The association of pre-transplant atrial fibrillation with in-hospital outcomes in patients undergoing orthotopic liver transplantation: A propensity score matching analysis.

INTRODUCTION: In this study, we sought to evaluate the prevalence and association of pre-transplant atrial fibrillation (AF) on 30-day postoperative outcomes in patients undergoing orthotopic liver transplant (OLT). METHOD: The National Inpatient Sample Database was queried from 2011 to 2017 for relevant ICD-9 and ICD-10 procedural and diagnostic codes. Baseline characteristics and in-hospital outcomes were compared in patients who underwent OLT with AF and those without. RESULTS: Among 45,357 patients who underwent OLT, women made up 35.8% of the overall population. The prevalence of AF before transplant was 2932 (6.5%) with a trend toward increasing prevalence, with an average annual change rate of 4.19%. Applying propensity score matching to control for potential confounding factors, there was no association between pre-transplant AF and in-hospital mortality in patients undergoing OLT, however there was a higher incidence of perioperative complications including: acute kidney injury, ventricular tachycardia, major bleeding, blood product transfusion, and septic shock. CONCLUSION: In patients undergoing OLT, pre-transplant AF is increasing in prevalence and appears to be associated with similar in-hospital mortality but worse perioperative outcomes. Greater emphasis should be placed on AF in the preoperative cardiovascular risk stratification of patients undergoing OLT.

Cardiovascular disease and prevention among people living with HIV in South Florida.

ABSTRACT: Antiretroviral therapy (ART) has improved survival of patients living with HIV (PLWH); however, this has been accompanied by an increase in cardiovascular disease (CVD). Although preventative measures for CVD among the general population are well described, information is limited about CVD prevention among PLWH. The goal of this study was to characterize the prevalence of CVD in our population and to assess the use of primary and secondary prevention.We performed a retrospective review of PLWH receiving primary care at a large academic center in Miami, Florida. We characterized the prevalence of CVD, CVD risk, and the use of aspirin and statins for primary and secondary CVD prevention.A total of 985 charts were reviewed (45% women, 55% men). Average age was 52.2 years. Average CD4 count was 568 cells/microL. 92.9% were receiving ART, and 71% were virologically suppressed. The median 10-year ASCVD risk was 7.3%. The prevalence of CVD was 10.4% (N = 102). The odds of having CVD was lower in patients on ART (OR 0.47, 95% CI: 0.25-0.90, P = .02). The use of medications for primary and secondary prevention of CVD based on current guidelines was low: 15% and 37% for aspirin respectively, and 25% and 44% for statins.CVD risk and rates of CVD are high among PLWH and receiving ART could protect against CVD. However, the use of medications for primary and secondary prevention is low. Increased awareness of CVD risk-reduction strategies is needed among providers of PLWH to decrease the burden of CVD.

In-Hospital Utilization and Outcomes of Palliative Care Consultation in Patients With Advanced Heart Failure Complicated by Cardiogenic Shock Requiring Mechanical Circulatory Support.

Prior studies have shown that the early inclusion of palliative care (PC) specialist is associated with better end-of-life experiences. The National Inpatient Sample Database was queried from 2012 to 2017 for relevant of ICD)-9 and -10 procedural and diagnostic codes to identify patients above 18 years with advanced heart failure (HF) admitted with cardiogenic shock (CS) requiring mechanical circulatory support (MCS). Baseline characteristics, utilization trends and invasive procedures and complications were compared among patients evaluated by PC and those who were not. There were 65,230 patients hospitalized for advanced HF complicated by CS requiring MCS, of these a PC consult was placed in in 9,200 patients (14.1%) and trended upward from 9.4 to 16.8%, between 2012 to 2017. The majority of patients, (37.3%) from the total population died in hospital. In reference to patients who were discharged alive, PC consultation was associated with a lower incidence of invasive procedures such as mechanical ventilation, pacemaker implantation, defibrillator implantation, insertion of percutaneous feeding tubes and tracheostomies performed (p <0.05 for all) whereas complications such as major bleeding, septic shock, transfusion of any blood product were comparable between both cohorts (nonsignificant p value for all). On the other hand, in those patients who died in hospital PC was associated with a lower incidence of pacemaker implantation, defibrillator implantation and insertion of percutaneous feeding tubes (p <0.05 for all). Despite the high morbidity and mortality associated with advanced HF patients with CS requiring MCS, the overall prevalence of PC consultation is exceedingly low. When utilized, the incidence of invasive procedures was lower. This study highlights the underutilization of PC services in this patient population, precluding any perceived benefit in end-of-life experiences.

Mid-ventricle Takotsubo in a Patient with Goodpasture Syndrome.

Takotsubo syndrome (TTS) is characterized by transient, regional systolic dysfunction of the left ventricle, often mimicking acute coronary syndrome. Atypical variants of this syndrome with mid-ventricular, basal, and focal wall motion patterns are increasingly diagnosed and show different clinical features compared to typical TTS. Even though TTS was generally considered a benign condition, continuous and strict monitoring is necessary to diagnose potentially life-threating complications. This is the first case report, to our knowledge, of atypical TTS in a patient with Goodpasture syndrome triggered by acute kidney injury (AKI).

Swinging heart caused by diffuse large B-cell lymphoma.

Pericardial disease is a common complication of solid tumors and occasionally seen in hematologic malignancies. Pericardial effusion, when it occurs, is usually caused by tumor seeding of the pericardium leading to a serous effusion or by mass effect from mediastinal lymphadenopathy blocking drainage of lymphatic ducts. Pericardial disease from non-Hodgkin's lymphoma is uncommon and malignant pericardial effusion is even rarer. Here we present a case of a 31-year-old male with diffuse large B-cell lymphoma who developed cardiac tamponade from a malignant pericardial effusion.

Sex-Specific Outcome Disparities in Patients Receiving Continuous-Flow Left Ventricular Assist Devices: A Systematic Review and Meta-analysis.

Continuous-flow left ventricular assist devices (CF-LVADs) decrease mortality and improve quality of life in patients with advanced heart failure (HF). Their widespread utilization has led to concerns regarding increased adverse effects, especially in women. Nevertheless, sex-specific data remain limited. We searched Medline, Embase, Scopus, and the Cochrane Library for publications reporting sex-specific outcomes after CF-LVADs from January 2008 through January 2017. Outcomes were compared under the random-effects model and heterogeneity examined via χ test and I statistics. A total of 10 studies including 4,493 CF-LVAD recipients were included in the analysis (23.5% women). The overall rate of stroke was significantly higher in women (odds ratio [OR] 1.94; 95% confidence interval [CI] 1.32-2.84; p = 0.0007). This was true for ischemic strokes (OR 2.03; 95% CI 1.21-3.42; p = 0.008) and hemorrhagic strokes (OR 2.03; 95% CI 1.21-3.42; p = 0.008). Women were also more likely to develop right HF necessitating right ventricular assist device (RVAD) implantation (OR 2.12; 95% CI 1.08-4.15; p = 0.03). Other adverse events including renal failure, bleeding, and device-related infection were comparable for both genders. The overall mortality while on CF-LVAD was similar in both groups (OR 1.05; 95% CI 0.81-1.36; p = 0.71). Our analysis suggests that women are at greater risk of significant complications such as cerebrovascular events and right HF necessitating RVAD after CF-LVAD implantation. Further research is needed to better understand the mechanisms underlying these sex-specific outcome disparities.

Accuracy of Voltage Signal Measurement During Radiofrequency Delivery Through the SMARTTOUCH Catheter.

INTRODUCTION: Current methods for measuring voltage during radiofrequency (RF) ablation (RFA) necessitate turning off the ablation catheter. If voltage could be accurately read without signal attenuation during RFA, turning off the catheter would be unnecessary, allowing continuous ablation. We evaluated the accuracy of the Thermocool SMARTTOUCH catheter for measuring voltage while RF traverses the catheter. METHODS AND RESULTS: We studied 26 patients undergoing RFA for arrhythmias. A 7.5F SMARTTOUCH catheter was used for sensing voltage and performing RFA. Data were collected from the Carto-3 3-dimensional mapping system. Voltages were measured during ablation (RF-ON) and immediately before or after ablation (RF-OFF). In evaluating the accuracy of RF-ON measurements, we utilized the RF-OFF measure as the gold standard. We measured 465 voltage signals. The median values were 0.2900 and 0.3100 for RF-ON and RF-OFF, respectively. Wilcoxon signed rank testing showed no significant difference in these values (P = 0.608). The intraclass correlation coefficient (ICC) was 0.96, indicating that voltage measurements were similarly accurate during RF-OFF versus RF-ON. Five patients had baseline atrial fibrillation (AF), for whom 82 ablation points were measured; 383 additional ablation points were measured for the remaining patients. The voltages measured during RF-ON versus RF-OFF were similar in the presence of AF (P = 0.800) versus non-AF rhythm (P = 0.456) (ICC, 0.96 for both). CONCLUSION: Voltage signal measurement was similarly accurate during RF-ON versus RF-OFF independent of baseline rhythm. Physicians should consider not turning off the SMARTTOUCH ablation catheter when measuring voltage during RFA.
