Off-pump axillo-coronary artery bypass: a simple approach for high-risk myocardial revascularization.

We report the case of a 66-year-old male with increasing angina occurring after two previous coronary artery surgery procedures. The second operation had been complicated by severe mediastinitis necessitating surgical drainage, and sternal stabilization. Angiography revealed an occlusion of the LAD bypass with a patent LAD associated with a stenotic circumflex coronary artery. The ascending aorta was severely calcified. An off-pump axillo-LAD coronary artery bypass was safely performed in conjunction with stenting of the circumflex artery. This approach dramatically simplified the procedure and reduced the operative risk. At the 52-month follow-up, the patient is free of any angina symptoms.

Recurrent Biatrial Myxomas in Carney Complex with a Spinal Melanotic Schwannoma: Advocacy for a Rigorous Multidisciplinary Follow-Up.

A 31-year-old female patient with a previous history of Carney complex and surgical resection for cardiac myxoma and bilateral adrenalectomy at 18 years old and 10 and 11 years old, respectively, was referred to our department with a diagnosis of recurrent biatrial myxomas incidentally discovered on echography. A magnetic resonance imaging (MRI) confirmed the diagnosis of a tumor protruding into the left ventricle, and the patient underwent a surgical resection of a large left atrial mass and a right-sided atrial small tumor. Diagnosis of bilateral atrial myxomas was confirmed by histologic studies. Postoperative outcome was uneventful, and the patient was discharged at the 7th postoperative day. Few months later, she reported trivial clinical symptoms suspecting a cervical radiculopathy. MRI confirmed the presence of a compressive cervical spinal cord tumoral mass at the C2-3 level leading to perform a surgical exeresis of the tumor. Histology showed a spinal melanotic schwannoma. This case highlights the risk of unexpected ubiquitary tumor locations and the importance of a rigorous transversal multidisciplinary follow-up to prevent severe complications in patients with Carney complex.

Surgical options for beating-heart aortic valve replacement in patients with patent coronary artery bypass.

BACKGROUND AND AIM OF THE STUDY: The study aim was to assess the surgical options and advantages of beating-heart aortic valve replacement (AVR) in patients with patent coronary artery bypasses. METHODS: In this prospective study, conducted between January and August 2006, four consecutive patients (mean age 77.5 +/- 6.6 years) each with patent coronary artery bypasses, underwent beating-heart AVR using two specific methods of myocardial perfusion based on the origin and status of the grafts, as assessed by preoperative angiography. Pre-operatively, all patients were in NYHA functional class III, and each received an aortic valve bioprosthesis. RESULTS: There were no hospital deaths. The mean duration of ICU stay was 3.2 +/- 1.3 days. One patient presented with transitory atrial fibrillation. At discharge, echocardiography confirmed normally functioning bioprostheses, with no significant transprosthetic gradient. CONCLUSION: Beating-heart AVR with patent coronary artery bypasses using continuous myocardial perfusion is a reliable, simple and effective technique to reduce the risks of graft and myocardial injuries, and to achieve optimal preservation of the hypertrophic myocardium with coronary artery disease.

Incidental disclosure of asymptomatic coronary embolic occlusion related to mitral valve papillary fibroelastoma: an unusual finding and a review of the literature.

Cardiac papillary fibroelastoma (CPF) located on mitral and aortic valves are known to produce systemic embolism mainly represented by strokes, whereas myocardial infarction and sudden death usually result from specific locations around LVOT. Coronary artery embolic occlusion originating from a mitral location has not yet been reported. The case is reported of a 42-year-old man referred for surgical treatment of a mitral valve papillary fibroelastoma disclosed after transitory and completely regressive left hemicorporeal deficiency and previous myocardial infarct. Due to the left chamber location, surgery was scheduled and complete removal of the mass achieved. These findings emphasize the potential life-threatening complications of CPF and, independent of risk factors, the need to perform systematic coronary angiography before surgical excision is considered.

Off-pump myocardial revascularization in a diabetic patient with severe hemophilia B and impaired left ventricular function: hematological and operative strategies.

Coronary surgery with diabetes and severe hemophilia B is a challenging situation requiring specific and adequate therapeutic considerations. We herein report the case of a 52-year-old diabetic patient with severe factor IX deficiency and impaired ventricular function, who was scheduled for myocardial revascularization because of exertional angina and recurrent myocardial infarctions following infusions of factor IX concentrate. The patient underwent a successful off-pump direct myocardial revascularization with neither hemorrhagic nor thrombotic complications. Hematological protocols and operative strategies are assessed and discussed.

Beating-heart approach and moderately delayed surgical management of postinfarction ventricular septal rupture: an advisable approach to improve results?

Early repair of postinfarction ventricular septal rupture is usually associated with significant mortality and morbidity. Assessing conditions to moderately delay the surgical intervention and reduce cardioplegic arrest may be an interesting approach to improve hospital results. Results of five non-selected patients in whom surgery was moderately delayed and performed according a policy of reducing the cardioplegic-induced ischemia were reviewed. Surgical options are discussed as well as observed advantages.
