Valve replacement is the standard surgical treatment of diseased valves that cannot be repaired. The main goal of replacement is to exchange the diseased valve with one that has the engineering and hemodynamics as close as possible to the disease free native valve. However due to mechanical and fluid dynamic constraints all prosthetic heart valves (PHVs) are smaller than normal and thus are inherently stenotic. This represents a challenge when it comes time to replace a valve. The correct valve with the correct and matching profile has to be selected before the procedure to avoid possible complications. It is well recognized that patients are also prone to patient-prosthesis mismatch at long term which could have consequences in the clinical outcomes (1). The evaluation of patient-prosthesis mismatch (PPM) has not been sufficiently emphasized in common practice. Failure to recognize this fact may lead to significant hemodynamic impairment and worsening of the clinical status over the time. Making efforts to identifying patients at risk may decrease the prevalence of PPM, the economic impact to our health system, the morbidity and mortality involved in these cases as well as creates efforts to standardized pre-operative protocols to minimized risk of PPM. We present a case of a 78 years old male patient who underwent aortic valve replacement due severe aortic stenosis, afterwards his clinical course got complicated with several admissions for shortness of breath and decompensated congestive heart failure (CHF).
