Spontaneous coronary artery vasospasm is one of the important causes of acute chest pain syndromes. The diagnosis of diffuse multifocal spasm can be quite challenging and it could be easily mistaken for diffuse coronary artery disease. The use of intracoronary nitroglycerin can relieve spasm and reveal the real extent of coronary artery disease. Herein we present a case presenting with acute my...

Acute stent malapposition poses a significant risk for adverse cardiac events following percutaneous coronary intervention. Detection of acute traditionally relies on intracoronary imaging techniques, such as intravascular ultrasound and optical coherence tomography, which may be limited in developing countries due to accessibility issues. A new angiographic sign called the POT-PUFF has been in...

The Western Washington Intracoronary Streptokinase randomized trial1 first demonstrated that intracoronary thrombolytic therapy improved survival for patients presenting within 12 hours of symptom onset of acute myocardial infarction (MI). Perhaps equally important, this invasive study demonstrated that in-hospital and long-term survival was greatly improved in patients with patent infarctrelat...

BACKGROUND A honeycomb-like structure in the coronary artery is rarely diagnosed by intracoronary ultrasound or optical coherence tomography. Further, its structural mechanisms and response to interventional therapy remain unknown. CASE PRESENTATION A 59-year-old Japanese man was referred to our hospital because of acute decompensated heart failure with rapid atrial fibrillation. After receiv...

Objectives: The goal of this study was to evaluate the long-term safety and efficacy of intracoronary epinephrine in reversing refractory no-reflow during primary percutaneous coronary intervention (PCI). Methods: A total of 248 consecutive patients with acute myocardial infarction who had been treated from September 2009 to November 2010 at the Cardiology Department of Turkiye Yuksek Ihtisas H...
