Detection of dissection of the aortic intima and media after angioplasty of coarctation of the aorta. An angiographic, computer tomographic, and echo…
1990
Balloon coarctation angioplasty (BCA) was performed in eight patients (five male and three female) who were 14-49 years old (mean, 27.3 years) with isolated discrete unoperated coarctation of the aorta (n = 7) and postoperative recoarctation (n = 1). BCA was successful in seven of eight patients, resulting in a decrease in the gradient (64 +/- 19 to 16 +/- 13 mm Hg, p less than 0.01), an increase in the diameter at the coarctation site (0.9 +/- 0.4 to 1.6 +/- 0.4 mm, p less than 0.01). Follow-up (6 months) has demonstrated continued gradient relief (6 +/- 9 mm Hg) and diameter increase (1.6 +/- 0.2 cm). Monitoring was performed by transesophageal echocardiography (TEE) during BCA, and befor…
Noonan-Syndrom mit der ungew�hnlichen Kombination von hypertropher Kardiomyopathie, konnatal bikuspider Aortenklappe und Aortenisthmusstenose mit hyp…
2004
Das Noonan-Syndrom ist gekennzeichnet durch kraniofaziale Dysmorphien wie Ptosis der Augenlider, Pterygium colli und durch einen tiefen nuchalen Haaransatz, durch Skelettveranderungen wie Kleinwuchs, Klinodaktylie, Kiel- und Trichterbrust und durch Organfehlbildungen, hauptsachlich Herzfehler, seltener einer Retentio testis und Nierenfehlbildungen. Das Noonan-Syndrom weist ein ahnliches Erscheinungsbild auf wie das Ullrich-Turner-Syndrom. Im Gegensatz zu dieser Chromosomenaberration sind aber Patienten beiderlei Geschlechts betroffen, sie weisen einen unauffalligen Chromosomensatz (46, XX bzw. 46, XY) auf und sind zeugungsfahig. Bei etwa der Halfte der Patienten mit Noonan-Syndrom bestehen …
Coarctation of the Aorta: Quantitative Analysis by Transesophageal Echocardiography
1987
Summary Transesophageal echocardiography and standard two-dimensional echocardiography were performed in 15 patients with suspected coarctation of the aorta. Aortic diameters and crosssectional areas were determined by means of TEE and compared with clinical findings and catheterization data. The isthmus of the aorta could be imaged in all patients using TEE, but in only seven patients using standard suprasternal echocardiography. Compared with controls, aortic diameters were narrowed in 9 of 15 patients, and cross-sectional areas were reduced in 13 of 15. There was a satisfactory correlation between TEE data and angiographic and hemodynamic data. TEE is a promising method of a diagnosing a…
