Dislocation of a stent-graft into the aortic arch during endovascular repair of a descending thoracic aortic aneurysm.
A 59-year-old man showed a saccular aneurysm due to a penetrating atherosclerotic ulcer, as well as a small type B aortic dissection located in the proximal descending aorta. The lesion was treated by the implantation of a stent-graft. On release, the stent-graft dislocated into the aortic arch. Intraoperative angiogram showed free perfusion of the brachiocephalic trunk and left common carotid artery; however, an overstenting of the carotid artery was apparent. Computed tomographic scan exhibited a complete covering of the supra-aortic vessels, and conventional, open aortic arch surgery was inevitable. A partial resection of the proximal part of the stent-graft was performed.

Implantation of a prosthesis mounted inside a self-expandable stent in the pulmonary valvar area without use of cardiopulmonary bypass.
Patients with right ventricular outflow tract reconstruction often require redo operations with time. Unique surgical problems exist in this group of patients. We report an innovative method of implantation of a pulmonary valve without the use of cardiopulmonary bypass.

Absent long-term benefit of patch versus linear reconstruction in left ventricular aneurysm surgery.
BACKGROUND: Endoventricular patch reconstruction of the left ventricle is considered the gold standard in surgery for left ventricular aneurysms, because of improved preservation of ventricular geometry. However, the superiority over conventional linear closure has not been demonstrated, as assessed by the long-term outcome. METHODS: Two hundred patients (66%) underwent linear closure (group L) and 105 patients (34%) had endoventricular patch reconstruction (group D) using the Dor technique. Linear closure has been performed since 1974 and from 1985 on the Dor technique has been applied as an alternative procedure. Both patient groups differed regarding age, sex distribution, site of infarction, and indication for surgery. Prior to the operation, 71% of the patients were in New York Heart Association (NYHA) class III or IV and mean ejection fraction was 34% +/- 12%. Follow-up extends up to 25 years, with a cumulative total of 2,605 patient years. RESULTS: Early mortality was 6.5% in group L vs 5.7% in group D (not significant [NS]). Actuarial survival after 10 years was 56 +/- 3.2%, with no difference between groups. Freedom from reoperation after 10 years was 95.6% in group L vs 95.2% in group D (NS). Preoperative risk factors for late mortality were age, left ventricular enddiastolic volume index and concomitant mitral valve surgery. The type of procedure and the date of operation had no influence on mortality. To date, 63% of the survivors are in NYHA class I and II. CONCLUSIONS: In regard to long-term survival, rate of reoperation, and postoperative NYHA functional class, no benefit could be demonstrated when linear closure was compared with ventricular patch reconstruction for LV aneurysm repair. Hence, the technique of ventricular reconstruction may not be as important as previously thought, and at least for small aneurysms the simple and time sparing technique of linear closure may still be considered.

Cardiac malignant tumor as a rare cause of acute myocardial infarction.
Acute myocardial infarction is predominantly caused by coronary artery atherosclerotic plaque rupture and subsequent occlusive thrombus formation. The recognition of less common causes of acute myocardial infarction is important because they may require a different treatment strategy. We report a patient with acute myocardial infarction without any angiographic evidence of coronary atherosclerosis and a left atrial mass detected on echocardiography. Therefore, coronary embolism from intracardiac thrombus or tumor was suspected. No additional manifestations of a potential tumor were found on thoracic, abdominal and cranial computed tomography. During subsequent cardiac surgery, a large tumor could be in toto resected and was diagnosed as a highly malignant leiomyosarcoma on histopathological evaluation.

[Rare case of enterovirus myocarditis with consecutive acute heart failure and subsequent "rescue therapy" with biventricular assist device].
PATIENT HISTORY AND FINDINGS: A 37-year-old woman was admitted in cardiogenic shock and multiorgan failure. On echocardiography, left ventricular function was reduced, at that time, to 35%. The patient had been suffering from a cold for 1 week prior to admission. Within 24 h, left ventricular function dramatically decreased to 7%. Examinations included left-and right-heart catheter evaluation with removal of right ventricular biopsies. Histology and molecular pathology revealed the diagnosis of an enteroviral myocarditis. THERAPY: Imminently, a biventricular assist device (BVAD -Berlin Heart) was implanted. POSTOPERATIVE COURSE: Postoperatively, only low-dose inotropic support was required. Under the requested anticoagulation, recurrent bleeding necessitated three rethoracotomies. Both renal and liver function normalized over time. On postoperative day 25, the BVAD was explanted without the need for cardiopulmonary bypass. Global ventricular function had normalized. The implantation of BVAD proved to be an efficient rescue therapy.

Modified bypass procedure and apicoaortic conduit. Management of coronary artery disease, aortic valve stenosis and porcelain aorta.
BACKGROUND: In case of severely calcified ascending aorta, modified operative strategies are required in order to avoid manipulations of the aorta and minimize subsequent cerebral vascular accidents. CASE REPORT: A 73-year-old woman, with a coronary two-vessel disease and aortic stenosis was scheduled for coronary artery bypass grafting and aortic valve replacement. Due to severed calcification of the ascending aorta including the transverse arch, neither cannulation, clamping nor incision of the aorta or its replacement was feasible. Therefore bypass operation was performed using a modified approach. After 1 month, implantation of a valved conduit between the left ventricular apex and the descending aorta through a lateral thoracotomy followed. CONCLUSION: Only in few cases the surgical treatment of a coronary artery disease in combination with left ventricular outflow tract obstruction and heavily calcified ascending aorta has been described. Undoubtedly, creation of an apicoaortic connection is today only indicated in the adult population in a small collective with multiple previous operations or porcelain aorta.
