From January 1990 to February 1993, 60 patients with DCRV were identified among 1,094 patients with congenital defects of the heart who had open-heart surgery in our hospital. Thirty-six patients were males, and 24 were females, with a mean age of 9.3 years (from 3 to 28 years). Various cardiac anomalies were found to be associated with DCRV. The most common was ventricular septal defect (VSD); 52 patients (86.7%) had VSD, and 6 (10%) had other cardiac lesions. Aims: This study summarises our experience in diagnosing DCRV and surgical correction of the anomaly. Methods: Preoperative diagnosis of DCRV depended mainly on 2-dimensional echocardiography, cardiac catheterisation and cineangiography. Surgical correction consisted of resection of anomalous muscle bundles and correction of associated anomalies through a right ventriculotomy. Results: There was 1 hospital death (1.7%); 59 patients survived (98.3%). The pressure gradient of the right ventricle decreased from 49±23 mmHg (mean±SD) preoperatively to 16±6 mmHg postoperatively (p < 0.001). Patients were followed for 0.3 to 3 years (1.8±0.9 years). No major symptoms were documented at follow-up. Conclusion: Excellent results were obtained with surgical correction of DCRV and related anomalies.</p></div>","PeriodicalId":101219,"journal":{"name":"The Asia Pacific Journal of Thoracic & Cardiovascular Surgery","volume":"5 1","pages":"Pages 14-17"},"PeriodicalIF":0.0,"publicationDate":"1996-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1324-2881(96)90004-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72879661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compared the effects of retrograde with antegrade cardioplegia on the recovery ventricular function inpatients undergoing coronary artery surgery. Two groups of similar age, left ventricular function and extent of disease received either retrograde (RC) or antegrade (AC) multidose cold-blood cardioplegia. A right ventricular rapid-response catheter measured right ventricular haemodynamics before and after bypass. Needle thermistors recorded intramyocardial temperatures in the right ventricular free wall, the left ventricular free wall and the septum. There were no differences in bypass times, ischaemic times, inotrope requirements or arrhythmia frequency between the 2 groups. RV haemodynamics were similar in both groups before bypass. Immediately after bypass the RV end diastolic volume index was lower in the retrograde group than in the antegrade group, and RV ejection fraction was higher. This indicates better RV preservation with retrograde cardioplegia early after bypass. By 30 min after bypass all haemodynamic variables had returned to baseline values in both groups. Retrograde cardioplegia provided effective cooling in all areas of the heart. The mean time to achieve electromechanical quiescence was longer with retrograde cardioplegia, and a larger total volume of cardioplegia was required. Except for a minor advantage for RC soom after bypass, this study suggests that RV protection during coronary artery surgery is the same whether retrograde or antegrade cardioplegia is used. The time taken o achieve diastolic arrest with retrograde cardioplegia may presuade surgeons that combination of antegrade and retrograde cardioplegia remains the most satisfactory technique.</p></div>","PeriodicalId":101219,"journal":{"name":"The Asia Pacific Journal of Thoracic & Cardiovascular Surgery","volume":"5 1","pages":"Pages 9-13"},"PeriodicalIF":0.0,"publicationDate":"1996-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1324-2881(96)90003-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82079062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
