Prediction of individual prosthesis size for valve-sparing aortic root reconstruction based on geometric features.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference
Valve-sparing aortic root reconstruction is an up- and-coming approach for patients suffering from aortic valve insufficiencies which promises to significantly reduce complications. However, the success of the treatment strongly depends on the challe...

Reliability of Percutaneous Pulmonary Vent and Coronary Sinus Cardioplegia in the Setting of Minimally Invasive Aortic Valve Replacement: A Single-Center Experience.

Journal of cardiothoracic and vascular anesthesia
OBJECTIVES: Evaluating the efficacy of 2 new percutaneous devices specifically designed to be placed through the right internal jugular vein, therefore named "necklines," for achieving retrograde cardioplegia and pulmonary venting in the setting of m...

Early surgery after angiography in patients scheduled for valve replacement.

Asian cardiovascular & thoracic annals
Background There are limited data regarding the risks of cardiac surgery early after coronary angiography in patients scheduled for isolated aortic and/or mitral valve replacement. Our aim was to evaluate the risk of early surgery after coronary angi...

Beating Heart Minimally Invasive Mitral Valve Surgery in Patients With Patent Coronary Bypass Grafts.

The Canadian journal of cardiology
BACKGROUND: Redo mitral valve surgery in patients with patent coronary bypass grafts carries a risk of graft injury and postoperative bleeding. We compare early results of reoperative minimally invasive on-pump beating heart mitral valve surgery (OPB...

Factor V Leiden and Cardiopulmonary Bypass.

The journal of extra-corporeal technology
We present a case of a patient with factor V Leiden with an antithrombin III activity of 67% who received a successful aortic valve replacement supported by cardiopulmonary bypass (CPB). A safe level of anticoagulation was achieved by monitoring acti...

Mitral Valve Surgery: Current Minimally Invasive and Transcatheter Options.

Methodist DeBakey cardiovascular journal
The mitral valve is a highly complex structure, the competency and function of which relies on the harmonious action of its component parts. Minimally invasive cardiac surgery (MICS) for mitral valve repair or replacement (MVR/r) has been performed s...

Robotic Mitral Valve Replacement in Pectus Excavatum.

Journal of cardiac surgery
Exposure of the mitral valve can be challenging using conventional sternotomy and thoracotomy incisions in patients with pectus deformity. We report the use of a robotic approach to replace a rheumatic mitral valve in a patient with pectus excavatum....

Robotic Transcatheter Mitral Valve Replacement Using the Sapien XT in the Setting of Severe Mitral Annular Calcification.

Journal of cardiac surgery
We describe the use of the Sapien XT, placed in the mitral position using a totally endoscopic robotic approach in a 76-year-old man with extensive circumferential mitral calcifications and severe stenosis. The patient was at high risk for traditiona...

Prevention of Unilateral Pulmonary Edema Complicating Robotic Mitral Valve Operations.

The Annals of thoracic surgery
BACKGROUND: Unilateral pulmonary edema (UPE) has been reported after mitral operations performed through the right side of the chest. The clinical presentation is compatible with an ischemia-reperfusion injury. This report describes modifications to ...
