BACKGROUND: To investigate epidemiological trends of infective endocarditis (IE) in western Norway a retrospective study was performed. METHODS: Characteristics of 706 IE admissions from 1996 to 2005 and 2006 to 2015 were analysed and compared using the Chi-square test for categorical variables and the t-test for age. Survival was analysed by multiple Cox regression and reported by the hazard ratio (HR). RESULTS: Mean annual incidence rates increased from 4...

This study describes infection of intestinal smooth muscle in fringelip mullets Crenimugil crenilabis with Kudoa crenimugilis n. sp. Of 30 individuals sampled from the Red Sea off Saudi Arabia, 6 (20%) were infected. Ovoid plasmodia (279-412 × 157-295 µm) in the smooth muscle of the intestine were packed with only mature myxospores with 4 valves. Specifically, light and transmission electron microscopy revealed quadrate myxospores with 4 equal, rounded, spore valves uniting at thin delicate suture lines. The mature myxospores were 8 (7-9) µm long, 5...

To compare reverse left ventricular (LV) remodeling after transcatheter aortic valve replacement (TAVR) between patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV). We retrospectively reviewed data of patients with at least two serial echocardiographic follow-ups (1, 3, 6 months and 1 year) post-TAVR. A total of 116 patients were identified. BAV morphology was documented in 67 patients. LV mass index (LVMi) at baseline was not significantly different between the TAV and BAV group (178...

Background: Transcatheter aortic valve implantation (TAVI) has become the standard treatment for patients with severe symptomatic aortic stenosis (AS) considered at very high risk for surgical aortic valve replacement. The purpose of this sub-study was to evaluate long-term (> 4 years) health-related quality of life (QoL) in octogenarians who underwent TAVI. Methods: A single center observational registry in twenty patients who underwent frame analysis assessment ≥ 4 years after TAVI...

BACKGROUND: Aortic stenosis is accompanied by progressive left ventricular hypertrophy and fibrosis. We investigated the natural history of these processes in asymptomatic patients and their potential reversal post-aortic valve replacement (AVR). METHODS: Asymptomatic and symptomatic patients with aortic stenosis underwent repeat echocardiography and magnetic resonance imaging. Changes in peak aortic-jet velocity, left ventricular mass index, diffuse fibrosis (indexed extracellular volume), and replacement fibrosis (late gadolinium enhancement [LGE]) were quantified...

BACKGROUND: Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary anomaly. The enlarged right coronary artery provides retrograde collaterals to supply the left ventricle then preferentially directs into the lower pressure pulmonary artery system causing coronary steal phenomenon. Few patients who survive through adulthood without surgery must have abundant, well-formed functioning collaterals with adequate perfusion of the left ventricle...

BACKGROUND: Development of carcinoid heart disease (CHD) is the major negative prognostic factor in patients with the carcinoid syndrome. The only effective treatment is valve replacement. However, the selection of candidates and determination of optimal timing remain unclear. Considerable variability in local screening and treatment strategies exist. METHODS: In this single-centre study, we retrospectively analysed the diagnostic process and outcome of all CHD patients who underwent valve surgery between 2000 and 2016...

OBJECTIVE: This study sought to analyze outcomes in patients with moderate-severe tricuspid regurgitation (TR) undergoing transcatheter aortic valve replacement (TAVR). The consequences of uncorrected significant TR in patients undergoing TAVR remain undefined. METHODS: Between 2009 and 2014, 369 patients underwent TAVR at our institution, and 58 of these had baseline moderate-severe TR. Preoperative, 30-day, and 1-year transthoracic echocardiograms were analyzed...

OBJECTIVE: Surgical management of aortic valve infective endocarditis (IE) with cryopreserved homograft has been associated with lower risk of recurrent IE, but there is equipoise with regard to the optimal prosthesis. This systematic review and meta-analysis were performed to compare outcomes between homograft and conventional prosthesis for aortic valve IE. METHODS: We searched MEDLINE database to September 2017 for studies comparing homograft versus conventional prosthesis...

OBJECTIVE: Aortic valve-in-valve implantation for prosthetic valve dysfunction is a good alternative to reoperative valve replacement. There are some limitations to this approach including the risk of coronary occlusion, patient prosthesis mismatch, and valve malposition. The incidence of coronary occlusion is higher in aortic valve-in-valve than de novo aortic stenosis cases. Multiple factors can contribute to this complication, and the type of bioprosthesis has been implicated. METHODS: We examined our experience of 80 aortic valve-in-valve cases with internally and externally mounted leaflet valves...

OBJECTIVES: Left atrial appendage thrombus (LAT) was an exclusion criterion in the seminal transcatheter aortic valve replacement (TAVR) trials; however, such patients do undergo TAVR in the 'real-world' setting. This study sought to analyse outcomes after TAVR in patients with LAT or spontaneous echo contrast (SEC). METHODS: All patients undergoing TAVR at our institution between March 2009 and December 2014 were prospectively analysed. The presence of LAT or SEC was determined via a retrospective chart review...

OBJECTIVES: The Ross procedure involves replacing a patient's diseased aortic valve with their own pulmonary valve. The most common failure mode is dilatation of the autograft. Various strategies to reinforce the autograft have been proposed. Personalized external aortic root support has been shown to be effective in stabilizing the aortic root in Marfan patients. In this study, the use of a similar external mesh to support a pulmonary artery autograft was evaluated. METHODS: The pulmonary artery was translocated as an interposition autograft in the descending thoracic aortas of 10 sheep...

OBJECTIVE: The aim of this study was to compare outcomes after rapid-deployment aortic valve replacement (RDAVR) and conventional aortic valve replacement (AVR) from two studies. METHODS: Patients who underwent RDAVR (INTUITY valve) in the prospective, 5-year, single-arm multicenter TRITON study, or conventional AVR (Perimount Magna Ease valve) in the prospective Perimount Magna Ease postmarket study, were propensity score matched and compared for procedural, hemodynamic, safety, and clinical outcomes...

Transcatheter aortic valve implantation is a suitable therapeutic intervention for patients deemed inoperable or high risk for surgical aortic valve replacement. Current investigations question whether it is a suitable alternative to surgery for intermediate- and low-risk patients. The following meta-analysis presents a comparison between transcatheter versus surgical aortic valve replacement in patients that are intermediate and low risk for surgery. Articles were collected via an electronic search using Google Scholar and PubMed...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is an alternative to surgical aortic valve replacement (SAVR) for the treatment of aortic stenosis in patients at intermediate, high, and extreme risk for mortality from SAVR. We examined recent trends in aortic valve replacement (AVR) in Michigan. METHODS: The Michigan Society of Thoracic and Cardiovascular Surgeons Quality Collaborative (MSTCVS-QC) database was used to determine the number of SAVR and TAVR cases performed from January 2012 through June 2017...

BACKGROUND: In patients with repaired tetralogy of Fallot (TOF), a better understanding of the impact of surgical pulmonary valve replacement (PVR) on ventricular mechanics may lead to improved indications and outcomes. Therefore, we used cardiovascular magnetic resonance (CMR) feature tracking analysis to quantify ventricular strain and synchrony in repaired TOF patients before and after PVR. METHODS: Thirty-six repaired TOF patients (median age 22.4 years) prospectively underwent CMR a mean of 4...

OBJECTIVES: The aim of this study was to study differences in progression of aortic stenosis (AS) in patients with mediastinal radiotherapy (XRT)-associated moderate AS versus a matched cohort during the same time frame, and to ascertain need for aortic valve replacement (AVR) and longer-term survival. BACKGROUND: Rate of progression of XRT-associated moderate AS and its impact on outcomes is not well-described. METHODS: We included 81 patients (age 61 ± 13 years; 57% female) with at least XRT-associated moderate AS (aortic valve area [AVA] 1...
