ABSTRACT
PA-LA communication is a rare congenital heart disease consisting of direct communication between a branch of the PA and LA through an aneurysmal structure. This disease reveals the central cyanosis with clubbed fingers and surgical repair is needed when symptoms are apparent. Computed tomography is highly recommended for definitive diagnosis. Angiographic catheterization is also recommended to support the diagnosis and decide on the treatment. PA-LA communication is categorized into 4 types. Two types do not need cardiopulmonary bypass (CPB) when treated surgically, but the others need CPB. A 16-year-old girl with clubbed fingers was found to have PA-LA communication by 3DCT. She underwent surgery and was discharged in good condition. The surgical procedure was done through median sternotomy without CPB. The anomalous aneurysmal fistula was doubly ligated. No communication was found after ligation by TEE.
ABSTRACT
Essential thrombocythemia (ET) is an uncommon type of myeloproliferative disorder, characterized by both thrombotic and hemorrhagic diatheses. No clear guidelines exist for the pre- or post-operative management of patients with ET undergoing cardiac surgery. Here, we present a rare case of a patient with essential thrombocythemia and severe aortic stenosis, who needed an aortic valve replacement on cardiopulmonary bypass and who suffered no complications.
ABSTRACT
We described a patient with free wall rupture followed by papillary muscle rupture due to acute myocardial infarction. A 69-year-old man was transferred complaining of transient unconsciousness. His clinical history, electrocardiogram, and chest CT showed myocardial infarction with free wall rupture indicated that several days had passed since the onset. Coronary angiography showed occlusion of the right coronary artery and severe stenosis of the left anterior descending artery. Since cardiac rupture was at inferior wall and hemorrhage wasn't active, repair of the rupture using fibrin glue and fibrin sheet and coronary artery bypass grafting to the left anterior descending artery was performed without cardiopulmonary bypass. On the 10th postoperative day, his arterial oxygen saturation suddenly deteriorated. Transesophageal echocardiography revealed papillary muscle rupture and severe mitral regurgitation. Emergency mitral valve replacement was performed. After two emergency operations, he gradually recovered and were discharged to home. In three months after discharge, he was admitted again due to congestive heart failure with left ventricular aneurysm at inferior wall and recovered in response of conservative treatment. Surgical experience of double rupture is rare. Based on this case, it may be necessary to perform reperfusion therapy toward even this case of recent myocardial infarction, to prevent papillary muscle rupture. It also may be better to use a patch on free wall rupture to prevent cardiac aneurysm.
ABSTRACT
A 27-year-old woman was given a diagnosis of infectious endocarditis with severe tricuspid regurgitation. Despite adequate antibiotics therapy, her general condition did not improve, and moreover multiple pulmonary abscesses were detected by computed tomography. Therefore surgery was indicated. Surgery consisted of removal of vegetation and tricuspid valve plasty with autologous pericardial patch augmentation of the anterior leaflet. Tricuspid valve plasty was carried out without prosthetic materials. Her postoperative course was uneventful with only mild tricuspid regurgitation. One year after surgery, neither recurrence of infection nor worsening of tricuspid regurgitation was noted. This method could be a useful technique for young patients with severe infection.
ABSTRACT
A 47-year-old man had suffered from high grade fever and dyspnea for 10 days. He was transferred to our hospital in a condition of shock. Echocardiography showed severe diffuse hypokinesis of left ventricle (EF 21%), and multiple mobile thrombi in the left ventricle. Under a diagnosis of LV thrombi due to acute myocarditis, transatrial removal of LV thrombi was performed using video-assisted cardioscopy. He was weaned from cardiopulmonary bypass under IABP support. Postoperatively, he suffered from thromboembolism of the cerebral and right brachial artery. Thrombectomy of the right brachial artery and anticoagulation therapy was performed. IABP was removed on POD 3, and he no longer needed respiratory control on POD 4. Echocardiography on POD 6 showed marked improvement of the LV contraction (EF 52%). After rehabilitation, he was discharged on POD 23 on foot. Video-assisted cardioscopy allowed transatrial removal of LV thrombi, and preserved left ventricular function by avoiding ventriculotomy. Perioperative thromboembolism must be taken care of for a patient with multiple LV thrombi.
ABSTRACT
We demonstrated the clinical features and outcome of 87 children with idiopathic thrombocytopenic purpure (ITP). Most of them were younger children with severe thrombocytopenia; 71.3% were under 5 years old and 49.4% had platelet counts below 1×10<sup>4</sup>/μl. Initial treatment consisted of high-dose intravenous immunoglobulin in 60 (69.0%), steroid in 10 (11.5%), and no therapy in 17 (19.5%). More than 90% of the children with platelet counts below 2×10<sup>4</sup>/μl received treatment, but most children with platelet counts above 2×10<sup>4</sup>/μl were observed without treatment. No patients had complications with CNS hemorrhage. Chronic ITP was noted in 17 patients (19.5%). Their mean age was 6 years 3 months compared with 2 years 8 months for the acute patients (p<0.01). But there were no significant differences in sex, platelet count, and initial treatment between chronic ITP and acute ITP. Six (35.3%) out of 17 children with chronic ITP subsequently achieved a spontaneous recovery. As of today, only 3 patients (3% of all patients, and 17.6% of patients with chronic ITP) have platelet counts below 5×10<sup>4</sup>/μl. The overall prognosis and quality of life were excollent. <i>Helicobacter Pylori</i> (<i>H. pylori</i>) infection was found in 7.1% of the chronic patients and 5.3% of the acute patients, but platelet counts of them returned to normal without <i>H. pylori</i> eradication thrapy. It seemed that <i>H. pylodi</i> infection played a minor role in pediatric ITP.
ABSTRACT
This cross-sectional study examined cigarette smoking knowledge, attitudes, and practices among medical students in a southwestern region of China. The subjects included 557 and 223 first and fourth year Chinese medical students, respectively. Comparison data were collected from 74 Japanese and 90 Vietnamese fourth year medical students. The smoking rate among the fourth year medical students in China (7.0%) was significantly higher than among the first year medical students (2.8%), and higher than among the medical students from Vietnam, but lower than the medical students from Japan. The fourth year Chinese students had a more permissive attitude toward cigarette smoking by physicians compared with the first year students, and the lowest knowledge base on cigarette smoking-related diseases among the students from all three countries. Based on a multivariate analysis, the factors associated with cigarette smoking were male gender, having friends who smoked, and exhibiting a permissive attitude toward smoking. Implementations aimed at improving tobacco education and addressing the gender differences and peer influences related to cigarette smoking are needed to improve Chinese medical students’ knowledge and attitudes about cigarette smoking, and to prevent students from starting to smoke cigarettes.

Mycobacterial infection after open-heart surgery is a rare complication. We report 2 cases of cutaneous infection caused by <i>Mycobacterium fortuitum</i> (<i>M. fortuitum</i>). Case 1: A 56-year-old man had wound infection from the 10th postoperative day (POD). The growth of <i>M. fortuitum</i> was detected on the 38th POD. Combination of multiple antibiotic therapy was performed. He was cured after several recurrences of cutaneous ulcer and abscess following 15 months. Case 2: A 26-year-old man had wound infection from the 28th POD. Deep sternal infection with mediastinitis developed. Bacteriological examination revealed the growth of <i>M. fortuitum</i> on the 61st POD. Omentopexy was performed on the 67th POD. Wound infection completely healed, and the patient was discharged from our hospital on the 137th POD. Mycobacterial infection should be considered when the wound infection is resistant to ordina antibiotics.
ABSTRACT
We report 4 cases of valvular injury following nonpenetrating cardiac trauma in 3 men and 1 woman ranging in age from 24 to 72 years. In all cases the cause of trauma was blunt chest trauma. One patient was operated in 4h, but the other 3 patients were operated on more than 6 months after the accidents. Lacerated aortic cusp was observed in 2 patients, ruptured anterior papillary muscle of mitral valve, and ruptured chordae tendinae of the tricuspid vale were observed in 1 patient each respectively. Three patients underwent valve replacement (2 aortic and 1 mitral valves), and another patient underwent chordoplasty in the tricuspid valve. Their post-operative courses were uneventful. Careful observation, such as echocardiography, were required following the blunt chest trauma.
