Aim Aortic stenosis increases left atrial (LA) pressure and may lead to its remodeling. This can cause supraventricular arrhythmia. The aim of this study was to determine if the size of the LA and the presence of atrial fibrillation are related to the prognosis of patients with aortic stenosis.Material and methods Clinical evaluation and standard transthoracic echocardiographic studies were performed in 397 patients with moderate to severe aortic stenosis.Results In all patients, LA dimension above the median (≥43 mm) was associated with a significantly higher risk of death [HR 1.79 (CL 1.06-3.03)] and a LA volume above the median of 80 ml was associated with a significantly higher risk of death [HR 2.44 (CI 1.12-5.33)]. The presence of atrial fibrillation was significantly associated with a higher risk of death (p <0.0001). The presence of atrial fibrillation [HR 1.69 (CI 1.02-2.86)], lower left ventricular ejection fraction [HR 1.23 (CI 1.04-1.45)], higher NYHA heart failure class [HR 4.15 (CI 1.40-13.20)] and renal failure [HR 2.10 (CI 1.31-3.56)] were independent risk factors of death in patients in aortic stenosis.Conclusion The size and volume of the LA and the occurrence of atrial fibrillation are important risk factors for death in patients with aortic stenosis. The presence of renal dysfunction, low left ventricular ejection fraction, high NYHA functional class and atrial fibrillation are independent risk factors of poor prognosis in patients with aortic stenosis.

Introduction: The treatment of choice for aortic stenosis is a valve replacement. Some patients have post-procedural increased pressure gradient on the implanted prosthesis because of patient-prosthesis mismatch (PPM), known to adversely influence prognosis. The PPM risk should be initially predicted and effort made to avoid this complication, specifically in large body size patients. Aim: To assess the frequency of PPM taking into account the valvular prosthesis type in a real-life population of consecutive patients included in the Krakow aortic stenosis registry. Material and methods: The KRAK-AS registry was conducted in July-October 2016. Patients were assessed before and after valve surgery and during the 3-year follow-up. Patients who underwent aortic valve intervention were clinically and echocardiographically evaluated within a month after surgery and divided into groups depending on the implanted prosthesis type. Analysis of patients with a smaller (< 23 mm) and larger than median (≥ 23 mm) valve diameter was performed. Results: The valve implantation was performed in 229 patients (42 mechanical, 139 biological, 48 transcatheter). No differences between patient groups compared by PPM occurrence was seen at baseline. Median age was 70 years; 55.5% were men. At least moderate PPM (iEOA ≤ 0.85 cm2/m2) was observed in 40% of mechanical valves, 33% of biological valves, and was significantly less frequent (10%) in patients after transcatheter valve implantation, p = 0.0001. Severe PPM (iEOA < 0.65 cm2/m2) was found in 17.6% of mechanical valve PPM patients, 4.3% of biological ones, and no patients after transcatheter procedure. Conclusions: PPM is a frequent phenomenon in the real-life population of patients undergoing surgical aortic valve replacement, being significantly less frequent in the case of a transcatheter procedure.
ABSTRACT
OBJECTIVE: Aim: The analysis of dietary knowledge and habits of patients with aortic stenosis, both prior to and post valve implantation. PATIENTS AND METHODS: Materials and methods: Patient with diagnosed moderate or severe aortic stenosis were included into the study. Telephonic dietary interview was performed. It was based on the standard KomPAN questionnaire developed and validated by the Behavioural Nutrition Team, Committee of Human Nutrition of Polish Academy of Sciences. RESULTS: Results: The analysis was conducted in 94 consecutive patients. The pro-health diet index was 4.87 points (3.7; 5.96), while the optimal level was defined as 20 points. The 12.8% of the respondents had low knowledge about nutrition, 79.8% - moderate and 7.4% - good. From 94 patients, 37 had the patientprosthesis mismatch and overweight. The 35.1% of patients with the patient-prosthesis mismatch and overweight considered their nutritional habits as bad, 62.2% as moderate and 2.7% as good. In a group of patients without the patient-prosthesis mismatch the self-opinion about diet was bad in 20.8%, moderate in 72.9% and good in 6.3%. CONCLUSION: Conclusions: Dietary habits and nutritional knowledge in patients with aortic stenosis are inadequate. However, awareness of bad dietary habits in patients who are overweight and have patient-prosthesis mismatch is better compared to the remaining group of patients. The proper dietary education is needed in all patients with aortic stenosis.
