Percutaneous coronary interventions (PCI) are done for a variety of indications. Data from the CathPCI Registry is highly useful to evaluate the outcomes from performing a PCI procedure in unusual circumstances, such as in cases of chronic total coronary artery occlusion, cardiogenic shock after a myocardial infarction, syncopal patients, asymptomatic patients, and before surgery that is noncardiac. Registry information is also valuable in evaluating the efficacy of coronary stents. This article summarizes some of the information available on these subjects...

BACKGROUND: Despite the increasing use of left main (LM) percutaneous coronary intervention (LM-PCI), there have been no pathological studies devoted to understanding the causes of LM stent failure. We aimed to systematically determine the pathological mechanisms of LM stent failure. METHODS AND RESULTS: From the CVPath Stent registry, a total of 46 lesions were identified to have LM-PCI. Pathologic stent failure (PSF) was defined as stent thrombosis, restenosis and in-stent chronic total occlusion (CTO)...

PURPOSE: Cardiac PET-MR has shown potential for the comprehensive assessment of coronary heart disease. However, image degradation due to physiological motion remains a challenge that could hinder the adoption of this technology in clinical practice. The purpose of this study was to validate a recently proposed respiratory motion-corrected PET-MR framework for the simultaneous visualisation of myocardial viability (18 F-FDG PET) and coronary artery anatomy (coronary MR angiography, CMRA) in patients with chronic total occlusion (CTO)...

We report a novel technique for retrieving an entrapped Gaia guidewires in severely calcified coronary chronic total occlusion (CTO) using a rotational atherectomy device. By successfully cutting the entrapped and untangled guidewire within the CTO with the use of a rotational atherectomy device, we could effectively remove the Gaia guidewire from the right coronary artery.

We recently found that renal carbonic anhydrase (CA) is involved in the reabsorption of inorganic nitrite (NO2 - ), an abundant reservoir of nitric oxide (NO) in tissues and cells. Impaired NO synthesis in the endothelium and decreased NO bioavailability in the circulation are considered major contributors to the development and progression of renal and cardiovascular diseases in different conditions including diabetes. Isolated human and bovine erythrocytic CAII and CAIV can convert nitrite to nitrous acid (HONO) and its anhydride N2 O3 which, in the presence of thiols (RSH), are further converted to S-nitrosothiols (RSNO) and NO...

Clinical manifestations of acute myocardial infarction can be more than just chest pain. Patients can present with dyspnea, fatigue, heart burn, diaphoresis, syncope, and abdominal pain to name a few. Our patient was a 74-year-old male with a past medical history of type 2 diabetes mellitus, hypertension, hyperlipidemia, and COPD due to chronic tobacco use, who presented with persistent hiccups for 4 days and no other complaints. Coincidently, he was found to have a diabetic foot ulcer with sepsis and acute kidney injury and hence was admitted to the hospital...

BACKGROUND: Patients' intra and post procedural comfort, quick recovery, as well as procedure success, are key elements for choosing the right arterial access site. Radial artery access has been of increasing interest since it was first described. Advanced treatments of coronary lesions, from primary percutaneous interventions during ST elevation myocardial infarction cases to chronic total occlusion cases, have been increasingly done through the radial access. Distal left trans radial artery (dlTRA) is a new technique first described by Kiemineij...
