Innovations in transplant techniques for complex anomalies.

Purpose Of Review: With advances in the field of congenital cardiac surgery and in the management of congenital heart defects in early life, the population of adult congenital heart disease (ACHD) patients is increasing. End-stage heart failure is currently the main cause of cardiovascular mortality and is expected to increase in the coming years. This review summarizes recent innovations in transplant techniques, with special attention to what is known in the population of ACHD recipients.

Ultrasound enhancing agents in cardiovascular imaging: expanding horizons beyond coronary arteries.

From its inception as a two-dimensional snapshot of the beating heart, echocardiography has become an indelible part of cardiovascular diagnostics. The integration of ultrasound enhancing agents (UEAs) marks a pivotal transition, enhancing its diagnostic acumen beyond myocardial perfusion. These agents have refined echocardiography's capacity to visualize complex cardiac anatomy and pathology with unprecedented clarity, especially in non-coronary artery disease contexts.

International Society for Heart and Lung Transplantation Guidelines for the Evaluation and Care of Cardiac Transplant Candidates-2024.

The "International Society for Heart and Lung Transplantation Guidelines for the Evaluation and Care of Cardiac Transplant Candidates-2024" updates and replaces the "Listing Criteria for Heart Transplantation: International Society for Heart and Lung Transplantation Guidelines for the Care of Cardiac Transplant Candidates-2006" and the "2016 International Society for Heart Lung Transplantation Listing Criteria for Heart Transplantation: A 10-year Update." The document aims to provide tools to help integrate the numerous variables involved in evaluating patients for transplantation, emphasizing updating the collaborative treatment while waiting for a transplant. There have been significant practice-changing developments in the care of heart transplant recipients since the publication of the International Society for Heart and Lung Transplantation (ISHLT) guidelines in 2006 and the 10-year update in 2016.

Impact of sodium-glucose cotransporter-2 inhibitor use on peak VO in advanced heart failure patients.

Introduction: Advanced heart failure (HF) is an epidemic that affects multiple organ systems with high morbidity and mortality rates despite optimal medical therapy (OMT) and remains the leading cause of hospitalizations in type 2 diabetes-related cardiovascular disease. The addition of sodium-glucose co-transporter inhibitors (SGLT2i) in treating these patients has seen improved mortality and hospital admission rates. As such, we felt it was important to investigate whether the use of SGLT2i improved functional capacity in patients with HF when compared to OMT by evaluating maximum oxygen consumption (peak VO) using cardiopulmonary exercise testing (CPET).

The Impact of Kinlessness on Older Adults with Advanced Heart Failure.

Markers of social health, including kinlessness, social isolation and loneliness, have important implications for quality of life and health for older adults. As the population ages, there is a growing cohort of kinless older adults without living partners or children, particularly among disadvantaged groups. Kinlessness has been associated with worse mental and physical health, significant unmet care needs, increased risk of dementia, higher rates of long-term placement, and higher mortality rates than those for patients with kin.

Obesity and Weight Loss Strategies for Patients With Heart Failure.

Obesity is a common comorbidity among patients with heart failure with reduced ejection fraction (HFrEF) or heart failure with preserved ejection fraction (HFpEF), with the strongest pathophysiologic link of obesity being seen for HFpEF. Lifestyle measures are the cornerstone of weight loss management, but sustainability is a challenge, and there are limited efficacy data in the heart failure (HF) population. Bariatric surgery has moderate efficacy and safety data for patients with preoperative HF or left ventricular dysfunction and has been associated with reductions in HF hospitalizations and medium-term mortality.

Management of patients with heart failure and chronic kidney disease.

Chronic kidney disease (CKD) and heart failure are often co-existing conditions due to a shared pathophysiological process involving neurohormonal activation and hemodynamic maladaptation. A wide range of pharmaceutical and interventional tools are available to patients with CKD, consisting of traditional ones with decades of experience and newer emerging therapies that are rapidly reshaping the landscape of medical care for this population. Management of patients with heart failure and CKD requires a stepwise approach based on renal function and the clinical phenotype of heart failure.

A Review of Contemporary and Future Pharmacotherapy for Chronic Heart Failure in Children.

This review delves into the most recent therapeutic approaches for pediatric chronic heart failure (HF) as proposed by the International Society for Heart and Lung Transplantation (ISHLT), which are not yet publicly available. The guideline proposes an exhaustive overview of the evolving pharmacological strategies that are transforming the management of HF in the pediatric population. The ISHLT guidelines recognize the scarcity of randomized clinical trials in children, leading to a predominance of consensus-based recommendations, designated as Level C evidence.

Advanced Echocardiography Assessment in the Management of Alcapa Syndrome: Case Report.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare and potentially life-threatening condition affecting infants that requires immediate corrective surgery to restore blood flow to the myocardium. We present a case of an infant with ALCAPA and severe heart failure. What sets this case apart is the utilization of speckle-tracking echocardiography as a non-invasive method for assessing global and regional myocardial function before and after surgical intervention.

Mesenchymal stromal cells to treat patients with non-ischaemic heart failure: Results from SCIENCE II pilot study.

Aims: Allogeneic stem cell therapy is more logistically suitable compared with autologous cell therapy for large-scale patient treatment. We aim to investigate the clinical safety and efficacy profile of the allogeneic adipose tissue derived mesenchymal stromal cell product (CSCC_ASC) as an add-on therapy in patients with chronic non-ischaemic heart failure with reduced left ventricular ejection fraction (HFrEF) < 40%.

Methods And Results: This is a single-centre investigator-initiated randomized phase I/II study with direct intra-myocardial injections of 100 million allogeneic CSCC_ASC.

Dapagliflozin Use in Children with Advanced Heart Failure Undergoing Heart Transplantation: A Matched Case-Control Study.

Dapagliflozin has been associated with euglycemic ketoacidosis in adults with diabetes contributing to poor outcomes when continued prior to surgery. It is unknown if preoperative use of dapagliflozin may lead to adverse events (AE) in nondiabetic children with advanced heart failure (HF) undergoing heart transplantation (HTx). We performed a single-center, matched case-control analysis of nondiabetic primary pediatric HTx recipients < 21 years-old who underwent HTx and followed through postoperative day (POD) 3.

A matter of sex-persistent predictive value of MECKI score prognostic power in men and women with heart failure and reduced ejection fraction: a multicenter study.

Background: A sex-based evaluation of prognosis in heart failure (HF) is lacking.

Methods And Results: We analyzed the Metabolic Exercise test data combined with Cardiac and Kidney Indexes (MECKI) score registry, which includes HF with reduced ejection fraction (HFrEF) patients. A cross-validation procedure was performed to estimate weights separately for men and women of all MECKI score parameters: left ventricular ejection fraction (LVEF), hemoglobin, kidney function assessed by Modification of Diet in Renal Disease, blood sodium level, ventilation vs.

Extrinsic outflow graft obstruction of the HeartMate 3 LVAD: A state-of-the-art review.

While notable improvements in survival, the incidence of hemocompatibility-related adverse events, hospitalizations, and cost have been demonstrated with the only commercially available durable left ventricular assist device, a category of pump malfunctions characterized by outflow graft obstruction has been noted with broader use and clinical follow-up of recipients of this technology. Of particular concern is the accumulation of acellular biodebris between the outflow graft and bend relief covering the outflow graft at its origin with the pump (which we term extrinsic outflow graft obstruction at the bend relief). This process tends to be insidious, occurs late in the postoperative course, can be challenging to diagnose, and can result in significant morbidity and mortality.

Comparison of Intraoperative Blood Product Use During Heart Transplantation in Patients Bridged with Impella 5.5 versus Durable Left Ventricular Assist Devices.

Objective: To determine if the intraoperative transfusion requirements differ based on the mechanical circulatory device used as a bridge to heart transplantation.

Design: A single-center retrospective analysis of intraoperative transfusion requirements in all patients undergoing heart or heart/kidney transplantation between November 2018 and July 2021 who were bridged with a temporary (Impella 5.5) or durable left ventricular assist device (LVAD).

'Hot phase' non-dilated left ventricular cardiomyopathy with atypical onset and recurrence: a case report.

Non-dilated left ventricular cardiomyopathy (NDLVC) is a newly categorized cardiomyopathy phenotype includingseveral aetiologies with a linking characteristic represented by the normal left ventricular volume. Inflammatory heart disease (InHD) is a heterogeneous process with variegate clinical manifestations, sometimes in overlap with NDLVC. A 26-year-old woman was admitted forcomplete heart block (CHB) and persistently raised troponin.

Heart failure biomarkers in hemodialysis patients.

The diagnosis of end-stage renal disease (ESRD) is made when the estimated glomerular filtration rate is less than 15 mL/min/1.73 m2. Most patients with that stage of chronic kidney disease (CKD) are eligible for renal replacement treatment, which includes kidney transplantation, hemodialysis and peritoneal dialysis.

Hypertrophic Cardiomyopathy: From Medical Treatment to Advanced Heart Failure Therapies.

Purpose Of Review: There has been much debate surrounding novel medical therapies and heart transplantation listing challenges in patients with hypertrophic cardiomyopathy (HCM).

Recent Findings: Recent clinical trials led to FDA approval of mavacamten (a cardiac myosin inhibitor), offering symptom relief and potentially delaying/avoiding invasive septal reduction therapies for some patients with HCM and left ventricular outflow obstruction (LVOTO). For those with refractory symptoms and end-stage heart failure, heart transplantation remains the gold standard.

Optimizing Triage of Ambulatory Patients With Advanced Heart Failure: 2-Year Outcomes From REVIVAL.

Background: Left ventricular assist device (LVAD) use remains uncommon in advanced heart failure (HF) patients not dependent on inotropes.

Objectives: Before considering a randomized trial comparing a strategy of earlier use of LVAD to continued medical therapy, a better understanding is needed of the clinical trajectory of ambulatory patients with advanced systolic HF on optimal guideline-directed medical therapy (GDMT).

Methods: REVIVAL enrolled 400 patients with advanced ambulatory systolic HF, ≥1 HF mortality risk marker (≥2 HF hospitalizations past year; or HF hospitalization and high natriuretic peptide; or no HF hospitalizations but low peak oxygen consumption, 6-minute walk, serum sodium, HF survival score or Seattle HF model predicted survival), and no LVAD contraindication at 21 LVAD centers from July 2015 to June 2016.

Outpatient Continuous Intravenous Inotropy in the Modern Era.

The use of continuous inotropy in patients with advanced heart failure (HF) has been historically controversial due to the prevailing notion that it will increase mortality. In practice, clinicians have continued to revisit this idea as there remains a lack of treatment options for patients in stage D HF. Clinical trials in the past have generally not shown favorable effects of long-term chronic infusions of positive IV inotropic agents on symptoms and exercise tolerance.
