    Notes: Cardiac arrhythmia surgery was initiated in 1968 with the first successful division of an accessory AV connection for the Wolff-Parkinson-White Syndrome. Subsequent surgical procedures included the left atrial isolation procedure and the right atrial isolation procedure for automatic atrial tachycardias, discrete cryosurgery of the AV node for AV nodal reentry tachycardia, the atrial transection procedure, corridor procedure and Maze procedure for atrial fibrillation, the right ventricular disconnection procedure for arrhythmogenic right ventricular tachycardia, the encircling endocardial ventriculotomy, subendocardial resection procedure, endocardial cryoablation, the Jatene procedure, and the Dor procedure for ischemic ventricular tachycardia. Because of monumental strides in the treatment of most refractory arrhythmias by endocardial catheter techniques during the past decade, the only remaining viable surgical procedures for cardiac arrhythmias are the Maze procedure for atrial fibrillation and the Dor procedure for ischemic ventricular tachycardia. Nevertheless, the 25–30 years of intense activity in the field of cardiac arrhythmia surgery provided the essential foundation for the development of these catheter techniques and represent one of the most exciting and productive eras in the history of medicine. In one short professional career, we have witnessed the birth of arrhythmia surgery, its adolescence as an “esoteric” specialty, its prime as an enlightening yet exhausting period, and finally its waning years as a source of knowledge and wisdom on which better methods of treatment have been founded. One could hardly ask for a more rewarding experience. (PACE 2004; 27:266–282)

    Notes: A. G. Hogg, although still not well known outside of India, has become in recent years the centre of increasing interest, particularly as studies of major missionary thinkers have demonstrated his importance to Protestant thought during the first half of this century.1 Hogg, who was Principal of the Madras Christian College from 1928 to 1938, first arrived in India from Scotland in 1903 as Professor of Philosophy at the College. During his first years in Madras, he contributed several articles to the Madras Christian College Magazine, the most significant being a series entitled ‘Karma and Redemption’ (1904–5), published in book form in 1909.2 In it, he outlined his fundamental missionary approach, which was based on his distinction between faith and faiths.

    Notes: The atria are anatomically complex three-dimensional (3-D) structures. Impulse propagation is dynamic and complex during both normal conduction and arrhythmia, Atrial activation has traditionally been represented on two-dimensional surface maps, which have inherent inaccuracies and are difficult to interpret. Interactive computerized 3-D display facilitates interpretation of complex atrial activation sequence data obtained from form-fitting multipoint electrodes. Accordingly, the purpose of this article is to describe the application of 3-D form-fitting electrode molds to the 3-D mapping and display system developed in this laboratory for the study of complex cardiac arrhythmias. Computer generated 3-D surface models are created from a database of serial cross-sectional anatomical images. Points chosen on endocardial and epicardial surfaces in each cross-sectional image are processed to create polygons defining myocardial wall boundaries. The polygons from adjacent serial images are then combined, to create a 3-D surface model. The discrete anatomical locations of unit electrodes on multipoint electrode templates are then assigned in the proper position on the surface model. Computer analysis of simultaneous activation data from each unit electrode is performed based on parameters set by the user. Activation data from each unit electrode site are displayed on the computer surface model in a color spectrum correlating with a user-defined time scale. Activation sequence maps can be visualized as static isochrone maps, interval maps, or as dynamic maps at variable speeds, from any 3-D perspective. Thus, an interactive computerized 3-D display system is described, which allows anatomically superior analysis and interpretation of complex atrial arrhythmias.

    Notes: A Review of Surgery for Atrial Fibrillation. Atrial fibrillation is the most common of all sustained cardiac arrhythmias, yet it has no effective medical or surgical therapy. During the past decade, multipoint computerized electrophysiologic mapping systems were used to map both experimental and human atrial fibrillation. On the basis of these studies, a new surgical procedure was developed for atrial fibrillation. Between September 25, 1987, and July 1, 1991, this procedure was applied in 22 patients with paroxysmal atrial flutter (n = 2), paroxysmal atrial fibrillation (n = 11), or chronic atrial fibrillation (n = 9) of 2 to 21 years duration. All patients were refractory to all antiarrhythmic medications, and each patient failed to receive the desired therapeutic benefits of an average of five drugs administered preoperatively. There were no operative deaths and all perioperative morbidity resolved. All 22 patients have been successfully treated for atrial fibrillation with surgery alone. Preservation of atrial transport function has been documented in all patients postoperatively, and all have experienced marked clinical improvement.

    Notes: Abstract  Objectives: The standard Maze procedure has proven to be extremely effective in curing atrial fibrillation in thousands of patients worldwide. Until now it has required a median sternotomy and cardiopulmonary bypass. In order to simplify the standard approach, a minimally invasive technique was developed. We have recently applied this minimally invasive Maze procedure in 72 patients. Methods: The technique is dependent on the use of cryosurgery and the total number of atriotomies has been decreased from twelve to four. In addition to performing the Maze procedure, 32% of patients have had concomitant surgery via the minimally invasive approach including mitral valve repair/replacement and tricuspid valve repair. Results: Perioperative morbidity is improved following the minimally invasive approach in comparison to the standard approach with the incidence of temporary perioperative arrhythmias being decreased by 50%. The long-term recurrence of atrial fibrillation is 2.4% following the minimally invasive Maze procedure and 2.2% following the standard Maze procedure. The incidence of pacemaker requirements following the standard Maze procedure is 20% but only 6% following the minimally invasive Maze procedure. Both right atrial and left atrial transport function have been documented in 100% of patients following the minimally invasive Maze procedure. Conclusions: We believe that the minimally invasive Maze procedure is a substantial improvement over the standard approach in terms of patient morbidity while preserving the effectiveness of the Maze procedure in curing atrial fibrillation.

    Notes: Abstract Four controlled studies, one each in Australia, Germany, the United Kingdom, and the United States, involving 30 calves each were conducted to evaluate the effect of simulated rainfall on the efficacy of Ivomec Pour-On against infections of Cooperia spp. At 3 weeks before treatment the calves were infected orally with third-stage larvae of Cooperia spp. In each study a recent, locally derived field isolate was used. The calves were allocated by restricted randomization based on body weight within sex to one of the following treatments: unmedicated control with no rain, Ivomec Pour-On with no rain, Ivomec Pour-On with rain starting at 40 min before treatment, Ivomec Pour-On with rain starting at 10 min after treatment, and Ivomec Pour-On with rain starting at 60 min after treatment. Ivomec Pour-On was applied topically at a dose rate of 1 ml/10 kg body weight (500 μg ivermectin/kg body weight). The simulated rainfall was equivalent to a heavy shower of approximately 12.5 mm of water during a 30-min period. The calves were necropsied for worm counting at 14 or 15 days after treatment. An evaluation of the pooled data showed that as compared with the untreated controls, the Ivomec Pour-On-treated calves with no rain had significantly (P 〈 0.01) fewer C. oncophora (〉99%), C. punctata (〉99%), C. surnabada (〉98%), and combined Cooperia spp. (〉99%). The reduction in Cooperia numbers noted for calves exposed to simulated rainfall was 〉96% for all Cooperia species, regardless of when the rainfall started relative to the application of Ivomec Pour-On. There was no significant (P 〉 0.1) difference between the Ivomec Pour-On-treated calves with no rain and the pooled groups with simulated rainfall or between the group with rain before treatment and the pooled groups with rain after treatment. Ivomec Pour-On was highly effective against established infections of Cooperia spp. when applied to wet animals or to animals becoming wet shortly after treatment.
