Quadricuspid Aortic Valve: A Case Report of an Asymptomatic Middle-Aged Man.

A quadricuspid aortic valve (QAV) is a rare congenital anomaly characterized by the presence of four leaflets in the aortic valve. We are reporting a case of a 59-year-old male who presented to the emergency department with non-cardiac chest pain. The discovery of QAV during the evaluation highlights the importance of considering cardiac causes, even in cases where the presenting symptoms may not appear directly related to the heart.

Elevated N-terminal pro-brain natriuretic peptide in Mycobacterium tuberculosis pulmonary infection without myocardial dysfunction.

Increased levels of N-terminal pro-brain natriuretic peptide (NT pro- BNP) in infectious settings may not reflect myocardial depression. In addition to NT pro-BNP measurement, clinical assessment remains a valuable tool for diagnosis and prognosis of heart failure. A case of excessively increased NT pro-BNP level associated with Mycobacterium tuberculosis infection that was not indicative of myocardial dysfunction is described.
