OBJECTIVE To analyse patient data to elucidate the apparent association between an abnormal karyotype and tricuspid regurgitation found during fetal echocardiography at early gestations. SETTING Tertiary referral centre for fetal medicine and cardiology. METHODS Fetuses between 11 and 14 weeks' gestation were selected for detailed echocardiography. Referral reasons were increased nuchal tra...

as pre-existing abnormalities, such as tricuspid valve annular dilatation or pulmonary hypertension, may be present. The mechanism of tricuspid regugirtation plays an important role in the choice of treatment. If tricuspid regurgitation caused by the endocardial lead is managed by surgery, medical treatment is needed for other reasons. Defining the precise anatomical relationship between the tr...

Severe and permanent tricuspid regurgitation induced by pacemaker leads is rarely reported in the literature. The mechanism of pacemaker-induced tricuspid regurgitation has been identified, but its management has not been well established. Furthermore, debate still exists regarding the proper surgical approach. We present the case of a patient with severe tricuspid regurgitation induced by a pa...

Pressure-volume relationships in the right atrium were examined before and after the creation of acute experimental tricuspid regurgitation in pigs. A 1.3 kHz multielectrode impedance catheter with a measuring current of 4 mA was used to determine instantaneous right atrial pressure and relative blood volume; right atrial dimension was assessed simultaneously with ultrasonic crystals attached t...

The management of recurrent tricuspid regurgitation after tricuspid valve repair in patients with Ebstein anomaly is difficult, and tricuspid valve replacement is most commonly performed in such patients. We report two cases of recurrent tricuspid regurgitation in patients with Ebstein anomaly that were successfully re-repaired using the cone technique. The cone repair technique is a useful sur...

OBJECTIVES We report a series of patients with severe tricuspid valve regurgitation due to a permanent pacemaker (PPM) or implantable cardioverter-defibrillator (ICD) lead. BACKGROUND Severe tricuspid regurgitation caused by a PPM or ICD lead is an under-recognized but treatable etiology of severe right heart failure. METHODS We reviewed the records of 41 patients who underwent tricuspid va...

Heart valve injuries due to non-penetrating blunt thoracic trauma are rare. Isolated tricuspid incompetence due to detachment of a leaflet from the annulus after blunt trauma is uncommon. Young patients may tolerate chronic tricuspid regurgitation (TR), and can be undiagnosed for years until the right ventricular failure occurs. We report the case of a young adult male who sustained blunt chest...

The most common etiology of tricuspid stenosis is rheumatic, and in most cases it is associated with valvular regurgitation. Interestingly, there have been reports of tricuspid stenosis without associated valvular regurgitation, mostly related to pacemaker leads. Percutaneous tricuspid valvuloplasty may be a therapeutic alternative to surgery in cases of pure tricuspid stenosis without other co...

Pressure-volume relationships in the right atrium were examined before and after the creation of acute exerimental tricuspid regurgitation in pigs. A 1.3 kHz multielectrode impedance catheter with a measuring current of 4 mA was used to determine instantaneous right atrial pressure and relative blood volume; right atrial dimension was assessed simultaneously with ultrasonic crystals attached to...
