Nursing process for a preschooler after intraventricular septal defect closure surgery in the Cardiovascular Intensive Care Unit of a Lima Institute

Congenital heart disease due to ventricular septal defect is a serious congenital defect, most of the time, and although exceptional, it can also be acquired after rupture of the interventricular septum in an acute myocardial infarction. The objective was to manage the nursing care process in a post-operative preschool patient. The study had a qualitative approach, single case type, the methodology was the nursing care process, the assessment stage was carried out through the assessment framework of Maryori Gordon's 11 functional patterns, the diagnostic stage was developed based on To taxonomy II of NANDA I, nursing diagnoses were identified, prioritizing three of them: Decreased cardiac output, ineffective tissue perfusion and dysfunctional ventilatory response to weaning according to the SSPFR format (signs and symptoms, problem, related factor/risk factor/ associated to); Likewise, the planning stage was carried out taking into account the NOC Taxonomy, NIC, in the execution stage the care was administered and the evaluation was given by the difference in final and baseline scores respectively. A change score of +1, 0, +1 was obtained in the results. In conclusion, the nursing care process for the patient was managed that allowed quality care to be provided to the patient

Preliminary Results of Ventricular Septal Defect Surgery in Festoc Center in Bamako

Interventricular septal defects are dehiscences of the interventricular septum connecting the systemic and pulmonary circulations. The aim of this study is to report the preliminary results of the first series of intraventricular septal defects managed at the Festoc centre in Bamako. This is a mono-centric, descriptive retrospective study taking place at the FESTOC Centre in the period from 10 September 2018 to 30 April 2023. Patients of any age and sex, operated for IVC were included. Patients operated abroad were not included. We recorded 74 cases of IVC, i.e. 23.19% out of 300 cases. 61% of the patients were male, with a sex ratio of 1.56. The average age was 11 years. Symptoms were dominated by dyspnoea and recurrent bronchitis in 67.21% and 49.18% respectively. Peri-membrane and admission topography were dominant, with rates of 84% and 10%

Severe aortic insufficiency secondary to infective endocarditis in a patient with intraventricular septal defect, case report

Background: infective endocarditis is a septic condition predominantly of bacterial origin, although there is a fungal etiology of the native valvular endothelium of the heart, it is a disease associated with high mortality and complications, despite advances in its approach, its incidence has not decreased in the last 30 years. Case report: 30-year-old black female patient, housewife, with a personal history of intraventricular septal defect. She went to the on-call department for presenting high fever at any time of the day accompanied by chills, with joint pain. She had undergone a curettage due to the presence of a fetal ovum. Three days prior to this, she had a fever of 38 degrees Celsius with no specific time of day, accompanied by chills, which was easily relieved with sodium metamizole. The fever persisted daily, which led to several hospital admissions, after which she was discharged home with no diagnostic cause. She was readmitted due to a chronic febrile syndrome, to which joint pain was added. Medulogram was performed and was not useful, suggesting iliac crest biopsy to rule out anarco-proliferative processes, and antimicrobials were not administered during this time. Conclusions: infective endocarditis on native valves with negative blood cultures remains a challenge, despite medical advances in recent decades, and due to demographic changes of patients and the disease, it remains a complex pathology with high morbidity and mortality

The possibilities of computed tomography heart-axis-oriented multiplanar reformations in diagnostics of common arterial trunk

The possibility of using multiplanar reformations oriented on the axis of heart in diagnosing the common arterial trunk with X-ray computed tomography is substantiated. Examination data of 140 patients aged 1-19 days of life, 3030-3890 g body weight with conotruncal congenital heart diseases was analyzed, and common arterial trunk was detected in 7 patients (4 - boys, 3 - girls). In 5 (72%) patients, it developed mainly from the morphological right ventricle, 1 (14%) - completely from the morphologically right ventricle, and 1 more (14%) - evenly located above the ventricles. In four (57%) cases, the trunk valve had three leaflets, in two (28,5%) cases - two, in one (14,5%) case - four. All the patients had mitral-semilunar fibrous prolongation, intraventricular septal defects, doubled coronary arteries system, and the pulmonary arteries had their origin from ascendant part of common trunk. Pulmonary arteries had also their own common trunk in 4 (57%) cases, separate estuary in 3 (43%) cases. Aortic arc abnormalities included dextral aortic arc (2 cases), discontinuity of aortic arc (1 case), discontinuity of fourth aortic arc with persistence of fifth left aortic arc (2 cases). In general, computed tomographic angiocardiography heart-axis-oriented multiplanar reformations permit full and correct assessment of heart and main vessels, which is important for surgical treatment planning in congenital heart diseases.

Oral exposure of male and female mice to formulations of organophosphorous pesticides: congenital malformations

Birth outcome was studied in pre-partum litters of mice exposed to oral doses of organophosphorous pesticides at low and high concentrations before mating. Exposed and unexposed pregnant dams were delivered by Caesarean section 1 day before partum, the fetuses were collected, counted and weighed, and the numbers of resorptions were recorded. Live litter sizes were non-significantly higher in all the exposed groups compared with the control group. The numbers of resorptions were significantly higher in all the exposed groups than in the comparison groups. The incidence of intra-uterine growth retardation was significantly higher in all the exposed groups than in the comparison groups. The incidences of congenital malformations were significantly higher in the exposed groups than in one or more of the comparison groups for the defects of the ears, eyes, jaws, brain, and tongue in all the exposed groups. Low set microtia, cataract or open eyelids, microcephaly or anencephaly, maxillary or mandibular hypoplasia, and protruding tongue were observed in all groups, but the numbers were significantly higher in the exposed groups compared with one or more of the comparison groups. Curled or missing tail and intra-auricular septal or intra-ventricular septal defects were observed in higher numbers in the groups in which both the males and the females were exposed than in the comparison groups. Male:female sex ratios were significantly higher in the groups in which males only and females only were exposed.

Unusual type of brachydactyly associated with intraventricular septal defect and deafness

We report a patient with brachydactyly associated with an intraventricular septal defect and sensorineural deafness. The second fingers had ulnar curvature. Radiographs showed bilateral hypoplastic middle phalanges of the 2nd and 5th fingers and the left 2nd digit showed hyperphalangy. The association of this unusual brachydactyly, intraventricular septal defect, and deafness does not conform to any known condition.

Anatomic and functional imaging of congenital heart disease with digital subtraction angiography.

Digital subtraction angiography (DSA) of the heart was performed in 54 patients for the evaluation of congenital heart disorders. DSA produced high-quality diagnostic images and accurate physiologic shunt data that compared favorably with catheter angiography and nuclear medicine studies. Retrospective analysis of this series of patients indicated that DSA studies contributed sufficient information to shorten significantly or modify cardiac catheterization in 85% (79/93) of the defects that were identified. Interatrial septal defects were particularly well diagnosed, with identification occurring in 10 of 10 cases, whereas intraventricular septal defects were identified in only 6 of 9 patients. Evaluation of postsurgical patients was accurate in 19 of 20 cases.

Abnormal development of the rat heart during prenatal hypoxic stress.

SummaryPregnant rats were subjected to high altitude hypoxic stress and the offspring studied for heart malformations. Of the 99 fetuses born from the stressed rats, 28 were shown to have defective hearts. The most common defects (69%) were septal, ranging from very small apertures to a large opening covering one-fourth of the interventricular septum. Of the septal defects the most common was a communication between the left ventricle and right atrium which entered the left ventricle just below the cusps of the aortic valve and the right atrium just above the tricuspid valve. There were also intraventricular septal defects and 1 intra-atrial. Other defects were 4 with 90° rotation of the ventricles, 1 aortic stenosis, 1 pulmonary atrial stenosis, 1 narrowed infundibulum, and 1 over-riding aorta. Of the control animals only 7.5% had heart deformities, all of which were small interventricular defects, except in 1 fetus where the septum secundum failed to form.

Hemodynamic findings before and after occurrence of a left ventricular-right atrial fistula

A patient who had a left ventricular-right atrial fistula, produced at heart surgery, is described. This occurred when the medial leaflet of the tricuspid valve was used in an attempt to close an intraventricular septal defect. A residual shunt remained, producing a fistula. Pressure changes occurred which were characterized by an elevated right atrial maximum and elevated mid-diastolic and end-diastolic right ventricular components. In the presence of left to right shunting at the atrial level, with these characteristic right atrial and right ventricular pressures, the diagnosis of left ventricular-right atrial fistula should be considered.

Inflammatory Pseudotumor of the Lung

The first case of an inflammatory pseudotumor of the lung recorded at the University of Missouri Medical Center, Columbia, Mo., affords the opportunity to introduce this entity into the radiological literature. This relatively rare condition should not be confused with the so-called “pseudotumor of the lung” which consists of fluid loculated between layers of pleura. Report of a Case An 8-year-old white girl was first seen at the University of Missouri Medical Center on June 30, 1959, for treatment of cardiac failure. An admission chest film showed a greatly enlarged heart and diffuse pulmonary edema (Fig. 1). The patient improved on medical therapy and at subsequent cardiac catheterization, a diagnosis of interventricular septal defect was made. On April 5, 1960, through a median sternotomy, under open heart technic with the heart-lung bypass, the intraventricular septal defect was closed. The patient did well, and roentgenograms obtained July 15, 1960, showed marked decrease in cardiac size and clearing...

Surgical repair of intraventricular septal defects: report of a case.

Evidence reveals that a high proportion of patients with intraventricular septal defects must lead lives of restricted activity and that others die prematurely. Intraventricular septal defects are commonly located high in the septum and connect the left ventricular chamber immediately proximal to the aortic valve to the right ventricular chamber in the region of the median leaflet of the tricuspid valve. Defects in this region may be associated with other defects, such as pulmonic or infundibular stenosis and overriding of the aorta. Less commonly intraventricular defects may be located lower in the muscular septum. They result from failure of the lower ventricular septum growing from the apex to meet and fuse with the downward growing aortic septum. This report deals with the surgical closure of intraventricular septal defects uncomplicated by other abnormalities. The greater pressure within the left ventricle causes a left to right shunt of blood during ventricular systole,
