First in man: percutaneous coronary angioplasty using non-fluoroscopic electro-anatomic mapping

We present a case where percutaneous coronary intervention was done successfully using an electroanatomic mapping system (NavX ™; Abbot Inc. USA); with near zero use of fluoroscopy or contrast agent.

This study aimed to investigate the severity of coronary artery disease (CAD) in patients with ATX. METHODS: A total of 394 patients with CAD undergoing percutaneous coronary intervention (PCI) at Chiba University Hospital between June 2016 and February 2018 were enrolled. Soft X-ray radiography of Achilles tendon was performed, and a maximum thickness of 9 mm or more was regarded as ATX. Heterozygous FH was diagnosed according to the diagnostic criteria proposed by the Japan Atherosclerosis Society in 2017. CAD severity was assessed by SYNTAX score before the first PCI during the study period. RESULTS: There wer...

AbstractFamilial hypercholesterolemia (FH) is reportedly associated with the development of coronary artery disease (CAD), especially acute coronary syndrome (ACS). However, the prevalence of FH in patients with stable CAD is still unclear. The aim of this study was to investigate the prevalence of Achilles tendon xanthoma (ATX) and heterozygous FH in patients with stable CAD and ACS undergoing percutaneous coronary intervention (PCI). A total of 423 patients with CAD (273 stable CAD and 150 ACS) undergoing PCI at Chiba University Hospital between June 2016 and February 2018 were enrolled in this study. Soft X-ray radiogra...

The Resolute Onyx stent was developed to improve visibility while reduc...

Rationale: Contrast-induced acute kidney injury is one of the most serious adverse effects of contrast media and is related to three distinct but interacting mechanisms: medullary ischemia, formation of reactive oxygen species and direct tubular cell toxicity, especially in the patients with chronic kidney disease. The strategies of treatment, including stabilization of hemodynamic parameters and maintenance of normal fluid and electrolyte balance, were similar to the management of other types of acute kidney injury. Patient concerns: A 58-year-old woman experienced acute oligouria after complex percutaneous coronary ...

Cardiogenic shock (CS) is a physiologic state in which cardiac pump function is inadequate to perfuse the tissues. If CS is not rapidly recognized and treated, tissue hypoperfusion can quickly lead to organ dysfunction and patient death. Evaluation of patients with suspected CS should include an electrocardiogram, chest radiograph, laboratory studies, and bedside echocardiogram. Initial resuscitation is directed toward restoring cardiac output and tissue perfusion. Mechanical circulatory support is indicated for patients with CS who do not respond to pharmacologic therapy. Ultimately, these patients should undergo emergent...

Abstract Contrast-induced nephropathy (CIN) is an important complication following diagnostic radiographic imaging and interventional therapy. It results from administration of intravascular iodinated contrast media (CM) and is currently the third most common cause of hospital-acquired acute kidney injury. CIN is associated with increased morbidity, prolonged hospitalization and higher mortality. Although the importance of CIN is widely appreciated, and its occurrence can be mitigated by the use of pre- and post-hydration protocols and low osmolar instead of high osmolar iodine-containing CM, specific prophylactic...

Abstract BACKGROUND: Contrast-induced nephropathy (CIN) remains to be a potentially serious complication of radiographic procedures and is the third leading cause of the acute kidney injury (AKI) among hospitalized patients. This clinical trial was performed to assess the preventive effect of oral nicorandil on CIN in high-risk patients undergoing cardiac catheterization. METHODS: In this prospective, randomized, controlled trial, 128 patients with at least two risk factors for CIN undergoing elective percutaneous coronary intervention (PCI) were randomly assigned to either the nicorandil group or the control...

Authors: Sato A, Isoda K, Gatate Y, Akita K, Daida H Abstract A 69-year-old man was admitted to our hospital with cardiopulmonary arrest. Percutaneous cardio-pulmonary support (PCPS) using the right femoral artery and vein was initiated, because ventricular fibrillation continued. Although we succeeded in defibrillation after percutaneous coronary intervention (PCI), a chest radiograph indicated a pneumothorax in the right lung and a pulmonic contusion in the left lung caused by cardiopulmonary resuscitation. Two days after PCI, partial pressure of arterial oxygen (PaO2) from the right radial artery suddenly decrea...

Abstract Contrast-induced nephropathy (CIN) is one of the important complications of radiographic procedures, especially in patients with chronic kidney disease. It is also one of the common causes of acute kidney injury. The pathogenesis is postulated to be the effect of oxygen- free radicals and hyperosmolar stress on the renal medulla. It is reported that the production of superoxide is most active at acid environment. K/Na citrate is well known as a urine alkalini- zation medium, and this has been evaluated earlier with standard hydration for reduction of CIN and was stated to be efficient. We aimed to determi...

We present a case of refractory coronary artery vasospasm in the setting of eosinophilic granulomatosis with polyangiitis (EGPA). Typically, calcium channel blockers and nitrates are used to treat hyperreactive narrowing of the coronary vasculature but we propose this case was refractory to standard treatment due to the underlying pathology of EGPA. Alternative causes of coronary vasospasm when standard therapies fail should be considered.>
