With improved outcomes following cardiac surgery, health related quality of life (HRQoL) gains increasing importance for the better judgement of choosing the preferred treatment strategy in the individual patient. The physician perception of patient preferences can differ considerably from actual patient preferences, underlining the importance of gathering evidence of actual patient preferences before and quality of life after cardiac surgery. The objective of the current review is to provide an overview of current insights into the quality of life measurements after aortic valve and thoracic aortic surgery and to provide starting points for the application of HRQoL measurements toward the future...

BACKGROUND: Mechanical chest compression using a piston device during reanimation is often the only way to ensure stable chest compression at a constant rate and force. However, its use can be associated with severe fractures of the thoracic rib cage and endanger the clinical course of the patient. Thus, the usage of such a piston device during the reanimation has currently been classified as a mere Class IIB indication. CASE PRESENTATION: We present a case of a 66-year-old male who underwent emergent CABG surgery after receiving out-of-hospital resuscitation as a result of myocardial infarction using the LUCAS system...

OBJECTIVE: Mediastinal radiation therapy (MRT) increases the risk for adverse outcomes after cardiac surgery and is not incorporated in the Society of Thoracic Surgeons (STS) risk algorithm. We aimed to quantify the surgical risk conferred by MRT in patients undergoing primary and reoperative valvular operations. METHODS: A retrospective analysis of 261 consecutive patients with prior MRT who underwent valvular operations between January 2002 and May 2015. Short- and long-term outcomes were compared for STS predicted risk of mortality, surgery type, gender, year of surgery, and age-matched patients stratified by reoperative status...

BACKGROUND: Surgery confers the best chance of survival following acute Type A dissection (ATAD), yet perioperative mortality remains high. Although perioperative risk factors for mortality have been described, information on the actual causes of death is sparse. In this study, we aimed to characterize the inciting events causing death during surgical repair of ATAD. METHODS: Nine centers participated in the study. We included all patients who died following surgical repair for ATAD between January 2007 and December 2013...

CASE DESCRIPTION 2 dogs with chylothorax were identified to have cardiac mass lesions obstructing the return of venous blood from the cranial vena cava. Chylous effusion was presumed to have been a result of an increase in cranial vena cava pressure affecting flow of chyle through the thoracic duct. CLINICAL FINDINGS Both dogs had tachypnea and pleural effusion requiring therapeutic thoracocentesis. Fluid analysis confirmed chylothorax. A heart-base mass was identified via echocardiography in each dog, and CT-angiographic findings confirmed obstruction to venous return in the cranial vena cava in both dogs and compression of the pulmonary artery in 1 dog...

In patients undergoing cardiac surgery, use of perioperative screening for aortic atherosclerosis with modified TEE (A-View method) was associated with lower postoperative mortality, but not stroke, as compared to patients operated on without such screening. At the time of clinical implementation and validation, we did not yet standardize the indications for modified TEE and the changes in patient management in the presence of aortic atherosclerosis. Therefore, we designed a protocol, which combined the diagnosis of atherosclerosis of thoracic aorta and the subsequent considerations with respect to the intraoperative management and provides a systematic approach to reduce the risk of cerebral complications...

OBJECTIVE: Retrograde cerebral perfusion (RCP) is a brain protection technique that is adopted generally for anticipated short periods of deep hypothermic circulatory arrest (DHCA). However, the real impact of this technique on cerebral protection during DHCA remains a controversial issue. METHODS: For 344 (59.5%) of 578 consecutive patients (mean age, 66.9 ± 10.9 years) who underwent cardiovascular surgery under DHCA at the present authors' institution (1999-2015), RCP was the sole technique of cerebral protection that was adopted in addition to deep hypothermia...

BACKGROUND: Acute kidney injury (AKI) and its severity after transcatheter aortic valve replacement (TAVR) have been associated with worse outcomes. Studies have shown that AKI duration (transient or persistent) affects outcomes independently of AKI severity. This study was undertaken to determine the association, risk factors, and outcomes associated with persistent AKI (pAKI) after TAVR. METHODS: Adult patients undergoing TAVR at Mayo Clinic between January 1, 2008 and June 30, 2014 were enrolled...
