Higher perfusion pressure and pump flow during cardiopulmonary bypass are beneficial for kidney function-a single-centre prospective study.

Kidneys play an essential role in the circulatory system, regulating blood pressure and intravascular volume. They are also set on maintaining an adequate filtration pressure in the glomerulus. During the CPB, a decrease in systemic blood pressure and hemoglobin concentration may lead to renal ischemia and subsequent acute kidney injury.

Ministernotomy for aortic valve replacement improves early recovery and facilitates proper wound healing - forced propensity score matching design with reference full sternotomy.

Introduction: With the development of less invasive techniques ministernotomy has become an increasingly popular choice for minimally invasive aortic valve replacement (MIAVR). However, a large discrepancy in the published results, often derived from the center's own experience, intensifies the need for further re-evaluation in order to better define the real impact of the ministernotomy approach on postoperative clinical condition in short- and long-term observation.

Aim: To assess the safety and efficacy of MIAVR in comparison to a reference full sternotomy AVR (FSAVR).

Background: This study aimed to assess long-term results after surgical AVR (sAVR) depending on the used surgical technique (ministernotomy vs. full sternotomy) and to determine which patient- and treatment-related attributes were most associated with shorter time to the main endpoint.

Methods: Out of 2147 patients, who underwent sAVR from January 2006 to December 2017, 615 patients were treated minimally invasively (MIAVR) and 1532 patients received conventional full sternotomy aortic valve replacement (FSAVR).

Early detection of HVAD pump thrombosis based on technical analysis and power consumption measurements.

Background: Continuous-flow left ventricular assist devices (LVADs) have been extensively used in a strategy of bridge to orthotopic heart transplant and destination therapy. The usage of LVAD, however, is not free from limitations such as device-related adverse events, including pump thrombosis (PT). We aimed to develop an algorithm of early PT detection based on the maintenance parameters monitored by the implanted device.

Mechanical circulatory support restores eligibility for heart transplant in patients with significant pulmonary hypertension.

Background: An increasing number of patients with end‑stage heart failure implies a wider use of left ventricular assist devices (LVADs). Irreversible pulmonary hypertension (PH) is a predictor of unfavorable prognosis and a contraindication to orthotopic heart transplant (OHT).

Aims: The aim of this study was to evaluate the effect of continuous‑flow LVAD (CF‑LVAD) support on pulmonary pressure and pulmonary vascular resistance (PVR) as well as the impact of pre‑LVAD hemodynamic parameters on survival during LVAD support.

Simplified, less-invasive left ventricular assist device implantation in patients with post-coronary artery bypass grafting.

Less-invasive left ventricular assist device implantation is becoming the technique of choice for implementation of new-generation heart pumps. The less-invasive technique is particularly useful for patients with a history of cardiac surgical procedures, such as coronary artery bypass grafting. Yet, in redo cases, severe pericardial adhesions may force experienced operators to opt for alternative outflow graft placement, such as in the descending aorta.

Mechanical circulatory support is effective to treat pulmonary hypertension in heart transplant candidates disqualified due to unacceptable pulmonary vascular resistance.

Introduction: High pulmonary vascular resistance (PVR) in orthotopic heart transplantation (OHT) candidates is a risk factor of right ventricle failure after the procedure. However, the increase of PVR may be a consequence of the life-threatening deterioration of the left ventricle function. The use of mechanical circulatory support (MCS) seems to be the best solution, but it is reimbursed only in active OHT candidates.

Emergency HeartWare Ventricular Assist Device (HVAD) exchange due to pump thrombosis using minimally invasive technique.

Left ventricular assist device (LVAD) thrombosis remains a dreadful complication of mechanical circulatory support, with an incidence of 8-12% depending on the pump type and patient's comorbidities. Fibrinolysis may be considered early in pump thrombosis, but when contraindicated a pump exchange remains the only alternative. This short report documents an emergency LVAD exchange in a 55-year-old man who underwent LVAD (HeartWare Inc) implantation in 2013 as a bridge to transplantation.

Von Willebrand factor in patients on mechanical circulatory support - a double-edged sword between bleeding and thrombosis.

Mechanical circulatory support (MCS) is an umbrella term describing the various technologies used in both short- and long-term management of patients with either end-stage chronic heart failure (HF) or acute HF. Most often, MCS has emerged as a bridge to transplantation, but more recently it is also used as a destination therapy. Mechanical circulatory support includes left ventricular assist device (LVAD) or bi-ventricular assist device (Bi-VAD).

Activated Hemostatic Biomarkers in Patients with Implanted Left Ventricle Assist Devices: Are Heparin and/or Clopidogrel Justified?

Background: Adequate anticoagulation represents a major problem for left ventricle assist device (LVAD) utilization in patients awaiting heart transplantation as well as for regeneration of the native heart. The proper management of hemostatic abnormalities during LVAD support may improve survival by reducing the incidence of hemorrhagic and/or thromboembolic complications.
