A Modified Technique for Valve Regurgitation After Partial Atrioventricular Septal Defect Repair.

Given its complex pathologic anatomy, recurrent left atrioventricular valve regurgitation after partial atrioventricular septal defect repair remains a challenge for surgical correction. Here, we introduce a modified bridging technique by shortening the anteroposterior leaflet distance in selected patients with inadequate coaptation to compensate for the short leaflet height, specifically that of the anterior leaflet.

Transesophageal echocardiography for coronary sinus imaging in partially unroofed coronary sinus.

Background: Partially unroofed coronary sinus (PUCS) is a rare congenital cardiac anomaly and prone to be misdiagnosed. The purpose of this study was to explore the value of transesophageal echocardiography (TEE) in CS imaging for the detection of PUCS and to develop a special two-dimensional TEE-based en face view of CS.

Methods: Twenty adult patients with suspected PUCS, showing a dilated coronary sinus and an enlarged right heart on transthoracic echocardiography (TTE), underwent TEE examination.

Assessment of the morphology and mechanical function of the left atrial appendage by real-time three-dimensional transesophageal echocardiography.

Background: The left atrial appendage (LAA) is an important source of thrombus formation. We investigated the feasibility of the recently developed real-time three-dimensional transesophageal echocardiography (RT3D-TEE) method in assessment of the morphology and function of the LAA.

Methods: Ninety-six consecutive patients (58 males with a mean age of (43.

Experimental study of quantitative assessment of left ventricular mass with contrast enhanced real-time three-dimensional echocardiography.

Objectives: To evaluate the feasibility and accuracy of measurement of left ventricular mass with intravenous contrast enhanced real-time three-dimensional (RT3D) echocardiography in the experimental setting.

Methods: RT3D echocardiography was performed in 13 open-chest mongrel dogs before and after intravenous infusion of a perfluorocarbon contrast agent. Left ventricular myocardium volume was measured according to the apical four-plane method provided by TomTec 4D cardio-View RT1.
