Why the study?
Does the angiographic sign of 'neovascularity' accurately detect left atrial thrombus in patients with mitral valve disease?
Does the angiographic sign of 'neovascularity' accurately detect left atrial thrombus in patients with mitral valve disease?
The angiographic sign of 'neovascularity' in the left atrial appendage falsely indicated the presence of left atrial thrombus in patients with mitral valve disease.
Answers are grounded in this paper and cite their sources.
Neovascularity on angiography warrants caution in diagnosing left atrial thrombus; leaves open its reliability pending larger validation studies.
"Neovascularity" in the region of the left atrial appendage was demonstrated by coronary arteriography preoperatively in five patients with mitral valve disease and was attributed to the presence of thrombus in the left atrium. Subsequently, they underwent surgery, but thorough inspection of the left atrium did not reveal thrombus in any of the five patients. The presence of neovascularity without apparent thrombosis or false detection may be a result of tissue reaction and organization in an effort to resorb the thrombus.
