Background  Alkaptonuria is a rare autosomal recessive genetic disorder of tyrosine metabolism, which results in accumulation of homogentisic acid in various tissues, including the cardiovascular system. Case Description  We report on a 64-year-old man with mixed aortic valve disease who underwent conventional aortic valve replacement. Intraoperative aortotomy revealed black pigmentation of the intima of the ascending aorta and the aortic valve was observed with thickened and calcified dark black leaflets. Histopathological diagnosis of ochronosis of the aortic valve was made. Conclusion  Despite several previous signs and symptoms, the diagnosis of alkaptonuria was not established until aortic valve replacement.

Background  Pulmonary epithelial-myoepithelial carcinoma (P-EMC) is an extremely rare, well-differentiated, and malignant neoplasm originating from submucosal bronchial glands in the lung. EMCs arise mainly in the salivary glands. Case Description  This case represents an asymptomatic 78-year-old male with a remote 75-pack-year history of smoking who presents with a solitary endobronchial lesion, which is suggestive of a primary lung EMC, detected on annual screening chest computed tomography (CT) scan. Conclusion  A recent review of literature reveals less than 50 documented cases of the pulmonary subtype of this tumor worldwide. We are reporting a unique case of robot-assisted pulmonary lobectomy for a P-EMC.

Transcatheter aortic valve-in-valve implantation (VIV) is increasingly being used to successfully treat degenerated surgical aortic valve bioprostheses (SAVs). The new self-expanding transcatheter heart valve Allegra, from New Valve Technology with its special implantation mechanism, has proven its safety and feasibility for patients with degenerated SAVs, but it has never been used in the latest-generation sutureless SAV. To the best of our knowledge, this is the first description of the successful VIV of the Allegra prosthesis into a degenerated sutureless SAV, and the procedure yielded an excellent postinterventional hemodynamic results.

An anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart disease. Among the variants, an anomalous origin of the left anterior descending coronary artery from the pulmonary artery (ALADPA) is extremely rare. Here, we report a case of ALADPA in an adult that was treated with coronary artery bypass grafting using the left internal thoracic artery.

Background  Pregnancy-associated acute myeloid leukemia (PA-AML) is rare. Cardiac surgery in the context of AML poses challenges that are seldom encountered. Case Description  The subject is a 31-year-old woman at 38 weeks' gestational age diagnosed with AML and partial atrioventricular septal defect. After multidisciplinary consulting, an urgent cesarean section was performed, then chemotherapy was initiated, followed by minimally invasive cardiac surgery with an uneventful recovery. Conclusion  Efficient multidisciplinary approach is essential in the management of PA-AML and cardiac disease. Minimally invasive cardiac surgery may be safe and useful in patients with AML.

The Swiss Society of Cardiac Surgery (SGHC) has announced a "Special Swiss Young Cardiac Surgeon Award 2020," with the aim to learn more about the consequences of the coronavirus disease 2019 (COVID-19) pandemic for young Swiss cardiac surgeons. Therefore, the overall goal of this article is to highlight the personal situation and perspective of a young Swiss cardiac surgeon in training during the COVID-19 pandemic. This article reflects the personal opinion of a young Swiss cardiac surgeon discussing the impact of the pandemic for young surgeons in training and potential chances and learning effects.
