We report a male patient who underwent successful redo cardiac surgery in 2014; tricuspid valve repair and redo mitral valve replacement of a Starr-Edwards mitral valve implanted 48 years previously. Six years after the redo operation, the patient remains well and therefore has an impressive over 54 years of survival following mitral valve replacement surgery.

As the focus of the COVID-19 crisis is gradually taken away from emergency healthcare needs, increased attention is warranted on the psychological impact of the pandemic on a global level. Existing guidance on managing the COVID-19 related distress needs to be better informed by upcoming larger-scale research. Applying e-Health can be useful in dealing with the immediate psychological needs, while developing strategies to identify vulnerable populations and shifting the provision of mental health and social care to community services need to be prioritised when looking at the future.

Late Cardiocutaneous Fistula (CF) is an uncommon but potentially serious postoperative complication of cardiac surgery. We present the successful treatment of a 58-year-old female who developed a CF extending from the left ventricular apex into the left breast related to mitral valve replacement 15 years ago.

A unique case of a patient with Ehlers-Danlos type IV syndrome was referred with aortic root aneurysm and previous cosmetic primary repair of pectus excavatum (PE) through a solid silicone onlay prosthesis. The patient underwent successful removal of the silicone prosthesis and one-stage ascending aortic root replacement with concomitant Nuss procedure for repair of the PE.

There is ongoing scientific interest regarding comorbidities associated with the metabolic syndrome (MeTS). MeTS comprises a combination of parameters that predispose individuals to the development of type 2 diabetes and cardiovascular disease (CVD). Three or more of the following criteria are necessary: fasting glucose > 110 mg/dl (5.

Infraspinatus atrophy (IA) is much more prevalent in overhead sports compared with the general population. Its exact aetiology in this group of athletes remains unclear and definitive associations with pathology and performance have not yet been reached. The aim of this systematic review is to present the evidence on IA in overhead athletes focussing on the proposed mechanisms of suprascapular neuropathy and its associations with shoulder pathology and performance.

In volleyball, the dominant shoulder of the athlete undergoes biomechanical and morphological adaptations; however, definitive conclusions about their exact nature, aetiology, purpose and associations with shoulder injury have not been reached. We present a systematic review of the existing literature describing biomechanical adaptations in the dominant shoulders of volleyball players and factors that may predispose to shoulder pain/injury. A thorough literature search via Medline, EMBASE and SCOPUS was conducted for original studies of volleyball players and 15 eligible articles were identified.

Coronary artery endarterectomy (CE) is a procedure performed adjunctive to coronary artery bypass grafting in patients with diffuse coronary artery disease (CAD). This review was conducted in order to assess the safety of the procedure, the associated complications as well as short- and long-term patient outcomes. A literature search was performed via Pubmed, and 50 articles were included in the review based on our inclusion and exclusion criteria.

The aims of our study were to compare the dominant (DOM) and non-dominant (NDOM) shoulders of high-level volleyball athletes and identify possible associations of shoulder adaptations with spike speed (SS) and shoulder pathology. A total of 22 male volleyball players from two teams participating in the first division of the Cypriot championship underwent clinical shoulder tests and simple measurements around their shoulder girdle joints bilaterally. SS was measured with the use of a sports speed radar.

Atrial fibrillation (AF) is the most common cardiac arrhythmia and a huge public health burden associated with significant morbidity and mortality. For decades an increasing number of patients have undergone surgical treatment of AF, mainly during concomitant cardiac surgery. This has sparked a drive for conducting further studies and researching this field.

Blunt thoracic aortic injuries (BTAIs) present a great challenge because of their potentially fatal outcomes. Recent advancements in their management have proved to be beneficial in terms of various parameters, including mortality and complications. Endovascular repair is now the treatment of choice in most centres and is continuously replacing the traditional open surgical method.

Postoperative deep sternal wound infection (DSWI) is a serious complication in cardiac surgery (1-5% of patients) with high mortality and morbidity rates. Vacuum-assisted closure (VAC) therapy has shown promising results in terms of wound healing process, postoperative hospital length of stay and lower in-hospital costs. The aim of our retrospective study is to report the outcome of patients with DSWI treated with VAC therapy and to assess the effect of contributory risk factors.

Despite the growing body of evidence on the potential effects of calcium and vitamin D as monotherapies on different cardiovascular (CV) parameters, the combined supplementation with calcium and vitamin D (CaD), which is most frequently encountered in clinical practice, has not received the attention it deserves. A literature search was conducted via EMBASE and Medline and identified 14 randomised controlled trials (RCTs) and 2 meta-analyses reporting on effects of combined supplementation with CaD on CV events, CV death, blood pressure, lipids, glucose metabolism and weight. Overall, the existing evidence does not support beneficial properties of supplementation with CaD on the CV system, nor does it suggest that a re-appraisal of the use of CaD is necessary due to adverse effects, although increased risk of CV events has been reported by some authors.

Blunt thoracic aortic injuries, even though rare in incidence, carry significant mortality rates and their management still remains challenging. There have been major shifts in diagnosing and treating these injuries in the last 5 decades, which proved to be beneficial in terms of mortality and complications. Endovascular repair has been increasingly used for definitive treatment and its outcomes appear to be at least equally safe and effective as those of open repair.

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was in osteogenesis imperfecta (OI) patients with valve disease undergoing valve replacement which type of valve (bioprosthetic or mechanical) is most appropriate in terms of safety, complications and survival. Altogether more than 77 papers were found as a result of the reported search, of which 43 represented the best evidence to answer the clinical question.

Pulmonary chondromatous (or chondroid) hamartomas are common benign tumours of the lung and may be either parenchymal or endobronchial. The latter are only rarely encountered and have a variation in their clinical presentation related to the endobronchial obstructive lesion, including atelectasis, pneumonia, hemoptysis. If not diagnosed early and treated properly, endobronchial hamartomas can cause irreversible lung damage.

Coronary artery perforation is a known complication of percutaneous coronary intervention and potentially life threatening. Normally, these perforations are small and localized. We report the successful surgical management of a coronary artery perforation following stent insertion with extrusion of an 8-cm endarterectomy length of the circumflex coronary artery with a brief review of the recent literature.

Osteogenesis imperfecta (OI) is a heritable disorder of the connective tissue. Cardiovascular involvement is rare, related mainly to aortic valve regurgitation. Open-heart surgery in these patients is associated with increased morbidity and mortality rates as a result of tissue friability and bone brittleness as well as platelet dysfunction.
