Since its introduction in Japan in 1980, the extracorporeal left ventricular assist device has been used as a bridge to the recovery of cardiac function or to heart transplantation by many institutions. In this case report, we describe a 23-year-old female with peripartum cardiomyopathy. She had a persistently low cardiac index despite intensive care with intravenous inotropes, intra-aortic balloon pumping and extracorporeal membrane oxygenation; thus, we implanted an extracorporeal left ventricular assist device. Thereafter, her cardiac function gradually improved; the device was removed 2 months after the implantation. She currently has good heart function.

While isolated iliac artery aneurysm is rare, its rupture can lead to complete circulatory collapse and possibly death. Herein, we report a case of rupture of a large isolated aneurysm of the right common iliac artery that led to circulatory collapse and rapid endovascular repair saved the patient's life.

Minimally invasive cardiac surgery has recently become widespread because it has few disadvantages. However, lung hernia has been reported as a rare complication of minimally invasive cardiac surgery (MICS), and normally requiring additional surgical procedures. We describe herein a case of manual repositioning of lung hernia after MICS.

A Kommerell’s diverticulum is a rare congenital aortic arch anomaly associated with a high rate of aortic rupture or dissection. Therefore, surgical or endovascular repair should be considered early. A 64-year-old man was incidentally found to have an aortic arch anomaly, Kommerell’s diverticulum, with a right aberrant subclavian artery and distal arch aneurysm. Hybrid total arch replacement with bilateral extra-anatomical axillary artery bypass and frozen elephant trunk technique was performed. This particular surgical approach would be a treatment option for any type of Kommerell’s diverticulum.
