17. Isolated mitral replacement with stent-mounted antibiotic-treated aortic allograft valves

Author

Heng, Ming K., Barratt-Boyes, Brian, Agnew, Trevor M., Brandt, Peter W.T., Kerr, Alan R., and Graham, Kenneth J.

Abstract

The results of valve replacement with a stent-mounted antibiotic-treated aortic allograft valve are reported in 129 patients with isolated mitral valve disease. Of these patients, 70 per cent were in N.Y.H.A. Class IV. The hospital mortality rate was 3.9 percent. The cumulative complication-free rate at 5 years was only 37 percent as 21 percent died late, a further 15 percent were alive following reoperation, 4 percent had an embolic episode, 4 percent were alive with important incompetence, and 20 percent had unimportant incompetence. Proved valve failure was due mainly to detachment of the aortic wall remnant of the valve from the pillar of the rigid metal stent (16 percent incidence at 5 years) and methods for preventing this complication are discussed. Because of these complications the use of this device in the mitral position has been discontinued.

18. The Value of Holter Monitoring in Evaluating the Elderly Patient Who Falls

Author

Rosado, Juan A., Rubenstein, Laurence Z., MPH, Robbins, Alan S., Heng, Ming K., Schulman, Barbara L., and Josephson, Karen R.

Abstract

Ambulatory cardiac (Holter) monitoring is often recommended in the routine evaluation of patients who fall; however, the prevalence of arrhythmias in old people is high, and the usefulness of such monitoring is unproven. As part of a large study of institutionalized elderly fallers, we compared Holter findings of fallers (N = 51) with a group of nonfallers (N = 27) having similar medical and demographic characteristics. Prevalence of ventricular arrhythmias was 82% in each group, and all patients had supraventricular arrhythmias. The mean number of ventricular and supraventricular couplets and runs did not differ between groups. There was no difference in severity of arrhythmias between fallers and nonfallers; in fact, fallers had slightly fewer Lown 4B arrhythmias than nonfallers (10% vs 18%, NS). Prevalence of heart disease was 78% in both groups and was associated with increased ventricular ectopy in the form of runs and couplets (P < .05). No symptoms were reported during the Holter monitoring. We conclude that Holter monitoring should not be a routine part of the work‐up of the patient who falls.

19. Blood pressure and electrocardiographic response to dental treatment with use of local anesthesia

Author

Hasse, Allen L., Heng, Ming K., and Garrett, Neal R.

Abstract

The incidence of ST segment depression during tooth extraction was significantly higher in patients with cardiac disease than it was in patients without cardiac disease, indicating that the cardiac patients experienced myocardial ischemia. The almost equivalent incidence o f ST segment depression during anesthetic administration and surgery suggests that the administration of local anesthetic is as stressful as tooth extraction for cardiac patients. Medical consultation before dental treatment and use of stress-reduction techniques may be indicated for patients with or suspected to have cardiac disease.
