Abstract

Parachute® implantation (PI) is an attractive treatment option for patients with left ventricular apical aneurysms (LVAA). So far, only the retrograde approach has been approved for PI. Unfortunately, severe functional mitral regurgitation (MR) restricts PI. Thus, we were intrigued to combine PI and MitraClip therapy (MCT) as a new transvenous hybrid concept. PI was performed via a transseptally placed MitraClip guide in six consecutive patients (age 73.8±5.2; 66% male). Immediately after PI, MR was treated by MCT. Invasive right and left heart haemodynamics were taken before and after PI and MCT, respectively. Procedural success was 100%. PI induced a numerical increase in cardiac output (CO: +36.4; p=0.15) and stroke volume (SV: +30.1%; p=0.09), despite some evidence of MR aggravation. Subsequent MCT successfully reduced MR at least to mild in five patients and to moderate in one patient. SV and CO demonstrated a further increase (SV: +44.3%, p=0.03; CO: +44.5%; p=0.03). The study documents for the first time the feasibility of transseptal and transmitral PI. Nevertheless, pre-procedural MR seems to counteract the beneficial effects of PI. Hence, the combined transseptal approach of PI and MCT seems to be the appropriate stra...Continue Reading

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
