Left ventricular outflow tract obstruction is now recognized as a common complication of takotsubo syndrome, resulting in more serious acute and long-term outcomes. We describe a case of takotsubo syndrome where a transient sigmoid septum produced left ventricular outflow obstruction and explore the mechanisms leading to this occurring. This phenomenon has not been previously described. < Left ventricular outflow tract (LVOT) obstruction is a complication of takotsubo syndrome. A sigmoid septum is a risk factor for LVOT obstruction occurring. This case highlights that a sigmoid septum can be transient and may be secondary to surge in catecholamines and inflammatory markers.>.

Background: Defining the nature of the unilateral cleft lip and palate nasal deformity (uCLND) and its optimal surgical correction continues to be a challenge. The purpose of this study was to develop a data-driven model of the primary unrepaired osseocartilaginous skeleton of the nasomaxillary complex.
Methods: CT scans of nineteen 3-month-old infants with unrepaired unilateral cleft lip and palate and nineteen age- and race-matched controls were analyzed.

Background: Sigmoid Ventricular Septum (SVS) is a type of hypertrophic cardiomyopathy characterized by a reduced angle between the basal interventricular septum and the ascending aorta, and SVS can lead to dynamic Left Ventricular Outflow Tract obstruction (LVOTO) during hypercontractile states. Patients experiencing LVOTO may manifest symptoms such as angina, syncope, etc. Radiofrequency ablation (RFA) has been utilized to treat patients with hypertrophic obstructive cardiomyopathy, but there is no reports on its use in treating LVOTO resulting from SVS.

Background: In quantifying left ventricular (LV) diameter, which position for echocardiographic measurements, mitral valve tip level (MV-tip) or LV mid level (LV-mid), more accurately represents the LV volume is unclear. Furthermore, which factor affects the measurement error also has not been elucidated.
Methods: We enrolled 150 patients without myocardial infarction and local asynergy who underwent echocardiography and cardiac magnetic resonance imaging (CMRI).
We report a case of a 21-year-old male with stage IIIB sigmoid colon adenocarcinoma who experienced atypical chest pain post-adjuvant chemotherapy with Capecitabine (5-FU prodrug). Evaluation revealed an unexpectedly detected interventricular septum hemangioma. Due to the vasospasm effect of chemotherapy presenting with semi-ischemia, conservative management was chosen for atypical presentation.

There is ample literature associating LVOTO with hypertension, AMI, LV hypertrophy, sigmoid septum, HCM, and TTS, particularly in midde aged/elderly/postmenopausal women, suggestive of a causal role for LVOTO in the pathophysiology of TTS. Although there is significant evidence that TTS is triggered by a sudden autonomic sympathetic nervous system surge and/or elevated blood-ridden catecholamines, the exact pathophysiologic trajectory leading to the clinical expression of the disease is still being debated. This review expounds on the possibility that LVOTO is a causal early component of this trajectory, and proposes that TTS is a malady within the broad spectrum of the myocardial ischemic injury/stunned myocardium states.
