Transaortic septal myectomy at the time of aortic valve replacement for severe aortic stenosis: a case series of 55 cases.

Introduction: Symptomatic aortic valve stenosis (AS) is associated with asymmetric basal septal hypertrophy (ABSH) in 10% of cases. In this cohort, it has been suggested that rectification of the left ventricular outflow tract obstruction (LVOTO) by concomitant septal myectomy (CSM) can improve the results of aortic valve replacement (AVR).

Objective: This study aims to present the technique of AVR with CSM for severe AS with ABSH and to determine the associated early and late post-operative outcomes.

Cor triatriatum dexter as an incidental finding due to symptomatic bicuspid aortic valve stenosis.

Cor triatriatum is a rare congenital heart defect in which a thin, fibro-muscular membrane divides the left or right atrium into two chambers resulting in a triatrial heart. Subdivision of the left atrium named cor triatriatum sinister (CTS), is the more common form, whereas the right atrial equivalent called cor triatriatum dexter (CTD) is rarer. They account for up to 0.

Acute obstruction of a mechanical aortic valve in a young woman: case report and review of the literature.

Unlabelled: Acute aortic valve obstruction is a medical and surgical emergency necessitating intensive care unit admission. The differential diagnosis includes thrombosis, pannus formation or vegetations. The diagnosis should be obtained as soon as possible, with possible orientation towards the cause.

Diffuse coronary artery disease and dystrophic calcification of the radial artery--is there an association?

Arterial revascularization is an attractive surgical option in the management of coronary artery disease (CAD). In the recent years, the radial artery (RA) has enjoyed resurgence in popularity as the preferred arterial conduit of choice after the internal mammary artery. Despite renewed interest in RA conduits, little is known of the prevalence of preexisting disease in this vessel, and in particular which patient subgroups are most affected, hence implications for long-term graft patency remain uncertain.

Repair of left coronary artery aneurysm, recurrent ascending aortic aneurysm, and mitral valve prolapse 19 years after Bentall's procedure in a patient with Marfan syndrome.

A 45-year-old female with Marfan syndrome had a Bentall's procedure performed 19 years ago. She presented with a 4-year history of gradually worsening dyspnea and decreasing exercise tolerance. Investigations revealed severe mitral valve prolapse, a left main stem coronary artery (LMSCA) aneurysm, and a recurrent aneurysm of the ascending aorta.

Off-pump coronary artery bypass grafting and left lower lobectomy simultaneously performed via a left postero-lateral thoracotomy.

A 75-year-old male with angina and a squamous carcinoma of the left lower lobe underwent a single-stage procedure for the treatment of these lesions. Through a left postero-lateral thoracotomy, a left lower lobectomy was performed with systematic nodal dissection including the subcarinal and paraaortic lymph nodes. A reversed saphenous vein segment was used to bypass the left anterior descending artery from the ascending aorta without cardiopulmonary bypass.

Utilizing a patent proximal vein graft stump in a case of coronary artery reoperation.

A patient was referred for coronary artery bypass reoperation. The right internal mammary artery (RIMA) was anastomosed to the left anterior descending artery (LAD) and a left radial artery graft (RA) was sequentially anastomosed to the posterior descending artery (PDA) and left ventricular branches (LVB) of the right coronary artery (RCA). The patent proximal stump of an occluded saphenous vein graft was used as an interposition segment to lengthen the RA graft, thereby avoiding the need for a further anastomosis on the ascending aorta.

Transpericardial extra-anatomic intrathoracic aortic bypass conduits in the management of coarctation of the aorta.

Two varied cases of coarctation of the aorta are described, in which transpericardial ascending to descending thoracic aortic conduits were routed around the right atrium, utilizing deep hypothermic circulatory arrest. The approach was through a median sternotomy in two patients. The first case is a 52-year-old female who underwent combined aortic valve replacement for aortic stenosis and repair of aortic coarctation distal to the left subclavian artery.

Simplified technique for determining the length of artificial chordae in mitral valve repair.

Artificial chordal replacement using polytetrafluoroethylene sutures has become an established component in the technique for mitral valve replacement with good long-term results. Although various techniques have been described to determine the length of the artificial chordae, this has remained somewhat problematic. A neo-chordae that is too short will, in effect, result in a restricted leaflet movement.

Spontaneous coronary artery dissection presenting as cardiac tamponade.

Spontaneous dissection of the left main coronary artery is the least common of all dissections involving the coronary arteries. It usually occurs in young women, especially in the peripartum or early postpartum period. We describe the case of a 59-year-old man with no previous history of atherosclerotic heart disease who presented in cardiac tamponade and was found to have a spontaneous left main stem coronary artery dissection at cardiac catheterization.
