Abstract

Background: Aortic stenosis severity assessment plays a central role in determining appropriate clinical management. Variability between imaging modalities may influence diagnostic accuracy and therapeutic decisions. This study aims to compare transthoracic echocardiography and transesophageal echocardiography in grading aortic stenosis among patients undergoing aortic valve replacement. Methods: This prospective observational study included 50 patients scheduled for aortic valve replacement, each undergoing both transthoracic echocardiography and intraoperative pre-cardiopulmonary bypass transesophageal echocardiography. Aortic valve area (AVA), mean pressure gradient, peak jet velocity, and dimensionless index were measured using standard echocardiographic techniques. Paired comparisons between the two modalities were performed using a paired t-test with α = 0.05 and a 95% confidence interval (CI). Result: Transthoracic echocardiography yielded a mean aortic valve area of 0.584 ± 0.08 cm², whereas transesophageal echocardiography measured 0.623 ± 0.07 cm², demonstrating a significant difference (p = 0.020). Transesophageal echocardiography reported a lower mean pressure gradient (39.08 ± 6.15 mmHg) and peak jet velocity (3.71 ± 0.42 m/s) compared with transthoracic echocardiography (49.14 ± 7.85 mmHg and 4.23 ± 0.53 m/s, respectively), with both parameters showing statistically significant differences (p < 0.001). No significant difference in the dimensionless index was observed between the two modalities (p = 0.250). Conclusion: Transesophageal echocardiography presents higher AVA measurements but lower pressure gradients and peak velocity values than transthoracic echocardiography, potentially altering aortic stenosis severity grading. Dimensionless index values remain consistent between modalities. Standardized evaluation protocols are required to guide the selection of the most appropriate imaging modality for accurate assessment of aortic stenosis.

Abstract

Medical educational institutes have begun offering online classes in preparation for the COVID-19 pandemic. The course work of MBBS phase-I was completed by an online mode of teaching, but the students' satisfaction feedback is still needed to improve online teaching. After receiving approval from the institutional ethical committee, the feedback from 250 Phase-I MBBS students was collected. The student participation was voluntary and 212 students respond about online-classes feedback on the google form.  The data were collected and analyzed in Excel and SPSS software. p-value <.05 was considered significant. The majority of students (90 percent of males and 94 percent of females) use their smartphones to attend online classes, and the majority of students experience network problems often or sometimes; only 6% of students were rarely affected by network issues. Only a quarter of students were satisfied with the online mode of teaching, half were neutral and the remaining quarter were unsatisfied. The internet access issue (p-value=0.101) as well as satisfaction level (p-value =0.985) were not affected by the student residence (urban/rural). The majority of students (62%) prefer face-to-face learning in the classroom, whereas 1/4th prefer watching a live playback video of online lectures and only 1/10th choose live-online sessions. Only one-fourth of students were satisfied with online classes and the majority of students suffer from the quality of internet services. Students prefer face-to-face interactive classroom learning. Students acknowledge the benefits of online teaching with the need for further improvement.
