The baroreflex system is involved in modulating several physiological functions of the cardiovascular system and can modulate cardiac output, blood pressure, and cardiac electrophysiology directly and indirectly. In addition, it is involved in regulating neurohormonal pathways involved in the cardiovascular function, such as the renin-angiotensin-aldosterone system and vasopressin release. Baroreflex dysfunction is characterized by sympathetic overactivation and parasympathetic withdrawal and is associated with several cardiovascular diseases, such as hypertension, heart failure, and coronary artery disease.

Methods: We analyzed data from the National Inpatient Sample of hospitalizations between January 2016 and December 2020 of patients aged 18 and over who underwent a HT or newly implanted LVAD. Quartile classification of the median household income of the patient's residential zip code was used to estimate SES.
A 79-year-old woman with a history of bioprosthetic aortic and mitral valve replacement with coronary artery bypass graft surgery presented with pulmonary edema 4 years after surgery. Transthoracic echocardiography and transesophageal echocardiography revealed an obstruction of the left ventricular outflow tract caused by the bioprosthetic mitral valve. We present this case, accompanied by a review of the literature.
