Direct echocardiographic changes in patients with supratentorial tumors have not been documented. The primary aim was to assess and compare the transthoracic echocardiography changes in patients with supratentorial tumors presenting with and without raised intracranial pressure for neurosurgery.<\/jats:p>\n<\/jats:sec>\n\nMethods: <\/jats:title>\nPatients were divided into two groups based on preoperative radiological and clinical evidence of midline shift of <6 mm without features of raised ICP (Group 1) or greater than 6mm with features of raised ICP (Group 2). Hemodynamic, echocardiographic, and optic nerve sheath diameter (ONSD) parameters were obtained during the preoperative period and 48 h after the surgery.<\/jats:p>\n<\/jats:sec>\n\nResults: <\/jats:title>\nNinety patients were assessed, 88 were included for analysis. Two were excluded based on a poor echocardiographic window (1) and change in the operative plan (1). Demographic variables were comparable. About 27% of the patients in Group 2 had ejection fraction <55% and 21.2% had diastolic dysfunction in Group 2 in the preoperative period. There was a decrease in the number of patients with a left ventricular (LV) function <55% from 27% before surgery to 19% in the postoperative period in group 2. About 5.8% patients with moderate LV dysfunction in the preoperative period had normal LV function postoperatively. We found a positive correlation between ONSD parameters and radiological findings of raised intracranial pressure.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nThe study demonstrated that in patients with supratentorial tumors with ICP, cardiac dysfunction might be present in the preoperative period.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_186_2023","type":"journal-article","created":{"date-parts":[[2023,5,5]],"date-time":"2023-05-05T07:43:07Z","timestamp":1683272587000},"page":"166","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A
