Apical ballooning syndrome (Takotsubo Syndrome): case report.

INTRODUCTION: The apical ballooning syndrome (ABS) is a single reversible cardiomyopathy often triggered by a stressful event. We aimed to present a case report regarding this disorder. CASE PRESENTATION: Here we present the case of a 77-year-old female hypertensive patient, sedentary and non-smoker, diagnosed with apical ballooning syndrome. We describe the clinical signs and symptoms, changes in markers of myocardial necrosis and changes in the electrocardiogram and coronary angiography. CONCLUSION: The course of events patient showed clinical improvement with treatment and support was not necessary to administer specific medications or interventions to reverse the situation. After hemodynamic stabilization coronary angiography showed no obstructive lesions and left ventricle with akinesia of the apex and the middle portion of the left ventricle.

Levantamento bilateral de seio maxilar utilizando biomaterial sintético associado a plasma rico em plaquetas: relato de caso clínico com análise histomorfométrica / Bilateral sinus lifting with a synthetic biomaterial associated with a platelet-rich plasma: Case report and histomorphometric analysis

O desenvolvimento de técnicas cirúrgicas e biomateriais para enxertia óssea tem levado à utilização dos mesmos nas soluções de casos complexos de reabilitação oral, onde a perda óssea está presente e necessita ser recomposta. Esses avanços têm aplicações práticas no dia a dia clínico, com elevado índice de sucesso e mínimo desconforto para o paciente. Dentre os biomateriais mais utilizados destaca-se a hidroxiapatita, que se assemelha ao osso mineral humano, é biocompatível e tem capacidade osseocondutora. O objetivo desse trabalho foi avaliar, clínica e histomorfometricamente, amostras retiradas de sítios enxertados em seios maxilares com uma nova hidroxiapatita sintética. Nesse caso relatado foi associada ao plasma rico em plaquetas (PRP).

The development of surgical techniques and biomaterials for bone grafting has led to their use in the solution of complex cases of oral rehabilitation where there is a bone loss which requires restoration. These improvements can be used in the everyday clinic, with a high success index and minimum patient discomfort. Amongst the most useful biomaterials, hydroxyapatite is outstanding not only because it is similar to the human mineral and biocompatibility, but also due to its bone conduction capacity. The objective of this paper was to evaluate from clinical and histomorphometric modes, samples collected from grafted sites in maxillary sinus with a new synthetic hydroxyapatite associated to platelet-rich plasma

Analysis of coronary vascular resistance and blood flow of venous graft in coronary artery bypass grafting.

OBJECTIVE: The aim of this study was to assess the coronary vascular resistance (CVR) and to analyze the flow differences through grafts in coronary artery bypass graft surgery. METHODS: Between 17 June and 15 July 2005, we assessed the coronary vascular resistance profile in 10 patients undergoing coronary artery bypass graft surgery by grafting a section of saphenous vein and checking CVR direct (preoperative) and indirect arterial pressure and blood flow during blood cardioplegic infusion. RESULTS: Significant differences between segments of coronary grafts with flow changes ranging from 36.52 to 100 ml/min were verified. CONCLUSION: Despite various factors that contribute to success or unsuccess of coronary grafts, the CVR preoperative assessment can be a possible method to estimate blood flow through the coronary graft implant during surgical procedure.

Análise da resistência vascular coronariana e do fluxo sanguíneo dos enxertos venosos em revascularização do miocárdio / Analysis of coronary vascular resistance and blood flow of venous graft in coronary artery bypass grafting

OBJETIVO: O trabalho tem por objetivo avaliar a resistência vascular coronariana (RVC) e analisar as diferenças de fluxo através dos enxertos em cirurgia de revascularização miocárdica. MÉTODOS: Foi avaliado o perfil da RVC em dez pacientes submetidos, entre 17 de junho e 15 de julho de 2005, a cirurgia de revascularização miocárdica com enxerto de veia safena por meio da aferição direta da pressão arterial (per-operatória) e indireta da RVC e do fluxo sanguíneo durante a infusão cardioplégica sanguínea. RESULTADOS: Foram constatadas significativas diferenças entre segmentos de enxertos coronarianos com variações de fluxo de 36,52 a 100 ml/min. CONCLUSÃO: Conclui-se, assim, que, apesar de inúmeros fatores contribuírem para o sucesso ou insucesso dos enxertos coronarianos, possivelmente pode-se compreender melhor os resultados clínicos das cirurgias por meio da interpretação adequada da RVC.

Obstrução da via de saída do ventrículo esquerdo durante ecocardiograma de estresse farmacológico - Relato de caso / Left ventricle outflow tract obstruction during pharmachological stress echocardiography - Case report

São descritas as histórias de 2 pacientes adultos encaminhados para ecocardiograma com estresse farmacológico para avaliação de dor precordial com teste ergométrico não conclusivo. Ambos apresentam prolapso da valva mitral com refluxo holossistólico discreto no ecocardiograma. Durante o estresse, quando em dose elevada de dobutamina, apresentaram movimento anterior sistólico da valva mitral com obstrução da via de saída do ventrículo esquerdo associada a dor precordial, sem alteração da contratilidade segmentar ou da função do ventrículo esquerdo. A cineangiocoronariografia dos dois pacientes demonstrou lesões coronarianas discretas, não obstrutivas.
