Objectives null We evaluated 4384 procedures performed between 1957 and 2018, collected in the National Register for Congenital Heart Defects, conducted on 997 patients with 1823 pulmonary valve replacements (PVRs), including 226 implanted via catheter [transcatheter valve (TCV)]. Main study targets are as follows: TCV benefit, valve type durability, decade-wise treatment changes and procedure frequencies over the lifetime of a PVR patient. null Methods null We studied TCV impact on surgical val...

OBJECTIVES Aortic root dilatation is frequently observed in patients with congenital heart defects (CHD), but has received little attention in terms of developing a best practice approach for treatment. In this study, we analysed our experience with aortic valve-sparing root replacement in patients following previous operations to repair CHD. METHODS In this study, we included 7 patients with a history of previous surgery for CHD who underwent aortic valve-sparing operations. The underlying init...

BACKGROUND In critically ill children, detection of intra-abdominal hypertension (IAH > 10 mmHg) and abdominal compartment syndrome (ACS = IAH + organ dysfunction) is paramount and usually monitored through intra-vesical pressures (IVP) as current standard. IVP, however, carries important disadvantages, being time-consuming, discontinuous, with infection risk through observer-dependent manipulation, and ill-defined for catheter sizes. Therefore, we sought to validate air-capsule-based measuremen...

OBJECTIVES A combined lung and liver transplant in patients with cystic fibrosis (CF) is an uncommon procedure. The goal of this study was to compare long-term outcomes between patients with CF who underwent either a combined lung-liver or a lung-only transplant. METHODS This is a retrospective single-centre study of patients with CF who underwent a lung transplant between January 2005 and May 2020. Since 2006, our preference for a combined lung-liver transplant was to transplant the liver first...

Purpose Lack of organ donors demands transplantation of older lungs into younger recipients. Providing that other general organ donor selection criteria are fulfilled; it still remains questionable whether high age mismatch negatively affects short- and long-term outcomes. Here we investigate outcomes of lung recipients aged between 0 and 50 years whose donors had a high or low age mismatch compared to their respective recipients. Methods Records of patients aged between 0 and 50 years (33±12 ye...

Background: Worse outcomes in women compared to men undergoing left ventricular assist device (LVAD) implantation remain an underestimated problem in heart failure (HF) patients. With device miniaturization, less-invasive LVAD implantation techniques have gained relevance, but their impact on outcomes in women is unknown. This study investigates sex-related differences in patients undergoing LVAD implantation through less-invasive procedures. Methods: This retrospective single-center cohort stud...

The use of lateral thoracotomy (LT) for implanting left ventricular assist devices (LVADs) is worldwide increasing, although the available evidence for its positive effects compared with conventional sternotomy (CS) is limited. This systematic review and meta-analysis analyzes the outcomes of LT compared with CS in patients undergoing implantation of a centrifugal continuous-flow LVAD. Four databases and 1,053 publications were screened until December 2019. Articles including patients undergoing...

Abstract Objective Cardiac valve operations in patients who had undergone solid organ (kidney, liver, pancreas, heart and lung) transplantation pose unique challenges, due to the patient comorbidities and to the need for immunosuppressive therapy. Aim of this retrospective study was to present our experience with solid-organ transplanted patients who had undergone cardiac valve operation at the time or after transplantation. Methods Records of the patients who had undergone cardiac valve operati...

Objectives Our goal was to compare results between a standard computed tomography (CT)-based strategy, the 'three-step preoperative sequential planning' (3-step PSP), for pulmonary valve replacement in repaired tetralogy of Fallot versus a conventional planning approach. Methods We carried out a retrospective study with unmatched and matched groups. The 3-step PSP comprised the planning of mediastinal re-entry, cannulation for cardiopulmonary bypass (CPB) and the main procedure, using standard 3...
