[Surgical left ventricular remodelling via endoventriculoplasty: clinical observation].

A case of dilated ischemic cardiomyopathy, with severely impaired left ventricular systolic function, treated by endoventriculoplasty and CABG, is reported. The authors discuss the modern concepts regarding the surgical treatment of large anterior asynergic scars following occlusion of the LAD. Since there are more similarities between akinesia and dyskinesia than previously thought, the endoventriculoplasty of DOR may constitute a new way to surgically remodel the left ventricle in dilated cardiomyopathies with large anterior akinesia. This surgery significantly improves the ventricular function and the overall patients' prognosis at short and mid term follow up.

[Intrapulmonary lung sequestration: a case report].

Through the presentation of a classical case of intrapulmonary pulmonary sequestration, the nosology of congenital lung malformations is reviewed. The histology, imaging, and surgical treatment of this congenital anomaly are briefly discussed.

Spontaneous tracheal rupture: a case report.

We report the case of a spontaneous posterior tracheal wall rupture following a cough. A 67-year-old woman with a history of longstanding treatment with corticosteroids (8 years) for Giant Cell Arteritis had general anesthesia for cataract removal. Surgery and anesthesia were uneventful. In the recovery room, the patient coughed and soon after developed subcutaneous emphysema of the neck. Chest radiography confirmed the clinical diagnosis of marked subcutaneous emphysema and showed huge pneumomediastinum and minor right pneumothorax. A thoracic CT scan revealed a large laceration of the posterior tracheal wall (a 4 cm longitudinal tear), extending from the middle of the trachea to the level of the carina. Surgical repair consisted in closure of the dilaceration using an autologous pericardial patch. It seems reasonable to suspect the facilitating role of connective tissue fragility due to chronic corticosteroid administration in the development of this tracheal rupture following cough. Tracheal rupture is a potentially lethal injury, which can be repaired successfully if the diagnosis is made early. Risk factors, diagnosis and principles of treatment of this lesion are discussed.

[The different accesses to the left atrium].

The knowledge of the anatomy of the atria and interatrial septum permits different routes to approach the left atrioventricular valve. The Waterston's or Sondegaard's groove approach is the most frequently used, but other approaches such as Dubost'transseptal technique, vertical transseptal approach (Berreklouw-Guiraudon), biatrial inferior transseptal approach (Couëtil) or Saksena's approach may be relevant in special situations. It is the purpose of this article to review the anatomic and technical basis of these different approaches and their respective merits.

[Left ventricular aneurysms: principles of surgical treatment].

After reviewing the historical background, the morphology and physiopathology of left ventricular aneurysms, the authors review the physiology, the technical aspects, and the current surgical indications of aneurysmectomy, with a particular emphasis on the concept of endoventriculoplasty of Jatène & Dor.

[Secondary prevention of coronary events by coronary artery bypass surgery].

Coronary artery bypass surgery has shown its superiority on other therapeutic options in specific but frequent indications such as left main lesions, multivessel disease with alteration of ventricular function, proximal lesions of the LAD, and multivessel diseases in diabetic patients. After reviewing the epidemiology of coronary artherosclerosis, we emphasize the efficacy of the surgical treatment compared to medical or interventional therapy for preventing ischemic events. The results derived from randomized studies may be even further improved by the implementation of beating heart surgery and the systematic use of multiple arterial conduits.

[Clinical case of the month. Management of thoracic empyema].

Adequate management of thoracic empyema implies prompt diagnosis, the application of simple treatment algorithm, and the avoidance of the complications of the chronic stage. A case report of a typical case of thoracic empyema is an opportunity to review the management of this affection.

[Homograft mitral valve replacement].

The total homograft replacement of the left AV valve and subvalvular apparatus constitutes a delicate operation, which may prove beneficial in young patients with extensive bacterial endocarditis. The case of a staphylococcal endocarditis in a young drug addicted patient, operated three years previously of mitral valve repair for the same pathology, is presented. In addition to the complete excision of infected tissues and valvular substitution with biological material, this technique has the advantage of avoiding long term anticoagulation. The history, technical key points, and current indications of mitral homograft in the surgery of the left atrio-ventricular valves are reviewed.

[Clinical case of the month. Type A aortic dissection after valve replacement].

The risk for aortic dissection or further dilation of the ascending aorta exists after aortic valve replacement. We present a case of acute aortic dissection following replacement of the aortic valve. The management and treatment of dilated ascending aorta associated with aortic valve disease are reviewed and discussed.

Double orifice right atrioventricular valve in atrioventricular septal defect: morphology and extension of the concept of fusion of leaflets.

A rare observation of a double orifice right atrioventricular valve in a partial form of atrioventricular septal defect is reported. The concept of leaflet fusion along part of their anticipated zones of apposition is used to explain the formation of this anomaly. We show that this concept can account for the different morphologic presentations of atrioventricular septal defect.
