The Appraisal of Adults with Congenital Heart Disease: Lesson from Comparison of Surgical Outcomes.

The population of adults with congenital heart disease (ACHD) is constantly growing. There seems to be a consensus that these patients are difficult to manage especially if compared to patients with acquired heart disease. The aim of this study is to compare outcomes and results of cardiac surgery in ACHD patients with a reference population of adults with acquired cardiac disease. Retrospective study of 5053 consecutive patients older than 18 years hospitalized for cardiac surgery during a 5-years period in our Institution. Two groups of patients were identified. Group I: 419 patients operated for congenital heart disease; Group II: 4634 patients operated for acquired heart disease. In each Group were identified low, medium, and high-risk patients, according to validated scores. Right ventricular outflow tract surgery was the most frequent procedure in Group I, while coronary artery by-pass grafting was the most common in Group II. Patients with ACHD were younger (37.8 vs. 67.7 years), with higher number of previous operations (32.1% vs. 6.9%), had longer post-ICU hospital stay (11 vs. 8 days) but had lower ICU stay (1 vs. 2 days), shorter assisted mechanical ventilation (12 vs. 14 h) and lower surgical mortality (1 vs. 3.7%) (all p < 0.001). No differences were found in term of post-operative complications (12.4 vs. 15%). The surgical treatment of ACHD patients can be done with excellent results and if compared with acquired cardiac disease patients they have better results with shorter ICU stay and lower mortality.

Modern tools in congenital heart disease imaging and procedure planning: a European survey.

AIMS: Congenital heart diseases (CHDs) often show a complex 3D anatomy that must be well understood to assess the pathophysiological consequences and to guide therapy. Three-dimensional imaging technologies have the potential to enhance the physician's comprehension of such spatially complex anatomies. Unfortunately, due to the new introduction in clinical practice, there is no evidence on the current applications. We conducted a survey to examine how 3D technologies are currently used among CHD European centres. METHODS: Data were collected using an online self-administered survey via SurveyMonkey. The questionnaire was sent via e-mail and the responses were collected between January and June 2022. RESULTS: Ninety-eight centres correctly completed the survey. Of these, 22 regularly perform 3D rotational angiography, 43 have the availability to print in-silico models, and 22 have the possibility to visualize holographic imaging/virtual reality. The costs were mostly covered by the hospital or the department of financial resources. CONCLUSION: From our survey, it emerges that these technologies are quite spread across Europe, despite not being part of a routine practice. In addition, there are still not enough data supporting the improvement of clinical management for CHD patients. For this reason, further studies are needed to develop clinical recommendations for the use of 3D imaging technologies in medical practice.

Single-center experience in percutaneous closure of arterial duct with Amplatzer duct Occluder II additional sizes.

OBJECTIVES: This study aimed to report a large, single-center experience of percutaneous arterial duct (AD) closure using Amplatzer Duct Occluder II Additional Sizes device (ADO II-AS)(St. Jude Medical Corp, St. Paul, MN, USA). BACKGROUND: Transcatheter closure of AD remains challenging in low body weight patients and those who have a persisting shunt following a previous attempt at interventional closure. Recent technical advances in device design may address these issues. METHODS: From May 2011 to April 2016, 109 patients underwent attempted percutaneous closure of AD with ADO II-AS at our Institution. Mean age and weight were 4.8 ± 8.1 years (range 0-48) and 21.4 ± 20.6 kg (range 3-93), respectively. Fifteen patients (13.8%) were ≤6 kg (age 3.5 ± 2.0 months; weight 4.7 ± 1.1 kg). Arterial duct morphology was type A in 62 (57%), type B in 1 (1%), type C in 32 (29%), type D in 7 (6%) and type E in 6 patients (6%), respectively. Arterial approach was used to negotiate and deploy the occluding device in 103 patients (94.5%). RESULTS: AD diameter was 2.2 ± 0.6 (range 1.5-4.5) resulting in QP/QS of 1.9 ± 0.7 (range 1-3.3). Mean pulmonary artery pressure and PA/aortic pressure ratio were 19.3 ± 5.0 mm Hg (range 12-38) and 0.34 ± 0.14 (range 0.14-0.95), respectively. Successful device deployment was achieved in 107 patients (98.2%). Neither procedural morbidity nor mortality was recorded. Immediate, 24h and mid-term (30 ± 17 months) complete occlusion was recorded in 71%, 98.1%, and 100% of patients, respectively. CONCLUSION: In our experience, trans-catheter closure of AD of different sizes and morphologies using ADO II-AS is highly feasible, safe and effective also in challenging anatomic/clinical settings. © 2016 Wiley Periodicals, Inc.

Early Detection of Anthracycline-Induced Cardiotoxicity in Long-Term Survivors of Acute Lymphoblastic Leukemia Treated with Low Cumulative Dose.

We investigated the left ventricular (LV) function, using for the first time strain (S) and strain rate (SR) imaging, in long-term survivors affected by acute lymphoblastic leukemia treated with a low cumulative dose of anthracyclines, and in presence of a normal global LV systolic and diastolic function. A total of 21 were enrolled in the study. The mean cumulative dose of anthracylines was 180 mg/m2 (range: 120-210 mg/m2). As control group 21 age-sex matched healthy subjects were included. Radial S (17 ± 3% vs. 55 ± 6%, P < 0.0001) and SR (2.1 ± 0.3 vs. 3.0 ± 0.8 1\s, P < 0.0001), assessed on the midsegment of the posterior wall from the parasternal views were significantly reduced when compared with controls. Conversely, myocardial performance index was not able to discriminate between patients and controls. In this preliminary study, the myocardial deformation indices appear to be a more sensitive noninvasive technique for detecting subclinical LV dysfunction than other echocardiographic measurements.

Impact of the Amplatzer atrial septal occluder device on left ventricular function in pediatric patients.

Percutaneous closure currently is widely considered to be the first-choice therapeutic option in the treatment of ostium secundum atrial septal defect (ASD). The Amplatzer Septal Occluder (ASO) device is the most used prosthesis, although its influence on cardiac function still is under active investigation. This study aimed to evaluate the impact of the ASO device size on left ventricular (LV) function in pediatric patients using the speckle-tracking strain imaging technology. The study enrolled 43 nonobese pediatric patients submitted to percutaneous ASD closure with the Amplatzer Septal Occluder device and grouped them according to the size of the occluding prosthesis into three groups: a small-device group (≤ 10 mm, group 1), a medium-size-device group (11-16 mm, group 2), and a large-device group (≥ 17 mm, group 3). Echocardiographic data were compared among the groups and with the data of an age-, weight-, and gender-matched control group (50 patients). The large-device group showed a significant impairment in the strain rate value of the basal LV segments. In particular, the mean basal circumferential and radial strain rate values were lower than either normal or the values of the small- and medium-device groups. However, only the absolute device diameter reached statistical significance in the multivariate analysis. The large Amplatzer Septal Occluding device significantly impaired LV systolic function, particularly that of juxtaprosthetic segments, as shown in the strain rate analysis.
