ABSTRACT
Left ventricular aneurysm (LVA) is a common complication of myocardial infarction. Traditional medical and surgical treatments are not effective or require high doctors' operational skills and patients' physical fitness. With the development of minimally invasive medical devices, it becomes possible for revivent TC system to treat LVA and reconstruct the left ventricle. This study introduces an existing product and its defect when used. From the perspective of clinical needs, we propose a new design of revivent TC system which realizes accurate force measurement and simplifies surgery.

A 76-year-old man with ischemic cardiomyopathy and functional severe mitral regurgitation, suffered from profound dyspnea. He displayed a very low ejection fraction (12%) and was diagnosed with cardiogenic shock. Initially, we inserted the IMPELLA 5.0 heart pump into the patient's left ventricle and began an optimal medical therapy regimen. Once hemodynamic stability was acquired, we performed left ventricular reconstruction, mitral valve replacement, and tricuspid annuloplasty. The patient was supported postoperatively with IMPELLA 5.0 and venoarterial extracorporeal membrane oxygenation. The patient was discharged on POD100. Overall, IMPELLA 5.0 may be a useful tool for perioperative support against cardiogenic shock.
ABSTRACT
Heart failure is a progressive disease. Although surgical interventions for heart failure are still being explored and improved,their use in children is limited. This paper introduced several kinds of heart surgery support treatment methods: left ventricular reconstruction, mitral valve plasty and coronary artery bypass surgery.
ABSTRACT
Objective To study the effects of enhanced external counterpulsation (EECP) on the diastolic heart failure in hypertensive patients.Methods 104 hypertensive patients with diastolic heart failure were randomly divided into treatment group and control group,52 patients were given 36 hours of treatment EECP.After 6 months,Doppler ultrasound recordings were obtained from all patients to determine the left ventrlcular diastolic function.Resuits Left ventricular diastolic function index and the left ventrich mass weight index (LVMI) wero impmved after treatment in both groups(P＜0.01),and EECP treated group was better than control group(P＜0.05).Conduslon For hypertensive patients with diastolic heart failure,EECP could not only improve heart diastolic function,but also reverse reconstruction of the left ventricuhr.
