Certain recent studies have demonstrated improved surgical outcome in patients with aortic dissection. We analyzed the survival rates of acute dissections and late prognosis those dissection during a 30-year period.Between 1963 1992, 360 (256 men 104 women; mean +/- 1 SD age, 57 14 years) underwent surgery for dissection: 174 had an type A (AcA), 46 B (AcB), 106 chronic (ChA), 34 (ChB) The overall operative mortality rate was 24 8% (26 3% AcA, 39 AcB, 17 4% ChA, 15 6% ChB, [+/- 70%...
The Incidence of peripheral vascular complications in 272 patients with aortic dissection during a 25-year span was determined, as outcome after uniform, aggressive surgical approach directed at repair the thoracic aorta. One hundred twenty-eight (47%) presented acute type A dissection, 70 (26%) chronic A, 40 (15%) B, and 34 (12%) B dissections. Eighty-five (31%) sustained one or more complications: Seven (3%) had stroke, nine paraplegia, 66 (24%) loss pulse, 22 (8%) Impaired renal...
Background— The edge-to-edge technique is an accepted method for the surgical repair of a regurgitant mitral valve. This study reports initial use endovascular technology that enables double-orifice valve without cardiopulmonary bypass in animal model. Methods and Results— Adult pigs (n=14) were anesthetized, left thoracotomy was performed epicardial echo imaging. Using femoral vein access, steerable guide catheter placed transseptally into atrium. An implantable clip designed to grasp...
Surgical edge-to-edge repair has been used in the treatment of mitral regurgitation. We evaluated ability a catheter-delivered clip (Evalve, Inc) to achieve valve approximation without cardiopulmonary bypass and healing response this technique.Twenty-one pigs underwent general anesthesia left thoracotomy. A 10F flexible delivery catheter with was placed into atrium. With echocardiographic fluoroscopic guidance, grasped approximated mid portion anterior posterior leaflets. After double...
For the past 25 years, porcine valves have been most widely implanted bioprosthesis, thereby becoming standard for comparison with newer bioprosthetic valves.We retrospectively analyzed 2,879 patients who underwent aortic (AVR; n = 1,594) or mitral (MVR; 1,285) valve replacement between 1971 and 1990. Follow-up was 97% complete extended to 20 years (total, 17,976 patient-years). Patient age ranged from 16 94 years; mean in AVR 60 +/- 15 (+/- deviation) that MVR 58 13 years.The operative...
A 68-year-old woman with severe chronic obstructive pulmonary disease, aortic valvular insufficiency, and diffuse thoracic aneurysm underwent valve replacement separate Dacron graft of the ascending arch aneurysms using elephant trunk technique. She was discharged on tenth postoperative day. Five months later, she endovascular stent-graft repair descending aneurysm. recovered uneventfully, third Follow-up computed tomography at 6 demonstrated exclusion all flow into The technique followed by...
Patients with aneurysmal disease involving both the descending thoracic and abdominal aorta have historically required simultaneous or sequential conventional operations, but morbidity rate is high either approach in these patients, who often exhibit coexisting cardiopulmonary disease. Transluminally placed endovascular grafts recently been developed for repair of aortic aneurysms, we implemented techniques to eliminate need a thoracotomy patients multilevel disease.Since January 1994, 18...
With an estimated incidence of 6 cases per 100,000 population year, patients with thoracic aortic aneurysms are not infrequently encountered by cardiovascular surgeons, especially as the ages.1, 29, 30 Traditionally, only effective treatment descending has been open surgical graft replacement through a left thoracotomy. Despite efforts to minimize perioperative complications, including earlier operation before rupture, better cardiopulmonary bypass (CPB) circulatory support, and preservation...
A less invasive approach to cardiac surgery has been propelled by recent advances in video-assisted surgery. Previous obstacles minimally operations with cardioplegic arrest included limitations operative exposure, inadequate perfusion technology, and inability provide myocardial protection.Port-access technology allows endovascular aortic occlusion, cardioplegia delivery, left ventricular decompression. The endoaortic clamp is a triple-lumen catheter an inflatable balloon at its distal end....
