ABSTRACT
Aortico-left ventricular tunnel is a very rare congenital cardiac anomaly, always arises from the right coronary sinus and enters the left ventricle. However, aortico-left ventricular tunnel associated with Takayasu's arteritis has not been described so far in the literature. Here, we present an unusual case of aortico-left ventricular tunnel associated with Takayasu's arteritis in a 44-year-old man.

BACKGROUND: There are different surgical approaches used for repairing a supracardiac total anomalous pulmonary venous connection (TAPVC), with different results. This retrospective study evaluated the outcomes of surgical repair for supracardiac TAPVC through the combined superior approach in neonatal patients. METHODS: Medical records were retrospectively reviewed and 21 neonates who underwent supracardiac TAPVC repair with the combined superior approach between July 2014 and January 2020 were identified. There were 13 males and eight females. RESULTS: The patients' median age was 20.6±8.9 days (range, 3-27). The median weight was 3.1±0.39 kg (range, 2.5-3.7) The median aortic cross-clamp and cardiopulmonary bypass times were 49.3±19.5 minutes (range, 27-86) and 91.1±23.7 minutes (range, 57-146). They were two deaths during the intensive care unit stay. One (1) patient died 2 months after discharge, the other remaining patients had no pulmonary venous obstruction (PVO) at the 6-month and intermediate-term follow-ups. CONCLUSIONS: The combined superior approach is a useful method for repair of neonatal critical supracardiac TAPVC. This technique may be more helpful in preventing early postoperative anastomotic stenosis and contribute to an improved patient outcome.

Anastomotic pseudoaneurysm remains one of the main life-threatening complications of cardiac and thoracic aorta surgery. We report a rare case of infected pseudoaneurysm at the anastomotic line found during follow-up. Blood culture results suggested Enterococcus faecium infection. Transthoracic echocardiography and computed tomography scans revealed the presence of a pseudoaneurysm of the ascending aorta. The pseudoaneurysm was resected and the ascending aorta was reconstructed with an artificial vascular patch without complications. Reducing the anastomotic tension, with complete hemostasis at the anastomotic incision, is the most important means of preventing the formation of pseudoaneurysm.

Myocardial infarction (MI) remains a common fatal disease all over the world. The adult cardiac myocytes regenerative capability is very limited after infarct injury. Heart transplantation would be the best therapeutic option currently but is restricted due to the lack of donor organs and the serious side effects of immune suppression. The emerging of tissue engineering has evolved to provide solutions to tissue repair and replacement. Engineering myocardial tissue is considered to be a new therapeutic approach to repair infarcted myocardium and ameliorate cardiac function after MI. Engineering myocardial tissue is the combination of biodegradable scaffolds with viable cells and has made much progress in the experimental phase. However, the largest challenge of this field is the revascularization of the engineering constructs to provide oxygen and nutrients for cells. This review will give an overview on the current evolution of engineering myocardial tissue and address a new method to improve the vascularization of myocardium tissue in vivo.
