Abstract

From 71 consecutive patients with paracardiac neoplastic masses who underwent transesophageal echocardiography (TEE), obstruction of individual right upper pulmonary venous flow by compression by contiguous mass was detected by TEE in 4 patients before and disappeared after anti-neoplastic treatments. Pulmonary vein, contiguous neoplastic mass and their relation could be clearly visualized and assessed by TEE. Pulmonary venous obstruction was assessed as moderate degree by combination of Doppler flow characteristics and diameter of pulmonary vein. Before therapy, peak velocities and time-velocity integrals in obstructed right upper pulmonary venous flow were increased, whereas deceleration times of systolic flow were prolonged. After therapy, peak velocities and time-velocity integrals were reduced and deceleration times of systolic flow were shortened, with normalization of the diameter of the right upper pulmonary veins. Thus, TEE may be used to detect and evaluate pulmoury venous obstruction by neoplastic masses and its changes after antineoplastic treatments.

20. STUDIES OF MYOCARDIAL CONTRACTILE PROTEINS AND MITOCHONDRIAL SUCCINATE DEHYDROGENASE DURING PARTIAL HEART-LUNG BYPASS.

Abstract

Myocardial actin-myosin systems, cardiac mitochondrial succinate dehydrogenase activity and the adenosine nucleotides-creatine phosphate levels of the heart muscle have been studied in groups of dogs after isovolemic 3-hour partial heart-lung bypass procedures (at the flow rate of about half of the cardiac output rate) and after 3-hour bypass and 4-week recovery period, and these results have been compared with the findings in the control group. Cardiac contractile proteins remain intact; however, the succinate dehydrogenase activity is decreased immediately after the bypass, but this change is reversible. The myocardial energy-rich phosphate levels are at their constant level. [ABSTRACT FROM AUTHOR]

21. Sensitivity and Specificity of Electrocardiographic ST-T Changes as Markers of Neoplastic Myocardial Infiltration

Author

Lestuzzi, Chiara, Nicolosi, Gian Luigi, Biasi, Salvatore, Piotti, Patrizia, and Zanuttini, Domenico

Abstract

We evaluated the correlations between electrocardiographic ST-T changes (negative T waves, ST segment elevation) and echocardiographic diagnosis of neoplastic infiltration of the myocardium in 95 patients with neoplastic masses in contact with the heart. We compared echocardiographic results to computed tomography, nuclear magnetic resonance, surgery or autopsy data in 49 patients: the concordance was 86 percent. Significant ST-T changes were present in 77.7 percent of the patients with myocardial infiltration at echocardiography. The “false negatives” (normal ECC, nonspecific changes) were mainly related to infiltration limited to the right side of the heart; in some of these cases, the appearance of right bundle branch block was observed. The “false positives” (ST-T changes without echocardiographic signs of infiltration) were observed in the older patients and in those with pericardial effusion or other heart diseases. The ST segment elevation was a more specific sign of myocardial infiltration as compared to negative T waves (86 vs 47 percent). A progression or the disappearance of electrocardiographic and echocardiographic abnormalities was observed during follow-up in 24 cases. Serial electrocardiograms are useful for screening in clinical settings in neoplastic patients; the appearance of ST-T changes or of conduction disturbances should suggest the need for two-dimensional echocardiography in order to define the diagnosis.

22. Secondary neoplastic infiltration of the myocardium diagnosed by two-dimensional echocardiography in seven cases with anatomic confirmation

Author

Lestuzzi, Chiara, Biasi, Salvatore, Nicolosi, Gian Luigi, Lodeville, Daniela, Pavan, Daniela, Collazzo, Raffaele, Guindani, Antonio, and Zanuttini, Domenico

Abstract

In seven patients with different types of neoplasm, secondary myocardial infiltration was diagnosed in vivo by two-dimensional echocardiography and confirmed by direct inspection. In all patients, clinical and electrocardiographic findings were suggestive but nonspecific for myocardial involvement. Two patients had cardiac tamponade and three had pericardial effusion. In three patients, the echocardiographic diagnosis made it possible to plan specific therapy.
