Dual isotope protocol using rest thallium and stress MIBI was introduced in Mexico 4 years ago. This protocol reunite the advantages of both radiotracers for the study of myocardial perfusion. We present our experience of the first three years. One thousand six hundred patients were studied with suspected myocardial ischemia; 288 were excluded because of an absence of a proper follow up. In 895 of the 1312 patients a coronariography was performed. Images were evaluated by dividing the heart in 20 segments using a 5 points scale (0 = normal to 4 = absence of perfusion). It was considered a perfusion defect when a segment had a score greater or equal to 2 and the SPECT study was considered abnormal if two or more segments had a MIBI stress score equal or greater than 2. The global sensitivity for diagnosis of ischemia was 96.28%. Dual isotope method is appropriate for the diagnosis of ischemic heart disease. It has a high sensitivity and specificity for the recognition of global coronary disease and for specific coronary territories. This work constitutes the greatest series in Latin America that uses this diagnosis method.","PeriodicalId":75556,"journal":{"name":"Archivos del Instituto de Cardiologia de Mexico","volume":"70 3","pages":"234-40"},"PeriodicalIF":0.0,"publicationDate":"2000-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21796348","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}

Ninety seven patients (36 male and 61 females) underwent occlusion of the PDA. The following variables were compared: age, sex, ductus diameter, morphology, device, occlusion time, residual shunt, multiple device and complications. Data obtained were compared using the Student's test and Chi 2. Median patient age was 7.82 +/- 6.89, forty five patients underwent transcatheter Rashkind-17 closure, 19 patients with Rashkind-12, 18 patients with Coil and 13 patients with Grifka device, in two patients the closure could not be performed. There were differences between the morphology and device used (p = 0.008), between the ductus diameter and device used (p < 0.001). There was immediate closure in 26.7% in the Rashkind-17 group compared with, 57.9% for the Rashkind-12 group, 83.3% for Coil group and of 91.7% for Grifka group. The occlusion within 24 hrs of implantation was 60% with Rashkind-17, 78.9% with Rashkind-12, 94.4% with Coil and 100% with Grifka. Residual shunt persisted for more than a year in 7 patients with Rashkind-17 and 1 with Rashkind 12, (p = 0.001), in 4 patients two devices wore placed. The complications were, 15.5% for Rashkind-17, 26.3% for Rashkind-12, 5.2% for Coil and 30% for Grifka, (p = 0.004), one coil and one Grifka embolized. Transcatheter Coil and Grifka occlusion are more effective in achieving immediate closure than the Rashkind device.

A bolus of 4 gr @ 400 mg/ml was administered via antecubital vein and a second echocardiogram was performed during the ensuing minutes.Results: Between June and July 1998 we studied 16 patients with suboptimal echocardiograms, seven males and nine females, ages 29-77. There were six patients with coronary artery disease (CAD), three with mitral regurgitation (MR), one with dynamic subaortic stenosis, five with right chambers dilatation and one with a left atrial tumor. No patient referred discomfort or had any complication-with Levovist. The mean time of the contrast effect was nine minutes. A better delineation of endocardial borders was observed this allowed better evaluation of wall motion and left ventricular function in patients with CAD. There was Doppler enhancement in patients with MR and subaortic stenosis facilitating its evaluation. We documented atrial septal defect non visualized previously in two of five patients with right chambers dilatation. There was a better delineation of the left atrial tumor.Conclusions: Levovist showed enhancement of all Doppler modalities and facilitated de evaluation of MR, left ventricular function, subaortic stenosis and a cardiac tumor. It was safe and well tolerated.","PeriodicalId":75556,"journal":{"name":"Archivos del Instituto de Cardiologia de Mexico","volume":"70 2","pages":"154-9"},"PeriodicalIF":0.0,"publicationDate":"2000-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21771801","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}

Nowadays echocardiogram plays an important role in the diagnosis. This procedure is able to identify a wide range of malformations. Cardiac catheterization is mainly a therapeutic tool, surgery is now performed much earlier because CHDS are diagnosed sometimes before birth or very early in life. All this advances in the diagnosis and treatment of this group of patients, allows them not only a better quality of life but also the possibility of reaching adulthood and having children. The study of the etiology of CHD is a field that has not evolved as fast as the assessment and treatment. Nowadays we have a larger population of adults with CHD. The discovery of a microdeletion of chromosome 22 q11.2 associated with conotruncal cardiac defects, proves a common etiology for clinical phenotypes and conotruncal malformations. In order to identify, which of these patients share the same etiology and presented with this syndrome, we collected a group that shared not only heart defects of the conotruncal type but also specific phenotypic alterations such as broad nasal bridge, nasal dimple, high palate, and digitalization of the first finger among others. The first two patients studied with FISH technique were positive to monosomy of a locus on chromosome 22. Those patients with CHD of conotruncal type should undergo microdeletion testing so genetic counseling can be offered as well as appropriate treatment in areas such as cardiology and developmental psychology.","PeriodicalId":75556,"journal":{"name":"Archivos del Instituto de Cardiologia de Mexico","volume":"70 2","pages":"148-53"},"PeriodicalIF":0.0,"publicationDate":"2000-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21771899","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}

Seventeen hearts were studied with the segmental sequential system. The situs was solitus in thirteen; dextroisomerism in three and levoisomerism in one. The atrioventricular valves were separated in nine; there was a common atrioventricular valve in eight; straddling of the atrioventricular valve in seven and stenosis in two. The rudimentary right ventricle was to the right side in twelve hearts and to the left side in five. The discordant ventriculoarterial connection was the most frequent (seven), followed by the concordant one (five) and double outlet right ventricle (five). There was pulmonary stenosis in five. The ventricular septum did not reach the crux cordis. The ventricular septal defect was bigger in straddling atrioventricular valves than in valves completely open into the left ventricle, being restrictive in ventriculoarterial concordance. Surgical treatment varies as the complexity of this cardiopathy does, from cardiac septation to palliation procedures. The morphologic knowledge of this cardiac malformation is basic to interpret correctly the diagnostic imaging.","PeriodicalId":75556,"journal":{"name":"Archivos del Instituto de Cardiologia de Mexico","volume":"70 2","pages":"136-47"},"PeriodicalIF":0.0,"publicationDate":"2000-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21771797","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}
