Key result
Surgical mitral valve replacement combined with prolonged mechanical circulatory support and antiarrhythmic therapy successfully treated a patient with post-infarction papillary muscle rupture and sustained ventricular tachycardia.
Case Report (n=1)
No
Prolonged mechanical circulatory support combined with antiarrhythmic therapy can be effective for managing drug-resistant ventricular tachycardia and respiratory failure following surgical repair of post-infarction papillary muscle rupture.
May inform management of refractory post-MI VT after papillary muscle repair; leaves open need for prospective evaluation before broader adoption.

Kitabayashi et al. (2008) conducted a case report in Papillary muscle rupture after myocardial infarction with sustained ventricular tachycardia (n=1). Mitral valve replacement, mechanical circulatory support (PCPS/IABP), and antiarrhythmic therapy was evaluated on Survival and clinical recovery. Surgical mitral valve replacement combined with prolonged mechanical circulatory support and antiarrhythmic therapy successfully treated a patient with post-infarction papillary muscle rupture and sustained ventricular tachycardia.
