    A rare case of ventricular tachycardia caused by an intramyocardial fibroma with successful surgical resection in an adult
    Binder, M. Scott; Roby, Matthew; Chancellor, William; Yarboro, Leora; Arnold, Scott; Hodge, Kyle; Kern, John; Sane, David (Springer, 2024-09-05)
    Background: Cardiac fibromas are extremely rare in adults. The preferred treatment is surgical resection, but antiarrhythmic medications or heart transplantation have also been used previously. The cardiac imaging, particularly MRI, can be useful to help delineate between primary cardiac tumors, and surgical factors such as the extent/size of the fibroma, involvement of the coronary arteries or mitral apparatus and amount of residual myocardium influence whether surgical resection is feasible. Case presentation: A 42-year-old male presented with a wide-complex tachycardia, unresponsive to amiodarone. An echocardiogram was performed which showed a possible posterior wall mass. A cardiac MRI showed a well circumscribed lateral wall intracardiac fibroma, measuring 5.2 × 5.1 × 3.8 cm with preserved function. Surgical resection was successful, and he was discharged without a defibrillator. Conclusions: Cardiac fibromas are encapsulated tumors which do not infiltrate myocardium and should be surgically resected if possible.

    Background and aim of the study: Postoperative atrial fibrillation (POAF) is a common complication following cardiac surgery which can result in increased mortality and increased healthcare costs. During Hurricane Maria (2017), a nationwide shortage of mannitol occurred, and our institution switched to the utilization of albumin as a priming fluid solution. We observed decreased rates of POAF during that time and began alternating albumin and mannitol priming fluid solutions. We hypothesized this observation may be from altered perinexal conduction from albumin utilization. Methods: A retrospective chart review of all patients from January 2020 through December 2020 who underwent cardiac surgery was performed, to determine if albumin was associated with reduced POAF rates. Two hundred and thirteen patients were identified and 4 were excluded. Two hundred and nine patients (110 albumin priming fluid and 99 mannitol priming fluid) were included in our final analysis. Results: Analysis was performed for all patients with POAF and in patients with new-onset AF (without a history of prior AF) after surgery. POAF rates showed no statistically significant difference between cohorts. For all patients, POAF occurred in 43% of the albumin subgroup and 47% of the mannitol subgroup (p = .53) and for patients with new-onset AF, POAF occurred in 35% of the albumin subgroup versus 42% of the mannitol subgroup (p = .36). Logistic regression revealed that age, ejection fraction and cardiopulmonary bypass time was associated with POAF, in our cohort. Conclusions: The use of albumin compared to mannitol as priming fluid solutions was not associated with statistically significant reductions in POAF rate, in our population.
