We present our experience for patients who have undergone an anatomic repair (AR) for congenitally corrected transposition of the great arteries (CCTGA) at the Children's Hospital of Wisconsin. A retrospective chart review of patients who underwent AR for CCTGA from 2001 to 2015 was performed. The cohort consisted of 15 patients (74% male). Median age of anatomic repair was 15 months (range 4.5-45.6 months). Four patients had a bidirectional Glenn (BDG) prior to AR. At the time of AR,-9 (60%) underwent Senning/Rastelli procedure, 4 (26...

Takashi Kunihara
The two major valve-sparing root replacement procedures, aortic valve reimplantation (reimplantation) and aortic root remodeling (remodeling), have advantages and disadvantages, which are reviewed herein. The main advantage of reimplantation is the resulting annular support, and the disadvantages are the unfavorable hemodynamics and relatively long procedure time. The main advantages of remodeling are the physiological hemodynamics and decreased procedure time, and the disadvantage is the lack of annular support...

OBJECTIVE: Postoperative cognitive dysfunction is an important complication of cardiac surgery with poor outcomes. Serum glial cell line-derived neurotrophic factor levels are decreased in patients with Alzheimer's disease, but the association between glial cell line-derived neurotrophic factor levels and postoperative cognitive dysfunction is poorly understood. The present study aimed to investigate the prognostic value of postoperative serum glial cell line-derived neurotrophic factor levels to predict postoperative cognitive dysfunction in patients with rheumatic heart disease undergoing heart valve replacement...

PURPOSE: Encapsulation of the Ahmed glaucoma valve (AGV) plate is a common cause for postoperative elevation of intraocular pressure, especially in children. Many reports have described the outcomes of AGV revision in adults. However, the outcomes of AGV revision in children are poorly documented. The aim of this study was to determine the outcomes of AGV revision in children. DESIGN: Retrospective cross sectional study METHODS: A retrospective chart review of patients less than 15 years of age who underwent AGV revision with a minimum postoperative follow-up of six months was conducted...

In this study, a new analytical procedure based on isotachophoresis (ITP) coupled to a multi collector inductively coupled plasma mass spectrometer named Stop-Flow-ITP-MC-ICPMS is developed for exhaustive and high-precision multi-elemental isotopic characterization. We demonstrate that Stop-Flow-ITP makes it possible to stop the analytes migration several times for a duration compatible with the detector configuration changes without losing the separation performance. With this procedure, isotope ratio measurements of four lanthanides of interest for nuclear applications (Nd, Sm, Eu and Gd) were obtained with a reproducibility better than 0...

Jaromir Jarda Ruzicka
Automation of reagent based assays, by means of Flow Injection (FI), is based on sample processing, in which a sample flows continuously towards and through a detector for quantification of the target analyte. The Achilles heel of this methodology, the legacy of Auto Analyzer®, is continuous reagent consumption, and continuous generation of chemical waste. However, flow programming, assisted by recent advances in precise pumping, combined with the lab-on-valve technique, allows the FI manifold to be designed around a single confluence point through which sample and reagents are sequentially directed by means of a series of flow reversals...

OBJECTIVES: This study sought to determine whether mobile health (mHealth) device assessments used as clinical decision support tools at the point-of-care can reduce the time to treatment and improve long-term outcomes among patients with rheumatic and structural heart diseases (SHD). BACKGROUND: Newly developed smartphone-connected mHealth devices represent promising methods to diagnose common diseases in resource-limited areas; however, the impact of technology-based care on long-term outcomes has not been rigorously evaluated...

OBJECTIVES: The objective of this study was to determine the prognostic value of combined measures of B-type natriuretic peptide (BNP) and high-sensitivity cardiac troponin T (hsTnT) in patients with low-flow, low-gradient aortic stenosis (LF-LG AS) who had either a preserved or reduced left ventricular ejection fraction (LVEF). BACKGROUND: An elevated BNP level is associated with increased risk of mortality in patients with LF-LG AS. The incremental prognostic value of hsTnT in these patients is unknown...

OBJECTIVES: The aim of this study was to describe the impact of frailty in patients undergoing percutaneous mitral valve repair (PMVR). BACKGROUND: Frailty is common in elderly patients and those with comorbidities and is associated with adverse prognosis. METHODS: Frailty according to the Fried criteria was assessed in consecutive patients admitted for PMVR. Associations of frailty with 6-week (device success, changes in 6-minute walking distance and Minnesota Living With Heart Failure Questionnaire and Short Form 36 physical and mental component scores, and improvement ≥1 New York Heart Association functional class) and long-term outcomes during a median follow-up period of 429 days were examined...

The objectives of this study were to describe and compare the clinical characteristics and outcomes of patients with definite and possible infective endocarditis (IE) involving prosthetic heart valve, and to identify prognostic factors for long-term mortality, using data from an unselected cohort of consecutive patients. We studied data from 133 consecutive patients with IE involving prosthetic heart valve seen in an academic institution between 1990 and 2012. Patients were classified according to the modified Duke criteria for IE: patients with possible IE (n = 47, 35%) and patients with definite IE (n = 86, 65%)...

REVIEW
Mouhammad Fathallah, Richard A Krasuski
PURPOSE OF REVIEW: Our review is intended to provide readers with an overview of disease processes involving the pulmonic valve, highlighting recent outcome studies and guideline-based recommendations; with focus on the two most common interventions for treating pulmonic valve disease, balloon pulmonary valvuloplasty and pulmonic valve replacement. RECENT FINDINGS: The main long-term sequelae of balloon pulmonary valvuloplasty, the gold standard treatment for pulmonic stenosis, remain pulmonic regurgitation and valvular restenosis...

Afshin Anssari-Benam, Andrea Bucchi
This paper is concerned with proposing a suitable structurally-motivated strain energy function for modelling the deformation of the elastin network within the aortic valve (AV) tissue. The AV elastin network is the main non-collagenous load-bearing component of the valve matrix and therefore, within the context of continuum-based modelling of the AV, it essentially serves as the contribution of the 'isotropic matrix'. To date, such function has mainly been considered as either a generic neo-Hookean term or a general exponential function...

BACKGROUND AND PURPOSE: The incidence of periprocedural brain infarcts varies among cardiovascular procedures. In a systematic review, we compared the ratio of radiographic brain infarcts (RBI) to strokes and transient ischemic attacks across cardiac and vascular procedures. METHODS: We searched MEDLINE and 5 other databases for brain infarcts in aortic valve replacement, coronary artery bypass grafting, cardiac catheterization, and cerebral angiogram through September 2015...

BACKGROUND: Gait speed reflects an important factor of frailty and is associated with an increased risk of late mortality in patients with cardiac disease. This study sought to assess the prognostic value of gait speed in elderly patients who underwent transcatheter aortic valve replacement. METHODS AND RESULTS: We investigated the 5-m or 15-feet gait speed (m/sec) in 1256 patients who underwent transcatheter aortic valve implantation using data from the OCEAN-TAVI Japanese multicenter registry (Optimized Catheter Valvular Intervention-Transcatheter Aortic Valve Implantation)...
