#1
David B Rivers, Andrew McGregor
The morphological characteristics of artifacts from five species of necrophagous flies were examined following feeding on several types of diets. Four types of insect stains were produced by each species: regurgitate, defecatory, translocation, and tarsal tracks. Regurgitate was the most frequent type deposited (70.9 ± 2.4%), followed by defecatory (19.8 ± 4.0%), tarsal tracks (8.6 ± 1.2%), and translocation (0.7 ± 0.1%). Artifact shapes, sizes, and color were highly variable and species and diet specific...

BACKGROUND: The Chicago Classification (CC) uses high-resolution manometry (HRM) software tools to designate esophageal motor diagnoses. We evaluated changes in diagnostic designations between two CC versions, and determined motor patterns not identified by either version. METHODS: In this observational cohort study of consecutive patients undergoing esophageal HRM over a 6-year period, proportions meeting CC 2.0 and 3.0 criteria were segregated into esophageal outflow obstruction, hypermotility, and hypomotility disorders...

OBJECTIVES: If the aortic root dilates after native aortic valve-sparing root reconstruction with remodeling, aortic regurgitation may recur. However, it has not been demonstrated clearly that the aortic root dilates after remodeling. METHODS: This study enrolled 15 patients who underwent an aortic valve-sparing operation with remodeling (2002-2014) but without any ventriculo-aortic junction (VAJ) fixation. Technically, special care was taken to pass the sutures through the fibrous annulus...

Besides providing spatial anatomic information on heart valves, real-time three-dimensional echocardiography (3DE) combined with color Doppler has the potential to overcome the limitations of flow quantification inherent to conventional 2D color Doppler methods. Recent studies validated the application of color Doppler 3DE (cD-3DE) for the quantification of regurgitation flow based on the vena contracta area (VCA) and the proximal isovelocity surface area (PISA) methods. Particularly the assessment of VCA by cD-3DE led to a change of paradigm by understanding of the VCA as being strongly asymmetric in the majority of patients and etiologies...

The mitral valve disease (MVD) in Lutembacher's syndrome has been infrequently analyzed from a pathological standpoint. In this study, we have attempted to elucidate the pathology of MVD in this interesting syndrome in 44 autopsied cases of combined non-primum atrial septal defect (ASD) and MVD collected over 16 years. The patients were divided into 3 groups: Group 1: non-primum ASD with clinically diagnosed mitral stenosis (MS)±regurgitation, Group 2: non-primum ASD with clinically diagnosed mitral regurgitation (MR) and, Group 3: non-primum ASD with no clinically evident MVD, but with mitral valve pathology diagnosed at autopsy...

Owing to its efficiency and cost effectiveness, auscultation using a stethoscope is the primary diagnosis method preferred by most medical examiners for cardiovascular disease. Phonocardiography (PCG) is the next level of auscultation and an effective analysis technique in cardiology. This paper presents a method to quantify Mitral Regurgitation (MR) using PCG. MR is one of the most common cardiovascular diseases associated with a defect in mitral valve. We analyzed the multifractal nature of heart sounds with murmur followed by classification and clustering using Hurst exponents...

Guillain-Barre syndrome (GBS)-associated achalasia is a very rare disease of uncertain cause. We report the case of a patient diagnosed with GBS-associated type I achalasia who was successfully treated with peroral endoscopic myotomy (POEM). A 30-year-old man who was diagnosed with GBS 3 mo before was referred to our department with dysphagia and meal-related regurgitation. The results of esophagography, endoscopy, and high-resolution manometry (HRM) revealed type I achalasia. POEM that utilized a submucosal tunneling technique was performed to treat the GBS-associated type I achalasia...

BACKGROUND: Patients with failed bioprostheses are an increasing population at high risk for redo surgery. Valve-in-valve transcatheter aortic valve implantation is a promising alternative but a limited number of first-generation devices have proven efficacy in all cases. METHODS: Patients with degenerated bioprostheses at high risk for redo surgery were included in the registry after being assigned to valve-in-valve intervention by a local heart team. Main basal and follow-up data (at 1 month and 6 months) of patients undergoing valve-in-valve transcatheter aortic valve implantation with the Lotus valve system (Boston Scientific, Natick, MA) in three high-volume Italian centers were entered in the registry...

BACKGROUND: Tricuspid regurgitation (TR) often accompanies ischemic mitral regurgitation and is generally assumed to be a secondary consequence of altered hemodynamics of the left-sided regurgitation. We hypothesized that it may also be a direct consequence of right-sided ischemic disease. Therefore, our objectives were to (1) characterize the nature of this TR and (2) describe its time course after mitral valve surgery for ischemic mitral regurgitation, with or without concomitant tricuspid valve repair...

Standard aortic valve replacement for aortic regurgitation caused by Behçet's disease is frequently complicated by postoperative recurrent prosthetic valve detachment. To prevent this, we have developed a modified Bentall procedure, in which the valved conduit is proximally attached to the left ventricular outflow tract instead of to the fragile annulus, based on the fact that the left ventricular outflow tract myocardium is rarely involved in Behçet's disease. This modified Bentall procedure was performed in 5 Behçet's disease patients with prosthetic valve detachment after primary aortic valve replacement, and satisfactory results were achieved...

MitraClip (MC) is an alternative therapeutic option for patients with severe mitral regurgitation (MR) who are at high surgical risk. Most candidates for MC have severe heart failure (HF) with increased N-terminal pro-B-type natriuretic peptide (NT-pro BNP) levels. We sought to clarify the response of NT-pro BNP after MC and to identify the determinants of NT-pro BNP nonresponders. Among 136 consecutive patients successfully treated with MC, we excluded 20 patients due to low baseline NT-pro BNP levels and therefore examined 116 patients...
