Abstract
OBJECTIVE This study aims to provide an update on the clinical presentation, diagnostic workup, operative strategies, and midterm outcomes in children undergoing ventricular fibroma resection. METHODS Single-center, retrospective cohort study of patients undergoing ventricular fibroma resection between 2000 and 2023. RESULTS Among 52 patients, median age at surgery was 2.0 years (interquartile range, 0.8-4.6) and median tumor volume index was 69 mL/m2 (interquartile range, 49-169). Tumor distorted the atrioventricular valve/subvalvar apparatus in 30 patients (58%) and abutted major epicardial coronary arteries in 41 patients (79%). Surgery was indicated for arrythmia (n = 45, 86%), symptoms (n = 14, 27%), or hemodynamic compromise (n = 11, 21%). Tumor was debulked in 34 patients (65%), including the last 21 patients. Concomitant atrioventricular valvuloplasty was performed in 18 patients and ventricular cavity closure in 15 patients (29%). During a median follow-up of 2.4 years (interquartile range, 0.8-6.2), there was no mortality, cardiac arrests, heart transplants, or single ventricle palliation. The 15-year risk of reoperation and clinical ventricular tachycardia/fibrillation was 6.7% (95% CI, 0-14.3) and 2.4% (95% CI, 0-7.2), respectively. On latest imaging, pre- and postdebulking left ventricular ejection fraction did not significantly differ (P = .069), whereas no patients had signs of outflow tract obstruction, inflow tract obstruction, or moderate or greater atrioventricular valve regurgitation. CONCLUSIONS Large ventricular fibromas can be resected safely with appropriate surgical planning and an emphasis on debulking. Most children maintain left ventricular function and remain free of recurrent ventricular arrhythmias at follow-up. Extended follow-up is warranted to understand whether patients remain at risk for scar-based ventricular arrhythmias in the future.

Heliyon 2023; 9:e19932. [PMID: 37809686 PMCID: PMC10559362 DOI: 10.1016/j.heliyon.2023.e19932] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 07/25/2023] [Accepted: 09/06/2023] [Indexed: 10/10/2023] Open
Abstract
Primary cardiac tumors are rare in all ages, especially in children, with a reported prevalence range of 0.0017-0.28% in autopsy series. Due to their rarity, the diagnostic and therapeutic pathways reserved to them are usually described by single case reports, leading to the point where a common diagnostic protocol is imperative to obtain a differential diagnosis. The first diagnostic approach is done with transthoracic echocardiogram (TTE), due to its wide availability, low cost, absence of ionizing radiations and non-invasiveness. Several tumors are discovered incidentally and, in many cases, TTE is helpful to determine location, size and anatomical features, playing a key role in the differential diagnosis. In the last few years, cardiac magnetic resonance imaging (CMR) has had an increased role in the diagnostic pathway of pediatric cardiac masses, due to its high accuracy in characterizing mass tissue properties (especially for soft tissue), and in detecting tumor size, extent, pericardial/pleural effusion, leading to the correct diagnosis, treatment and follow-up. Therefore, nowadays, several consensus statements consider CMR as a leading imaging technique, thanks to its non-invasive tissue characterization, without the use of ionizing radiation, in an unrestricted field of view. As suggested by the most recent literature, the pediatric protocol is not so different from the adult one, adapted to the size and cardiac frequency of the patient, sometimes requiring special conditions such as free-breathing sequences and/or sedation or general anesthesia in non-cooperating patients.

Abstract
Cardiac tumors in children are rare and the majority are benign. The most common cardiac tumor in children is rhabdomyoma, usually associated with tuberous sclerosis complex. Other benign cardiac masses include fibromas, myxomas, hemangiomas, and teratomas. Primary malignant cardiac tumors are exceedingly rare, with the most common pathology being soft tissue sarcomas. This paper provides consensus-based imaging recommendations for the evaluation of patients with cardiac tumors at diagnosis and follow-up, including during and after therapy.

Heart Rhythm 2023; 20:243-249. [PMID: 36228870 DOI: 10.1016/j.hrthm.2022.10.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Revised: 09/20/2022] [Accepted: 10/05/2022] [Indexed: 11/04/2022]
Abstract
BACKGROUND Ventricular fibromas frequently present with life-threatening ventricular tachycardia (VT) or ventricular fibrillation (VF) in children. The long-term risk of sustained ventricular arrhythmias after surgical resection is unknown. OBJECTIVES The aims of this study were to quantify the VT/VF risk after surgical resection and to examine the results of early (during index surgical hospitalization) and late (≥3 months after surgery) postoperative ventricular stimulation (V-stim) studies. METHODS We performed a retrospective cohort study of all patients with ventricular fibromas who underwent surgical resection at our institution (2000-2020). The primary outcome was defined as recurrent VT/VF ≥3 months after index surgical resection. RESULTS Forty-six patients with a median age at surgery of 2 years (range 0.3-18.9 years) formed our study cohort. Indications for surgery included cardiac arrest in 11 (24%), sustained VT in 16 (35%), premature ventricular contractions/nonsustained VT in 10 (22%), and hemodynamic abnormalities in 9 (20%). Of the 11 patients who presented with cardiac arrest, 4 underwent pre-resection implantable cardioverter-defibrillator (ICD) implantation, all of which were explanted at the time of surgery. An early postoperative V-stim study was performed in 26 (57%) patients, and all were negative for inducible VT/VF. Of the 13 late postoperative V-stim studies, 3 were positive: 2 underwent ICD implantation and 1 was initiated on amiodarone and underwent loop recorder implantation. At the time of last follow-up (median 1.5 years; range 0.3-16.5 years), 45 (98%) were free of clinical VT/VF and no patient with an ICD has received an appropriate shock. CONCLUSION Surgical resection of ventricular fibromas significantly reduces the risk of life-threatening arrhythmias in children; however, a small number of patients remain vulnerable.

Abstract
Cardiac tumors remain rare in children with benign pathologies predominating. Indications for surgical management often result from compromised ventricular chamber size, biventricular outflow tract obstruction, impaired ventricular function, or the presence of medically refractory dysrhythmias. We present a case of a six-month-old infant with two intracardiac fibromas originating in the interventricular septum. The fibromas were causing significant biventricular outflow obstruction. The patient successfully underwent tumor resection on cardiopulmonary bypass The literature on pediatric cardiac tumors is reviewed. Multi-disciplinary medical planning is necessary for successful anesthetic and surgical treatment of this high-risk patient population.

Abstract
Background Pediatric primary cardiac tumors (PCTs) are rare. Its clinical features and prognoses are not well defined. The management of asymptomatic patients with cardiac fibromas remains controversial. Objective We aimed to examine our experience in surgical resection of pediatric PCT, with specific focuses on the management of large fibromas. Methods This study included all the children who underwent surgical resection of PCT in our institution between December 2008 and June 2021. The last follow-up was performed between June 1st and August 26th, 2021. Kaplan–Meier method was used to estimate the postoperative survival, freedom from reoperation, event-free survival, and also related risk factors. The tumor volume and volume index (volume divided by body surface area) were measured for cardiac fibromas. Results Of the 39 patients with median operative age of 9.5 [interquartile range (IQR): 1.2–16.5] years, 35 (89.7%) had benign tumors (fibromas for 15, myxomas for 13, and others for 7). The length and volume of fibromas were independent of age and symptoms (Ps > 0.05). The fibroma volume index was negatively correlated with age (P = 0.039), with a mean value of 105 ± 70 ml/m2. Of the 15 patients with fibromas, 5 were asymptomatic, 4 received partial resection, 4 required transmural resection, and 4 presented postoperative left ventricular (LV) dysfunction (ejection fraction <50%). During the median follow-up period of 3.1 years and maximum of 12.5 years, adverse events included 2 early and 1 late death, 4 reoperations, 4 tumor recurrences, and 1 LV dysfunction lasting over one year. The 8-year survival, freedom from reoperation, and event-free survival rates were 90.4, 81.8, and 64.2%, respectively. Malignant tumor (P < 0.001) was associated with more adverse events. Transmural resection (P = 0.022) and larger tumor volume index than LV end-diastolic volume (P = 0.046) were risk factors for LV dysfunction following fibromas resection. Conclusion Pediatric surgery for PCT can be performed with low mortalities and few adverse events. The size of cardiac fibroma in children relatively decreases with the increase of age. Larger tumor volume index than LV end-diastolic volume index and transmural tumor resection predicts postoperative LV dysfunction.
