Despite the efforts made to improve the care of cardiogenic shock (CS) patients, including the development of mechanical circulatory support (MCS), the prognosis of these patients continues to be ...poor. In this context, CS code initiatives arise, based on providing adequate, rapid, and quality care to these patients. In this multidisciplinary document we try to justify the need to implement the SC code, defining its structure/organization, activation criteria, patient flow according to care level, and quality indicators. Our specific purposes are: a) to present the peculiarities of this condition and the lessons of infarction code and previous experiences in CS; b) to detail the structure of the teams, their logistics and the bases for the management of these patients, the choice of the type of MCS, and the moment of its implantation, and c) to address challenges to SC code implementation, including the uniqueness of the pediatric SC code. There is an urgent need to develop protocolized, multidisciplinary, and centralized care in hospitals with a large volume and experience that will minimize inequity in access to the MCS and improve the survival of these patients. Only institutional and structural support from the different administrations will allow optimizing care for CS.

Introduction
Infection is one of the most significant complications following heart transplantation (HT). The aim of this study was to identify specific risk factors for early postoperative ...infections in HT recipients, and to develop a multivariable predictive model to identify HT recipients at high risk.
Methods
A single‐center, observational, and retrospective study was conducted. The dependent variable was in‐hospital postoperative infection. We examined demographic and epidemiological data from donors and recipients, surgical features, and adverse postoperative events as independent variables. Backwards, stepwise multivariable logistic regression with a P‐value < 0.05 was used to identify clinical factors independently associated with the risk of in‐hospital postoperative infections following HT.
Results
Six hundred seventy‐seven patients were included in this study. During the in‐hospital postoperative period, 348 episodes of infection were diagnosed in 239 (35.9%) patients. Seven variables were identified as independent clinical predictors of early postoperative infection after HT: history of diabetes mellitus, previous sternotomy, preoperative mechanical ventilation, primary graft failure, major surgical bleeding, use of mycophenolate mofetil, and use of itraconazole. Based on the results of multivariable models, we constructed a 7‐variable (8‐point) score to predict the risk of in‐hospital postoperative infection in HT recipients, which showed a reasonable ability to predict the risk of in‐hospital postoperative infection in this population. Prospective external validation of this new score is warranted to confirm its clinical applicability.
Conclusions
In‐hospital postoperative infection is a common complication after HT, affecting 35% of patients who underwent this procedure at our institution. Diabetes mellitus, previous sternotomy, preoperative mechanical ventilation, primary graft failure, major surgical bleeding, use of mycophenolate mofetil, and itraconazole were all independent clinical predictors of early postoperative infection after HT.

Drug-refractory electrical storm (ES) is a life-threatening medical emergency. We describe the use of venoarterial extracorporeal membrane oxygenation (VA-ECMO) in drug-refractory ES without a ...reversible trigger, for which specific guideline recommendations are still lacking.
Retrospective observational study in four Iberian centres on the indications, treatment, complications, and outcome of drug-refractory ES not associated with acute coronary syndromes, decompensated heart failure, drug toxicity, electrolyte disturbances, endocrine emergencies, concomitant acute illness with fever, or poor compliance with anti-arrhythmic drugs, requiring VA-ECMO for circulatory support. Thirty-four (6%) out of 552 patients with VA-ECMO for cardiogenic shock were included 71% men; 57 (44-62) years, 65% underwent cardiopulmonary resuscitation before VA-ECMO implantation, and 26% during cannulation. Left ventricular unloading during VA-ECMO was used in 8 (24%) patients: 3 (9%) with intraaortic balloon pump, 3 (9%) with LV vent, and 2 (6%) with Impella. Thirty (88%) had structural heart disease and 8 (24%) had an implantable cardioverter-defibrillator. The drug-refractory ES was mostly due to monomorphic ventricular tachycardia (VT) and ventricular fibrillation (VF) (59%), isolated monomorphic VT (26%), polymorphic VT (9%), or VF (6%). Thirty-one (91%) required deep sedation, 44% overdrive pacing, 36% catheter ablation, and 26% acute autonomic modulation. The main complications were nosocomial infection (47%), bleeding (24%), and limb ischaemia (21%). Eighteen (53%) were weaned from VA-ECMO, and 29% had heart transplantation. Twenty-seven (79%) survived to hospital discharge (48 (33-82) days). Non-survivors were older 62 (58-67) vs. 54 (43-58); P < 0.01 and had a higher first rhythm disorder-to-ECMO interval 0 (0-2) vs. 2 (1-11) days; P = 0.02. Seven (20%) had rehospitalization during follow-up 29 (12-48) months, with ES recurrence in 6%.
VA-ECMO bridged drug-refractory ES without a reversible trigger with a high success rate. This required prolonged hospital stays and coordination between the ECMO centre, the electrophysiology laboratory, and the heart transplant programme.

Abstract
Aims
Many historical and recent reports showed that post-infarction ventricular septal rupture (VSR) represents a life-threatening condition and the strategy to optimally manage it remains ...undefined. Therefore, disparate treatment policies among different centres with variable results are often described. We analysed data from European centres to capture the current clinical practice in VSR management.
Methods and results
Thirty-nine centres belonging to eight European countries participated in a survey, filling a digital form of 38 questions from April to October 2022, to collect information about all the aspects of VSR treatment. Most centres encounter 1–5 VSR cases/year. Surgery remains the treatment of choice over percutaneous closure (71.8% vs. 28.2%). A delayed repair represents the preferred approach (87.2%). Haemodynamic conditions influence the management in almost all centres, although some try to achieve patients stabilization and delayed surgery even in cardiogenic shock. Although 33.3% of centres do not perform coronarography in unstable patients, revascularization approaches are widely variable. Most centres adopt mechanical circulatory support (MCS), mostly extracorporeal membrane oxygenation, especially pre-operatively to stabilize patients and achieve delayed repair. Post-operatively, such MCS are more often adopted in patients with ventricular dysfunction.
Conclusion
In real-life, delayed surgery, regardless of the haemodynamic conditions, is the preferred strategy for VSR management in Europe. Extracorporeal membrane oxygenation is becoming the most frequently adopted MCS as bridge-to-operation. This survey provides a useful background to develop dedicated, prospective studies to strengthen the current evidence on VSR treatment and to help improving its currently unsatisfactory outcomes.
Resumen Los seudoaneurismas de aorta ascendente son complicaciones posquirúrgicas infrecuentes, pero extremadamente letales. Su reparación supone un reto quirúrgico debido fundamentalmente al elevado ...riesgo de rotura durante la re-esternotomía y consiguiente exanguinación del paciente, así como a la necesidad de períodos prolongados de parada circulatoria para su reparación. Presentamos una alternativa para el manejo quirúrgico de un gran seudoaneurisma de aorta ascendente, complicado con datos de rotura inminente y hemoptisis severa 6 meses tras una cirugía de sustitución valvular aórtica.

Our aim was to assess the prognostic value of the INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) scale in patients undergoing urgent heart transplantation (HT).
...Retrospective analysis of 111 patients treated with urgent HT at our institution from April, 1991 to October, 2009. Patients were retrospectively assigned to three levels of the INTERMACS scale according to their clinical status before HT.
Patients at the INTERMACS 1 level (n=31) more frequently had ischemic heart disease (P=.03) and post-cardiothomy shock (P=.02) than patients at the INTERMACS 2 (n=55) and INTERMACS 3-4 (n=25) levels. Patients at the INTERMACS 1 level showed higher preoperative catecolamin doses (P=.001), a higher frequency of use of mechanical ventilation (P<.001), intraaortic balloon (P=.002) and ventricular assist devices (P=.002), and a higher frequency of preoperative infection (P=.015). The INTERMACS 1 group also presented higher central venous pressure (P=.02), AST (P=.002), ALT (P=.006) and serum creatinine (P<.001), and lower hemoglobin (P=.008) and creatinine clearance (P=.001). After HT, patients at the INTERMACS 1 level had a higher incidence of primary graft failure (P=.03) and postoperative need for renal replacement therapy (P=.004), and their long-term survival was lower than patients at the INTERMACS 2 (log rank 5.1, P=.023; HR 3.1, IC 95% 1.1-8.8) and INTERMACS 3-4 level (log rank 6.1, p=0.013; HR 6.8, IC 95% 1.2-39.1).
Our results suggest that the INTERMACS scale may be a useful tool to stratify postoperative prognosis after urgent HT.
El uso de dispositivos de asistencia circulatoria mecánica de corta duración como puente a trasplante es frecuente en España. Se desconocen la epidemiología y la repercusión de las complicaciones ...infecciosas en estos pacientes.
Descripción sistemática de la epidemiología y análisis de la repercusión pronóstica de las complicaciones infecciosas en un registro multicéntrico retrospectivo de pacientes tratados con dispositivos de asistencia circulatoria mecánica de corta duración como puente a trasplante cardiaco urgente entre 2010 y 2015 en 16 hospitales españoles.
Se estudió a 249 pacientes; 87 (34,9%) de ellos tuvieron un total de 102 infecciones. La vía respiratoria fue la localización más frecuente (n=47; 46,1%). En 78 casos (76,5%) se obtuvo confirmación microbiológica; se aislaron en total 100 gérmenes causales, con predominio de bacterias gramnegativas (n=58, 58%). Los pacientes con complicaciones infecciosas presentaron mayor mortalidad durante el periodo de asistencia circulatoria mecánica (el 25,3 frente al 12,3%; p=0,009) y menor probabilidad de recibir un trasplante (el 73,6 frente al 85,2%; p=0,025) que los pacientes sin infección. La mortalidad posoperatoria tras el trasplante fue similar en ambos grupos (con infección, el 28,3%; sin infección, el 23,4%; p=0,471).
Los pacientes tratados con dispositivos de asistencia circulatoria mecánica de corta duración como puente al trasplante cardiaco están expuestos a un alto riesgo de complicaciones infecciosas, las cuales se asocian con una mayor mortalidad en espera del órgano.
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.
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.
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%). Microbiological confirmation was obtained in 78 (76.5%) episodes, with a total of 100 causative agents, showing a predominance of gram-negative bacteria (n=58, 58%). Compared with patients without infection, those with infectious complications showed higher mortality during the support period (25.3% vs 12.3%, P=.009) and a lower probability of receiving a transplant (73.6% vs 85.2%, P=.025). In-hospital posttransplant mortality was similar in the 2 groups (with infection: 28.3%; without infection: 23.4%; P=.471).
Patients supported with temporary devices as a bridge to heart transplant are exposed to a high risk of infectious complications, which are associated with higher mortality during the organ waiting period.
Pese a los esfuerzos realizados para mejorar la atención al shock cardiogénico (SC), incluyendo el desarrollo de dispositivos de asistencia circulatoria mecánica (ACM), su pronóstico continúa siendo ...desfavorable. En este contexto surgen iniciativas de código SC, basadas en proporcionar una asistencia rápida y de calidad a estos pacientes. Este documento multidisciplinario trata de justificar la necesidad de implantar el código SC, definiendo su estructura/organización, criterios de activación, flujo de pacientes según nivel asistencial e indicadores de calidad. Sus propósitos concretos son: a) presentar las peculiaridades de esta enfermedad y el aprendizaje del código infarto y de experiencias previas en SC; b) detallar las bases para el abordaje de estos pacientes, la estructura de los equipos, su logística, la elección del tipo de ACM y el momento de su implante, y c) abordar los desafíos para la implantación del código SC, como la singularidad del código SC pediátrico. Urge desarrollar una asistencia protocolizada, multidisciplinaria y centralizada en hospitales con gran volumen y experiencia que permita minimizar la inequidad en el acceso a la ACM y mejorar la supervivencia de estos enfermos. Solo el apoyo institucional y estructural de las distintas administraciones permitirá optimizar la atención al SC.
