Feasibility and safety of robotic PCI in China: first in man experience in Asia.

Objectives: To evaluate the feasibility and safety of a second generation robotic percutaneous coronary intervention (R-PCI) system in China.

Background: Robotic PCI has been shown to be an effective method for conducting coronary interventions. It has further benefits of more accurate lesion measurement, improved stent deployment, reduced incidence of geographic miss and reduction of operator radiation exposure.

Analysis of anomalous origin of coronary arteries by coronary angiography in Chinese patients with coronary artery disease.

With the development of coronary angiography for the diagnosis of coronary artery disease, its clinical significance in detecting coronary artery anomalies and evaluating the seriousness is attracting more attention. In the study we aimed to assess the prevalence of anomalous origin of coronary arteries in a Chinese population who underwent coronary angiography for coronary artery disease, and explore any patterns in the common variants and typical anomalies, especially the potentially serious ones. Patients who underwent coronary angiography from January 2013 to December 2016 in Fuwai Hospital were included.

Improvement of Image Quality and Diagnostic Performance by an Innovative Motion-Correction Algorithm for Prospectively ECG Triggered Coronary CT Angiography.

Objective: To investigate the effect of a novel motion-correction algorithm (Snap-short Freeze, SSF) on image quality and diagnostic accuracy in patients undergoing prospectively ECG-triggered CCTA without administering rate-lowering medications.

Materials And Methods: Forty-six consecutive patients suspected of CAD prospectively underwent CCTA using prospective ECG-triggering without rate control and invasive coronary angiography (ICA). Image quality, interpretability, and diagnostic performance of SSF were compared with conventional multisegment reconstruction without SSF, using ICA as the reference standard.

Coronary In-Stent Restenosis: Assessment with Corrected Coronary Opacification Difference across Coronary Stents Measured with CT Angiography.

Purpose: To determine whether changes in coronary opacification normalized to the aorta (corrected coronary opacification [CCO]) across stents can help identify in-stent restenosis (ISR) severity with use of invasive coronary angiography as the standard of reference.

Materials And Methods: This study was approved by the institutional review board, and the requirement to obtain informed consent was waived. The authors retrospectively analyzed 106 patients (88 men, 18 women; mean age, 59.

[Clinical outcome of patients undergoing emergent coronary artery bypass grafting following failed percutaneous coronary intervention in stent era].

Objective: To explore clinical outcomes of patients undergoing emergent coronary artery bypass grafting (CABG) following failed percutaneous coronary intervention (PCI) in the stent era.

Methods: Eleven patients who underwent emergent CABG following failed PCI from January, 2002 to December 2010 were enrolled. The in-hospital follow-up included cardiac deaths, Q-wave myocardial infarction, kidney failure, and cerebrovascular events.

[The in-hospital outcome and predictors of major adverse cardiac events after transradial intervention in patients with coronary artery disease].

Objective: The purpose of this study is to evaluate the in-hospital clinical outcome of patients with coronary artery disease who underwent transradial intervention (TRI) and analyze the predictors of clinical outcome.

Methods: From May 2004 to May 2009, there were 16 281 patients who underwent transradial intervention, as well as 5388 patients who underwent transfemoral intervention (TFI) at our institution. The clinical characteristics, procedural characteristics, and in-hospital clinical adverse events were compared between TRI and TFI groups.

[Comparison of outcomes after transradial intervention in patients of different age groups].

Objective: To compare the in-hospital clinical outcome of patients with coronary artery disease in different age groups [< 65 years (younger), 60 to 79 years (older), and ≥ 80 years (octogenarians)] underwent transradial intervention (TRI) so asto analyze the predictors of adverse events.

Method: From May 2004 to May 2009, a total of 16 293 patients underwent transradial intervention at our institution. The in-hospital outcome for patients in different age groups after TRI was investigated.

Profound thrombocytopenia induced by clopidogrel with a prior history of long-term safe administration.

Clopidogrel has shown an excellent safety, tolerability and efficacy ever since its marketing. However, here we report a rare case with profound thrombocytopenia following clopidogrel administration previously safely exposed to this same drug. This reminds us that thrombocytopenia might be induced by clopidogrel even with a prior, safe history of long-term administration.

Coronary intervention in patients>or=75 years old with ST-elevation myocardial infarction: in-hospital and 6-month clinical outcomes.

Background: ST-segment elevation myocardial infarction (STEMI) in elderly patients presents specific clinical characteristics. The study on percutaneous coronary intervention (PCI) in elderly patients (>or=75 years) with STEMI, however, has less been performed.

Methods: In the present study, 522 consecutive STEMI patients undergoing PCI within 12 hours from symptom onset were investigated, and clinical characteristics and in-hospital and 6-month outcomes of 66 elderly patients (>or=75 years, group A) were compared to those of 456 younger patients (<75 years, group B).

[Clinical and angiographic outcome in coronary artery disease patients with type-II diabetes mellitus undergoing elective bare-metal stenting or drug-eluting stenting].

Objective: To compare the clinical and angiographic outcome in patients with type-II diabetes mellitus undergoing drug-eluting stent (DES) or bare-metal stent (BMS).

Methods: A total of 139 consecutive diabetic patients (114 males) with coronary disease who underwent successful elective percutaneous coronary intervention with DES (n = 83 with 151 lesions) or BMS (n = 56 with 70 lesions) on native coronary arteries from April 2004 to August 2005 at our institution were included in this study. All patients were treated according to guidelines and coronary angiography was repeated at 6 months post procedure in all patients.

Coronary restenotic reduction of drug-eluting stenting may be due to its anti-inflammatory effects.

The development of coronary stent has revolutionized the field of interventional cardiology by reducing the incidence of restenosis after balloon angioplasty. However, the stent has still associated with a serious complication, namely, in-stent restenosis. Although, restenosis following coronary stenting has long been attributed to neointimal proliferation, thrombosis, and negative remodeling, the inflammation may be a trigger for those vascular reactions following coronary stenting.

[Clinical and angiographic outcome in patients undergoing elective bare- metal stenting or drug-eluting stenting for total occlusion lesion].

Objective: To compare the clinical and angiographic outcome in patients with total occlusion lesion treated with drug-eluting stent (DES) or bare-metal stent (BMS).

Methods: A total of 155 (138 males) consecutive patients with total occlusion lesion underwent successful revascularization with DES (n = 74) or BMS (n = 81) in our hospital were included in this study. All patients received aspirin 300 mg and clopidogrel 75 mg once daily for at least 3 months after the procedure.

[Compare drug-eluting stent to bare-metal stent in prognosis on treating diffuse coronary lesions].

Objective: Compare drug-eluting stent (DES) to bare-metal stent (BMS) in prognosis on treating diffuse coronary lesions and analysis risk factor of treating complex and diffuse lesions in PCI.

Methods: 205 consecutive patients with complex and diffuse coronary lesions enrolled our hospital, who were treated with more than 25 mm long DES or BMS. We exclude unsuccessful operation and location.
