Cases of uncorrected adult tetralogy of Fallot are rare and mostly manifest secondary to complications. A 30-year-old man presented with progressive breathlessness and severe chest discomfort. Echocardiography revealed tetralogy of Fallot with a left ventricular apical clot and DeBakey type I dissection of the aorta. The patient underwent successful surgical correction. The combination of preoperative complications in the setting of uncorrected tetralogy of Fallot, such as a left ventricular clot and DeBakey type I dissection of the aorta, is very rare.
Transcatheter heart valve retrograde migration after transcatheter aortic valve implantation is unusual. It can occur during the implantation of the aortic transcatheter heart valve, i.e., intra-procedural, or in the first few days following the intervention. Transcatheter valve embolisation and migration soon after deployment typically results from the implantation of a prothesis that was undersized for the annulus, an unreasonably low implantation, or the expulsion of the device following deployment by an excessive ventricular contraction. The presented case highlights the importance of the timing of the complication that has taken place, in this case, intra-procedural, which has become relevant to the research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
