Abstract: This is a case report of an uncommon form of subaortic stenosis caused by an abnormal accessory mitral leaflet simulating a left ventricular outflow tract tumor. A 5-year-old boy with a systolic heart murmur underwent cardiac catheterization which demonstrated a subaortic stenosis with a 90 mmHg peak systolic pressure gradient. Angiography showed a tumor-like structure in the left ventricular outflow tract. At operation this mass was found to be an abnormal bulky accessory mitral leaflet. Resection of this def… Show more

“…A rate of 3.8 L per day could achieve 80% of optimum yield during drought situations. The latter rate is similar to Malan and Jacobs (1994) rate of 27 L/mz, but is less than the 35 L per week recommendation of Furuta (1983).…”

“…This historic, but almost forgotten, article was the forerunner of the vast popular literature available today. Some cultural guides of more recent standing include publications by Vogts (1958Vogts ( , 1960Vogts ( , 1962Vogts ( , 1979Vogts ( , 1980, Watson and Parvin (1970), Furuta (1983), Harre (1988bHarre ( , 1995, McLennan (1993). The foundations for commercial protea cultivation in the Western Cape of South Africa were established during the 1940s to the 1970s by Frank C. Batchelor, who conducted the first breeding efforts, collected natural hybrids and established vegetatively propagated plants, set standards of quality, marketed cultivated proteas overseas, founded the forerunner of South African Protea Producers and Exporters Association (SAPPEX), and identified production research needs.…”

“…Previous studies report different features of the LVOT obstructing lesion, ranging from small nonobstructive masses of accessory mitral tissue 7 to tumor-like accessory tissue obstructing the LVOT. 8 In summary, we report the rare case of an asymptomatic patient with mild subaortic stenosis by an accessory mitral valve and with IVS aneurysm without shunt, highlighting the role of echocardiography in making the diagnosis.…”

“…Discrete subaortic stenosis was excluded because it does not present with chordal attachments and usually has the different appearance of a single, linear membrane in the LVOT. Previous studies report different features of the LVOT obstructing lesion, ranging from small nonobstructive masses of accessory mitral tissue 7 to tumor‐like accessory tissue obstructing the LVOT 8 …”

“…Other causes include severe hypovolemia or anemia and abnormalities of the mitral valve apparatus. LVOT obstruction due to mitral valve prolapse, 1 accessory tissue attached to the mitral apparatus 2 and elongated mitral chordae tendineae have been described 3 …”
