Can left ventricular function recover following Bentall procedure in a patient with concomitant noncompacted left ventricular myocardium?

We report a rare case of successful left ventricular restoration of left ventricular hypertrabeculation/noncompaction (LVHT) after Bentall procedure in a patient with severe aortic regurgitation (AR) and aortic root aneurysm. At 1-year follow-up, he remained well with echocardiography showing the improved contractility of the noncompacted left ventricle. This case report emphasize that timely surgical correction of severe AR may also lead to improvement of systolic dysfunction along with concomitant LVHT.

Post Infarction left ventricle remodeling surgical treatment, different ways to get same result

The surgical ventricular restoration is an evolution of treatment of left ventricle aneurysm. The aetioloy of left ventricle aneurysm and the dilated post AMI cardiomiopaty is the same; the difference is in the extension of scarred tissue and in the quality of remote zone. Because in this anatomical situation the geometry of left left ventricle can be deeply affected, it can very difficult to have point of reference as position of apex or papillary mussles. Using a sizer and combine different surgical thecniques allow to rebuilt a ventricle with appropriate volume and shape.

Effect of Left Ventricular Restrictive filling pattern on survival in ischemic cardiomyopathy: Implications for surgical ventricular restoration.

Background: To evaluate the effects of baseline left ventricular restrictive filling pattern (RFP; E/A>2) in ischemic cardiomyopathy (ICM) patients on prognosis. Methods: Patient data was retrospectively analyzed over a period of 4.5 years to determine the effect of Echocardiographic factors on survival and re-admission for heart failure. Results: There were 102 ICM patients who had baseline RFP. We identified two sub-groups based on geometric phenotypes of left ventricular eccentric remodeling and dilated remodeling based on the relative wall thickness (RWT >0.34 or <0.34). The patients with preserved RWT had significantly more dilated ventricles ( LVIDd and LVIDs), greater pulmonary artery systolic pressures (PASP), greater diatolic dysfunction (E/A) and less left ventricular ejection fraction (LVEF); p<0.001. The number of deaths was higher in the reduced RWT patients, as were the number of re-admissions, although the time to survival and time to re-admission was not significant. Conclusions: In this pilot study on ICM patients in advanced heart failure with baseline RFP, the presence of preserved RWT indicative of eccentric remodelling demonstrated a better clinical outcome, leading to a hypothesis that the eccentric remodelling LV phenotype might benefit with SVR.

Surgical Treatment of Ischemic Dilative Cardiomyopathy by Ventricular Restoration

Patients with symptomatic post-ischemic dilative myocardiopathy of the left ventricle require, in selected cases, an operation to reshape and reduce the volume of the left ventricular chamber, in addition to surgical myocardial revascularization and mitral valve repair, with the aim of prolonging survival, improving the quality of life and minimizing the need for re-hospitalizations related to recurrent heart failure. This procedure is called surgical ventricular restoration (SVR), and is a useful tool for the treatment of heart failure patients as an alternative to heart transplant. This article provides an overview of surgical ventricular restoration for the treatment of dilative ischemic myocardiopathy. It illustrates several surgical options, describes the operative details, and discusses the correct indications for the procedure. Finally, an interesting protocol for one-step cell therapy during SVR is proposed, as an innovative treatment for heart failure patients.

Minimally invasive left ventricular reconstruction of a postinfarction, anterior left ventricular scar (BioVentrix Revivent TC procedure)

Surgical ventricular reconstruction is a proven option for treating patients who have heart failure due to a postinfarction scar or an aneurysm of the left ventricle. The BioVentrix Revivent TC System offers a reliable alternative to the conventional, more invasive surgical ventricular restoration. The system requires no sternotomy, no heart–lung machine, and no cardioplegic arrest. In this video tutorial, we present our technique for using the Revivent TC System to reconstruct the normal left ventricular shape and volume in a patient with a postinfarction, anteroapical scar.
