Surgery for total anomalous pulmonary venous drainage in adults. Case reports and review of eight Japanese patients over 40 years of age.

In the majority of cases, total anomalous pulmonary venous drainage (TAPVD) results in death in infancy or early childhood, with very few cases surviving until adulthood. We report here the surgical correction of TAPVD in two adult patients, a 43-year-old male and 51-year-old female. The postoperative course was uneventful in the two patients, both of whom showed marked improvement of clinical features. The six other surgical corrections of TAPVD in patients over 40 years of age that have been reported in Japan are also reviewed. The favorable results in these cases were associated with the following common factors: 1) unobstructed forms with large drainage veins, 2) large interatrial communication, 3) normal pulmonary vascular resistance with normal or slightly elevated pulmonary artery pressure, 4) low grade, delayed cyanosis, and 5) the supracardiac type of TAPVD.

[Relationship between early peaking of serum myosin light chain 1 level and washout phenomenon of creatine kinase in acute myocardial infarction].

To investigate the serum levels of myosin light chain 1 (MLC1) during the acute phase of myocardial infarction, the MLC1 and creatine kinase (CK) levels were measured in samples from 59 consecutive patients with acute myocardial infarction. The serum concentration of MLC1 increased rapidly, reaching an early peak in 22 of the 59 patients (the MLP + group). Fifteen patients showed rapid increases in MLC1 levels without an early peak (the MLP - group). Serum MLC1 levels remained within normal limits (the MLN group) 10 hours after the onset of symptoms in the remaining 22 patients (but in eight of these serum MLC1 levels were abnormal 16-39 hours after the onset of symptoms). Serum level curves of CK showed a single episode of acute myocardial infarction in all patients. The patterns of MLC1 levels correlated with the washout phenomenon of CK (p < 0.001) and the maximum MLC1 level (p < 0.05). The ratio of serum MLC1 level during the early phase to the maximum level (EMR) decreased in the order of groups MLP+, MLP-, MLN (0.54 +/- 0.28, 0.31 +/- 0.22, 0.13 +/- 0.09, respectively). The EMR was correlated with the washout phenomenon of CK (p < 0.001), but not with the maximum MLC1 level which might reflect the size of the infarction. The patterns of neither MLC1 nor EMR were correlated with the administration of urokinase or the patency of the infarct-related artery at the early phase (within 10 hours of onset).(ABSTRACT TRUNCATED AT 250 WORDS)

[Change in mitral valve area after percutaneous transvenous mitral commissurotomy: prediction of mitral valve restenosis].

Factors indicating changes in mitral valve area after single-balloon percutaneous transvenous mitral commissurotomy (PTMC) were evaluated in 53 patients receiving PTMC by follow up for 3-48 months (mean 18 +/- 12 months) using serial transthoracic echocardiography to measure mitral valve area by planimetry. The echocardiographic scores of the mitral commissures and mitral valve, and other clinical variables were assessed. Mitral valve area showed an immediate increase from 1.1 +/- 0.3 to 1.8 +/- 0.3 cm2 (p < 0.01). There was a small but significant decrease in mitral valve area at follow-up to 1.6 +/- 0.4 cm2 (p < 0.01). Restenosis (a decrease in mitral valve area of more than 25% from immediately after PTMC to follow-up) occurred in nine patients (17%). There was no significant correlation between clinical or echocardiographic features and an increase in mitral valve area immediately after PTMC. The total echocardiographic score of the mitral commissures correlated with the decrease in mitral valve area at follow-up (r = 0.42, p = 0.002). Multiple regression analysis showed the total echocardiographic score of the mitral commissures was the best indicator of a decrease in mitral valve area at follow-up (p = 0.0059). Six of nine patients with restenosis had a commissure score of more than 3, while only five of 44 patients without restenosis had a commissure score of more than 3 (p < 0.01). Mitral valve area increases significantly immediately after PTMC, and decreases significantly at follow-up.(ABSTRACT TRUNCATED AT 250 WORDS)
