A 52-year-old man was referred to our hospital due to fever and myalgia that occurred 2 weeks earlier. He showed a complete atrioventricular block on his electrocardiogram, and his vital signs were unstable. On his transthoracic echocardiograph, the 1.5 cm vegetation in the aortic valve with severe aortic regurgitation suggested infective endocarditis. His transesophageal enchocardiograph showed abscess in his mitral-aortic intervalvular fibrosa and vegetation was suspected on his anterior mitral valve leaflet. The patient underwent an emergent operation for valve replacement with temporary epicardial pacing. Intraoperatively, the septal leaflet of his tricuspid valve was injured during the debridement of the abscess pocket that was extended to the membranous septum. The aortic, mitral, and tricuspid mechanical valves were replaced with annular reconstruction without complications. After 14 days of intravenous antibiotics, we successfully changed the epicardial pacemaker into a transvenous DDD-type permanent pacemaker by placing a left ventricular lead via the coronary sinus and an atrial lead in the right atrium appendage. The patient was discharged in a tolerable state and was examined uneventfully in our hospital's outpatient clinic for 8 months.

A 50 year old man with acute aortic dissection DeBakey type I, involving right coronary artery and aortic valve, underwent replacement of the ascending aorta and aorto-right coronary bypass grafting. The operative findings showed a large transverse intimal tear was at about 4cm above the aortic valve. The dissection extended out into the proximal right coronary artery. And we found that the right coronary artery originated from the left sinus of Valsalva, run transversally in the aortic wall, with partial rupture. Postoperatively he had no ischemic cardiac symptoms and neurologic complications. He was discharged on postoperative 9th day with good result.

Aneurysm of the sinus of Valsalva is an uncommon cardiac anomaly, usually congenital in origin, which may occur as an isolated defect or in conjunction with other cardiac malformation. This report is a case of a ruptured sinus of Valsalva aneurysm with ventricular septal defect in a 18-year-old female patient who complained progressive exertional dyspnea. She underwent operative management using total cardiopulmonary bypass. The fistula originated from the right coronary sinus and ruptured into the right ventricle and coexistent lesion was supracristal ventricular septal defect. The repair was done through aortic and right ventricular approach. The ruptured sinus of Valsalva was closed with pledget suture and the ventricular septal defect was closed with patch. The postoperative result was good.

Here, we present a case of ruptured sinus Valsalva aneurysm with fistulous communication between the right coronary aortic sinus and the right ventricle in 8 year old boy. Ruptured sinus Valsalva aneurysm is rare. And several reports are describing its pathophysiologic features, clinical findings and management. This patient was asymptomatic and the physical examination revealed palpable thrill and Grade III pansystolic murmur at the 3rd and 4th intercostal space along the left sternal border. There was an oxygen step up from right atrium into right ventricle on the cardiac catheterization reports. On 15th July 1981, an open heart surgery was performed and we found ruptured right coronary sinus Valsalva aneurysm into the right ventricle, which was managed successfully by doing direct pledget sutures. The postoperative course was uneventful.

Supravalvular aortic stenosis may be defined as an obstructive congenital deformity of the ascending aorta which originates just distal to the level of the origin of the coronary arteries. It may occur in several different anatomical form. Three type have been described; the hourglass, the hypoplastic and the membranous type, each term identifying the gross characteristic of the lesion causing by the aortic obstruction. Non cardiovascular condition commonly associated with supravalvular aortic stenosis are mental retardation, facial anomalies, hypercalcemia, etc. The diagnosis can be established preoperatively by left heart catheterization and selective angiography. Recently, we experienced a case of multiple localized supravalvular aortic stenosis involving, just above the sinus Valsalva and just proximal of the innominate artery. The surgical correction which was performed by a vertical incision across the each narrowing of aorta with replacement of diamond shaped double velour Woven Dacron patch under the CPB. He was discharged without any event.

A 42 year old male was operated with aortic root abscess and pseudoaneurysm. Aortic valve vegetations which measured $8\times5$ cm and root abscess were removed and debrided. We reconstructed root and noncoronary sinus with autopericardium. Antibiotics were administered for 4 weeks. In general, Aortic root abscess recurs frequently and mortality is high. It is usually requires early surgical eradication with antibiotics medication.

Complete and optimal visualization of the mitral apparatus is a prerequisite for accurate repair or replacement of the mitral valve. A vertical left atriotomy just posterior to the interatrial groove is the most commonly used approach. However,exposure can be difficult under certain circumstances,such as small left atrium or reoperation. Other approaches have been advocated to deal with this difficult situations. We used an extended transseptal approach in 10 patients and good clinical results and excellent educational effects were obtained. The extended transseptal approach combines two semicircular atrial incisions circumscribing the tricuspid and mitral annuli anteriorly and superiorly,allowing exposure of the mitral valve by deflecting the ventricular side using stay sutures. The right atrium is opened anteriorly along the atrioventricular sulcus. The atrial septum is incised vertically through the fossa ovalis. Right atrial and septal incisions are joined at the superior end of the interatrial septum and extended across the dome of the left atrium to the left atrial appendage. The mitral valve was replaced in all 10 patients. Four of 10 patients had other simultaneous valve procedure: one had aortic valve replacement: 2 underwent tricuspid annuloplasty: 1 had aortic valve replacement and tricuspid annuloplasty. There was no hospital death and complication. Among the 5 patients who had atrial fibrillation preoperatively,4 had atrial fibrillation postoperatively,1 converted to sinus rhythm. The five patients who were in normal sinus rhythm preoperatively remained in sinus rhythm after replacement. A review of our results with this approach confirms the efficacy and safty of this method. So we recommanded this approach for routine mitral valve procedure,especially difficult situations,such as a small left atrium or the redo operation.

Background: Dissection flaps in acute type A aortic dissection typically extend into the root, most frequently into the non-coronary sinus (NCS). The weakened root can be susceptible not only to surgical trauma, but also to future dilatation because of its thinner layers. Herein, we describe a new technique that we named the "neo-adventitia" technique to strengthen the weakened aortic root. Methods: From 2012 to 2016, 27 patients with acute type A aortic dissection underwent supracommissural graft replacement using our neo-adventitia technique. After we applied biologic glue between the dissected layers, we wrapped the entire NCS and the partial left and right coronary sinuses on the outside using a rectangular Dacron tube graft that served as neo-adventitia to reinforce the dissected weakened wall. Then, fixation with subannular stitches stabilized the annulus of the NCS. Results: There were 4 cases of operative mortality, but all survivors were discharged with aortic regurgitation (AR) classified as mild or less. Follow-up echocardiograms were performed in 10 patients. Of these, 9 showed mild or less AR, and 1 had moderate AR without root dilatation. There were no significant differences in the size of the aortic annulus (p=0.57) or root (p=0.10) between before discharge and the last follow-up echocardiograms, and no reoperations on the aortic roots were required during the follow-up period. Conclusion: This technique is easy and efficient for reinforcing and stabilizing weakened roots. Furthermore, this technique may be an alternative for restoring and maintaining the geometry of the aortic root. An externally reinforced NCS could be expected to resist future dilatation.

Aneurysm of the sinus of Valsalva is fairly rare. Between 1987 and 1994, we operated on a total of 12 cases of aneurysm of the sinus of Valsalva at the Inje University Seoul Paik Hospital. This represents 0.7% of all cardiac operation under cardiopulmonary bypass. There were eight male and four female patients aged from 8 to 38 years(mean, 19.2 years). 8 of 12 patients had ruptured aneurysms. The origin of aneurysm of the sinus of Valsalva was the right coronary sinus in 10(83. 3%), and the noncoronary sinus in 2(16.6%). In ruptured aneurysm, the origin was the right oronary sinus in 6, and the noncoronary sinus in 2. The aneurysms originating from the right coronary sinus ruptured into the right ventricle in 5, and into both the right atrium and right ventricle in 1. The aneurysms originating from the noncoronary sinus ruptured into the right ventricle in 1, and into the right atrium in 1. Associated congenital cardiac defects included ventricular septal defect in 10(83.3%) patients 39 cases of these were associated with the aneurysms of the right coronary sinus), aortic regurgi- tation in 3 (all of these had an additional ventricular septal defect), mitral regurgitation in 1, and double chambered right ventricle in 1. No hospital deaths occurred, although one late death occurred as a result of endocarditis 15 months after the first operation. The mean follow-up period was 29 months, range from 4 to 60 months. Eleven patients except one late death were in New York Heart Association class 1. Due to the low mortality risk o( an operation for aneur sm of the sinus of Valsalva, a ruptured aneurysm of the sinus of Valsalva should be corrected surgically when the diagnosis is mane, and unruptured aneurysm of the sinus of Valsava with complication should also be operated. In most cases the aorta was opened to examine the morphology of the aneurysm and the aortic cusps, and an associated aortic valve defect should be corrected simultaneously.

Ninety patients underwent mitral valvular heart surgery associated with or without aortic valve surgery and subjected to a clinical study in relation to their control of postoperative atrial fibrillation. There were 26 males and 64 females ranged in age from 16 to 56 years with a mean of 35.2 years. Systemic arterial embolizations were observed in 11 patients [12.2%]. Four patients of them were in normal sinus rhythm and 7 in atrial fibrillation. Out of these, left atrial thrombi were found only in 2 at the operation. Intraoperatively confirmed left atrial thrombi were in 16 patients [17.7%] of all 90 patients: Eleven patients occurred at the age of more than 40 years, 14 were in atrial fibrillation and 2 only had previous episodes of systemic arterial embolization. Sixty three patients underwent isolated mitral valve surgery [OMC 28, MVR 35] and 27 patients associated with aortic valve surgery along with mitral valve [OMC+AVR 13, MVR+AVR 14]. Preoperatively, 44 patients [48.9%] were in normal sinus rhythm. Of them, 35 patients [79.5%] revealed normal sinus rhythm thoroughly after operation without any aid of digitalis or quinidine and 5 patients [11.4%] restored normal sinus rhythm with digitalization alone. Other 3 patients converted to normal sinus rhythm with the addition of quinidine, however, in 1 patient who was resistant to quinidine therapy, electrocardioversion was carried out on the postoperative third week showing normal sinus rhythm. Thus, the most atrial fibrillations that occurred for the first time in the postoperative period, were able to reverted to normal sinus rhythm responding well to antiarrhythmic therapy. Preoperatively, 46 patients [51.1%] were in atrial fibrillation. Of them, only 5 patients returned to sinus rhythm after operation without any aid of digitalis or quinidine and other 5 restored normal sinus rhythm with digitalization: namely 2 restored within early postoperative period and 3 after more than 3 months. Eight patients well responded to quinidine therapy showing normal Sinus rhythm. So far, 25 patients have remained in persistent atrial fibrillation on 6 to 36 months follow-up. In view of these, 17 patients [68%] were over 40 years of age, 22[80%] had long duration of symptom over 5 years and 10[40%] have had atrial thrombi before operation. Left atrial dimension were still more than 40mm in 21 patients on follow up M-mode echocardiogram. One month after operation, 87 hospital survivors were improved by at least one functional NYHA class. There were 3 operative deaths [3.3%, bleeding 1, LCOS 2] and 4 late deaths [LCOS 1, valve thrombosis 1, late bleeding 1, fulminant hepatitis 1] during follow-up period. According to our limited experience, we may conclude that better results will be expected with the addition of quinidine therapy judiciously in the cases of postoperative persistent atrial fibrillation who were aged or had longer history of symptom and left atrial thrombi.
