BACKGROUND: Aortic stenosis is the most common valvular disease and has a dismal prognosis without surgical treatment. The aim of this meta-analysis was to quantitatively assess the comparative effectiveness of the Perceval (LivaNova) valve versus conventional aortic bioprostheses. METHODS AND RESULTS: A total of 6 comparative studies were identified, including 639 and 760 patients who underwent, respectively, aortic valve replacement with the Perceval sutureless valve (P group) and with a conventional bioprosthesis (C group)...

BACKGROUND: Intrathoracic paragangliomas (PGLs) are rare tumors. Approximately 50% originate from and around cardiac structures. METHODS: A retrospective review was made of the perioperative course of patients with intrathoracic PGL resection from 2000 through 2015 at Mayo Clinic in Rochester, Minnesota. RESULTS: Twenty-two patients underwent PGL resection. Sixteen patients (73%) had functioning tumors (11, noradrenergic; 4, mixed noradrenergic and dopaminergic; 1, dopaminergic)...

OBJECTIVES: Conventional cardiopulmonary bypass is the most commonly used means of artificial circulation in cardiac surgery. However, it suffers from the effects of haemodilution and activation of inflammatory/coagulation cascades. Prime displacement (PD) can offset haemodilution and Mini-Extracorporeal Technology (MIECT) can offset both. So far, no study has compared all of these modalities together; hence, we compared the outcomes of these 3 modalities at our institution. METHODS: This was a retrospective analysis of our cardiac surgical database...

OBJECTIVES: In recent years, the use of del Nido (DN) cardioplegia has been reported in single-valve surgery or isolated coronary artery bypass surgery with acceptable outcomes. The reports of its use in more complex adult cardiac procedures, however, have been scarce. METHODS: We enrolled a total of 149 adult patients who underwent heart valve surgery with the use of DN cardioplegia between May 2014 and December 2016. For a benchmark comparison, 892 patients who underwent cardiac valve surgery with blood cardioplegia during the same period served as controls...

BACKGROUND: Coronary artery bypass grafting (CABG) combined with coronary endarterectomy (CE) can be associated with high operative mortality and morbidity. An intra-aortic balloon pump (IABP) has been the most widely used mechanical circulatory support device during perfusion treatment. However, the benefits of preoperative IABP in CABG combined with CE remain unknown. We conducted a retrospective observational study to evaluate the efficacy of preoperative IABP therapy in patients undergoing adjunctive right coronary artery (RCA) endarterectomy...

Introduction Myocardial protection is vital to ensure successful open heart surgery. Cardioplegic solution is one method to achieve good myocardial protection. Inevitably, ischemia-reperfusion injury occurs with aortic crossclamping. Histidine-tryptophan-ketoglutarate solution is a frequently used cardioplegia for complex congenital heart surgery. We postulated that addition of terminal warm blood cardioplegia before removal of the aortic crossclamp might improve myocardial protection. Method A randomized controlled trial was conducted on 109 cyanotic patients aged, 1 to 5 years who underwent complex biventricular repair...

OBJECTIVES: During open-heart surgery, the myocardium experiences ischaemia-reperfusion injury. A single bout of moderate, 30-min exercise induces preconditioning and protects the heart from ischaemia-reperfusion injury in rats, but this has never been investigated in humans. We aimed to investigate whether 1 bout of moderate exercise 24 h prior to surgery protects against mitochondrial and cardiac damage. METHODS: Patients scheduled for elective coronary artery bypass were eligible for this pilot study...

BACKGROUND: In this study, we describe the technique of eversion of the native aortic tissue to prevent suture line complications, and report on our results with this technique. METHODS: A total of 42 patients who were operated on due to aortic aneurysm were retrospectively assessed. In all patients, an aortic segment of approximately 2 cm, which was left both distally and proximally, was everted to form a double-layer lumen and the grafts were anastomosed. Postoperative outcomes and long-term follow-up results were assessed...

REVIEW
Sang-Bae Ko
Although perioperative stroke is uncommon during low-risk non-vascular surgery, if it occurs, it can negatively impact recovery from the surgery and functional outcome. Based on the Society for Neuroscience in Anesthesiology and Critical Care Consensus Statement, perioperative stroke includes intraoperative stroke, as well as postoperative stroke developing within 30 days after surgery. Factors related to perioperative stroke include age, sex, a history of stroke or transient ischemic attack, cardiac surgery (aortic surgery, mitral valve surgery, or coronary artery bypass graft surgery), and neurosurgery (external carotid-internal carotid bypass surgery, carotid endarterectomy, or aneurysm clipping)...

OBJECTIVE: Teaching the next generation operative cardiac surgery while maintaining the highest level of patient care is an ever-increasing challenge given the growing proportion of patients with multiple comorbidities, the loss of more straightforward cases to percutaneous interventions, and the pressure of public reporting. No study to date has compared the outcomes of similar cases performed entirely ("skin-to-skin") by the resident with those performed entirely by the staff to confirm the safety of this practice...

Injuries of the supra-aortic trunk after blunt chest trauma are rare. This is a case report of a blunt traumatic lesion of the innominate artery (IA) origin that exhibited aortic arch involvement with a focus on imaging and treatment. A 41-year-old fisherman presented an IA injury secondary to a high-impact blunt chest trauma. Upon physical examination, vital signs were stable and upper extremity pulses were present. In addition to several bone fractures (costal ribs, clavicle, scapula, temporal, maxillary, and sphenoid), computed tomography angiography revealed dissection/pseudoaneurysm of the IA sparing the bifurcation...

Total aortic arch replacement remains a technically formidable procedure, particularly in patients with previous proximal aortic dissection repair. Our case discussion highlights a useful strategy for extracorporeal support and circulation management to facilitate total arch reconstruction in the reoperative setting, based on cannulation of the left axillary artery. Our preference is to use a left axillary artery approach to initiate cardiopulmonary bypass and to ultimately revascularize the left arm via an extra-anatomic graft...

BACKGROUND: Acute kidney injury (AKI) is a common serious complication following cardiac surgery. Doppler-determined renal resistive index (RRI) is a promising early AKI biomarker in this population. However, the relationship between aortic valve pathology (insufficiency and/or stenosis) and RRI is unknown. This study aimed to investigate RRI variability related to aortic valve pathology. METHODS: In a retrospective review of cardiac surgery patients, RRI and aortic valve pathology were assessed prior to cardiopulmonary bypass using transesophageal echocardiography...
