Non-responders to cardiac resynchronization therapy: Insights from multimodality imaging and electrocardiography. A brief review
2016
Background Cardiac resynchronization therapy (CRT) is a successful strategy for heart failure (HF) patients. The pre-requisite for the response is the evidence of electrical dyssynchrony on the surface electrocardiogram usually as left bundle branch block (LBBB). Non-response to CRT is a significant problem in clinical practice. Patient selection, inadequate delivery and sub-optimal left ventricle lead position may be important causes. Objectives In an effort to improve CRT response multimodality imaging (especially echocardiography, computed tomography and cardiac magnetic resonance) could play a decisive role and extensive literature has been published on the matter. However, we are so fa…
The QRS narrowing index for easy and early identification of responder to cardiac resynchronization therapy.
2013
The rationale for cardiac resynchronization therapy (CRT) in patients with heart failure (HF) is based on the possibility of inducing substantial left ventricular reverse remodeling. It is well known that some of these patients don't benefit from this therapy (the so-called non-responders) [1,2]. No better predictors of a positive answer to CRT than pre-CRT QRS duration (QRSd) were found [3,4]. The aim of our study was to identify a parameter for an easy and early identification of responders to CRT. In this regard, according to Rickard et al., we identified and observed QRS index (QI), as an expression of electrical remodeling after CRT, and its relation with anatomic reverse remodeling, e…
Presurgical evaluation of hemifacial spasm and spasmodic torticollis caused by a neurovascular conflict from AICA with 3T MRI integrated by 3D drive …
2014
Background: Hemifacial spasm (HS) and spasmodic torticollis (ST) are well-known disorders that are caused by a neurovascular conflict. HS is characterized by irregular, involuntary muscle contractions on one side of the face due to spasms of orbicularis oris and orbicularis oculi muscles, and is usually caused by vascular compression of the VII cranial nerve. ST is an extremely painful chronic movement disorder causing the neck to involuntary turn to the side, upward and/or downward. HS is usually idiopathic but it is rarely caused by a neurovascular conflict with the XI cranial nerve. Case Description: We present a case of a 36-year-old woman with a 2-year history of left hemifacial spasm …
Anterior dislocation in a total knee arthroplasty: A case report and literature review.
2015
Dislocations of a total knee arthroplasty (TKA) are an uncommon injury and only few cases of anterior dislocations have been reported. We report a rare case of anterior dislocation of a 10-year-old posterior stabilized total knee arthroplasty in a 74-year-old woman. The patient was successfully treated by close reduction of the dislocation followed by immobilization in full extension with a long leg cast. Because of a high risk of neurovascular complications, a high index of suspicion for vascular injury must be maintained. For this reason, a proper diagnosis is required and immediate reduction is recommended.
Stymulacja pęczka Hisa u osoby starszej z proksymalnym blokiem przedsionkowo-komorowym po zawale mięśnia sercowego
2018
Stymulacja pęczka Hisa (HBP) umożliwia synchronizację przedsionkowo-komorową i międzykomorową. W opisanym przypadku zwrócono uwagę na związek między poziomem bloku, synchronią komorową oraz funkcją rozkurczową u chorego z umiarkowaną dysfunkcją skurczową lewej komory świeżo po zawale serca. HBP jest korzystna w leczeniu zaburzeń przewodzenia i zapobieganiu dalszym zaburzeniom funkcji skurczowej i rozkurczowej. W artykule przedstawiono przypadek 92-letniego mężczyzny w bardzo dobrym stanie psychofizycznym z napadowym blokiem przedsionkowo-komorowym II stopnia i utrwalonym długim odstępem PR w przebiegu zawału mięśnia sercowego bez uniesienia odcinka ST-T, leczonego angioplastyką gałęzi okala…
Optimal control of the Schrödinger equation with two or three levels
2007
In this paper, we present how techniques of “control theory”, “sub-Riemannian geometry” and “singular Riemannian geometry” can be applied to some classical problems of quantum mechanics and yield improvements to some previous results.
On identification of bilingual lexical bundles for translation purposes : the case of an English-Polish comparable corpus of patient information leaf…
2018
Grounded in phraseology and corpus linguistics, this paper aims to explore the use of bilingual lexical bundles to improve the degree of naturalness and textual fit of translated texts. More specifically, this study attempts to identify lexical bundles, that is, recurrent sequences of 3–7 words with similar discursive functions in a purpose-designed comparable corpus of English and Polish patient information leaflets, with 100 text samples in each language. Because of cross-linguistic differences, we additionally apply a number of formal criteria in order to filter out the bundles in each subcorpus. The results show that bilingual lexical bundles with overlapping discourse functions in text…
