"Martin Mattress": Surgical Technique for Achieving Hemostasis in Redo Aortic Root Operations.

A 71-year-old gentleman with prior bioprosthetic aortic valve replacement was admitted with aortic valve dehiscence and an aortic root abscess. He underwent reoperative sternotomy, aortic root, mitral valve, and hemiarch replacement. To augment hemostasis, we implanted the "Martin Mattress"-a pericardial patch sutured to the fibrous ridge within the innominate vein, superior vena cava, right atrium, right ventricular outflow tract, and pulmonary artery-which is preferred to modified Cabrol fistula techniques in infectious root pathology.

Contemporary Bridge to Heart Transplantation With Venoarterial Extracorporeal Membrane Oxygenation.

In October 2018, the United Network for Organ Sharing changed their heart allocation criteria to prioritize patients on temporary mechanical circulatory support. This study assesses outcomes of patients bridged to orthotopic heart transplantation (OHT) with venoarterial extracorporeal membrane oxygenation (VA ECMO) since this change. We conducted a retrospective single-center study of adults (≥18 years) supported with VA ECMO at the time of OHT (October 1, 2018, to December 31, 2021).

Objective: Impella 5.5 (Abiomed, Danvers, MA, USA) is a temporary mechanical circulatory support device used for patients in cardiogenic shock. This review provides a comprehensive overview of the device's clinical effectiveness, safety profile, patient outcomes, and relevant procedural considerations.

Successful Extracorporeal Cardiopulmonary Resuscitation Despite Aortic Occlusion.

We present the case of a 62-year-old man with severe coronary artery disease who presented to the hospital in refractory ventricular fibrillation cardiac arrest. He showed signs of life despite prolonged resuscitation. We thus decided to initiate extracorporeal cardiopulmonary resuscitation (ECPR).

Temporary mechanical support in the peripartum patient as a bridge to postpartum recovery: A report of three cases.

Cardiogenic shock (CS) is a severe complication of peripartum cardiomyopathy (PPCM). Patients with deteriorating CS often require temporary mechanical circulatory support. In PPCM, this can be used as a bridge to postpartum recovery or bridge to decision.

PREDICT HF: Risk stratification in advanced heart failure using novel hemodynamic parameters.

Background: Invasive hemodynamics are fundamental in assessing patients with advanced heart failure (HF). Several novel hemodynamic parameters have been studied; however, the relative prognostic potential remains ill-defined.

Hypothesis: Advanced hemodynamic parameters provide additional prognostication beyond the standard hemodynamic assessment.

Reconsidering FDA Guidelines: A Single-Center Experience of Prolonged Impella 5.5 Support.

Objective: Impella 5.5 (Abiomed, Danvers, MA, USA) is approved by the US Food and Drug Administration (FDA) for mechanical circulatory support for ≤14 days. It is unknown whether prolonged support is associated with worse outcomes.

Perioperative Cerebrospinal Fluid Drain Placement Does Not Increase Venous Thromboembolism Risk After Thoracic and Fenestrated Endovascular Aortic Repair.

Background: Venous thromboembolism (VTE) incidence after thoracic and fenestrated endovascular aortic repair (TEVAR/FEVAR) is high (up to 6-7%) relative to other vascular procedures; however, the etiology for this discrepancy remains unknown. Notably, patients undergoing TEVAR/FEVAR commonly receive cerebrospinal fluid drains (CSFDs) for neuroprotection, requiring interruption of perioperative anticoagulation and prolonged immobility. We hypothesized that CSFDs are a risk factor for VTE after TEVAR/FEVAR.

Preoperative respiratory strength training is feasible and safe and improves pulmonary physiologic capacity in individuals undergoing cardiovascular surgery.

Objective: To determine the safety, feasibility, and physiologic impact of a preoperative respiratory strength training (RST) program in individuals undergoing elective cardiac surgery (CS).

Methods: Twenty-five adults undergoing an elective CS at an academic hospital setting enrolled and completed RST 5 days/week (50 repetitions, 50% training load, ≥3 weeks) at home via telehealth in this open-label prospective cohort study. RST adherence, telehealth attendance, and adverse events were tracked.

Left Ventricular Assist Device Use in Minorities: An Analysis of the National Inpatient Sample.

Minorities are less likely to receive a left ventricular assist device (LVAD). This, however, is based on total implant data. By examining rates of LVAD implant among patients admitted with heart failure complicated by cardiogenic shock, we sought to further elucidate LVAD utilization rates and racial disparities.

Utility of Fiberoptic Endoscopic Evaluation of Swallowing After Left Ventricular Assist Device Implantation.

Objective Dysphagia following cardiac surgery is common and associated with adverse outcomes. Among patients receiving left ventricular assist devices (LVAD), we evaluated the impact of fiberoptic endoscopic evaluation of swallowing (FEES) on outcomes. Methods A single-center pilot study was conducted in adults (≥18 years of age) undergoing durable LVAD (February 2019 - January 2020).

Durable biventricular assist device support for 1212 days as a bridge to heart transplantation.

Experience with durable biventricular assist devices (BiVADs) as a bridge to heart transplantation (HTx) is limited, particularly in women. A 41-year-old woman with biventricular failure complicated by cardiogenic shock underwent durable concurrent BiVAD implantation and was supported for 1212 days as a bridge to HTx. During BiVAD support, she experienced bacteremia (day 1030 of support), appropriately managed with intravenous antibiotics.

Provision of Oral Care in the Cardiothoracic Intensive Care Unit: Survey of Nursing Staff Training, Confidence, Methods, Attitudes, and Perceived Barriers.

Background: Poor oral health is associated with adverse outcomes in critical care settings. Although provision of oral care is a fundamental aspect of nursing practice, both formal training and practice among nursing staff remain unclear.

Method: Cardiothoracic intensive care unit nurses were recruited to complete a 16-item survey regarding training, confidence, methods, prioritization, and barriers to provision of oral care.

Utilization of the percutaneous left ventricular support as bridge to heart transplantation across the United States: In-depth UNOS database analysis.

Background: Intra-aortic balloon pump (IABP) and Impella device utilization as a bridge to heart transplantation (HTx) have risen exponentially. We aimed to explore the influence of device selection on HTx outcomes, considering regional practice variation.

Methods: A retrospective longitudinal study was performed on a United Network for Organ Sharing (UNOS) registry dataset.

Successful extended use of Impella 5.5 as a bridge to heart transplantation.

We present the case of a 60-year-old gentleman who was admitted with acute-on-chronic cardiogenic shock and was supported with axillary Impella 5.5® for 123 days prior to heart transplantation. Total length of temporary mechanical circulatory support (MCS) was 132 days, which included 9 days with an intra-aortic balloon pump prior to Impella.

Intraoperative Hemi-Diaphragm Electrical Stimulation Demonstrates Attenuated Mitochondrial Function without Change in Oxidative Stress in Cardiothoracic Surgery Patients.

Mechanical ventilation during cardiothoracic surgery is life-saving but can lead to ventilator-induced diaphragm dysfunction (VIDD) and prolong ventilator weaning and hospital length of stay. Intraoperative phrenic nerve stimulation may preserve diaphragm force production to offset VIDD; we also investigated changes in mitochondrial function after stimulation. During cardiothoracic surgeries ( = 21), supramaximal, unilateral phrenic nerve stimulation was performed every 30 min for 1 min.

Heparin-based versus bivalirudin-based anticoagulation in pediatric extracorporeal membrane oxygenation: A systematic review.

Introduction: Optimal anticoagulation therapy is essential for the prevention of thrombotic and hemorrhagic complications in pediatric patients supported with extracorporeal membrane oxygenation (ECMO). Recent data have demonstrated bivalirudin has the potential to surpass and replace heparin as the anticoagulant of choice.

Methods: We conducted a systematic review comparing the outcomes of heparin-based versus bivalirudin-based anticoagulation in pediatric patients supported on ECMO to identify the preferred anticoagulant to minimize bleeding events, thrombotic complications, and associated mortality.

Timing and Outcomes of Concurrent and Sequential Biventricular Assist Device Implantation: A Society of Thoracic Surgeons Intermacs Analysis.

Background: Biventricular heart failure remains a clinically challenging condition to manage. Available literature describing the use of durable biventricular assist device (BiVAD) support has numerous limitations hindering the development of useful treatment algorithms. Analysis of BiVAD use within a large multicenter data set is needed to clarify outcomes associated with this therapy.

Caregiver Stress Is Improved and Sustained Following Transcatheter Aortic Valve Replacement.

Background: Little is known about the impact of symptomatic aortic stenosis and subsequent transcatheter aortic valve replacement (TAVR) on stress and health for the caregiver. In this prospective cohort study, we measured caregiver stress before and after TAVR.

Methods: We interviewed 34 primary caregivers for patients undergoing outpatient TAVR at an academic institution.

Prognostic Value of Frailty for Heart Failure Patients Undergoing Left Ventricular Assist Device Implantation: A Systematic Review.

Frailty is associated with poor clinical outcomes in heart failure patients. The impact of frailty on outcomes following left ventricular assist device (LVAD) implantation, however, is less clearly defined. We therefore sought to conduct a systematic review to evaluate current frailty assessment strategies and their significance for patients undergoing LVAD implantation.
