  • We experienced a case of aneurysm of the sinus of Valsalva dissecting into the ventricular dseptum. This dissection was induced by paravalvular leakage after aortic and mitral valve replacement. This 37-year-old male was admitted via emergence room due to progressive dyspnea. He had undergone aortic valve replacement(carbomed c" 23 mm) and mitral valve replacement(carbomedic 31 mm) due to aortic regurgitation and mitral regurgitation about 6 years prior to admission and followed up regularly. The diagnosis was made by transthoracic and transesophageal echocardiography and reconfirmed by root aortography. The inlet of the ventricular septal aneurysmal sac was repaired by one layer suture with 3-0 prolene of the endocardium, epicardium and homograft muscle shoulder altogether. Postoperative course was uneventful and the patient was discharged on the 11th postoperative day. day.

  • Takayasu`s disease is an arteritis of unknown etiology involving larger elastic arteries such as aorta and its branches, pulmonary arteries and rarely coronary arteries. Especially, aortic root involvement with the valvular leaflets has been reported in several cases of Takayasu`s arteritis. Recently we have experienced one case of Takayasu`s arteritis involving left subclavian artery, descending aorta, left renal artery and multiple valvular leaflets. The patient was 33 year-old female and admitted with complaints of cough, dyspnea and general weakness. Aortogram revealed extensive type of arteritis showing dilatation of ascending aorta, segmental narrowing of thoracic aorta and Riolan`s anastomosis. Double valve replacement [mitral and aortic valve] and tricuspid valve annuloplasty were performed. The patient made an excellent postoperative recovery and has shown striking improvement in cardiac status, NYHA functional class II eight months after operation.

  • Purpose: This study aimed to analyze changes in QRS duration and cardiothoracic ratio (CTR) following pulmonary valve replacement (PVR) in patients with tetralogy of Fallot (TOF). Methods: Children and adolescents who had previously undergone total repair for TOF (n=67; median age, 16 years) who required elective PVR for pulmonary regurgitation and/or right ventricular out tract obstruction were included in this study. The QRS duration and CTR were measured pre- and postoperatively and postoperative changes were evaluated. Results: Following PVR, the CTR significantly decreased (pre-PVR $57.2%{\pm}6.2%$, post-PVR $53.8%{\pm}5.5%$, P=0.002). The postoperative QRS duration showed a tendency to decrease (pre-PVR $162.7{\pm}26.4$ msec, post-PVR $156.4{\pm}24.4$ msec, P=0.124). QRS duration was greater than 180 msec in 6 patients prior to PVR. Of these, 5 patients showed a decrease in QRS duration following PVR; QRS duration was less than 180 msec in 2 patients, and QRS duration remained greater than 180 msec in 3 patients, including 2 patients with diffuse postoperative right ventricular outflow tract hypokinesis. Six patients had coexisting arrhythmias before PVR; 2 patients, atrial tachycardia; 3 patients, premature ventricular contraction; and 1 patient, premature atrial contraction. None of the patients presented with arrhythmia following PVR. Conclusion: The CTR and QRS duration reduced following PVR. However, QRS duration may not decrease below 180 msec after PVR, particularly in patients with right ventricular outflow tract hypokinesis. The CTR and ECG may provide additional clinical information on changes in right ventricular volume and/or pressure in these patients.

  • Background: Tricuspid valve replacement is very rarely performed procedure and its long-term result is not yet satisfactory. Moreover, it is not well known whether bioprosthesis or mechanical prosthesis is the best selection for artificial valve. We reviewed 72 cases of tricuspid valve replacements in 71 patients between January 1989 and December 1998, trying to analyze the overall results and risk factors for mortality and morbidity. Material and Method: Average age of the patients at the time of operation was 42$\pm$13 years(range 16 to 65 years) and the sex ratio of male versus female was 32/39. Primary diagnosis consisted of 50 cases of aquired valvular heart disease and 18 cases of congenital heart disease, such as Ebstein’s anomaly. 4 cases had isolated tricuspid valve regurgitation. Implanted valves were 69 mechanical prosthesis and 3 bioprosthesis. Concomitant mitral or aortic valve replacements were performed in 50 cases. One patient received concomittant pulmonary valve replacement. Result: There were 7(9.72%) operative deaths and 7(13.0%) late deaths. Actuarial survival at 10 years was 59.2$\pm$7.2%. Prosthetic tricuspid valve thrombosis occurred 11 times in 5 patients. Reoperation for prosthetic tricuspid valve failure was performed in 1 patient. In this case, examination of the explanted prostheses showed that the tricuspid stenosis was the result of valve thrombosis. Among the 47 survivors, 46 patients(98%) were in functional class I or II. Conclusion: In our ten-year experience of tricuspid valve replacement, mortality and morbidity were satisfactory. Mechanical prosthesis in tricuspid position showed comparable clinical results as bioprosthesis.

  • Congenital coronary arteriovenous fistula is relatively uncommon and often associated with additional congenital and acquired heart disease. If coronary arteriovenous fistula is suspected, the diagnosis can be made readily by cardiac catheterization and selective coronary arteriography. Surgical treatment is very satisfactory, with a low mortality and apparent good long term result. Recently, we experienced one case of congenital coronary arteriovenous fistula which was associated with aortic stenosis and regurgitation. The tortuous fistula tract was noted between the left anterior descending coronary artery and the main pulmonary artery. Under the cardiopulmonary bypass, aortic valve replacement[Carbomedics 23mm] and suture closure of the draining orifice of coronary arteriovenous fistula in the main pulmonary artery just above the pulmonary valve were performed, Postoperative hospital course was uneventful and the patient was discharged postoperative 9th day without any problems.

  • Patients with concomitant surgical diseases of the heart and lungs are a therapeutic challenge to cardiothoracic surgeons. A 59-year-old woman underwent right middle lobectomy for lung cancer and redo double valve replacement with tricuspid annuloplasty simultaneously. Concomitant operation is a safe procedure and might allow prompt correction of both conditions, thereby sparing the patient a second major thoracic procedure with its attendant risks.

  • Papillary muscle rupture with severe acute mitral regurgitation is a rare complication of acute myocardial infarction (AMI) that causes pulmonary congestion and cardiogenic shock. Moreover, it has a poor prognosis. Surgical intervention, including revascularization, is indicated; however, surgical mortality remains high. We report the case of an 85-year-old woman with cardiogenic shock from severe acute mitral regurgitation, in whom a hybrid intervention, combining percutaneous coronary intervention with mitral valve replacement via minithoracotomy, was performed after post-infarction papillary muscle rupture. She was discharged in a favorable clinical condition. We describe a novel hybrid intervention for treating a rare complication of AMI, which could minimize surgical invasion in elderly patients, prevent disuse syndrome after the intervention, and improve prognosis. However, mitral valve surgery via minithoracotomy for emergency cases requires technical proficiency, as well as collaboration with other healthcare professionals, and the choice to perform this procedure requires careful consideration.

  • From Aug. 1984 to May 1986, 116 cases of cardiovascular surgery including 85 cases of open heart surgery were performed at Korea Veterans Hospital. There were 108 congenital anomalies and 8 acquired valvular heart diseases. Among 108 congenital malformations 92 operations were done for acyanotic group, and 16 operations for cyanotic group. Thirteen cases of open heart surgery for infants or small children under 10kg of body weight were performed, which occupied 15.3 percent of total open heart surgery done in the same period. Common congenital cardiovascular anomalies were ventricular septal defect [40.7%], patent ductus arteriosus [29.6%], tetralogy of Fallot [12.[%], atrial septal defect [11.1%], and pulmonary stenosis [1.9%] in order of frequency. Valve replacement using lonescu-Shiley or Carpentier-Edwards valve was performed for 8 cases of acquired mitral valve disease, and valve replacement using St. Jude valve was done for a case of patent ductus arteriosus with severe mitral insufficiency. There was no mortality in acyanotic congenital malformations and acquired valve lesions, and 5 cases of mortality in cyanotic congenital malformations. Overall mortality was 4.3 percent for total cases and 5.9 percent for 85 cases of open heart surgery.

  • Fourty-five cases of operation were performed for the correction of tricuspid regurgitation [TR] in Pusan National University Hospital between 1982 and 1991.The mean age of the patients was 32.6 years and female was dominant[M:F=1:2.2].Isolated tricuspid regurgitation was rare and 43 patients underwent concomitant other valvular operation including mitral valve replacement. Functional cause was in 39 cases and organic lesions were found in 6 cases. Operative methods were Kay annuloplasty[29], De Vega annuloplasty[12], and tricuspid valve replacement[4]. Ring annuloplasty was not performed. Operative mortality rate was 11.1%[5/45] and late mortality rate was 6.7%[2/30]. The tricuspid valve surgery itself was not a serious risk factor for hospital death and no heart block nor thrombosis was complicated. By echocardiogram early[within 30 days] and late [mean:4.9years] changes of postoperative TR were evaluated. De Vega annuloplasty seemed to bring better late result than Kay annuloplasty[p<0.05]. In four patients with late severe TR,previously replaced tissue valve degeneration[2], pulmonary hypertension[1] and rheumatic TR[1] were the possible causes. This experience suggests that De Vega annuloplasty can be a reliable method in the majority of patients with moderate-to-severe functional TR.
