INTRODUCTION Transcatheter aortic valve implantation (TAVI) and minimally invasive aortic valve replacement (minithoracotomy and ministernotomy) have become a valuable alternative to conventional surgical treatment of severe aortic stenosis (AS) in high-risk patients. OBJECTIVESThe aim of the study was to evaluate long-term results and complications in patients with symptomatic AS treated with TAVI, surgical aortic valve replacement (SAVR), minithoracotomy, or ministernotomy. PATIENTS AND METHODSA total of 173 patients with symptomatic AS were enrolled to the study between the years 2011 and 2013. Propensity scores were calculated for TAVI and each surgical method separately. Differences in clinical outcomes between patients treated with TAVI and those treated with surgical methods were adjusted for propensity scores using a logistic regression analysis and presented as adjusted odds ratios with 95% confidence intrervals.RESULTS A median follow-up was 583.5 days (interquartile range, 298-736 days). Before aortic valve replacement (AVR), no significant differences in ejection fraction (EF) were observed between the groups. At 1 week after AVR, mean EF values were significantly higher in patients after TAVI in comparison with the other groups (TAVI, 50.2% ±13.1%; minithoracotomy, 44.1% ±13.4%; ministernotomy, 37.8% ±12.8%; SAVR, 40.3% ±12.5%; P = 0.001). There were no differences in the longest available follow-up mortality between the analyzed groups (P = 0.8). To our best knowledge, this is the first study comparing minithoracotomy, ministernotomy, and SAVR with TAVI in terms of long-term outcomes such as the longest available follow-up mortality, left ventricular (LV) function, complications after the procedure, and conduction disturbances and arrhythmias after the procedure.CONCULSIONS Patients undergoing TAVI show more beneficial long-term outcomes in comparison with patients undergoing minithoracotomy, ministernotomy, and SAVR and do not differ in terms of the longest available follow-up mortality. TAVI seems to have a more favorable effect on LV function and an increase in EF in comparison with the surgical methods.

IntroductionThe extent of peripheral artery disease (PAD) measured by the ankle-brachial index (ABI) and intima-media thickness (IMT) is correlated with the complexity of coronary artery disease (CAD) in stable angina patients. However, data regarding patients with acute coronary syndromes are still lacking.AimTo compare coronary complexity measured by the SYNTAX score in patients with and without PAD presenting with myocardial infarction (MI).Material and methodsBoth ABI and IMT were measured in 101 consecutive patients who underwent primary diagnostic due to MI. Patients were divided into three tertile groups depending on the SYNTAX score (0–4; 5–11; 12 and more points).ResultsMean ABI in the general population was 0.9 ±0.26, mean IMT was 0.8 ±0.3 mm and mean SYNTAX score was 7.8 ±5.4 points. We found significant correlations between ABI and SYNTAX score (p = 0.01), IMT and SYNTAX score (p < 0.001), and IMT and ABI (p < 0.001). The highest mean values of IMT (p < 0.001) and lowest mean values of ABI (p = 0.015) were found in patients in the highest SYNTAX score group. When analyzing receiver operating characteristics (ROC) curves, IMT had greater specificity and sensitivity than ABI.ConclusionsBoth IMT and ABI are correlated with SYNTAX score (positively for IMT and negatively for ABI values). In our study, IMT was a better predictor of SYNTAX score than ABI. Our study suggests that the higher rate of cardiovascular events in patients with PAD presenting with MI may be partially explained by greater coronary lesion complexity.

A b s t r a c tBackground: Radial access during coronary angiography has become an increasingly popular alternative to femoral access. The procedural outcomes and complications of these two approaches have been thoroughly evaluated; however, no studies have focused exclusively on the postprocedural quality of life of patients. Aim:To determine and compare both methods from the patient's point of view.Methods: Data were gathered from 165 consecutive patients scheduled for elective coronary angiography (from October 2011 to June 2012). The choice of the access site was left at operator's discretion. Femoral and radial groups consisted of 91 and 74 patients, respectively. Quality of life was assessed by the Short Form of the McGill Questionnaire and a self-designed questionnaire (Questionnaire II) consisting of eight questions evaluating the procedure-specific aspects of recovery time. After three months from index hospitalisation post-discharge interviews were conducted using a modified version of Questionnaire II with an additional two questions. Conclusions: The quality of life of patients who underwent coronary angiography from radial access was remarkably better in terms of pain characteristic and overall discomfort.

A b s t r a c tBackground: Chronic total occlusions (CTO) are diagnosed in about 20% of patients with significant coronary artery disease. A disproportion between the high prevalence of CTOs and low rate of invasive treatment still exists. Technical difficulties, clinical uncertainties whether patients benefit from recanalisation, and a lack of knowledge of CTO may be responsible for this fact. Aim:To assess the knowledge of coronary arteries CTO among Polish interventional cardiologists. Methods:A self-designed questionnaire was used during two major Polish invasive cardiology workshops held in 2014. Results:The study included 113 physicians, mostly cardiologists certified as independent operators. Average self-declared efficacy of CTO recanalisation was 63.5%. Most of the respondents agreed that the operator involved in the CTO recanalisation program should perform at least 30-50 procedures per year. Only 67% stated that before CTO revascularisation the evaluation of myocardial viability should be performed with dobutamine stress echocardiography as a preferred test. One third of the physicians agreed that CTO percutaneous coronary intervention (PCI) should not be performed directly after diagnostic angiography, and 51.5% believed that in patients with multi-vessel coronary artery disease PCI of CTO should be performed first. Multi-slice spiral computed tomography during the qualification and planning of the CTO revascularisation, in the opinion of 91% of the responders, should not be used before each procedure but could be useful in selected cases. Conclusions:Polish interventional cardiologists remains in compliance with current opinions about recanalisation of chronic coronary artery occlusions and the consensus of the EuroCTO Club, but there is still an unceasing need for further education and promotion of knowledge about CTOs.

IntroductionChronic total occlusion (CTO) recanalization is indicated in patients with symptoms and evidence of ischemia, but in most cases those types of lesions are still treated medically. In the last few years CTO angioplasty technique has changed dramatically due to considerable advances in techniques and dedicated equipment.AimAn attempt to assess the state of knowledge of technical aspects of CTO angioplasty of coronary arteries among Polish interventional cardiologists.Material and methodsQuestionnaire survey performed during two major Polish invasive cardiology workshops.ResultsIn the study there participated 113 physicians with an average length of work experience of 13 years, most of them cardiologists certified as independent primary operators. The majority of respondents recognized the need of prevention of thrombotic complications through control of activated coagulation time during the CTO procedures. Prevention of renal complications and X-ray protection are also recognized as a significant part of the procedures. The benefits from the use of over-the-wire microcatheters and balloons, the proper choice of dedicated guidewires, contralateral injections and retrograde technique are underestimated.ConclusionsDespite satisfactory knowledge about indications and qualification for the CTO procedure, the awareness of procedural aspects (particularly the retrograde technique) as well as the dedicated CTO equipment among Polish interventional cardiologists is still insufficient.
