Radical sternectomy for osteomyelitis without reconstruction post-coronary artery bypass graft: 10 years on.

Radical sternectomy with sternal reconstruction using synthetic mesh or titanium plates has been described before with excellent results. However, radical removal of the sternum without reconstruction is a rare surgical treatment for complicated deep sternal wound infections (DSWI). The long-term outcome following this radical operation is not well-known due to the limited number of cases in the literature. We report on a patient 10 years after a radical sternectomy for DSWI who presented with shortness of breath. We highlight some of the anatomical and physiological changes the chest cavity may undergo and the fact that this patient had a near normal quality of life in the 10 years following the sternectomy.

Infected Takayasu's arteritis presenting with aortic perforation.

We want to remind Physicians that unusual conditions can present in unusual ways and to keep an open mind always.

Left ventricular outflow tract cyst: What was it and where did it go?

Cyst or thrombus formation in the left ventricular outflow tract of a normal heart is very rare. We present a case of a male who presented with a major stroke and was found to have a freely mobile cystic mass in the left ventricular outflow tract, with an otherwise completely normal heart. He had some risks factors for hypercoagulability (reduced protein C activity and raised fibrinogen), but only received aspirin therapy due to his stroke severity (haemorrhagic transformation). Once his brain imaging suggested it was safe to proceed, repeat imaging showed the mass had gone, so cardiac surgery was avoided. What was it and where did it go?

Right aortic arch with mirror image branching found incidentally during coronary surgery.

Right aortic arch with a left innominate (brachiocephalic) artery with mirror image branching (RAMI) is a rare congenital anomaly, and it is unusual to diagnose it in adulthood. There are very few cases of cardiac surgery being performed for acquired cardiac disease on a congenital RAMI patient. We present a patient who had an incidental finding of a RAMI anomaly found during coronary artery bypass surgery. Post-operatively computerised tomography showed both his congenital lesions and his bypass grafts.

A tale of three pumps and a mechanical heart.

Temporary mechanical circulatory support device (tMCS) failure could qualify patients with advanced heart failure to receive a long-term solution. We report on a patient who presented with cardiorespiratory arrest that required a tMCS and developed acute type A aortic dissection. Data Sources: our case adds further evidence regarding the support of a patient with a second (or more) incidence of tMCS. This patient subsequently underwent left ventricular assist device insertion and type A aortic dissection repair, as a combined procedure, with a satisfactory outcome.

Coronary artery anomalies: Unusually high incidence of anomalies with a malignant course in an Asian population.

OBJECTIVES: Coronary artery anomalies are uncommon, but important cardiac malformations, representing the second commonest cause of death in young athletes. METHODS: We utilized computerized tomographic angiography to screen and precisely delineate coronary artery anomalies in patients with minimal cardiac symptoms. RESULTS: During 3.5-year period, we performed 2888 computerized tomographic angiographies. A total of 33 (1.1%; 95% confidence interval = 0.7-1.5) cases of coronary artery anomalies were identified (mean age = 44 ± 13.5 (15-70) years). In total, 23 patients (mean age = 43 years) had malignant coronary artery anomalies with an inter-arterial course of the aberrant vessel: of which 3 had left main coronary artery arising from right coronary sinus and 20 right coronary artery from left sinus; 19 patients were of Asian and 14 were of Arab origins. Of interest, 21 out of 33 patients had chest pain, 5 had palpitations, and 2 had breathlessness. There were no examples of sudden cardiac death. All patients received appropriate advice regarding physical exertion and medical management, and remained well for 2-5 years of follow-up. Of 33 patients, 4 had significant symptomatic coronary artery disease requiring intervention: 1 percutaneous coronary intervention and 3 coronary artery bypass graft surgery. CONCLUSION: There is a relatively high incidence of coronary artery anomalies with malignant course in Asians. The vast majority were managed conservatively.
