Puente a trasplante cardiaco con oxigenación de membrana extracorpórea
2012
PUENTE A TRASPLANTE CARDIACO CON OXIGENACIÓN DE MEMBRANA EXTRACORPÓREA Objetivos: Los nuevos sistemas de Oxigenación de Membrana Extracorpórea (ECMO) han presentado un desarrollo tecnológico notable, fundamentalmente debido a la incorporación de oxigenadores y bombas centrífugas de larga duración, lo cual ha conducido a una importante mejoría en la supervivencia de los pacientes en shock cardiogénico refractario tratados con este tipo de asistencia mecánica circulatoria de corta duración. La implantación de este dispositivo por vía periférica de forma sencilla, rápida y poco agresiva en estos pacientes en shock cardiogénico con signos incipientes de fracaso multiorgánico puede mejorar su su…
Prevention of apoptosis by deferoxamine during 4 hours of cold cardioplegia and reperfusion: in vitro study of isolated working rat heart model.
2002
INTRODUCTION: Heart transplantation is often accompanied by multiple functional alterations, especially in reperfusion period. These are probably related to the reactive oxygen species (ROS) formation catalyzed by transition metals such as iron and copper, and thus the preservation time of the donor hearts is limited. Metabolic protection of the heart grafts is a permanent objective of numerous experiments. Recently, an iron chelator deferoxamine (DFX) was proposed as antioxidant agent for storage solutions in heart grafts. Oxidative stress is also known to mediate the apoptotic cell death in different tissues during ischemia-reperfusion. METHODS: The aim of this study was to evaluate a pos…
Levosimendan in the treatment of patients with acute cardiac conditions: an expert opinion of the Association of Intensive Cardiac Care of the Polish…
2020
Levosimendan is a new inodilator which involves 3 main mechanisms: increases the calcium sensitivity of cardiomyocytes, acts as a vasodilator due to the opening of potassium channels, and has a cardioprotective effect. Levosimendan is mainly used in the treatment of acute decompensated heart failure (class IIb recommendation according to the European Society of Cardiology guidelines). However, numerous clinical trials indicate the validity of repeated infusions of levosimendan in patients with stable heart failure as a bridge therapy to heart transplantation, and in patients with accompanying right ventricular heart failure and pulmonary hypertension. Due to the complex mechanism of action,…
Cardiac reinnervation influences exercise training outcomes in heart transplant patients.

Impact of donor-recipient age on cardiac transplant survival. Subanalysis of the Spanish Heart Transplant Registry.
2020
[Abstract] Introduction and objectives. The age of heart transplant recipients and donors is progressively increasing. It is likely that not all donor-recipient age combinations have the same impact on mortality. The objective of this work was to compare survival in transplant recipients according to donor-recipient age combinations. Methods. We performed a retrospective analysis of transplants performed between 1 January 1993 and 31 December 2017 in the Spanish Heart Transplant Registry. Pediatric transplants, retransplants and combined transplants were excluded (6505 transplants included). Four groups were considered: a) donor < 50 years for recipient < 65 years; b) donor < 50 years for r…
Infectious complications associated with short-term mechanical circulatory support in urgent heart transplant candidates
2021
[Abstract] Introduction and objectives. Short-term mechanical circulatory support is frequently used as a bridge to heart transplant in Spain. The epidemiology and prognostic impact of infectious complications in these patients are unknown. Methods. Systematic description of the epidemiology of infectious complications and analysis of their prognostic impact in a multicenter, retrospective registry of patients treated with short-term mechanical devices as a bridge to urgent heart transplant from 2010 to 2015 in 16 Spanish hospitals. Results. We studied 249 patients, of which 87 (34.9%) had a total of 102 infections. The most frequent site was the respiratory tract (n = 47; 46.1%). Microbiol…
Emergency abdominal surgery after solid organ transplantation: a systematic review
2016
Aims: Due to the increasing number of solid organs transplantations, emergency abdominal surgery in transplanted patients is becoming a relevant challenge for the general surgeon. The aim of this systematic review of the literature is to analyze morbidity and mortality of emergency abdominal surgery performed in transplanted patients for graft-unrelated surgical problems. Methods: The literature search was performed on online databases with the time limit 1990–2015. Studies describing all types of emergency abdominal surgery in solid organ transplanted patients were retrieved for evaluation. Results: Thirty-nine case series published between 1996 and 2015 met the inclusion criteria and were…
What have we learnt 50 years after the first Fontan procedure?
2020
The Fontan procedure is often the only definitive palliative surgical option for patients with a variety of complex CHD sharing in common, a single, dominant ventricle. In recent decades, imaging and therapeutic improvement have played a crucial role in those patients in whom many complications can hamper their life. After 50 years from the first procedure, heart transplantation remains the only definitive treatment for those with a failing Fontan circulation.
Acute heart failure due to giant left atrium: remote ECLS implantation for interhospital transfer and bridging to decision
2018
AbstractBackgroundRemote extracorporeal life support (ECLS) implantation and mobile ECLS are increasingly applied to enable the treatment of patients with refractory heart failure at specialized care centers. Giant left atrium (GLA) is a rare cause but may lead to acute and devastating heart failure.Case reportAcute heart failure that gave rise to a prolonged period of out-of-hospital cardiopulmonary resuscitation in a patient who underwent remote ECLS implantation was found to have resulted from a GLA of impressive dimensions. There having no reasonable option for immediate surgical therapy, the patient was successfully bridged to recovery with a view to subsequent heart transplantation.Co…
