2% (5/26), and barbiturates in 11.5% (3/26). General anesthesia was preferentially maintained using volatile agents, 61.5% (16/26), with sevoflurane being the most common volatile agent within this group, 81.2% (13/16). Intraoperative first-choice/first-line inotropic drug was epinephrine, 53.8% (14/26), followed by milrinone, 23.1% (6/26), and dobutamine 15.4% (4/26). Fast-track programs performing on-table extubation depending on the type of surgical procedure were established at 61.5% (16/26) of the centers. CONCLUSION This study highlights the diversity of clinical standards in pediatric cardiac anesthesia for congenital cardiac surgery in Germany.The present perspective is a synthesis of published investigations in the setting of subvalvular aortic aneurysms. We identified 75 investigations and reviewed the clinical presentation, diagnostic modalities used, surgical techniques employed, and their outcomes. Clinical presentation, radiographic findings, transthoracic and transesophageal echocardiography, electrocardiogram-gated computerized tomography, and magnetic resonance imaging provided the diagnostic information and were used to define the disease entity before surgery. In this article, we have attempted to address several issues concerning establishment of diagnosis, varied clinical presentation, and their management. We submit that an increased appreciation of this disease entity will contribute to improved surgical management.A 49-year-old female with congenitally corrected (or levo-) transposition of the great arteries complicated by nonischemic cardiomyopathy presented for worsening heart failure despite guideline-directed medical therapy and was found to be in cardiogenic shock. She successfully underwent ventricular assist device placement with a HeartMate III to her systemic right ventricle as a bridge to transplantation.OBJECTIVES We aimed to evaluate the utility of computed tomography angiography (CTA) for coronary compression (CC) prediction in patients with congenital heart disease undergoing balloon-expandable transcatheter pulmonary valve replacement (TPVR). BACKGROUND Coronary compression is a serious complication of TPVR, but the value of preprocedural CTAs to assess CC risk is largely unexplored. METHODS In all, 586 patients underwent TPVR between January 2009 and July 2018. Adults with a pre-TPVR CTA and children with a CTA performed less than one year prior to TPVR were included. Patients with poor CTA image quality or with aborted cases due to reasons other than CC were excluded. Sixty-six patients were finally included. Cardiac anatomy was assessed via multiplanar reconstruction of CTAs. RESULTS Coronary compression occurred in 9 (14%) of the 66 patients who underwent TPVR. Most CC cases (seven of nine) occurred in patients with conduits. Proximity of the right ventricular outflow tract (RVOT) landing zone to the coronary arteries and to the chest wall was a significant risk factor for compression (P less then .001 and P = .019, respectively). Compression risk increased significantly if patients had an RVOT to coronary artery distance of ≤3 mm (P less then .001) and an RVOT to chest wall distance of ≤8 mm (P = .026). Anomalous course of coronary arteries was another significant univariate risk factor (P = .003). CONCLUSIONS Right ventricular outflow tract landing zone distance of ≤3 mm to a coronary artery, landing zone distance of ≤8 mm to the chest wall, and anomalous coronary arteries are associated with increased CC risk. Electrocardiogram gating may not be necessary if coronary arteries are opacified on CTAs. Larger studies are needed to explore and confirm these coronary artery compression risk factors.BACKGROUND Pediatric patients with sternum left open after cardiac surgery experience a higher risk for sternal wound infection (SWI). These infections are costly for programs, payers, and patients and their families. Despite efforts by individual programs to reduce infections in patients undergoing delayed sternal closure (DSC), there are no established guidelines that address preventive procedures. The purpose of this study was to determine the practice of pediatric cardiac surgery programs to prevent infection in their DSC patients and if preventive measures were associated with less infections. METHODS A 33 question survey on institutional practices was sent to chief surgeons at pediatric cardiac surgery programs in the United States. RESULTS Twenty-eight (35%) surgical programs responded. The mean number of pediatric cardiac bypass operations performed by programs in 2016 was 227 (range 69-872). buy CC-4047 Data represented 6,484 patients less then 18 years of age who underwent cardiac surgery with 807 (12%) of those undergoing DSC. One hundred fifty-eight (2.4%) of all patients and 51 (6.3%) of the DSC patients developed a SWI. Patients with DSC who received preoperative baths were less likely to become infected (5.9% vs 15.8%; P = .015). Patients in programs with feeding protocols had fewer infections (5.7% vs 14.8%; P = .008). CONCLUSIONS The results of this survey of children's cardiac surgery programs describe their practices to reduce infection rates in DSC patients. A multicenter project on wound care and closure techniques that might impact this costly complication is needed.Acute kidney injury following orthotopic heart transplantation in pediatric recipients is often multifactorial, requiring balance of immune suppression, nephrotoxic medication exposure, nutrition, and fluid status. Therapeutic options are often limited by patient size and hemodynamic stability. We describe a four-month, 4.9-kg female bridged by mechanical circulatory support to transplant after failed stage 1 palliation secondary to recurrent aortic stenosis and severe ventricular dysfunction. Posttransplant, kidney injury was managed by transcatheter relief of central obstruction from an anastomotic stricture and continuous renal replacement therapy, allowing uninterrupted immune suppression, medication, and nutrition delivery until sufficient recovery of renal function.Fontan-associated protein-losing enteropathy is difficult to treat and associated with poor prognosis. Cardiac rehabilitation and exercise are thought to have beneficial effects for patients with Fontan circulation. We report the case of a young adult patient palliated to Fontan circulation, with a decade-long history of symptoms related to protein-losing enteropathy. At age 23 years, he appreciated an improvement in symptoms and laboratory values after cardiac rehabilitation and prescriptive exercise.BACKGROUND Improved survival of children with congenital heart disease (CHD) into adult life has led to further study of their quality of life (QoL) and its determinants. The QoL including the symptoms of anxiety and depression of adults with CHD was analyzed to determine the relationship, if any, between prior cardiac surgery and QoL. link2 METHODS Adults with CHD who were recruited from a single community-based cardiology practice completed self-reported questionnaires on their QoL, which included symptoms of anxiety and depression. Standard linear regression analysis was used to determine whether prior cardiac surgery predicted lower QoL scores. RESULTS One hundred forty-nine adult patients with CHD were sent QoL questionnaires. Completed questionnaires were received from 135 patients 71 (53%) males and 64 (47%) females, with a mean age of 26.3 years (standard deviation 7.8, min 17, max 49). Respondents were assigned to two groups those who had (n = 89, 66%) or had not (n = 46, 34%) previously undergone one or more cardiac surgical interventions. Results from standard linear regression analyses revealed no predictive relationship between history of previous cardiac surgery, whether one or more operations, and QoL. CONCLUSIONS Among adult patients with CHD who completed QoL questionnaires, we observed no association between a patient's history of prior cardiac surgery and self-reported QoL measures. This welcome and important finding may be a reflection of the good functional capacity of both groups (postsurgical and nonsurgical) irrespective of the original CHD diagnosis and need for surgical intervention.Spot blotch, caused by fungal pathogen Bipolaris sorokiniana Shoemaker, is one of the most frequent diseases affecting barley-growing regions worldwide. In this study, we reported the genome sequence of the highly virulent B. sorokiniana strain GN1 using the Illumina HiSeq 4000 platform. In total, 57 million 150-nucleotide paired-end clean reads were obtained and assembled into 96 scaffolds with an estimated genome size of 34.33 Mb. Furthermore, we identified genes that may be associated with strain-specific virulence and performed phylogenetic analysis of GN1 with five other Bipolaris spp. These results for GN1 will provide important information in understanding its molecular underpinning of pathogenicity and help identify novel sources of genetic resistance for improving disease resistance in barley.Fungal wilt and root rot diseases affecting tomato have become prevalent in China in recent years and have caused considerable damage. In 2016 to 2018, symptoms of putative wilt and root rot diseases were observed in several locations in tomato cultivars with resistance to Fusarium oxysporum f. sp. lycopersici races 1 and 2. The objective of this study was to identify the causative agents of wilt and root rot of tomato in China and provide a basis for disease prevention and resistance breeding programs. Based on DNA sequence analyses of the internal transcribed spacer (ITS) region, 91 isolates from the roots of tomato plants showing symptoms of wilt and root rot were identified, including F. oxysporum (64 isolates), Fusarium solani (11 isolates), Fusarium proliferatum (2 isolates), Fusarium graminearum (2 isolates), Fusarium equiseti (1 isolate), Pythium aphanidermatum (6 isolates), Ascomycota sp. (2 isolates), and Plectosphaerella cucumerina (3 isolates). F. oxysporum accounted for 70.33% of the isolates obtained. In this case, using PCR-based methods for differentiation of F. oxysporum, we identified several formae speciales and races of F. oxysporum 7 isolates were identified as F. oxysporum f. sp. lycopersici race 1, 2 isolates as F. oxysporum f. sp. lycopersici race 2, 35 isolates as F. oxysporum f. sp. lycopersici race 3, and 13 isolates as F. oxysporum f. sp. radicis-lycopersici. Pathogenicity tests revealed 55 isolates of tomato wilt and root rot pathogens to be virulent. This study demonstrated that F. oxysporum f. sp. link3 lycopersici race 3 was the most widespread and highly virulent race among these tomato pathogens in China, followed by F. oxysporum f. sp. radicis-lycopersici. Therefore, the development of resistant varieties of tomato against F. oxysporum f. sp. lycopersici race 3 and F. oxysporum f. sp. radicis-lycopersici would aid efforts to develop effective disease management strategies.Wheat stripe (yellow) rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a serious fungal disease worldwide, especially in the Huang-Huai-Hai region, a main wheat production area in China. Gene postulation, molecular testing, and pedigree analysis were conducted to determine the presence of stripe rust resistance genes to 15 Pst races in 66 selected commercial wheat cultivars released from 2000 to 2016. In addition, races CYR32, CYR33, and CYR34 were used to evaluate resistance to Pst at the adult-plant stage of wheat in the field. Four Yr genes (Yr9, Yr10, Yr26, and Yr32) were postulated in 24 wheat cultivars either singly or in combination. Thirty-six cultivars might contain unknown Yr genes, whereas no identified Yr gene was postulated in six cultivars. Yr9 was detected at a frequency of 28.8%, and no cultivars carried Yr5, Yr15, or Yr18. Ten cultivars (15.2%) exhibited adult-plant resistance in the field tests with three predominant races. Three cultivars (Langyan 43, Xinong 889, and Yunfeng 139) had all-stage resistance.
