A Case of Pulmonary Arteriovenous Shunt Diagnosed by Microbubble Test via a Swan-Ganz Catheter.

When encountering severe hypoxemia that does not respond to oxygen supplementation, it is essential to consider underlying right-to-left shunting. Among various diagnostic approaches, the microbubble test via transthoracic echocardiography (TTE) is a simple, noninvasive method for detecting pulmonary arteriovenous shunts, particularly in hepatopulmonary syndrome (HPS). Although microbubbles are usually administered peripherally, using a Swan-Ganz (SG) catheter to inject microbubbles directly into the pulmonary artery may provide even more definitive diagnostic information.

Background: Acute illness states with increased metabolic demand can precipitate severe thiamine deficiency if physiologic needs exceed endogenous stores and supplementation. Patients with preexisting risk factors such as parenteral nutrition (PN) dependence, eating disorders, gastrointestinal disorders, or surgeries are especially vulnerable.
Case Summary: A 9-year-old girl with short bowel syndrome receiving long-term PN, including standard thiamine supplementation, presented with refractory shock following aspiration.
Vicious cycle of vitamin B insufficiency and heart failure in cardiology outpatients.
J Clin Biochem Nutr

Research Support Center, Shizuoka General Hospital, 4-27-1 Kita-Ando, Aoi, Shizuoka 420-8527, Japan.
Heart failure is a major manifestation of vitamin B deficiency; beriberi. We have previously reported that even vitamin B insufficiency, milder than deficiency, is a risk for heart failure in the institutionalized elderly. Then in this cross-sectional study, sixty-eight cardiology outpatients were evaluated for their whole blood vitamin B and plasma brain natriuretic peptide (BNP) concentrations, a sensitive marker of heart failure, as well as their dietary intake.
