"La disponibilità e la diffusione di tecnologie performanti ha determinato l’affermarsi degli studi angio-TC ed angio-RM come tecniche semplici ed affidabili per la caratterizzazione ed il planning terapeutico delle principali patologie del sistema cardiocircolatorio, la cui conoscenza è divenuta ormai obbligatoria per tutti i radiologi. Lo scopo di questo testo è di fornire indicazioni tecniche in forma sintetica, ma quanto più possibile completa, relativamente ai principi tecnici ed alla metodologia d’esame per studi angio-TC ed angio-RM di alta qualità negli scenari clinici più vari, presentando allo stesso tempo un’ampia casistica di supporto, ricca di spunti interpretativi e di suggerimenti pratici per la valutazione e la refertazione degli esami. Lo scopo del testo sarà anche di dimostrare i vantaggi ed i limiti delle due metodiche a confronto nelle diverse patologie e nei diversi distretti vascolari, in modo da fornire indicazioni al radiologo esperto ed a quello in formazione."

"La cardio-TC è un esame non invasivo del cuore e delle coronarie che sta entrando sempre più frequentemente negli algoritmi diagnostici delle patologie cardiache, con un ruolo complementare rispetto alla coronarografia convenzionale: la cardio-TC permette infatti di valutare direttamente la parete delle coronarie, rendendo possibile uno studio morfologico delle placche aterosclerotiche, al quale è inoltre possibile affiancare la valutazione funzionale della cinesi delle camere e delle valvole cardiache, arricchendo ulteriormente il valore diagnostico dell’indagine. Per utilizzare al meglio tutte le possibilità offerte dalla tecnologia è importante che il Radiologo sia opportunamente formato, con approfondite competenze di diagnostica per immagini, e che sia in grado di interagire pariteticamente con il Clinico. Uno studio Cardio-TC di alta qualità richiede aggiornamenti in merito a tecnologia, protocolli di studio e modalità di analisi delle immagini, oltre al riconoscimento dell’appropriatezza delle indicazioni all’esame e conoscenze di fisio-patologia cardiaca e cardio-farmacologia. "

"Il recente sviluppo tecnologico degli scanner TC e dei sistemi di visualizzazione delle immagini ha consentito un imponente ingresso della tecnica di angio-TC nella pratica clinico-diagnostica, conferendole un ruolo di primo piano sia nello studio in elezione che in situazioni di urgenza/emergenza, grazie ad immagini di qualità ottimale e di facile interpretazione. Il presente volume intende offrire un’introduzione alle tecniche di imaging vascolare con la massima semplicità e praticità possibili, cercando di riportare in maniera esaustiva le basi della tecnica d’esame, le principali patologie riscontrabili nella pratica clinica e i quadri normali e patologici da riconoscere nello studio post-operatorio.

"Latar Belakang: Telah diketahui infeksi COVID-19 dapat menetap menjadi sindroma pasca COVID-19. Magnetic Resonance Imaging (MRI) kardiak memiliki nilai diagnostik tinggi untuk menilai karakteristik jaringan miokard. Belum diketahui secara pasti efek jangka panjang COVID-19 terhadap jaringan miokardium serta faktor-faktor admisi yang memiliki pengaruh terhadap prevalensi sindroma pasca-COVID-19 pada populasi dengan penyakit kardiovaskular. Tujuan: Mengevaluasi prevalensi fibrosis miokardium dengan MRI kardiak pada pasien dengan penyakit kardiovaskular dan riwayat COVID-19 1 tahun pascaperawatan, serta mengidentifikasi faktor admisi yang berpengaruh terhadap fibrosis miokardium. Metode: Kohort prospektif dengan menilai parameter MRI kardiak pada pasien terkonfirmasi COVID-19 dengan penyakit kardiovaskular 1 tahun pascaperawatan. Selanjutnya, dilakukan analisa temuan MRI kardiak terhadap kelompok kontrol tanpa riwayat COVID-19 yang telah di-matching berdasarkan umur, jenis kelamin, dan faktor resiko. Analisa multivariat dilakukan untuk mengetahui faktor admisi yang memiliki hubungan dengan kejadian fibrosis miokardium. Hasil: Total 32 subjek dengan penyakit KV dan riwayat COVID-19 1 tahun pascaperawatan dengan 49 subjek kontrol disertakan dalam studi ini. Terdapat peningkatan yang signifikan pada parameter MRI kardiak yaitu proporsi abnormal T1 relaxation time (65,5% vs 36,7%; p-value=0,011) serta late gadolinum enhancement (LGE) skar noniskemik 62,5% vs 29,8%;p-value=<0,001) pada kelompok dengan riwayat COVID-19 dibanding kontrol. Tidak ditemukan faktor admisi yang berpengaruh terhadap peningkatan LGE noniskemik/T1 abnormal. Kesimpulan: Terdapat peningkatan prevalensi fibrosis miokardium pada pasien dengan penyakit KV dan riwayat COVID-19 1 tahun pascaperawatan dibanding kontrol dinilai melalui MRI kardiak. Tidak terdapat hubungan antara faktor admisi dengan fibrosis miokardium 1 tahun pascaperawatan COVID-19.

Background: Presently, it has been acknowledged that COVID-19 infection may persist longer as Post-acute COVID-19 Syndrome. Cardiac Magnetic Resonance Imaging (cMRI) possesses a high diagnostic value to evaluate myocardial tissue characteristics. Data are still limited regarding longer implications of COVID-19 infection towards myocardial tissues and predictive admission factors in patients with Cardiovascular Diseases (CVD).

Aim(s): To evaluate the prevalences of myocardial fibrosis using cMRI in patients with CVD and one year post-COVID-19 hospitalization and identifying admission factors in correlation with myocardial fibrosis. 

Method(s): Prospective cohort to assess cMRI parameters in patients with CVD and history of COVID-19 one year post-hospitalization. The results were then compared with the age-, sex-, risk factors-matched control group without prior of COVID-19 infection. Lastly, multivariat analysis was done to identify relations between admission factors and myocardial fibrosis. 

Result(s): A total of 32 subjects with CVD one year post-COVID-19 hospitalization and 49 controls were included in this study. Significant increases of cMRI parameters, namely abnormal T1 relaxation time (65.5% vs 36.7%; p-value=0.011) and non-ischemic late gadolinum enhancement (LGE) (62.5% vs 29.8%;p-value=<0.001) were observed in the population with prior COVID-19 infection compared to control. No admission factors were found to be related with the increases in nonischemic LGE/abnormal T1.

Conclusion: There is a significant increase of myocardial fibrosis prevalence in patients with CVD one year post-COVID-19 hospitalization compared to control assessed through cMRI parameters. No relationships were found between admission factors and myocardial fibrosis. "

"Bedah jantung terbuka merupakan salah satu tindakan untuk memperbaiki kondisi kelainan anatomis pada pasien dengan berbagai kelainan jantung yang pasti menggunakan mesin CPB (Cardiopulmonary bypass). Penggunaan mesin ini menimbulkan hemodilusi yang berakibat pada penurunan kadar hemoglobin darah pascabedah. Pada pasien pediatrik, efek hemodilusi yang terjadi lebih besar dibandingkan dengan pasien dewasa. Penelitian sebelumnya berhasil mengidentifikasi bahwa sebagian besar pasien mengalami komplikasi pascabedah, dengan mortalitas sebesar 13,6%. Hemoglobin pascabedah dihipotesiskan menjadi faktor yang kuat dalam mortalitas pasien. Penelitian kohort retrospektif ini menghimpun data hemoglobin pascabedah dari rekam medik elektronik pasien yang menjalani bedah jantung terbuka di Pelayanan Jantung Terpadu Rumah Sakit Dr. Cipto Mangunkusumo pada Januari 2021 hingga Desember 2022 dilanjutkan dengan uji komparatif pada kelompok dengan dan tanpa mortalitas. Total 317 pasien diikutkan dalam penelitian ini. Mortalitas secara umum sebesar 11,7%. Hemodilusi teramati pada populasi pasien. Tidak ditemukan perbedaan signifikan dari hemoglobin pascabedah pada kelompok pasien dengan dan tanpa mortality (p=0,249). Didapatkan pula besar penurunan Hb prabedah ke pascabedah berbeda secara signifikan pada kedua kelompok tersebut (p<0,05). Hemoglobin pascabedah tidak berhubungan dengan mortalitas pasien pediatrik.

Open heart surgery is a procedure aimed to correct anatomical abnormalities in patients with various heart conditions, invariably employing the use of a Cardiopulmonary Bypass machine. The use of this machine induces hemodilution, resulting in a decrease in postoperative blood hemoglobin levels. In pediatric patients, the hemodilution effect is more pronounced compared to adult patients. Previous study showed that a significant proportion of patients experience postoperative complications, with a mortality rate of 13.6%. Postoperative hemoglobin is hypothesized to be an important factor in patient mortality. In this study, a retrospective cohort observational study was conducted to compare postoperative hemoglobin levels in patients with and without mortality. The data were obtained from the medical records of patients undergoing open heart surgery at the Integrated Cardiac Services at Dr. Cipto Mangunkusumo Hospital from January 2021 to December 2022. Total of 317 patients included in this study and overall patient mortality was 11,7%. There was no significant difference in postoperative hemoglobin in the groups of patients with and without mortality (p=0,249). This study also found that the decrease in Hb from pre-surgery to post-surgery was significantly different between the two groups (p<0,05). Postoperative hemoglobin is not associated with mortality in pediatric patients."

"La pathologie vasculaire digestive reste méconnue. Elle est rare, protéiforme, de traitement parfois complexe. Les auteurs ont eu l’opportunité de réunir dans le même établissement de santé plusieurs médecins de spécialités différentes : anesthésistes réanimateurs, gastro-entérologues, spécialistes en médecine vasculaire, nutritionnistes, radiologues, angéiologues et chirurgiens, qui se sont impliqués dans la prise en charge de la pathologie vasculaire digestive.Ils ont réalisé un ouvrage collectif où ils font la synthèse, à la lumière de leur expérience, des dernières mises au point en pathologie vasculaire digestive. Sont abordés en particulier les ischémies intestinales aiguë et chronique, les colites et rectites ischémiques, les infarcissements veineux du grêle et du côlon, les anévrysmes et les dissections spontanées, les traumatismes ainsi que d’autres pathologies vasculaires plus rares pouvant toucher le tube digestif.Le fait de travailler en équipe depuis plusieurs années donne aux auteurs une vision globale de ce sujet qui se traduit dans l’homogénéité de l’ouvrage. L’utilisation d’une illustration abondante et didactique facilite la lecture et la compréhension."

"This book provides an up-to-date introduction to the role circadian rhythms, cardiac plasticity, and mechanotransduction play in the heart, while at the same time introducing new developments in cellular, viral, and non-biologic therapies that are in the process of being developed. Importantly, the focus of this book is on topics that, due to their novelty, are largely not covered in the other major textbooks. A special emphasis is placed on the molecular basis of cardiac metabolism, new concepts in cardiac remodeling, and translational therapies and imaging techniques currently under development for clinical use. The chapters are written by experts from diverse clinical and biomedical research backgrounds. Translational cardiology : molecular basis of cardiac metabolism, cardiac remodeling, translational therapies and imaging techniques simplifies the complexity of the molecular basis of disease by focusing on patient-oriented disease mechanisms and therapies and is of great value to a broad audience including physicians (e.g. cardiologists, cardiovascular surgeons, pathologists) as well as translational biomedical researchers in a wide range of disciplines."
