title: [Critical hypertrophic obstructive cardiomyopathy patient with improved hemodynamics following mitral valve replacement: report of a case].
abstract: A 75-year-old man with dyspnea was admitted to our hospital in critical condition. Catheterization showed normal coronary arteries and good left ventricular function. Transesophageal echocardiography showed left ventricular hypertrophy and severe mitral regurgitation. We decided to perform mitral valve replacement because the patient was in critical condition and it was necessary to complete the operation smoothly. During the operation, we could see the dilated mitral valve annulus and hypertrophic mitral valve, which was restricted. The patient's hemodynamics showed improvement after mitral valve replacement with a mechanical prosthesis, and he was discharged on postoperative day 21. In conclusion, mitral valve replacement is a beneficial method for the treatment of patients with critical hypertrophic obstructive cardiomyopathy.
