Left atrial dissection (LatD) is an exceedingly rare but serious complication of cardiac surgery. Its clinical presentation is very different in individual cases. Surgical treatment for LatD is often selected when the patient is hemodynamically unstable; conservative treatments are commonly employed under stable conditions. We report a case of LatD after mitral valve replacement that was treated surgically with creation of an atrial fenestration.

Patients undergoing robotic-assisted coronary artery bypass grafting are increasing. Several complications have emerged with the increasing use of minimally invasive procedures. We reported a case of spontaneous tension pneumothorax that developed in the ventilated lung during robotic assisted left internal mammary artery harvesting causing severe hemodynamic instability. A sudden rise of airway pressure occurred, and the patient became hypotensive. Immediately, the surgeon was notified to look at the right pleura. Pneumothorax was identified, the right pleura was opened using robotic arms, and the right lung was decompressed. A small emphysematous bulla was identified and stabled. Proper identification of the procedure-associated complications is essential for timely management. Tension pneumothorax is a potentially fatal complication, especially in patients under positive pressure ventilation.

Management of patients with end-stage heart failure is still challenging. We report a case of idiopathic dilated cardiomyopathy who went through a challenging course. The case was presented as acute heart failure syndrome, which rapidly declined into cardiogenic shock and cardiac arrest that required an extracorporeal membrane oxygenator, then biventricular assist device implantation for circulatory support. The course was complicated with severe gastrointestinal bleeding and multiorgan failure until achieving full cardiac and organ recovery. The left ventricle ejection fraction improved from 10% to 50% at discharge.

Currently, there is a lack of expert consensus and clinical guidelines about the treatment strategy for aortic roots in patients with acute Stanford type A aortic dissection with aortic sinuses less than 45 mm in diameter and without combined connective tissue disorder. The physiological aortic sinus plays a key role in the protection of the aortic valve and cardiac function. Thus, we invented a "watching without dealing with" technique of aortic root repair to preserve the aortic sinus as much as possible. This technique could simplify the operation and improve the patient's prognosis, which is worth learning and promoting.

We report an unusual case of giant intracardiac medullary thyroid cancer metastasis. A 76-year-old woman with a 9-year history of medullary thyroid cancer presented an unexpected 7.5 cm mass in the right ventricle. Complete resection and tricuspid valve replacement led to 40 months survival.

An LSCA aneurysm is a rare disease. When and how to operate are debated. While open surgery was initially considered the sole option, emerging endovascular techniques have been described. The present report describes a novel hybrid technique to treat an LSCA aneurysm combined to a proximal descending aneurysm in a young 25-year-old patient.

Aorto-tracheal fistulas are rare and highly lethal, with few reports of successful surgical intervention. We present a 48-year-old man with an aorto-tracheal fistula induced by radiation therapy for tracheal squamous cell carcinoma. He presented with hemoptysis and chest pain and workup revealed the aorta-tracheal fistula between the posterior aortic arch and anterior distal trachea. He was emergently taken to surgery. To our knowledge, this is the first report of an aorto-tracheal fistula successfully treated with a transverse aortic arch replacement and complex tracheal repair using autologous pericardium with an omental buttress.

Due to the limitations of surgical incisions and approaches brought on by the presence of gastric tube (GT), open heart surgery following ante-thoracic route GT reconstruction remains challenging. A-73-year-old man, who had a history of esophageal resection and ante-thoracic route GT reconstruction required aortic valve replacement (AVR) concomitant with ascending aortic repair (AAR) for aortic stenosis and dilated ascending aorta. We performed open heart surgery via a right-parasternal approach to avoid injury to the GT and nutrient arteries. This approach provided a good operative field, similar to median sternotomy. To our knowledge, this is the first case of AVR concomitant with AAR after ante-thoracic route GT reconstruction via a right-parasternal approach. We consider that the right-parasternal approach is reasonable for patients with ante-thoracic route GT reconstruction.
