Magnetic resonance imaging physics can be a complex and challenging topic for the practising cardiologist. Its evolving nature and the increasing number of novel sequences used in clinical scanning have been topics of excellent reviews; however, the basic understanding of physics underlying the creation of images remains difficult for many cardiologists. In this review, we go back to the basic physics theories underpinning magnetic resonance and explain their application and use in achieving good quality cardiac imaging, whilst describing established and novel magnetic resonance sequences...

Objectives: Stent implantation for the treatment of aortic coarctation has become a standard approach for the management of older children and adults. Criteria for optimal stent design and construction remain undefined. This study used computational modelling to compare the performance of two generations of the Cheatham-Platinum stent (NuMED, Hopkinton, NY, USA) deployed in aortic coarctation using finite element analysis. Design: Three-dimensional models of both stents, reverse engineered from microCT scans, were implanted in the aortic model of one representative patient...

Aim: Conversion to open repair becomes the last option in case of endovascular repair of abdominal aneurysm failure, when radiological interventional procedures are unfeasible. While early conversion to open repair generally derives from technical errors, aetiopathogenesis and results of late conversion to open repair often remain unclear. Methods: We report data from our Institute's experience on late conversion to open repair. Twenty-two late conversion to open repairs out of 435 consecutive patients treated during a 18 years period, plus two endovascular repair of abdominal aneurysms performed in other centres, are analysed...

REVIEW
Upasana Tayal, Sanjay K Prasad
Myocardial reverse remodeling has been reported to occur in 25-70% of patients with dilated cardiomyopathy. It is not yet fully understood whether remodeling represents disease remission or cure and which hearts retain this capacity to recover. In this review article we discuss the capacity for recovery in DCM, the prognostic implications of this recovery and potential clinical and imaging predictors for myocardial remodeling.

This is the case of a 45-year-old man who was electively admitted to our hospital for revision and extraction of his faulty implantable cardioverter-defibrillator lead and box. The procedure was complicated by cardiac tamponade requiring pericardiocentisis (unsuccessful) and cardiopulmonary resuscitation. The patient was then rushed to theatre for emergency sternotomy and institution of cardiopulmonary bypass. A tear in the superior vena cava was identified and repaired. Unfortunately, the patient suffered of a liver laceration, due to chest compression, which required emergency laparotomy...

Some studies consider the different physical properties of the stent graft when compared with the blood vessel on the basis of vascular lesions that may require further intervention. We present a case in which a patient developed an intramural hematoma at the distal landing of previous thoracic endovascular aortic repair (TEVAR) that required the relining with a flared prosthesis. During follow-up, we observed the appearance of more caudal hematoma. We decided to observe this lesion with close radiological controls...
