Cardiac tumor is a very rare disease in clinical practice. Among primary cardiac malignant tumors, about 95% are sarcomas, which can originate from any part of the heart without gender difference, including angiosarcoma, undifferentiated sarcoma, malignant fibrous histiocytoma, and leiomyosarcoma. Since the tumor occurs in the heart, it is easy to induce critical illness such as heart failure and the overall prognosis is poor. Professor Tian Jianhui treated cardiac malignant tumor complicated with heart failure from the perspective of "the Greater Yang Meridian and Lesser Yin Meridian Infection", combined with modern biochemical indicators and western medicine treatment strategies, timely adjusted traditional Chinese medicine prescriptions, and provided clinical ideas for the integration of traditional Chinese and western medicine in the treatment of rare malignant tumor complicated with emergency.In this case, the patient was admitted to the hospital due to recurrence of right ventricular malignant tumor more than 8 months after resection, more than 1 month after resection, and chest tightness and dyspnea for 1 day. Combined with the patient's symptoms, signs and laboratory indicators, the patient was diagnosed with cardiac malignant tumor complicated with heart failure. The TCM diagnosis was accumulated disease (deficiency of heart Yang, deficiency of qi and blood stasis). After comprehensive treatment with traditional Chinese and western medicine, the patient's vital signs were stable. Combined with the latest genetic test results of the patient, combined with trametinib integrated traditional Chinese and western medicine anti-tumor treatment, the patient has no obvious discomfort during follow-up.,Chief complaint,　Recurrence of right ventricular malignant tumor more than 8 months after resection, more than 1 month, chest tightness and dyspnea for 1 day.,TCM diagnosis,　heart Yang deficiency, qi deficiency and blood stasis syndrome,Western medicine diagnosis,　cardiac malignant tumor; heart failure; tricuspid insufficiency; pulmonary arterial hypertension; cardiac function grade Ⅲ; incomplete right bundle branch block; diarrhea; hyponatremia,Curative effect outcome,　the patient's cardiac function was significantly improved, without palpitation, chest tightness, abdominal distension, limb swelling, sleeplessness, and bladder and stool regulation.
