A case of mitral stenosis with left atrial thrombus which rapidly arose and reduced within a month was reported. A 61-year-old female was admitted to our hospital on November 14, 1986 because of a syncopal attack due to ventricular tachycardia. On admission she had typical auscultatory signs of mitral stenosis, mild hepatomegaly and no neurological abnormality. Laboratory findings included coagulation studies were normal, and atrial fibrillation was noted on ECG. Heart catheterization revealed low cardiac output, the mitral orifice area to be 2.4 cm2 and left ventriculography showed mild mitral regurgitation. Ventricular tachycardia was controlled following improvement of heart failure. On two-dimensional echocardiography performed on December 24, left atrial thrombus was revealed which was not detected on December 3. Through the continuous administration of warfarin and aspirin to prevent the thrombus' growth, it markedly reduced in size, from 3 x 2 x 4.5 cm on December 24, 1986 to 1.5 x 1 x 2.5 cm on January 30, 1987 without systemic embolism. Then a mitral valve replacement and a left atrial thrombectomy were performed on February 3, with the removal of a red thrombus, partially organized, measuring 1 x 0.7 x 2.5 cm. This case is unique in its clinical outcome and further investigation is necessary for the management of patients as our case.

The factors associated with survival in 40 neonates (age less than 28 days) with critical aortic stenosis undergoing either open (22 patients) or closed (18 patients) transventricular aortic valvotomy were reviewed. Significant adverse correlates with survival included evidence of poor perfusion preoperatively (low pH, greater than Grade 2/6 soft ejection systolic murmur) and marked congestive heart failure (hepatomegaly, cardiomegaly, elevated left atrial pressure). Congenital mitral stenosis (anulus less than 11 mm), a small aortic anulus (less than 6.5 mm), and failure to achieve an adequate aortic orifice (greater than 6 mm), at operation were identified as factors associated with increased mortality. Initial perioperative survival was better with closed aortic valvotomy. However, there was no significant difference in overall operative survival between closed (9/18, 50%) and open (8/22, 36%) aortic valvotomy (p = 0.26). The incidence of early reoperation (less than 1 year of age) was greater in perioperative survivors undergoing closed valvotomy (7/13, 54%) rather than open valvotomy (1/10, 10%) (p less than 0.05). In conclusion, long-term survival among patients with critical neonatal aortic valve stenosis remains disturbingly low (13/40, 32%) and has not significantly improved over the past 20 years.

Rheumatic mitral valve disease is not infrequently associated with tricuspid regurgitation (TR). To determine the fate of TR following closed mitral valvotomy (CMV), we examined the records of 23 patients with variable degrees of TR and significant mitral stenosis (MS). Based on angiocardiographic assessment of TR, patients were divided into two groups: group 1 (15 patients) had mild-to-moderate TR, while group 2 (eight patients) had severe TR. After valvotomy, dyspnea lessened in all patients. Right ventricular (RV) failure signs (jugular venous distension and hepatomegaly) and the amounts of diuretics used diminished in 12 of 15 patients in group 1. Group 2 patients showed insignificant improvement at one-year follow-up period. Cardiac recatheterization was performed in four of group 2 patients three to five years later primarily for persistence of RV failure signs. The mitral valve areas varied from 1.4 to 2.7 cm2. There was mild mitral regurgitation in two patients. There was no deterioration of the left ventricular ejection fraction, but TR was at least moderate in all cases.

From 1963 through 1991, 1037 patients underwent reoperative valvular procedures. The 478 patients having reoperations for either failed bioprosthetic (n = 212) or mechanical (n = 266) valves were evaluated. There were 210 male (44%) and 268 female (56%) patients. The mean age at reoperation of the patients in the bioprosthesis group was 59.7 years and and that in the mechanical valve group was 56.1 years (p = 0.0006). The mean interval to the time of reoperation was 84.7 months in the mechanical valve group and 74 months in the bioprosthesis group. There was no difference between the two groups in the functional class at reoperation. More severe mitral valve stenosis and incompetence, more severe aortic valve stenosis, and higher right ventricular and pulmonary arterial pressures were noted in the bioprosthesis group than in the mechanical valve group. Hemolysis (p = 0.05) was more prevalent in the patients with mechanical valves than in the ones with bioprostheses. A longer aortic occlusion time (p = 0.0001) and longer cardiopulmonary bypass time (p = 0.0001) were required for the reoperations in the bioprosthesis group. The operative mortality was 13.2% for the bioprosthesis patients and 12.4% for the mechanical valve patients. The risk factors for hospital death included the cross-clamp time (p = 0.0001), the functional class (p = 0.00001), the presence of ascites (p = 0.02), hepatomegaly (p = 0.002), and decreasing ejection fraction (p = 0.05). We conclude that mechanical valve failures do not produce catastrophic events resulting in poor reoperative results.

A 59-year-old man had undergone aortic and mitral valve replacement (DVR) for rheumatic aortic and mitral valve stenosis 15 years ago. At that time, echocardiography did not detect tricuspid regurgitation (TR), and catheterization data showed right atrial pressure v wave of 8 mmHg and pulmonary artery pressure of 27/12 (17) mmHg. One year after DVR, hepatomegaly and jugular venous dilatation appeared, and after 5 years edema of both legs became apparent. After 7 years, chest X-ray showed an increase of cardio-thoracic ratio, and for the first time, echocardiography detected mild TR. Fifteen years after DVR, severe general fatigue, shortness of breath and hepatomegaly could not be controlled with medication. Catheterization data showed right atrial pressure v wave of 23 mmHg and pulmonary artery pressure of 28/13 (17) mmHg. Right ventriculography showed progression of severe TR. Tricuspid valve replacement (TVR) was performed using a St. Jude Medical 31 M mechanical valve under natural cooling and heart beating. The tricuspid valve was only slightly thickened and no subvalvular abnormalities were seen other than a severely dilated tricuspid annulus. Postoperative course was uneventful and he was discharged 44 days after the TVR. He is currently doing well 6 years after the TVR. All terms, he did not have pulmonary hypertension or left-side heart problems. We suspect that the cause of TR was not secondary, and was included in the category of isolated TR. If the left heart is completely treated, as in this case, it is important to follow-up for signs of right heart failure, before TR is detected.

A 59-year-old man underwent closed mitral commissurotomy for mitral stenosis at the age of 19 years, and mitral valve replacement (MVR) with a Hancock standard bioprosthesis and tricuspid annuloplasty at the age of 40 years. Two years after the second operation, the patient developed human T-lymphotropic virus type-1 infection, manifesting as myelopathy/tropical spastic paraparesis, and has required steroid therapy for 17 years. He was well for 18 years after the MVR, but has recently developed severe congestive heart failure, orthopnea and enlarged liver. Doppler echocardiography showed severe transvalvular regurgitation of the prosthesis and tricuspid valve. The patient underwent re-MVR with a 27 mm St. Jude Medical prosthesis, and tricuspid annuloplasty. The surgery was well tolerated, without any significant infectious complication. Some tears and perforations were found in the leaflets of the explanted bioprosthesis, but soft X-ray analysis showed minimal calcification. Mild changes and longer durability of the bioprosthesis may be related to the long-term use of steroid therapy.
