We report an 18-year-old patient with severe mitral stenosis complicat
ed by right lower lobe pneumonia, sepsis, and shock, intractable Iow c
ardiac output led to an emergency percutaneous balloon mitral valvotom
y in a patient, resulting in immediately improved hemodynamic paramete
rs, We are unaware of another report of percutaneous balloon mitral va
lvotomy performed in a patient with sepsis and shock, This case suppor
ts previous isolated reports of the benefit from emergency percutaneou
s balloon mitral valvotomy in critical situations where thoracotomy is
not possible due to coexisting medical problems.
