Arrhythmias after orthotopic heart transplantation.

BACKGROUND: Arrhythmias frequently occur after orthotopic heart transplantation (OHT). METHODS AND RESULTS: The most common are ventricular premature complexes, atrial premature complexes, sinus or junctional bradycardia, atrial fibrillation, and atrial flutter, all of which have varying clinical significance depending on associated or causative conditions. Unique etiologic factors such as allograft rejection, transplant coronary artery disease, and altered anatomy and autonomic nervous system changes require that arrhythmias be treated differently after OHT compared with the general population. CONCLUSION: The potentially severe ramifications of allograft rejection and coronary artery disease make treatment of these disorders in the setting of arrhythmias as important as treating the arrhythmias themselves. At the same time, autonomic denervation and altered anatomy after transplantation complicate drug and device therapies.

Decreased recipient survival following orthotopic heart transplantation with use of hearts from donors with projectile brain injury.

BACKGROUND: Fatal gunshot injury to the brain can cause significant alterations in the neuroendocrine state and myocardial dysfunction. Therefore heart allografts from these donors may result in graft failure following orthotopic heart transplantation (OHTx). We evaluated whether receiving a heart from a donor who died from fatal gunshot wound to the brain independently affected the outcome of transplantation. METHODS: A retrospective review of 113 consecutive patients undergoing OHTx at a university hospital from 1996 to 2002 was performed. Group 1 received hearts from donors with fatal gun shot brain injury (n = 17), and Group 2 received hearts from donors who died from other causes (n = 96). RESULTS: Recipient age, gender, United Network for Organ Sharing (UNOS) status, indication for transplantation, and other co-morbid conditions were similar in both groups. Young male donors pre-dominated in Group 1, but other donor characteristics were not significantly different. The incidence of Grade 3A rejection was higher in Group 1 than Group 2 (35% vs 6.3%, p = 0.003), as was the incidence of post-operative infection (35% vs 7.2%, p = 0.004). Actuarial survival at 1 and 5 years was significantly lower in Group 1 than in Group 2 (81% and 74% vs 97% and 94%, respectively, p = 0.005). Multivariate logistic regression analysis also demonstrated that fatal gunshot brain injury, as cause of donor death, was a risk factor for recipient mortality (p = 0.01). CONCLUSION: Receiving a heart from a donor with fatal gunshot brain injury is a significant risk factor for recipient mortality following OHTx. Cautious use of heart allograft from these donors, especially in low-risk recipients, may lead to improved outcome following heart transplantation.

Consensus statement: Palliative and supportive care in advanced heart failure.

BACKGROUND: A consensus conference was convened to define the current state and important gaps in knowledge and needed research on "Palliative and Supportive Care in Advanced Heart Failure." EVIDENCE: Evidence was drawn from expert opinion and from extensive review of the medical literature, evidence-based guidelines, and reviews. CONCLUSIONS: The conference identified gaps in current knowledge, practice, and research relating to prognostication, symptom management, and supportive care for advanced heart failure (HF). Specific conclusions include: (1) although supportive care should be integrated throughout treatment of patients with advanced HF, data are needed to understand how to best decrease physical and psychosocial burdens of advanced HF and to meet patient and family needs; (2) prognostication in advanced HF is difficult and data are needed to understand which patients will benefit from which interventions and how best to counsel patients with advanced HF; (3) research is needed to identify which interventions improve quality of life and best achieve the outcomes desired by patients and family members; (4) care should be coordinated between sites of care, and barriers to evidence-based practice must be addressed programmatically; and (5) more research is needed to identify the content and technique of communicating prognosis and treatment options with patients with advanced HF; physicians caring for patients with advanced HF must develop skills to better integrate the patient's preferences into the goals of care.
