Viability, Remodeling, and CABG
F ollowing myocardial infarction, left ventricular (LV) remodeling is characterized by increased LV end-diastolic and end-systolic volumes (ESV) and decreased LV ejection fraction (EF) (1). This process is driven by elongation of infarcted zones and changes within the unaffected myocardium, including myocyte hypertrophy and interstitial collagen deposition. With medical therapy, revascularizati...
متن کاملAssessment of Myocardial Viability and Protection during Cabg
Dynamic imaging with stress echocardiography has been evaluated as a method to distinguish viable from nonviable myocardium. It is well recognized that regional left ventricular dysfunction is often reversible and exists in territories of viable myocardium. l-4 Indeed, it is widely recognized that reversible segmental wall-motion abnormalities caused by transient myocardial ischemia are the hal...
متن کاملMyocardial Viability and Remodeling: Does Size Matter?
I schemic heart disease with resultant left ventricular (LV) dysfunction is the major underlying cause of heart failure and carries significant morbidity and mortality. Therapeutic endeavors to improve the prognosis of these patients have evolved over the years and include a multifaceted approach aimed at alleviating symptoms and improving ventricular function, and reducing reinfarction and sud...
متن کاملLeft heart chambers reverse remodeling after combined CABG and mitral repair
Results The mean effective ejection fraction increased from 18 ± 6% to 39 ± 13% (p << 0.05) at the follow-up. Left ventricular end-systolic volume index decreased from 44 ± 24 ml/m2 to 39 ± 26 ml/m2 (p = 0.002). Significant left ventricular reverse remodeling (≥ 15% reduction of LVESVI) was observed in 55 % of all survivors. Recurrent IMR was detected in only 2.8% (2/71) of the evaluated patien...
متن کاملEffect of isolated cabg on mild-to-moderate ischemic mitral regurgitation and cardiac remodeling
Results At follow-up 56 % of all survivors showed improvement in IMR grade, 32 % presented with the unchanged valve function and in only 12 % IMR grade was more severe than preoperative. Preoperative effective ejection fraction increased from 26 ± 8% to 32 ± 14% (p = 0.002) at the follow-up. Left ventricular end-systolic volume index (LVESVI) decreased from 35 ± 16 ml/m2 to 30 ± 14 ml/m2 (p = 0...
