Inadvertent endocardial lead malposition is recognized as a rare incident which is usually underreported and if recognized during implantation can be easily corrected. This phenomenon is caused by the ventricular lead unintentionally crossing a pre-existing patent foremen ovale, septal defects (atrial or ventricular) or directly from the aorta via an accidental subclavian puncture resulting in the lead implanting into the left ventricle. While this is a rare occurrence we report, the incidental finding of pacemaker lead malposition during a routine follow-up transthoracic echocardiogram and the benefits of three-dimensional transesophageal echocardiography in this patient prior to lead extraction. 相似文献

Recently, there has been an increasingly minimalistic approach to transcatheter aortic valve replacement (TAVR), with most procedures now performed under conscious sedation without real time transesophageal echocardiography (TEE) guidance. Proponents of echo should not feel discouraged by this; it is the initial insights that were gained with procedural TEE during the early years of TAVR that have allowed the procedure's gradual maturation and sophistication. Experienced centers that have promoted extensive TAVR TEE programs continue to maximize the benefits of echocardiography in both procedural planning and execution. Critical to this is the understanding of 3D TEE, allowing the annulus to be sized accurately, relevant neighboring anatomy defined, and complications flagged. This review will outline the current application of 3D TEE in TAVR and discuss challenges and opportunities for 3D echocardiography in this field. 相似文献

Aims
Emergency admission to hospital is associated with an economic burden and mortality. Echocardiography is often the first‐line cardiovascular imaging investigation. Repeat testing is common; however, there are sparse data on the prevalence, appropriateness, or outcome of repeat testing.Methods
We performed an electronic database search for patients with emergency admissions to our institution in February 2015. An electronic patient record review of inpatient echocardiograms was undertaken. Indications for echocardiography were classified as appropriate, may be appropriate, or rarely appropriate. One‐year follow‐up for repeat testing and mortality was investigated.Results
A total of 409 of 2306 (17.7%) unplanned/emergency admissions underwent inpatient echocardiography. Abnormalities were identified in 165/409 (40.3%) of these patients; 154 of 409 (37.7%) had a repeat echocardiogram within the next year. Rarely appropriate indications for echocardiography occurred in 51 (33%) of repeat vs 53 (16%) of index echocardiograms, P < .0001. Repeat testing was associated with a change in findings in 17/154 (11%) patients overall. All of whom had an abnormal index echocardiogram and had an appropriate indication. There was no difference in mean survival time between patients who underwent repeat and those who only underwent a single index echocardiogram (310 days vs 327 days), P = .34.Conclusion
Inpatient echocardiography in emergency hospital admissions identifies clinically important pathology. Repeated testing is common within 1 year of hospital admission. New diagnostic findings occurred in 11% of patients and only in patients with appropriate studies and an abnormal index echocardiogram. Identification of methods to reduce repeat testing and implement appropriateness criteria is warranted. 相似文献96.

Cerebral cavernous malformations (CCM) are collections of enlarged capillaries with irregular structure, located in the brain or spinal cord, that can be life-threatening. We describe a neurologically asymptomatic 15-year-old boy who presented with cutaneous venous malformations (CVM) that developed in adolescence. Owing to his family history of CCM, genetic testing was obtained and confirmed a new mutation in the CCM3 (PDCD10) gene. Brain imaging showed multiple CCM. Although currently asymptomatic, he will continue to be monitored annually by neurology to assess for symptoms of intracranial hemorrhage (ICH) that would warrant investigation with MRI. 相似文献
