Sealing the breach: successful surgical management of post-myocardial infarction left ventricular pseudoaneurysm.

Left ventricular (LV) pseudoaneurysm, a rare occurrence, develops when a ruptured ventricle is encapsulated by the pericardium or scar tissue. Unlike free intrapericardial rupture, which often results in cardiac tamponade and fatal outcome, there are instances where the cardiac rupture remains contained, forming a pseudoaneurysm and averting immediate tamponade. We describe a 43-year-old male who underwent successful surgical repair of LV rupture following inferior wall myocardial infarction that resulted in the formation of a large pseudoaneurysm.

Background: Postoperative cerebral infarction, a serious complication of surgery, is occasionally experienced with pulmonary vein stump thrombosis (PVST), which is frequently observed after left upper lobectomy (LUL). Herein, we prospectively investigated whether PVST could be safely prevented by intrapericardial ligation of the superior pulmonary vein (SPV) to shorten the SPV stump during LUL.
Methods: In a consecutive 21 patients who underwent LUL, we ligated the proximal intrapericardial SPV with 1-0 silk suture and divided the distal hilar SPV by an automatic stapling device.
A case series of VATS intrapericardial pneumonectomy: a bi-centric experience.

Background: Intrapericardial pneumonectomy is a complex procedure indicated for large lung tumors where safe dissection of major vascular structures outside the pericardium is unfeasible or when the pericardium itself is invaded. Traditionally managed via open thoracotomy, recent advancements in VATS techniques now allow for intrapericardial pneumonectomy even in cases with extensive tumors or locally advanced disease. In this article, we detail the clinical outcomes and surgical considerations of six patients with non-small cell lung cancer who underwent VATS intrapericardial pneumonectomy.

Ischemic preconditioning (IPC) therapy application to attenuate myocardial ischemia-reperfusion (MI/R) injury in clinical practice remains challenging. The secretome, derived from hypoxia-preconditioned cardiomyocytes (SHPC), potentially mimics the IPC microenvironment and facilitates IPC clinical translation. This study aims to determine whether SHPC can be a feasible alternative to IPC for attenuating MI/R injury, and to identify the functional factor of SHPC.

Background: Initially conceptualized as a bridge to heart transplantation, the left ventricular assist device (LVAD) has become an important option for improving survival in patients with severe heart failure and poor prognosis.
Case Summary: We report the case of a patient suffering from severe chronic heart failure, complicated by ST-elevation myocardial infarction due to left main coronary artery stenosis (NYHA IV, INTERMACS profile 1). Despite support with veno-arterial extracorporeal membrane oxygenation, inotropes, and catecholamine therapy, the patient's cardiac function did not recover sufficiently.
