Virtual TEE: Using spectral Doppler to evaluate the pulmonary veins
Identify the pulmonary veins (PV) in the mid-esophageal views. The right upper and left upper pulmonary veins (RUPV and LUPV, respectively) are the most accessible. The following four two-dimensional TEE views can be used: Left Atrial Appendage View; Modified Left Pulmonary Vein View; Modified Bicaval View; Modified Right Pulmonary Vein View
Anatomy of Pulmonary Veins by Real-Time 3D TEE:
We describe a systematic step-by-step approach of acquisition modality of each PV by RT3DTEE, their normal appearance, comparison with equivalent anatomic specimens and examples of its use during catheter-based PV ablation.
TEE FOR PULMONARY VEINS AND ITS IMPORTANCE - Cardiac …
TEE to locate Left Pulmonary Veins - The left upper pulmonary vein (LUPV) lies above or posterior to the left atrial appendage (LAA). Laminar Color Doppler flow above coumadin ridge identifies LUPV .
Pulmonary venous flow by doppler echocardiography: revisited 12 years ...
Using TEE, the site of stenosis in all four pulmonary veins could be observed two-dimensionally and the severity estimated by the increased PVF velocities . This complication should be acutely treated by balloon dilation (64) .
Anatomy of Pulmonary Veins by Real-Time 3D TEE - ScienceDirect
2012年4月1日 · The electrical isolation of pulmonary veins (PVs) has become a highly effective treatment option for symptomatic, drug-resistant atrial fibrillation (AF). RT3DTEE may potentially represent a novel monitoring modality for anatomy-driven PVs isolation. However, a standardized RT3DTEE protocol for imaging acquisition and processing of PVs is lacking.
Virtual TEE: Using spectral Doppler to evaluate the pulmonary valve
Identify the pulmonary valve (PV) in the mid-esophageal views. The following two-dimensional TEE views can be used: Upper-Esophageal Aortic Arch Short Axis View; Modified Transgastric Basal View
3D Real-Time TEE During Pulmonary Vein Isolation in Atrial Fibrillation
We sought to prospectively evaluate the ability of RT3DTEE to visualize the pulmonary vein (PV) ostia and to compare RT3DTEE and the electroanatomic mapping system (EAMS) for localizing the ablation catheter tip during pulmonary vein isolation (PVI).
Evaluation of pulmonary vein stenosis by transesophageal ...
1995年11月1日 · Pulmonary vein stenosis was diagnosed by transesophageal echocardiography in five patients who underwent the study for different clinical indications. Stenosis was encountered in the right upper pulmonary vein in two patients, the right lower pulmonary vein in two patients, and at the confluence of the left pulmonary veins in one patient.
TEE images of normal connection of pulmonary veins, flow and …
Download scientific diagram | TEE images of normal connection of pulmonary veins, flow and pulsed Doppler pattern. Top left panel: Right superior pulmonary vein (RSPV), right middle...
Detection of pulmonary vein stenosis by transesophageal ...
Transesophageal echocardiography was able to detect most pulmonary veins with good sensitivity and specificity in comparison to MDCT. Pulmonary veins may be visualized more frequently by MDCT; however, TEE provides additional data about the functional significance of a pulmonary vein stenosis.
