In the last few years, transcatheter aortic valve implantation （TAVI） has become an alternative procedure in patients with severe aortic stenosis and high risk for surgical aortic replacement. Due to the anatomic correlation between aortic valve structure and conduction system of the heart, one of the most common complications after TAVI is conduction system disturbances which including bundle branch block, complete heart block and need for permanent pacemaker implantation. Although these disturbances are usually not lethal, they may have a great influence on patients＇ state and long term-survival. Several risk factors for conduction disturbances have been identified which including age, anatomy of the heart, periprocedural factors, type of implanted valve, preexisting abnormalities and comorbidities. As this technique becomes more familiar to physicians, patients should be carefully screened for risk factors for the development of conduction abnormalities after TAVI in order to provide effective prevention and proper treatment.

Transcatheter aortic valve implantation （TAV1） represents a real revolution in the field of interventional cardiology for the treatment of elderly or high-risk surgical patients with severe symptomatic aortic valve stenosis. Today, TAVI seems to play a key and a reliable role in the treatment of intermediate and maybe low-risk patients with severe aortic stenosis. TAVI has also evolved from a complex and hazardous procedure into an effective and safe therapy by the development of new generation devices. This article aims to review the background and future of TAVI, elinieal trials and registries with old and new generation TAVI devices and to focus on some open issues related to post-procedural outcomes.

One of the main problems of treatment of bifurcation lesions is side branch (SB) stenosis appearing after stent placement in the main vessel. The aim of this study was to create quantitative method for prediction of side branch compromise extent. We accepted that the main mechanism for SB ostial stenosis is flow divider (FD) displacement from stent struts after stent implantation in the main vessel. Using easily measurable parameters from coronary angiography, as SB diameter, angle á (initial angle between axes of parent vessel and SB axis) and angle á' (angle between above mentioned axes after stent placement) we can calculate percentage diameter stenosis at branch ostium (%DS): %DS = sin (á - á')/(tan á). In boundary condition of full FD displacement %DS = cos á. We tested our theoretical predictions with fluoroscopic observation of elastic wall model of bifurcation (45o distal angle between branches) permitting wall deformations with stent. There is full coincidence of values of %DS and percentage area stenosis (%AS). The regular formulas for calculations of %DS and %AS overestimate stenosis severity between 10% and 25%. Our model tests have shown full coincidence between predicted values for %DS and observed values. We demonstrate that part of the SB ostium is not visible in regular angiography and contributes to ostial lumen area. This is a method that permits quantitative prediction of side branch compromise.

The evolving landscape of embolization therapy for treating cerebral aneurysms and brain tumors represents a pivotal stride towards enhancing the efficacy and safety of minimally invasive treatments [1]. Conventional endovascular embolization methods [2], characterized by the manual maneuvering of catheters through the vascular system, present notable limitations in steerability and precision, compounded by the potential health risks associated with prolonged exposure to radiation for surgeons.
