Safety of contrast flash-replenishment stress echocardiography in 500 patients with a chest pain episode of undetermined origin within the last 5 days
Safety concerns regarding the use of echo-contrast agents during baseline and SE in patients with recent chest pain have been raised. The purpose of the present study was to provide evidence regarding the safety of flash-replenishment contrast dipyridamole-atropine echocardiography (DASE) in such patients.
Five hundred consecutive individuals who presented to the Emergency Department with chest pain, normal electrocardiograms (ECG) and troponin I were selected based on a less than 5 days interval between chest pain episode and performance of contrast flash-replenishment DASE. Analysis of myocardial perfusion with SonoVue(C) infusion after dipyridamole was routinely added on top of standard wall motion assessment during DASE. Adverse events (AEs) were reported according to standardized terminology and then compared with a historical control group in which contrast was not used. No deaths, myocardial infarctions, sustained arrhythmias, or any other life-threatening events were observed. Adverse events were not significantly different between the study group and the control group. In the selected subgroup of patients (n = 149) who underwent coronary angiography, accuracy of DASE with additional perfusion assessment was higher (88%, 95% C.I. 83-93%) than without (72%, 95% C.I. 65-79%).
DASE with SonoVue(C) infusion for myocardial perfusion assessment was exceptionally safe even when routinely performed within the first 5 days following a chest pain episode of undetermined origin in subjects without ECG and troponin abnormalities
Right atrial hemangioma
A case of right atrial hemangioma as a rare tumor of the heart is reported. Because of its single, pedunculated mass, surgical excision of the tumor resulted in the complete treatment. Histologically, it was classified as arteriolar type. The importance of recent non-invasive techniques to diagnose these tumors during life is emphasized
Combined cardiac surgery and aneurysm of subrenal abdominal aorta
The authors explain their experience about the combined correction of cardiac pathology and infrarental aortic aneurysm repair. Seven patients of mean age of 63 years underwent simultaneous myocardial revascularization (5 cases) or aortic valve replacement (2 cases) and abdominal aortic aneurysm repair with bifurcated vascular prosthesis (6 cases) and tubular prosthesis (1 case) between 1987 and 1995. Cardiac operation was performed first with a mean number of 2.4 coronary artery by-pass grafts, with a mean by-pass time of 51 min, and a mean abdominal aortic cross-clamp time of 46 min. The mean total operating time was 231 min. All patients were managed postoperatively in the cardiac intensive care unit with a mean duration of 2.5 days and were transfused with a mean of 5 units of donor blood. The mean postoperative hospitalization was 9 days. One patient died for complication of postoperative myocardial infarction. The authors conclude that combined cardiac operation and abdominal aortic aneurysm repair is feasible in carefully selected patients
Effect of Stress Perfusion and Wall Motion Response on Outcome of Obese versus Non-Obese Subjects Without Known Coronary Artery Disease
Prevention of deep venous thrombosis by a new low molecular weight heparin (Fluxum) in cardiac surgery
The prophylactic deep venous antithrombotic efficacy of a low molecular weight heparin (LMWH) was compared with traditional unfractionated calcium heparin in 39 patients submitted to cardiac surgery. The patients were allocated at random to receive either LMWH-Fluxum 3200 IUaXa daily (Group A: 20 patients) or calcium heparin 5000 IU three times daily (Group B: 19 patients). Both treatments were started on the first day after surgery and continued over the fourth postoperative days. One or more risk factors for deep venous thrombosis in addition to the cardiac pathology were present in all the patients of group A and in 13 (72.2%) of group B. Mean times of surgery, blood loss during the perioperative period and number of blood units transfused in both groups were not statistically significant. The deep venous system was investigated by continuous wave Doppler and real time colour Echotomography. No evidence of thrombosis was detected in the two groups. Side effects and subcutaneous hematomas were present in only four patients of group B. Both drugs showed good tolerance, provoking no variations of the main laboratory parameters. We conclude that Fluxum (LMWH) for the efficacy and convenience given by a single daily dose, could represent an alternative choice in the prevention of deep venous thrombosis in cardiac surgery

Ischaemic mitral valve regurgitation: a surgical approach
The aim of this study IS to determine surgical results after surgical mitral valve repair in ischaemic mitral regurgitation. Materials and methods: Between January 1999 and June 2000, 64 patients (5.1% of overall patients) underwent myocardial revascularization and mitral valve surgery. A Cosgrove-Edwards mitral annuloplasty ring was used in 59 cases (92.2%). Average patient age was 64.3±12.4 years (38 males, 21 females). Average degree of mitral regurgitation was 2.8±0.6. Average NYHA class was 3.5±0.5. Average ejection fraction (EF) was 40±12.5 percent. Results: Post-operative 30-day mortality was 3.4% (2 patients). The follow-up was complete for 95 percent (mean 20.4±4.8 months for patients)and data showed an improvement of NYHA class (mean value 1.8±0.2) (p=0.01) and ejection fraction (mean value 51.7±10.2) (p=0.05) with residual mitral regurgitation value of 0.6±0.7. Conclusions: Mitral valve repair in coronary artery disease improves left ventricular function, quality of life and survival rate with low operative risk. Perioperative transesophageal echocardiography has a central role in surgical decision making
2D echocardiographic diagnosis of cardiac tumors surgically treatable.
2D echocardiography allows to detect intracardiac masses as small as 1-2 mm, to define their spatial relationship, mobility and correlates with cardiac structures and with doppler examination quantification of valvular stenosis and regurgitation but cannot help in the histopathologic definition of the mass which can represent benign primitive cardiac tumors as well as secondary tumors of the heart and pericardium and extracardiac tumors, intracardiac thrombi vegetations and more..
