“…Using a combination of pulse contour analysis and the Granov Goor Index (GGI) based on the systolic time intervals (STI) which similarly to left ventricular ejection fraction (LVEF)-can assess cardiac function and provide information on several circulatory parameters and volume status. The technology underwent several validation studies compared to Swan-Ganz-and PICCO®catheterisation techniques [4][5][6][7][8].…”

“…Moreover, these parameters may offer an accurate tool for tailored peri and post procedural in-hospital management and for discharge planning. hemodynamic parameters in an easy non-invasive manner and that can be used bedside at any time for repeated measurements [4,5]. The present series aim to report on feasibility and reproducibility of these measurements to illustrate short-term in-hospital hemodynamic outcomes in unselected patients subjected to transfemoral TAVI.…”

Objectives and Background: To investigate short-term hemodynamic improvement following transcatheter aortic valve implantation (TAVI) in patients with severe aortic valve stenosis (AS) using the non-invasive NICaS ® whole body electrical bio-impedance monitoring system. Methods: 52 unselected patients subjected to TAVI were analysed between January and September 2018. Endovascular TAVI was applied in local anaesthesia and analgosedation in all patients using the Medtronic Evolut R ® (n=32), Edwards Sapien 3 ® (n=14) or Boston Scientific SYMETIS ACURATE neo ™ TF ® (n=4) system. NICaS ® measurements were performed at baseline, six to eight hours after TAVI procedure and before discharge. Results and Discussion: When comparing discharge to baseline, there was a successful increase in cardiac output (CO) from 5.01 ± 1.62 to 5.73 ± 1.41 L/min (P=0.009) corresponding to a cardiac index (CI) increase from 2.64 ± 0.80 to 3.13 ± 0.83 L/min/m ² (P=0.002) and of increase in cardiac power index (CPI) from 0.53 ± 0.18 to 0.61 ± 0.16 w/m ² (P=0.008). Additionally, total peripheral resistance (TPR) significantly decrease from 1597.58 ± 624.92 to 1291.29 ± 450.12 dynes * s/cm 5 (P=0.0045) corresponding to a total peripheral resistance index (TPRI) decrease from 2968.88 ± 1078.78 to 2436.72 ± 902.37 dynes * s/cm 5 /m ² (P=0.006). Conclusion: Non-invasive hemodynamic measurements with NICaS ® represent an accurate bedside-tool for monitoring short-term adaptive hemodynamic changes in unselected patients subjected to TAVI. Thus, results can be easily used for tailored peri-procedural management early patients´ mobilization and discharge planning.

“…Intensified clinical and biomarkerbased patient monitoring and early re-evaluation of therapeutic strategies are crucial for therapy management and can favorably influence outcomes. Therefore, supporting straightforward diagnostic tools, such as non-invasive bedside bio-impedance monitoring (NICaS ® NIMedical, Israel Advanced Technology Industries, Hertzliya Pituach 4676672, Israel), provides an accurate and approved method to obtaining hemodynamic parameters in acute and chronic HF [14][15][16][17][18].…”

Background: Little is known about the impact of treatment with inotropic drugs on the interaction of hemodynamics, biomarkers, and end-organ function in patients with acute decompensated heart failure (HF) of different origins and heart rhythms. Methods: Fifty patients with different causes of acute decompensated HF (dilated cardiomyopathy DCM, ischemic cardiomyopathy ICM, atrial fibrillation AF, sinus rhythm/pacemaker lead rhythm SR/PM) were treated with dobutamine or levosimendan. Non-invasive hemodynamics, biomarkers, and parameters of renal organ function were evaluated at hospital admission and after myocardial recompensation (day 5 to 7). Results: Twenty-seven patients with ICM and twenty-three patients with DCM were included. Thirty-nine patients were treated with dobutamine and eleven with levosimendan. Sixteen were accompanied by persistent AF and thirty-four presented either with SR or PM. In the overall cohort, body weight and biomarkers (NT-proBNP/ST2) significantly decreased. GFR significantly increased during therapy with either dobutamine or levosimendan. However, hemodynamic parameters seem to be only improved in patients with DCM, in the levosimendan sub-group, and in patients with SR/PM. Conclusion: Patients with acute decompensated HF benefit from positive inotropic therapy during short-term follow-ups. In particular, patients with DCM, those after levosimendan therapy and those with SR/PM, seem to benefit most from inotropic therapy.

“…Three basic technologies are currently in use for impedance cardiography (ICG): (1) the thoracic ICG (TIC), where the electrodes are placed on the root of the neck and the lower part of the chest, being the dominant method in the market (Patterson et al 1964, Kubicek et al 1966, 1974; (2) the whole-body ICG (ICG WB ), where four pairs of electrodes are used, one pair on each limb (Tischenko 1973, Koobi et al 1999; (3) the regional ICG (RIC), a technology which is used by the NICaS (noninvasive cardiac system). In this technology, which is the subject of this report, only two pairs of electrodes are used, performing best when placed on one wrist and on the contralateral ankle (Cohen et al 1998, Cotter et al 2004, Torre-Amione et al 2004.…”
