Safety and efficacy of repeated balloon aortic valvuloplasty in patients with symptomatic severe aortic stenosis.

Background: Long-term outcomes of balloon aortic valvuloplasty (BAV) in patients with severe symptomatic aortic stenosis (AS) are poor, and this procedure needs to be repeated in selected cases.

Aims: We aimed to investigate the safety and efficacy of repeated BAV (reBAV).

Methods: We included consecutive patients who underwent reBAV in three Polish centers between 2010 and 2019.

Calcium Pattern Assessment in Patients with Severe Aortic Stenosis Via the Chou's 5-Steps Rule.

Background: Progression of aortic valve calcifications (AVC) leads to aortic valve stenosis (AS). Importantly, the AVC degree has a great impact on AS progression, treatment selection and outcomes. Methods of AVC assessment do not provide accurate quantitative evaluation and analysis of calcium distribution and deposition in a repetitive manner.

Predictors of syncope in patients with severe aortic stenosis: The role of orthostatic unload test.

Background: There is a paucity of data regarding response of cerebral blood flow to the postural unloading maneuver and its impact on the risk of syncope in patients with aortic stenosis (AS). The aim of the present study was to assess effects of orthostatic stress test on changes in carotid and vertebral artery blood flow and its association with syncope in patients with severe AS.

Methods: 108 patients were enrolled (72 with and 36 patients without syncope) with severe isolated severe AS.

A novel approach to quantification of aortic valve calcifications in patients undergoing transcatheter aortic valve implantation.

Background: Precise calcium evaluation in the aortic complex may be complicated. We aimed to assess the usefulness of a novel semi-automatic algorithm for multi slice computed tomography-derived (MSCT) quantitative estimation of aortic valve calcifications (AVC) in patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI).

Methods: Ten patients with severe AS who underwent TAVI with Edwards Sapien S3 26 mm prosthesis and had a pre-procedural MSCT scan were included.

Impact of Pre-procedural Cerebrovascular Events on Clinical Outcomes After Transcatheter Aortic Valve Implantation in Patients with Severe Aortic Stenosis.

Background: Transcatheter aortic valve implantation (TAVI) is an increasingly common treatment of symptomatic severe aortic valve stenosis (AS). Thus, it is reasonable to carefully investigate the impact of individual clinical factors on outcomes after TAVI.

Objectives: We aimed to investigate the impact of the previous cerebro-vascular events (CVEs) on outcomes of patients with severe AS undergoing TAVI.

Sex-related differences in clinical outcomes and quality of life after transcatheter aortic valve implantation for severe aortic stenosis.

Introduction: There are inconsistent data on the sex-related differences in clinical outcomes and quality of life (QoL) after transcatheter aortic valve implantation (TAVI).

Aim: We sought to investigate sex-related differences in procedural, clinical and QoL outcomes of TAVI.

Material And Methods: A total of 101 consecutive patients undergoing TAVI were enrolled.

Effect of diabetes mellitus on clinical outcomes and quality of life after transcatheter aortic valve implantation for severe aortic valve stenosis.

Background: Diabetes mellitus (DM) is considered a marker of poor prognosis after cardiac surgery. We sought to investigate the effect of DM on clinical outcomes and quality of life (QoL) after transcatheter aortic valve implantation (TAVI).

Methods: A total of 148 consecutive patients with symptomatic, severe aortic stenosis who underwent TAVI were included.

Prognostic value of tricuspid regurgitation velocity and probability of pulmonary hypertension in patients undergoing transcatheter aortic valve implantation.

Pulmonary hypertension (PH) is associated with adverse clinical outcomes after transcatheter aortic valve implantation (TAVI). We sought to investigate the effects of tricuspid regurgitant velocity (TRV) and echocardiographic probability of PH on clinical outcomes of patients undergoing TAVI. A total of 148 consecutive patients undergoing TAVI were included and stratified as having "low" (TRV ≤2.

Reduced periprocedural mortality and bleeding rates of radial approach in ST-segment elevation myocardial infarction. Propensity score analysis of data from the ORPKI Polish National Registry.

Aims: We sought to evaluate bleeding complications and periprocedural outcomes of the radial approach (RA) as compared to the femoral approach (FA) during percutaneous coronary intervention (PCI) in "real-world" patients with ST-segment elevation myocardial infarction (STEMI).

Methods And Results: The study group consisted of 22,812 consecutive patients with STEMI treated with PCI and stent implantation between January 2014 and June 2015 in 151 tertiary invasive cardiology centres in Poland (the ORPKI Polish National Registry). Patients treated using the RA and FA were compared using a propensity score analysis to avoid possible selection bias.
