ABSTRACT
Atrial septal defect (ASD) is one of the common congenital anomalies of the heart in humans. Its complications depend on the size of the defect and can manifest at any age. The common symptoms of ASD include dyspnea and fatigue. Most of the ASDs are associated with morbidity and mortality, Earlier the treatment, it is better to the patient. I saw a large ostium secundum defect in the heart of an adult female cadaver during dissection classes for undergraduate medical students. The interatrial septum had large defect at the region where fossa ovalis should have been located. It was about 1.25 inches in diameter and oval in shape. This type of large septal defect might result in cyanosis, stroke or death of the patient at any age.

Objective:To study the application value of echocardiography in transcatheter atrial septal defect closure.Methods: Chosen 2012-2014 years our hospital 68 patients with transcatheter atrial septum closure, using the thoracic echocardiography in patients with transcatheter atrial septum closure under general anesthesia guided and cardiac function monitoring.Results: All 68 patients with atrial septal defects under the guidance and monitoring via thoracic echocardiography defect plugging successfully completed, the average operation time was (23.8±4.7)min; the average hospitalization day was (5.2±1.3)day. Three days, 3 months after operation, right ventricular end-diastolic diameters were narrowing (t=11.232,t=16.589;P<0.05); The right atrium insides were narrowing (t=10.573,t=14.793;P<0.05); left ventricular end-diastolic diameters, were increasing (t=9.378,t=12.245;P<0.05); pulmonary artery diameters were narrowing (t=10.026,t=13.873;P<0.05).Conclusion:Echocardiography can do the entire guide, cardiac function monitoring in transcatheter atrial septal defect closure, postoperative follow-up and curative effect evaluation.
ABSTRACT
Lipomatous hypertrophy of the interatrial septum (LHIS) is an uncommon cause of superior vena cava syndrome (SVCS). Fibrosing mediastinal lymphadenopathy is another cause of SVCS. We present a 65‑year‑old female patient with a history of tuberculosis (TB) and the coexistence of LHIS and fibrosing mediastinitis due to TB of the lung. Fibrosing or sclerosing mediastinitis is a rare entity with few cases published in the western literature. She presented with mild symptomatology of SVCS and she underwent on transthoracic and transesophageal echocardiography, computed tomography scan, magnetic resonance imaging, and venography. Due to the development of an abundant collateral venous system seen on venography and her negation for any treatment, she did not undergo yet on any intervention. To our knowledge, this is the first case reported in the international bibliography in which LHIS and sclerosing lymphadenopathy are simultaneously diagnosed in the same patient.

Introducción A pesar de que es técnicamente más demandante, el acceso a la válvula mitral por vía transeptal permite una exposición mayor de sus valvas y del aparato subvalvular, en especial en aurículas pequeñas, en reoperaciones o cuando se combina con el tratamiento de la válvula tricuspídea. Objetivos Evaluar las dificultades técnicas y las complicaciones asociadas con el abordaje transeptal para el reemplazo valvular mitral. Material y métodos Entre 2006 y 2009 se incluyeron 62 pacientes consecutivos a los que se les realizó reemplazo valvular mitral solo o asociado con revascularización miocárdica a través de un abordaje transeptal extendido al techo de la aurícula izquierda. Se evaluaron las dificultades técnicas y la morbimortalidad del procedimiento. Resultados En todos los pacientes se pudo realizar el abordaje sin dificultades técnicas con una exposición adecuada de la válvula mitral. La tasa de trastornos de conducción en el posoperatorio fue del 9,7% y la necesidad de implante de un marcapasos definitivo fue del 4,8%. De los pacientes que tenían fibrilación auricular previa (n = 18), el 83,3% recuperaron ritmo sinusal o nodal alto en el posoperatorio. Conclusiones El abordaje transeptal extendido al techo de la aurícula izquierda constituyó una alternativa de acceso a la válvula mitral, con una exposición mejor que el abordaje tradicional, aunque a expensas de una técnica más demandante. Los tiempos quirúrgicos, la mortalidad y las complicaciones fueron similares a los de la técnica convencional, a excepción de una probable incidencia mayor de ritmo nodal y bloqueo A-V. Posiblemente exista cierto beneficio en la recuperación del ritmo sinusal en los pacientes con fibrilación auricular crónica previa.
Background Despite mitral valve replacement through a transseptal approach requires technical expertise, it allows a better exposure of the mitral leaflets and subvalvular apparatus, especially when left atrium is small, during reoperations or in combination with tricuspid valve interventions. Objectives To evaluate the technical difficulties and complications associated with the transseptal approach for mitral valve replacement. Material and Methods Between 2006 and 2009 we included 62 consecutive patients undergoing isolated mitral valve replacement or associated with myocardial revascularization through a transseptal approach extended to the left atrium roof. Technical difficulties, morbidity and mortality related to the procedure were evaluated. Results The procedure did not show technical difficulties and the mitral valve was properly exposed in all cases. Postoperative conduction abnormalities rate was 9.7% and 4.8% of patients required a permanent pacemaker. In patients with preoperative atrial fibrillation (n=18), 83.3% were in sinus or junctional rhythm after the procedure. Conclusions The extended transseptal approach provided a better exposure of the mitral valve compared to conventional approach; yet technical expertise is required. The operative times and the incidence of mortality and complications were similar to those of the conventional technique, except for a probable greater incidence of junctional rhythm and AV block. Patients with previous atrial fibrillation may have the benefit of sinus rhythm restoration.
