Successful management of a giant unruptured mycotic coronary artery aneurysm after coronary angioplasty

Coronary artery stent infection has been reported with both bare metal stent and drug eluting stent and can present as mycotic coronary artery aneurysm, pseudoaneurysm, myocardial abscess, pericarditis or exudative effusion. Infection at the site of coronary stent implantation is rare and is believed to result typically from either direct stent contamination at the time of delivery or transient bacteraemia from access site. Introduction of drug-eluting stent (DES) has led to a marked reduction in the problem of in-stent restenosis across all patient subsets and lesions complexities. Recently, several case reports of pseudoaneurysm formation after DES implantation have been reported in the literature. We describe the successful surgical management of giant mycotic pseudoaneurysm of left anterior descending artery (LAD) presenting as fever of unknown origin. This report illustrates the importance of early detection and prompt management of these rare coronary pseudoaneurysms, which is a highly lethal condition.

Mycotic Pseudoaneurysms of the Coronary Arteries

Mycotic coronary artery aneurysms are rare and are often fatal without early recognition and prompt surgical management. We present a case of mycotic pseudoaneurysm of the left main coronary artery (LMCA) after disseminated methicillin-sensitive Staphylococcus aureus (MSSA) bacteraemia. A review of the literature in regards to the surgical management of coronary artery mycotic pseudoaneurysms was conducted. There were 26 reported cases of surgical management of coronary artery mycotic pseudoaneurysms. Coronary artery bypass surgery (CABG) and excision was the most common management (73.1% of cases reviewed). This case highlights the difficultly in diagnosing mycotic coronary artery pseudoaneurysms.

Giant Coronary Artery Pseudoaneurysm after Drug-Eluting Stent Implantation

Formation of coronary artery pseudoaneurysm after percutaneous coronary intervention is rarely reported. A close review of available literature indicates a trend of growing incidence in recent times. Here, we present a case of coronary pseudoaneurysm developing in the left circumflex artery within 50 days of sirolimus-eluting stent implantation in a 47-year-old man who was treated for triple-vessel coronary artery disease. Initially, the patient refused any further treatment. However, considering the rapid growth of pseudoaneurysm and increased severity of symptoms at subsequent follow-up, we decided to treat giant pseudoaneurysm with embolization coils. The procedure was successful and the patient remained asymptomatic thereafter.

Second Redo for Composite Graft Pseudoaneurysm with Transcutaneous Rupture.

Six months after a composite graft redo operation repairing two pseudoaneurysms at the distal suture line and the right coronary artery, respectively, a patient returned asymptomatic and in good general condition but with new presternal bulges. Computed tomography and angiography diagnosed a new pseudoaneurysm of the left coronary artery, and on frank rupture, acute re-repair was undertaken with the aid of presternotomy hypothermic circulatory arrest. Temporary postoperative neurological dysfunction subsided and recovery was otherwise uneventful.

Enlarged coronary artery pseudoaneurysm after drug-eluting stent implantation

A 73-year-old man with 2-vessel coronary artery disease underwent a staged percutaneous coronary intervention that resulted in rupture of the right coronary artery and pseudoaneurysm formation. Although the pseudoaneurysm regressed over a week, it reexpanded after a year. Resection of the pseudoaneurysm and coronary artery bypass grafting were performed. The drug-eluting stent at the coronary artery injury site may have delayed healing and remodeling of the artery, thus contributing to reexpansion of the pseudoaneurysm.

Non-invasive follow-up of a coronary artery pseudoaneurysm after percutaneous transluminal coronary rotational atherectomy (PTCRA)

ABSTRACT Percutaneous transluminal coronary rotational atherectomy (PTCRA) is an established treatment for very calcifi ed and/or undilatable coronary lesions. In contrast to data from directional coronary atherectomy (DCA) procedures, coronary artery aneurysms (CAA) or pseudoaneurysms have not routinely been described as a complication after PTCRA. We present a case of a 74-year-old patient, with a major CAA, found on a routine control coronary angiogram 4 months after a PTCRA of LAD complicated by a coronary perforation. A conservative management guided by coronary CT angiography is proposed.

Successful treatment of coronary artery pseudoaneurysm by graft stent, which developed after the implantation of bare metal stent

Koroner arter psodoanevrizmasi, perkutan koroner giri­sim sonrasi nadir gorulmesine karsin olumcul olabilen bir komplikasyondur. Tanisi konuldugunda perkutan ya da cerrahi olarak tedavi edilmesi gerekir. Uygun vakalarda greft kapli stent tercih edilen tedavi yontemidir. Bu yazida sol on inen koroner artere ciplak metal stent implantasyo­nu sonrasi gelisen koroner arter psodoanenvrizmasinin greft stent ile basarili tedavisinin yapildigi bir olgu sunul­du.

Coronary Artery Pseudoaneurysm: Closure With Pericardium-Covered Stents, Guided by Cardiac Computed Tomography Angiography

Coronary aneurysms are found in approximately 5% of patients undergoing coronary angiography. We describe a case of a coronary artery pseudoaneurysm. The use of cardiac computed tomography angiography is demonstrated in the planning and follow-up of a percutaneous closure of the pseudoaneurysm with pericardium-covered stents.

Iatrogenic Giant Coronary Artery Pseudoaneurysm With “Daughter Aneurysm” Formation

Coronary pseudoaneurysms rarely occur spontaneously; rather, they are more commonly seen as a complication of coronary intervention. We present a case of a giant right coronary artery pseudoaneurysm with partial thrombosis after arterial perforation during percutaneous intervention for acute myocardial infarction and formation of a "daughter aneurysm" due to a contained rupture 12 years later. Right coronary pseudoaneurysm repair and coronary artery bypass grafting were eventually performed 16 years after the acute event. Cardiac magnetic resonance imaging, coronary computed tomography angiography, and autopsy findings are shown.

Coronary Artery Pseudoaneurysm Following Blunt Trauma

A 42-year-old male was admitted with persistent atypical chest pain following a motorcycle accident six months previously. A pseudoaneurysm, diagnosed by transthoracic echocardiography and computed tomography, was excised and the right coronary artery underwent bypass grafting.

Coil embolization of left coronary artery pseudoaneurysms arising as a complication of percutaneous coronary intervention

Coronary aneurysms and pseudoaneurysms have been described as rare complications following percutaneous coronary intervention (PCI). There is limited data available on the optimal treatment strategy for these conditions. Use of noninvasive techniques including covered stents has been described as a potential therapeutic strategy. We report a case of percutaneous coil embolization of two enlarging left anterior descending pseudoaneurysms arising as a complication of PCI.

Left Anterior Descending Coronary Artery Pseudoaneurysm Compressing the Main Pulmonary Artery in a Patient with Behçet's Disease

Behçet's disease is a systemic inflammatory vascular disorder that may affect the cardiovascular system. Left anterior descending (LAD) artery aneurysm is a rare but potentially fatal complication of Behçet's disease. An accurate diagnosis of this clinical entity requires multimodal imaging (computerized tomography, angiography, and echocardiography) and is essential to guide appropriate therapeutic management. We report the case of a 22-year-old female with LAD pseudoaneurysm who underwent surgical repair with transesophageal echocardiography guidance. We describe the importance of the use of an alternative view to define the origin and location of this unusual pathology.
