An 83-year-old man had acute type B aortic dissection combined with a large athelosclerotic abdominal aortic aneurysm (AAA) over 8cm in diameter. The dissection advanced into the wall of the AAA. The patient was treated with strict medical therapy for two months and successfully underwent an early elective abdominal aortic repair concomitant with off-pump aortocoronary bypass grafting. This strategy of meticulous medical management may improve clinical outcome for the acute phase in such rare cases.

A 64-year-old man who had chronic aortic dissecting aneurysm with true lumen obstruction of the abdominal aorta was referred to our hospital for surgery. He underwent total aortic arch replacement with the elephant trunk technique using an aortofemoral artery bypass as a first-stage operation. Reconstruction of the thoracic aortic descending aneurysm using the previous elephant trunk graft in a second-stage operation was feasible. His perioperative course was uneventful and he had no neurologic complications.

We report an 81-year-old woman with giant left atrial myxoma who had been admitted with congestive heart failure. Diagnosis was established by echocardiography and a moderate degree of tricuspid valve regurgitation was also found. The tumor was extensively attached to the atrial septum, and was excised completely including endocardium. She had concomitant tricuspid annuloplasty. Atrial fibrillation occurred on postoperative day 10, but conversion to a sinus rhythm was seen on postoperative day 19. She was discharged in good condition on postoperative day 36. Even in a patient over 80 years old with congestive heart failure, aggressive surgical treatment of left atrial myxoma should be performed.

We report a 66-year-old woman with circulatory collapse due to acute pulmonary thromboembolism, in whom a left nephrectomy for a renal tumor was scheduled. Following preoperative renal angiography. The patient suffered sudden shock resulting from pulmonary thromboembolism (PTE) following release of compression of the puncture site. The patient was transported to the ICU, and percutaneous cardiopulmonary support (PCPS) was instituted immediately for resuscitation. Hemodynamics were stabilized by PCPS and percutaneous thrombectomy was attempted. However, perforation by a catheter inverted to the extracardiac space occurred, which neccesitated emergency surgical hemostasis. PCPS was converted to cardiopulmonary bypass (CPB). The injured right ventricle and right atrial walls were repaired, and pulmonary thrombectomy was performed via the pulmonary trunk. CPB was easily terminated and her postoperative course was uneventful with anticoagulant therapy. Left nephrectomy was performed two months later. PTE recurred due to the interruption of anticoagulation for surgical treatment of a renal tumor. Percutaneous pulmonary thrombectomy and thrombolysis therapy were effective and a Greenfield filter was inserted into the inferior vena cava to prevent recurrence.

We present an unusual case of a delayed right ventricular perforation by a single standard-caliber implantable cardioverter-defibrillator lead, which manifested 14 days after implantation. Multidetector computed tomography could clearly display the lead perforation, and allow for identification of the associated sequelae such as pericardial effusion and planning the lead extraction strategy.

Autophagy is a housekeeping process that maintains cellular homeostasis through recycling of nutrients and degradation of damaged or aged cytoplasmic constituents. Over the past several years, accumulating evidence has suggested that autophagy can function as an intracellular innate defense pathway in response to infection with a variety of bacteria and viruses. Autophagy plays a role as a specialized immunologic effector and regulates innate immunity to exert antimicrobial defense mechanisms. Numerous bacterial pathogens have developed the ability to invade host cells or to subvert host autophagy to establish a persistent infection. In this review, we have summarized the recent advances in our understanding of the interaction between antibacterial autophagy (xenophagy) and different bacterial pathogens.

We present the case of a 72-year-old man with constrictive pericarditis due to tuberculous pericarditis, who was treated with the waffle procedure via left anterolateral thoracotomy. The preoperative catheterization study showed the dip-and-plateau pattern, and the echocardiographic study shown the thickened pericardium and dilatation impairment. The surgery was able to be performed without cardiopulmonary bypass. The thickened pericardium was abraded with a Harmonic Scalpel. The waffle procedure was effective in this patient. The postoperative course was good, with improvement of NYHA status and cardiac pressure study results. We suggest that this procedure is useful for the patients with constrictive pericarditis.
