“…In ASD patients, tissue Doppler-derived myocardial velocities proved to be preload-dependent. 16 Jategaonkar et al showed that RV volume overload was associated with increased S values, which returned to normal after abolishment of the volume overload, whereas SR was found to be less preloaddependent. 17 Their findings represent chronic preload changes in the RV as patients were examined before and 3 months after ASD closure.…”

“…[13][14][15] Furthermore, there are limited data on the effect of loading conditions on 2D strain and SR. To date, the only accepted method able to generate load-independent parameters of ventricular function is the conductance catheter method. There have been conflicting results regarding the load sensitivity of the strain and SR of the RV when measured by Doppler 16 and speckle tracking studies. 17 The objectives of this study were to assess the effect of acute preload reduction and increased inotropy on 2D longitudinal strain and SR in patients with HLHS and relate these parameters to simultaneously derived load-independent measures of ventricular function measured by conductance catheter technique.…”

Background— Assessment of systemic right ventricular (RV) function in patients with hypoplastic left heart syndrome is important during long-term follow-up after Fontan repair. Traditional echocardiographic parameters to evaluate systolic ventricular function are affected by loading conditions. The only generally accepted load-independent parameter of systolic function, end systolic elastance ( E es ), requires invasive catheterization. Therefore, we sought to determine if parameters obtained by 2-dimensional speckle tracking (2DST) were affected by acute changes in preload and correlated with catheterization-derived indices of RV contractility in hypoplastic left heart syndrome patients after Fontan palliation. Methods and Results— Fifty-two patients with hypoplastic left heart syndrome (median age, 6.6; range 2.9–22.2 years) were prospectively enrolled to have echocardiography and conductance catheter studies performed simultaneously. We compared traditional echo, 2-dimensional speckle tracking and catheterization-derived parameters during different states of preload at baseline and during dobutamine infusion. Global longitudinal strain (S) showed a tendency to decrease with preload reduction, whereas global longitudinal strain rate (SR) did not change (S: −17.7±3.4% versus −16.9±3.8%, P =0.08; SR: −1.30±0.29 versus −1.34±0.34 s −1 , P =0.3). S did not change with dobutamine infusion (−17.7±3.4% versus −18.4±3.9%, P =0.24), whereas SR increased significantly (−1.30±0.29 versus −2.26±0.49 s −1 , P <0.001). RV E es correlated with SR ( r s = −0.47, P <0.001), but not with S ( r s =0.07, P =0.5) or other echocardiographic parameters. Conclusions— In contrast to S, SR was not affected by preload and correlated with E es of the systemic RV. SR may be a useful noninvasive surrogate of RV contractility and suitable for follow-up of patients with hypoplastic left heart syndrome after Fontan palliation.

“…Está bem demonstrado que o remodelamento precoce ocorre nos primeiros dias após o fechamento percutâneo do defeito, com quedas drásticas no tamanho do ventrículo direito mensuradas através do modo-M ou estimativa do volume ventricular, tanto em crianças como em adultos. [44][45][46][47] Essas alterações atingem valores dentro da normalidade na maioria dos pacientes em até um mês após o procedimento percutâneo. 48 Entretanto, séries de pacientes submetidos a reparo cirúrgico são controversas quanto a esse processo, mesmo após alguns anos do procedimento.…”

A comunicação interatrial (CIA) é uma das malformações congênitas mais frequentes, representando aproximadamente 5% a 10% de todos os defeitos cardíacos congêni-tos. O tipo mais comum é a CIA ostium secundum (CIA OS), que representa cerca de 75% dessas malformações. Quando descoberta tardiamente ou na ausência de tratamento, além da alteração no exame clínico, pode existir insuficiên-cia cardíaca, arritmias cardíacas, insuficiência mitral, sobrecarga ventricular direita e hipertensão pulmonar. Em casos avançados com hipertensão pulmonar grave e reversão do shunt interatrial (direita para esquerda) instala-se a cianose, o que indica doença cardiopulmonar grave e mortalidade aumentada. Nas últimas décadas, com o aprimoramento das técnicas e dos dispositivos percutâneos, as possibilidades de tratamento dos defeitos congênitos por via percutânea têm crescido vertiginosamente. Vários estudos já demonstraram os excelentes resultados imediatos e a longo prazo da atriosseptoplastia percutânea. Além de proporcionar maior conforto ao paciente, menores taxas de complicações, menor tempo de recuperação intra e extra-hospitalar e eficácia similar à da atriosseptoplastia cirúrgica, em países desenvolvidos, é comprovadamente a opção mais econômica. Não há dúvidas de que, em futuro próximo, a relação custoefetividade desse procedimento será observada também em países em desenvolvimento como o Brasil, em que o custo da prótese, ainda hoje, é o principal obstáculo para a padronização desse procedimento, e em que os valores pagos pelos procedimentos cirúrgicos continuam muito defasados. DESCRITORES:Comunicação interatrial. Cardiopatias congênitas. Próteses e implantes. ABSTRACT Percutaneous Closure of Atrial Septal Defects by the Brazilian Health System: an Economically Feasible OptionAtrial septal defect (ASD) is one of the most frequent congenital malformations, representing 5% to 10% of all congenital heart defects. The most common type is the ostium secundum ASD (OS ASD), and represents 75% of these malformations. When diagnosed late or left untreated, in addition to abnormalities in the clinical examination, there may be heart failure, cardiac arrhythmias, mitral insufficiency, right ventricular overload and pulmonary hypertension. In advanced cases with severe pulmonary hypertension and interatrial shunt reversal (right to left), there is cyanosis, which indicates severe cardiopulmonary disease and increased mortality. In the last decades, with the improvement of percutaneous techniques and devices, the possibility of percutaneous treatment of congenital defects has increased dramatically. Several studies have shown excellent early and long-term results of percutaneous atrial septoplasty. In addition to providing greater comfort for patients, lower complication rates, less in-hospital and extra-hospital recovery time and efficacy similar to that of surgical atrial septoplasty in developed countries, it is definitely the most economic option. There is no doubt that in the near future, the cost-effectiveness ratio of this proc...

“…It is deserving of note that echocardiography is deemed an inaccurate tool for the quantitative assessment of the RV function because of a lack of an ideal geometric model for the evaluation of ventricular volumes (22,23).The major potential advantages of strain and SR imaging for the assessment of the RV function are the independence of geometric assumptions and endocardial border tracing. In addition, both strain and SR images are feasible in the majority of patients (even in the presence of low-quality 2-D imaging), reproducible, and relatively load and rate independent (24)(25)(26). Both techniques also permit the quantification of the longitudinal systolic function for each RV segment separately.…”

Original Investigation Özgün Araşt›rma 536ÖZET Amaç: Fallot tetralojisi (TOF) siyanotik konjenital kalp hastalığının en sık görülen şeklidir. Günümüzde, TOF onarımı sonrası rezidüel pulmoner yetersizliği (PR) olan hastaların sayılarında artış ile karşı karşıyayız. Sağ ventrikül (RV) hacim ve fonksiyonu klinik karar vermeyi etkileyen en önemli faktörler arasındadır. Kardiyak manyetik rezonans (CMR) RV fonksiyonunun nicel değerlendirilmesi için altın standart yöntemdir; ancak, rutin klinik takip için pahalıdır ve bazen kontrendikedir. Biz TOF onarımı yapılan hastalarda CMR ile RV sistolik fonksiyonu değerlendirmesini Doppler kaynaklı strain (S) ve strain rate (SR) görüntülemesi ile karşılaştırmaya çalıştık. Yöntemler: Kesitsel bir çalışmada, TOF onarımından epey sonra şiddetli PR'li 70 hasta (22 kadın, ortalama yaş=22±4,9) değerlendirildi. RV serbest duvarının bazal, mid ve apikal segmentlerinde peak sistolik strain ve SR ölçülerek kısa-aks sine MR da ölçülen RV fonksiyonu ile karşılaştırıldı. RVEF ve S/SR arasındaki ilişkiler sıra lojistik regresyon modelleri ile incelendi.
