Postmyocardial infarction ventricular septal defect is an increasingly rare mechanical complication of acute myocardial infarction. We present a case of acute myocardial infarction from right coronary artery occlusion that developed hypotension and systolic murmur 12 hours after successful percutaneous coronary intervention. Although preoperative imaging suggested a large ventricular septal defect and a pseudoaneurysm, intraoperative findings concluded a serpiginous dissection of the ventricular septum. The imaging technicalities are discussed.
Congenitally corrected transposition of the great arteries poses a challenge in the adult cardiology practice because of its diverse clinical presentation. It is crucial that internists, cardiologists, and sonographers maintain a high degree of suspicion after meticulous physical examination for the early recognition of ccTGA, and thus avoid associated morbidities. Through some case examples, we provide clues to the key diagnostic features that could help them to be vigilant in making a diagnosis.
Counterintuitive respiratory-related fluctuations in LVOT gradients were observed in this case series of 20 HCM patients. These findings challenge traditional haemodynamic teaching and demonstrate the contribution of LV transmural pressure to LVOT obstruction in certain HCM patients.
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.
