Results of new-generation self-expanding transcatheter Porticoтм valve implantation in patients with degenerative aortic stenosis.

Aim    To evaluate 30-day results of the transcatheter correction of degenerative aortic stenosis using a novel self-expandable valve, PorticoTM.Material and methods    Transcatheter aortic valve implantation (TAVI) was performed in 42 patients with an intermediate surgical risk (mean age, 74.3±6.

Endovascular repair of the aorti arch.

Aim: The study was aimed at assessing the in-hospital results of aortic arch endoprosthetic repair using different variants of endovascular supraaortic debranching.

Patients And Methods: The analysis included 27 patients subjected within the framework of aortic arch endoprosthetic repair to various types of supraaortic endobranching, including the technique of parallel prostheses and implantation of fenestrated stent grafts. We analysed the clinical and morphological status of patients prior to operation, peculiarities of the intervention (type of debranching and Ishimaru's classification zones in which the reconstruction was performed) and in-hospital results of treatment.

[Role of magnetic resonance imaging in patients with aortic stenosis before and after replacement of the valve].

Risk stratification among patients with aortic stenosis remains inadequate, and there is a clinical need for the correct identification of high-risk patients who would benefit from aortic valve intervention before developing left ventricular decompensation. Since the publication of the results of the PARTNER study, transcatheter aortic valve implantation (TAVI) has become the method of choice for aortic valve stenosis in inoperable patients and is a real alternative to conventional surgical replacement of the aortic valve in high-risk patients. In planning TAVI and postoperative monitoring of a patient from imaging methods, the leading role is played by echocardiography and multispiral computed tomography.

[Delayed coronary obstruction of the left main artery after transcatheter aortic valve replacement].

Coronary arteries obstruction associated with transcatheter aortic valve implantation (TAVI) may occur either during the procedure or after it. In the latter coronary obstruction can be further divided into early (7 days after procedure) or delayed one (7 days). Delayed coronary obstruction (DCO) is referred as a rare but devastating complication after TAVI and is associated with the extremely high mortality.

[State of the art of the problem concerning endovascular treatment of abdominal aortic aneurysms of infrarenal localization].

The problem concerning diagnosis and treatment of abdominal aortic aneurysms (AAA) is important today because of a high proportion of this pathology within the structure of population morbidity and mortality, with a tendency of these indices to increase, as well as high lethality rates in development of complications. Endovascular treatment of aortic aneurysms is one of the most rapidly developing methods of treatment in vascular surgery. Over the last two decades this type of treatment has been playing an important part in the armamentarium of the vascular surgeon and is often considered as primary treatment of patients with AAA of infrarenal localization.
