ReviewFluoroscopic Imaging for the Interventional Echocardiographer.
Procedural guidance during structural heart disease (SHD) interventions is achieved with both two-dimensional and three-dimensional transesophageal echocardiography as well as real-time fluoroscopic imaging. Although both image the cardiac anatomy, they are based on different principles of image acquisition. In the era of multimodality imaging with coregistration of anatomic landmarks and simultaneous real-time display, it is essential to have cross-disciplinary imaging knowledge. ⋯ In this study, the authors used a novel fluoroscopic phantom cardiac model with enhanced structural markers to display the basic fluoroscopic images used during SHD interventions. The projected images enhance the understanding of the orientation and relationship among intracardiac structures as seen on fluoroscopy. In this study, the authors present the basic fluoroscopic views for SHD interventions and the anatomic relationship for intracardiac structures using a custom-made phantom fluoroscopic heart model.

Hypertrophic Obstructive Cardiomyopathy: Discrepancy Between Hemodynamic Measurements in the Cardiac Laboratory and Operating Room Is to Be Expected.
It is not uncommon to observe some discrepancy in hemodynamic values characterizing left ventricular outflow tract (LVOT) obstruction preoperatively and in the operating room in patients with hypertrophic obstructive cardiomyopathy. Interpretation of this discrepancy can be challenging. To clarify the extent of the discrepancy, the authors compared hemodynamic variables in patients undergoing septal myectomy at the time of preoperative and intraoperative evaluation. ⋯ Discrepancy between hemodynamic measurements in the cardiac laboratory and operating room is common and generally should not affect planned patients' care. These changes in hemodynamics might be explained by preoperative fasting, anesthetic agents, volume shifts while supine, and positive-pressure ventilation, as well as the difference in measurement techniques.

Physical Therapy and Sedation While on Extracorporeal Membrane Oxygenation for COVID-19-Associated Acute Respiratory Distress Syndrome.
This study aimed to determine whether patients on extracorporeal membrane oxygenation (ECMO) with coronavirus disease 2019 (COVID-19) achieved lower rates of physical therapy participation and required more sedation than those on ECMO without COVID-19. ⋯ The results of this matched cohort study supported that sedation requirements were not dramatically greater and did not significantly limit early physical therapy for patients who had COVID-19-associated ARDS and were on venovenous extracorporeal membrane oxygenation (VV-ECMO) versus those without COVID-19-associated ARDS who were on VV-ECMO.

Observational StudyTrend and Pattern of 100 Acute Respiratory Distress Syndrome Patients Referred for Venovenous Extracorporeal Membrane Oxygenation Treatment in a National Referral Center in North Italy During the Last Decade.
Current evidence supports centralization of patients with refractory acute respiratory distress syndrome (ARDS) to institutions with a high level of expertise and with extracorporeal membrane oxygenation (ECMO) capabilities. The aim of this study was to analyze and report the data of transferred refractory ARDS patients managed with venovenous (VV) ECMO at a national referral center over the last 11 years. ⋯ Referral to a specialized center for VV ECMO treatment should be considered expeditiously in case of refractory ARDS, which often is lethal. Transport of patients with an unstable condition, although challenging, is feasible, and centralization of patient care is associated with good outcomes.
