uptured aneurysm originating from the left coronary
sinus toward the left ventricle (LV) is an extremely
rare problem and the incidence was reported as 1.8% of
all ruptured sinus Valsalva aneurysms [1]. This can cause
severe aortic regurgitation, coronary insufficiency, and
paroxysmal ventricular fibrillation [2].
A 59-year-old Japanese male presented with exertional
dyspnea. Chest roentogenogram revealed bilateral pleu-
ral effusion and cardiomegaly. Two hours after his ad-
mission he required resuscitation because of sudden
cardiopulmonary arrest. A two-dimensional echocardio-
gram demonstrated severe aortic regurgitation with com-
pensated LV contractility. Initially he was treated with
intensive medical care for congestive heart failure. De-
finitive diagnosis was confirmed on left-sided catheter-
ization. The aortogram showed the “wind-sock” appear-
ance of the aneurismal sac arising from the left coronary
sinus extruding into the LV (arrow in Fig 1). The left
coronary artery was intact (arrowhead in Fig 1) and no
associated lesion, such as ventricular septal defect, was
Standard cardiopulmonary bypass was used during
repair. The aneurysm was exposed through an oblique
aortotomy. The aortic valvular ring at the left coronary
sinus had detached completely from the aortic wall. The
sac tightly adhered to the free wall of the LV and the
bottom of the sac had perforated (asterisk in Fig 2). The
left coronary cusp, valvular ring (arrowheads in Fig 2), and
free wall of the aneurysmal sac were removed together.
In order to obtain firm anchorage of a mechanical valve,
mattress sutures with Teflon pledgets at the defect of
valvular ring were directly placed on the aortoventricular
junction where aneurismal wall adhering to the endocar-
dium had turned into scar tissue. Histologic examination
showed an accumulation of inflammatory cells (not only
mononuclear cells but also neutrophiles) implying that a
possible cause of aneurysmal formation was an infective
endocarditis although any organisms could be identified
from these specimens.

    • "In our group, the incidence of SVA origin was 82.10% in the right coronary sinus, 17.51% in the non-coronary sinus, and 0.39% in left coronary sinus (Table 1). Rupture of SVA most often occurs into the right ventricle, followed by the right atrium [14,15], and rarely into the left ventricle [16,17], pulmonary artery [18], or interventricular septum. In our group, rupture into the right ventricle was 54.47%, into the right atrium 31.91%, and unrupture 13.62% (Table 1). "
    [Show abstract] [Hide abstract] ABSTRACT: We introduce a simple classification of the non-coronary sinus of Valsalva aneurysm, and suggest a different approach for the corresponding type of non-coronary sinus of Valsalva aneurysm. Between October 1996 and December 2009, 45 patients with non-coronary sinus of Valsalva aneurysm underwent surgical repair. Twenty-three were male and 22 female. The mean age was 32.80±11.77 years (range, 13-67 years). We divided them into two types, type I: rupture or protrusion into right atrium; and type II: rupture or protrusion into right atrium or right ventricle near or at the tricuspid annulus. For type I (n=32), the right atrium approach was chosen, using direct suture with patch repair. For type II (n=13), the transaortic approach with right atrium incision was chosen, with patch repair through an aortic incision and direct suture through a right atrium incision. Surgical results between types I and II were compared as regards cardiopulmonary bypass time, clamp aorta time, mechanical ventilation time, and intensive care unit time, and postoperative stay time. There was no early death after operation. There were no significant differences in cardiopulmonary bypass time, mechanical ventilation time, intensive care unit time, and postoperative stay time between two types (p>0.05). There was significant difference in clamp aorta time, with type II being longer than type I (p<0.05). Forty-three patients (93.33%) were followed up; one case of coronary artery disease using medication occurred, and there was no late death. Approach through the right atrium or right atrium with aortotomy showed the same early surgical results. Our classification of non-coronary SVA is simple and practical for clinical usage.

  • [Show abstract] [Hide abstract] ABSTRACT: Hidden Markov models (HMMs) are employed to describe digital communication channels, and their parameters are estimated in a blind fashion. General nonlinear channels can be accommodated which are not restricted to be of the Volterra type. Contrary to standard HMM parameter estimation techniques, which resort to nonlinear optimization of the likelihood function, the proposed method is based on a graph theoretic approach. We exploit the De Bruijn property of the channel's state transition graph, and develop computationally efficient blind estimation procedures involving shortest path searches. We show the identifiability of the associated graph problem and discuss convergence issues. Finally, some illustrative simulations are presented

  • [Show abstract] [Hide abstract] ABSTRACT: Macroautophagy or autophagy is an ubiquitous and conserved degradative pathway of cytosolic components, macromolecules or organelles, into the lysosome. By using biochemical and microscopic methods, which allow one to measure the rate of autophagy, the role of two regulators of Gi3 protein activity, activator of G-protein-signaling-3 (AGS3) and Galpha-interacting protein (GAIP), was studied in the control of autophagy in human colon cancer HT-29 cells. In HT-29 cells, autophagy is under the control of the Gi3 protein and, when bound to the GTP, the Galphai3 protein inhibits autophagy, whereas it stimulates autophagy when bound to the GDP. GAIP, which enhances the intrinsic GTPase-activating protein activity of the Galphai3 protein, stimulates autophagy by favoring the GDP-bound form of Galphai3. We showed that GAIP is phosphorylated on its serine 151 and that this phosphorylation is dependent on the presence of amino acids that modulate Raf-1 activity, the kinase upstream of Erk1/2. AGS3, a guanine nucleotide dissociation inhibitor, stimulates autophagy by binding Galphai3 proteins. The intracellular localization of AGS3 (Golgi apparatus and endoplasmic reticulum, two membranes known to be at the origin of autophagosomes) is consistent with its role in autophagy.
