Sexual Quality of Life in Left Ventricular Assist Device Patients and Their Partners.

Background: Living with a left ventricular assist device (LVAD) comes with potentially burdensome aspects posed by, for example, battery packs and device drivelines. We aim to describe the impact of living with a durable LVAD on sexual quality of life (QOL), depression, and anxiety in patients and their partners.

Methods And Results: In this single-center, prospective, observational study, patients ≥4 months after LVAD implantation and their partners completed the Sexual Activities in Left Ventricular Assist Device Patients or Partners questionnaire to assess their sexual QOL, the 8-item Patient Health Questionnaire (PHQ-8) to assess symptoms of depression and the 7-item Generalized Anxiety Disorder (GAD-7) to assess symptoms of anxiety.

Redefining the molecular rejection states in 3230 heart transplant biopsies: Relationships to parenchymal injury and graft survival.

The first-generation Molecular Microscope (MMDx) system for heart transplant endomyocardial biopsies used expression of rejection-associated transcripts (RATs) to diagnose not only T cell-mediated rejection (TCMR) and antibody-mediated rejection (ABMR) but also acute injury. However, the ideal system should detect rejection without being influenced by injury, to permit analysis of the relationship between rejection and parenchymal injury. To achieve this, we developed a new rejection classification in an expanded cohort of 3230 biopsies: 1641 from INTERHEART (ClinicalTrials.

The impact of active cytomegalovirus infection on donor-derived cell-free DNA testing in heart transplant recipients.

Background: Little is known about the relationship between cytomegalovirus (CMV) infections and donor-derived cell-free DNA (dd-cfDNA) in heart transplant recipients.

Methods: In our study, CMV and dd-cfDNA results were prospectively collected on single-organ heart transplant recipients. If the CMV study was positive, a CMV study with dd-cfDNA was repeated 1-3 months later.

Three-year outcomes of de novo tacrolimus extended-release tablets (LCPT) compared to twice-daily tacrolimus in adult heart transplantation.

Background: Extended-release tacrolimus for prophylaxis of allograft rejection in heart transplant (HT) recipients is currently not FDA-approved. One such extended-release formulation of tacrolimus known as LCPT allows once-daily dosing and improves bioavailability compared to immediate-release (IR-) tacrolimus. We compared long-term efficacy and safety of LCPT to IR-tacrolimus applied de novo in adult OHT recipients.

Bioimpedance Spectroscopy in Heart Transplantation: Posttransplant Changes in Body Composition and Effects in Outcomes.

Background: Bioimpedance spectroscopy yields measurements of fat-free mass, fat mass, phase angle, and other measures. Bioimpedance spectroscopy has been validated as a preoperative assessment tool in cardiac surgical studies, in which low phase angle predicted morbidity and mortality. No studies have evaluated bioimpedance spectroscopy following heart transplantation.

The Utility of Home Sleep Apnea Testing in the Advanced Heart Failure Populations.

Untreated sleep disorders form a risk of coronary artery disease, hypertension, obesity, and diabetes mellitus. Access to polysomnography is limited, especially during the COVID-19 pandemic, with home sleep apnea testing (HSAT) being a potentially viable alternative. We describe an HSAT protocol in patients with advanced heart failure (HF).

Heart transplant Recipients' perspectives on invasive versus Non-invasive graft failure surveillance Methods.

Background: Heart transplant recipients must regularly be assessed for graft rejection; however, endomyocardial biopsy (EMB), can be stressful, painful, and inconvenient. AlloMap® is the only commercially available non-invasive test for graft rejection. Current guidelines include AlloMap® testing in low-risk patients OBJECTIVES: To examine the patients' perspective, this study compared patients' experiences of AlloMap® and EMB surveillance at our center.

Urinary Cell-Cycle Arrest Biomarkers as Early Predictors of Acute Kidney Injury After Ventricular Assist Device Implantation or Cardiac Transplantation.

Objectives: Acute kidney injury (AKI) remains a leading source of morbidity and mortality after cardiothoracic surgery. Insulin-like growth factor-binding protein 7 (IGFBP7), and tissue inhibitor of metalloproteinases-2 (TIMP-2), are novel early-phase renal biomarkers that have been validated as sensitive predictors of AKI. Here the authors studied the efficacy of these biomarkers for predicting AKI after left ventricular assist device (LVAD) implantation and cardiac transplantation.

De novo tacrolimus extended-release tablets (LCPT) versus twice-daily tacrolimus in adult heart transplantation: Results of a single-center non-inferiority matched control trial.

Extended-release tacrolimus for prophylaxis of allograft rejection in orthotopic heart transplant (OHT) recipients is currently not FDA-approved. One such extended-release formulation of tacrolimus known as LCPT allows once-daily dosing and improves bioavailability compared to immediate-release tacrolimus (IR-tacrolimus). We compared the efficacy and safety of LCPT to IR-tacrolimus applied de novo in adult OHT recipients.

Pneumothorax and Pneumomediastinum in COVID-19 Suggest a Pneumocystic Pathology.

Objective: To determine whether the apparent excess incidence of pneumothorax and pneumomediastinum in patients with coronavirus disease 2019 (COVID-19) is explained adequately by iatrogenic causes vs reflecting sequelae of severe acute respiratory syndrome coronavirus 2 infection.

Patients And Methods: We retrospectively reviewed patients within our health care system from March 15, 2020, through May 31, 2020, who had a diagnosis of pneumothorax or pneumomediastinum during hospitalization for confirmed COVID-19 infection with attention to timing of pneumothorax and pneumomediastinum; presence, laterality, and placement, or attempts at central lines; and presence of mechanical ventilation before the event.

Results: We report clinical data and outcomes from 9 hospitalized patients with COVID-19 who developed pneumothorax and/or pneumomediastinum among more than 1200 hospitalized patients admitted within our hospital system early in the pandemic.

Usefulness of endobronchial stenting for nonmalignant right middle lobe syndrome.

We report herein a case of nonmalignant middle lobe atelectasis of the right lung resulting in significant stenosis of the airway. The new short self-expandable metallic stents (SEMS) were used to perform temporary stenting and expansion of the right middle lobe airway. SEMS have been used to treat airway obstructions in the trachea, as well as the right and left carina, but few studies have looked at placing SEMS at the level of the bronchi, especially right middle lobe bronchus.

Unexpected Twists: A 61-Year-Old Male with Repeated HeartMate II Complications andSubsequent Replacement with HeartMate III.

An outflow graft twist of a left ventricular assist device (LVAD) remains a challenging clinical diagnosis and may even be misdiagnosed for other outflow obstructions. We present a case of a patient with two LVAD exchanges due to suspected outflow graft twisting in both clinical scenarios. As new LVADs continue to be designed and upgraded, clinicians must have a high index of suspicion for this rare complication.

ALLY in fighting COVID-19: magnitude of albumin decline and lymphopenia (ALLY) predict progression to critical disease.

The global severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic leading to coronavirus disease 2019 (COVID-19) is straining hospitals. Judicious resource allocation is paramount but difficult due to the unpredictable disease course. Once hospitalized, discerning which patients may progress to critical disease would be valuable for resource planning.

Outpatient COVID-19 surveillance testing in orthotopic heart transplant recipients.

Unlabelled: COVID-19 case fatality rate in the United States is currently reported at 4.8% based on the confirmed cases of COVID-19. However, there are conflicting reports of estimated deaths in the post-cardiac transplantation patient population associated with COVID-19.

Usefulness of harmonica playing to improve outcomes in patients with chronic obstructive pulmonary disease.

Pulmonary rehabilitation in chronic obstructive pulmonary disease (COPD) includes a multidisciplinary approach of exercise and pursed-lip diaphragmatic breathing. Pursed-lip diaphragmatic breathing reduces alveolar collapse during exhalation, and diaphragmatic breathing improves inspiratory pressures. Harmonica playing has maneuvers similar to those taught in pursed-lip diaphragmatic breathing, with diaphragmatic breathing to create musical tones.

Tracheal resection for tracheal stenosis.

Anatomically, patients with refractory tracheal stenosis benefit from tracheal resection, depending on the medical comorbidities or challenging tracheal anatomy, which is often the reason for denial of this option in these patients. We evaluated 15 patients undergoing tracheal resection at our institution from May 2016 through December 2017. Eleven patients had a history of previous tracheostomy, six in place at the time of resection.

Left upper lobectomy for a large incidental simple arteriovenous malformation.

We present an incidental finding of a large left upper lobe diffuse pulmonary arteriovenous malformation (PAVM) presenting with cyanosis, exertional shortness of breath, polycythemia, and low peripheral oxygen saturation. PAVMs are mostly diagnosed in symptomatic patients with therapeutic embolization as the first choice of therapy. This young woman had no symptoms but showed signs of hypoxemia, and further investigation revealed a huge central left upper lobe PAVM.

Outcomes of orthotopic heart transplantation and left ventricular assist device in patients aged 65 years or more with end-stage heart failure.

Age has traditionally been a limiting factor for advanced heart failure (HF) therapies. Orthotopic heart transplantation (OHT) age guidelines have become less restrictive, and left ventricular assist devices (LVADs) are increasingly utilized as destination therapy for patients ≥65 years. Although indications differ, we assessed outcomes for both modalities in this older population.

The Effect of Obstructive Sleep Apnea on 3-Year Outcomes in Patients Who Underwent Orthotopic Heart Transplantation.

Despite the well-known association between obstructive sleep apnea (OSA) and cardiovascular disease, there is a paucity of data regarding OSA in orthotopic heart transplant (OHT) recipients and its effect on clinical outcomes. Hence, we sought to determine the association between OSA, as detected by polysomnography, and late graft dysfunction (LGD) after OHT. In this retrospective review of consecutive OHT recipients from 2012 to 2014 at our center, we examined LGD, i.

Salvage of severe primary graft dysfunction following heart transplantation using extracorporeal life support.

Primary graft dysfunction (PGD) is the leading cause of early mortality after heart transplantation. Typically, mechanical circulatory support is necessary to provide hemodynamic support and to enable graft recovery. However, both the reported incidence of PGD and the reported salvage rates with extracorporeal membrane oxygenation (ECMO) vary widely.

Patient "Activation" of Patients Referred for Advanced Heart Failure Therapy.

Advanced heart failure (HF) is a devastating chronic illness requiring complex treatment regimens and patient engagement. Having the information, motivation, and skills to live with a medical condition are conceptualized by the term, "activation." Patients referred for advanced HF therapy and their unpaid family caregiver were invited to participate in this study by completing the 10-item patient activation measure (PAM) questionnaire.
