The ageing population continues to suffer from its primary killer, cardiovascular disease (CVD). Despite recent advances in interventional medicinal and surgical therapies towards the end of the 20th century, the epidemic of cardiovascular disease has not been halted. Yet, rather than receding globally, the burden of CVD has risen to become a top cause of morbidity and mortality worldwide. Most CVD arises from thrombotic rupture of an atherosclerotic plaque, the pathologic thickening of coronary and carotid artery segments and subsequent distal ischemia in heart or brain...

Background: Good results of drug-eluting balloon (DEB) use are achieved in in-stent restenosis (ISR) lesions, small vessel disease, long lesions, and bifurcations. However, few reports exist about DEB use in acute myocardial infarction (AMI) with ISR. This study's aim was to evaluate the efficacy of DEB for AMI with ISR. Methods: Between November 2011 and December 2015, 117 consecutive patients experienced AMI including ST-segment elevation MI, and non-ST-segment elevation MI due to ISR, and received percutaneous coronary intervention (PCI)...

Vascular complications from transradial percutaneous coronary intervention (PCI) are rare. We report an unusual case of stridor after PCI due to brachiocephalic artery perforation, pseudoaneurysm formation, and development of a large mediastinal hematoma with tracheal compression. Endovascular repair of the brachiocephalic artery was achieved with covered stent placement at the neck of the pseudoaneurysm. This case highlights the importance of careful guide catheter placement from the right radial approach...

The optimal timing of percutaneous coronary intervention (PCI) in patients with non-ST-segment elevation myocardial infarction (NSTEMI), complicated by acute decompensated heart failure (ADHF), is unclear. A total of 1,027 patients with NSTEMI complicated by ADHF who underwent successful PCI were analyzed using a Korean multicenter registry. All patients were divided into 4 groups by the timing of PCI: group 1 (PCI < 2 hour after admission, n = 149), group 2 (2 to 24 hours, n = 577), group 3 (24 to 72 hours, n = 189), and group 4 (≥72 hours, n = 112)...

There has been great effort to improve clinical outcome in percutaneous treatment for coronary artery disease. Complementary to coronary angiography, intravascular ultrasound (IVUS) provides in vivo tomographic anatomic information, enabling to evaluate from the lumen to the vessel wall. As a result, IVUS has had a pivotal role to understand pathophysiology of coronary artery disease and improve clinical outcome. It provides preprocedural information to evaluate stenosis severity and plaque characteristics and helps with optimal stent deployment, minimizing underexpansion and geographic miss that are the major mechanisms of stent failure...

BACKGROUND: Lead aVR provides prognostic information in various settings in patients with ischemia. We aim to investigate the role of a positive T wave in lead aVR in non-ST segment myocardial infarction (NSTEMI). METHODS: In a prospective cohort study, we included 400 patients with NSTEMI. Presentation electrocardiogram (ECG) was investigated for presence of a positive T wave as well as ST segment elevation (STE) in aVR and study variables were compared. Predictors of primary outcome defined as hospital major adverse cardiovascular events (MACE) and secondary outcome, defined as three-vessel coronary disease and/or left main coronary artery stenosis (3VD/LMCA) stenosis in angiography, were determined in multivariate logistic regression analysis...

OBJECTIVES: The authors sought to evaluate the influence of coronary microcirculatory dysfunction (CMD) on the diagnostic performance of the quantitative flow ratio (QFR). BACKGROUND: Functional angiographic assessment of coronary stenoses based on fluid dynamics, such as QFR, constitutes an attractive alternative to fractional flow reserve (FFR). However, it is unknown whether CMD affects the reliability of angiography-based functional indices. METHODS: FFR and the index of microcirculatory resistance (IMR) were measured in 300 vessels (248 patients) as part of a multicenter international registry...

Antiplatelet agents with the active ingredients acetylsalicylic acid (Aspirin® protect 100), clopidogrel (Iscover®, Plavix®), prasugrel (Efient®) or ticagrelor (Brilique™) prevent the clumping of platelets and thus the formation of small clots at constrictions of the coronary arteries or on the metal struts of stents in the coronary artery or in bypass grafts. Large-scale studies have shown that taken regularly, these drugs can extend life and help prevent heart attacks. Especially in patients with newly implanted stents, the combination of the above-mentioned agents prevents sudden complete occlusion of the vessel concerned...

OBJECTIVES: To evaluate the outcomes of rotational atherectomy for heavily-calcified side branches of coronary bifurcation lesions. BACKGROUND: Side-branch (SB) preservation is clinically important but technically challenging in heavily-calcified non-left main true bifurcation lesions. SB rotational atherectomy (SB RA) is sometimes mandatory but the clinical outcomes are not well studied. METHODS: We retrospectively studied the outcomes of patients who underwent RA at our institute for heavily calcified, balloon-uncrossable or-undilatable SB lesions over an approximately 5-year period (January 2011 to September 2016)...

PURPOSE: Myocardial bridges (MB) have traditionally been considered a benign condition, but recent studies have demonstrated that the clinical complications can be dangerous. The transluminal attenuation gradient (TAG) obtained from coronary computed tomography angiography (CCTA) data (Retrospective ECG-triggered method) has been used in detecting significant stenosis in coronary artery caused by atherosclerosis. Contrast opacification difference (COD) was the parameters calculated as the change between attenuation of mural artery and the median attenuation of presumptive vessel segment; it was evaluated along with TAGstandardized (TAGs) and MB length for predicting MB with systolic compression (MB-SC) in patients diagnosed as MB in left anterior descending coronary artery (LAD) by CCTA or invasive coronary angiograph (ICA)...
