“…IVC diameter can rapidly reflect the right atrium changes in response to both pressure fluctuations and volume overload . Recent studies showed that caval index, which was defined as the percentage change in the IVC diameter through respiratory cycle, provided more accurate information than IVC diameter for determining volume status . It was demonstrated that caval index was a useful tool in monitoring volume status in unstable critically ill patients admitted to the intensive care units .…”

Inferior vena cava assessment can predict contrast‐induced nephropathy in patients undergoing cardiac catheterization: A single‐center prospective study

Background Contrast‐induced nephropathy (CIN) following cardiac catheterization remains a considerable clinic challenge. Volume status is very important in the development of CIN. It can be assessed noninvasively by measuring inferior vena cava (IVC) diameters. The aim of this study was to assess whether IVC can be used for prediction of CIN in patient undergoing cardiac catheterization. Methods A total of 269 patients undergoing cardiac catheterization were prospectively enrolled in this study. IVC inspiratory and expiratory diameters were measured by transthoracic echocardiography. Caval index was calculated as the percentage decrease in the IVC diameter during respiration. CIN was defined as a ≥0.5 mg/dL and/or a ≥25% increase in serum creatinine within 72 hour post‐procedure. Results Contrast‐induced nephropathy developed in 46 (17.1%) patients after cardiac catheterization. Caval index was significantly higher in patients with CIN than in patients without CIN (47% [40–64] vs 35% [26–50], P < 0.001). In addition, the used contrast volume (145 [90–217] vs 70 [60–100], P < 0.001) and the frequency of percutaneous coronary intervention (50% vs 17.9%, P < 0.001) were significantly higher in patients with CIN than in patients without CIN. In receiver operating characteristic (ROC) curve analysis, caval index ≥ 41% predicted CIN with a specificity of 69% and sensitivity of 72%. Multivariate analysis indicated that caval index ≥ 41% was an independent predictor of post‐procedural CIN development (OR: 3.367, 95% CI: 1.574–7.203, P = 0.002). Conclusions Caval index, a simple and noninvasive echocardiographic marker, is an independent predictor of post‐procedural CIN development in patients undergoing cardiac catheterization.

“…Another way to estimate an individual's intravascular filling state non-invasively is the ultrasound derived inferior vena cava collapsibility index (IVCI) (Finnerty et al 2017). In intensive care patients, IVCI correlates well with invasively measured central venous pressure and pulmonary artery pressure (Stawicki et al 2016;Ilyas et al 2017).

It is generally accepted today that there are two different types of preeclampsia: an early‐onset or placental type and a late‐onset or maternal type. In the latent phase, the first one presents with a low output/high resistance circulation eventually leading in the late second or early third trimester to an intense and acutely aggravating systemic disorder with an important impact on maternal and neonatal mortality and morbidity; the other type presents initially as a high volume/low resistance circulation, gradually evolving to a state of circulatory decompensation usually in the later stages of pregnancy, with a less severe impact on maternal and neonatal outcome. For both processes, numerous dysfunctions of the heart, kidneys, arteries, veins and interconnecting systems are reported, most of them presenting earlier and more severely in early‐ than in late‐onset preeclampsia; however, some very specific dysfunctions exist for either type. Experimental, clinical and epidemiological observations before, during and after pregnancy are consistent with gestation‐induced worsening of subclinical pre‐existing chronic cardiovascular dysfunction in early‐onset preeclampsia, and thus sharing the pathophysiology of cardiorenal syndrome type II, and with acute volume overload decompensation of the maternal circulation in late‐onset preeclampsia, thus sharing the pathophysiology of cardiorenal syndrome type 1. Cardiorenal syndrome type V is consistent with the process of preeclampsia superimposed upon clinical cardiovascular and/or renal disease, alone or as part of a systemic disorder. This review focuses on the specific differences in haemodynamic dysfunctions between the two types of preeclampsia, with special emphasis on the interorgan interactions between heart and kidneys, introducing the theoretical concept that the pathophysiological processes of preeclampsia can be regarded as the gestational manifestations of cardiorenal syndromes.

IMPORTANCE Heart failure (HF) is often characterized by an insidious disease course leading to frequent rehospitalizations and a high use of ambulatory care. Remote cardiac monitoring is a promising approach to detect worsening HF early and intervene prior to an overt decompensation.OBSERVATIONS Recently, a multitude of novel technologies for remote cardiac monitoring (RCM) in patients with HF have been developed and are undergoing clinical trials. This development has been accelerated by the COVID-19 pandemic.CONCLUSIONS AND RELEVANCE This review summarizes the major clinical trials on RCM in patients with HF and present the most recent developments in noninvasive and invasive RCM technologies.
