Quadricuspid aortic valve (QAV) is a rare congenital heart disease. The functional status of QAV is predominantly a pure aortic regurgitation. Clinical manifestations of patients with a QAV depend on the functional status of the QAV and the associated disorders. Significant valvular regurgitation and (or) stenosis is often present with subsequent operation performed at the fifth to sixth decade of life. The functional status of QAV is predominantly regurgitant; whereas pure stenotic QAV can be as few as in only 0...

BACKGROUND: Postmortem imaging (PMI) refers to the imaging of cadavers by computed tomography (CT) and/or magnetic resonance imaging (MRI). Three cases of cerebral infarctions that were not found during life but were newly recognized on PMI and were associated with severe systemic infections are presented. CASE PRESENTATIONS: An 81-year-old woman with a pacemaker and slightly impaired liver function presented with fever. Imaging suggested interstitial pneumonia and an iliopsoas abscess, and blood tests showed liver dysfunction and disseminated intravascular coagulation (DIC)...

The use of transcatheter aortic valve replacement (TAVR) for high-risk patients with aortic stenosis has rapidly increased during the past years. Accordingly, more and more patients are referred for a follow-up echocardiographic study after TAVR. However, the echocardiographic evaluation of patients who underwent TAVR places specific demands on echocardiographers. Furthermore, TAVR may be associated with new types of complications, which are frequently unrecognized or underestimated due to lack of familiarity with the normal and pathological appearance of TAVR...

In patients with a small aortic root undergoing aortic valve replacement (AVR), the Freedom SOLO bioprosthesis may be the ideal prosthesis because of its stentless design and supra-annular implantation. This study investigated if the stentless Freedom SOLO has an advantage when compared with a stented bioprosthesis in patients with a small aortic root. From April 2005-July 2014, 269 consecutive patients underwent AVR with either a Freedom SOLO (n = 76) or Mitroflow (n = 193) bioprosthesis size 19mm or 21mm, respectively...

The brucellosis with multi-organ involvement in a patient with a history of the composite aortic graft (Bentall procedure) and Hepatitis B infection is rare. A 35-year-old man presented to us with fever and loss of consciousness. Four years ago, he was IDU and underwent cardiac surgery because of endocarditis. Recently lumbar spondylodiscitis was diagnosed. The Wright (1/320) and Coombs Wright tests (1/640) were positive. After CNS imaging, lumbar puncture was done. The CSF pleocytosis was lymphocyte dominant...

The case is presented of a 72-year-old male patient suffering from active infective aortic prosthetic endocarditis two months after emergency surgery with aortic valve implantation, and who underwent aortic arch reconstruction using a Dacron patch, due to the spontaneous post-procedural migration of a transcatheter-implanted aortic valve. The heart team considered transcatheter valve implantation (TAVI) due to the increased operative risk demonstrated by a EuroSCORE II of 10.9%, including chronic obstructive pulmonary disease (GOLD 3), cirrhosis (Child-B), esophageal varicose stage 2, chronic renal failure stage 3, and reduced left ventricular ejection fraction...

BACKGROUND: Increasing antibiotic resistance warrants therapeutic alternatives. Here we investigated the efficacy of bacteriophage-therapy (phage) alone or combined with antibiotics against experimental endocarditis (EE) due to Pseudomonas aeruginosa, an archetype of difficult-to-treat infection. METHODS: In vitro fibrin-clots and rats with aortic EE were treated with an anti-pseudomonas phage cocktail alone or combined with ciprofloxacin. Phage pharmacology, therapeutic efficacy, and resistance were determined...

Aortic root reconstruction in the setting of redo aortic valve procedures or infective endocarditis may be technically challenging, particularly because of variable destruction or distortion of the left ventricular outflow tract. Homograft aortic root replacement is an excellent option for aortic root abscesses but is limited by homograft availability. We describe a simple technique of a bioprosthetic valved conduit constructed on the table using a Dacron (DuPont, Wilmington, DE) skirt below the valve. The use of the Dacron skirt facilitates easy reconstruction of the left ventricular outflow tract...

We report a rare case of prosthetic valve fungal endocarditis caused by Lichtheimia, a subspecies of the order Mucorales. The patient experienced complicated prosthetic valve endocarditis less than 2 months after uneventful coronary artery bypass grafting (CABG) and 2 aortic valve replacements. Ultimately surgical management required aortic root replacement and lifelong antimicrobial agents. We believe this is the first case of fungal endocarditis caused by Lichtheimia.

Endocarditis associated with dialysis catheter is a disease that must be suspected in every patient with hemodialysis who develops fever. Multiple valve disease is a severe complication of endocarditis that needs to be managed in a different way. There is very limited data for treatment and every case must be considered individually. We present a patient with this complication and describe the medical treatment and surgical management. We report the case of a 15-year-old patient with acute renal failure that develops trivalvular endocarditis after the hemodialysis catheter was placed, with multiple positive blood culture for Staphylococcus aureus...

Aortic valve infective endocarditis (IE) can be complicated with severe aortic regurgitation (AR) jet-related lesions such as vegetations, pseudoaneurysms, aneurysms or perforations on the anterior mitral leaflet. Herein is reported the case of a 69-year-old male with culture-negative aortic valve endocarditis complicated with aortic valve perforations resulting in severe and eccentric AR and an AR jet-related ventricular septal defect (VSD). Neither transthoracic echocardiography (TTE) nor two-dimensional transesophageal echocardiography (2D-TEE) were unable to clearly discriminate an aorto-right ventricular fistula from a VSD...

Propionibacterium acnes is known to be a causative microorganism in low-grade and late prosthetic valve endocarditis. Here, the case is reported of a late, apparently culture-negative endocarditis of an aortic mechanical prosthesis, diagnosed to be caused by P. acnes after pan-bacterial polymerase chain reaction (PCR) on the explanted mechanical prosthetic valve. This endocarditis was complicated by an aortic root abscess; after surgical resection a ventricular septal defect (VSD) with overt right ventricular and multiple organ failure occurred...
