Objectives The primary objective of the present study was to compare cardiac output derived with four methods of QLab (Philips, Amsterdam, Netherlands) software using real-time three-dimensional (3D) transesophageal echocardiography, with cardiac output obtained with the 3D left ventricular outflow tract (LVOT) cardiac output method. The secondary objective was to assess left ventricular (LV) volumes, LV ejection fraction, and cardiac output derived with four different methods of real time 3D tr...
OBJECTIVES Aortic valve replacement (AVR) potentially can modify pulse-wave propagation to the distal aorta. Echo-derived global circumferential strain (GCS) was used to test whether AVR for aortic stenosis (AS) or aortic insufficiency (AI) resulted in differential aortic biomechanics in the descending thoracic aorta. DESIGN This was a prospective observational study of patients who underwent cardiac surgery between 2016 and 2019. SETTING Weill Cornell Medicine, a single large academic medical c...
Objective: To investigate the frequency, predictors, and outcomes of neurologic injury in adults treated with postcardiotomy extracorporeal membrane oxygenation (PC-ECMO). Design: A retrospective multicenter registry study. Setting: Twenty-one European institutions where cardiac surgery is performed. Participants: A total of 781 adult patients who required PC-ECMO during 2010 to 2018 were divided into patients with neurologic injury (NI) and patients without neurologic injury (NNI). Measurements...
Objective The optimal duration of venoarterial extracorporeal membrane oxygenation (VA-ECMO) in patients affected by postcardiotomy cardiogenic shock (PCS) remains controversial. The present study was conducted to investigate the effect of VA-ECMO duration on hospital outcomes. Design Retrospective analysis of an international registry. Setting Multicenter study including 19 tertiary university hospitals. Participants Between January 2010 and March 2018, data on PCS patients receiving VA-ECMO we...
Objectives The authors aimed to evaluate sedation characteristics, as well as cardiorespiratory effects, of propofol, dexmedetomidine, and ketofol used for conscious sedation during transesophageal echocardiography (TEE). Design Prospective double-blind randomized study. Settings Tanta University hospitals. Participants Seventy-five participants with left-to-right shunt requiring diagnostic TEE interventions. Patients were randomized into three groups—P, Dex, and K—to receive propofol, dexmedeto...
Objectives Balloon postdilation (BPD) is one strategy for decreasing paravalvular leakage, but its effect on long-term mortality remains unclear. The authors sought to clarify whether BPD influences long-term mortality of patients with transcatheter aortic valve replacement (TAVR). Design Single-center retrospective study. Setting National heart center; single institution. Participants Participants were patients who underwent TAVR in the authors’ hospital from January 2014 to December 2016. A ba...

Abstract Kounis syndrome is an anaphylactic reaction leading to acute coronary syndrome. The acute treatment of anaphylaxis is epinephrine; however, epinephrine may cause coronary vasoconstriction, reduce coronary blood flow, increase myocardial oxygen demand, and worsen myocardial ischemia. On the other hand, coronary vasodilation, a treatment for acute coronary syndrome, can aggravate hypotension in patients with anaphylaxis. Herein, we report a case of type II Kounis syndrome, with vasospasm ...
The prevalence of heart failure (HF) continues to increase, and its economic effect is significant in the United States and globally. During the past 2 years, a number of high-quality clinical trials were published with the aim of addressing different stages of the disease process and improving outcomes for patients with preserved and depressed ejection fraction (EF). In this review, data from these trials are summarized and critically appraised. There are several important findings from these s...
ABSTRACT Objective Low psoas muscle mass has been previously associated with mortality after TAVR. Evidence from other clinical disciplines suggests that psoas density (PD) may be a better predictor than psoas muscle cross-sectional area indexed to body surface area (PI). We hypothesized that PD would be more strongly correlated with patient discharge disposition and survival after TAVR than PI. Design We performed a single-center, retrospective study of TAVR patients from 2013-2016. PI and PD w...
