Summary: Dr. Derek Gibson lectures on the history and importance of the echocardiogram. 9 segments.
Title number: 18023
LSA ID: LSA/21180
Description: Segment 1 Dr Gibson introduces the subject and says that echocardiography has become indispensable in the assessment of patients with heart disease. An animated illustrative diagram is shown of a boundary wall between two different mediums. Gibson explains how the echocardiogram works across the boundary between the two mediums. An illustration of a dissected heart is shown and Gibson briefly explains its anatomy and where to place the transducer when taking the echocardiogram. An echocardiogram of the anterior cusp is seen, and he explains how to read it. Time start: 00:00:00:00 Time end: 00:06:32:11 Length: 00:06:32:11 Segment 2 Another echocardiogram is shown and Gibson explains how to read the normal mitra-diastolic closure. Another echocardiogram is seen from a patient with rheumatic mitral valve disease. Dr Gibson explains the reading. A further echocardiogram is seen from a patient with a disorganised and calcified mitral valve. Another is shown and Gibson explains how to measure the diastolic closure rate. Time start: 00:06:32:11 Time end: 00:10:38:00 Length: 00:04:05:14 Segment 3 A mitral valve echo from a patient with ruptured chordae tendineae is seen and Gibson analyses it. Another echocardiogram is seen showing another type of mitral valve abnormality. Another is seen, this time showing hypertrophic cardiomyopathy. The next echocardiogram is from a patient with severe aortic regurgitation. Gibson analyses all of these images. Time start: 00:10:38:00 Time end: 00:15:23:10 Length: 00:04:45:10 Segment 4 A further echocardiogram from a female patient who developed acute staphylococcal endocarditis of the aortic valve during pregnancy. A chest x-ray from a patient with mitral stenosis is seen, as well as an echocardiogram from the same patient. Gibson analyses all of these. Another echocardiogram is seen from a patient with mid-diastolic murmur and systemic embolism. An angiogram from a similar patient is shown. An echocardiogram from a patient with mitral stenosis is seen, and Gibson explains how to read it. Time start: 00:15:23:10 Time end: 00:20:08:17 Length: 00:04:45:15 Segment 6 Gibson says that a major application of echocardiography is studying left ventricular function. An early echocardiogram is seen. Another is seen from a normal subject, and Gibson explains how to read it. A computerised cineangiogram is seen, showing the outline of the opacified left ventricular cavity. A chart is seen, showing n-systole and n-diastole. Gibson explains how to read the chart and how to use the data. Time start: 00:24:54:00 Time end: 00:30:07:05 Length: 00:05:13:05. Segment 7 Gibson compares measurements from echocardiographs and angiographs in the same patients. A graph shows the results from 23 patients. A digitised cineangiogram of a patient with poor left ventricular function is seen. The echocardiogram from the same patient is then shown and Gibson analyses them. Another echocardiogram is seen, from a patient with ischaemic heart disease, followed by an angiogram of a patient with mitral and aortal regurgitation is seen. A diagram is seen looking at systole and diastole rates. Another graph is shown, and Gibson analyses all the charts to see if the data can be used practically. Time start: 00:30:07:05 Time end: 00:35:00:00 Length: 00:04:52:20. Segment 8 An echocardiogram of a patient with rheumatic mitral stenosis is seen a computer-generated graph shows the heart rate of the same patient. A graph showing the rate of wall movement in three patients after surgical replacement of a mitral valve is seen. Another echocardiogram of a patient with alternate ventricular ectopic beats is seen. Gibson explains that echocardiograms are useful in studying the septum. He also says they are useful in studying the left ventricular anatomy in association with the great arteries and the AV valves in congenital heart disease. An echocardiogram from such a patient is seen. Another is shown from a patient with an atrial septal defect. Time start: 00:35:00:00 Time end: 00:41:12:12 Length: 00:06:12:12. Segment 9 Gibson explains how to read the relationship between the mitral valve and the septum using an echocardiogram. Another is seen that shows the relationships between the great arteries and the septum to be abnormal, then another is shown from a patient with no septum. The final echocardiogram is from a patient with a double outlet right ventricle. The lecture ends with Gibson summarising that echocardiography has a great deal to contribute in the assessment of patients with heart disease. Time start: 00:41:12:12 Time end: 00:46:28:06 Length: 00:05:15:19

Further information: This video is one of more than 120 titles, originally broadcast on Channel 7 of the ILEA closed-circuit television network, given to Wellcome Trust from the University of London Audio-Visual Centre shortly after it closed in the late 1980s. Although some of these programmes might now seem rather out-dated, they probably represent the largest and most diversified body of medical video produced in any British university at this time, and give a comprehensive and fascinating view of the state of medical and surgical research and practice in the 1970s and 1980s, thus constituting a contemporary medical-historical archive of great interest. The lectures mostly take place in a small and intimate studio setting and are often face-to-face. The lecturers use a wide variety of resources to illustrate their points, including film clips, slides, graphs, animated diagrams, charts and tables as well as 3-dimensional models and display boards with movable pieces. Some of the lecturers are telegenic while some are clearly less comfortable about being recorded all are experts in their field and show great enthusiasm to share both the latest research and the historical context of their specialist areas.

Derek is a British intellect and a class of his own. His contribution to the cardiovascular and echocardiography science has been well recognised internationally from the US to the Far East. He is one of the rare British intellects whose work has been mostly based on selfless giving.
