…MR). These complications result from transmural myocardial necrosis and subsequent tissue disruption. Infarct expansion and, in some cases, a dissecting haematoma may precede rupture. The…

…substantially higher rupture risk; one guideline summary describes approximately a four fold greater risk. This difference informs the use of sex specific surveillance and repair…

…aortic dissection. Symptom onset in PAU may indicate lesion expansion and involvement of the adventitia, requiring urgent imaging because of the risk of rupture. Type…

…or both. The clinical consequences of extracellular volume expansion include elevated cardiac filling pressures, pulmonary congestion, systemic venous hypertension, and peripheral interstitial edema. These abnormalities…

…activation, aggregation, and fibrin formation. Within a stented segment, thrombus may also develop because of disturbed flow, residual dissection, inadequate stent expansion, incomplete apposition, or…

…the chamber and this leads to dilatation. The most common cause is valvular regurgitation (insufficiency). For example, aortic regurgitation causes the flow of blood from…

…resolution does not consistently permit identification of foamy macrophages. The occurrence of neoatherosclerosis helps explain why ISR and other stent related events may arise well…

…intraluminal mass and lesion haziness raise suspicion of thrombus, although haziness is not specific. Intravascular imaging can identify plaque disruption, thrombus and other structural features…
