Intracoronary imaging

Masafumi Nakayama, Masaharu Hirano, Sonoka Goto, Akifumi Watanabe, Takashi Uchiyama
A 40-year-old man was admitted to our hospital for chest pain after smoking. Coronary computed tomography angiography showed severe stenosis in the left anterior descending artery. The stenosis site had no plaque on stretched curved multiplanar reconstruction and short-axis images. Coronary angiography revealed improvement of the severe stenosis after the intracoronary administration of isosorbide dinitrate in the left anterior descending artery. Intravascular ultrasound demonstrated negative remodeling without a plaque and diffuse intima with media thickening at the stenosis site...

PURPOSE OF REVIEW: Spontaneous coronary artery dissection (SCAD) is a non-iatrogenic and non-traumatic separation of the coronary arterial wall. While SCAD represents an important cause of myocardial infarction, optimal diagnostic and therapeutic options remain challenging. We sought to review recent studies and provide an update on diagnosis and management of SCAD. RECENT FINDINGS: Coronary angiography is the first-line diagnostic modality for SCAD, with three angiographic features commonly observed in SCAD: type 1 (pathognomonic angiographic appearance with contrast staining of the arterial wall), type 2 (long coronary stenosis), and type 3 (focal tubular stenosis)...

Aims: Coronary high-intensity plaques (HIPs) with a high plaque-to-myocardial signal intensity ratio (PMR) on non-contrast T1-weighted imaging in patients with stable coronary artery disease (CAD) are associated with future coronary events. To characterize the morphological substrate of HIP, we performed a correlative optical coherence tomography (OCT) study. Methods and results: We examined 137 lesions in 105 patients with stable angina pectoris or silent myocardial ischaemia scheduled for percutaneous coronary intervention (PCI) using a 3 T magnetic resonance scanner...

OBJECTIVE: Coronary vasodilator function and atherosclerotic plaque progression have both been shown to be associated with adverse cardiovascular events. However, the relationship between these factors and the lipid burden of coronary plaque remains unknown. These experiments focus on investigating the relationship between impaired coronary vasodilator function (endothelium dependent (salbutamol) and endothelium independent (glyceryl trinitrate)) and the natural history of atheroma plaque progression and lipid burden using dual modality intravascular ultrasound (IVUS) and near-infrared spectroscopy (NIRS) imaging...

OBJECTIVES: This study investigated the clinical and angiographic long-term outcomes of intracoronary transfusion of circulation-derived CD34+ cells for patients with end-stage diffuse coronary artery disease unsuitable for coronary intervention. DESIGN AND SETTING: A single-center prospective randomized double-blinded phase I clinical trial. Thirty-eight patients undergoing CD34+ cell therapy were allocated into groups 1 (1.0 × 10 cells/each vessel; n = 18) and 2 (3...

We aimed to compare the safety and efficacy of rotational atherectomy (RA) and orbital atherectomy (OA) during percutaneous coronary intervention in an all-comer population with severely calcified lesions. We included all patients who underwent percutaneous coronary intervention with OA or RA in our institution from October 2013 until October 2016. Comparison of baseline and procedural characteristics, along with acute complication rates and postprocedural cardiac enzyme elevation, was performed. There were 191 RA and 57 OA patients...

We report a case of percutaneous coronary intervention for spontaneous multi-vessel coronary dissection including the left main coronary artery. This case suggests that intracoronary imaging is useful for understanding the complex anatomy and for choosing the appropriate management for effective revascularization. Furthermore, cutting balloon angioplasty prior to stenting is useful for preventing the longitudinal extension of the intramural hematoma and avoiding unnecessary stent implantation.

BACKGROUND: Fractional flow reserve (FFR) is widely used for the assessment of myocardial ischemia. Intravascular ultrasound (IVUS) is an intracoronary imaging method that provides information about lumen and vessel morphology. Previous studies on the expanded use of IVUS to identify functional ischemia have noted an association between anatomy and physiology, but IVUS-derived minimum lumen area (MLA) has a weak-moderate correlation with myocardial ischemia compared with FFR. We developed a method to calculate FFR using IVUS-derived anatomical information for the assessment of myocardial ischemia...

Background: Intracoronary imaging is an important tool for guiding decision making in the cardiac catheterization laboratory. Sources of data: We have reviewed the latest available evidence in the field to highlight the various potential benefits of intravascular imaging. Areas of agreement: Coronary angiography has been considered the gold standard test to appropriately diagnose and manage patients with coronary artery disease, but it has the inherent limitation of being a 2-dimensional x-ray lumenogram of a complex 3-dimensional vascular structure...

Aims: To compare endothelium-dependent vasomotor function and vascular healing 15 months after implantation of two new-generation drug-eluting stents and biovascular scaffolds (BVS). Methods and results: A total of 28 patients previously treated with a SYNERGY stent (bioabsorbable polymer everolimus-eluting stents (BP-EES)), a PROMUS stent (persistent polymer everolimus-eluting stents (PP-EES)) or an ABSORB (BVS) underwent control coronary angiography, 15 months after implantation, coupled with optical coherence tomography imaging and supine bicycle exercise...

Coronary heart disease (CHD) continues to be understudied, underdiagnosed, and undertreated in women. Gender and age bias complicate the evaluation of women with acute coronary syndrome (ACS). As a result, conditions like spontaneous coronary artery dissection (SCAD) are often missed. SCAD is an infrequent yet important cause of myocardial infarction (MI) with a predilection for young to middle aged women. The condition is thought to be under-reported, likely a result of both low index of suspicion as well as an unfamiliarity with SCAD's angiographic variants...

BACKGROUND AND AIMS: Whether coronary calcification is correlated with plaque/media shrinkage (PS) remains unclear. The aim of this study was to assess the relationship between the calcification process and PS, combining serial optical coherence tomography (OCT) and intravascular ultrasound (IVUS) in vessels treated with bioresorbable vascular scaffolds (BVS). METHODS: In 15 patients (16 vessels), OCT and IVUS images were matched using anatomic landmarks at post-procedure and five years...

Background: Suboptimal myocardial reperfusion is common in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). Furthermore, it results in increased infarct size and mortality rates. We performed a meta-analysis to evaluate the role of aspiration thrombectomy (AT) combined with intracoronary administration of glycoprotein IIb/IIIa inhibitors (GPI) in the improvement of myocardial reperfusion and clinical outcomes...

A 46-year-old man underwent coronary angiography for stable angina. He developed inferior ST-segment myocardial infarction during the angiography. Intravascular ultrasound (IVUS) findings suggested coronary vasospasm. Intracoronary administration of isosorbide dinitrate restored the coronary flow. This case illustrates the essential role IVUS imaging played in establishing the diagnosis of catheter-induced coronary vasospasm.

BACKGROUND: Coronary atherosclerosis progresses faster in patients with diabetes mellitus (DM) and causes higher morbidity and mortality in such patients compared to non-diabetics ones (non-DM). We quantify changes in plaque volume and plaque phenotype during lipid-lowering therapy in DM versus non-DM patients using advanced intracoronary imaging. METHODS: We analyzed data from 61 patients with stable angina pectoris included to the PREDICT trial searching for prediction of plaque changes during intensive lipid-lowering therapy (40 mg rosuvastatin daily)...

In-stent chronic total occlusion (CTO) represents a challenging lesion subset for percutaneous coronary intervention (PCI), and although a true-to-true lumen crossing is the first-line strategy, a subadventitial approach may become necessary. Here we describe a case of successful in-stent right coronary artery CTO-PCI performed with subadventitial crossing, crushing of the occluded stents, and advancement of a mother-and-child catheter to the distal right coronary artery through the subadventitial space to allow stent delivery...
