    Background and Objectives: The role of coronary artery bypass grafting (CABG) on postoperative left ventricular (LV) function in patients with preoperatively preserved left ventricular ejection fraction (LVEF) is still being discussed and only a few studies address this question. This study aimed to assess LV function after CABG in patients with preoperatively preserved LVEF using left ventricular longitudinal strain assessed by 2D speckle tracking imaging (STI). Materials and Methods: Fifty-nine consecutive adult patients with coronary artery disease (CAD) referred for a first-time elective CABG surgery were enrolled in the final analysis of this prospective single-center clinical study. Transthoracic echocardiography (TTE), with conventional measures and STI measures, was performed within 1 week before CABG as well as 4 months after surgery. Patients were divided into groups based on their preoperative global longitudinal strain (GLS) value. Differences in systolic and diastolic parameters between groups were analyzed. Results: Preoperative GLS was reduced (GLS < -17%) in 39% of the patients. Parameters of systolic LV function were significantly reduced in this group of patients compared to the patient group with GLS% ≥ -17%. In both groups, 4 months after CABG there was a decline in LVEF but statistically significant only in the group with GLS% ≥ -17% (p = 0.035). In patients with reduced GLS, there was a statistically significant postoperative improvement (p = 0.004). In patients with preoperative normal GLS, there was not a significant change in any strain parameters after CABG. There was an improvement in diastolic function parameters measured by Tissue Doppler Imaging (TDI) in both groups. Conclusions: There is improvement in LV systolic and diastolic function after CABG in patients with preserved preoperative LVEF measured by STI and TDI. GLS might be more sensitive and effective than LVEF for monitoring improvements in myocardial function after CABG surgery in patients with preserved LVEF.

    Myxomas are cardiac neoplasms that are most commonly located in the left atrium, usually arising from the vicinity of the fossa ovalis. However, there have been cases, although very rarely, of valvular myxoma. A cardiac mass found incidentally on echocardiography can present a challenge in particular if asymptomatic or found in an unusual location. We present the case of a 58-year-old male with kidney disease treated with chronic dialysis, referred to the cardiology clinic because of an incidental finding of a mitral valvular mass on routine transthoracic echocardiography. Although this lesion was initially misdiagnosed as native valvular endocarditis with vegetation, a series of clinical and radiological investigations led to the preoperative diagnosis of possible papillary fibroelastoma or calcified thrombotic mass. Given the increased risk of embolization due to the mass being mobile and greater than 1 cm in size, the patient was referred to cardiac surgery. Excision of the mass without mitral valve replacement was performed. Histopathological findings of the mass revealed the existence of a cardiac myxoma. In such cases of a mitral valve mass, multimodality imaging should have of high priority to achieve an accurate diagnosis. Although a definitive diagnosis can only be established after surgical excision of the mass and histopathological confirmation, it is very important to consider a differential diagnosis of mitral valve myxoma in any patient with an unexplained mitral valve mass.
