Because an improvement of receptor sensitivity after carotid surgery is related to a long-lasting reduction of blood pressure levels and variability, baroreceptor function may be considered an indirect indicator for the later postoperative course.
Objectives: Isolated left ventricular abnormal trabeculation (ILVAT) is defined as >3 coarse trabeculations of the left ventricular wall, apically to the papillary muscles, in hearts without congenital malformations. The aims of the study were to assess by echocardiography the prevalence of ILVAT, look for cardiac findings in ILVAT and find out if ILVAT is associated with neuromuscular disorders. Design and Results: In the course of 3 years, ILVAT was found in 15/17, 648 patients (0.08%). Twelve patients had heart failure, all had ECG abnormalities. All patients had neuromuscular disorders. A definite diagnosis could be established in 10 patients (metabolic myopathy, n = 9; Becker’s muscular dystrophy, n = 1). The remaining 5 patients refused further neurological investigations. Conclusions: ILVAT is a rare disorder associated with ECG abnormalities, heart failure and neuromuscular disorders, which is a reason why both cardiologists and neurologists should be involved.
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.
