Zusammenfassung
Ziel: Untersuchung des Stellenwertes der MRT in der postoperativen Verlaufskontrolle bei
funktionell singulärem Herz im Vergleich zu Echokardiographie und Kardangiographie.
Material und Methoden: Untersucht wurden 31 Patienten (Alter 6 Monate bis 30 Jahre) mit funktionell singulärem
Ventrikel nach palliativer Operation. 5 Patienten hatten Blalock-Taussig-Anastomosen,
8 Glenn-Anastomosen, 18 Patienten cavopulmonale Shunts (6 eine klassische und 12 eine
modifizierte Fontan-Zirkulation). Die Ergebnisse wurden mit Daten aus der perkutanen
Echokardiographie (31/31) und der Kardangiographie (6/31) in Bezug auf postoperative
morphologische Veränderungen verglichen. Ergebnisse: Die bei allen Patienten durchgeführte Echokardiographie konnte jeweils bei 70 % der
Patienten den Tunnel, die Glenn-Anastomose und die zentralen Pulmonalarterien aufgrund
von Einschränkungen des Schallfensters nicht einsehen, während die MRT und Angiographie
(6 Patienten) die exakte Anatomie wiedergaben. Jeweils ein Patient hatte starke Auslöschungsartefakte
im Tunnel und der linken Pulmonalarterien, die eine Diagnostik mit der MRT verhinderten.
Schlussfolgerungen: Die MRT ist eine geeignete Methode in der postoperativen Situation bei funktionell
singulärem Ventrikel mit Vorteilen gegenüber der Echokardiographie. Die Kardangiographie
sollte nur bei unklaren Befunden in der MRT durchgeführt werden.
Abstract
Purpose: To determine the value of MRI in the postoperative evaluation of a singular ventricle
compared to echocardiography and cardiac catheterization. Materials and Methods: Thirty-one patients (range: 6 months to 30 years) with a functional single ventricle
following palliative corrective operations. Five patients had a Blalock-Taussig-Shunt,
8 patients a Glenn-Anastomosis and 18 a cavopulmonary shunt (6 with classic Fontan-Circulation,
12 with modified cavopulmonary anastomosis). The results in terms of postoperative
morphologic changes were compared to percutaneous echocardiography (31/31) and cardiac
catheterization (6/31). Results: Echocardiography, which was performed on all patients, could not visualize the entire
length of the tunnel, the Glenn-Anastomosis or the central pulmonary arteries in 70
% of the patients due to an inadequate acoustic window. MRI was able to show the entire
tunnel in 11/12 patients and the central pulmonary arteries in 30/31 patients. The
exact anatomy was seen in all 6 patients undergoing cardiac catheterization. Conclusion: MRI is useful in the postoperative evaluation of a functionally single ventricle.
It is superior to echocardiography. Cardiac catheterization should be reserved for
patients with inconclusive MRI findings.
