Iatrogenic type-A aortic dissection due to transcatheter aortic valve implantation

Spontaneous Resolution of Extensive Iatrogenic Type A Aortic Dissection After Transcatheter Aortic Valve Replacement

“… 3 , 4 Endovascular therapy had a remarkable outcome in several cases, but its application was limited to type B AD. 5 Few patients had recovered with medical treatment; as in our case, 6 , 7 they were in hemodynamically stable condition and had no pericardial effusion or branch vessel compromise. However, we did not find any cases presenting the natural course of extensive TAAD immediately after TAVR with complete serial imaging data, and the mechanism of spontaneous resolution remains unclear.…”

Validation of a novel staging classification system based on the extent of cardiac damage among Chinese patients after transcatheter aortic valve replacement: A single‐center retrospective study

“…Taking periprocedural complications as an example, aortic dissection and hemodynamic collapse are highly associated with unfavorable outcomes after TAVR; however, both metrics are hard to predict via regular pre-TAVR assessments. 23,24 Additional research is warranted to consider these rare but fatal complications in terms of risk stratification.…”

“…Although traditional and novel stratification tools are well developed within the field of cardiology, some specific risk factors have not been included in these tools for a variety of reasons. Taking periprocedural complications as an example, aortic dissection and hemodynamic collapse are highly associated with unfavorable outcomes after TAVR; however, both metrics are hard to predict via regular pre‐TAVR assessments 23,24 . Additional research is warranted to consider these rare but fatal complications in terms of risk stratification.…”

Rescue Percutaneous Stenting for Cerebral Malperfusion With Acute Aortic Dissection Following TAVR

“…The incidence of iatrogenic AAD after TAVR ranges from 0.2% to 2% ( 1 , 2 ). Although there are a few case reports describing the conservative management of AAD resulting from TAVR ( 3 ), acute organ malperfusion caused by an iatrogenic AAD requires timely surgical or catheter intervention. In general, the standard treatment of AAD with brain malperfusion is surgical aortic reconstruction; however, AAD causing disturbance in consciousness is associated with increased mortality after surgical repair ( 4 ).…”
