Abstract:
Per quanto risulti chiaro come l'innesco della fibrillazione atriale (principalmente parossistica) sia da attribuire a sorgenti focali collocate prevalentemente in prossimità delle vene polmonari (nel 94% dei casi), risulta tutt'ora estremamente dibattuto quali siano i meccanismi di mantenimento di tale anomalia del ritmo cardiaco. Fra le varie teorie riportate in letteratura, una delle più accreditate risulta essere la teoria dei rotori, secondo la quale il mantenimento della FA sarebbe da attribuire a pattern di rotazione spiraliformi, in grado di persistere, come osservato nel celebre studio CONFIRM, per tempi superiori ai 10 minuti. Il presente lavoro di tesi ha quindi l'obiettivo di dare un contributo alla teoria dei rotori, attraverso la realizzazione di mappe di fase ottenute elaborando segnali endocavitari acquisiti durante procedure di ablazione transcatetere con il sistema di mappaggio elettroanatomico CARTO 3 e l'elettrocatetere diagnostico PentaRay, della Biosense Webster. Dopo aver introdotto la fisiopatologia della fibrillazione atriale, soffermandosi particolarmente sulla teoria dei rotori, nel Capitolo 1, e aver introdotto la procedura di ablazione transcatetere, focalizzandosi sull'ausilio del CARTO 3 come sistema di mappaggio real-time, nel Capitolo 2, è stata infatti presentata l'elaborazione eseguita per poter ottenere dai segnali unipolari intracardiaci prelevati, le mappe di fase dalle quali è stata indagata l'eventuale presenza di rotori in 6 pazienti affetti principalmente da FA persistente (Capitolo 3). In conclusione, nell'ultimo capitolo è stata eseguita un'analisi dei risultati, valutando non solamente l'eventuale presenza di rotori nelle regioni della camera atriale in cui sono stati maggiormente osservati in letteratura, ma soffermandosi anche sulla validità dell'elettrocatetere Pentaray nell'indagare la dinamica alla base dei pattern di rotazione spiraliformi.

Abstract:
La fibrillation atriale (FA) est l’arythmie cardiaque soutenue la plus fréquemment rencontrée dans la pratique clinique. Pour la traiter, l’ablation par cathéter de zones cardiaques jugées responsables de soutenir l’arythmie est devenue la thérapie la plus utilisée. Un nouveau protocole d’ablation se base sur l’identification des zones atriales où les électrogrammes (EGM) enregistrés à l’aide d’un cathéter à électrodes multiples, appelé PentaRay, manifestent des décalages spatiotemporels significatifs sur plusieurs voies adjacentes. Ce phénomène est appelé dispersion spatio-temporelle (DST). L’intervention devient ainsi plus adaptée aux spécificités de chaque patient et elle atteint un taux de succès procédural de 95%. Cependant, à l’heure actuelle les zones de DST sont identifiées de manière visuelle par le spécialiste pratiquant l’ablation. Cette thèse vise à identifier automatiquement les sites potentiels d’ablation basée sur la DST à l’aide de techniques d’apprentissage statistique et notamment d’apprentissage profond adaptées. Dans la première partie, les enregistrements EGM sont classés par catégorie en DST vs. non-DST. Cependant, le rapport très déséquilibré entre les données issues des deux classes dégrade les résultats de classification. Nous abordons ce problème en utilisant des techniques d’augmentation de données adaptées à la problématique médicale et qui permettent d’obtenir de bons taux de classification. La performance globale s’élève ainsi atteignant des valeurs de précision et d’aire sous la courbe ROC autour de 90%. Deux approches sont ensuite comparées, l’ingénierie des caractéristiques et l’extraction automatique de ces caractéristiques par apprentissage statistique à partir d’une série temporelle, appelée valeur absolue de tension maximale aux branches du PentRay (VAVp). Les résultats montrent que la classification supervisée de VAVp est prometteuse avec des valeurs de précision, sensibilité et spécificité autour de 90%. Ensuite, la classification des enregistrements EGM bruts est effectuée à l’aide de plusieurs outils d’apprentissage statistique. Une première approche consiste à étudier les circuits arithmétiques à convolution pour leur intérêt théorique prometteur, mais les expériences sur des données synthétiques sont infructueuses. Enfin, nous investiguons des outils d’apprentissage supervisé plus conventionnels comme les réseaux de neurones convolutifs (RNC). Nous concevons une sélection de représentation des données adaptées à différents algorithmes de classification. Ces modèles sont ensuite évalués en termes de performance et coût de calcul. L’apprentissage profond par transfert est aussi étudié. La meilleure performance est obtenue avec un RNC peu profond pour la classification des matrices EGM brutes, atteignant 94% de précision et d’aire sous la courbe ROC en plus d’un score F1 de 60%. Dans la deuxième partie, les enregistrements EGM acquis pendant la cartographie sont étiquetés ablatés vs. non-ablatés en fonction de leur proximité par rapport aux sites d’ablation, puis classés dans les mêmes catégories. Les annotations de dispersion sont aussi prises en compte comme une probabilité à priori dans la classification. La meilleure performance représente un score F1 de 76%. L’agrégation de l’étiquette DST ne permet pas d’améliorer les performances du modèle. Globalement, ce travail fait partie des premières tentatives d’application de l’analyse statistique et d’outils d’apprentissage pour l’identification automatique et réussie des zones d’ablation en se basant sur la DST. En fournissant aux cardiologues interventionnels un outil intelligent, objectif et déployé en temps réel qui permet la caractérisation de la dispersion spatiotemporelle, notre solution permet d’améliorer potentiellement l’efficacité de la thérapie personnalisée d’ablation par cathéter de la FA persistante
Catheter ablation is increasingly used to treat atrial fibrillation (AF), the most common sustained cardiac arrhythmia encountered in clinical practice. A recent patient-tailored AF ablation therapy, giving 95% of procedural success rate, is based on the use of a multipolar mapping catheter called PentaRay. It targets areas of spatiotemporal dispersion (STD) in the atria as potential AF drivers. STD stands for a delay of the cardiac activation observed in intracardiac electrograms (EGMs) across contiguous leads.In practice, interventional cardiologists localize STD sites visually using the PentaRay multipolar mapping catheter. This thesis aims to automatically characterize and identify ablation sites in STD-based ablation of persistent AF using machine learning (ML) including deep learning (DL) techniques. In the first part, EGM recordings are classified into STD vs. non-STD groups. However, highly imbalanced dataset ratio hampers the classification performance. We tackle this issue by using adapted data augmentation techniques that help achieve good classification. The overall performance is high with values of accuracy and AUC around 90%. First, two approaches are benchmarked, feature engineering and automatic feature extraction from a time series, called maximal voltage absolute values at any of the bipoles (VAVp). Statistical features are extracted and fed to ML classifiers but no important dissimilarity is obtained between STD and non-STD categories. Results show that the supervised classification of raw VAVp time series itself into the same categories is promising with values of accuracy, AUC, sensi-tivity and specificity around 90%. Second, the classification of raw multichannel EGM recordings is performed. Shallow convolutional arithmetic circuits are investigated for their promising theoretical interest but experimental results on synthetic data are unsuccessful. Then, we move forward to more conventional supervised ML tools. We design a selection of data representations adapted to different ML and DL models, and benchmark their performance in terms of classification and computational cost. Transfer learning is also assessed. The best performance is achieved with a convolutional neural network (CNN) model for classifying raw EGM matrices. The average performance over cross-validation reaches 94% of accuracy and AUC added to an F1-score of 60%. In the second part, EGM recordings acquired during mapping are labeled ablated vs. non-ablated according to their proximity to the ablation sites then classified into the same categories. STD labels, previously defined by interventional cardiologists at the ablation procedure, are also aggregated as a prior probability in the classification task.Classification results on the test set show that a shallow CNN gives the best performance with an F1-score of 76%. Aggregating STD label does not help improve the model’s performance. Overall, this work is among the first attempts at the application of statistical analysis and ML tools to automatically identify successful ablation areas in STD-based ablation. By providing interventional cardiologists with a real-time objective measure of STD, the proposed solution offers the potential to improve the efficiency and effectiveness of this fully patient-tailored catheter ablation approach for treating persistent AF

Abstract:
Dissertação Apresentada para Obtenção do Grau de Mestre em Engenharia Biomédica
Neste trabalho realizou-se um estudo clínico conducente à obtenção duma relação entre a densidade óptica do cristalino e os parâmetros fluxo, vácuo e potência de ultra-sons, utilizados na cirurgia da catarata – facoemulsificação – de forma a adequar este procedimento cirúrgico a cada patologia de catarata. Para tal, foi utilizado o sistema de diagnóstico oftalmológico Pentacam, para se mediram as densidades ópticas a 23 pacientes e classificar cada catarata em graus através de dois sistemas de classificação: o LOCS III, que classifica as cataratas numa escala de 0 a 6, segundo o tom de cor do núcleo do cristalino, e o PNS, o qual, consoante o valor da densidade óptica do núcleo do cristalino, classifica as cataratas numa escala de 0 a 5. Feita a classificação, obteve-se a relação entre a densidade óptica e os graus da catarata, dos dois sistemas de classificação, que, por sua vez, foram relacionados com os parâmetros da facoemulsificação. Na sequência da classificação das cataratas em graus, não se verificou uma relação entre os valores de densidade óptica e os graus da catarata do sistema LOCS III; enquanto para o sistema PNS constatou-se uma relação linear crescente, até ao Grau 3. A partir deste grau não foi possível tirarem-se conclusões, uma vez que não se obtiveram casos clínicos para os graus 4 e 5. Relativamente à análise da densidade óptica com os parâmetros da facoemulsificação, verificou-se que a densidade aumenta com a diminuição do fluxo e do vácuo, considerando a potência de ultra-sons a mesma para todos os graus. O facto de não se ter observado uma dependência entre a densidade óptica e os graus da catarata do sistema LOCS III, possibilitou concluir que a densidade óptica e a cor do cristalino são métodos diferentes de avaliação da catarata, sendo que um aumento da densidade óptica não implica um tom mais escuro do núcleo do cristalino. Como consequência, conclui-se, de igual modo, que o sistema LOCS III é um método subjectivo, ao passo que o sistema PNS demonstra ser um método mais objectivo. Relativamente ao estudo sobre a facoemulsificação, este mostrou que os valores de fluxo e de vácuo diminuem com o aumento da densidade óptica do cristalino. Tal facto revela ser possível a extracção das cataratas minimizando-se o uso dos ultra-sons, evitando, assim, danos nas estruturas oculares. Acresce-se ainda a esta análise que, quando usado o sistema LOCS III no diagnóstico e avaliação das cataratas, as pupilas devem estar dilatas, no sentido de os valores dos parâmetros da facoemulsificação serem os mais correctos para a avaliação de cada caso clínico.

Abstract:
Polyarene dendrimers are composed entirely of aromatic rings and are of interest as they possess rigid and shape-persistent structures, which have potential applications in materials chemistry and as scaffold for functional molecules. This thesis describes the synthesis and characterisation of a number of new polyarene dendrimers containing pentaphenylbenzene-like (pentaaryl dendrimers) and hexaphenylbenzene-like (hexaaryl dendrimers) branching units which are capable of focal and peripheral expansions. These structures are based on terminal and internal 1,3-dialkyne cores, onto which two polyaryl sections were introduced via Diels-Alder reaction. These compounds possess inherent axial chirality as a result of the dialkyne position on the core, and a range of differently substituted polyaryl units which result in further chiral axes. Several crystal structures of pentaryl dendrimers were obtained, with these crystallising either as meso conformers or conformers with C2 symmetry. Introduction of a chiral auxiliary onto the central aromatic ring of these dendrimers provided evidence of the atropisomers in solution. These were studied via VT 13C NMR, revealing fast rotation and an energy barrier of about 66 kJ mol-1. The presence of additional aromatic rings on a hexaaryl dendrimer enabled observation of atropisomerism in solution owing to the greater steric hindrance of rotation of its branching units about the chiral axes. Fluorine-containing analogues of these dendrimers were synthesised and subjected to conformational studies through 19F-19F Exchange Spectroscopy (EXSY). Qualitative and quantitative analysis of the spectra revealed the kinetic and thermodynamic parameters, showing that the energy barrier of rotation of these dendrimers was within the range of 75-80 kJ mol-1, which was sufficient for spectroscopic observation but not for physical separation. Polyaryls with symmetry or lacking symmetry have been synthesised. The lack of symmetry was achieved by stepwise introduction of the polyaryl fragments. This demonstrates a route to polyaryls with sections possessing different structural features and thus potentially engineered properties and future chemical differentiations.

Разработан метод распознавания роговицы на снимках Pentacam. Предложен метод вычисления радиуса кривизны границ роговицы, опирающийся на их аппроксимацию регрессионным сплайном со штрафной функцией. Построен классификатор, обеспечивающий линейную разделимость классов 0 (норма), 1 степень, 2+3 степень, 4 степень в двухмерном признаковом пространстве: позиция спрямления роговицы, индекс яркости роговицы.
