Inverted left atrial appendage masquerading as a cardiac mass

Leong MC, Latiff HA, Hew CC, Mazlan SL, Osman H

Echocardiography, 2013 Feb;30(2):E33-5.

An inverted left atrial appendage is a rare phenomenon post cardiac surgery. The lesion presents as an additional mass in the left atrium, which would trigger unnecessary concerns and frequently, a battery of tests. The lesion can be easily diagnosed using echocardiography. We report a case of inverted left atrial appendage in a patient post repair of common arterial trunk. Echocardiographic pictures and features which help to identify this lesion as well as to differentiate it from other possible left atrial mass are described. This article aimed to improve the awareness of sonographers toward this rare but possible post operative lesion.

Intraoperative echocardiographic delineation of the high take-off coronary ostia during an extensive surgical repair of the bicuspid aortic valve and dilated sinotubular junction: a case report

PMID: 27716083

BACKGROUND: This study reports the efficacy of intraoperative transesophageal echocardiography (TEE) for evaluation of high take-off coronary ostia and proximal coronary arterial flows as an alternative to preoperative coronary angiography.
CASE PRESENTATION: In a 65-year old male undergoing the bicuspid aortic valve (BAV) repair and the extensive remodeling of dilated sinus and tubular junction, and preoperative coronary angiography were unsuccessfully completed due to an allergic reaction to the contrast medium. Intraoperative TEE by employing various 3-dimensional volume images of coronary ostia and Doppler tracings of the coronary arterial flows enabled a thorough pre-procedural evaluation of the high take-off coronary arteries and post-procedural evaluation by confirming the absence of any compromise in coronary arterial flow.
CONCLUSION: In the present case, intraoperative application of various TEE imaging modalities enabled comprehensive evaluation of high-taking off coronary artery, as an alternative to preoperative coronary angiography, in a patient undergoing an extensive aortic valve and aortic root repair procedure.

Fulltext Symptomatic anaemia 17 years after double valve replacement

Wong MH, Chee KH, Azman W

Singapore Med J, 2009 Oct;50(10):e362-4.
PMID: 19907876

A 40-year-old Malay woman presented with increasing lethargy, palpitation and shortness of breath, 17 years after a mitral and aortic valve replacement. A Starr-Edwards prosthetic valve replaced the mitral valve, and a Bjork-Shiley prosthetic valve replaced the aortic valve. Biochemical parameters demonstrated intravascular haemolysis, as evidenced by haemoglobin 7.8 g/dL, reticulocyte count 8.4%, lactate dehydrogenase 2,057 IU/L and low haptoglobulin levels (less than 6 mg/dL). Transoesophageal echocardiography revealed a paravalvular leakage over the mitral valve. The haemoglobin levels remained persistently low despite frequent blood transfusions. She successfully underwent a second mitral valve replacement. Her anaemia resolved subsequently.

An accessory mitral valve leaflet causing left ventricular outflow tract obstruction and associated with severe aortic incompetence

Tamin SS, Dillon J, Aizan K, Kadiman S, Latiff HA

Echocardiography, 2012 Feb;29(2):E34-8.
PMID: 22044509 DOI: 10.1111/j.1540-8175.2011.01543.x

This case report describes a 20-year-old woman with Turner's syndrome who presented with reduced effort tolerance limited by dyspnea. She had previously been on pediatric cardiology follow-up for congenital subvalvular aortic stenosis first diagnosed at age 7. Unfortunately she defaulted after two visits before any intervention could be done. Transthoracic echocardiography demonstrated severe aortic incompetence (AI) with a membrane-like structure in the left ventricular outflow tract (LVOT). The mean pressure gradient across the LVOT on continuous wave Doppler was 41 mmHg. The membranous interventricular septum appeared aneurysmal and it was observed that the "subaortic membrane" had a connection to the anterolateral papillary muscle via a strand of chordal tissue. Further images were captured using two-dimensional and three-dimensional transthoracic and transesophageal echocardiography (iE33, Philips Medical Systems, Andover, MA, USA). After a review of the literature it was concluded that this appeared to be an accessory mitral valve (AMV) leaflet causing LVOT obstruction associated with AI. AMV tissue is a rare congenital malformation causing LVOT obstruction. Because it is so unusual, it may not be immediately recognizable even in a high volume echocardiography laboratory. The clue which helped with the diagnosis was the strand of chordal tissue which connected the mass to the papillary muscle. This anomaly is often associated with LVOT obstruction.
