Role of intraoperative echo-Doppler color echocardiography in cardiac surgery. Preliminary study

Intraoperative echocardiography with Doppler color flow imaging technique can provide the surgeon with an immediate and direct assessment of cardiac anatomy and function. To determine the utility of this recent technique, we have examined 15 patients pre, per, and postoperatively with Doppler color flow imaging. The intraoperative study was performed before and after cardiopulmonary bypass. A sterile transducer was placed directly on the epicardial surface of the heart, and multiple views were recorded. Intraoperative echocardiography with Doppler color flow imaging technique demonstrated excellent correlation with preoperative and postoperative findings, allowing an immediate evaluation of the surgical results. These preliminary results suggest that intraoperative Doppler color flow imaging technique is a valuable adjunct in heart surgery. It is particularly useful in valve repair, and in surgical repair of congenital heart disease.     

Coronary angioplasty with a rotary atherotome]

Several new coronary dilatation systems, including those using laser energy, atherectomy devices and stent implantation, are being developed as alternative or complementary procedures to coronary artery balloon angioplasty. We report our initial experience performing coronary angioplasty with a new rotational atherectomy device, the transluminal extraction catheter, which simultaneously cut and aspirate fragments from the atherosclerotic plaque. The components of the whole system are a special guidewire to cross the stenosis, the atherectomy catheter and the conduction-control unit. This unit, connected when the atherectomy catheter is positioned across the lesion, produces rotation of the conical bladder located in the catheter distal tip and simultaneous aspiration of residual particles. The procedure was performed in 11 patients in whom 13 lesions were dilated. All patients were male (mean age 55 +/- 23 years, range 45-77). The reason for the angioplasty was stable angina in 2 patients and unstable angina in the remaining seven. Initial success (residual stenosis less than 50% of vessel diameter) was obtained in 10 of 13 lesions. In two, conventional balloon angioplasty was required to improve atherectomy result. The only unsuccessful procedure was in a proximal right coronary artery venous graft, in which a large dissection occurred. Patient had angina but no myocardial infarction. Pathologic examination of aspirated material revealed fibrous tissue in 12 cases and cholesterol crystals in four. We conclude, with the limitation of a preliminary study, that rotational atherectomy with the transluminal extraction catheter is a useful procedure to relief coronary stenosis of the coronary arteries.     

Recomendaciones de la Sociedad Española de Reumatología sobre el uso de terapias biológicas en espondiloartritis axial

Objective

Recent data published on biological therapy in axial spondyloarthritis (axSpA) since the last publication of the recommendations of the Spanish Society of Rheumatology (SER) has led to the generation of a review of these recommendations based on the best possible evidence. These recommendations should be a reference for rheumatologists and those involved in the treatment of patients with axSpA.

Comparison of results of percutaneous transluminal coronary angioplasty with and without selective requirement of surgical standby.

To determine the outcome of percutaneous transluminal coronary angioplasty (PTCA) with the use of 2 different strategies of surgical coverage, the results of 1,283 consecutive PTCAs were analyzed. In 269 procedures (21%) (patients considered at high risk should acute vessel closure occur--standby group) the operating room and the surgical team were ready for an immediate intervention. In the remaining 1,014 procedures (79%) (backup group), although the surgical team was "in house," they were not necessarily ready for an immediate intervention. Mean age of the population was 58 +/- 10 years and 84% of patients were men. Coronary risk factors, medical treatment, clinical indication for PTCA, previous coronary surgery and left ventricular ejection fraction were similar in both groups. Dilatation was more frequently multiple (23 vs 16%, p less than 0.05), or performed in the left anterior descending coronary artery (71 vs 46%, p less than 0.001), in bypass grafts (4 vs 2%, p less than 0.02), in proximal coronary segments (72 vs 57%, p less than 0.001) or in lesions at bifurcation (35 vs 28%, p less than 0.02) in the standby than in the backup group, respectively. PTCAs were less frequently performed during the same diagnostic procedure (15 vs 34%, p less than 0.001) in the standby group. Angiographic success was obtained in 91 and 92% of the attempted lesions and PTCA success in 89 and 88% of the procedures in the standby and backup groups, respectively. The incidence of death (1 vs 0.7%), acute myocardial infarction (2.9 vs 2.7%) and emergency surgery (0.7 vs 0.1%) was also similar in both groups.(ABSTRACT TRUNCATED AT 250 WORDS)
