A stent in a false lumen is a common cause of stent occlusion after coronary percutaneous coronary artery intervention therapy, particularly in the culprit lesion of acute myocardial infarction. Here, we present an unusual case of successful recanalization of the proximal right coronary artery with implementation of another stent to crush the previous stent in the false lumen.
Stent expansion and in-stent thrombus sign in the Trevo stent retriever predict recanalization and possible etiology during mechanical thrombectomy: A case series of 50 patients with acute middle cerebral artery occlusion.
The interaction between the stent retriever and clot is a key factor for recanalization during mechanical thrombectomy.
Anomalous origin of left coronary artery (LCA) from the right coronary cusp with an intramural course is usually managed with unroofing of the intramural segment. Available literature demonstrates an uneventful course following surgery in most patients. Coronary stenosis following the unroofing procedure treated with percutaneous coronary intervention has not been described in the past. We describe a case where an 11-year-old girl with anomalous origin of the LCA from the right coronary cusp presented with ...
The purpose of this study was to compare the stent deformation, obstruction of stent struts at a jailed side branch (SB) ostium, and stent strut malapposition after a repetitive proximal optimizing technique (re-POT) sequence between bifurcation lesions with and without stent links at SB ostia in ex vivo experimental setting.
Even in the drug-eluting stent era, ostial lesion of the right coronary artery (RCA) still remains therapeutic challenge for interventional cardiologists. Case Series Case 1 (76 y.o. male) with angina on effort underwent transradial stent-less percutaneous coronary intervention (PCI) using rotational atherectomy (RA) followed by drug-coated balloon (DCB) dilation alone (RA/DCB) against a calcified de novo RCA ostial lesion. Case 2 (86 y.o. female) with recurrent unstable angina and hemodialysis underwen...
Coronary artery perforation (CAP) during percutaneous coronary intervention is a rare but serious complication. Treatment options of CAP include prolonged balloon inflation, covered stent, and coil embolization. Although most cases of CAP can be treated with prolonged balloon inflation, some cases, especially Ellis grade III CAP require covered stents or coiling. Covered stents may require a large bore guide catheter and have a high rate of restenosis, which can be a limiting factor in patients with severe ...
Several publications from our group and others have shown that a main cause of middle fiber block or left septal fascicular block of the left bundle of His is proximal obstruction of the left anterior descending coronary artery, before its first septal perforator branch, since this fascicle is the only one of the three fascicles irrigated exclusively by this artery. We present a case in which the phenomenon occurred transiently, causing prominent anterior QRS forces, confirmed by coronary angiography.
The bovine arch is the most common variant of the aortic arch and occurs when the innominate artery shares a common origin with the left common carotid artery. We report an endovascular repair of aortic arch aneurysm in patients with a bovine arch using the Najuta proximal scalloped and fenestrated stent graft.
A wider angle between the left anterior descending coronary artery (LAD) and left circumflex coronary artery (LCX) has been suggested to induce plaque formation in the arterial system via changes in shear stress. However, the relationship between the left main coronary artery (LM)-LAD angle and LAD stenosis has not been investigated. Therefore, we aimed to evaluate the associations between the LM-LAD and LAD-LCX angles and LAD stenosis.
Bilateral congenital coronary artery fistulae complicated with a giant coronary artery aneurysm is a very rare condition. A coronary artery aneurysm is a coronary artery dilatation that exceeds the diameter of normal adjacent segments or the diameter of the patient's largest coronary vessel by 1.5 times. The complications associated with a coronary artery aneurysm include thrombosis, embolization, rupture, vasospasm, congestive heart failure and infectious endocarditis. We report on a 63-year-old woman pres...
Infected coronary artery aneurysms (ICAA) represent a rare but potentially fatal complication of pre-existent atherosclerotic or non-atherosclerotic coronary artery disease, percutaneous coronary artery intervention, endocarditis or extracardiac infection.
Injury to the coronary circulation during percutaneous interventions is an existent risk. One of these is coronary artery perforation that can have grave consequences. Fortunately, this is rare and overall there is a declining incidence of complications due to technological advances and extensive experience over time. Predictors of coronary artery perforation include the administration of glycoprotein IIb/IIIa inhibitors, the use of hydrophilic guide wires, and the use of noncompliant high-pressure intracor...
The contemporary limb outcomes and costs of stent-based vs non-stent based strategies in endovascular revascularization of femoropopliteal (FP) peripheral artery disease (PAD) are not well understood.
Given the uncertainty regarding the degree and prevalence of spontaneous healing following spontaneous coronary artery dissection (SCAD), the aim of this study was to assess the angiographic characteristics of the dissected segments in a large cohort of patients with SCAD who underwent subsequent repeat coronary angiography.
Coronary endarterectomy (CE) in coronary artery bypass grafting (CABG) is occasionally required to achieve revascularization in diffusely diseased vessels. Its beneficial effect has been questioned because of an increased risk of perioperative mortality and morbidity; however, its influence on the long-term outcome remains uncertain. The purpose of the study was to evaluate the impact of adjunct CE on the incidence of a first postoperative angiogram and the need for repeat intervention and on late deaths af...
Comparative outcomes of coronary-artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) for left main coronary artery (LMCA) disease were previously reported. However, data on very long-term (>10 years) outcomes are limited.
To date there is scarce published evidence reporting the dual blood supply reaching anterior papillary muscle (APM), which descends from both major coronary arteries. Such a vascular configuration can prevent the dysfunction of right ventricular entire valvular system in case of the occlusion of proximal part of either right coronary artery (RCA) or left coronary artery (LCA). The aim of our study was to determine the vascular pattern of APM blood supply which originates from two main coronary arteries, in ...
Embolic myocardial infarction account for ≈3% of all ST-segment myocardial infarction and represents a challenge often left no-reperfused because current thrombectomy technologies are inefficient to grab thrombus wedged into distal coronary arteries. We present the case of a 34-year-old man who presented with anterior STEMI and a proximal left anterior descending coronary artery ulcerated plaque with a great thrombus burden, which led to distal embolization. Failure of several attempts of manual and rheol...
: A 54-year-old woman with a history of stage IV nonsmall-cell lung cancer, on treatment with chemiotherapy was hospitalized for acute coronary syndrome. Coronary angiography showed a tight stenosis of ostial left main coronary artery (LMCA) probably caused by external compression. Computed tomography scan confirmed LMCA compression and entrapment between a neoplastic mass and the root of the aorta, with vessel collapsing during diastole but patency and narrowing in systole. A drug-eluting stent was then su...
Dobutamine stress echocardiogram (DSE) is considered a safe and reliable method for screening for underlying myocardial ischaemia. We report a case of a 60-year-old man who developed inferior ST-segment elevation myocardial infarction within 30 minutes of a normal DSE. The patient was found to have a 99% in-stent restenosis in the mid-right coronary artery with significant thrombosis for which successful percutaneous coronary intervention (PCI) was performed. Acute coronary syndrome after a normal DSE has...
To evaluate the incidence of in-stent restenosis (ISR) at 12-month follow-up, in patients treated with new dual-layer Roadsaver (Terumo Corp, Tokyo, Japan) carotid artery stent (CAS).
Coronary calcification is a hard challenge for the interventional cardiologist, as it is associated with incomplete stent expansion and frequently stent failure. In recent years, innovative techniques, such as rotational atherectomy, have been developed to treat coronary calcification. However, these are burdened with an increased procedural risk. We report the case of a 60-year-old Caucasian man treated 1 month before at another center with primary coronary angioplasty and stenting of the ramus intermedius...
This is a case report of a 29-year-old, male applicant for life insurance who was discovered to have an absence of the left main coronary artery (LMCA), with the left anterior descending coronary artery (LAD) and left circumflex coronary artery (LCX) each arising directly from the left sinus of Valsalva. A brief review of several types of coronary artery anatomic variants will be presented.
