare the survival after percutaneous coronary intervention (PCI) for CTO between patients with multi- (MVD) and single-vessel disease (SVD). METHODS: A total of 2002 consecutive patients undergoing CTO PCI between 01/2005 and 12/2013 were identified and stratified according to the presence/absence of MVD...

In minimal invasive cardiac surgery (MICS), the surgeon is missing haptic feedback of the guide wire for navigation through the vessels. A wide range of guide wires with various properties and performance characteristics are available to reduce the risk of complications during the intervention. This paper presents a force sensing guide wire for cardiac catheterization, which provides the surgeon a haptic feedback on the guide wire tip. Three conventional wires for the recanalization of chronic total coronary occlusions (CTO) are investigated and general design requirements for the force sensing guide wire are determined...

Inability to cross the lesion with a guidewire is the most common reason for failure in percutaneous revascularization (PCI) of chronic total occlusions (CTOs). An ostial or stumpless CTO is an acknowledged challenge for CTO recanalization due to difficulty in successful wiring. IVUS imaging provides the opportunity to visualize the occluded vessel and to aid guidewire advancement. We review the value of this technique in a single-centre experience of CTO PCI. This series involves 22 patients who underwent CTO-PCI using IVUS guidance for stumpless CTO wiring at our institution...

BACKGROUND: Although studies have demonstrated comparable efficacy and safety profiles of everolimus- and zotarolimus-eluting stents (EES and ZES, respectively) for a broad spectrum of coronary artery diseases, there is paucity of data concerning their safety and efficacy for coronary chronic total occlusions (CTOs). This study compared the clinical performance of EES and ZES following successful percutaneous coronary intervention for CTOs. METHODS: The cohort included 539 consecutive CTO patients who underwent successful PCI using EES (n=313) and ZES (n=226) between September 2006 and August 2014...

Primary percutaneous coronary intervention (PCI) is the treatment modality of choice in patients presenting with ST elevation myocardial infarction (STEMI). Clinical outcomes have dramatically improved with the wide adoption of primary PCI in patients with STEMI because of acute thrombotic native coronary artery occlusion. However, patients with prior coronary artery bypass graft (CABG) surgery who present with STEMI because of acute saphenous vein graft (SVG) occlusion continue to have worse outcomes because of poor acute and long-term results of SVG stenting...

BACKGROUND: Morbid obesity is a state of insulin resistance combined with excess of visceral fat, which contributes to the development of metabolic syndrome (MetS). Nonsurgical treatment of obesity usually improves MetS, but there is no ultimate resolution and weight regain is common. Surgical options like Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) result in a significant and sustained weight loss accompanied by improvement of MetS. The aim of this study was to compare the weight loss and improvement of MetS parameters between degree II and III obese patients with MetS undergoing RYGB or SG in a period of 12 months...

BACKGROUND: The optimal strategy to manage chronic total occlusion (CTO) remains unclear. The Japanese CTO multicenter registry (J-CTO) score is an established tool for predicting successful recanalization. However, it does not take into account nonangiographic predictors for final technique success. In the present study, we designed and tested a scoring model called the Busan single-center CTO registry (B-CTO) score combining clinical and angiographic characteristics to predict successful CTO recanalization in Korean patients...
