James Taylor Herbert, Miklos David Kertai
The increasing use of endovascular interventions coupled with the large number of published case series detailing complications attest to the likelihood that anesthesiologists will encounter a case of intravascular foreign body embolization during their careers. Transesophageal echocardiography is essential to the diagnosis and management of traumatic and intravascular foreign bodies embolized to the heart because it can identify not only the foreign body but also hemodynamically significant lesions to radiolucent anatomic structures prior to and during surgical exploration...

Left main coronary compression syndrome rarely occurs in patients with severe pulmonary hypertension. A 65-year-old woman with severe pulmonary hypertension due to an atrial septal defect suffered from angina on effort. Cardiac computed-tomography and coronary angiography revealed considerable stenosis of the left main coronary artery (LMA) caused by compression between the dilated main pulmonary artery trunk and the sinus of valsalva. Stenting of the LMA under intravascular ultrasound imaging was effective for the treatment of angina...

OBJECTIVES: To evaluate the outcomes of subadventitial stenting (SS) around occluded stents for recanalizing in-stent chronic total occlusions (IS-CTOs). BACKGROUND: There is little evidence on the outcomes of SS for IS-CTO. METHODS: We examined the outcomes of SS for IS-CTO PCI at 14 centers between July 2011 and June 2017, and compared them to historical controls recanalized using within-stent stenting (WSS). Target-vessel failure (TVF) on follow-up was the endpoint of this study, and was defined as a composite of cardiac death, target-vessel myocardial infarction, and target-vessel revascularization...

BACKGROUND: Proper vessel sizing during endovascular interventions is crucial to avoid adverse procedural and clinical outcomes. LumenRECON (LR) is a novel, nonimaging, 0.035-inch wire-based technology that uses the physics-based principle of Ohm's law to provide a simple, real-time luminal size while also providing a platform for therapy delivery. This study evaluated the accuracy, reliability, and safety of the LR system in patients presenting for a femoropopliteal artery intervention...

Acute myocardial infarction is a clinical cardiac emergency associated with potential and substantial morbidity and mortality. This disorder is triggered by an acute coronary syndrome caused by episodes of plaque ulceration, fissuration, or rupture with subsequent production of thrombogenic material and intravascular thrombus formation. The presence or absence of ST-segment elevation on the ECG defines the two main clinical spectrum of ST-segment elevation or non-ST-segment elevation myocardial infarction. In the last three decades, pharmacological and interventional management as well as in-hospital care have dramatically improved...

A 43-year-old man was admitted to our hospital with ST-segment elevation acute coronary syndrome. He had experienced myocardial infarction 19 months previously, and a bare-metal stent (BMS) had been implanted in the culprit distal right coronary artery at another hospital. Emergency coronary angiography showed thrombotic in-stent occlusion of the BMS. Intravascular ultrasound revealed an undersized stent compared with the size of the vessel and late stent malapposition (LSM) with abundant thrombi. The lesion was successfully recanalized via thrombectomy and plain old balloon angioplasty...

BACKGROUND AND OBJECTIVES: Interventional endoscopic ultrasound (EUS) is a promising novel approach for intravascular interventions. The aim of this study was to assess the feasibility and safety of a EUS-guided intrahepatic portosystemic shunt (EGIPS) with portal pressure gradient measurement in a live porcine model. METHODS: The left hepatic vein (LHV) or the inferior vena cava (IVC) was punctured with a needle that advanced into the portal vein (PV). A guidewire was then inserted into the PV, and a needle knife was used to create an intrahepatic fistula between LHV and PV...

BACKGROUND: The initial EROSION study (Effective Anti-Thrombotic Therapy Without Stenting: Intravascular Optical Coherence Tomography-Based Management in Plaque Erosion) demonstrated that patients with acute coronary syndrome caused by plaque erosion might be stabilized with aspirin and ticagrelor without stenting for ≤1 month. However, a long-term evaluation of outcomes is lacking. The aim of this study was to assess whether the initial benefit of noninterventional therapy for patients with acute coronary syndrome caused by plaque erosion is maintained for ≤1 year...

Procedural guidance with intravascular ultrasound (IVUS) imaging improves the clinical outcomes of patients undergoing percutaneous coronary intervention (PCI) by: 1) informing the necessity for lesion preparation; 2) directing appropriate stent sizing to maximize the final stent area and minimize geographic miss; 3) selecting the optimal stent length to cover residual disease adjacent to the lesion, thus minimizing geographic miss; 4) guiding optimal stent expansion; 5) identifying acute complications (edge dissection, stent malapposition, tissue protrusion); and 6) clarifying the mechanism of late stent failure (stent thrombosis, neointimal hyperplasia, stent underexpansion or fracture, or neoatherosclerosis)...

A 14-year-old boy presented with several months of increasing abdominal girth and fatigue. Imaging confirmed massive ascites and hepatic congestion secondary to central hepatic venous obstruction. Several large intrahepatic collateral veins were seen draining via caudate and emissary veins. After an unsuccessful attempt at retrograde recanalization utilizing intravascular ultrasound, the right hepatic vein was recanalized in an antegrade fashion by way of a prominent caudate collateral vein, and subsequently stented...

Percutaneous coronary intervention of chronic total occlusion is a particular interventional area which requires high level of operator's experience and the support of additional tools based on intracoronary image such as intravascular ultrasound in many cases to clarify difficulties during procedures and to increase success rate. Implantation of long stents in many cases, the presence of stump ambiguity, and the use of specific techniques in this kind of interventions, such as reverse controlled antegrade and retrograde subintimal tracking (CART) and reverse CART make necessary in many cases the use of intravascular ultrasound for a better understanding of the situation, for reducing eventual complications and increasing procedural success rate...

BACKGROUND: Even though longer stented lengths may increase the risk of restenosis, full coverage of diffuse long lesions with longer stents seems to be the optimal strategy for percutaneous coronary intervention (PCI) in the new drug-eluting stent (DES) era. However, it remains unclear whether this strategy will indicate favorable outcome or not. This study evaluated the impact of stent length on two-year clinical outcomes after PCI with the XIENCE Alpine everolimus-eluting stent. METHODS: This was a retrospective, non-randomized, observational study...

A 62-year-old Japanese man presented with chest pain indicating that acute myocardial infarction had occurred. Eleven years earlier, he underwent a splenectomy due to idiopathic portal hypertension. Coronary angiography revealed diffuse stenosis, with calcification in the left anterior descending coronary artery (LAD). We performed a primary percutaneous coronary intervention (PCI). We deployed two drug-eluting stents with sufficient minimal cross-sectional stent area by intravascular ultrasound and thrombolysis in myocardial infarction (TIMI) 3 flow...

Small and broad-necked aneurysms are generally very difficult to treat using endovascular therapy. The arrival of the low-profile stent (e.g., Low-profile Visualized Intraluminal Support; LVIS) has enabled reconstructive treatment for these aneurysms. In addition, the bulging technique using LVIS is an effective and attractive technique for performing stent-assisted coiling to preserve parent arteries and achieve neck coverage. We report here a patient with a small and wide-necked ruptured basilar artery (BA) top aneurysm, in whom successful treatment was achieved by stent-assisted coiling with LVIS Jr...

Development of new atherosclerotic lesions within the neointima of stented vessels has been recognized as a novel disease manifestation of atherosclerosis (neoatherosclerosis), often manifesting as in-stent restenosis (ISR) or in-stent thrombosis (ST). The pathobiology of this entity is still not fully understood and definite diagnosis is challenging owing to limitations in resolution of contemporary intravascular imaging modalities and lack of consequent histopathology correlation studies. Yet, intravascular imaging has emerged as the gold standard for the diagnosis of in-stent pathologies, the most routinely used modalities being intravascular ultrasound (IVUS) and optical coherence tomography (OCT)...

OBJECTIVES: The authors sought to explore the comparative clinical efficacy of different imaging modalities for guiding percutaneous coronary interventions (PCI). BACKGROUND: Coronary angiography (CA) is the standard imaging modality for intraprocedural guidance of PCI. Intracoronary imaging techniques, including intravascular ultrasound (IVUS) and optical coherence tomography (OCT), can overcome some limitations of CA. METHODS: Comprehensive hierarchical Bayesian network meta-analysis of randomized clinical trials and adjusted observational studies comparing clinical outcomes of PCI with stent implantation guided by CA, IVUS, or OCT...
