Bulging subaortic septum in hypertrophic cardiomyopathy is a potential risk factor for systolic anterior motion after mitral valve repair. Systolic anterior motion may cause postoperative mitral regurgitation and left ventricular outflow tract obstruction despite conservative management. During "minimally invasive endoscopic" and "robotic" mitral repair procedures, systolic anterior motion is prevented with concomitant septal myectomy through the mitral valve orifice. Technically, the exposure of the bulging subaortic septum is traditionally done with detachment of the anterior mitral leaflet from its annulus, leaving a 2-mm rim of leaflet attached to the annulus. The leaflet is then sutured after myectomy. As an alternative technique in robotic surgery, the exposure of the subaortic septum is feasible without anterior leaflet incision with the use of dynamic atrial retractor in mitral repair procedures. Here, we present a patient who underwent concomitant robotic mitral valve repair with posterior chordal implantation, ring annuloplasty, and septal myectomy without anterior leaflet incision using the da Vinci surgical system.

Septal reduction therapy can be considered along the lines of hypertrophic obstructive cardiomyopathy patients who have drug-refractory symptoms. This can be applied either surgical myectomy or either...
Sinus of Valsalva aneurysm (SVA) protruding into the mitral anterior leaflet is an extremely rare clinical condition; herein, we present a case of unruptured noncoronary SVA protruding into the mitral...
Left ventricular outflow tract obstruction (LVOTO) can be caused by multiple factors. One of rare causes of LVOTO is preserved anterior mitral valve leaflet and chordal apparatus after mitral valve re...
Reducing the SAM is a key way of resolving LVOT obstruction in surgery for HOCM. We developed a new technique using a floating stitch on the anterior mitral leaflet (AML). It is applied just to the mi...
The left atrioventricular valve in atrioventricular septal defect is conventionally repaired by suturing the "cleft". This may be complicated with stretching/dehiscence of the sutured zone by naturall...
The purpose of the study is to assess the role of mitral valve apparatus in the development of outflow tract obstruction in patients with hypertrophic cardiomyopathy and to identify the be...
Objective of the study: to evaluate whether alfieri technique improves clinical and hemodynamic results compared to transaortic mitral valve secondary cord cutting in patients scheduled to...
Investigators aim to assess changes in exercise capacity and quality of life after septal myectomy in patient with hypertrophic cardiomyopathy.
The purpose of this study is to prospectively evaluate the incidence of hemodynamic compromise and to obtain long-term survival data on patients with the AMPLATZER Septal Occluder
This is a follow up investigation to our previous study entitled "On-pump intraoperative echocardiography (OPIE)" (clinicaltrials.gov NCT03094325) whereby we determined that left ventricul...
Neural nuclei situated in the septal region. They have afferent and cholinergic efferent connections with a variety of forebrain and brainstem areas including the hippocampus, the lateral hypothalamus, the tegmentum, and the amygdala. Included are the dorsal, lateral, medial, and triangular septal nuclei, septofimbrial nucleus, nucleus of diagonal band, nucleus of anterior commissure, and the nucleus of stria terminalis.
Gray matter structures of the telencephalon and limbic system in the brain, but containing widely varying definitions among authors. Included here is the cortical septal area, subcortical SEPTAL NUCLEI, and the SEPTUM PELLUCIDUM. Many authorities consider the septal region to be made up of the septal area and the septal nuclei, but excluding the septum pellucidum.

Artery formed by the bifurcation of the internal carotid artery (CAROTID ARTERY, INTERNAL). Branches of the anterior cerebral artery supply the CAUDATE NUCLEUS; INTERNAL CAPSULE; PUTAMEN; SEPTAL NUCLEI; GYRUS CINGULI; and surfaces of the FRONTAL LOBE and PARIETAL LOBE.
Incomplete transposition of the great vessels in which both the AORTA and the PULMONARY ARTERY arise from the RIGHT VENTRICLE. The only outlet of the LEFT VENTRICLE is a large ventricular septal defect (VENTRICULAR SEPTAL DEFECTS or VSD). The various subtypes are classified by the location of the septal defect, such as subaortic, subpulmonary, or noncommitted.
Bundle of MYELINATED NERVE FIBERS that connects the two CEREBRAL HEMISPHERES in the LAMINA TERMINALIS. It is located ventral to the SEPTAL NUCLEI, and caudal to the median PREOPTIC NUCLEUS.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
