Coronary artery bypass grafting for coronary aneurysms due to Kawasaki disease.

We report a 23-year-old man who underwent coronary artery bypass grafting (CABG) for coronary aneurysms associated with Kawasaki disease using the left internal thoracic artery (LITA) and right gastroepiploic artery (RGEA) after a second myocardial infarction (MI). Preoperatively, this patient showed repetitive occlusion and recanalization of coronary artery flow without coronary stenosis. Indication of bypass surgery in Kawasaki disease is usually associated with stenosis. However, even an aneurysm alone should be an indication of surgery if there is any kind of ischemic event.     

Coronary artery bypass grafting in adult coronary artery disease due to suspected Kawasaki disease in childhood

Development of coronary artery aneurysms is one typical complication of Kawasaki disease and can cause coronary artery disease even in early childhood. Information about course and outcome in adults is rare. Here, we present a 49-year-old man with serious three-vessel coronary artery disease and giant coronary artery aneurysms following suspected Kawasaki disease.     

Symptomatic coronary obstruction due to Kawasaki disease in an adult

Kawasaki disease is the most common cause of pediatric ischemic heart disease in the world, but it is unusual in adults. We present a case of Kawasaki disease in a young adult. This 20-year-old man presented with angina. Coronary angiography revealed aneurysmal obstructive lesions consistent with remote Kawasaki disease. The patient underwent coronary artery bypass grafting with arterial conduits. Postoperative echocardiography was normal and stress myocardial perfusion imaging showed no ischemia. He remained asymptomatic 12 months after surgery. There is controversy regarding optimal therapy, choice of conduit, treatment of proximal aneurysms, and surveillance in adults with Kawasaki disease.     

Coronary artery bypass grafting in an adult case with Kawasaki disease.

Surgical revascularization for coronary artery lesions secondary to Kawasaki disease has been rarely reported in adult patients. We reported an adult case with few coronary risk factors but with multiple coronary artery aneurysms and obstructive lesions presumably secondary to Kawasaki disease who underwent coronary artery bypass grafting (CABG) with multiple arterial grafts. The postoperative course was uneventful. Because coronary artery sequelae of Kawasaki disease can be a cause of ischemic heart disease even in adults, heightened awareness of this possibility is required for young adults with coronary lesions but without coronary risk factors.     

Accessory mitral valve leaflet in an adult with coronary artery disease

Accessory mitral valve leaflet is a very rare cause of left ventricular outflow tract obstruction. We report a patient presenting this cardiac abnormality who undergone cardiac surgery. A 60-year-old man, presented coronary artery disease and moderate left ventricular tract obstruction due to accessory mitral valve leaflet. The accessory mitral valve leaflet had the typical morphology of a parachute-shaped attached partially to the anterior mitral valve leaflet, with chordae tendinae attached to: 1) an accessory papillary muscle inserted at the free-wall closed to the apex; 2) interconnected with the chordae tendinae of the anterior mitral valve leaflet; 3) a second accessory papillary muscle inserted to the interventricular septum. He underwent successful coronary revascularization of 2 vessels and accessory leaflet excision. A review of 21 cases with accessory mitral valve leaflet is reported.     

Coronary bypass in an adult with Kawasaki disease

We present the case of a 30-year-old female patient with few coronary risk factors for atherosclerosis but with 3-vessel coronary artery disease possibly secondary to Kawasaki disease. Coronary angiography showed total occlusion of the left anterior descending artery and a right coronary artery aneurysm. Quadruple coronary artery bypass was performed. The postoperative course was uneventful.

Multiple coronary aneurysms due to Kawasaki disease in young man--successful triple coronary bypass grafting by utilizing the right gastroepiploic artery, internal thoracic artery and saphenous vein

A 28-year-old man developed acute anteroseptal myocardial infarction. Emergency coronary angiography revealed multiple coronary aneurysms, associated with complete obstruction of left anterior descending artery (LAD) and 50 to 99% stenosis of the right and the circumflex coronary artery (CX). Coronary artery bypass graftings were performed seven weeks after successful emergency intracoronary thrombolysis. The saphenous vein graft was anastomosed to CX, the internal thoracic artery to LAD, the right gastroepiploic artery to RCA just above the bifurcation. Post-operative course was uneventful. On sixth post operative week cardiac catheterization was performed. The study showed all three bypass grafts and native coronary artery to be patent. The patient is now followed up under anticoagulant therapy.     

Review: surgical treatment of giant coronary aneurysms in pediatric patients with Kawasaki disease

In Kawasaki disease (KD), giant coronary aneurysms in the proximal segments of the coronary arteries have long been among the serious complications associated with acute myocardial infarction. To treat myocardial ischemia in children, Kitamura et al. first performed coronary artery bypass grafting in a pediatric patient using an autologous saphenous vein. In the early 1980s, they began to use the internal thoracic artery (ITA) as a bypass graft to the left anterior descending artery, which later was proven to improve long-term life expectancy with its favorable long-term patency, as well as growth potential. Thus, the excellent characteristics of the ITA have come to be widely known among pediatric cardiac surgeons, and a growing number of coronary bypass surgery procedures using the ITA are now being performed worldwide. Although a longer follow-up with more patients is necessary, downsizing reconstructive procedure may be a treatment of choice for giant aneurysms of non-LAD territories to improve coronary circulation. The efficacy of surgical treatment for giant coronary aneurysms in pediatric patients with Kawasaki disease is now well established. Pediatric coronary artery bypass grafting using the ITA, either single or bilateral, can be safe not only for patients with Kawasaki coronary disease but also for infants with congenital coronary lesions.     

Surgical management of multiple giant coronary artery aneurysms determining myocardial ischemia

Coronary artery aneurysms (CAAs) are rare lesions in which the optimal management is poorly defined. We present a series of three patients with diffuse symptomatic coronary artery disease and giant CAAs, on the circumflex branch (6 × 5 cm - Patient 1), on the proximal right coronary artery (5 × 6 cm - Patient 2) and on the proximal left anterior descending (LAD) (4 × 5 cm - Patient 3). Standard coronary artery bypass grafting (LIMA-on-LAD plus sequential saphenous vein) and associated CAA exclusion by proximal and distal ligation was performed according to the coronary anatomy. Six month follow-up computed tomography scan control showed complete exclusion of the CAA in all three patients.     

Rupture of a giant coronary artery aneurysm due to Kawasaki disease

Coronary artery aneurysm requiring surgery is rare. We report a case of a ruptured giant coronary artery aneurysm due to Kawasaki vasculitis which presented with cardiac arrest and was successfully treated by emergency coronary artery bypass grafting. The controversies surrounding the management of this disease are also discussed.

Minimally invasive coronary artery bypass grafting surgery in a child with Kawasaki disease

An 8-year-old girl with Kawasaki disease underwent surgical revascularization to the left anterior descending coronary artery on the beating heart via a left anterior short thoracotomy. Angiography 21 months after surgery showed excellent graft patency. This case--the first success in minimally invasive surgical coronary artery revascularization in a child in the world--suggests that minimally invasive methods are a reasonable alternative in coronary artery revascularization in a child with Kawasaki disease whose left anterior descending artery is the only requiring it.
