Endovascular repair of a right-sided thoracic aortic aneurysm with Kommerell diverticulum and aberrant left subclavian artery.

Background: A case of successful total endovascular repair of a right-sided descending thoracic aorta aneurysm (r-DTAA) with Kommerell diverticulum and aberrant left subclavian artery (ALSA) was reported. Few cases of this very rare pathology were reported, mostly describing a hybrid treatment, with only 2 cases of total endovascular repair performed to date.

Methods And Results: Our strategy consisted of endovascular ALSA occlusion, without preventive revascularization, and r-DTAA exclusion by 2 endoprosthesis implanted in a telescopic fashion, first the distal one, to achieve a relative straightening of the arch and support the proximal endoprosthesis, and then the proximal one, close to the right subclavian origin.

Left heart pump-assisted myocardial revascularization favorably affects neutrophil apoptosis.

Objectives: Granulocyte apoptosis is a key control process in the clearance of neutrophils from inflammatory sites, and its rate is modulated by a number of inflammatory mediators. In this study, we investigated whether the use of left ventricular-assisted technique (LVA) in beating heart myocardial revascularization would exert less impact on neutrophil apoptosis compared with conventional cardiopulmonary bypass (CPB).

Methods: Forty consecutive patients who underwent myocardial revascularization were randomly assigned to LVA (group A, 21 patients) or CPB (group B, 19 patients).

Mitral valve replacement and limited myectomy for hypertrophic obstructive cardiomyopathy: a 25-year follow-up.

Hypertrophic obstructive cardiomyopathy is a dynamic obstruction of the left ventricular outflow tract caused by septal hypertrophy and systolic anterior motion of the mitral valve. When the condition cannot be controlled by medical therapy the most frequently used surgical approach is left ventricular myotomy-myectomy. Mitral valve replacement (to correct another mechanism of obstruction) is another surgical option; however, its use for this condition is controversial.
