Off-pump awake coronary revascularization using bilateral internal thoracic arteries.

BACKGROUND: A new technique has been developed that permits complete arterial revascularization of the lateral and/or inferior wall of the heart using in situ bilateral internal thoracic artery grafts in awake patients. This technique, without cardiopulmonary bypass and mechanical ventilation, creates the least invasive revascularization method for the lateral and/or posterior wall of the heart yet described. METHODS: In 7 patients double or triple vessel coronary artery bypass grafting was performed without general anesthesia. A high thoracic epidural anesthesia was started one hour before surgery. Bilateral internal thoracic arteries were harvested and all anastomoses were performed with the off-pump technique by standard median sternotomy. Circumflex, or the right coronary artery, were anastomosed with bilateral internal thoracic arteries using a heart positioner. Six patients received double bypass grafting and one patient received triple bypass grafts (bilateral internal thoracic arteries and one radial artery). RESULTS: All patients remained awake throughout the whole procedure. There was no perioperative myocardial infarction or mortality. Pneumothorax was observed in three patients, but it was repaired in two. Only one patient completed the procedure with unilateral pneumothorax. There were no hemodynamic and pulmonary problems during lateral or posterior wall revascularization. Two patients required unexpected coronary endarterectomy during circumflex and right coronary artery anastomoses. CONCLUSIONS: Complete arterial revascularization by median sternotomy using in situ bilateral internal thoracic artery grafts without general anesthesia is a feasible and safe procedure for multivessel disease. This approach gives a chance for awake revascularization of the right and/or circumflex coronary artery.

Rupture of the abdominal aorta in a 13-year-old girl secondary to Behçet disease: a case report.

Behçet disease is a multisystemic vasculitis of unknown origin. The vascular complications as a result of the disease are rare in the pediatric age group. We report a 13-year-old patient with vasculo-Behçet disease with a ruptured abdominal aortic aneurysm without a formerly known history of Behçet disease. Urgent aortoiliac bypass with a polytetrafluoroethylene graft was performed with success, and the patient has also received corticosteroid and immunosuppressive drug therapy.

Partial cardiac autotransplantation for reduction of the left atrium.

Various surgical procedures have been employed to treat a greatly enlarged left atrium. We review the use of partial cardiac autotransplantation to reduce left atrial volume in 7 patients with rheumatic mitral valve disease and left atrial and ventricular volume in 2 patients with idiopathic dilated cardiomyopathy. There were 5 males and 4 females aged 25 to 62 years. The patients with rheumatic etiology had atrial fibrillation, while those with dilated cardiomyopathy had sinus rhythm. The mitral valve was replaced in 6 patients and reconstructed in 3. Mean aortic cross clamp time in the operations involving isolated left atrial resection was 119 +/- 44 min. Mean left atrial volume fell from 331 mL to 92 mL, while mean left atrial diameter decreased from 8.6 cm to 4.7 cm. Sinus rhythm was restored in 5 of the 7 patients who had preoperative atrial fibrillation. There was no operative mortality. The patients with dilated cardiomyopathy died in the postoperative period, one on the 14th day from low cardiac output and the other on the 113th day from multiorgan failure. Partial cardiac autotransplantation can be effective in reducing heart chamber size in selected patients, especially those with giant left atrium.

Evolution of repaired and non-repaired tricuspid regurgitation in rheumatic mitral valve surgery without severe pulmonary hypertension.

The aim of this study was to evaluate the usefulness of repairing significant tricuspid regurgitation (> or = grade 2) without severe pulmonary hypertension (< or = 50 mm Hg). Between 1993 and June 2001, 88 consecutive patients were operated on for rheumatic mitral valve disease associated with significant tricuspid regurgitation and without severe pulmonary hypertension. The severity of the tricuspid valve disease was assessed by echocardiography. Sixty-three patients had severe (> or = grade 3) tricuspid regurgitation (Group I), and 25 patients had moderate (grade 2) tricuspid regurgitation (Group II). There was no hospital mortality. six patients died during follow-up. The overall actuarial survival rate for 8 years was 92.1% +/- 3.1%. Cox proportional hazard regression analysis showed that age ( p = 0.006) and pulmonary complication ( p = 0.01) were associated with increased late mortality. Freedom from death was similar in both groups at 8 years (93.1% +/- 3.3% versus 88% +/- 8%, p = 0.7). Severe postoperative tricuspid regurgitation (> or = grade 3), caused by the failure of tricuspid repair or leaving the valve untouched, impaired long-term survival after surgery, and actuarial survival was 96.1% +/- 2.7% and 83% +/- 7.8% at 7 years ( p = 0.048), respectively. Severe tricuspid regurgitation, functional or organic, should be corrected at the time of mitral valve surgery, whereas untouched functional moderate tricuspid regurgitation improves after mitral valve surgery.

Combined coronary artery bypass grafting and lung surgery.

Combined coronary bypass and lung surgery was performed in 3 patients. Through a median sternotomy or a left thoracotomy, bypass grafting was performed on beating heart or under cardiopulmonary bypass, followed by the lung operation. The lung lesion was diagnosed as carcinoma in 2 patients and hydatid cyst in 1 patient. With few exceptions, beating heart coronary bypass through a median sternotomy can be performed in a combined operation.

Surgical outcome of subtypes of aortic arch dissection.

This study was conducted to investigate if the site of primary intimal tear involving the aortic arch and the surgical approach affect the early and late results of total aortic arch replacement. Between 1993 and November 2001, 42 patients underwent graft replacement of the total aortic arch for aortic dissection. Their mean age was 51.9 +/- 9.8 years, and 38 of them were male. All operations were performed under hypothermic circulatory arrest with retrograde cerebral perfusion. Hospital mortality was 28.6% (12 patients). There were 2 late deaths. Multivariate analysis showed that chronic obstructive pulmonary disease and ascending aortic replacement with or without valve replacement were significant independent determinants of early death. Patients with the intimal tear originating in the ascending aorta showed a tendency towards lower 7-year survival rates than those with a tear at other aortic sites or with multiple tears, while the presence of chronic obstructive pulmonary disease adversely affected early and late outcomes. We conclude that the primary site of an intimal tear that involves the aortic arch affects early and late survival, but concomitant non-cardiac diseases play an even more important role in the early outcome as they increase the complexity of the operation.

[Surgical treatment of iatrogenic cardiac traumas induced by heart catheterization].

BACKGROUND: A retrospective evaluation was made on iatrogenic cardiac traumas requiring surgical treatment, that were induced by cardiac catheterizations and interventions performed within a 17-year period. METHODS: A total of 64,911 patients underwent cardiac catheterizations and interventions from 1985 to 2002. Complications of iatrogenic cardiac traumas induced by these interventions were examined together with the surgical treatment performed within 24 hours after catheterization. RESULTS: Iatrogenic cardiac trauma requiring prompt surgical intervention was documented in 20 patients (6 females, 14 males; mean age 51 years; range 31 to 69 years). These were due to coronary angiography/balloon angioplasty-stenting in 14 (70%), percutaneous mitral balloon valvuloplasty in four (20%), and to heart catheterization in two patients (10%). Acute cardiac tamponade was detected in 10 patients (50%) resulting from perforations to the cardiac chambers in six, coronary arteries in two, and major vessels in two patients. Surgical interventions included coronary artery by-pass in 14, mitral valve surgery in four, and repair of major vessels in two patients. Perioperative mortality occurred in two patients. Six patients developed complications contributing to morbidity, including perioperative myocardial infarction (3 patients), infection (2 patients), and prolonged intubation (1 patient). CONCLUSION: In case of major cardiac complications induced during cardiac catheterizations, early diagnosis and prompt surgical intervention are of vital importance regardless of considerably high risks.

[Traumatic vascular complications due to intraaortic balloon pump support].

BACKGROUND: The use of an intraaortic balloon pump (IABP) catheter was retrospectively evaluated in terms of risk factors, insertion techniques, and complications in patients with low cardiac output. METHODS: A total of 1036 patients (804 males, 232 females; mean age 53.4 years; range 16 to 75 years) received IABP support from 1985 to March 2002. Of these, 789 patients (76.1%) underwent open heart surgery, 247 patients (23.8%) developed low cardiac output during medical treatment. Insertion of IABP was performed via the femoral artery either percutaneously by the Seldinger technique in 897 patients (86.6%), or by direct surgical exposure in 88 patients (8.5%). Open surgical IABP insertion was performed through an 8 mm Dacron graft placed with an end-to-side anastomosis to the common femoral artery (88 patients) or to the ascending aorta (23 patients). RESULTS: The overall mortality rate was 35.1% (364 patients). Vascular complications were associated with IABP in 104 patients (10%), of which 57 patients (5.5%) required surgical treatment. Major complications were aortic arch dissection in two patients and paraplegia in two patients. Vascular complications tended to increase with female gender, older age, diabetes, and peripheral vascular disease. The mean duration of IABP support in the presence of vascular complications was 7.8 days (range 5 hours to 77 days). CONCLUSION: Application of unsheathed IABP and proper evaluation of peripheral circulation seem to decrease the incidence of vascular complications.

Does radial artery harvesting cause any changes in the forehand circulation during the postoperative period? An angiographic study.

OBJECTIVE: The aim of this study was to evaluate angiographic changes in the ulnar and interosseous arteries, and the collateral circulation of forehand after harvesting radial artery. METHODS: Forty patients were studied between June 1998 and June 2001. Study group consisted of 30 patients who received radial artery as a conduit for coronary artery bypass operation, and control group consisted of 10 patients who did not undergo any cardiac or vascular operation before. Preoperative risk factors were similar between the two groups. All patients underwent angiographic evaluation to detect coronary artery and left forehand arterial circulation. RESULTS: Angiographic evaluation was performed 25.5 +/- 2.0 months after the initial operation in the study group. Mean diameter of ulnar artery was 2.9 +/- 0.59 mm (range 2.1 - 4.8) in the study group and 3.2 +/- 0.8 mm (range 1.5 t- 4.7) in the control group (p >0.05). Mean diameter of interosseous artery was significantly higher in the study group than in control one: 2.06 +/- 0.57 mm (range 1.2 t- 4.2) versus 1.46 +/- 0.79 mm (range 0.8 t- 3.6); (p = 0.003). CONCLUSION: Although angiography was performed in a limited number of patients, interosseous artery rather than ulnar artery enlarged to compensate blood supply of forehand 25 months after harvesting the radial artery for coronary artery bypass grafting.

Complete off-pump coronary revascularization in patients with dialysis-dependent renal disease.

Patients who have dialysis-dependent renal disease frequently present with coronary artery disease but are considered at high risk for coronary artery bypass grafting. From 1 September 2000 through 31 August 2003, we performed complete off-pump coronary revascularization in 6 patients who had end-stage dialysis-dependent renal failure, and we prospectively studied the perioperative and early postoperative results. The effect of off-pump coronary artery bypass grafting on mortality, morbidity, postoperative complications, and transfusion requirements in this group of patients was investigated. No perioperative deaths or ischemic cardiac events were observed after off-pump coronary artery bypass grafting. In all patients, anginal symptoms were relieved during the postoperative period. The mean duration of follow-up was 172 +/- 12.4 months. Patients with dialysis-dependent chronic renal failure who present with coronary artery disease should be thoroughly evaluated preoperatively for risk factors and coexistent severe diseases. We believe that in patients with end-stage dialysis-dependent chronic renal failure, off-pump coronary revascularization is a good alternative.

Endovascular treatment of intracerebral mycotic aneurysm before surgical treatment of infective endocarditis.

Mycotic aneurysms are rarely seen in patients who have infective endocarditis, and the management of these patients remains controversial. We present the case of a patient who had infective endocarditis complicated by a mycotic aneurysm of the left middle cerebral artery. There was substantial mitral regurgitation, and Streptococcus viridans was isolated from the blood samples. Dysarthria appeared during the 4th week of the antibiotic therapy, but resolved completely 8 hours after onset. The left middle cerebral artery was embolized with platinum detachable coils. On the 7th day after the radiologic intervention, the native mitral valve was replaced with a 33-mm St. Jude Medical bi-leaflet mechanical mitral prosthesis. Most mycotic aneurysms show notable regression of symptoms with effective antibiotic treatment, and a very few may diminish in size. However it is impossible to predict the response of these aneurysms to therapy. To prevent the perioperative rupture of mycotic aneurysms and intracranial hemorrhage, priority should be given to endovascular interventions to treat cerebrovascular aneurysms in patients such as ours.

Is posterior leaflet extension and associated commissurotomy effective in rheumatic mitral valve disease? Long-term outcome.

In this prospective study, the long-term effect of posterior leaflet extension with glutaraldehyde-preserved autologous pericardium and associated mitral valve commissurotomy was investigated in patients with mixed mitral valve disease of rheumatic origin. Mitral commissurotomy and posterior leaflet extension using a pericardial patch were performed in 25 patients from 1 January 1994 through 31 December 1995 for mixed mitral valve disease. Preoperatively, no patient had chordal rupture or papillary muscle dysfunction. Four patients had left atrial thrombosis. The mean age was 35.7 +/- 15.4 years. Associated procedures were tricuspid annuloplasty in 4 patients, aortic annuloplasty in 3, aortic and tricuspid annuloplasty in 1, and aortic homograft replacement in 1. There were no early deaths. One patient died 2 years after surgery due to noncardiac causes. Mitral valve area increased from 1.53 +/- 0.63 cm2 to 2 +/- 0.33 cm2 (P = 0. 09), and left atrial diameter decreased from 5.8 +/- 1 cm to 4.86 +/- 1.27 cm (P = 0.07) after 6.1 +/- 0.7 years (range, 5.5 to 71 years). Mitral insufficiency was reduced significantly, from grade 2.65 +/- 0.9 to grade 1.2 +/- 0.9 (P = 0.007). Functional capacity improved in all patients (New York Heart Association functional class, 3 +/- 0.58 preoperatively vs 1.44 +/- 0.82 postoperatively; P = 0.001). Three patients required reoperation and valve replacement. This type of reconstruction may be a good alternative for patients who are not able to use anticoagulant therapy. Long-term results of this technique are acceptable; however, the risk of reoperation is an important disadvantage in these young patients.

Epicardial mesothelial cyst located over the left anterior descending coronary artery.

We report the 5th case of pericardial cyst found to originate from epicardium. A 30-year-old woman with a history of rheumatic fever underwent open-heart surgery for severe aortic and mitral insufficiency. A cyst located over the left anterior descending coronary artery was detected during surgery. Excision of the cyst was performed with the patient on cardiopulmonary bypass, to avoid injury to the artery. Histologic examination showed the cyst to be lined by a single layer of benign mesothelial cells, which was consistent with a diagnosis of epicardial mesothelial cyst.

Surgical treatment of aortic abscess and fistula.

The formation of annular abscess and fistulous communication, the most devastating complication of destructive aortic valve endocarditis, requires extensive surgical débridement. Five men experienced destructive native aortic valve endocarditis in association with congestive heart failure (New York Heart Association functional class IV) and hemodynamic deterioration that developed from severe aortic regurgitation. To eradicate the aortic valve endocarditis, we performed (from July 1998 through November 2002) aortic annular skeletonization by dissecting all infectious and necrotic tissue within the abscess cavity and the fistula between the ventriculoarterial junction and the sinotubular junction. The completely resected annular area was covered with a glutaraldehyde-treated autologous pericardial patch that was sutured firmly to fibrous tissue, for a secure proximal anastomosis. Reconstruction of the aortic root was followed by implantation of a Freestyle stentless bioprosthesis, using the aortic root replacement technique. There were no deaths after surgery, nor is there record of a permanent complication due to a loss of conduction tissue. All 5 patients were in New York Heart Association functional class I or II during follow-up (range, 8-56 months). Echocardiography showed no signs of valve dysfunction, recurrent endocarditis, or fistulation. Annular skeletonization and reconstruction of the aortic annulus with glutaraldehyde-treated autologous pericardium permits radical removal of infected tissue and effective treatment of aortic annular abscess, with less risk of valve dehiscence from the fragile aortic annulus.

Rupture of abdominal aortic aneurysms in Behçet's disease.

Behget's disease is a systemic disease of unknown etiology with a chronic relapsing course,characterized by oral aphtous, genital ulcers, ocular lesions, and occasionally vasculitis. Major asymptomatic vascular complications should always be considered in patients with Behget'sdisease. We present the surgical treatment of two male Behget's patients of 41 and 30 years of age with ruptured infrarenal abdominal aortic aneurysms. The urgent repairs of ruptured abdominal aortic aneurysms were performed successfully in both patients. Because Behget's disease is usually seen at young ages, vascular assessment should also be done routinely for early diagnosis and therapy, which can be life-saving.
