  • Hemoptysis occurs quite frequently as a consequence of mitral stenosis, but massive, lirE threatening pulmonary hemorrhage is distinctly unusual. We report a 30 year old female who underwent cmcrgcncy rcdo double valve replacement for intractable pulmonary hemorrhage. she underwent mitral valve replacement (lonescu Shirley 27 mm) due to rheumatic valvular heart disease in 1984 and tricuspid valve annuloplasty (Carpentier's rlng 30mm) two years later She was admitted for massive hcmoptysis and dyspnea on the 26th of December, 1995. Medical treatment including transarterial embolization was given but was not satisfactory. Emergency valve replacement (Mitral valve , 51. Judc 29mm and tricuspid valve ; 51. Jude 33mm) was performed and hemoptysis was controlled dramatically 24 hours after surgery.

  • The common causes of organic mitral regurgitation (MR) include mitral valve prolapse (MVP) syndrome, rheumatic heart disease, and endocarditis. MR also occurs secondary to dilated cardiomyopathy and coronary artery disease. In acute severe MR, the hemodynamic overload often cannot be tolerated, and mitral valve repair or replacement must be performed immediately. We report herein a case of severe MR due to coronary vasospasm that was confirmed via ergonovine echocardiography in a 70-year-old man. He was scheduled to undergo mitral valve surgery, but it did not push through and he was put on medical therapy.

  • As a percutaneous technique for the reduction of mitral regurgitation, the MitraClip system (Abbott Vascular, Abbott Park, IL, USA) for transcatheter edge-to-edge repair of the mitral valve was developed in 1998 and first used in 2003. Its main advantage is being less invasive than surgery, because it can be performed through a transcatheter approach without any hemodynamic compromise. Recent studies have shown that this procedure reduces symptoms and improves functional capacity with low complication rates. Two randomized clinical trials have investigated the use of this technique for functional mitral regurgitation. The Korean Ministry of Food and Drug Safety approved its use for degenerative mitral regurgitation in 2019, and this procedure started to be performed in Korea in January 2020. Its use for functional mitral regurgitation was also approved in Korea in 2020. In this article, recent evidence on transcatheter edge-to-edge repair of the mitral valve and our initial experiences in Korea will be reviewed.

  • Total 20 cases of reoperation for mitral vavular disease, which had been performed during the period from May 1983 till October 1991, were reviewed. This study contained 1 case of previous balloon valvuloplasty and 1 case of death with bleeding from right ventricle during sternal reenrty. The average time intervals between reoperation and previous operation was 19 years in closed mitral commissurotomy[n=4], 7 years and 2 months in mitral valve replacement[n=10], 1 year and 8 months in mitral valvuloplasty[n=4], 3 years and 10 months in open mitral commissurotomy [n=2]. The cause of reoperation in closed mitral commissurotomy was progression of the disease, and residual stenosis with progression was the cause in open mitral commissurotomy cases. Technical failure might be the cause in the cases of valvuloplasty. In prosthetic valve replacement group the causes of reoperation were primary failure. Also two cases of suggested valve thrombosis and one case of failure of tricuspid annuloplasty was noted in prosthetic valve replacement group. The used valves for reoperation were Ionescue-Shiley in 3 cases, Bjork-Shiley in 6 cases, St. Jude Medical in 2 cases and CarboMedics in 8 cases. The mortality rate was 20%[n=4] and the causes of death were low output syndrome in 1 case, multiple organ failure in 2 cases and bleeding in 1 case during sternal reentry. During follow up 1 case of sudden death was observed.

  • A total and consecutive 156 patients have undergone cardiac valve surgery including 13 closed mitral commissurotomy, 13 open mitral commissurotomy, one mitral annuloplasty, 75 mitral valve replacement, one aortic annuloplasty, 24 aortic valve replacement, 3 tricuspid valve replacement, 25 double valve replacement and one triple valve replacement. 155 prosthetic valves were replaced in a period between September 1976 and August 1985. There were 68 males and 88 females with age range from 8 to 69 yrs [mean 36.5 yr]. Out of replaced valves, 61 was tissue valve including 54 Carpentier-Edwards, and 4 was mechanical valves including 74 St. Jude Medical, and the position replaced was 101 valves for mitral, 46 for aortic and 8 for tricuspid. Single valve replacement in 102 cases, double valve replacement in 25 cases [17 for AVR+MVR, and 8 for MVR+TVR], and only one case was noted in the triple valve replacement. Early mortality within 30 days after operation was noted in 11 cases [7%]; 7 after MVR, 2 after DVR, and each one after open mitral commissurotomy and mitral annuloplasty. Cause of death was valve thrombus, cerebral air embolism, low output syndrome, uncontrollable arrhythmia, parapneumonic sepsis, acute cardiac tamponade and left atrial rupture. 7 late deaths were noted during the follow-up period from 1 to 104 months [average 48 month]; three due to valve and left atrial thrombus formation, two due to CVA from overdose of warfarin, and each one due to congestive heart failure and chronic constrictive pericarditis, Anticoagulants after prosthetic valve replacement were maintained with warfarin, dipyridamole and aspirin to the level of around 50% of normal prothrombin time in 79 cases, and Ticlopidine with aspirin in 47 cases to compare the result of each group. There were 11 major thromboembolic episodes including 3 deaths in the warfarin group. Two cases of CVA due to overdose of warfarin was noted in the warfarin group. In the ticlopidine group, there was only one left atrial thrombus confirmed at the time of autopsy. Among the survived 138 cases, nearly all cases[136 cases] were included in NYHA functional class I and II during the follow-up period. In conclusion, surgical treatment of the cardiac valve disease in 156 clinical cases revealed excellent result with acceptable operative risk and late mortality. Prevention of thrombus formation with anti-platelet aggregator Ticlopidine has better result than warfarin group presently with no specific side effect such as bleeding or gastrointestinal trouble.

  • From 1958 to October 1977, 294 cases of acquired heart disease were operated. There were 68 cases of pericardium, 3 trauma, 2 foreign body, one cardiac thrombus, 3 atrial myxoma, 2 left atrial and 1 right atrial, 2 Budd-Chiari syndrome, and 214 valvular heart disease. Out of 214 cases of valve operation 73 valves were replaced in 64 patients. Male to female ratio was 1.46: 1. The youngest age was 14 years in male and 18 in female. The oldest was 54 years in male and 52 in female. Fifty-five cases of single valve were replaced, consisting of 47 mitral and 8 aortic valves. There were 9 double valve replacement cases which consist of 7 mitral and aortic and 2 mitral .and tricuspid valves. Six varieties of prosthetic valves, 3 ball and 3 disc types and 3 kinds of xenograft tissue valves were utilized. Beall, BjSrk-Shiley and Starr-Edwards prosthetic valves and Hancock valves were used mainly. For single valve 34. 5% and for double valve replacement 44% mortality were noted. There were 23 operative deaths out of 64 patients, over all mortality rate of 36.9%. Mortality for mitral valve replacement was 29.5%. But in recent 12 consecutive cases one death occurred, showing 8.3% mortality. In earlier days thrombocyte anti-adhesive drug dipyramidole-persantin-aspirin and/or SP 54 were adminstered. But in recent cases after heparinization, coumadin and Persantin were prescribed routinely.

  • Recently, a new method of evaluating left atrial size called vertebral left atrial size (VLAS) was introduced in dogs. Total 155 dogs were examined at the Veterinary Medical Teaching Hospital of Chungnam National University. In this study, myxomatous mitral valve disease (MMVD) stage and VLAS showed a significant correlation in those dogs. Also, the relationship between C-reactive protein (CRP) and VLAS has yet to be examined. We found a strong positive correlation between VLAS and CRP-a significant increase in CRP was observed with increasing VLAS values. Thus, it would be beneficial to measure VLAS besides employing the current radiological and echocardiographic methods when evaluating heart size. Measuring VLAS could be an additional diagnostic tool for diagnosing MMVD in dogs.

  • Myxomatous mitral valve disease (MMVD) is a degenerative disease of the valve leaflets, causing left atrial dilatation and eccentric hypertrophy of the left ventricle by hemodynamic instability. Red cell distribution width (RDW) is a hematologic parameter that indicates the variation of red blood cell volume and size, reflecting anisocytosis. Human studies have found that anisocytosis is associated with poor prognosis in heart disease patients, and recent veterinary studies have also confirmed that the increase in RDW is associated with high mortality in MMVD patients. Medical records of 37 Maltese dogs with MMVD were retrospectively reviewed. When comparing RDW among the MMVD stage groups, there was a significant difference between stage B1, B2 and C. A significant and strong correlation between RDW and the left atrial-to-aortic ratio was identified. RDW was significantly correlated with the reticulocyte count independent of hematocrit, and the reticulocyte count exhibited a significant increase at stage C. This suggests that the congestive heart failure secondary to MMVD could be a contributory factor leading to an elevation in RDW. In conclusion, elevated RDW may associated with left atrial enlargement and progression of MMVD.

  • Mitral regurgitation (MR) is the most common heart disease in small-breed dogs. Mitral repair, which comprise artificial chorda tendineae implantation and mitral annuloplasty, has become the mainstay of treatment in the veterinary field. We report on two small dogs who underwent mitral repair surgery for MR. A Hegar dilator was used during mitral annuloplasty for accurate and reproducible surgery. In both cases, mitral regurgitant flow almost disappeared after surgery, and clinical signs improved. The treatment regimen was terminated 3 months after the surgery. We concluded that using a Hegar dilator may facilitate mitral valve repair surgery.

  • To see the change of pulmonary arterial pressure after mitral valve replacement, postoperative cardiac catheterization and echocardiographies were performed in 12 patients of mitral valvular disease with pulmonary hypertension[systolic pulmonary arterial pressure>50 mm Hg]. The mean follow-up duration was 35.4[range: 15-47] months per patient. The following results were obtained. 1] Preoperative systolic pulmonary arterial pressure value of 66.17\ulcorner10.73mmHg decreased significantly to 29.17\ulcorner6.86mmHg postoperatively[p<0.01]. 2] Preoperative Pp/Ps value of 0.67\ulcorner0.13 decreased significantly to 0.28\ulcorner0.06 postoperatively[p<0.01]. 3] Preoperative PAWP value of 29.00\ulcorner4.02mmHg decreased significantly to 9.92\ulcorner4.27 mmHg postoperatively[p<0.01]. 4] Preoperative LAD value of 5.58\ulcorner1.20cm decreased significantly to 4.37\ulcorner0.67cm postoperatively [p<0.01]. In conclusion, pulmonary arterial hypertension secondary to mitral valvular disease could be reduced to normal range after successful mitral valve replacement.
