Left Heart and Biventricular Bypass

Critical Care Clinics, 1986
Various forms of circulatory assist devices are currently under investigation. Clinical use of ventricular bypass devices ranging from roller-pump-driven units to pneumatically powered VADs have been in use for several years. These devices are indicated for patients in cardiogenic shock following cardiac surgery or myocardial infarction when all other ...

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.

Left heart bypass in cardiac resuscitation

The American Journal of Cardiology, 1965
Abstract 1. 1. In the presence of ventricular fibrillation, left heart bypass increases systolic and diastolic blood pressures by 20 to 100 mm. Hg and thus augments the blood supply to anoxic tissues. 2. 2. After coronary artery ligation, bypass delays the onset of ventricular fibrillation. 3. 3.

Simple technique of left heart bypass

The Annals of Thoracic Surgery, 1996
Left heart bypass is typically established by left atrial appendage cannulation. We report a technique using inferior pulmonary vein cannulation, which is technically simpler. We have used this technique in 20 cases with reliable venous inflow.

Left Heart Bypass

2011
Simple cross-clamping of the descending thoracic aorta produces visceral ischemia, particularly at the level of the spinal cord and the kidneys, and stresses the heart due to an abrupt increase of the after-load. Several methods of distal aortic perfusion have been developed to reduce end-organ ischemia, to support the heart, and control proximal ...

Coronary bypass in left heart failure

Seminars in Thoracic and Cardiovascular Surgery, 2002
Clinical experience is accumulating that coronary artery bypass grafting is of great benefit in patients with advanced ischemic cardiomyopathy. At Yale University, we have analyzed short- and long-term results in 188 consecutive patients with an ejection fraction (EF) of 30% or less undergoing coronary artery bypass grafting by a single surgeon.

Change of Heart: The Bypass Experience.

Annals of Internal Medicine, 1986
In these times of technological advance, the unimaginable seems to have become the routine. Yet any recipient of a medical opinion or procedure (regardless of its simplicity or complexity) recognizes some common and traditional expectations for their physician.

Biventricular Bypass: Alternative to Univentricular Bypass and Total Artificial Heart–Bridge

Artificial Organs, 1991
Abstract: Left ventricular and biventricular bypasses (LVBs, BVBs) were performed in 102 experiments in sheep, goats, and donkeys. Biventricular bypass was performed in the assisted circulation mode or in the paracorporeal artificial heart bridge (PCAHB) mode when the natural heart fibrillates. During implantation of artificial ventricles instead of a

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.
