Introduction.Listeria monocytogenes is a rare etiology of infectious endocarditis with only 30 cases of prosthetic valve and about twice as many native valve infections described in the literature. We describe an unusual presentation of an endovascular embolic phenomenon with associated lower extremity mycotic aneurysm due to Listeria monocytogenes prosthetic aortic valve and aortic endograft infection. Case presentation. This is a case of an elderly gentleman with prior history of bioprosthetic aortic valve placement and aortic arch repair who was admitted with several weeks of constitutional symptoms and left lower leg pain...

The Ross procedure is an alternative option for young and middle-aged patients needing aortic valve replacement. We present an interesting case where the patient had a preexisting aortic homograft that was implanted because of previous infective endocarditis with aortic root abscess. The patient presented with biological degeneration of the homograft with resultant severe stenosis as well as insufficiency. We performed a redo root surgery to replace the homograft with the Ross procedure by using the autograft inclusion into a vascular graft technique...

Subacute bacterial endocarditis can have many different presentations; in rare instances, it can present as leukocytoclastic vasculitis owing to the effect of circulating immune complexes and micro-emboli on the vascular endothelium. A high index of suspicion needs to be maintained to differentiate between infectious vs noninfectious autoimmune vasculitides, keeping in mind that missing a diagnosis can have fatal results. In this case report, we introduce a young female patient who initially presented with a picture of idiopathic autoimmune cutaneous vasculitis delaying the diagnosis of an underlying infective endocarditis with aortic valve involvement...

BACKGROUND: We analyzed our early and midterm results with aortic valve reimplantation surgery to determine the influence of Marfan syndrome and bicuspid valves on outcomes with this technique. METHODS: Between March 2004 and December 2015, 267 patients underwent aortic valve reimplantation operations. The mean diameter of the sinuses of Valsalva was 50 ± 3 mm and moderate/severe aortic regurgitation was present in 34.4% of these patients. A bicuspid aortic valve was present in 21% and 40% had Marfan syndrome...

A 54-year-old female patient presented to her local district general hospital with a painful, swollen left arm. Imaging revealed an ulnar artery aneurysm. The aetiology was embolic, with an echocardiogram revealing vegetations on the aortic valve. The patient was treated empirically for 6 weeks with amoxicillin and gentamicin for endocarditis. Eight months later, she had an elective aortic valve replacement for symptomatic aortic regurgitation. The valve was culture negative but analysis by 16S rDNA PCR was positive for Tropheryma whipplei In retrospect, the ulnar artery aneurysm and a history of arthralgia were attributed to an underlying diagnosis of Whipple's endocarditis...

Transcatheter aortic valve replacement (TAVR) has revolutionized the treatment of symptomatic aortic stenosis. The number of TAVR procedures is expected to increase exponentially in the next decade. Therefore, patients will inevitably present with signs and symptoms attributable to TAVR bioprosthesis failure many years after an acutely successful procedure. Their management will become increasing important moving forward. Areas covered: The aim of this article is to review the causes of bioprosthesis failure and outline optimal management strategies in elderly patients...

Best timing for permanent pacemaker implantation to treat complete atrioventricular block (AVB) after cardiac surgery is unclear, as late pacemaker dependency was found low in recent observational studies. This study aimed to identify factors associated with spontaneous recovery from AVB. In a prospective and observational cohort, all patients who underwent cardiothoracic surgery during a 14-month-period were included (n = 1,200). Risk factors of postoperative AVB were assessed by logistic regression. Among patients who developed AVB, variables associated with recovery from AVB were assessed by Cox and logistic regression...
