Cardiac Tumours

The need to histologically exclude the cystic atrioventricular node tumour

“…Some cases have implanted pacemakers. 2,3,4 Rarely, CAVNT may be seen on transoesophageal echocardiogram, cardiac magnetic resonance imaging or computed tomography. 2,3,5…”

“…3 The CAVNT ranges in size from 3 to 30 mm and is rarely evident or easily overlooked on gross examination. 2,3 The CAVNT is considered to be endodermal heterotopia, resulting from endodermal tissues misplaced during embryonic development (cardiac looping), perhaps reflecting an altered gene function responsible for embryological tissue migration. 2 The CAVNT is debatably not a neoplasm in the classical sense, although this area remains controversial.…”

“…1 Characteristically found in cases of sudden death, the mode of death is likely dysrhythmic, due to interference of normal cardiac conduction. 2 Antemortem clues may include heart block, syncope and palpitations. Some cases have implanted pacemakers.…”

“…Some cases have implanted pacemakers. 2,3,4 Rarely, CAVNT may be seen on transoesophageal echocardiogram, cardiac magnetic resonance imaging or computed tomography. 2,3,5 The CAVNT is a lesion sited at the AVN, at the base of the atrial septum or apex of the triangle of Koch.…”
