Transcatheter aortic valve replacement is an increasingly common treatment of critical aortic stenosis. Many aortic stenosis patients have concomitant left ventricular dysfunction, which can instigate the formation of thrombus resistant to anticoagulation. Recent trials evaluating transcatheter aortic valve replacement have excluded patients with left ventricular thrombus. We present a case in which an 86-year-old man with known left ventricular thrombus underwent successful transcatheter aortic valve replacement under cerebral protection.

Case Reports
Repair of a large main pulmonary artery aneurysm in a 71-year-old Jehovah's Witness patient.
Pulmonary artery aneurysm is a rarely reported and poorly studied entity; most mentions in the literature are in case series and case reports. Cardiac surgery in Jehovah's Witness patients is occurring more frequently because of improved techniques of blood conservation. ⋯ The patient recovered rapidly, and her symptoms were greatly improved. We think that a patient's status as a Jehovah's Witness need not preclude potentially life-saving cardiac operations.

Case Reports
Inverted Takotsubo cardiomyopathy and the fundamental diagnostic role of echocardiography.
Takotsubo cardiomyopathy is characterized by the development of transient focal wall-motion abnormalities that involve the apical and midventricular segments, in the absence of obstructive coronary artery disease. A variant, inverted takotsubo cardiomyopathy, was described in 2010. We report 3 cases in which each patient's transthoracic echocardiogram revealed the characteristic basal and midventricular segmental akinesis of this variant. This pattern is not associated with coronary artery distribution, and it therefore can be differentiated from coronary artery disease with the use of echocardiography, by evaluating the distribution and temporal changes of akinetic areas.

Tracheobronchial-angle tumors involve the right main bronchus, the right upper lobar bronchus, and the lateral wall of the lower trachea. Resecting these tumors is one of the most complex procedures in thoracic surgery. In cases of high-caliber mismatch, the selection of a suitable anastomotic technique can be challenging. ⋯ We conclude that our one-stoma carinoplasty technique enables the resection of tumors at the right tracheobronchial angle, with acceptable morbidity and mortality rates. This method saves the unaffected part of the ipsilateral lung and can overcome high-caliber mismatch. Because of these and other advantages, we suggest that using our method first might preclude having to perform a right carinal sleeve pneumonectomy or using Barclay's method.

Aortic false aneurysm is a rare complication after cardiac surgery. In recent years, improved results have been reported in regard to the surgical management of these high-risk lesions. We retrospectively examined 28 consecutive cases (in 27 patients) of postsurgical aortic false aneurysm diagnosed at our institution from May 1999 through December 2011. ⋯ Aortic false aneurysm can develop silently. Surgical procedures should be proposed even to asymptomatic patients because of the unpredictable evolution of the condition. Radical aortic-graft replacement should be chosen rather than simple repair, because recurrent false aneurysm is possible.
