Aortic valve sparing operations were developed to preserve the native aortic valve during surgery for aortic root aneurysm as well as surgery for ascending aortic aneurysms with associated aortic insufficiency. There are basically two types of aortic valve sparing oprations: remodeling of the aortic root and reimplantation of the aortic valve. These operations have been performed for over two decades and the clinical outcomes have been excellent in experienced hands. Although remodeling of the aortic root is physiologically superior to reimplantation of the aortic valve, long-term follow-up suggests that the latter is associated with lower risk of developing aortic insufficiency. Failure of remodeling of the aortic root is often due to dilatation of the aortic annulus. Thus, this type of aortic valve sparing should be reserved for older patients with ascending aortic aneurysm and normal aortic annulus whereas reimplantation of the aortic valve is more appropriate for young patients with inherited disorders that cause aortic root aneurysms. This article summarizes the published experience with these two operations. They are no longer experimental procedures and should be part of the surgical armamentarium to treat patients with aortic root aneurysm and ascending aortic aneurysms with associated aortic insufficiency.

Prolapse of the aortic valve is the main cause of insufficiency of the aortic valve as a complication of ventricular septal defect. Aortic insufficiency gets worse by the progress of prolapse of aortic valve due to lack of support of the valve and the hemodynamic effect of blood flow through the ventricular septal defect. This produces typical clinical picture, that may be serious and threatening when it is untreated. Type and timing for the surgical treatment of the ventricular septal defect with aortic insufficiency is considered. Among 113 ventricular septal defect, 9 patients of ventricular septal defect with associated aortic insufficiency were experienced from June. 1983 to June 1988 at the Department of Thoracic and Cardiovascular Surgery, Chon-Buk University Hospital. Male was 6 patients and female was 3 patients. Ages were from 7 years to 24years. 5 patients were from 10 to 19 years age. 3 patients were below 10 years age. The ratio of pulmonary blood flow to systemic f low [Qp/Qs] was 1.53 and in pulmonary vascular resistance, normal or slight increase was 7 patients, moderate 1 patient, and severe 1 patient. Ventricular septal defect was subpulmonic in 5 patients and infracristal in 4 patients. Prolapse of right coronary cusp was 7 patients, right and non coronary cusp 1 patient and non coronary cusp 1 patient. Teflon patch closure of ventricular septal defect was undertaken in 3 patients and primary closure in 1 patient. Among the 4 patients of defect closure alone, one patient performed valve replacement 7 months later due to progressive regurgitation and cardiac failure and the result was good. The other 3 patients were good result. Closure of ventricular septal defect and aortic valvuloplasty performed in 4 patients. 2 patients of these required valve replacement for the sudden intractable cardiac failure and died due to low cardiac output. The cause of intractable cardiac failure was tearing of repaired valve at the fixed site. The other 2 patients were good result. Closure of ventricular septal defect and valve replacement performed in 1 patient with good result.

The development of aortic insufficiency radically alters the physical findings which are generally associated with ventricular septal defect that was not hemodynamically significant, and the combination of the two lesions produces a typical clinical picture, that may be serious and life-threatening when it is left untreated. Therefore, the selection of patients, type and timing of surgical treatment is considered to be important. Among 114 cases of ventricular septal defect treated surgically utilizing cardiopulmonary bypass in the Department of Thoracic Surgery, Seoul National University Hospital, 7 cases were associated with aortic insufficiency. 1. Five cases were male, and 2 cases were female. Ages were from 4 years to 24 years, and mean age was 11.9 years. 2. In all cases, ventricular septal defect was closed with Teflon patch. In a case, a aortic valvuloplasty and in another, a aortic valve replacement with Hancock valve 23 mm., 5 months after the closure of ventricular septal defect were done. 3. Four cases were type I ventricular septal defect by Kirklin`s classification, 3 cases were type II ventricular septal defect, and diameters of ventricular septal defect were from 3.5 cm. to 0.7 cm. A PDA. was combined to a type I ventricular septal defect. 4. In 5 cases, herniation of the aortic cusp through the ventricular septal defect and in a case, annulus dilatation on the aortic valve was noted. 5. Two cases with type I ventricular septal defect and severe pulmonary hypertension expired. A re-opened case with type II ventricular septal defect expired. 6. Four cases were alive, and all of them show decrease of pulse pressure and aortic insufficiency.

Aortic valve insufficiency with ventricular septal defect is usually treatment by plication of prolased cusps. We have performed the aortic valvuloplasty by the Trusler`s method in 14 patients of ventricular septal defect associated with aortic insufficiency. The reoperations were performed in the 4 cases[29%] due to recurrent aortic insufficiency after aotic valvuloplasty. Two patients underwent aoritc valvular replacements for the tears of repaired aortic cusps after primary aortic valvuloplasty for aortic insufficiency. The other two patients had aortic valvuloplasties again. Death occured in one case of aortic valvular replacements. The cause of death was low cardiac output syndrome soon after aortic valvular replacement for recurrent aortic insufficiency .

Between January 1983 and December 1992, we had experienced 79 patients of ventricular septal defect [ VSD ] associated with aortic insufficiency [AI] which constitute 4.6 % of total numbers of VSD. The mean age of the patients was 10.2 years with a range of 1 to 35 years and the average degree of aortic insufficiency classified by Sellers was 2.1. The type of VSD was subpulmonic in 57 patients and perimembranous in 22. Most common pathologic finding causing AI was prolapse of right coronary cusp [ 54 cases ; 71.4% ] ,followed by prolapse of both right and non-coronary cusp[ 12 cases ; 7.9% ]. VSD closure alone was performed in 51 patients and their mean age was 7.7 years [ ranged 1 to 13 years ]. VSD closure and aortic valve reconstruction was performed in 22 patients, VSD closure and aortic valve replacement in 6 patients, and the mean age of the patients was 14.5 years [ ranged 2 to 28 years ], 20.4 years [ ranged 18 to 35 years ] respectively. There was no hospital mortality. All patients were followed up from 1 month to 9 year 4 months [average; 21.4 months ] and there was one late death. Our data suggests that, early closure of VSD without any manipulation on the valve may be sufficient procedure to improve or at least withhold progression of AI in children and furthermore patients with VSD associated AI should be corrected promptly after diagnosis.

Simultaneous triple valve replacements were performed in two patients on January and April 1980 at Seoul National University Hospital. The first case was 17 years old male patient with a history of exertional dyspnea for 7 years. He was in class III by the NYHA functional classification and diagnosed as aortic insufficiency, mitral steno-insufficiency and tricuspid insufficiency. The second case was 46 years old male patient suffered from exertional dyspnea for 5 years, He was in class IV and diagnosed as aortic stenoinsufficiency, mitral stenoinsufficiency and tricuspid insufficiency. Triple valve replacements were performed under the deep hypothermia and pharmacologic cardiac arrest with aortic cross clamping for 80 minutes to 159 minutes. Total extracorporeal circulation time were 197 and 176 minutes respectively. The postoperative courses were uneventful.

Background: Cardiac involvement of Behcets disease is very rate, however, the prognosis of Behcet disease depends on cardiovascular complications. In this article, we described surgical treatment of aortic insufficiency with Behcets disease. Material and Method: From March 1986 to February 1998, we operated on 10 patients of aortic insufficiency with Behcets disease. Male to female ratio was 8 to 2, and age ranged from 21 to 40 years(mean 32.8 years). There were 8 patients with evidence of Behcets disease and another 2 patients had some suspicious findings of Behcets disease(i.e., prosthetic value dehiscence, hypertrophied aortic wall). Adequate preoperative medical treatment for Behcets disease was done in 3 patients. Result: We performed 24 open heart surgeries in 10 patients. Redo value replacements using prosthetic valves were done in 4 patients. Among them, 2 patients were operated on for a second redo valve replacement and one of them operated on for a 4th and 5th operation because of recurrent paravalvular leakage. These 4 patients expired. 1 patient who had undergons tissue value replacement is alive. 1 patient who underwent Cabrol operation expired dut to rupture of graft anastomosis site. We used homografts in 3 patients. In 2 of them, we performed aortic root replacement and subcoronary valve replacement in another patient. The patient who underwent subcoronary valve insertion had remnant aortic insufficiency, so we are closely observing him. We also performed Ross operation in a 24 year old female who suffered severs aortic insufficiency and endocarditis after aortic valvuloplasty. 5 patients are alive and mean follow up duration is 49.0 months. Among them, we used homografts or sutografts in 4 patients. We could observe excellent clinical results in the patients who underwent aortic root replacement using homograft and they were treated medically for Behcets disease. Conclusion: We concluded that adequate preporative diagnosis, clinical suspicion, and periopertive medical treatment for Behcets disease are very important for the result of surgical management of aortic insufficiency with Behcets disease. The use of homograft or autograft was helpful for the healing of anastomosis site and we should carefully observe the long term follow up results.

Aortic annulus size was measured by two-dimensional echocardiography [2DE] in 29 patients undergoing aortic valve replacement or double valve replacement in order to predict prosthetic aortic valve size. Fifteen patients had aortic stenoinsufficiency, eleven had aortic insufficiency, and three had aortic stenosis. 2DE measurements of aortic annulus diameter, as determined from the parasternal long-axis view, demonstrated a high correlation with actual prosthetic valve size implanted at surgery [r=0.85, p<0.05]. 2DE exactly predicted actual prosthetic valve size in 8 of 29 patients [27.6%], was within 1mm of prosthetic valve size in 11 of 29 patients [37.9%], was within 2mm of prosthetic valve size in 8 of 29 patients, and was within 3mm of prosthetic valve size in 2 patients.

The mitral valve replacement with Beall prosthetic valve was performed on three patients, and double valve replacement. aortic and mitral valve, was performed in this department.1) The preoperative studies about the first case were compatible with mitral steno-insufficency.The diseased mitral valve was replaced with the medium sized Beall prosthetic valve under the cardiopulmonary hypass using hypothermic hemodilution technique. The total perfusion time was eighty minutes. Immediate postoperative course was smooth, but this patient was died of asphyxia due to tracheomalacia complicated after tracheostomy 3 months after operation. Autopsy on this patient revealed that no thrombus and no ball variance could be found, and endothelization on the valve cuff was satisfactory. 2) The preoperative studies on the second case were compatible with mitral insufficiency. The diseased mitral valve was replaced with the medium sized Beall prosthetic valve under the cardiopulmonary bypass using hypothermic hemodilution technigue. The total perfusion time was 123 minutes. This patient was discharged in good condition and follow-up study after 16 months revealed the patient had enjoyed healthy life. 3) The preoperative studies about the third case were compatible with aortic insufficiency and mitral stenoinsufficiency. The diseased valves were replaced with type 2 sutureless Magovern aortic valve and the medium sized Beall mitral prosthesis under cardiopulmonary bypass using hypothermic hemodilution technIque and coronary artery perfusion. The total perfusion time was 155 minutes. This patient was discharged in good condition, but thromboembolism was developed 2 months after discharge. 4) The preoperative studies about the fourth case were compatible with mitral insufficiency. The diseased mitral valve was replaced with the medium sized Beall prosthetic valve. The total perfusion time was 132 minutes. The atrioventricular block developed just after operation but converted to normal sinus rhythmn on the third postperative day. The preoperative NYHA functional classification IV was converted to Class 1 or 11 at the time of discharge and this patient enjoyed healthy life. Attendum; The fifth case, nineteen years old male with mital insufficiency underwent Beall valve replacement and his course was uneventful 2 weeks after operation.

Von Hippel-Lindau (VHL) disease is an autosomal dominant hereditary disorder caused by a germline mutation of the VHL gene. It is a multi-systemic disorder that is predisposed to benign or malignant tumors of visceral organs such as hemangioblastoma of the central nervous system, renal cell carcinoma, retinal angioma and pheochromocytoma. We report herein a case of VHL disease that initially manifested with aortic valve insufficiency.
