ABSTRACT

OBJECTIVE: To evaluate the initial clinical experience with the Helex septal occluder for percutaneous closure of atrial septal defects. METHODS: Ten patients underwent the procedure, 7 patients with ostium secundum atrial septal defects (ASD) with hemodynamic repercussions and 3 patients with pervious foramen ovale (PFO) and a history of stroke. Mean age was 33.8 years and mean weight was 55.4 kg. Mean diameter by transesophageal echocardiography and mean stretched ASD diameter were 11.33 ± 3.3mm, and 15.2 ± 3.8mm, respectively. The Qp/Qs ratio was 1.9 ± 0.3 in patients with ASD. RESULTS: Eleven occluders were placed because a patient with 2 holes needed 2 devices. It was necessary to retrieve and replace 4 devices in 3 patients. We observed immediate residual shunt (< 2mm) in 4 patients with ASD, and in those with patent foramen ovale total occlusion of the defect occurred. No complications were noted, and all patients were discharged on the following day. After 1 month, 2 patients with ASD experienced trivial residual shunts (1mm). In 1 patient, we observed mild prolapse in the proximal disk in the right atrium, without consequences. CONCLUSION: The Helex septal occluder was safe and effective for occluding small to moderate atrial septal defects. Because the implantation technique is demanding, it requires specific training of the operator. Even so, small technical failures may occur in the beginning of the learning curve, but they do not involve patient safety

ABSTRACT

OBJETIVO: Analisar a experiência inicial no fechamento percutâneo da comunicaçäo interatrial ostium secundum (CIA OS) com a prótese de amplatzer. MÉTODOS: Sete pacientes foram submetidos ao procedimento através da via venosa anterógrada,orientados pela ecocardiografia transesofágica (ETE) e sob anestesia geral. Uma criança era portadora de 2 CIA e de canal arterial (CA). As CIA medidas pelo ETE variaram de 8,7 a 20mm. Um ecocardiograma transtorácico foi realizado na manhä seguinte do procedimento. RESULTADOS: Oito prótese foram implantados nos 7 pacientes com sucesso. Em um paciente, o CA foi ocluído na mesma sessäo com mola de Gianturco, tendo surgido taquicardia supraventricular durante a oclusäo de uma das CIA, controlada com adenosina. Todos receberam alta hospitalar na manhä seguinte, com oclusäo total dos defeitos. CONCLUSÄO: O procedimento mostrou-se seguro, eficaz e versátil, podendo ser considerado como uma alternativa terapêutica inicial em pacientes selecionados com CIA OS.

ABSTRACT

Objetivo - Avaliar a valvoplastia mitral por duplo cateter-baläo como técnica alternativa näo cirúrgica para tratamento da estenose mitral reumática. Método - Duzentos pacientes foram submetidos ao procedimento, sendo 86,5% do sexo feminino, com idade média de 35,2 anos. Oitenta e um por cento estavam em classes funcionais III e IV (NYHA), e 4% exibiam ritmo de fibrilaçäo atrial. Quatro por cento foram submetidos à comissurotomia cirurgica prévia e 7% eram gestantes. Utilizou-se a técnica de dilataçäo com duplo cateter-baläo, após punçäo septal esquerda. Resultados - O procedimento foi realizado com sucesso em 89% dos pacientes. A área valvar mitral aumentou de 0,91 ñ 0,27 para 2,10 ñ 0,47 cm*, p < 0,001; ocorreu reduçäo do gradiente transvalvar mitral de 20,86 ñ 6,16 para 4,26 ñ 3,13 mmHg, p < 0,001; as pressöes do átrio esquerdo e do tronco da artéria pulmonar reduziram de 25,90 ñ 7,10 para 12,10 ñ 9,0 mmHg e de 36,47 ñ 12,93 para 24,56 ñ 9,98 mmHg, p < 0,001, respectivamente. Dos 21 casos com insucesso, em 19 ocorreram dificuldades com a técnica transeptal. Em 12, constataram-se graus distintos de derrame pericárdico, dos quais 6 exibiram sinais de tamponamento cardíaco. Os 21 casos foram operados, ocorrendo 1 óbito. O refluxo mitral aparece em 50 casos e aumentou em 8. Quinze destes casos, exibiram descompensaçäo clínica, dos quais 10 foram operados, 3 estäo sob controle clínico e 2 faleceram tardiamente. Conclusäo - A valvoplastia mitral pelo duplo cateter-baläo é técnica segura, com bons resultados, constituindo-se me procedimento terapêutico alternativo näo cirúrgico da estenose mitral


Purpose - To study the immediate clinical, echocardiographic and hemodynamic results Of 200 patients who underwent percutaneous mitral balloon valvotomy (PMV) with double balloon technique. Methods - Two hundred patients were submitted to PVM for treatment of congestive heart failure secondary to severe mitral stenosis, between August 1987 to July 1991. Their mean age was 35.2 years, and 86.5% were female patients: 81% of them was in functional class, New York Heart Association (NYHAJ III or IV; 4% was in atrial fibrilation and 4% had previous surgical commissurotomy. Results - PMV was successfully performed in 89% of the patients. The mitral valve area, by pressure half time method, increased from 0.91 ± 0.27 to 2.10 ± 0.47 cm2, p < 0.001; the mean mitral gradient decreased from 20,86 ± 6.16 to 4.26 ± 3.13 mmHg, p < 0.001; the left atrium and mean pulmonary artery pressure decreased from 22.3 ± 7.1 to 11.9 ± 8.3 and 36.47 ± 12.93 to 24.56 ± 9.98 mmHg, p < 0.001, respectively. Complications related to transeptal technique occurred in 12 patients, which resulted in cardiac tamponade in 5 and death in 1. In 19 patients the punction of the atrial septum could not be performed. Mitral regurgitation (MR) immediately after PMV appeared 1 + or more grade in 50 patients, increased in 8 patients and remained unchanged in 11 patients. Ten patients needed mitral valve replacement in the first 48h after PMV, for treatment of severe MR. Conclusion - PMV prod uces excellent immediate results and can be considered an alternative to surgery for the relief of mitral stenosis

ABSTRACT

Estudo de aspectos Doppler-ecocardiográficos em portadores de endocardite infecciosa (EI) e sua correlaçäo com prognóstico e evoluçäo. Cento e oito pacientes com suspeita de EI a fim de determinar se a presença de vegetaçäo (veg), tamanho, moblidade e local e acometimento identificam, por si só, grupos de alto risco. O diagnóstico se fez presente em 93,9% dos pacientes com EI do lado direito do coraçäo e em 77,3% daqueles com EI do lado esquerdo. Pacientes com (84,2%) e sem (15,8%) veg näo apresentaram diferença significativa na incidência de complicaçöes (embolias, ICC e óbito), o mesmo acontecendo em relaçäo ao tamanho. Pacientes com veg aórtica (Ao) apresentaram maior incidência de ICC (Ao 53,8 x Mitral (MI) 31,0% x Tricúspide (Tric0 3,7%), necessidade de cirurgia (Ao 69,2%) x Mi 34,5% x Tric 3,7%) e óbito (Ao 30,7% x Mi 13,7% x Tric 7,4%). Fenômenos embólicos foram observados em 81,4% dos pacientes com veg em Tric. Oito pacientes apresentaram EI em prótese Ao, com tratamento cirúrgico em 5 (62,5%) e óbito em 2 (25%) enquanto dentre os 12 com EI em prótese Mi, 7 (58,3%) necessitaram de cirurgia e 3 (25%) foram a óbito. Derrame pericárdico foi constatado em 51 pacientes (47,2%), ruptura de cordoalha em 14 (12,9%) e abcesso para-valvar em 6 (5,5%), os portadores deste encaminhados á cirurgia. A Doppler-ecocardiografia constitui-se método de excelência na confirmaçäo diagnóstica da EI e os aspectos por ela determinados relacionam-se, por vezes, com o prognóstico e a evoluçäo


Purpose: To study of the Doppler-echocardiographic aspects in patients with IE and its correlation with the prognosis and evolution. Patients and Methods: One hundred and eight patients with clinical of IE were prospectively studied by Doppler-echocardiography (D-E) in order to determine whether the simple presence of vegetation, its size, mobility and place of attachment could identify high risk groups. Vegetations were classified according to its size (longest axis) into small (veg < 5 mm), medium (5 mm < veg < 10 mm) and large (veg < 10 mm); according to its kind into sessible or mobile and according to its appearance into cotton like or calcifzed. Results:Patients with (84.2%) and without (15.8%) vegetations didn’t show any significant difference in the complications incidence (emboli, heart failure or death) and the same happened with its size. However, patients with aortic positioned vegetations showed ligher incidence of HF (Aortic 53.8 x Mitral 31.0% x Tricuspid 3.7%) need for surgery (Aortic 69.2% x Mitral 34.5% x Tricuspid 3.7%) and death (Aortic 30.7% x Mitral 13.7% x Tricuspid 7.4%). Emboli were observed in 81.4% of the patients with tricuspid valve vegetations. Eight patients showed IE on aortic prothesis. Five of them needed surgical treatment and 2 of them died. Among 12 patients with IE on mitral prothesis, 7 needed surgery and 3 died. Pericardial effusion were verified in 51 patients (47.2%), chordal rupture in 14 (12.8%) and valve abcess in 6 (5.5%). All patients with valve abcess were submitted to surgery. Conclusion: Doppler-echocardiography is an excellent method in the diagnosis of IE and its aspects may have, sometimes, a positive correlation with the prognosis and patient’s evolution.
