BACKGROUND: Pancreatitis is a serious complication after cardiac surgery and can lead to significant morbidities and mortality. The incidence of pancreatitis is even higher in patients undergoing heart transplantation than in those undergoing other cardiac surgeries. Nevertheless, the clinical presentations of pancreatitis are frequently atypical in these patients. CASE PRESENTATION: We report a heart recipient who was complicated with acute right heart failure initially after orthotopic heart transplantation and developed devastating unanticipated hemorrhagic pancreatitis 1 month after the transplantation...

BACKGROUND: Patients with severely reduced left-ventricular ejection fraction carry a high risk of morbidity and mortality after cardiac surgery. Levosimendan can be used prophylactically in these patients having shown positive effects on short-term outcome. However, effects on long-term outcome and patient subgroups benefiting the most are unknown. We aim to address these topics with real-life data from our clinical practice. METHODS: Two hundred eigthy eight patients with preoperative LVEF ≤ 35% underwent cardiac surgery with cardiopulmonary bypass between 2009 and 2013...

BACKGROUND: Thousands of babies are born with congenital heart defects that require surgical repair involving a prosthetic implant. Lack of growth in prosthetic grafts is especially detrimental in pediatric surgery. Cell seeded biodegradable tissue engineered grafts are a novel solution to this problem. The purpose of the present study is to evaluate the feasibility of seeding human induced pluripotent stem cell derived cardiomyocytes (hiPS-CMs) onto a biodegradable cardiac patch. METHODS: The hiPS-CMs were cultured on a biodegradable patch composed of a polyglycolic acid (PGA) and a 50:50 poly (l-lactic-co-ε-caprolactone) copolymer (PLCL) for 1 week...

BACKGROUND: Aortic valve insufficiency (AI) at the time of left ventricular assist device (LVAD) insertion needs to be corrected, however there is little known about how to manage bioprosthetic valvular AI. CASE PRESENTATION: A 55-year-old female with dilated cardiomyopathy who previously had a bioprosthetic aortic valve replacement needed a LVAD as a bridge to transplant. Her left ventricular ejection fraction was 10% and had mild to moderate transvalvular AI. She underwent a HeartWare HVAD insertion along with aortic valvular coaptation stitch repair (Park's stitch) to the bioprosthetic valve...

BACKGROUND: Transapical approach (TA) is an established access alternative to the transfemoral technique in patients undergoing transcatheter aortic valve replacement (TAVR) for treatment of symptomatic aortic valve stenosis. The impact of prior coronary artery bypass grafting (CABG) on clinical outcomes in patients undergoing TA-TAVR is not well defined. METHODS: A single center retrospective cohort analysis of 126 patients (male 41%, mean age 85.8 ± 6.1 years) who underwent TA balloon expandable TAVR (Edwards SAPIEN, SAPIEN XT or SAPIEN 3) was performed...

OBJECTIVE: Transcatheter aortic valve implantation (TAVI) has been adopted rapidly in Europe. TAVI national registries can augment understanding of technologies and represent real-world experience, providing further clinical insights. We undertook a meta-analysis of published European national TAVI registries to assess current results following TAVI in Europe. METHODS: Electronic databases were searched. The review focused on the comparison of the following TAVI strategies: transfemoral (TF) and transapical (TA) SAPIEN and CoreValve implantation...

BACKGROUND: Coronary artery bypass grafting (CABG) with a composite Y-graft made of the left internal thoracic artery (LITA) and another arterial graft has a risk for hypoperfusion. Changes over time in the diameter of the LITA anastomosed to the left anterior descending coronary artery (LAD) are not known. METHODS: Data were collected for 71 patients who had undergone coronary angiography (CAG) immediately and at 1 year following off-pump CABG with a composite Y-graft made of the LITA and either the radial artery or the right gastroepiploic artery...

BACKGROUND: Intra-aortic balloon pumping (IABP) markedly increases graft flow after coronary artery bypass grafting (CABG) with cardiopulmonary bypass. We sought to delineate the effects of IABP on graft flow after off-pump CABG (OPCAB). METHODS: The clinical records of 32 patients (25 male, 7 female; mean age: 70 ± 9 years) who underwent OPCAB with IABP between January 2011 and May 2015 were retrospectively reviewed. Thirteen patients (41%) had a history of myocardial infarction, and 13 patients (41%) had a history of percutaneous coronary intervention...

BACKGROUND: A low plasma glutamine level was found in 34% of patients after elective cardiothoracic surgery. This could be a result of the inflammation caused by surgical stress or the use of extracorporeal circulation (ECC). But it is also possible that plasma glutamine levels were already lowered before surgery and reflect an impaired metabolic state and a higher likelihood to develop complications. In the present study plasma glutamine levels were measured before and after cardiac surgery and we questioned whether there is a relation between plasma glutamine levels and duration of ECC and the occurrence of postoperative infections...

BACKGROUND: Video-assisted thoracoscopy is become a widely accepted approach for the resection of anterior mediastinal masses, including thymoma. The current trend is to reduce the number of ports and minimize the length of incisions to further decrease postoperative pain, chest wall paresthesia, and length of hospitalization. Herein, we reported an extended resection of thymoma in a patient with myasthenia gravis through an uniportal bilateral thoracoscopic approach. CASE PRESENTATION: A 74 years old woman with myasthenia gravis was referred to our attention for management of a 3...

We reported 3 years ago the use of cryoablation in the treatment of a right atrium myxoma arising from the Koch's triangle. The atrioventricular conduction was successfully preserved. Today, after 3 years follow-up, the patient remains with a conducted sinus rhythm and is free of recurrence. Even if extensive resection of the stack of the myxoma remains the first choice attitude, cryoablation could be considered as a serious second choice alternative.

LETTER
Weizhi Zhang, Lei Gao, Yifeng Yang, Tianli Zhao
We describe a novel minimally invasive technique, transapical transcatheter device closure of relapse left ventricular diverticulum (LVD) under transesophageal echocardiography (TEE) guidance. The patient previously underwent LVD primary repair and mitral valvular replacement. The anatomical characteristics of the relapse LVD and its adjacent structures are detailedly delineated by echocardiography. The relapse LVD is then managed by transapical transcatheter device closure under TEE guidance. This novel minimally invasive technique is not only limited in relapse LVD, but also could be extensively applied in other cardiac reoperation, such as perivalvular leak closure after valvular replacement...

BACKGROUND: Refractory post-cardiotomy cardiogenic shock (PCCS) is a relatively rare phenomenon that can lead to rapid multi-organ dysfunction syndrome and is almost invariably fatal without advanced mechanical circulatory support (AMCS), namely extra-corporeal membrane oxygenation (ECMO) or ventricular assist devices (VAD). In this multicentre observational study we retrospectively analyzed the outcomes of salvage venoarterial ECMO (VA ECMO) and VAD for refractory PCCS in the 3 adult cardiothoracic surgery centres in Scotland over a 20-year period...

BACKGROUND: The association between the anatomy of a single coronary artery (SCA) and the surgical risk of aortic valve replacement (AVR) remains unclear due to a lack of studies on this topic. CASE PRESENTATION: A 73-year-old woman underwent AVR for aortic stenosis. Preoperative coronary angiography results showed a SCA arising from the left coronary sinus. The Manouguian procedure was performed for a small aortic annulus. Intraoperatively, an extracorporeal membrane oxygenator (ECMO) was needed for bypass weaning failure due to newly developed right ventricular dysfunction...

BACKGROUND: Albumin-glutaraldehyde glue has gained widespread acceptance for treatment of alveolar air leaks (AAL) in thoracic surgery. As liquid run-off during application is detrimental to its sealing efficacy, we developed a modified technique and assessed it in vitro. METHODS: Caudal lobes of freshly excised swine lungs (n = 20) were intubated and ventilated. A standardized focal superficial parenchymal defect (40 × 25 mm) was created on the inflated lung...
