Complete bypass of the right heart

American Heart Journal, 1963
Abstract The right ventricle is generally considered to be an organ that is indispensible to the circulation and essential in maintaining normal venous pressure and adequate pulmonary blood flow. This concept has been recently challenged by several investigators.

Performance characteristics of the right heart bypass preparation

American Journal of Physiology-Legacy Content, 1960
In eight dogs under morphine-barbital anesthesia, the right ventricle was replaced by a sigmamotor pump in order to study steady-state responses of circuit pressures to arbitrary variations in ‘right heart’ output. In the systemic circuit, it was found that arterial pressure (PAS, mm Hg) was a positive and venous pressure (PVS, mm Hg) a negative ...

Right heart bypass for left circumflex coronary artery bypass grafting

Heart and Vessels, 2000
Displacement of the heart to expose the left circumflex artery (LCX) causes hemodynamic disturbance during off-pump coronary artery bypass grafting (CABG). We applied right heart bypass (RHB) using a heparin-coated centrifugal pump without an oxygenator in an attempt to stabilize the hemodynamics. Five mongrel dogs (15.5-20 kg) were used.

Beating coronary bypass with right-heart bypass

The Japanese Journal of Thoracic and Cardiovascular Surgery, 2002
Two patients with bilateral obstructive carotid artery disease underwent beating heart coronary bypass including revascularization of the circumflex branch using right-heart bypass in a stable hemodynamic state. Without this mechanical support, lifting the left ventricle for the exposure of the posterior wall could impair the hemodynamic state of the ...

A Tribute to the Pioneers of Right Heart Bypass: An Historical Review

World Journal for Pediatric and Congenital Heart Surgery, 2020
Cavopulmonary anastomosis was first described by Carlon, Mondini, De Marchi in a canine model in 1951 and later, in the clinical practice, by Glenn in 1958. Total right heart bypass was first introduced by Fontan and Kreutzer in 1971, in each instance as treatment for tricuspid atresia.

Hemodynamics of different degrees of right heart bypass: experimental assessment

The Annals of Thoracic Surgery, 1995
Although their assessment could be of the utmost importance to determine the surgical treatment for patients with univentricular hearts, differences in ventricular performance between partial and complete right heart bypass remain to be defined.Three different degrees of right heart bypass were investigated in 5 mongrel dogs: (1) superior vena cava to ...

Total Extracardiac Right Heart Bypass Using a Polytetrafluoroethylene Graft

Journal of Cardiac Surgery, 1997
With regard to hemodynamics and late arrhythmias, total cavopulmonary connection has been accepted as a superior technique as compared to Fontan type procedures. However, intra-atrial baffles for lateral tunnel or conduit remain construction retain some similar disadvantages.As an alternative to total cavopulmonary connection, total extracardiac right ...

Right heart circulatory support facilitates coronary artery bypass without cardiopulmonary bypass

The Annals of Thoracic Surgery, 2000
Revascularization of the posterior wall often causes hemodynamic instability in beating heart coronary artery bypass (CAB). Our previous clinical studies have shown that tilting the heart primarily alters right-heart hemodynamics. The purpose of this study was to evaluate right-heart support in clinical cases.Seventeen patients underwent beating heart ...

Post Right Heart Bypass Operation

2017
The evolutional invention in congenital heart surgery, Fontan procedure, provided the patients with single ventricle or physiological single ventricular patients to live without cyanosis. Decades after Fontan-type procedure, there are various and serious problems, which should be solved.

New technique of right heart bypass in congenital heart surgery with autologous lung as oxygenator

The Annals of Thoracic Surgery, 2004
Modifications have been made in cardiopulmonary circuit to reduce the inflammatory deleterious effects and cost. We present our experience of one such right heart bypass (RHB) circuit utilizing autologus lung as oxygenator.From September 2001 to December 2002, 15 patients underwent congenital heart surgery with this technique.
