BACKGROUND: Twenty percent of patients born with congenital heart disease present with right ventricular outflow tract abnormalities. These patients require multiple surgical procedures in their lifetime. Transcatheter pulmonary valve replacement (TPVR) has become a viable alternative to conventional pulmonary valve and right ventricular outflow tract surgery in pediatric and adult populations. In this retrospective review, we analyze the perioperative management of adult patients who underwent TPVR in our center...

Several proteins such as membrane-associated ectonucleotidases: ecto-5'-nucleotidase (E5NT/CD73) and ectonucleoside triphosphate diphosphohydrolase 1 (ENTPD1/CD39), and intracellular heme oxygenase-1 (HO-1) may contribute to protection from inflammation-related diseases such as calcific aortic valve stenosis (CAS). Accurate quantification of these proteins could contribute to better understanding of the disease mechanisms and identification of biomarkers. This report presents development and validation of quantification method for E5NT/CD73, ENTPD1/CD39 and HO-1...

Endocardial cells are specialized endothelial cells that form the innermost layer of the heart wall. By virtue of genetic lineage-tracing technology, many of the unexpected roles of endocardium during murine heart development, diseases, and regeneration have been identified recently. In addition to heart valves developed from the well-known endothelial to mesenchymal transition, recent fate-mapping studies using mouse models reveal that multiple cardiac cell lineages are also originated from the endocardium...

Background -Aortic valve stenosis (AS) is the most common indication for cardiac valve surgery; untreated AS is linked to high mortality. The aetiological background of AS is unknown. Previous human studies were typically based on case-control studies. Biomarkers identified in prospective studies could lead to novel mechanistic insights. Methods -Within a large population survey with blood samples obtained at baseline, 334 patients were identified that later underwent surgery for AS (median age (interquartile range) 59...

Percutaneous intervention for mitral valve (MV) disease has been established as an alternative to open surgical MV repair in patients with prohibitive surgical risk. Multiple percutaneous approaches have been described and are in various stages of development. Edge-to-edge leaflet plication with the MitraClip (Abbott, Menlo Park, CA) is currently the only Food and Drug Administration-approved device specifically for primary or degenerative lesions. Use of the edge-to-edge clip for secondary mitral regurgitation is currently under investigation and may result in expanded indications...

OBJECTIVE: The number of surgeries for valvular heart disease performed in Japan has greatly increased over the past decade, and surgical aortic valve replacements (SAVR) constitute the vast majority of aortic valve replacement procedures. Although transcatheter aortic valve implantation (TAVI) was recently introduced, studies have yet to compare the clinical outcomes between TAVI and SAVR in the Japanese healthcare setting. This study aimed to compare in-hospital outcomes between TAVI and SAVR using a multicenter administrative database...

Background: The selection of a future breeding dog is a complicated task, in which disease characteristics and different traits have to be combined and weighed against one another. Truncation selection, that is the exclusion of affected animals, may be very inefficient when selecting on a large number of traits, and may result in a reduction of the genetic diversity in a population or breed. Selection could be facilitated by the use of a selection index that combines multiple traits or breeding values into one score...

Transcatheter mitral valve repair (TMVR) is an emerging treatment modality that has been reserved for high-risk patients with multiple co-morbidities. We hypothesize that TMVR is a safe and effective procedure for patients with moderate to severe mitral regurgitation who are not surgical candidates. The National Inpatient Sample (2012 to 2014) using the International Classification of Diseases, 9th Revision, Clinical Modification procedure codes 35.97 for TMVR and 35.12 for surgical mitral valve repair (SMVR) were used...

Carcinoid heart disease is a rare form of heart disease due to secretion of vasoactive compounds, including serotonin, from gastrointestinal tumors. This E-challenge examines the case of a patient with advanced carcinoid heart disease who presented to the operating room (OR) for a tricuspid valve replacement. Once the patient was in the OR, intraoperative transesophageal echocardiography was used to discover a patent foramen ovale and involvement of all 4 valves with regurgitant lesions. The patient underwent tricuspid valve replacement, pulmonic valve replacement, right ventricular outflow tract reconstruction, and patent foramen closure in the OR and experienced subsequent fulminant right heart failure...

Mucopolysaccharidosis type I (MPS I) is a lysosomal storage disorder with multisystemic features, including heart enlargement, heart valve dysfunction, and aortic stiffness and dilatation. Previous studies have shown that MPS I mice overexpress cathepsin B (CtsB) in multiple tissues, including those from the cardiovascular system. Here, we hypothesized that inhibition of CtsB could ameliorate cardiac function parameters, as well as aorta and valve abnormalities found in MPS I. First, we found that total elastase activity in an MPS I aorta is elevated...

Bicuspid aortic valve is the most common congenital cardiac defect in adults, and symptom typically develops in adulthood. In the majority of cases, bicuspid aortic valve disease progress with ages and surgical aortic valve replacement is performed with excellent operative outcomes. However, with the relatively slow progression of disease, surgical aortic valve replacement is required in elderly patients but the surgical risk often deemed extremely high due to old age and multiple comorbidities. Transcatheter aortic valve replacement (TAVR) has evolved from a novel technology to an established therapy for intermediate- and high-risk patients with symptomatic severe aortic valve stenosis (AS)...

BACKGROUND: Mitral regurgitation is a heterogeneous disease. Determining which patients derive optimal outcomes from transcatheter edge-to-edge mitral valve repair (TMVR) remains challenging. We sought to determine whether baseline mitral valve anatomic characteristics are predictive of left atrial pressure (LAP) changes during TMVR with MitraClip. METHODS AND RESULTS: Consecutive patients with severe mitral regurgitation undergoing TMVR (n=112) underwent continuous intraprocedural LAP monitoring and retrospective echocardiographic analysis for specific mitral anatomic characteristics...

BACKGROUND: Tranexamic acid (TXA) is a common antifibrinolytic agent used to minimize bleeding in cardiac surgery. Up to 50% cardiac surgical patients have chronic renal dysfunction (CRD). Optimal dosing of TXA in CRD remains poorly investigated. This is important as TXA is renally eliminated with accumulation in CRD. High TXA doses are associated with postoperative seizures. This study measures plasma TXA concentrations in CRD cardiac surgical patients for pharmacokinetic modeling and dose adjustment recommendations...

Coarctation of the aorta (CoA) is a relatively common congenital heart anomaly, and bicuspid aortic valve (BAV) is a common congenital heart disease that coexists with CoA. In larger children and adults with CoA, transcatheter intervention has gained acceptance, but for surgical high-risk patients with aortic stenosis, the use of transcatheter aortic valve implantation (TAVI) has been established. Recently, although favorable data have been reported for TAVI when treating BAV, simultaneous transcatheter intervention for CoA and BAV will prove to be a challenge because of the unique anatomy involved requires multiple procedural steps and also has problems of site access...

Mitral regurgitation (MR) is the most frequent Valvular Heart Disease (VHD) and is an important cause of heart failure. MR can be caused by primary valve abnormality (Degenerative MR/Primary MR) or it can be secondary to cardiomyopathy (Functional MR/Secondary MR). Medical management alleviates symptoms but does not alter the progression of the disease. Current guidelines recommend surgery for moderate-to-severe (Grade > 3) MR in patients with symptoms or evidence of left ventricular dysfunction. Despite current practice guidelines, the majority of patients with severe MR do not undergo surgery...

OBJECTIVES: An increasing number of octogenarians are referred to undergo mitral valve surgery for degenerative disease, and percutaneous approaches are being increasingly used in this subgroup of patients. We sought to determine the survival and its predictors after Mitral valve Surgery in Octogenarians (MiSO) in a multicenter UK study of high-volume specialized centers. METHODS: Pooled data from 3 centers were collected retrospectively. To identify the predictors of short-term composite outcome of 30 days mortality, acute kidney injury, and cerebrovascular accident, a multivariable logistic regression model was developed...

We report a patient presented with recurrent pericardial effusion caused by drug-induced systemic lupus Erythematosus (SLE) following mitral valve repair. The surgery was complicated by hemiparesis and convulsion in early postoperative period. The patient had been received carbamazepine for a paroxysmal seizure that occurred following mitral valve repair. The post operative computed tomography showed embolic stroke and its sequel (seizure) that treated with carbamazepine. In the 3rd month of follow-up, however, hemiparesis recovered by physiotherapy but carbamazepine was not discontinued as by request of neurologist...
