An independent 98 year-old man was admitted to our hospital for symptoms of progressive weakness with disorientation and dysphasia. Carotid Duplex ultrasonography was performed which revealed a totally occluded right internal carotid artery and high grade stenosis of the left internal carotid artery by velocities of 608/240 cm/sec. The patient refused surgical endarterectomy and thus he was referred for carotid artery stenting. Using the femoral artery approach and multiple catheter techniques, access to the common carotid artery could not be accomplished safely. The procedure was aborted and he was therefore brought back to the catheterization laboratory the following day for direct carotid access. Carotid artery stenting was accomplished by using of a 6F sheath percutaneously in the left common carotid, cerebral protection device (CPD) and a Nitinol stent. The patient was discharged the following day without complications. At 14 months follow-up the patient is functional and independent without recurrence of symptoms. Carotid artery stenting via direct access can be accomplished in patients when the femoral artery approach is anatomically prohibitive. In this case of advanced age and the patient’s refusal for surgery, direct carotid access was his only option.展开更多

This systemic precipitants that promote aggressive atherogenesis have been confirmed in multiple studies showing a relationship between atherosclerotic disease in one vascular bed with disease in another. However, the strength of this relationship varies from patient to patient. Thus, the practical utility of the diffuse nature of atheresclerosis is questionable. Ge and colleagues have proposed the use of left main (LM)coronary artery disease as a potential marker for left anterior descending (lAD) atherosclerotic disease. At first thought, this seems useless since the evaluation of the LM (by angiography or IVUS) can just as easily be performed in the LAD so why bother searching for such a surrogate? However, newer (non-invasive) imaging modalifies are making great gains and will be able to reliably image the LM sooner than the LAD (especially the distal LAD) so such a surrogate could have practical applications.展开更多

A retrospective analysis was carried out to elucidate the surgical outcomes of ALCAPA in infants and children using follow-up echocardiography. Methods： From September 2008 to March 2017, 26 children diagnosed with ALCAPA underwent left coronary re-implantation. All surviving patients received echocardiography during follow-up. Results： The mortality rate after the operation was 11.5%. Before repair, twenty patients （76.9%） presented with left ventricular （LV） dysfunction. The mean Z-score of the preoperative LV end-diastolic diameter was 4.42 ± 2.09. Mitral regurgitation （MR） was present in all patients. Two patients （7.7%）, both with mitral valve prolapse, underwent mitral valve repair at the time of ALCAPA repair. Two children required postoperative extracorporeal membrane oxygenation. LV function normalized at a median time of 5.3 months （range：0.5–36.0 months）. The Z-score of the LV end-diastolic diameter decreased simultaneously. The degree of MR gradually decreased in all surviving patients.All patients had patency of the proximal left coronary artery confirmed by echocardiography at the most recent follow-up. Six patients （26.1%） showed supravalvar pulmonary stenosis and seven patients （30.4%） showed right pulmonary stenosis during follow-up. Conclusions： Coronary re-implantation was effective for rebuilding a dual coronary system in patients with ALCAPA and resulted in progressive improved LV function and reduced functional MR. Echocardiography was valuable for evaluating the outcomes. LV function, the degree of MR, and possible complications could be detected with follow-up echocardiography.展开更多

The most frequent location is the interatrial septum. We report the clinical case of a myxoma of the left atrium and discuss its epidemiological and therapeutic aspects through a review of the literature. <strong>Observation</strong>: This was a 41-year-old female patient who presented with sudden rotational dizziness associated with vomiting. MRI revealed multiple punctiform bilateral supra and subtentorial strokes of different ages, recent and semi-recent, suggesting an embologenic etiology. Transesophageal echocardiography found a large pedunculated, homogeneous, avascular tumor hanging from the interatrial septum. The patient is operated on urgently under cardiopulmonary bypass for resection of a large tumor located in the left atrium. The pathological examination concluded with the diagnosis of myxoma of the left atrium. The postoperative follow-up was straightforward and the patient was discharged from the hospital via home hospitalization. <strong>Conclusion</strong>: The diagnosis of cardiac myxomas is suspected in the presence of symptoms associated with echocardiographic images of intracardiac masses and confirmed by histological study. Embolic accidents are one of the formidable complications of myxomas. Surgical management is urgent, especially in the presence of predictive morphological features of embolism on echocardiography.展开更多

We here introduce the postoperative management of patients with repair of anomalous ori artery from the pulmonary artery, with an emphasis on its outcome. Methods Reco gin rds of the left coronary of 31 patients with anomalous origin of the left coronary artery from the pulmonary artery receiving surgery from 1998 to 2010 were reviewed retrospectively, 10 of which were treated with the mitral valve surgically at the same time. The age of patients was 4 months to 16 years （m kilograms）, all of which were diagno edian, sed of anomalous origin of the left coronary artery from the pulmonary by echocardiography and cardiac catheterization. After surgery, electrocardiogram, echocardiography, arterial blood pressure, transcutaneous oxygen saturation and central venous pressure were monitored. Common postoperative complications in our group were analysed. And preoperative and postoperative data including area of mitral regurgitation, left ventricular systolic diameter and left ventricular distolic diameter were obtained. Cardiopulmonary bypass time and mechanical ventilation time of postoperative patients with no pneumonia were compared with those with pneumonia. Binary logistic regression was applied for the analysis of the risk factors of postoperative pneumonia. Results Of 31 patients, 30 survived after surgery with early mortality of 3.23%. One patient died of severe low cardiac output syndrome. Mechanical ventilation time was 4 hours to 168 hours hours （mean, 39.68 ± 50.52 hours; median, 18 hours）. ICU stay was 16 hours to 425 hours （mean, 111.65 ± 127.03 hours; median, 44 hours）. In our group, common postoperative complications were myocardial ischemia（n = 12, 36.4%）, infection（n = 11, 33.3%） including pneumonia （n = 10, 30.3%）, postoperative tachyarrhythmia（n = 5, 15.2%）, low postoperative cardiac output（n = 2, 6.1%）, endocarditis（n = 1, 3.0%）. Compared with preop-erative data, postoperative data including area of mitral regurgitation, left ventricular systolic diameter and left ventricular distolic diameter decreased remarkably（P 〈 0.01）, with left ventricular ejection fraction significantly improved （P 〈 0.05）. Compared with mechanical ventilation time of patients with no postoperative pneumonia, time of those with pneumonia apparently prolonged（P 〈 0.01 ） while cardiopulmonary bypass time extended （P 〈 0.05）. Mechanical ventilation time was a risk factor of postoperative pneumonia （OR = 1.041, OR 95%CI = （1.010, 1.073）. Conclusions Proper therapy strategies according to the knowledge of the ALCAPA disease and the change of postoperative pathology and physiology play an important role in avoiding the postoperative complications and improving postoperative outcomes.展开更多
