Vapotherm added that the Vapotherm Precision Flow Hi-VNI system is currently the only product in the QAV
category and the Precision Flow Hi-VNI system is a viable alternative to Non-invasive Positive Pressure Ventilation (NiPPV) for most patients.
Our patient had quadricuspid aortic valve (QAV) IE complicated by two aortocardiac fistulae involving the left atrium.
Echocardiography, especially TEE, is the preferred imaging technique for the detection of aortocardiac fistulae and QAV [4, 7].
Only a few cases of EI involving QAV have been reported .
Few QAV infective endocarditis cases have been reported.

Tambem foi desenvolvido e aplicado um Questionario de Avaliacao Visual (QAV) por meio do qual os operadores expressaram suas sensacoes sobre os sintomas oculares, visuais e gerais, bem como os sinais comportamentais e as atitudes que fazem para minimizar o desconforto visual.
A tabela 4 apresentou os valores medios da exigencia visual (EV) nos postos de trabalho das bicas, de selecao e de alimentacao da esteira, obtidos com a aplicacao do Questionario de Avaliacao Visual (QAV).
Further, while the association of a QAV with hypertrophic obstructive cardiomyopathy may be rare (1) it is nonetheless often associated with other congenital heart defects.
Therefore, anyone who is not so familiar with this rare congenital heart defect should keep in mind that the most prevalent hemodynamic abnormality associated with a QAV is aortic regurgitation, often leading to aortic valve repair or replacement (3).
Quadricuspid aortic valve (QAV) was first defined by Balington in 1862 (1).
In conclusion, QAV
is a rare congenital malformation that can be easily diagnosed by transthoracic and transesophageal echocardiography.
