Background: As ultrasound offers students an opportunity to study anatomy, physiology and pathophysiology actively, we used hand-held ultrasound (HHU) devices to augment current teaching of cardiac murmurs and pathology. Methods: Three types of teaching sessions (of different duration) were explored: 1) compulsory teaching on cardiac murmurs (n=40); 2) extra-curricular teaching of cardiac murmurs (n=8); 3) extra-curricular ultrasound course (n=6). We assessed students' ability to identify valvular lesions on auscultation, and anatomy and pathology on echocardiography, and sought qualitative feedback. Results: Using echocardiography to teach murmurs improved murmur recognition by auscultation alone from 23% pre-test to 93% post-test (p=0.017). Students were able to identify major cardiac anatomical landmarks on echo images (57% vs 98% ( p=0.027) in the voluntary teaching session lasting 90 minutes, and 40% vs 82% ( p=0.027) after the 3 week cardiac ultrasound course. The mean accuracy for diagnosing cardiac pathology on a printed image alone after the 3 week ultrasound course was 71%. Students unanimously found the sessions useful and engaging, and reported they would like further teaching about using ultrasound. Conclusion: Medical students found the sessions engaging, enjoyed this novel way of teaching and would like further teaching using ultrasound. Using hand-held ultrasound scanners to augment the teaching of cardiac murmurs to medical students is feasible and effective.
