RESUMO
@#Pulmonary arterial hypertension (PAH) is a severe, progressive disease leading to right ventricular failure and finally death. Lung transplantation is recommended for PAH patients who do not respond to targeted drug combination therapy or World Health Organization functional class (WHO FC) Ⅲ or Ⅳ. However, only 3% of PAH patients can recieve the lung transplantation. A novel implantable interatrial shunt device (ISD) can create a relatively fixed right-to-left shunt established by balloon atrial septostomy (BAS). The device may decompress the right sided chambers, facilitate left heart filling, improve organ perfusion and reduce the likelihood of syncope, acute pulmonary hypertensive crisis and death. The systemic oxygen transport improves despite hypoxemia. Implantation is simple, feasible and safe, and the X-ray time and operation time are short. There is no severe complication or thrombosis during the mid-term follow-up of the clinical studies and the device remained patent. The syncope symptoms, six-minute walk distance, cardiac index and systemic oxygen transport improve significantly in the patients. ISD may be currently the last alternative treatment to improve symptoms and prolong survival in currently drug-resistant patients with severe PAH.
RESUMO
A nonrestrictive interatrial communication is mandatory in some patients with complex cyanotic heart disease. Up to the present time, Park blade atrial septostomy with a Park blade catheter is performed only under fluoroscopic guidance. We successfully monitored only under transthoracic 2-dimensional (2D) echocardiography (TTE), in a 7-week-old infant with d-Transposition of Great Arteries (d-TGA), a restrictive patent foramen ovale (PFO), and small ventricular septal defect (VSD), who presented with severe hypoxemia. TTE confirmed the position of the blade before and during pullback to the right atrium, followed by balloon septoplasty. There was an adequate enlargement of the interatrial communication with subsequent improvement in the oxygenation of the infant. This is the first reported case of the performance of blade atrial septostomy as a bedside TTE guided procedure here in the Philippines.

La presencia de una comunicación interauricular no restrictiva es obligatoria para mantener un gasto cardíaco adecuado o para lograr una mezcla de sangre aceptable en algunos pacientes portadores de cardiopatías congénitas complejas. Describimos un paciente en quien luego de un intento fallido de dilatación estática con balón de una comunicación interauricular restrictiva se utilizó un balón con cuchillas con éxito para su ampliación.
A nonrestrictive atrial septal defect is mandatory in order to maintain an adequate cardiac output or to achieve an acceptable blood mixing in some patients with complex congenital heart defects. We successfully performed a blade balloon septostomy in a patient with a restrictive atrial septal defect who had previously undergone a failed static balloon dilation of the atrial septum.
RESUMO
La hipertensión arterial pulmonar es una enfermedad rara que afecta a personas de mediana edad, predominando en el sexo femenino. La sobrevida es de 2,8 años, luego del diagnóstico. Desde el año 1980 (donde se realizó el primer trasplante pulmonar) hasta la fecha, el tratamiento médico presentó un gran progreso, lo que ha relegado a los tratamientos intervensionistas, como la septostomía, a un segundo plano.La primer septostomía fue realizada en el año1983 y hasta la actualidad sólo se realizaron aproximadamente 300 procedimientos en todo el mundo. Por este motivo presentamos un caso clínico donde el tratamiento intervencionista por medio de la septostomía auricular nos muestra una solución transitoria como puente hacia el trasplante pulmonar
The pulmonary hypertension is a rare disease that affects peoplein the third and fourth decade of life; the predominance is in female sex. Since the first pulmonary transplant, made in 1980, de medical treatment and the interventional procedures have had a great progress. The first septostomy was in 1983 and nowadays, there have been 300 septostomies around the world. We introduced a case report of a septostomy like a bridge to a pulmonary transplant
A hipertensão arterial pulmonar é uma doença rara que afeta a pessoas de meia idade, predominando o sexo feminino. Estudos epidemiológicos mostrarão que o diagnóstico realiza-se 2 anos depois do inicio dos sintomas e a sobrevida é de 2,8 anos logo do diagnóstico. Mas, em pacientes em classe funcional IV a mesma diminui a 6 meses. Desde o ano 1980 (onde se realizou o primeiro transplante pulmonar) até a data, o tratamento médico apresentou um grande progresso, o que há relegado aos tratamentos intervencionistas como a septostomía em um segundo plano e o seu desuso. A primeira septostomía foi realizada no ano 1983 e até hoje só foram realizados aproximadamente 300 procedimentos em todo o mundo. Por esse motivo nós apresentamos um caso clínico, onde o tratamento intervencionista pelo meio da septostomía auricular nos mostra uma solução transitória mas efetiva como ponte até o transplante pulmonar

Endoscopic surgery is popular in the neurosurgical field. The purpose of this study was to determine the role of endoscopy in obstructive hydrocephalus. From 1989 to 1999, we performed 81 endoscopic third ventriculostomies and 10 septostomies. Seventy-one of 81 operations were performed with endoscopic third ventriculostomy alone and 10 patients had endoscopic third ventriculostomy and ventriculoperitoneal shunt simultaneously. Age distribution varied from 2 months to 62 years of age. Our selection criteria included aqueductal stenosis (39 patients) and obstructive hydrocephalus due to tumor or cyst (42 patients). The most common candidate for endoscopic septostomy was atresia of the foramen of Monro (4 patients). Endoscopic septostomy was also performed to simplify shunting in patient; with multiseptated ventricle due to shunt infection, germinoma, thalamic tumor, craniopharyngioma, cyst and brain abscess. Sixty-five of 71 patients who were treated with endoscopic third ventriculostomy alone showed successful results (91.5%). However, 6 patients had unsatisfactory results and they needed a ventriculoperitoneal shunt. With no mortality, transient surgical complications were observed in 7 patients: 2 transient diabetes insipidus from electrical injury to the pituitary stalk, 1 epidural hematoma from sudden drainage of CSF, 1 delayed intraventricular hemorrhage. 2 obstruction of fenestration site and 1 transient memory disturbance from injury to the fornix. Endoscopic septostomy was useful in simplifying shunting in all cases with complicated hydrocephalus. Endoscopic surgery is straightforward and effective in appropriately selected cases with obstructive by drocephalus.
