Comparison of Different Procedural Approaches for Left Atrial Appendage Closure: Searching for Simplicity
To assess procedural and long-term efficacy and safety of two alternative methods for appendage closure, conscious sedation
with standard transoesophageal echo and procedure guided by rotational angiography. Background. Demand for appendage
closure is increasing, and a reasonable time-response should be given to nonvalvular atrial fibrillation patients not suitable to
receive anticoagulation. General anesthesia and the need for an anesthesiologist are limiting factors to improve procedure
availability; it is time to introduce simpler approaches. Methods. Single center experience in appendage closure during 9 years,
using three different procedural approaches: general anesthesia with echo guidance, conscious sedation with echo guidance, and
rotational angiography guidance. Conscious sedation and rotational angiography-guided procedures were performed in the
absence of an anesthesiologist. Procedural characteristics and follow-up events were recorded. Results. 260 consecutive appendage
closure procedures were reviewed: 155 were performed under general anesthesia (59.6%), 71 were performed with conscious
sedation (27.3%), and 34 were rotational angiography guided (13.1%). Device success rate for procedures guided by rotational
angiography was significantly lower than that for general anesthesia and conscious sedation (91.2% versus 100% versus 98.6%,
p � 0.001) because there was a greater need to recapture and change device size. However, final procedural success was high and
without difference between approaches (98.8% versus 97.2% versus 100%, for general anesthesia, conscious sedation, and rotational
angiography, respectively); with a median follow-up of 17 months (CI 95% 13–23 month) (637.9 patients-year), there was
no difference among approaches for thromboembolic (1.3 versus 1.8 versus 1.8) and major bleeding events (3.2 versus 2.8 versus
1.8), respectively. Conclusions. Appendage closure performed, either with conscious sedation with echo guidance or rotational
angiography guided, is feasible, with no difference in procedural success and follow-up events compared with general anesthesia
and without the limitation of the need for an anesthesiologist on-site
A 70-Year-Old Woman With a Prosthetic Mitral Valve and Sudden Chest Pain.
A 70-year-old woman presented to the ED with oppressive ongoing chest pain that had lasted for 1 hour and was accompanied by intense sweating. The patient had a previous history of bronchial asthma, severe degenerative mitral regurgitation, and an ostium secundum atrial septal defect that had been treated 6 years ago with a prosthetic mechanical mitral valve, Bicarbon 25, and an atrial septal defect closure. She was being treated with ciclesonide, tiotropium bromide, olodaterol, theophylline, and warfarin, adjusted according to the international normalized ratio. Two weeks before the current event, because of trauma suffered in her leg, her primary care physician changed her treatment to subcutaneous enoxaparin, 80 mg once daily. Considering that her weight was 80 kg and her renal function was normal, the dose of enoxaparin prescribed was subtherapeutic for a mechanical prosthetic valve
Dehiscencia de anillo valvular mitral y su relación con técnicas hipercorrectoras: reporte de un caso
La reparación de la válvula mitral es el método de elección para el tratamiento de la enfermedad degenerativa valvular, siendo la anuloplastia fundamental para lograr buenos resultados a largo plazo. Presentamos un caso de dehiscencia del anillo un año después de su intervención, que provocó una nueva regurgitación siendo esta severa. Creemos que fue debido a la excesiva tensión en el anulus posterior. La reintervención se realizó a través de toracotomía derecha, se realizaron re-reparación, anuloplastia con anillo y refuerzo con sutura del anulus posterior

Incidence and risk factors of aplastic anemia in Latin American countries: the LATIN case-control study
Associations between aplastic anemia and numerous drugs, pesticides and chemicals have been reported. This study conducted in Latin American countries shows a low incidence of aplastic anemia in this region of the world. Frequent exposure to benzene-based products increases this risk, while any association with specific drugs is uncertain
