Huge saphenous vein graft aneurysm presenting as non-ST elevation myocardial infarction and compressing the heart.

ABSTRACT: Coronary artery bypass grafting (CABG) surgery maintains an important role in the treatment of coronary artery disease. The huge saphenous vein graft aneurysm (HSVGA) is rare and occurs as a late complication after CABG. Here, we reported a case of HSVGA presenting as non-ST elevation myocardial infarction.

Rapidly expanding saphenous vein graft myoctic aneurysm causing ST-elevation myocardial infarction: a case report.

Project description:BackgroundMycotic aneurysms of coronary vein grafts are rare and associated with high mortality. They are most commonly a result of surgical or percutaneous intervention, and present with complications including myocardial infarction (MI), infective endocarditis. A recent literature review identified 97 cases of mycotic coronary aneurysms in total.Case summaryA 49-year-old man with a history of coronary artery bypass grafting and septic arthrithis presented with chest pain and fevers and ST elevation on electrocardiogram. Urgent angiogram showed an aneurysmal saphenous vein graft from the PL branch to PDA-no acute intervention was performed due to concern about bacteraemia. Methicillin-sensitive Staphylococcus aureus was grown in urine and blood but no focus of infection was identified. Despite treatment with antibiotics and antiplatelets, the patient returned with evidence of expansion of the SVG aneurysm requiring surgical resection.DiscussionThis case highlights the difficulty in treating acute coronary syndromes involving mycotic aneurysms. Multimodal imaging approaches are useful to identify suspected infection, but false negatives occur. Due to high risk of rupture or haemorrhage, there are limited options for urgent reperfusion in cases of MI with mycotic aneurysm, demonstrating the need for an individualized approach and close follow-up.

Percutaneous closure of giant saphenous vein graft aneurysm.

Project description:BackgroundAneurysmal dilatation of saphenous vein grafts used for coronary artery bypass grafting is a rare complication. These aneurysms are often large in calibre and pose a risk of rupture with significant haemorrhage.Case summaryWe describe a case whereby a large saphenous vein graft aneurysm is closed percutaneously using a vascular plug to cease flow and promote thrombosis of the aneurysm whilst reconstructing the occluded native artery to negate ischaemia.ConclusionSaphenous vein graft aneurysms following coronary artery bypass graft are rare and late complications. The preferred modality of closure is via percutaneous approach that requires meticulous planning to achieve a good outcome.

"Floating" Stent in a Coronary Aneurysm Presenting as ST-Elevation Myocardial Infarction.

Project description:Coronary artery aneurysm (CAA) presenting as an ST-elevation myocardial infarction (STEMI) represents a clinical challenge due to the technical difficulties in the percutaneous management of this specific situation. Appropriate treatment for CAA depends on the precise clinical situation and consists of medical management, surgical resection, or/and stent placement. The high rate of complications during percutaneous intervention (distal thrombus embolization, no-reflow phenomenon, stent malposition, or dissection) makes emergent surgery a frequent situation in these cases. We present the case of a 50-year-old man with a STEMI due to thrombotic occlusion of CAA. Specific angiographic techniques and intracoronary imaging help with the percutaneous management of acute thrombotic occlusions in CAA, providing a less invasive approach than emergent surgery.

Unconventional treatment of a giant coronary aneurysm presenting as ST-elevation myocardial infarction: a case report.

Project description:BackgroundThe optimal treatment of aneurysmal or ectatic culprit vessels in the setting of acute myocardial infarction is still matter of debate, as revascularization with either percutaneous intervention or surgery is associated with low procedural success and poor outcomes.Case summaryWe report the case of a 55-year-old male patient, admitted for inferior ST-elevation myocardial infarction, who underwent successful percutaneous implantation of a micro-mesh self-expanding nitinol carotid stent in a right coronary aneurysm with intravascular ultrasonography measured diameter of 9 mm and massive thrombus apposition.DiscussionThe technical characteristics of the micro-mesh self-expanding nitinol carotid stent allow for adequate plaque coverage and good apposition even in large vessels, making this device particularly suitable for the treatment of coronary lesions with high thrombus burden, when severe coronary ectasia or aneurysms are present.

A case of giant saphenous vein graft aneurysm successfully treated with catheter intervention.

Project description:The patient was a 67-year-old man who had undergone coronary artery bypass graft surgery using a saphenous vein graft (SVG) 22 years before. Computed tomography angiogram revealed a large aneurysm of the SVG (38 × 42 mm in diameter; 80-mm long) and total occlusion of the left anterior descending artery (LAD). We first performed percutaneous coronary intervention for chronic total occlusion of the native LAD with bi-directional approach via the SVG. One month later, we performed the trans-catheter embolization of the SVG and occluded the SVG using multiple coils. This case demonstrates that trans-catheter embolization after recanalization of native coronary artery is an effective strategy to treat an SVG aneurysm. © 2015 Wiley Periodicals, Inc.

"Water running in my chest": Delayed spontaneous rupture of an aortocoronary saphenous vein graft aneurysm.

Project description:Saphenous vein graft aneurysm is an uncommon condition and knowledge about its natural history, and a multi-specialty heart team approach is of utmost importance for better clinical outcomes. This case highlights importance of percutaneous intervention as a viable therapeutic option in the case of saphenous vein graft aneurysms.

ST elevation myocardial infarction.

Project description:ST segment elevation myocardial infarction remains a significant contributor to morbidity and mortality worldwide, despite a declining incidence and better survival rates. It usually results from thrombotic occlusion of a coronary artery at the site of a ruptured or eroded plaque. Diagnosis is based on characteristic symptoms and electrocardiogram changes, and confirmed subsequently by raised cardiac enzymes. Prognosis is dependent on the size of the infarct, presence of collaterals and speed with which the occluded artery is reopened. Mechanical reperfusion by primary percutaneous coronary intervention is superior to fibrinolytic therapy if delivered by an experienced team in a timely fashion. Post-reperfusion care includes monitoring for complications, evaluation of left ventricular function, secondary preventive therapy and cardiac rehabilitation.

Stable Hemodynamics within "No-Touch" Saphenous Vein Graft.

Project description:PURPOSE:To investigate the hemodynamics characteristics of the "no-touch" saphenous vein graft (SVG) conduits by nicardipine intraluminal administration in vivo experiment. METHODS:A total of 59 consecutive patients were enrolled and underwent a sequential SVG to three non-left anterior descending (LAD) targets with the average runoff ≤2 mm, 30 with "no-touch" harvest technique (group A) and 29 with conventional preparation (group B). The patients were subject to nicardipine intraluminal injection during off-pump coronary artery bypass grafting (CABG) procedure. The intraoperative flow was measured with the ultrasonic transit time flow meter (TTFM), and the graft patency testified by multi-detector computed tomography (MDCT) angiography, respectively. RESULTS:The baseline blood flow was higher in group A than that in group B (p <0.05). However, the increases in blood flow of SVG conduits in group A were lower than those in group B with 19.7 ± 5.9 vs. 35.4 ± 9.2 mL/min, 14.8 ± 5.6 vs. 23.1 ± 6.8 mL/min, 6.6 ± 2.1 vs. 11.2 ± 4.3 mL/min before the first, second, and third anastomose after nicardipine intraluminal administration, respectively (all p <0.01). CONCLUSIONS:No-touch SVGs were associated with higher baseline blood flow and less rises after nicardipine intraluminal administration during off-pump CABG procedure compared with conventional preparation. The no-touch SVGs seemed to be less spastic and well-tolerated on flow dilatation.
