We herein describe a case of acute myocardial infarction due to spontaneous coronary artery dissection complicated by vasospastic angina. Given the need for different clinical management strategies of these cardiac manifestations, clinicians should consider the possibility of concomitant vasospasm in cases of spontaneous coronary artery dissection.

Background: Failed aortofemoral and femoropopliteal bypass grafts in the lower extremity artery usually result in acute limb ischemia. Endovascular treatment and surgical revascularization have been reported for limb salvage.

Case Presentation: A 72-year-old Japanese man was admitted with acute limb ischemia due to failed aortofemoral and femoropopliteal bypass grafts.

Spontaneous coronary artery dissection (SCAD) is a rare condition that may have a serious outcome because of acute coronary syndrome. The condition especially affects young women. We evaluated a middle-aged male patient with a non-ST segment elevation myocardial infarction caused by multivessel SCAD.

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.

Whether the lesion morphology and associated interventional procedures for the left main coronary artery disease (LMCA) could affect clinical outcome is still controversial. Therefore, we examined the impact of lesion morphology and associated procedures on clinical and angiographic outcomes of stenting for the LMCA. Among 7,660 patients with coronary intervention registered, we analyzed early angiographic results of 228 patients (179 men, mean age 69.

A 67-year-old man who had a history of syncope was admitted because of effort angina. The sinus node (SN) was the single blood supply from the right coronary artery (RCA). After we implanted 2 everolimus-eluting stents for RCA, slow-flow occurred and the SN artery was occluded, and junctional escape rhythm was sustained.

A 68-year-old man with acute ST elevation myocardial infarction (STEMI) underwent emergent coronary angiography which showed total occlusion in the proximal right coronary artery (RCA). Gray-scale intravascular ultrasound (IVUS) revealed the culprit lesion was expansively remodeled and contained ruptured and echolucent plaques with spotty calcification, whereas thin-capped fibroatheroma and a large amount of scattered necrotic core were observed by virtual histology (VH)-IVUS. After stent implantation in the proximal RCA under a filter protection, filter-no-reflow phenomenon occurred and thrombus-like defect was observed in the mid RCA.

A young adult patient with untreated sarcoidosis spontaneously developed a left ventricular (LV) aneurysm in the anterolateral free wall. Single-photon emission computed tomography (SPECT) using Gallium-67 clearly demonstrated widespread abnormal uptake, including the LV aneurysm. Thallium-201 SPECT revealed a perfusion defect in the anterolateral wall, and abnormal uptake of technetium-99m pyrophosphate was seen, especially in the borders of the defect lesion.
