Non-Invasive Ultrasound Therapy for Severe Aortic Stenosis: Early Effects on the Valve, Ventricle, and Cardiac Biomarkers (A Case Series).

: Transcatheter aortic valve replacement (TAVR) was developed for inoperable patients with severe aortic stenosis. However, despite TAVR advancements, some patients remain untreated due to complex comorbidities, necessitating less-invasive approaches. Non-invasive ultrasound therapy (NIUT), a new treatment modality, has the potential to address this treatment gap, delivering short ultrasound pulses that create cavitation bubble clouds, aimed at softening embedded calcification in stiffened valve tissue.

Morphogenetic dispositions for variability in acute kidney injury after cardiac surgery: Pilot study.

Background: The aim of our study was to evaluate the degree of genetic homozygosity in cardiac surgical patients with postoperative acute kidney injury (AKI), compared to the subgroup without postoperative AKI, as well as to evaluate antropomorpho-genetic variability in cardiac surgical patients with regard to the presence and severity degree of AKI.

Materials And Methods: The prospective cohort study included an analysis of 138 eligible coronary artery disease (CAD) surgical patients that were screened consecutively. The tested group was divided into three subgroups according to RIFLE criteria: Subgroup NoAKI ( = 91), risk ( = 31), and injury ( = 16).

Pulmonary Artery Hypertension as A Risk Factor for Long-Term Survival after Heart Transplantation.

Background: Heart failure is the most frequent cause of pulmonary artery hypertension (PAH) and its severity may predict the development of heart failure (HF) and is known to be a prognostic factor of poor outcome after heart transplant (HTx). The aim of this study was to investigate the impact of preoperative PAH related to left-sided HF on long-term survival after HTx and to identify the hemodynamic parameters of PAH that predict survival after HTx.

Methods: A prospective observational trial was performed, and it included 44 patients subjected to heart transplantation.

Prevention, treatment and outcomes of left ventricular assist device driveline infections. A single Center experience.

Introduction: While the survival rates for patients with end-stage heart failure have dramatically improved with newer generations of left ventricular assist devices, LVAD-specific infections are important cause of morbidity, mortality, and hospital readmissions in these patients.

Methods: We performed a retrospective analysis of all driveline infections in patients who had undergone LVAD implantation at a single cardiosurgical center. Between June 2013 and March 2017, 51 patients underwent implantation of LVAD.
