StudyScenarioL.M. is a 60 year old woman who is admitted to your telemetry unit in a major medical center after being successfully resuscitated by medics from a cardiac arrest due to ventricular fibrillation (v-fib). L.M., a divorced homemaker, had her sudden death experience in the small rural community where she lives and was transported to your facility for evaluation and treatment after she was stabilized. At the time of the arrest, her potassium level was 2.8 mmol/L and magnesium level was 1.3 mg/dl. As you continue to review her medical history, you learn that she had rheumatic fever as a childand over the years has developed severe rheumatic heart disease with mitral and aorticvalve involvement and dilated cardiomyopathy. Four years ago she had a commissurotomy for mitral valve stenosis (MVS). She also has probable aortic valve stenosis (AVS). During the past year she has experienced increasing problems with chest pain etc. why would someone like L.M. be given Coumadin? what is a mitral valve commissurotomy and how is it carried out? Reviewing the above health history, what factors do you think contribute to her current symptoms of chest pain, SOB, dyspnea on exertion, cough, and fatigue? Explain your rationale for each. what factors in the above health history may have precipitated L.M’s cardiac arrest?
