Broviac Catheter-Related Aortic Valve Infective Endocarditis Complicated With Massive Aortic Regurgitation Requiring Emergency Surgery: A Case Report.

Broviac catheter is a type of central venous catheter (CVC) used for long-term parenteral nutrition in specific patients, e.g., diagnosed with intestinal failure as short bowel syndrome (SBS). The way of the catheter insertion is conceived to minimalize the risk of infections. However, CVC-related blood stream infections (CVC-BSIs), including infective endocarditis (IE), remain most important complications associated with Broviac catheter. stands out as a prevalent pathogen. The increasing number of CVCs results in an increased incidence of healthcare-associated IE. Complete parenteral treatment is an independent risk that increases the likelihood of IE. Treatment of IE is mainly based on antibiotic therapy, but in certain cases, surgical treatment is needed. A 71-year-old female with SBS who had been receiving total parenteral nutrition through the Broviac catheter for several months was admitted in a serious condition with significant weakness, increasing shortness of breath, deteriorating cough, fever, low blood pressure, and heart palpitations. Echocardiography revealed severe aortic valve IE with a large, longitudinal, highly mobile vegetation (up to 40 mm) and massive aortic regurgitation with pulmonary edema. Fast pathogen detection in the patients' blood () was obtained using PCR-based multiplex test. Due to life-threatening conditions, emergency surgery with aortic valve replacement was performed. Consistent rehabilitation resulted in good condition achievement. Follow-up echocardiography showed normal function of the aortic valve bioprosthesis. The use of CVC, including Broviac catheter, is associated with an increased risk of infections, including IE. Treatment-resistant severe HF complicating IE requires emergency surgery.
