Relation between the myocardium/left ventricular cavity-ratio and hemodynamic parameters in patients with dilated cardiomyopathy

Background: Open mitral operation in patients with massive left atrial thrombus still with high mortality due to intra-operative embolism. To prevent this mortality due to intra-operative embolism and to prevent this danger we practiced a surgical technique which includes careful handling of heart and obliteration of left ventricular cavity by bilateral compression.Method: We used this technique in patients of severe mitral stenosis with atrial thrombus during mitral valve replacement. Our technique was to obliterate the left ventricular cavity and thus keep the mitral cusps in a coapted position by placing gauge posterior to left ventricle and a compression over right ventricle by hand of an assistant with a piece of gauze. This obliteration prevented passage of fragments of left atrial thrombus towards collapsed left ventricle.Result: Before practicing this technique, 4 out 9 patients expired due to cerebral embolism . But after implementation of this technique in 17 patients no mortality or morbidity occurred.Conclusion: This technique of removal of left atrial thrombus during mitral valve replacement may be a safe procedure for preventing peroperative embolism.Bangladesh Heart Journal 2016; 31(1) : 26-28

Hemodynamic Improvement

Background Patients with terminal ischemic heart disease (IHD), severely depressed pump function with large LV dyskinesis with or without fibrosis do not benefit from revascularization alone; in time they are listed for transplantation. The long waiting list and lack of organ donors have imposed implementation of Direct Circular Repair (DCR) with total revascularization as an alternative. Methods DCR was performed on 17 patients with terminal IHD, after total revascularisation. The resected dyskinetic tissue was pathohistologicaly examined. Transesophageal ultrasound was performed pre- and early post-operatively and hemodynamic parameters measured invasively. Results Pathohistology showed that even in macroscopically viable myocardium where only dyskinesia without fibrosis persists, there are irreversible lesions on the ultrastructural level. Along with revascularization, with the application of DCR the LV spherical geometry was reconstructed with hemodynamic improvement. Conclusion Total revascularisation with DCR offers an alternative to transplantation in patients with wide anterior wall dyskinesia with or without fibrosis due to terminal IHD, the most frequent group listed for transplantation.
