Sutureless aortic valve replacement (AVR) was developed as an alternative treatment option to conventional open-heart surgery and transcatheter aortic valve implantation for "gray zone" patients. The need for concurrent mitral valve surgery is generally viewed as a contraindication to sutureless AVR. The purpose of this brief paper is to report our experiences with sutureless valves in patients after previous cardiac procedures with degenerated aortic bioprostheses and concomitant mitral valve disease.

Aortic stenosis (AS) is the most common valvular heart disease in adults in Europe and North America. Management of AS patients depends on accurate diagnosis of the cause and stage of the disease process: the first and definitive therapeutic choice for a growing number of elderly patients with symptomatic AS is surgical treatment. In patients not eligible for surgery, transcatheter aortic valve implantation (TAVI) constitutes a safe and effective alternative. As an innovative, costly method of treatment, it requires however careful monitoring of its course, documenting its early and long-term results, and assessment of its safety and medical-economic cost-effectiveness...

Over the past decade, transcatheter aortic valve implantation (TAVI) has evolved rapidly toward an extremely reproducible, safe and effective procedure, with a marked reduction of its related complications. However, the occurrence of conduction disturbances and the need for permanent pacemaker implantation (PPI) after TAVI remains a concern. Areas covered: In this article review, we will go through the mechanisms involved in conduction disturbances after TAVI, and we will discuss the key aspects of pathophysiology, incidence and predictors of conduction disturbances following Transcatheter Aortic Valve Implantation...

PURPOSE OF REVIEW: Sutureless aortic valve replacement (AVR) has emerged as an alternative to traditional AVR for patients with aortic stenosis who present a higher surgical risk, such as the elderly, or those with small or highly calcified aortic roots. With transcatheter aortic valve implantation - the other major AVR alternative - being used in increasingly lower-risk patients, the place of sutureless valves in the AVR landscape needs to be defined. In this review, we discuss recent data and expert opinion as it pertains to the subject of sutureless AVR...

OBJECTIVES: We aimed to determine whether body mass index (BMI) is a prognostic indicator for long-term, all-cause mortality in patients undergoing transcatheter aortic valve implantation (TAVI). BACKGROUND: Obesity in patients with established cardiovascular disease has previously been identified as an indicator of good prognosis, a phenomenon known as the "obesity paradox". The prognostic significance of BMI in patients with severe aortic stenosis (AoS) undergoing TAVI is a matter of current debate, as published studies are scarce and their results conflicting...

BACKGROUND: In this study, we sought to analyze the incidence and relevance of von Willebrand factor (VWF) abnormalities in patients undergoing transcatheter aortic valve implantation (TAVI), especially on perioperative bleeding. Furthermore, we hypothesized that, similar to aortic valve surgery, TAVI results in a restoration of VWF abnormalities. METHODS AND RESULTS: We performed a prospective analysis of periinterventional VWF parameters in 74 patients (80±7years, female in 37...

Blood transfusions are considered as an important predictor of adverse outcome in patients with severe aortic (AS) undergoing transcatheter aortic valve implantation (TAVI). We sought to investigate the association between blood transfusions and mortality after TAVI. We enrolled 101 consecutive patients with severe AS undergoing TAVI. Patients who required transfusion were defined as patients in whom at least one unit of packed red blood cells (PRBCs) was transfused in the perioperative period. Twelve-month outcomes were assessed based on Valve Academic Research Consortium definitions...
