Left ventricular pseudoaneurysm with hemoptysis.

Abstract

A 53-year-old man who had previously undergone resection of a left ventricular aneurysm was admitted because of hemoptysis. Preoperative evaluation with computed tomographic scan and cardiac catheterization demonstrated a pseudoaneurysm of the inferior ventricular wall measuring 16 cm in diameter with protrusion into the left hemithorax. The neck of the pseudoaneurysm was a defect in the ventricular wall extending from the base of the mitral valve annulus to the insertion of the posterior papillary muscle. Operative repair was performed using an albumin-coated, low-porosity Dacron patch.

The effects of simulated akinetic and dyskinetic aneurysms on left ventricular systolic function: clinical implications.

OBJECTIVE: Scant attention has been directed towards quantifying the degree of mechanical disadvantage produced by akinetic and dyskinetic aneurysms. The purpose of this study was to evaluate the mechanical disadvantages of simulated akinetic and dyskinetic aneurysms on left ventricular function. METHODS: An elaborate experimental apparatus consisting of a computer-controlled water pressure chamber in which is suspended a model rubber ventricle was developed. The system has been shown to reproduce accurately the ventricular and aortic pressures found in vivo. In this study, a procedure was designed to simulate akinetic and dyskinetic aneurysms of various sizes on ventricular function. RESULTS: The results indicated that an akinetic aneurysm produces little or no mechanical disadvantage with respect to ventricular pressure since systolic paradox is minimal. However, a dyskinetic aneurysm, irrespective of size, will usually compromise ventricular function due to paradoxical systolic expansion in the bulging aneurysmic sac. In vivo, other factors, such as blood coagulation and rhythm disturbances, may influence these results. CONCLUSIONS: An akinetic aneurysm causes little or no mechanical disadvantage while the dyskinetic aneurysm, irrespective of size. will restrict ventricular function. The experimental simulation system, notwithstanding its limitations, thus provides a unique procedure to quantify akinetic and dyskinetic aneurysms.

Left ventricular aneurysms: pathophysiologic observations and standard resection.

For the past four decades, the standard approach to the treatment of left ventricular aneurysms has been to resect the aneurysm wall and close it in a linear fashion. During the past decade, evidence has accumulated that this simple approach may not be the most efficacious in terms of either short-term ventricular function or long-term survival and quality of life. To establish the basis against which the newer techniques are to be compared, this article describe the historical evolution of procedures designed to treat ventricular aneurysms, the pathophysiolgy of aneurysms, the standard surgical technique still used by most surgeons, and the rationale for the newer surgical approaches.
