Case ReportsPseudoaneurysm fistulized into pulmonary artery 13 years after aortic surgery.
Pseudoaneurysm formation some years after aortic root or ascending aorta surgery, complicated by fistula formation through a branch of the pulmonary artery, is a rare condition described only in case reports. We describe a case of this rare complication in a 58-year-old man, which occurred 13 years after aortic surgery and was characterized by a huge pseudoaneurysm of 70 mm that fistulized into the right pulmonary artery, causing a life-threatening situation.

Background Reoperations are technically more difficult because of the risks associated with reentry in a heart with more advanced pathology, little reserve, and more frequent comorbidities. Routine peripheral cannulation before resternotomy is inadvisable, time-consuming, and has no noticeable role in decreasing the risks of reentry. We present our experience of resternotomy without routine peripheral cannulation. ⋯ We had 3 right ventricular, one right atrial, one pulmonary artery, and 2 inferior vena caval tears during resternotomy and dissection; bleeding was controlled easily without peripheral cannulation. Femoral cannulation before resternotomy was performed in one patient who needed an emergency pulmonary embolectomy. Conclusions Based on our experience, resternotomy with central cannulation is a safe strategy, and peripheral cannulation before resternotomy should be reserved for highly selected patients.

Case ReportsMitral regurgitation following pericardiectomy for constrictive pericarditis.
Pericardiectomy is the only definitive treatment option for patients with constrictive pericarditis. We present the case of a 67-year-old man who developed new moderate to severe mitral regurgitation following phrenic nerve-to-phrenic nerve pericardiectomy for constrictive pericarditis. The severity of the regurgitation was followed up by serial echocardiography which showed improvement 19 days later and complete resolution at 9 months after surgery. Potential mechanisms explaining the evolution of this mitral valve dysfunction in the setting of pericardiectomy are postulated.

Freestyle stentless bioprosthesis for aortic valve therapy: 17-year clinical results.
Aortic valve replacement with stentless bioprostheses has been shown to produce lower aortic gradients than stented bioprostheses, thus facilitating left ventricular mass regression and preventing heart failure. We sought to determine the long-term results of stentless biological aortic valve replacement over a 17-year follow-up. ⋯ Long-term results after aortic valve replacement with stentless biological prostheses compare favorably with those obtained with stented bioprostheses.

Case ReportsEndovascular repair for abdominal aortic aneurysm followed by type B dissection.
An 86-year-old man with an abdominal aortic aneurysm was diagnosed with type B aortic dissection accompanied by a patent false lumen that started at the distal arch of the thoracic aorta and terminated at the left common iliac artery. Meticulous preoperative assessment detected 3 large intimal tears in the descending aorta, abdominal aortic aneurysm, and left common iliac artery. We performed single-stage thoracic and abdominal endovascular aneurysm repair and concomitant axillary-axillary bypass. The abdominal aortic aneurysm with type B aortic dissection was successfully treated using a single-stage endovascular stent graft, without any complications due to the careful preoperative examinations.
