1/13. Giant blood cyst of the mitral valve.We report a rare case of giant blood cyst originating from the anterior mitral valve leaflet and chordae tendineae, which was incidentally discovered during a 2-dimensional echocardiography examination performed for assessment of left ventricular function after an uncomplicated myocardial infarction in a 50-year-old man.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/13. Congenitally unguarded tricuspid valve orifice with a giant right atrium and a massive clot in an asymptomatic adult.Congenitally unguarded tricuspid valve orifice, a variant of tricuspid valve dysplasia, is a rare malformation with protean manifestations. This report describes an asymptomatic adult who, on echocardiographic examination ordered in view of an abnormal 12-lead surface electrocardiogram and plain chest X-ray, was found to have an unguarded tricuspid valve orifice with a giant right atrium (12 x 10 cm), intense spontaneous echo contrast and a large right atrial clot.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
3/13. Aortic root pseudoaneurysm following surgery for aortic valve endocarditis.Prosthetic aortic valve replacement for aortic valve endocarditis remains a primary practice of most cardiac surgeons. Usually it cures endocarditis and restores cardiac function. However, in advanced aortic valve endocarditis with complex annular destruction, complications following prosthetic aortic valve replacement do occur and present a formidable challenge for reoperation. Herein, we describe a case of an adult man who was operated on initially for advanced aortic valve endocarditis with a large periannular abscess cavity and who developed congestive heart failure 3 months later. Furthermore, he was diagnosed with a giant pseudoaneurysm around the aortic root without evidence of recurrent infection or aortic prosthetic incompetence. During his reoperation, a cryopreserved aortic homograft as a root replacement that included reimplantation of bilateral coronary artery buttons was used to exteriorize this pseudoaneurysm and reconstruct a left ventricular outflow tract. The postoperative course was unremarkable, and the patient, during a follow-up of 2 years, remained in new york Heart association functional class I. Aortic root pseudoaneurysm following prosthetic aortic valve replacement for infective endocarditis is rare in clinical practice and can cause rapid hemodynamic deterioration which requires imminent reoperation. Homograft aortic root replacement has proven to be a versatile treatment option of this complex disease.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
4/13. giant cell arteritis confined to intramural coronary arteries. Unforeseen hazards myocardial protection.A 74-year-old woman underwent elective double valve replacement (aortic and mitral) for rheumatic valvular disease. She failed to wean from cardiopulmonary bypass due to marked left ventricular dysfunction. At autopsy, severe giant cell arteritis confined to the intramural coronary arteries was seen. Furthermore, there were multiple areas of recent microscopic myocardial infarction around the intramural coronary arteries. This report describes a rare case of giant cell arteritis confined to intramural coronary arteries which lead to inadequate myocardial protection at the time of surgery.- - - - - - - - - - ranking = 2keywords = giant (Clic here for more details about this article) |
5/13. Giant vegetation of the mitral valve simulating primary cardiac tumor.A case of a giant vegetation of the mitral valve causing sudden death of the patient is reported. The case underlines that urgent removal of a big mass must always be considered because of the risk of sudden death or catastrophic embolism. Echocardiographic differential diagnosis of a mass is discussed and is crucial for the choice of the strategy.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
6/13. Persistent sinus venosus valve mimicking pulmonary stenosis and atrial tumor.A case of giant remnant of the right sinus venosus valve simulating first a pulmonary stenosis and afterward a left atrial tumor is described.

7/13. Subacute bacterial endocarditis presenting as polymyalgia rheumatica or giant cell arteritis.OBJECTIVE: To report on several patients with subacute bacterial endocarditis who were initially presumed, incorrectly, to have polymyalgia rheumatica or giant cell arteritis. methods: We report 3 cases of subacute streptococcal endocarditis mimicking giant cell arteritis in 2 cases and polymyalgia rheumatica in one. We reviewed the literature through medline search of French and English-language articles published between 1966 and 2005 and found 5 similar cases. RESULTS: shoulder and/or pelvic girdle pain was associated with neck or back pain in all patients. scalp tenderness, bilateral jaw pain, amaurosis fugax were present in 2 patients. One patient had no fever. Two patients were treated with corticosteroids with initial good clinical response in one. Appropriate antibiotic therapy resulted in the rapid disappearance of rheumatic complaints in 2 patients and achieved a definitive cure of endocarditis in all cases. CONCLUSION: Rheumatologic symptoms may hinder the correct diagnosis of infective endocarditis in patients who present with a clinical picture suggesting polymyalgia rheumatica or giant cell arteritis. In such cases, blood cultures should be systematically drawn.- - - - - - - - - - ranking = 7keywords = giant (Clic here for more details about this article) |
8/13. Granulomatous aortic valvulitis associated with aortic insufficiency in Takayasu aortitis.We report an unusual case of Takayasu aortitis associated with a giant cell granulomatous valvulitis presenting with aortic insufficiency. Although nonspecific valvular abnormalities have been reported with Takayasu aortitis, this case is the first to describe involvement of the aortic valve by the disease.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
9/13. Pseudoaneurysm of an aortic homograft.False aneurysms of the thoracic aorta constitute one of the most challenging problems encountered by the cardiac surgeon. We report a case of successful reoperation for a giant pseudoaneurysm of an aortic homograft, previously used in the context of postpartum acute endocarditis of the aortic valve.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
10/13. Retraction of bioprosthetic heart valve cusps: a cause of wide-open regurgitation in right-sided heart valves.Most failures of bioprosthetic heart valves in children are due to stenosis secondary to thrombus, calcific deposits, or tissue ingrowth. Valve failures due to regurgitation typically involve cuspal detachment, tears, or perforations. We present four cases of prosthetic valve regurgitation in children caused by cuspal retraction without stenosis and describe the morphologic findings related to the valves at autopsy or explantation. A mononuclear cell and giant cell response to the cusps of the valve was a striking finding in one patient.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
