"The main target of clinical and academic cardiology activities is to optimize the patient's management and ultimately their welfare. Professionals manage patients according to their own understanding of disease process; clinicians concentrate on alleviating the symptoms and echocardiographers on identifying the disease. This book helps to 'cross the barrier' and describes the common ground between physiologic disturbances and their management which should ideally form the shared basis for understanding and managing all cardiac problems.A practical review of the many uses of echocardiography in clinical practice, Clinical Echocardiography is designed to integrate and refine the investigation of cardiac disorders within the framework of the pathologic, physiologic and surgical appearances of heart disease. It has been common to consider echocardiographic findings separately from the more physical aspects of heart disease. However, with the development of new imaging modalities such as three- and four-dimensional echocardiography, it has become necessary to consider this imaging as a window on the heart. "

"ABSTRACTAtrial septal defect is one of the most common forms of congenital heart disease. Although various M-mode and two-dimensional echocardiographic characteristics of atrial septal defect have been described, these criteria lack sensitivity and specificity. By allowing visualization of blood flow, the demonstration of right-toleft or left-to-right shunting is possible with contrast echocardiography(11-16). The purpose of the first part of this study was to verify the utility of this technique for evaluating patients with atrial septal defect.We observed that contrast echocardiographic shunts may persist long after closure of an atrial septal defect. The aim of the second part of' this study was to determine whether this indicates unsuccessful repair or a hemodynamically important residual shunt.Peripheral venous injection of echocardiographic contrast allows the visualization of blood flow through the right sided cardiac cavities. The purpose of the third part of the study was to determine whether the technique may aid to the diagnosis of some right heart abnormalities by the demonstration of specific blood flow patterns.The patterns of echo contrast appearance in the inferior vena cava after upper extremity injection may be related to right heart hemodynamics(17,18). The purpose of the fourth part of the study was to determine the utility of contrast echocardiography of the inferior vena cava for the assessment of right heart hemodynamics. Since the technique can be used to detect tricuspid regurgitation( 9-21), we also studied whether estimation of its severity is possible,. because this would have important therapeutic and prognostic implications.An intriguing potential .future application of contrast echocardiography is the study of myocardial perfusion. The technique would offer many advantages over the other imaging modalities such as radionuclide techniques, contrast-enhanced computerized transmission tomography, positron emission tomography and nuclear magnetic resonance. Contrast echocardiographic. myocardial perfusion imaging would have a good spatial and temporal resolution and allows direct and simultaneous assessment of both the perfusion and function of the myocardium. It is also much less expensive. However, a good and safe echocardiographic contrast agent for such application in humans is not yet available. "

"Latar Belakang: Keparahan stenosis pada penyakit jantung koroner (PJK) stabil berkaitan erat dengan prognosis. Dalam memprediksi keparahan stenosis dapat digunakan beberapa faktor klinis dan ekokardiografi. Akhir-akhir ini berkembang speckle tracking echocardiography yang mampu menilai strain miokardium dan baik untuk memprediksi stenosis. Penilaian faktor-faktor klinis dan ekokardiografi strain bersama-sama diharapkan mampu memprediksi lebih baik keparahan stenosis. Tujuan: Mengetahui apakah faktor-faktor klinis (usia, jenis kelamin, diabetes, angina tipikal, riwayat infark) dan global longitudinal strain (GLS) pada ekokardiografi strain dapat memprediksi keparahan stenosis pasien PJK stabil yang dinilai dengan skor Gensini. Membuat model prediktor dari parameter yang bermakna. Metode: Studi potong lintang dilakukan di RSCM pada periode Maret-Mei 2019. Pengambilan sampel secara konsekutif pada pasien PJK stabil yang menjalani angiografi koroner. Analisis bivariat dilakukan dengan chi-square, dilanjutkan analisis multivariat dengan regresi logistik metode baickward stepwise pada variabel yang bermakna. Hasil: Terdapat 93 subjek yang masuk dalam penelitian. Pada analisis bivariat faktor-faktor prediktor yang bermakna adalah diabetes melitus (OR 2,79; IK95%:1,08-7,23), riwayat infark (OR 4,04; IK95%:1,51-10,80), angina tipikal (OR 5,01; IK95%:1,91-13,14), dan GLS ≥-18,8 (OR 30,51; IK95%:10,38-89,72). Pada analisis multivariat faktor-faktor prediktor yang bermakna adalah angina tipikal (OR 4,48; IK95%:1,39-14,47) dan GLS ≥18,8 (OR 17,30; IK95%:5,38- 55,66). Tidak dilakukan pembuatan model prediktor karena hanya 2 faktor prediktor yang bermakna. Simpulan: Angina tipikal dan GLS merupakan faktor-faktor prediktor keparahan stenosis pada pasien PJK stabil, sedangkan faktor usia, jenis kelamin, diabetes, dan riwayat infark bukan merupakan prediktor keparahan stenosis pasien PJK stabil. Model skor prediktor tidak dikembangkan karena hanya 2 faktor prediktor yang bermakna.

Background: In patient with stable coronary artery disease (CAD), severity of stenosis is closely related to prognosis. It is known that several clinical and echocardiographic parameters can predict severity of stenosis. Recently a new method in echocardiography called speckle tracking echocardiography can be used to asses myocardial strain, which is a good predictor of stenosis severity. Assessment of clinical parameters together with strain echocardiography parameter is expected to make better prediction. Objective: To determine whether clinical factors, i.e. age, sex, diabetes, typical angina, and history of myocardial infarction, and strain echocardiography parameter, i.e. global longitudinal strain, can predict severity of coronary artery stenosis measured with Gensini score. To further develop a prediction model based on significant parameters. Methods: This is a cross-sectional study taken at Cipto Mangunkusumo Hospital during period March-May 2019. Patient with stable CAD scheduled to undergo coronary angiography is recruited consecutively. Bivariate analysis using chi- square is performed to each predictor. Significant predictors are further analysed using backward stepwise logistic regression. Results: The study group include 93 subjects. Significant predictors on bivariate analysis include diabetes melitus (OR 2.79; CI95%:1.08-7.23), history of myocardial infartion (OR 4.04; CI95%:1.51-10.80), typical angina (OR 5.01; CI95%:1.91-13.14), and GLS ≥-18.8 (OR 30.51; CI95%:10.38-89.72). Significant predictors on multivariate analysis are typical angina (OR 4.48; CI95%:1.39-14.47) and GLS ≥18.8 (OR 17.30; CI95%:5.38-55.66). Predicton model is not developed because there are only two significant predictors. Conclusions: Typical angina and GLS are predictors of stenosis severity in patient with stable CAD. Age, sex, diabetes, and history of myocardial infarction are not significant predictors. A prediction model can not developed because there are only 2 significant predictors."

"Latar Belakang : Infeksi COVID-19 dewasa ini telah diketahui memiliki implikasi jangka panjang meski periode akut telah tertangani, suatu fenomena yang dinamakan long COVID syndrome atau sindrom pasca COVID-19. Patofisiologi dari kejadian ini masih belum diketahui dengan jelas. Studi melaporkan bahwa sindrom pasca COVID-19 melibatkan beberapa organ, diantaranya adalah sistem kardiovaskular. Pemeriksaan nilai LV GLS dan RV LS pada ekokardiografi dinilai akurat dalam mendeteksi disfungsi miokard dan fibrosis endomiokardial. Selain itu, hingga saat ini, data mengenai faktor-faktor saat admisi sebagai prediktor terhadap kejadian sindrom pasca COVID-19 masih terbatas. Tujuan : Mengetahui nilai parameter ekokardiografi LV GLS dan RV LS sebagai penanda disfungsi miokard dan fibrosis jantung serta mengidentifikasi faktor-faktor saat admisi yang berpengaruh terhadap kejadian sindrom pasca COVID-19.Metode : Penelitian ini adalah deskriptif-analisis menggunakan metode potong lintang. Pemilihan subjek dilakukan dengan metode consecutive sampling. Pemeriksaan ekokardiografi termasuk pemeriksaan global longitudinal strain (GLS) dilakukan oleh dua orang observer 4 bulan pasca perawatan rumah sakit. Selanjutnya, analisis multivariat berupa regresi linear dilakukan untuk mengetahui faktor admisi yang berpengaruh terhadap perbedaan nilai GLS pada kelompok penelitian. Hasil : 100 subjek dengan komorbiditas kardiovaskular dan riwayat COVID-19 memenuhi kriteria dan syarat penelitian. Ditemukan nilai penurunan nilai LV-GLS pada kelompok ini. Subjek dengan komorbiditas kardiovaskular tanpa riwayat COVID-19 (n=31, kontrol 1) yang telah melalui proses matching berdasarkan usia, gender, dan faktor resiko, serta subjek sehat (n-31, kontrol 2) sebagai pembanding validitas GLS. Terdapat perbedaan signifikan rerata nilai LV GLS antar 3 kelompok (p<0.05, rerata ±SB -16.17 ± 3.379, -19.48 ± 1.141, -21.48 ± 1.777 berturut-turut untuk kelompok kasus, kontrol 1, kontrol 2), dengan nilai paling rendah pada kelompok kasus. Faktor saat admisi yaitu status CAD memiliki hubungan yang signifikan (p 0.038) dengan penurunan LV GLS pada pasien post covid-19 dengan komorbid kardiovaskular. Kesimpulan : Terdapat penurunan nilai LV GLS yang signifikan pada sindrom pasca COVID-19 disertai komorbiditas kardiovaskular. CAD merupakan prediktor penurunan fungsi maupun fibrosis jantung sebagai manifestasi sindrom pasca COVID-19.

Background : Recently, COVID-19 infection has been known to have a longer implication, even after the initial acute phase has been managed, a phenomenon termed as long COVID syndrome or “sindroma pasca COVID-19”. The exact pathophysiological mechanism of this event is still unknown. Previous studies reported that long COVID syndrome involves multiple organs, one of which is the cardiovascular system. Measurement of echocardiography LV GLS and RV LS values are reported to be accurate to detect myocardial dysfunction and endomyocardial fibrosis. Moreover, up until now, data regarding admission factors as predictors for long COVID syndrome incidences are still limited.

Objective : Assessing echocardiography LV GLS and RV LS values as a marker for myocardial dysfunction and heart fibrosis and identifying admission factors which may predict the incidence of long COVID syndrome

Methods : This is an observational study with a cross-sectional using a consecutive sampling method. Echocardiography including global longitudinal strain (GLS) measurement was done by two examiners 3 months after initial hospitalization. Multivariate analysis linear regression was subsequently used to investigate admission factors which are associated with differences in GLS measurement.

Results : Total of 100 subjects with cardiovascular comorbidities and prior COVID-19 infection were enrolled. Echocardiography examination showed lower GLS values in this group compared to the normal population. Age, sex and risk factors-matched subjects with cardiovascular comorbidity without a history of COVID-19 (n=31, Control 1) and healthy subjects (n-31, Control 2) were subsequently used as comparisons to validate GLS results. There were significant differences in LV-GLS levels between the three groups, with the lowest values measured in the case group (p<0.05, mean ±SD -16.17 ± 3.379, -19.48 ± 1.141, -21.48 ± 1.777 respectively for case, control 1, and control 2 groups). A history of coronary artery disease upon admission was found to be associated with decreased LV GLS values in recovered COVID-19 patients with cardiovascular comorbidity.

Conclusion : LV GLS values significantly decrease in long COVID syndrome with cardiovascular comorbidities. Having a previous history of CAD upon admission may serve as predictors of deteriorated functions or heart fibrosis as manifestations of long COVID syndrome. "
