Effect of PEEP on left ventricular function in right-heart-bypassed dogs

Journal of Applied Physiology, 1981
Positive-pressure ventilation with positive end-expiratory pressure (PEEP) has been associated with elevation of left ventricular filling pressure for a stable or reduced cardiac output. To exclude the possibility that right ventricular distension due to increased pulmonary vascular resistance decreases left ventricular compliance (ventricular ...

Total extracardiac right heart bypass.

Circulation, 1992
Total cavopulmonary connection has been proposed as a rational alternative to atriopulmonary connection for complex Fontan operations. In addition to fluid dynamic advantages proposed by de Leval, total right heart bypass may address an emerging important issue after repair of single ventricle: late atrial arrhythmias.

Reoperation of Coronary Artery Bypass with Right Gastroepiploic Artery on a Beating Heart

The Thoracic and Cardiovascular Surgeon, 1997
The case of a 67-year-old male with double-vessel coronary artery disease combined with a severely calcified ascending aorta, moderate aortic insufficiency, cholecystic stones, and unruptured intracranial aneurysm is presented. Successful coronary artery bypass reoperation is described using the right gastroepiploic artery through an additional left ...

Right Heart Bypass for Inferior Vena Cava Tumor Thrombus Extending into Heart

Asian Cardiovascular and Thoracic Annals, 1999
Radical nephrectomy with en bloc inferior vena caval tumor thrombectomy improves survival in patients with renal cell carcinoma with a tumor thrombus extending into the inferior vena cava. Cardiopulmonary bypass with or without deep-hypothermic circulatory arrest is advocated when the tumor thrombus extends into the right heart chambers.

Computer aided design of right heart bypass (Fontan) operations

Proceedings of the First Joint BMES/EMBS Conference. 1999 IEEE Engineering in Medicine and Biology 21st Annual Conference and the 1999 Annual Fall Meeting of the Biomedical Engineering Society (Cat. No.99CH37015), 2003
Each year 8 out of 1000 babies are born with congenital defects of the right heart. Right heart bypasses, known as "Modified Fontans", are the most common methods used to establish a viable pulmonary circulation in the infant. Fontan has become a generic term applied to numerous surgical procedures that separate the systemic and pulmonary circuits in ...

Right Heart Assist during Beating Bypass for Severe Left Ventricular Dysfunction

Asian Cardiovascular and Thoracic Annals, 2002
Three patients with triple-vessel disease and severe left ventricular dysfunction underwent successful revascularization on a beating heart, using a right ventricular assist system. Heparin-coated circuits with a centrifugal pump provided 2.5 to 3.5 L·min −1 of flow to maintain good ...

[Experience of coronary artery bypass grafting on the beating heart with right heart bypass; 3 cases of octogenarian].

Kyobu geka. The Japanese journal of thoracic surgery, 2002
Right heart bypass (RHB) yields more stable hemodynamics by increasing left ventricular preload and collapse right ventricular chamber during the displacement of the heart on beating heart coronary artery bypass grafting (CABG). Recently beating heart CABG gaining popularity, and the indications for CABG have increasingly expanded to elderly person ...

The Effects of Right Heart Bypass on Acute Ventricular Failure with and without Ventricular Fibrillation

Chest, 1972
A technique was developed for closed-chest bypass of the right ventricle. Blood is removed from the right atrium and returned into the pulmonary artery. The blood return cannula can be inserted without x-ray equipment. The maximum flow through the system is ten liters per minute.

Effects of left heart bypass on right ventricular function.

Transactions - American Society for Artificial Internal Organs, 1983
Right ventricular function has been studied in a canine ejecting heart model in-situ with intact sympathetic innervation and constant cardiac output, during varying degrees of left heart bypass ratio ranging from nil to total left ventricular decompression.

The history of right heart bypass before Fontan.

Herz, 1992
Numerous clinical and experimental studies have suggested that adequate pulmonary blood flow and normal central venous pressure may be maintained without significant contribution of right ventricular function. These data induced experimental and clinical research in the quest for complete bypass of the right heart.
