Recommendations for training in performance and interpretation of stress echocardiography. Committee on Physician Training and Education of the American Society of Echocardiography.

Stress echocardiography has emerged as a clinically useful procedure in the management of patients with ischemic heart disease and other conditions. However, the accuracy of this test relies on the ability of those who carry out the technical aspects of the test and depends critically on proper interpretation of the images. Appreciation of wall motion abnormalities is generally acknowledged as one of the most difficult skills to master in echocardiography. There is consensus that this is also one of the most difficult skills to teach. Appreciating stress-induced changes in wall motion, which sometimes are subtle, requires a significant commitment to initial training in this skill and its maintenance. This document provides recommendations for physician training in stress echocardiography.

Cheyne-Stokes respiration in patients recovering from acute cardiogenic pulmonary edema.

Cheyne-Stokes respiration is characterized by crescendo-decrescendo fluctuations in tidal volume and respiratory rate interrupted by central apneas. It has long been associated with cardiac disease and has often been cited as a poor prognostic indicator, yet the incidence and immediate significance of CSR in the setting of acute cardiogenic PE is not well defined. Therefore, we studied 95 patients who required MVS because of PE. Breathing patterns were monitored by continuous respiratory inductive plethysmography for a minimum of 12 hours of spontaneous respiration after recovery from PE; CSR was noted in 42 patients (44 percent). There were no significant differences between patients with PE and CSR and those with only PE in regard to LVEF (mean +/- SD, 36 +/- 18 percent vs 33 +/- 16 percent; p = 0.55), reinstitution of MVS within 48 hours (4.8 percent vs 17.0 percent; p = 0.065), or in-hospital mortality (16.7 percent vs 26.4 percent; p = 0.255). We conclude that CSR is a relatively common breathing pattern in patients who required MVS because of cardiogenic PE and does not portend a poor immediate prognosis in this population.

Coronary sinus pacer lead simulating left atrial mass.

M-mode and two-dimensional echocardiographic evaluation of a patient with rheumatic heart disease and an atrioventricular sequential pacemaker with a coronary sinus lead showed an echo-producing mass in the left atrium. A repeat study after the coronary sinus lead was replaced by a right atrial screw-in lead revealed the disappearance of the echo-producing mass.
