We experienced a case in which a 7-year-old boy with a characteristic elfin face, heart murmur, and mental retardation, underwent extended patch aortoplasty using diamond shaped dacron patch for congenital supravalvular aortic stenosis. The aortography performed before operation demonstrated diffuse stenosis just above the aortic valve, which was a typical hourglass type. The preoperative peak systolic pressure gradient between the left ventricle and ascending aorta was 86 mmHg, and was improved postoperatively. In this procedure no cusp was incised, resulting in no deformity of the aortic valve and no obstruction of coronary arteries. In conclusion this method was excellent for the diffuse type of supravalvular aortic stenosis.

The combination atrial septal defect and chronic constrictive pericarditis is very rare and poses diagnostic challenges because one tends to mask the clinical features of the other. We report such a case in which the initial diagnosis was suspected to be chronic constrictive pericarditis. This diagnosis was later changed to secundum atrial septal defect after transthoracic echocardiography. The complete diagnosis was made intra-operatively and the patient was relieved of both pathologies surgically.

Introduction and Aim: Patients who are going to receive prosthetic heart valve operation should have all indicated dental treatment performed before the valve is placed since they are more susceptible to infective endocarditis or to prosthetic valvular endocarditis arising from oral infections. The aim of this study is to evaluate the incidence of potential odontogenic infections sources in patients with preand postprosthetic heart valve operations. Materials and Methods: Twenty patients with preand postoperative valves replacement were subjected to comprehensive clinical and radiographic dental examination. Information considering age, gender, oral pathological features like periapical periodontitis, cysts, remained roots, impacted teeth, the existence of current diabetes mellitus and the form of the valve replacement were also included in the documentation. Results: Patients who were examined after prosthetic heart valve operation showed relatively more dental problems, more past canal treatments and more chronic periodontitis than patients who were examined before prosthetic heart valve replacement. Conclusion: Optimized dental treatment planning for patients scheduled to undergo cardiac valve replacement is always a need. Optimal cooperation between the cardiologist and the dentist is to be considered. The need of prophylactic antibiotics before and after several dental manipulations should be always discussed.

Introduction: Penetrating carotid artery injuries are very uncommon in civilian life and such patients rarely usually succumb to injuries before reaching the healthcare facility. This study was undertaken to bring forth the experience in management of this injury over the last 17 years in a tertiary care health facility in Indian side of Kashmir.Methods and Materials: All the patients who were managed for penetrating injuries from Jan 1990 to Dec 2007 were studied retrospectively. Results: Over the period of 17 years, the total of 37 patients was managed. Restoration of vascular continuity was attempted in all but one patient and 34 patients (92%) survived. 84% of patients with neurodeficit showed improvement or complete recovery. Conclusion: In cases of penetrating carotid injuries, strict adherence to Advanced Trauma Life Support ATLS) protocol followed by earliest restoration of vascular continuity can prevent sure mortalities and improve the neurodeficits.

The laser Doppler skin perfusion pressure (SPP) testing is expected to be beneficial for assessment of lower extremity peripheral artery disease (PAD) in patients on hemodialysis (HD). However, it is inconsistent at what timing SPP should be measured in relation to HD procedure. We measured each SPP value before, during, and after HD in 12 limbs of 6 patients without diabetes or PAD. There were not significant differences among mean SPP values, which were 90mmHg (SD=15), 83mmHg (SD=10), 89mmHg (SD=12), and 86mmHg (SD=16) at predialysis, 2-hr, 3-hr, and postdialysis, respectively. Results of this study suggest that compensatory responses to volume loss could contribute to maintain cutaneous perfusion during ultrafiltration of fluid. The laser Doppler SPP examination is likely to be useful even during or after HD. However, it seems that the SPP evaluation during or after HD requires carefulness.

The study was carried to establish hypertension as the major cause of heart failure in patients seen at the medicine directorate of a teaching hospital in Kumasi. The study also determined the efficiency of the pharmacotherapeutical management of hypertension in these patients. It was retrospective covering a 3-year period i.e. 2004 to 2006. It involved 307 heart failure patients consisting of 54.7% males and 45.3 females aged between 13 to 100 years with the age range of 53-60 years forming the majority. The median age of the patients was 54.6 years with a standard deviation of 18.12. The study was non-randomized and hence all heart failure patients who fell within these periods were used. Hypertension was found to be main cause of heart failure affecting 61.7% (n=189) out of the 307 patients who were admitted for heart failure. The patients had a mean systolic blood pressure of 148.2mmHg (SD.38.49) with the majority (28.7%) having systolic blood pressure in the range of 140-165mmHg. Their mean diastolic blood pressure was 92.60mmHg (SD. 22.32) with the majority (52.4%) having diastolic blood pressure in the range of 90-110mmHg. For asymptomatic heart failure patients with hypertension a thiazide diuretic was found be effective especially for elderly patients over 65 years. 23.8% of the patients in this study received the calcium-channel blocker, nifedipine to treat hypertension in heart failure, however, the newer calcium antagonists, felodipine and amlodipine were more effective in treating arterial hypertension in heart failure. 13.3% of the patients in this study received the β-blocker, carvedilol. Maximizing the dose of β-blockers and ACE-inhibitors, which extend survival in heart failure, was found be more effective than adding calcium-channel blockers to control hypertension. 41.7% of the patients in the study received low dose of the ACE-inhibitor, lisinopril (2.5mg-5mg) to treat symptomatic heart failure due to systolic left ventricular dysfunction, however, maximizing the dosage to 10mg-20mg was found to achieve a decrease in blood pressure as well as improved survival of the patients. The centrally acting drug, methyldopa was administered to 18% of the patients. A dosage of 250-1000 twice daily was found to effectively control their blood pressure. Although most of the patients were discharged with a decreased blood pressure levels the recommended target blood pressure levels of <140/90 or 130/80mmHg could not be achieved. This was due to the fact that most of the patients became asymptomatic and therefore were discharged to be reviewed at the cardiac clinic.

Sudden death in eating disordered patients has been attributed to cardiac arrhythmias and susceptibility might be identified by using heart rate variability (HRV) as a marker of impaired cardiac autonomic regulation. The aim of the study was to examine this parameter in female eating disorder patients and the effect of a short rehabilitation programme. HRV was investigated by linear and nonlinear analysis of ECG recordings from hospitalised female patients with diverse eating disorders. Twenty minute ECG recordings were made at admission, one week and six weeks later. HRV was significantly lower and of reduced complexity across eating disorder groups compared to control. Autonomic dysregulation was shown and differences between the groups persisted after six weeks of specialised hospital treatment. Heart rate variability can be measured simply and has potential as a marker of cardiac risk and an indication for high level care across the spectrum of eating disorders. Work was carried out at the Northside Clinic Eating Disorders Program, Greenwich, Australia.

An oxygenator failure during cardiopulmonary bypass is an emergency. The entire cardiac surgical team requires a comprehensive and methodical approach to troubleshoot the possible cause. We report that the bolus administration of methylene blue during cardiopulmonary bypass will induce a syndrome that mimics an oxygenator failure. Methylene blue has physical properties that cause venous saturation monitors to function inaccurately and the post oxygenator blood in the cardiopulmonary bypass circuit to appear deoxygenated. However, these events are temporary and do not require an emergent oxygenator change out. All members of the cardiac surgical team need to be aware of the effect of methylene blue administration during cardiopulmonary bypass and integrate this into their oxygenator failure troubleshooting algorithm.
