Diagnosis of tricuspid regurgitation by contrast echocardiography.
Sixty-two subjects underwent M-mode and two-dimensional echocardiographic studies that included imaging of the inferior vena cava (IVC) during upper extremity contrast injections. Group 1 consisted of 10 patients with clinical tricuspid regurgitation (TR). Group 2 consisted of 40 patients without definite clinical signs of TR but with conditions known to be commonly associated with TR (e.g., mi...
متن کامل3D echocardiography for traumatic tricuspid regurgitation.
T H E T R I C U S P I D V A L V E ( T V ) I S A C O M P L E X S T R U C T U R E . Unlike mitral and aortic valves, simultaneous visualization of the 3 TV leaflets cannot be achieved with 2-dimensional echocardiography (2DE) due to valve orientation with reference to the imaging planes. No 2D echo plane is parallel to the tricuspid valve. Therefore, there is no short-axis view for the tricuspid ...
متن کاملDiagnosis of lead-induced tricuspid regurgitation
Introduction Clinically important lead-induced tricuspid regurgitation (LITR) is an uncommon complication following cardiac device implantation. Surgical removal and replacement of a lead may improve heart failure caused by LITR. Percutaneous lead extraction and reimplantation may also improve or correct LITR. However, whether severe tricuspid regurgitation (TR) is caused by a lead is often unc...
متن کاملQuantitative assessment of tricuspid regurgitation using pulsed Doppler echocardiography.
Tricuspid valve regurgitation was assessed quantitatively by measuring blood flow velocity in the vena cava using a pulsed Doppler velocimeter. A non-invasive index of regurgitation was obtained by calculating the ratio between the maximum amplitudes of the systolic and diastolic components of the velocity curves. The index was compared with the angiographic grading of regurgitation in 70 patie...
متن کاملSevere tricuspid regurgitation 14 years after diagnosis of "transient neonatal tricuspid regurgitation".
A 14 year old girl presented with severe tricuspid regurgitation after she was diagnosed with "transient tricuspid regurgitation of the newborn". In the neonatal period she had presented with severe tricuspid regurgitation without an obvious underlying anatomical cause. This spontaneously regressed during the first months of life. She was dismissed from follow up at the age of 5 years after com...
