RESUMEN
This is a case report of a 78-year-old male who underwent a sub-coronary aortic valve and root replacement due to valve dehiscence and aortic root pseudoaneurysm. The patient had complex anomalous coronary anatomy and had undergone a previous tissue aortic valve replacement in 2013. The patient made an uneventful recovery and was discharged from the hospital five days later. The authors suggest that the sub-coronary root replacement technique should be considered in elderly patients and patients with complex coronary anatomy.

BACKGROUND: There is increasing evidence to suggest vitamin D plays a role in immune and vascular function; hence, it may be of biological and clinical relevance for patients undergoing major surgery. With a greater number of randomised studies being conducted evaluating the impact of vitamin D supplementation on surgical patients, it is an opportune time to conduct further analysis of the impact of vitamin D on surgical outcomes. METHODS: MEDLINE, EMBASE and the Cochrane Trials Register were interrogated up to December 2023 to identify randomised controlled trials of vitamin D supplementation in surgery. The risk of bias in the included studies was assessed using the Cochrane Risk of Bias tool. A narrative synthesis was conducted for all studies. The primary outcome assessed was overall postoperative survival. RESULTS: We screened 4883 unique studies, assessed 236 full-text articles and included 14 articles in the qualitative synthesis, comprising 1982 patients. The included studies were highly heterogeneous with respect to patient conditions, ranging from open heart surgery to cancer operations to orthopaedic conditions, and also with respect to the timing and equivalent daily dose of vitamin D supplementation (range: 0.5-7500 mcg; 20-300 000 IU). No studies reported significant differences in overall survival or postoperative mortality with vitamin D supplementation. There was also no clear evidence of benefit with respect to overall or intensive care unit length of stay. DISCUSSION: Numerous studies have reported the benefits of vitamin D supplementation in different surgical settings without any consistency. However, this systematic review found no clear evidence of benefit, which warrants the supposition that a single biological effect of vitamin D supplementation does not exist. The observed improvement in outcomes in low vitamin D groups has not been convincingly proven beyond chance findings. TRIAL REGISTRATION NUMBER: CRD42021232067.

Aberrant origin of coronary artery is a rare congenital anomaly associated with increased risk of myocardial ischemia and sudden death, with the highest risk lesions being those arising from the opposite sinus of Valsalva. We report a case with an aberrant right coronary artery arising superior to the left coronary cusp, with a slit-like ostium, having an inter-arterial and intramural course through the aortic root, that underwent repositioning of the right coronary artery. We believe such cases warrant surgical correction and reimplantation is a safe, effective and reproducible technique.

BACKGROUND: Mycotic pseudoaneurysms of the ascending aorta are a rare and devastating complication of previous cardiac surgery. CASE PRESENTATION: We present an unusual case of a fungal mycotic pseudoaneurysm secondary to an aortic suture line successfully repaired under deep hypothermic circulatory arrest. CONCLUSIONS: Patients with mycotic pseudoaneurysms of the aorta require a multidisciplinary team approach to prevent devastating complications that may occur in these complex surgical cases.

BACKGROUND: Bronchopulmonary sequestration (BPS) is a malformation of the lungs resulting in lung tissue lacking direct communication to the tracheobronchial tree. Most cases demonstrate systemic arterial blood supply from the descending thoracic aorta, the abdominal aorta, celiac axis or splenic artery and venous drainage via the pulmonary veins with occasional drainage into azygos vein. BPS is considered a childhood disease and accounts for 0.15-6.40% of congenital pulmonary malformations. BPS is divided into intralobar sequestrations (ILS) and extralobar sequestrations (ELS) with ILS accounting for 75% of all cases. METHODS: Here we present our 11-year experience of dealing with BPS; all cases presented with recurrent chest sepsis in young-late adulthood regardless of the type of pathological sequestration. The surgical technique employed was a minimally invasive video-assisted thoracoscopic anterior approach (VATS). RESULTS: Between May 2010 and September 2021, we have operated on nine adult patients with bronchopulmonary sequestration who presented late with symptoms of recurrent chest sepsis. Most patients in the cohort had lower lobe pathology, with a roughly even split between right and left sided pathology. Moreover, the majority were life-long never smokers and an equal preponderance in males and females. The majority were extralobar sequestrations (56%) with pathological features in keeping with extensive bronchopneumonia and bronchiectasis. There were no major intra-operative or indeed post-operative complications. Median length of stay was 3 days. CONCLUSIONS: Dissection and division of the systemic feeding vessel was readily achievable through a successful anterior VATS approach, regardless of the type of sequestration and without the use of pre-operative coiling of embolization techniques. This approach gave excellent access to the hilar structures yet in this pathology, judicious and perhaps a lower threshold for open approach should be considered.

Thrombotic thrombocytopenic purpura (TTP) is a life-threatening disorder involving thrombotic microangiopathy and is characterized by increased platelet aggregation throughout the body. Acquired TTP can be triggered by a variety of conditions including infections. We hereby describe a case report of an 81-year-old female presenting to the internal medicine department with TTP and active chronic gastritis, positive for Helicobacter pylori (H. pylori) on biopsy. The TTP was highly resistant to medical therapy; however the patient underwent complete resolution of her TTP following H. pylori eradication. We conclude that acquired TTP may be triggered by H. pylori infection and that treating the underlying infection may play a role in improving TTP's outcome in some patients, especially when disease is refractory to medical therapy.
