چکیده
s d M m r t p Os avanços na terapêutica percutânea das cardiopatias estruturais e das arritmias conduziram ao desenvolvimento de novos métodos de imagem, não invasiva e invasiva, para responder às necessidades de diagnóstico, planificação e monitorização dos procedimentos1,2. Neste contexto, e dependendo do tipo de patologia a tratar e da intervenção planeada, existem múltiplos métodos ao nosso dispor, desde a ecocardiografia transtorácica e transesofágica à intracardíaca, passando pela angioTC e pela ressonância magnética nuclear. O controlo radioscópico revela várias insuficiências e desvantagens, nomeadamente a ausência de resolução para o estudo dos tecidos moles, o uso de doses acrescidas de radiação e a necessidade de utilização de contraste. No entanto, qualquer método de imagem que se adicione a um procedimento de intervenção percutâneo representa um custo acrescido em relação à utilização da radioscopia. Idealmente, um método de imagem a utilizar no Laboratório de Hemodinâmica ou de Eletrofisiologia deverá preencher vários critérios: facilidade de utilização, imagem em tempo real e tri/quadri-dimensional, visualização próxima das estruturas cardíacas e do material utilizado sem interferência com o próprio procedimento, invasibilidade mínima, custo reduzido, ausência de necessidade de

Intracardiac Thrombosis in Sickle Cell Disease
In patients with sickle cell disease, thrombotic microangiopathy is a rare complication. Also in sickle cell disease, intracardiac thrombus formation without structural heart diseases or atrial arrhythmias is a rare phenomenon. We herein describe a 22-year-old woman, who was a known case of sickle cell-βthalassemia, had a history of recent missed abortion, and was admitted with a vaso-occlusive...
متن کاملRecent advances in echocardiography for valvular heart disease
Echocardiography is the imaging modality of choice for the assessment of patients with valvular heart disease. Echocardiographic advancements may have particular impact on the assessment and management of patients with valvular heart disease. This review will summarize the current literature on advancements, such as three-dimensional echocardiography, strain imaging, intracardiac echocardiograp...
متن کاملWhy is intracardiac echocardiography helpful? Benefits, costs, and how to learn
Current interventional procedures in structural heart disease and cardiac arrhythmias require peri-interventional echocardiographic monitoring and guidance to become as safe, expedient, and well-tolerated for patients as possible. Intracardiac echocardiography (ICE) complements and has in part replaced transoesophageal echocardiography (TEE), including real-time three-dimensional (RT-3D) imagin...
متن کاملThe present and future of intracardiac echocardiography for guiding structural heart disease interventions.
Novel transcatheter therapies for the treatment of valvular and congenital heart disease have increased exponentially in recent years. Parallel to this trend has been the need for multi-modality imaging in the planning, guidance, and evaluation of procedurerelated outcomes and complications. Echocardiography has played a pivotal role within the cardiac catheterization laboratory. Periprocedural...
متن کاملCurrent Clinical Application of Intracardiac Flow Analysis Using Echocardiography
In evaluating the cardiac function, it is important to have a comprehensive assessment of structural factors, such as the myocardial or valvular function and intracardiac flow dynamics that pass the heart. Vortex flow that form during left ventricular filling have specific geometry and anatomical location that are critical determinants of directed blood flow during ejection. The formation of ab...
متن کاملAtrial Fibrillation Ablation in Adults With Repaired Congenital Heart Disease.
The incidence of atrial fibrillation (AF) in congenital heart disease (CHD) adults has increased in the past decades due to a longer life expectancy of this population where the subjects are exposed to cardiac overflow, overpressure and structural changes for years. The literature regarding AF ablation in repaired CHD adults emphasizes the importance of intracardiac echocardiography (ICE) to pe...
