Abstract

None:

A patient with complicated Stanford type B aortic dissection and a large ulcer-like projection just distal to the left subclavian artery (LSA) underwent thoracic endovascular aortic repair (TEVAR) using a physician-made 1-cm fenestration and L-shaped marker. This technique allowed accurate alignment with the LSA under fluoroscopic guidance without additional devices. Postoperative and 6-month follow-up computed tomography confirmed good outcomes. This simplified, economical Zone 2.5 TEVAR approach may be a viable treatment option for high-risk patients with anatomically challenging aortic dissections.

Aortic Regurgitation III: Medical Management

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Mitral Stenosis III: Medical Management

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...
