The persistence of false lumen after surgical repair of aortic dissection is frequent. This event has a negative impact on the prognosis and is secondary to the persistence of unrepaired entry sites and of dissected major aortic branches. We describe three cases in which visualization of a dissected celiac trunk with an anomalous flow pattern was possible with transesoghageal echocardiography. Two of these cases died in the early postoperative period and the echo findings were confirmed at necropsy. We suggest that visualization of anomalous pattern flow in the celiac trunk is of prognostic relevance because it plays a major role in mantaining the false lumen persistence and, therefore, should be part of the routine examination after surgical repair of aortic dissection. 相似文献

Ivabradine is indicated in cardiac failure and ischemia to reduce sinus rate by inhibition of the pacemaker I(f) current in sinoatrial node. We report a case of an 18‐year‐old woman with left atrial tachyarrhythmia resistant to several antiarrhythmic drugs and to electric cardioversion who responded only to ivabradine, which significantly reduced heart rate without abolishing the arrhythmia itself. An ectopic focus in the ostium of left pulmonary veins was found and the patient was successfully ablated. We suggest that ivabradine might be therefore useful in the treatment of supraventricular tachyarrhythmias due to an enhanced automaticity. 相似文献

During the preparation of the NK-2 selective tachykinin antagonist MEN 10208 (Thr-Asp-Tyr-D-Trp-Val-D-Trp-D-Trp-Arg-NH2) and its analogs by the solid-phase method employing the Boc strategy routinely used in our laboratory, we encountered difficulties in the coupling of hydrophobic amino acids D-Trp and Val. To study the coupling problems several syntheses of MEN 10208 and analogs were carried out with different activation strategies. These syntheses yielded considerable amounts of deletion sequences even though a negative Kaiser test was obtained after each coupling. Inaccessibility of the free amino group of the growing peptide due to steric hindrance of the hydrophobic residues during coupling, and for the ninhydrin complex during the Kaiser test, may account, at least in part, for the unsatisfactory synthetics results and for the false-negative ninhydrin tests. Repetition of each synthesis with the Fmoc strategy on a newly developed DOD resin for peptide amides using the DCC/HOBt chemistry gave superior results in terms of the yield and purity of the crude peptides. Therefore, the Fmoc strategy appears to offer advantages over the Boc method for the preparation of these peptides containing hydrophobic amino acids. 相似文献

Seven cases of ventricular cross stimulation from a group of 23 patients implanted with DDD devices are presented. In two patients the phenomenon was observed at the moment of DDD programming at nominal values, and in five other patients it was reproduced by increasing the atrial output voltage up to ten volts. In all 23 patients cross stimulation disappeared permanently within 24 hours after implantation. From the onset of cross stimulation to its end, atrial and ventricular threshold voltages were unchanged, while the atrial and ventricular impedances significantly decreased. These results suggest that an important role in the phenomenon occurs by impedance variation at the interface between the pulse generator and body tissue. 相似文献
