Extracellular matrix for reconstruction of cardiac structures after tumour resections


Sündermann, Simon H; Müggler, Oliver; Caliskan, Etem; Reser, Diana; Manka, Robert; Holubec, Tomas; Czerny, Martin; Falk, Volkmar (2015). Extracellular matrix for reconstruction of cardiac structures after tumour resections. Interactive Cardiovascular and Thoracic Surgery, 20(1):10-14.

Abstract

OBJECTIVES: To describe the use of a new extracellular matrix patch as a means for atrial reconstruction in patients with cardiac tumours.
METHODS: A new extracellular matrix patch was used to reconstruct atrial and neighbouring structures after tumour resections. In 1 case, it was used to reconstruct the atrial septum and the left atrial roof after excision of a huge myxoma. In a second case, it was used to reconstruct the right atrium, including the superior vena cava after excision of a primary cardiac sarcoma. In a third case, it was used to reconstruct both atria, the right-sided pulmonary venous confluence and the roof of the coronary sinus after excision of a metastasis of malignant melanoma.
RESULTS: In all cases, reconstruction was successful and facilitated because of the flexible and thin character of the extracellular matrix, which also seemed to be advantageous with regards to haemostasis.
CONCLUSIONS: Extracellular matrix patches are a potential alternative for pericardial patches for complex reconstructions of atrial structures because of their pliable characteristics and consecutively reduced need for haemostatic stitches.
