ABSTRACT

PURPOSE--To report the experience in the treatment and long-term follow-up of patients with renovascular hypertension submitted to angioplasty and/or surgical revascularization, and to compare blood pressure and renal function responses to both treatment. METHODS--One hundred and twenty-four patients diagnosed with renovascular hypertension, divided, according to the etiology, as atherosclerosis (76 patients), fibromuscular dysplasia (32) and arteritis (16), were submitted to isolated or associated treatment of renal revascularization by percutaneous transluminal angioplasty (71 patients) or surgery (84). The patients were followed-up during 2.5 +/- 1.5 years and we evaluate blood pressure response and renal function preservation. In relation to blood pressure control, the patients were considered as cured when normotensives without antihypertensives, improved when normotensives with fewer drugs than previously, and unchanged, when out of these criteria. RESULTS--From 124 patients, 20 per cent were considered cured, 54 per cent improved and 26 per cent unchanged, after a mean follow-up of 2.5 +/- 1.5 years. Patients with atherosclerosis and fibromuscular dysplasia presented a higher rate of care and improvement after surgery. The blood pressure and the number of antihypertensive drugs decreased significantly during the follow-up among patients that cured or improved arterial hypertension, either after angioplasty (190 +/- 26/115 +/- 14 mmHg vs 130 +/- 34/85 +/- 7 mmHg. 2.70 vs 1.60 drugs) or after surgery (194 +/- 17/115 +/- 16 mmHg vs 143 +/- 18 mmHg vs 88 +/- 8 mmHg, 1.88 vs 1.51 drugs). It was also observed a significant decrease of serum creatinine among these patients. CONCLUSION--Renal revascularization in patients with renovascular hypertension, either by angioplasty or surgery, is beneficial to control blood pressure and to preserve renal function in the majority of patients

ABSTRACT

O presente estudo tem por finalidade analisar tardiamente o padrao anatômico evolutivo das artérias coronárias do coraçao transplantado. Para cumprir tal proposiçao foram selecionados 22 pacientes submetidos ao transplante cardíaco ortotópico, com seguimento pós-operatório superior a 36 meses. As variáveis eleitas para este fim foram aferidas anualmente até o quinto ano de pós-operatório. A análise da ventriculografia mostrou a estabilidade da fraçao de ejeçao (p=O,99) em valores normais. A cineangiocoronariografia seqüencial evidenciou incidência crescente de lesoes arteriais com comprometimento da funçao contrátii. As lesoes obstrutivas acometeram as artérias coronárias difusamente, com predomínio no território distal. Os episódios de rejeiçao aguda e a etiologia da cardiomiopatia nao modificaram a evoluçao natural da aterosclerose coronária.

ABSTRACT

Objetivo - Avaliar os resultados da valvoplastia mitral por cateter baläo (VMCB) a curto e a médio prazos. Métodos - Cento e quatro procedimentos em 103 pacientes, 89 (87%) mulheres e média etária de 33 anos. O diagnóstico foi estenose mitral (EM) em 95 (91%), reestenose mitral em 7 (7%) e bioprótese estenótica em 2(2%). Doze pacientes (10%) estavam em classe funcional (CF) II (NYHA), 73 (70%) em CF III e 19 (18%) em CF IV. Noventa e três (89%) estavam em ritmo sinusal, 10 (10%) em fibrilaçäo atrial e 1 (1%) em ritmo funcional. Em 99% dos casos a técnica empregada foi transeptal. Resultados hemodinâmicos comparativos entre pré X pós VMCB imediato foram: área valvar mitral (cm2) 0,75 ñ 0,27 x 1,68 ñ 0m48 (p < 0,0001), gradiente AE-VE médio (mmHg) 19,52 ñ 8,03 x 5,44 ñ 4,38 p < 0,0001); pressäo média de AE (mmHg) 24,72 ñ 8,76 x 9,63 ñ 6,11 (p < 0,0001); índice cardíaco (L/min/m*) 2,55 ñ 0,69 x 2,92 ñ 0,77 (p < 0,0001); pressäo média de AP (mmHg) 40,17 ñ 16,52 x 25,65 ñ 13,77 (p < 0,0001). Ao ecocardiograma os resultados comparativos entre pré-VMCB, pós-VMCB, controle de 6 meses e 12 meses pós-VMCB foram respectivamente: área valvar mitral (cm*) 0,89 ñ 0,23 x 1,87 ñ 0,41 x 1,72 ñ 0,43 x 1,64 ñ 0,44 e gradiente transvalvar mitral (mmHg) 13,12 ñ 4,66 x 6,44 ñ 2,93 x 7,72 ñ 3,24 x 8,30 ñ 4,17. Houve um óbito imediato pós-VMCB em paciente portadora de tromboembolismo pulmonar, 4 (4%) pacientes com insuficiência mitral importante (1 óbito no pós-operatório imediato) e 2 pacientes com reestenose mitral. Conclusäo - A VMCB mostra-se método eficaz e seguro ocorrendo persistência de bons resultados no período de 1 ano de acompanhamento


Purpose - To evaluate percutaneous mitral balloon valvuloplasty (PMBV) results immediately and one yearfollow-up. Methods - One hundred andfour procedures in 103 patients, 89 (87%) were women and mean age was 33. Ninety five (91%) had mitral stenosis, 7 (7%) mitral restenosis and 2 (2%) stenotic bioprosthesis. Twelve (10%) patients were in functional class (FC) II (NYHA), 73 (70%) in FC III and 19 (18%) in FC IV. Ninety three (89%) were in sinusal rhythm, 10 (10%) had atrialfibrilation and 1 (1%) junctional rhythm. In 99% cases the transeptal access was used. Results - The comparative haemodinamic results late x immediately after-PMBV were mitral valve area (cm2) 0.75 ± 0.27 x 1.68 ±0.48 (p < 0.0001), gradiente AE-VE average (mmHg) 19.52 ± 8.03 x 5.44 ± 4.38 (p < 0.0001); average pressure AE (mmHg) 24.72 ± 8.76 x 9.63 ± 6.11 (p < 0.0001), cardiac inde x (L/ min/m2) 2.55 ± 0.69 x 2.92 ± 0.77 (p < 0.0001); average pressure PA (mmHg) 40.17 ± 16.52 x 25.65 ± 13.77 (p < 0.0001). The echocardiography results pré-PMBV, post-PMBV, 6 and 12 months after PMBV were respectively: mitral valve area (cm2) 0.89 ± 0.23 x 1.87 ± 0.41 x 1.72 ± 0.43 x 1.64 ± 0.44 and mitral transvalvar gradient (mmHg) 13.12 ± 4.66 x 6.44 ± 2.93 x 7.72 ± 3.24 x 8.30 ± 4.17. There was one death immediately after-PMBV in a patient with pulmonar thromboembolism. Four (4%) had severe mitral regurgitation and went to surgery (1 death). There were 2 mitral reestenosis. Conclusion - For selected patients PMBVis a safe method and the good results are maintained in 1 year follow-up

ABSTRACT

Purpose­To evaluate the evolution of patients with critical aortic stenosis (AS) submitted to balloon aortic valvuloplasty (BAV). Patients and Methods­sixteen patients (mean age 74.0 ± 5.1 years), 11 (68.7%) women. The study periods consisted during the 3 rd (post-1) and 15th month (post-2) after dilatation. Results­The functional class of angina and dyspnea persisted in all patients during period post-1, in 75% of theo patients, during period post-2 in relation to intra-hospital evaluation. However, in period post-1, 53% of the patients had significant reduction of aortic valve area, trend which remained in period post-2. Simultaneously, progressive (insignificant) elevation of the left ventricular aortic peak to peak gradient was noticed in the periods post-1 and post-2. Two deaths and two aortic valve replacements occurred during the study. Conclusion­BAV is associated to maintenance of functional class improvement obtained immediatly after dilatation despite the aortic valve restenosis registered by echodopplercardiography

ABSTRACT

A angioplastia transluminal coronária näo é conduta habitual na fase aguda do miocárdio por oclusäo de tronco de coronária esquerda. Aplicamos esta terapêutica em dois casos: o primeiro, homem de 54 anos, foi submetido a desobstruçäo mecânica e angioplastia de tronco de coronária esquerda, após 145 minutos do início dos sintomas, bem como a cirurgia de revascularizaçäo do miocárdio doze horas mais tarde; o segundo, mulher de 77 anos, foi submetida aos dois primeiros procedimentos, nnäo sendo porém operada. No primeiro caso houve boa evoluçäo imediata e tardia, no segundo, a paciente faleceu doze horas após


Percutaneous transluminal coronary angioplastg is unusual in acute myocardial infarction after left main coronary artery occlusion. We applied this therapy in two cases. The first, a 54-year-old man, submitted to mechanical reperfusion and left main coronary artery angioplasty 145 minutes after the beginning of the symptoms and coronary artery surgery 12 hours later; the second, a 77-year-old woman, submitted to both procedures but not to surgery. In the first case there was a satisfactory follow-up but in the second, the patient died twelve hours later

ABSTRACT

A angioplastia transluminal por cater-baläo tem sido utilizada de maneira promissora no tratamento de diversas cardiopatias congênitas, especialmente na estenose pulmonar valvar. Descrevemos o caso de um lactente de 3 meses de idade com diagnóstico de drenagem anômala total de veias pulmonares (DATVP) em veia cava superior direita revelando obstruçäo na sua desembocadura. Foi submetida à dilataçäo da obstruçäo utilizando-se dois cateteres-baläo de 4mm de diâmetro (Simpson Ultra Low Profile), com evidências manométricas, agngiográficas e clínicas de bom resultado do procedimento. A pressäo sistólica do ventrículo direito diminuiu de 68 par 49 mmHg e a pressäo média da veia pulmonar comum de 41 para 17 mmHg. Houve melhora evidente da cianose e dos sinais congestivos. Embora seja uma experiência isolada no Srviço, os autores sugerem que a angioplastia transluminal por cateter-baläo possa ser opçäo terapêutica inicial em crianças com DATVP na forma obstrutiva, consideradas de alto risco para correçäo cirúrgica

ABSTRACT

Ocorreu fragmentaçäo de cateter de Sylastic posicionado ao nível da veia cava inferior, por ocasiäo de sua retirada em uma criança de 11 meses de idade. Visando sua extraçäo percutânea, procedeu-se a introduçäo de "grasping forceps". Näo sendo o cateter radiopaco, o posicionamento do fragmento, na junçäo da veia cava inferior com o átrio direito, foi determinado pela ecocardiografia. Os movimentos para apreensäo do fragmento foram controlados simultaneamente pela radioscopia (imagem do forceps) e pela ecocardiografia (imagem do fragmento do cateter). Após ter se conseguido a pega, retirou-se o fragmento, intacto, através da veia cava inferior. A associaçäo dos dois métodos de imagem abre novas possibilidades terapêuticas, contribuindo para evitar intervençöes cirúrgicas em situaçöes de fragmentaçäo intravascular de cateter näo radiopaco
