Echocardiography in the intensive care unit: An essential tool for diagnosis, monitoring and guiding clinical decision-making.

In the last years, new trends on patient diagnosis for admission in cardiac intensive care unit (CICU) have been observed, shifting from acute myocardial infarction or acute heart failure to non-cardiac diseases such as sepsis, acute respiratory failure or acute kidney injury. Moreover, thanks to the advances in scientific knowledge and higher availability, there has been increasing use of positive pressure mechanical ventilation which has its implications on the heart. Therefore, there is a growing need for Cardiac intensivists to quickly, noninvasively and repeatedly evaluate various hemodynamic conditions and the response to therapy. Transthoracic critical care echocardiography (CCE) currently represents an essential tool in CICU, as it is used to evaluate biventricular function and complications following acute coronary syndromes, identify the mechanisms of circulatory failure, acute valvular pathologies, tailoring and titrating intravenous treatment or mechanical circulatory support. This could be completed with trans-esophageal echocardiography (TOE), advanced echocardiography and lung ultrasound to provide a thorough evaluation and monitoring of CICU patients. However, CCE could sometimes be challenging as the acquisition of good-quality images is limited by mechanical ventilation, suboptimal patient position or recent surgery with drains on the chest. Moreover, there are some technical caveats that one should bear in mind while performing CCE in order to optimize its use and avoid misleading findings. The aim of this review is to highlight the key role of CCE, providing an updated overview of its main applications and possible pitfalls in order to facilitate its use in CICU for clinical decision-making.

Percutaneous Impella CP exchange with preservation of transfemoral access.

In patients with cardiogenic shock, the global use of percutaneous mechanical circulatory support using the Impella CP device has increased with early data suggesting potential benefits over conservative management. In the current case report we describe a simple technique facilitating percutaneous Impella CP or RP exchange with preservation of transfemoral access, which does not require the use of a 0.035' wire. This technique allows for percutaneous sealing of the 14F arteriotomy using new closure devices avoiding the traditional cut-down.

Lessons of the month 1: Fatal oesophago-pericardial fistula with cerebral air embolism after elective atrial fibrillation ablation.

Oesophago-pericardial fistula following any electrophysiological procedure is a rare, and potentially, life-threatening condition. Initial presentation can easily be misdiagnosed, as symptoms vary and are not specific. Echocardiography is an invaluable tool to diagnose and rule out complications. We present the case of a 68-year-old patient who developed an oesophago-pericardial fistula complicated with purulent pericarditis, sepsis and cerebral air embolism. In conclusion, this case report encourages physicians to use strategies that may help with early diagnosis and lead to potential lifesaving interventions.

Candidemia persistente en una paciente receptora de trasplante renopancreático / Persistent candidemia in a renal-pancreatic transplant patient

El trasplante de órgano sólido ha presentado un aumento en la supervivencia en las últimas décadas en relación con el perfeccionamiento de la técnica quirúrgica, la protocolización del manejo inmu-nosupresor y el uso de profilaxis antimicrobiana. A pesar de ello, la infección fúngica invasiva (IFI) es la mayor causa de morbimortalidad en este grupo de pacientes. En el trasplante renal, la IFI más frecuente es la candidiasis invasiva, que habitualmente se asocia al empleo de nutrición parenteral total, de tratamiento antibiótico de amplio espectro y a la cirugía abdominal. Caso clínico Presentamos el caso de una paciente con trasplante renopancreático reciente que desarrolla una candidemia persistente asociada a catéter, causada por Candida glabrata, que se trata con anidulafungi-na. Presentó una buena evolución clínica y no se observaron interacciones farmacológicas relevantes. Se discuten las posibles causas y las alternativas diagnóstico-terapéuticas de este tipo de infección(AU)

In recent decades, there has been an increase in the survival of recipients of solid organ trans-plants related to the improvement of the surgical technique, the introduction of protocols for immunosu-ppressive therapy, and the use of antimicrobial prophylaxis. Nonetheless, invasive fungal infection (IFI) is currently the major cause of morbidity and mortality in this group of patients. Invasive candidiasis is the most common IFI found after renal transplantation and is usually associated with total parenteral nutrition, broad-spectrum antibiotic therapy and abdominal surgery. Clinical case. We report the case of a recent kidney-pancreas transplant recipient who developed a persis-tent catheter-related candidemia caused by Candida glabrata. The patient was treated with anidulafungin and had a good clinical course with no significant drug interactions. We discuss the possible causes and diagnostic and therapeutic alternatives of this kind of infection(AU)

BACKGROUND: In recent decades, there has been an increase in the survival of recipients of solid organ transplants related to the improvement of the surgical technique, the introduction of protocols for immunosuppressive therapy, and the use of antimicrobial prophylaxis. Nonetheless, invasive fungal infection (IFI) is currently the major cause of morbidity and mortality in this group of patients. Invasive candidiasis is the most common IFI found after renal transplantation and is usually associated with total parenteral nutrition, broad-spectrum antibiotic therapy and abdominal surgery. CLINICAL CASE: We report the case of a recent kidney-pancreas transplant recipient who developed a persistent catheter-related candidemia caused by Candida glabrata. The patient was treated with anidulafungin and had a good clinical course with no significant drug interactions. We discuss the possible causes and diagnostic and therapeutic alternatives of this kind of infection.
