RATIONALE: Endocarditis with Abiotrophia defectiva represents 4.3% to 6% of all streptococcal endocarditis. The article presents diagnosis issues and the complexity of the treatment. PATIENT CONCERNS: We present the case of a female white patient, aged 26 years, who developed infectious endocarditis caused by A defectiva, in the last trimester of pregnancy, a biofilm-related infection associated with the presence of fixed braces. DIAGNOSES: The diagnosis of infectious endocarditis was confirmed by the cardiac ultrasound examination that revealed a voluminous vegetation on the mitral valve, and acute mitral regurgitation caused by chordae tendinae rupture, and also by isolating Abiotrophia defectiva from two positive blood cultures...

PURPOSE: To determine the time point at which thrombocytopenia after TAVI procedure is an indicator of the worst prognosis, with special consideration of perioperative platelet and coagulation activation as its potential causes. METHODS: Thirty two patients (mean age 78.5±7.9years, 62% females) qualified for TAVI procedure were prospectively evaluated. Platelet counts were assessed at baseline and for the next three postoperative (POD) days. Platelet activation was evaluated by P-selectin (PS, serum, ELISA) and platelet factor 4 (PF-4, CTAD plasma), and blood coagulation activation by prothrombin fragments 1+2 (F1+2, plasma, ELISA)...

Although occlusion of the coronary arteries during transcatheter aortic valve replacement is rare, the mortality is high. In this review, we discuss the prevention and management of this complication. Occlusion of coronary ostia is a very rare, but serious, complication of transcatheter aortic valve replacement (TAVR). Although reported as only occurring in <1% of TAVR cases, it carries a high risk of fatality, with some series reporting a mortality rate as high as 40%. We present the management of an occluded left coronary artery after a self-expanding TAVR, and review the incidence, prevention, and management of this complication...

BACKGROUND AND AIM OF THE STUDY: Outcomes after repair of tetralogy of Fallot (TOF) are good with either a transventricular (TV) or transatrial (TA) approach. We sought to determine if there is a relationship between the TV or TA approach and right ventricular (RV) function, and the role of residual pulmonary regurgitation (PR) on the long-term outcomes. METHODS: This was a retrospective cohort multicentric study on survivors after surgical repair of TOF (TA versus TV approach, ±transannular patch) between 1990 and 2004...

We describe a case of a 69-year-old female referred for the evaluation of exertional dyspnea, with a small membranous ventricular septal defect (VSD) and right ventricle (RV) outflow tract obstruction. Using transthoracic echo was diagnosed VSD with left to right shunting and transesophageal echo (TEE) was used to a better anatomical characterization. TEE showed a perimembranous subaortic VSD that developed a high-velocity flow in RV. Pulmonary valve appears normal and right ventricular infundibular hypertrophy or double-chambered RV was excluded from the study...

A 74-year-old male presented to the emergency department 46 days after undergoing an aortic valve replacement. He presented with nonspecific symptoms developed over the previous 15 days, with a new onset of a systolic panfocal murmur. Echocardiography revealed a great vegetation measuring 15 mm by 23 mm causing a severe obstruction of the bioprosthesis. The patient underwent an emergency surgical procedure due to his hemodynamic unsteadiness. During the procedure, we noted an obstruction of the left ventricle outflow tract with pseudoaneurysm of the aortomitral continuity...

A 7-year-old girl with an episode of hematochezia and melena, suspicious for bleeding Meckel's diverticulum, was referred for a Tc-99m pertechnetate Meckel's scan. On dynamic planar scan, apart from prompt gastric visualization an oval-shaped, area of inhomogeneous tracer uptake was observed in the left lower quadrant of the abdomen. Subsequent single-photon emission computed tomography/computed tomography localized this to intestinal lumen, thus establishing the diagnosis of intestinal duplication (ID) with functional gastric mucosa...

Numerous studies over past four decades have implicated a strong association of Streptoccus bovis infection with colorectal carcinomas. Strong is this association that a screening colonoscopy for identifying malignancy is considered mandatory in patients whose blood/fecal cultures show growth of this particular pathogen. Here, we report an interesting case of a 61-year-old female patient who presented with pyrexia of unknown origin for 3 weeks. Positron emission tomography/computed tomography, in addition to helping diagnose mitral valve endocarditis, also identified a clinically occult T2N0 rectal carcinoma...

Seismocardiogram, SCG, is the measure of precordial vibrations produced by the beating heart, from which cardiac mechanics may be explored on a beat-to-beat basis. We recently collected a large amount of SCG data (>69 recording hours) from an astronaut to investigate cardiac mechanics during sleep aboard the International Space Station and on Earth. SCG sleep recordings are characterized by a prolonged duration and wide heart rate swings, thus a specific algorithm was developed for their analysis. In this article we describe the new algorithm and its performance...

The ability of animals to cope with environmental stress depends - in part - on past experience, yet knowledge of the factors influencing an individual's physiology in nature remains underdeveloped. We used an individual monitoring system to record body temperature and valve gaping behavior of rocky intertidal zone mussels (Mytilus californianus). Thirty individuals were selected from two mussel beds (wave-exposed and wave-protected) that differ in thermal regime. Instrumented mussels were deployed at two intertidal heights (near the lower and upper edges of the mussel zone) and in a continuously submerged tidepool...

BACKGROUND: Mitral para-prosthetic leaks are rare but major complications of mitral heart valve replacements. When they must be re-operated, they are burdened with high mortality rates. We propose to review our surgical experience in terms of approach and type of operation carried out. METHODS: Demographic, preoperative, intraoperative and postoperative characteristics of 34 patients who benefited from a surgical treatment of mitral paravalvular leak at the Brugmann University Hospital between 1996 and 2016 have been gathered retrospectively...

Background: Q fever is a worldwide zoonosis caused by Coxiella burnetii. In some persons, particularly those with cardiac valve disease, infection with C. burnetii can cause a life-threatening infective endocarditis. There are few descriptive analyses of Q fever endocarditis in the United States. Methods: Q fever case report forms submitted during 1999-2015 were reviewed to identify reports describing endocarditis. Cases were categorized as confirmed or probable using criteria defined by the Council for State and Territorial Epidemiologists (CSTE)...

Paraneoplastic hepatopathy has been reported with various malignancies, most commonly with renal cell cancer. This non-metastatic hepatic dysfunction in such malignancies is known as Stauffer syndrome. We describe a 61-year-old man who presented with symptoms of bowel obstruction with marked cholestasis and high levels of alkaline phosphatase and bilirubin. Imaging revealed an unremarkable liver and a mass in the ileocecal valve with mesenteric lymphadenopathy. Biopsies were consistent with a carcinoid tumor...
