Treatment and Imaging Modalities of Giant Coronary Aneurysms Resulting from Kawasaki Disease and Presenting as Acute Inferior Wall Myocardial Infarction.

Giant coronary aneurysms are late sequelae of Kawasaki disease (KD). We describe a 53-year-old patient who presented with acute myocardial infarction and proximal aneurysms of all three coronary arteries. Coronary angiography demonstrated the aneurysms, but CT angiography allowed accurate assessment of the real dimensions of the aneurysms and making the decision on the preferred method of revascularization. The patient underwent coronary bypass surgery and is asymptomatic at follow-up.

Primary cardiac chondrosarcoma with rapid MFH-like recurrence: case report and review of tumor type.

We present a case report of a patient with a rare primary cardiac tumor, chondrosarcoma. After initial excision, a locally advanced recurrence appeared within six weeks at a different site in the heart with the histological features of a high-grade sarcoma. We discuss the background, management and prognosis of these rare tumors.

Rapidly Progressive Bioprosthetic Aortic Valve Stenosis Due to Bartonella Species Endocarditis.

Rapid progression of valvular stenosis in the setting of infective endocarditis is extremely rare. Here we describe a patient with Bartonella endocarditis on a bioprosthetic aortic valve that caused rapidly progressive aortic stenosis without regurgitation. At operation the bioprosthetic valve was severely fibrotic and calcified, with markedly thickened and distorted leaflets and circular partial detachment from the aortic ring. The patient underwent aortic root replacement with aortic bioprosthesis and aortic grafting with reimplantation of the coronary ostia.
