In this report, we describe a case of Tako-Tsubo cardiomyopathy (TTC)--also called 'apical ballooning' syndrome--in which transient left ventricular outflow tract (LVOT) obstruction and mitral regurgitation led to haemodynamic instability. Patients with hypotension should undergo urgent echocardiography to determine if LVOT obstruction is present. This complication has been described in 10-25% of all TTC patients. In patients with hypotension and moderate-to-severe LVOT obstruction, inotropic agents should not be used because they can worsen the degree of obstruction. Instead, it is suggested to use beta-blockers, which can improve haemodynamics by causing resolution of the obstruction. The fact that some patients do not survive their acute TTC event only underscores the importance of prompt recognition and targeted management of dynamic LVOT obstruction.

We present a first in human experience of transseptal balloon-assisted translocation of a mitral anterior leaflet (BATMAN) to facilitate transcatheter mitral valve replacement in a patient with severe mitral annular calcification who was at high risk of left ventricular outflow tract obstruction.

Background: The Valsalva maneuver is essential in evaluating left ventricular outflow tract (LVOT) obstruction in patients with hypertrophic cardiomyopathy (HCM). Traditionally, a self-directed Valsalva (SDV) maneuver is taught to patients using vague instructions such as "bear down." SDV is often not performed correctly leading to variable results and underestimation of the true provocable LVOT gradient.

Introduction: Hypertrophic cardiomyopathy (HCM) is a common genetic heart disorder. It is characterized by left ventricular hypertrophy and impaired cardiac function, with forms categorized into obstructive (oHCM) and nonobstructive (nHCM). Traditional treatments address symptoms but not the underlying disease mechanism, highlighting the need for novel therapies.

Background: A partial atrioventricular septal defect (AVSD) with a hypoplastic left ventricle and common atrium is a rare combination of cardiac anomalies that can be associated with Ellis-van Creveld (EVC) syndrome.
Case Summary: A female neonate with EVC syndrome was diagnosed with an unbalanced AVSD and hypoplastic left ventricle. Pulmonary artery banding and ductus ligation were performed at 23 days after birth.

Acute coronary occlusion during transcatheter aortic valve implantation (TAVI) is an unwarranted complication associated with high mortality. The current TAVI practices recommend a multidetector computed tomography (MDCT) evaluation of the aortic valve, the left ventricular outflow tract, and the aortic root to determine the conventional risk factors for coronary obstruction like low-lying coronary ostia and narrow sinuses of Valsalva, mandating prophylactic coronary protection or native valve leaflet modification in high-risk patients. Despite optimal anatomy, acute coronary occlusion can still occur due to multiple mechanisms, one of which is coronary embolism due to thrombus, calcium, or native aortic valve fragments.
