Mitral hemi-arcade: an unusual modification of a rare anomaly.

Published: November 2012

Congenital anomalies of the mitral valve are rare. A mitral arcade is defined as a fibrous continuity between the papillary muscles and the anterior mitral leaflet creating a hammock like suspension. We present images of a mitral anomaly that consists of a direct attachment of the anterolateral papillary muscle to the anterior mitral leaflet, which we have labeled as a "hemi-arcade." We discuss the surgical findings and review the available literature regarding a mitral "arcade".

Case Report: We report the case of a 63-year-old patient who underwent aortic valve replacement with a biological valve for a bicuspid aortic stenosis, and LIMA-IVA single-bypass surgery. Two weeks later, he presented with Enterococcus faecillis bacteremia, attributed to left pyelonephritis and successfully treated with Amoxicillin. Two months after his surgery, he had a new bacteremia due to Enterococcus faecalis and we discovered a pseudo-aneurysm of the mitro-aortic trigone.

Background: Minimally invasive cardiac surgery for mitral regurgitation is challenging in patients with narrow chests due to limited thoracic space. The butterfly technique can prevent systolic anterior motion in patients with degenerative mitral regurgitation and redundant posterior leaflets, but it is difficult to perform via minimally invasive cardiac surgery. Few reports have described mitral valve repair using the butterfly technique or in a narrow chest.

Norepinephrine (NE) released from locus coeruleus (LC) noradrenergic (NAergic) neurons plays a pivotal role in the regulation of olfactory behaviors. However, the precise circuits and receptor mechanisms underlying this function are not well understood. Here, in DBH-Cre mice model, we show that LC NAergic neurons project directly to both anterior piriform cortex (aPC) and the olfactory bulb (OB).

Background: Granulomatosis with polyangiitis (GPA) is an autoimmune multisystem disorder characterized by small vessel vasculitis with granulomatous inflammation. In this report, we describe a unique case of GPA who presented with complete heart block (CHB) and developed complications due to intracranial large vessel involvement.

Case Summary: A 47-year-old gentleman presented with CHB with a background history of arthralgia and blood-tinged nasal discharge.
