Objectives The objective of this study was to review the long-term functional outcome of patients with Ebstein anomaly who had cardiac operation at our institution. Background Ebstein anomaly is a spectrum of tricuspid valvular and right ventricular dysplasia. Many patients will require operation in an attempt to improve quality of life. Methods From April 1, 1972, to January 1, 2006, 539 patients with Ebstein anomaly underwent 604 cardiac operations at the Mayo Clinic in Rochester, Minnesota. Patient records were reviewed, and all patients known to still be alive were mailed a medical questionnaire or contacted by telephone. Results At the initial operation at our institution, the mean age of the patients was 24 years (range 8 days to 79 years) and 53% were female patients. Survival at 5, 10, 15, and 20 years was 94%, 90%, 86%, and 76%, respectively. Survival free of late reoperation was 86%, 74%, 62%, and 46% at 5, 10, 15, and 20 years, respectively. Surveys were returned by 285 of 448 (64%) patients known to be alive at the time of this study. Two hundred thirty-seven (83%) patients were in New York Heart Association functional class I or II, and 34% were taking no cardiac medication. One hundred three patients (36%) reported an incident of atrial fibrillation or flutter, 5 patients (2%) reported having had endocarditis, and 1 patient ( Conclusions Patients have good long-term survival and functional outcomes after undergoing surgery for Ebstein anomaly. Atrial arrhythmias are common both before and after surgery. Many patients have had one or more successful pregnancies with a low-recurrence risk of congenital heart disease.

A search of peer-reviewed literature was conducted to identify reports that provide data on complications associated with pregnancy in women with structural congenital heart disease (CHD). This review describes the outcome of 2,491 pregnancies, including 377 miscarriages (15%) and 114 elective abortions (5%). Important cardiac complications were seen in 11% of the pregnancies. Obstetric complications do not appear to be more prevalent. In complex CHD, premature delivery rates are high, and more ...

Ebstein's malformation is a congenital anomaly of the tricuspid valve and right ventricle that is characterized by several features, each of which can exhibit a spectrum of malformation. The first is adherence of the leaflets of the tricuspid valve to the underlying myocardium, this representing failure of delamination during development. This feature involves the septal and inferior leaflets, but rarely the anterior leaflet ( Fig. 1 ). The second feature is anterior and apical rotational displa...

Abstract Ebstein's anomaly is a rare congenital heart defect that is characterized by a spectrum of anatomical abnormalities of the tricuspid valve that also involve the right atrium and right ventricle. The extant nomenclature for Ebstein's anomaly and our approach to the description of the severity of Ebstein's anomaly are reviewed with the objective of establishing a unified reporting system. Although there are common features in Ebstein's anomaly, there is a wide spectrum of pathology with a...

Abstract To determine the effects of definitive operation for Ebstein's anomaly on rest and exercise cardiorespiratory function, cycle exercise studies were performed on 38 patients with Ebstein's anomaly before definitive operation and on 11 patients after operation. An atrial septal defect was present in 29 of the 38 preoperative patients and in none of the postoperative patients. Seven of the postoperative patients had tricuspid valvuloplasty and four had valve replacement. Exercise tolerance...

: Ebstein's anomaly of the tricuspid valve is associated with right ventricular dilatation in approximately two-thirds of cases. Dilatation may be massive. It involves not only the right ventricular wall proximal to the tricuspid valve (atrialized ventricle) but also the right ventricle distal to the valve (funtional right ventricle), including the right ventricular infundibulum. For further definition of the pathogenesis of dilatation of the functional right ventricle (distal chamber), a morpho...

Background Although tricuspid valve surgery improves functional capacity in patients with Ebstein anomaly, it is not always associated with improvement in aerobic capacity. The purpose of this study was to identify the determinants of improved aerobic capacity after tricuspid valve surgery in adults with Ebstein anomaly with severe tricuspid regurgitation. Methods Retrospective study of patients with severe tricuspid regurgitation due to Ebstein anomaly that had tricuspid valve surgery at Mayo C...

Ebstein anomaly is a congenital malformation involving primarily the tricuspid valve, with failure of delamination from the underlying myocardium and right ventricular myopathy. Echocardiography is diagnostic in most patients and demonstrates apical displacement of the septal leaflet and variable tethering of leaflet tissue to the right ventricular myocardium. Operative intervention is considered for exertional symptoms, progressive right ventricular enlargement, or right ventricular dysfunction...
Purpose: Different surgical procedures were defined due to degree of Ebstein anomaly. In this study, we are reporting our surgical experience of adult patients with Ebstein anomaly. Methods: We analyzed the patients, who had operated with the diagnosis of Ebstein anomaly from March 2011 through February 2018, retrospectively. We evaluated patients in two groups: patients with cone type surgical repair were in Group 1 and patients with other surgical (Danielson, Carpentier) procedures were in Gro...
