Delayed two-step free wall rupture of the right and left ventricular wall after myocardial infarction

We present a 68-year-old female who suffered extensive complications after severe myocardial infarction (MI) in the circumflex (CX) territory. At 24 hours after the initial event, the patient presented with a covered right ventricular free wall rupture (FWR) which was followed by a rupture of the left posterior wall ten days later. We report here on a rare case of delayed two-step biventricular FWR after severe MI in the CX territory.

Low-dose CT coronary angiography in the step-and-shoot mode: diagnostic performance

OBJECTIVE

To investigate the performance of low-dose, dual-source computed tomography (DSCT) coronary angiography in the step-and-shoot (SAS) mode for the diagnosis of significant coronary artery stenoses in comparison with conventional coronary angiography (CCA).

DESIGN, SETTING AND PATIENTS

Prospective, single-centre study conducted in a referral centre enrolling 120 patients (71 men, mean (SD) age 68 (9) years, mean (SD) body mass index 26.2 (3.2) kg/m2). All study participants underwent DSCT in the SAS mode and CCA within 14 days. Twenty-seven patients were given intravenous beta blockers for heart rate reduction before CT. Patients were excluded if a target heart rate <or=70 bpm could not be achieved by beta blockers or when the patients were in non-sinus rhythm. Two blinded readers independently evaluated coronary artery segments for assessability and for the presence of significant (>50%) stenoses. Sensitivity, specificity, negative (NPV) and positive predictive values (PPV) were determined, with CCA being the standard of reference. Radiation dose values were calculated.

RESULTS

DSCT coronary angiography in the SAS mode was successfully performed in all 120 patients. Mean (SD) heart rate during scanning was 59 (6) bpm (range 44-69). 1773/1803 coronary segments (98%) were depicted with a diagnostic image quality in 109/120 patients (91%). The overall patient-based sensitivity, specificity, PPV and NPV for the diagnosis of significant stenoses were 100%, 93%, 94% and 100%, respectively. The mean (SD) effective dose of the CT protocol was 2.5 (0.8) mSv (range 1.2-4.4).

CONCLUSIONS

DSCT coronary angiography in the SAS mode allows, in selected patients with a regular heart rate, the accurate diagnosis of significant coronary stenoses at a low radiation dose.

Participation of oncological outpatients in psychosocial support

In total, 132 cancer patients in four oncology outpatient clinics in Hamburg completed a questionnaire consisting of a newly designed instrument for measuring psychosocial support. In this questionnaire, patients were asked about their knowledge of institutions offering support, their previous participation in psychosocial support, the reasons for participation and their experience with and attitude towards it. A second section consisted of standardized instruments: the EORTC QLQ-C30 questionnaire (Aaronson), the Brief Symptom Inventory (Derogatis and Melisaratos), the List of Physical Complaints (von Zerssen and Koller) and the Impact of Event Scale (Horowitz). Descriptive and variance-analytical methods were used for the analysis of results. Most respondents were women (88%). The largest group (72%) had a history of breast cancer. A total of 28% of the patients in the sample had participated in psychosocial support, about 4% of these in self-help groups. Participants in psychosocial support did not differ from non-participants in gender, but they were significantly younger. They showed considerably higher scores in emotional and physical distress than non-participants, their attitude towards psychosocial support was more positive, and they had more knowledge about institutions offering support than non-participants. The main reasons listed for their participation in psychosocial support were mental distress, a desire to obtain help, and the wish to cope with the illness. The main reason for not participating was sufficient support from the family, friends or doctors.
