Relationship between radiation-induced skin ulceration (RSU) and variables in percutaneous coronary interventions (PCI) was rarely reported. RSU is a severe complication in PCIs, especially for chronic total occlusion (CTO) lesions. We investigated the RSUs and their risk factors in patients receiving CTO PCIs over a 2-year period. Data were analyzed using chi-square tests, t-tests and receiver operating characteristic (ROC) curve. Of 238 patients, 11 patients (4.6%) had RSUs all at right upper back. RSUs were significantly associated with use of left anterior oblique (LAO) views (100% vs...

Balloon uncrossable lesions are a well-known challenge during chronic total occlusion (CTO) interventions. The technique of using two different catheters into the same coronary artery, the so-called "ping-pong" technique, is a technique described for treating complications during percutaneous coronary intervention (PCI), like perforations or rotational atherectomy burr entrapment. We describe a case where the "ping-pong" technique was successfully used to facilitate treatment of a balloon uncrossable CTO lesion...

OBJECTIVES: This study sought to accurately describe the success rate, risks, and patient-reported benefits of contemporary chronic total occlusion (CTO) percutaneous coronary intervention (PCI). BACKGROUND: In light of the evolving techniques to successfully revascularize CTO lesions, there remains a compelling need to more accurately quantify the success rates, risks, and benefits of these complex procedures. METHODS: Using a uniquely comprehensive, core-lab adjudicated, single-arm, multicenter registry of 1,000 consecutive patients undergoing CTO PCI by the hybrid approach, we evaluated the technical success rates, complication rates, and raw and adjusted health status benefits at 1 month among successfully as compared to unsuccessfully treated patients...

We report herein the optical coherence tomography (OCT) and stent boost imaging guided bioresorbable vascular scaffold (BVS) implantation for right coronary artery (RCA) chronic total occlusion (CTO) lesion. The gold standard for evaluating BVS expansion after percutaneous coronary intervention is OCT. However, stent boost imaging is a new technique that improves fluoroscopy-based assessments of stent overlapping, and the present case shows clinical usefulness of OCT and stent boost imaging guided 'overlapping' BVS implantation via antegrade approach for a typical RCA CTO lesion...

INTRODUCTION: Coronary chronic total occlusions (CTOs) are commonly encountered during diagnostic angiograms. With recent advances, especially in experienced centers, success rates with CTO percutaneous coronary intervention (PCI) have approached 80% or higher. It is important to note that despite these advancements in techniques, CTOs remain difficult to treat. We present a case of a left circumflex artery (LCX) CTO that was successfully revascularized using a microcatheter balloon pinning technique that allowed additional wire support...

BACKGROUND: The Evaluating Xience and left ventricular function in PCI on occlusiOns afteR STEMI (EXPLORE) trial did not show a significant benefit of percutaneous coronary intervention (PCI) of the concurrent chronic total occlusion (CTO) in ST-segment elevation myocardial infarction (STEMI) patients on global left ventricular (LV) systolic function. However a possible treatment effect will be most pronounced in the CTO territory. Therefore, we aimed to study the effect of CTO PCI compared to no-CTO PCI on the recovery of regional LV function, particularly in the CTO territory...

Chronic total occlusions (CTOs) are commonly encountered in patients undergoing coronary angiography, but percutaneous coronary intervention (PCI) for CTO is currently infrequently performed owing to the perception of limited clinical benefit, high complexity and cost of intervention, and perceived risk of complications. Numerous observational studies have demonstrated that successful CTO revascularization is associated with better cardiovascular outcomes and enhanced quality of life (QOL). However, in the absence of randomized trials, its prognostic benefit remains debated...

Chronic total occlusions (CTOs) are routinely encountered during coronary angiography, but subsequent revascularization rates are low. This has likely been driven by a historical belief that there is minimal clinical benefit and poor success rates with a percutaneous coronary intervention (PCI). However, in the current era, with the development of new techniques and tools, experienced operators can perform CTO-PCI successfully in the majority of patients. The current indications and benefit of CTO-PCI remain a topic of controversy and debate...

The most important factor for preventing contrast-induced nephropathy (CIN) during percutaneous coronary intervention (PCI) in patients with severe renal dysfunction is to minimize the contrast volume. Herein, we report a successful case of complete revascularization after 3 separate PCI procedures using a super-low volume of contrast medium in a patient with 3-vessel disease, including two chronic total occlusions (CTOs). A 70-year-old man having exertional angina despite maximal medical therapy was referred to our hospital...
