“…Indirect data pertaining to: (a) the decreased survival span once symptoms of overt HF present [9], (b) the exclusion of patients with severe RHF from cardiac surgery or the unfavorable outcomes in the presence of RHF [42,49], (c) the difference in survival between patients with and without cardiac involvement [8], (d) the improvements in postoperative survival over the last decades [31,35], and (e) the use of novel imaging techniques, such echocardiographic LV and RV strain [50,51], which has been accompanied by incremental diagnostic and prognostic value over traditionally recommended conventional echocardiographic indices, has created a trend toward the application of heart surgery upon echocardiographic detection of CHD, prior to the appearance of symptoms of RHF [52]. However, the recent, large study by Connolly et al [36] failed to demonstrate an independent association between preoperative: (a) presence of advanced HF (NYHA III or IV), (b) signs of RHF (ascites, leg edema), (c) echocardiographic findings of RV dysfunction, and (d) time from carcinoid diagnosis and operation, and cumulative postoperative survival. On the other hand, anasarca edema and the need for intravenous diuretics prior to cardiac surgery independently predicted perioperative mortality.…”
