We report a case of a patient in whom collateral flow originating from the left anterior descending coronary artery was initially associated with a right coronary artery stenosis; seven months after successful angioplasty of the right coronary artery lesion, a severe left anterior descending stenosis developed and induced reversed collateral flow from the right coronary artery through the same ...
OBJECTIVES The aim of this study was to perform an investigation of the effects of the longitudinal straightening of coronary arteries by stents and the possible association with major adverse cardiac events (MACE) (primary end point) and angiographic restenosis (secondary end point). BACKGROUND Stent deployment straightens a tortuous artery, and any consequent arterial longitudinal stretch m...
Here, we present a case of 56-year-old man with acute myocardial infarction. The patient underwent percutaneous coronary intervention (PCI) at the left main bifurcation and mid-left anterior descending artery using drugeluting stents. Four months after PCI, was readmitted for cardiac arrest. Coronary angiography (CAG) revealed stent thrombosis in main-toproximal in-stent restenosis circumflex a...
BACKGROUND The results of stent implantation for small coronary disease have been inconclusive. The purpose of the present study was to evaluate the factors in predicting the risk of angiographic restenosis after 2.5-mm stent implantation for small coronary arteries. METHODS AND RESULTS The study group comprised 134 consecutive patients who had a reference small coronary artery with diameter ...
BACKGROUND Lipid-rich plaque (LRP) is thought to be a precursor to cardiac events. However, its clinical significance in coronary arteries has never been systematically investigated. OBJECTIVES This study investigated the prevalence and clinical significance of LRP in the nonculprit region of the target vessel in patients undergoing percutaneous coronary intervention (PCI). METHODS The stud...
Drug-eluting balloon (DEB) with angioplasty a paclitaxel-coated balloon catheter is an effective treatment option in patients with in-stent restenosis (ISR) after a drug-eluting stent (DES). We describe a case in which 'no-reflow' phenomenon developed after DEB angioplasty of a DES ISR lesion. Coronary flow was restored after intracoronary administration of nicorandil.
BACKGROUND Intracoronary ultrasound (IVUS) has been used as an adjunctive method in order to optimize implantation of stents. However, the impact of this method in some outcomes is controversial. OBJECTIVE To systematically review the impact of routine IVUS-guided coronary stent as compared to angiographic-guided, on clinical and angiographic outcomes. METHODS A search of databases (MEDLINE...
OBJECTIVES This study was performed to evaluate hemodynamic alterations of stent implantation after Doppler flow-guided balloon angioplasty (BA). BACKGROUND There is controversy regarding the effect of stent implantation on coronary hemodynamics after suboptimal and optimal BA. METHODS A total of 523 of 620 patients underwent Doppler-guided BA in the setting of a multicenter study and were ...
Homogeneity of microvascular resistance in different perfusion areas of the same heart is generally assumed. We investigated the effect of the severity of an epicardial stenosis on microvascular resistance in 27 patients with coronary artery disease and stable angina. All patients had an angiographically normal coronary artery, an artery with an intermediate lesion, and an artery with a severe ...
