Ebstein's anomaly in combination with tetralogy of Fallot (TOF) is rare. We report a male infant with these combined anomalies who presented with severe cyanosis, heart failure, and respiratory distress after birth. Biventricular repair was successfully performed with 1-stage correction of his ventricular septal defect (VSD), right ventricular outflow tract (RVOT) obstruction, and tricuspid regurgitation. The downward displaced tricuspid valve was also restored to the normal annulus position. The infant recovered well...

Objective The non-fluoroscopic navigation (NFN) is known to reduce the fluoroscopic time during catheter ablation of various arrhythmias. We aimed to study the impact of NFN over several procedural parameters during radiofrequency (RF) catheter ablation of the cavo-tricuspid isthmus (CTI) in patients with CTI-dependent atrial flutter. Methods Data about 124 consecutive patients with CTI ablation performed were retrospectively collected. The patients were divided into two groups: (1) ablation with two diagnostic catheters deployed in the coronary sinus and around the tricuspid annulus (NFN-, n = 62); (2) ablation with the same two catheters plus NFN system using cutaneous patches (NFN+, n = 62)...

Myxoma is the most common tumor in the heart. A typical myxoma is relatively straightforward to diagnose. However, certain cardiac myxomas have rare features. We report three extremely rare cases of cardiac myxoma. One case involved a myxoma that originated from the annulus of the tricuspid after valvuloplasty, one case involved myxomas associated with left atrial thrombus and severe mitral stenosis, and the third case involved myxoma combined with severe calcification. All three cases were diagnosed by echocardiography and pathology...

BACKGROUND: Surgical repair of functional tricuspid regurgitation (FTR) is an increasingly common practice, but annuloplasty suture dehiscence remains a significant problem. Quantitative and mechanistic understanding of annular suture holding strength can support more effective techniques for tricuspid valve device anchoring. METHODS: Suture holding strength of ovine tricuspid annuli (n = 15) was quantified ex vivo by pullout testing at 12 positions around their circumference...

OBJECTIVES: In the surgical treatment of pulmonary atresia with intact ventricular septum, the size of the tricuspid valve annulus (as measured by z-scores) has emerged as a significant factor in deciding which repair to perform. Various tricuspid valve annulus z-scores are reported as "cutoffs" for successful biventricular repair. We aimed to determine whether the use of different z-score data sets contributed to the gross variation in "cutoffs" for successful biventricular repair reported in the literature...

OBJECTIVES: A prosthetic system to repair secondary tricuspid valve regurgitation was developed. The conceptual engineering of the current device is based on 3D segmental remodelling of the tricuspid valve annulus in lieu of reductive annuloplasty. This study was designed to investigate the operational safety of the current prosthetic system with regard to the anatomical integrity of the right coronary artery (RCA) in fresh cadaveric human hearts. METHODS: During the study period, from January to April 2016, the current prosthetic system was implanted on the tricuspid valve annulus in fresh cadaveric human hearts that met the study's inclusion criteria...

BACKGROUND: Septic cardiomyopathy is a common finding in septic shock patients. The accepted definition of septic cardiomyopathy is often based on the left ventricular ejection fraction (LVEF). The aim of this study was to determine whether the left ventricular longitudinal systolic function was more sensitive than the LVEF in heart function appraisal of septic shock patients. METHODS: This was a case-control study conducted at a 40-bed Intensive Care Unit (ICU) of Peking Union Medical College Hospital...

Ventricular tachycardias (VT) in the healthy heart, also known as idiopathic VTs, often have a focal origin. Triggered activity due to delayed after-depolarization is the most likely mechanism of focal VTs. Localization of the site of origin of focal VTs is based on activation mapping with or without combination with pace mapping. The characteristic anatomic site of origin of idiopathic VTs is the right and left outflow tract. Other sites include the tricuspid and mitral annulus, the papillary muscles, and Purkinje fibers...

BACKGROUND: Echocardiographic right ventricular (RV) function assessment is difficult and still a gray area despite rapid advancement of imaging modalities. The aim of this study is to assess the role of echocardiographic RV outflow tract (RVOT) function in the form of RVOT fractional shortening (RVOT FS) and RVOT systolic excursion (RVOT SE) for the assessment of RV function. METHODS: We studied ninety individuals divided equally into two groups. The control group included 45 normal healthy individuals and age-matched patient group included 45 patients with RV dysfunction which was defined by tricuspid annular plane systolic excursion (TAPSE) <16 mm and RV fractional area change (RV FAC) ≤35%...

BACKGROUND: Neonates with severe forms of Ebstein anomaly present a surgical challenge, and the Starnes operation as single ventricle palliation is highly advocated. Cone reconstruction for tricuspid valvuloplasty (TVP) has become a widely accepted technique, although very few cases of TVP have been reported in neonates. This report describes a surgical strategy for neonatal Ebstein anomaly, with an aim toward biventricular repair. METHODS: Since 2007, 7 neonates or young infants with severe Ebstein anomalies have received TVP at the National Taiwan University Hospital, Taipei, Taiwan...

Tricuspid regurgitation (TR) is commonly encountered in the management of patients with a variety of cardiovascular diseases. Primary TR is the result of structural abnormalities of the valve or chordal attachments whereas functional TR results from alterations in right ventricular (RV) or right atrial (RA) size, shape or function. The vast majority of TR cases seen in practice are functional in nature and usually results from left-sided heart disease (e.g., mitral valve disease, left ventricular (LV) systolic dysfunction) and/or pulmonary vascular disease, though it also manifests in the presence of isolated chronic atrial fibrillation (AF)...

BACKGROUND: Even though the tricuspid annulus (TA) is anatomically and functionally related to right atrioventricular dependence and tricuspid annular plane systolic excursion (TAPSE) is a well-known measure of right ventricular (RV) systolic function, there is paucity of data regarding the potential impact that right atrial (RA) size and function have on TAPSE. Hence, we sought to determine whether RA volumetric and longitudinal measures affect TAPSE in patients with chronic pulmonary hypertension (cPH)...

A healthy 18-year-old girl was referred to our hospital for further evaluations of cardiac angiosarcoma. Transthoracic echocardiography showed an immobile 4.6 cm×3.7 cm cardiac mass. The mass was occupying right atrial chamber and partially, invading into annulus of tricuspid valve on transesophageal echocardiography. At surgery, the mass was seen to be protruding from right atrial appendage and adhering to right side of pericardium. The histological findings were consistent with cardiac angiosarcoma and immunological staining was positive for CD34 and CD31...
