ABSTRACT

A 79-year-old woman presented to our hospital with high energy trauma. Enhanced CT revealed injury to the aortic arch. The left carotid artery was pulled out due to extension force and a drawing out lesion formed. Cardiopulmonary bypass was established with cannulation of the right femoral artery and the right atrium, and systemic cooling was started. We opened the aortic arch with deep hypothermic circulatory arrest, and detected a 10 mm drawing out lesion at the bottom of the left carotid artery. Aortic arch was transected at the distal of the left carotid artery to exclude the drawing out lesion, and partial arch replacement was performed. The patient's postoperative course was uneventful, and she was discharged from our hospital without any complication.

ABSTRACT

Blunt traumatic rupture of the heart carries a high mortality rate. Anatomical injuries have included the atrium, appendage and ventricle but injury to the left appendage has been reported very rarely. We present the case of a 71-year-old female who was a driver in a motor collision with major front-end damage where air bags were deployed. After being intubated and receiving pericardiocentesis for cardiac tamponade at an advanced critical care and emergency medical center, the patient was taken to our hospital and emergently to the operating room for exploration. There was brisk bleeding coming from a 2 cm laceration on the left atrial appendage. The injury was repaired using 4-0 polypropylene felt pledget-supported horizontal mattress sutures on the beating heart with the assistance of cardiopulmonary bypass. The present report describes this patient and our findings from a literature review.

ABSTRACT

An 87-year-old man underwent a transcatheter aortic valve implantation (TAVI) for severe aortic stenosis. Approximately 8 months later, he was readmitted to our institution because of a cerebral infarction. Viridans Streptococcus was identified from the blood culture, and transesophageal echocardiography revealed a mobile mass on the leaflet. Prosthetic valve endocarditis (PVE) was diagnosed and we initially administered intravenous antibiotic therapy for 4 weeks, after which the patient underwent surgical aortic valve replacement. Herein, we report on the surgical AVR in the patient using a pericardial valve after successful removal of the infected prosthetic valve, and discuss some issues related to this rare complication after TAVI.

ABSTRACT

The patient was a 34-year-old woman who had been routinely monitored after receiving a childhood diagnosis of partial anomalous pulmonary venous connection, but unilaterally discontinued follow-up examinations after the age of 18. At 33 years of age, she was admitted to our hospital after a physical examination revealed an abnormal shadow on a chest X-ray. Transthoracic echocardiography detected an atrial septal defect (ASD), and contrast-enhanced computed tomography showed that the right lower pulmonary vein drained to the inferior vena cava. The patient was diagnosed with scimitar syndrome with ASD. Cardiac catheterization showed a pulmonary/systemic flow ratio (Qp/Qs) of 2.48 and a left-to-right shunt rate of 59.7%. Surgical treatment was deemed to be indicated. The right lower pulmonary vein was anastomosed to the anterolateral wall of the right atrium, and an intra-atrial baffle repair was performed from the orifice within the right atrium to the left atrium through the existing ASD using untreated fresh autologous pericardium. Two years after the operation, good blood flow was maintained within the baffle with no stenosis at the anastomotic site. This report describes a rare case of scimitar syndrome with ASD in an adult woman, and provides a review of the existing literature.

ABSTRACT

<p>We report a case of type A acute aortic dissection in a patient with situs inversus totalis. A 51-year-old man was hospitalized with sudden-onset back pain. Contrast-enhanced computed tomography revealed Stanford type A acute aortic dissection and situs inversus totalis. Total arch replacement using selective cerebral perfusion and mild hypothermic circulatory arrest was successfully performed. He was discharged home 23 days after the operation.</p>

ABSTRACT

<p>A 45-year-old man was hospitalized with sudden-onset chest pain. He was in cardiogenic shock with a systolic pressure of 68 mmHg. His electrocardiogram (ECG) showed ST segment elevation in leads I, aVL, and V2-5. An emergency coronary angiogram (CAG) showed that the true lumens of bilateral coronary arteries were compressed, showing acute Stanford type A aortic dissection involving bilateral coronary artery. A bare metal stent was promptly implanted in the left main trunk (LMT) to restore coronary blood flow because of his hemodynamic instability. Soon afterwards, the ischemic changes on ECG disappeared and he was transferred to the operating room in a stable hemodynamic condition. We performed emergency graft replacement of the ascending aorta and coronary artery bypass grafting. The postoperative CAG showed patent bypass grafts. Implantation of LMT stent, as a bridge to surgery, should be the treatment of choice for acute type A dissection involving LMT.</p>
