Transcatheter aortic valve implantation has been shown to be an effective treatment for severe aortic stenosis in high-risk surgical patients. Many of these patients have significant coexisting coronary artery disease. We report the first case of combined off-pump transapical aortic valve implantation and minimally invasive direct coronary artery bypass via a left mini-thoracotomy in an 82-year-old man with significant comorbidities. This combined procedure is technically feasible and can be performed safely in selected patients with aortic stenosis and left anterior descending artery lesion that is not suitable for percutaneous intervention.

A 55-year-old woman underwent elective mitral valve replacement due to severe rheumatic mitral valve stenosis. After valve replacement with a mechanical prosthesis, the patient failed to wean from the cardiopulmonary bypass. ⋯ Peripheral emboli are a known complication in patients undergoing mitral valve surgery for rheumatic mitral stenosis. In this report, we describe the case of a patient who sustained an intraoperative coronary embolus during a mitral valve replacement for rheumatic mitral stenosis.

A 60-year-old female presented with a two-year history of exertional chest pain and progressive dyspnea. Resection of a cardiac hemangioma arising from the area of the bifurcation of the left anterior descending and circumflex coronary arteries resulted in complete resolution of her symptoms. The symptoms were likely caused by coronary steal.

Damus-Kaye-Stansel biventricular repair for transposition of the great arteries with pulmonary hypertension.
An 18-year-old female with transposition of great arteries and severe pulmonary hypertension was successfully treated with Damus-Kaye-Stansel biventricular repair. Results of the 12-year follow-up showed satisfactory hemodynamics with the aortic valve staying closed throughout the cardiac cycle and without the pulmonary valve regurgitation.
