Epidemiology & Indications Global transplant volumes; shifting donor profiles and increased MCS use Common indications: end-stage heart failure refractory to medical therapy, cardiogenic shock despite optimal therapy, select congenital heart disease Relative increase in transplants bridged from durable LVADs
Contraindications & High-Risk Features Absolute: active, uncontrolled infection; active malignancy with high recurrence risk Relative: severe irreversible end-organ dysfunction, significant frailty, uncontrolled substance abuse Special considerations: age, comorbid pulmonary hypertension, prior sensitization
Donor Selection & Allocation Donor–recipient size and blood type compatibility; HLA considerations in sensitized recipients Evolving donor pool: older donors, donors after circulatory death (DCD) in some centers Allocation systems: prioritize urgency, waitlist mortality, geography (varies by country)
Perioperative & Early Postoperative Care (ISHLT 2023) Standard monitoring: continuous ECG, invasive arterial pressure, central venous pressure; early 12‑lead ECG Hemodynamic support: vasopressors/inotropes as indicated; consider MCS if instability persists Glycemic control (target 140–180 mg/dL in ICU), infection prophylaxis, thromboprophylaxis strategies
Mechanical Circulatory Support (MCS) Indications for short-term MCS (ECMO, Impella) vs durable LVAD as bridge-to-transplant ISHLT 2023 MCS guidelines: selection, patient optimization, and timing of transplantation Impact on sensitization, infection risk, thrombosis, and post-transplant outcomes
Rejection Surveillance Endomyocardial biopsy (EMB) remains gold standard for surveillance (schedule varies by center) Noninvasive monitoring: gene-expression profiling, donor-derived cell-free DNA (dd-cfDNA) as adjuncts AMR recognition: clinical, histologic, and immunopathologic criteria; requires high index of suspicion
Antibody-Mediated Rejection (AMR) & Desensitization AMR diagnostic framework and grading (ISHLT/consensus statements) Treatment options: plasmapheresis, IVIG, rituximab, bortezomib, complement inhibition (eculizumab in select cases) Pre-transplant desensitization strategies for highly sensitized patients; importance of multidisciplinary planning
Infectious Disease Considerations Pre-transplant screening (CMV, EBV, TB, fungal exposures), perioperative prophylaxis Post-transplant: CMV prophylaxis strategies based on serostatus, fungal and PCP prophylaxis recommendations Vaccination guidance: inactivated vaccines pre-transplant when possible; live vaccines contraindicated post-transplant
Cardiac Allograft Vasculopathy (CAV) Leading cause of late graft loss; progressive diffuse intimal thickening Surveillance: coronary angiography ± IVUS or CT angiography; noninvasive ischemia testing has limited sensitivity Prevention: risk-factor control, statin therapy early post-transplant, consider mTOR inhibitors in selected patients
Long-Term Complications & Outcomes Infections, malignancy (skin cancers, PTLD), renal dysfunction, CAV, metabolic complications (diabetes, dyslipidemia) Survival: improving 1‑year survival but long-term outcomes shaped by CAV and comorbidities Importance of multidisciplinary long-term follow-up and rehabilitation
Special Populations Pediatric recipients: size-matching, growth, immunosuppression considerations Elderly recipients: careful frailty and comorbidity assessment Patients with prior sensitization, congenital heart disease, re-transplantation considerations
Ethical & Systems Considerations Equitable organ allocation, transparent waitlist practices, and informed consent Resource constraints in some settings—prioritization and program development Importance of transplant registries and quality improvement
Key Takeaways for Clinicians Use multidisciplinary, guideline-driven evaluation pathways (ISHLT 2024 candidate guidance) Optimize MCS timing and manage device-related complications (ISHLT MCS 2023) Vigilant rejection surveillance with combination of EMB and noninvasive tools; be proactive about AMR Early statin therapy, infection prophylaxis, and individualized immunosuppression to improve outcomes
