Transthoracic and transesophageal echocardiography to diagnose ventricular septal rupture
BACKGROUND Rapid and accurate diagnosis of ventricular septal rupture (VSR) remains difficult, and the monitoring of hemodynamic deterioration is a prerequisite for the institution of adequate therapy. The timing of surgical repair is a matter of controversy. METHODS Transthoracic, transesophageal, color Doppler, and contrast echocardiography were evaluated in 17 patients with VSR in whom the diagnosis was confirmed by catheterization, surgery, or necropsy. RESULTS Routine transthoracic echocardiography visualized VSR in four out of 17 patients and, with additional views, in 12 out of 17 patients. Color Doppler echocardiography identified the rupture in 15 out of 16, and contrast echocardio…
Diagnosis of papillary muscle rupture after acute myocardial infarction by transthoracic and transesophageal echocardiography.
The sensitivity of transthoracic echocardiography to visualize the structural abnormality of papillary muscle rupture (PMR) after acute myocardial infarction can be anticipated to average about 50%; therefore, we evaluated five patients exhibiting the condition with both transthoracic and transesophageal echocardiography. The use of the two imaging techniques resulted in the fact that no instance of PMR was missed. Using transthoracic echocardiography in two patients and transesophageal echocardiography in four, the ruptured papillary muscle was visualized directly. Mitral insufficiency as an indirect sign was observed in all patients. In one patient the papillary muscle rupture developed i…
Remodeling der Aorta als rekonstruktive Maßnahme für Aneurysmen der Aorta aszendens
Eine weniger haufig gebrauchte Methode zur operativen Therapie des Aszendens-Aneurysmas ist die plastische Rekonstruktion im Sinne einer Reduktionsplastik mit anschliesender Ummantelung der nativen Aorta. Der Vorteil liegt in der vollstandigen Erhaltung der Endothelzellschicht der Aorta und der Beibehaltung der dynamischen Funktion der Sinus Valsalvae.¶ Von 1987–1998 wurden 20 Patienten mit einem Aneurysma verum nach der o.g. Methode operiert. In 9 Fallen (Gruppe I – mittleres Patientenalter 72 Jahre; Spannweite 64–78 Jahre) beschrankte sich der Eingriff auf die plastische Rekonstruktion der Aorta und konsekutive Ummantelung. Bei 11 Patienten (Gruppe II – mittleres Patientenalter 45 Jahre; …
Quantification of mitral valve stenosis by three-dimensional transesophageal echocardiography
The aim of this study was the evaluation of the diagnostic potentials of transesophageal 3D- echocardiography in the determination of mitral valve stenosis. 54 patients were investigated by transthoracic and multiplane transesophageal echocardiography. In 41 patients cardiac catheterization was performed. 3D- echocardiographic data acquisition was performed by automatic transducer rotation at 2 degree increments over a span of 180 degrees. The transesophageal probe was linked to an ultrasound unit and to a 3D- workstation capable of ECG- and respiration gated data acquisition, postprocessing and 2D/3D image reconstruction. The mitral valve was visualized in sequential cross-sectional planes…
Coronary artery bypass grafting in adult coronary artery disease due to suspected Kawasaki disease in childhood
Development of coronary artery aneurysms is one typical complication of Kawasaki disease and can cause coronary artery disease even in early childhood. Information about course and outcome in adults is rare. Here, we present a 49-year-old man with serious three-vessel coronary artery disease and giant coronary artery aneurysms following suspected Kawasaki disease.
Value of echocardiography in patient follow-up after surgically corrected type A aortic dissection.
Background To identify patients (pts) at risk of late complications, follow-up after surgery for type A aortic dissection is essential. We assessed the value of echocardiography to monitor patients after surgery for type A aortic dissection. Methods 80 out of 108 pts operated between 1989 and 1999 for type A aortic dissection survived surgery. 62 pts with at least one TEE, CT or MRI examinations during follow-up were included in this study. All pts had transthoracic echocardiography (TTE), 53 transesophageal echocardiography (TEE), 51 had CT, and 39 had MRI. Results At the first follow-up, 12 of 48 pts with aortic valve sparing surgery presented with aortic insufficiency >I degrees detected…
