Background: To avoid rhythm disturbance, sutures for ventricular septal defect closure have been traditionally placed 2∼5 mm or more away from the edge of the ventricular septal defect. However, the traditional suturing method appears to induce right bundle branch block and tricuspid valve regurgitation after ventricular septal defect closure more than our alternative technique, shallow suturing just at the edge of the ventricular septal defect (shallower bites at the postero-inferior margin). We aimed to verify our clinical experience of perimembranous ventricular septal defect repair.
Methods: The alternative shallow suturing method has been applied since 2003 at our institution. We retrospectively reviewed the clinical data of 556 isolated perimembranous ventricular septal defect patients who underwent surgical closure from 2000 to 2019. We investigated the postoperative occurrence of right bundle branch block or progression of tricuspid regurgitation and analysed risk factors for right bundle branch block and tricuspid regurgitation.
Results: Traditional suturing method (Group T) was used in 374 cases (66.8%), and alternative suturing method (Group A) was used in 186 cases (33.2%). The right bundle branch block occurred more frequently in Group T (39.6%) than in Group A (14.9%). In multivariable logistic regression analysis, Group T and patch material were significant risk factors for late right bundle branch block. More patients with progression of tricuspid regurgitation were found in Group T.
Conclusions: Shallow suturing just at the edge of the ventricular septal defect may reduce the rate of right bundle branch block occurrence and tricuspid regurgitation progression without other complications.

Objective: To evaluate the impact of CT planning on surgical myectomy outcomes in patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) and/or mid-cavity obstruction, by comparing these outcomes with those of conventional surgical myectomy.
Methods: This prospective cohort study included patients who underwent surgical septal myectomy for HCM with LVOT and/or mid-cavity obstruction between January 2019 and May 2024 at a single tertiary center. In the CT-planned myectomy group, an expert radiologist simulated the target myectomy site through a series of post-processing methods to plan the surgical approach, provide a surgeon's view that closely resembles the actual perspective in the operating room, and present the target myectomy volume.

Images: We present multimodality imaging of ventricular septal calcification.
Case Summary: A 38-year-old man with asymptomatic gene-positive hypertrophic cardiomyopathy was found to have extensive dystrophic calcification of the ventricular septum. We hypothesized that the extensive ventricular septal calcification would represent an area of severe myocardial fibrosis, resulting in calcification secondary to postsurgical (septal myectomy) changes.

Background: We present a multimodality imaging study of a rare case of postsurgical chronically evolved pseudoaneurysm with a possible rupture buffered by the huge thrombus.
Case Summary: A patient known for previous late presentation myocardial infarction complicated by shock and ventricular septal defect and treated with surgical repair and triple coronary artery bypass grafting, was directed to our hospital for severe mitral regurgitation. Computed tomography, cardiac magnetic resonance, and echocardiography, in a multimodality approach, revealed a huge postsurgical cardiac pseudoaneurysm, with an extensive thrombus and the native pericardium not perfectly distinguishable from pseudoaneurysm tissue or surgical patch.

Constrictive pericarditis is a condition in which inflammation of the pericardium results in the loss of pericardial elasticity, leading to restricted ventricular filling. This case reports a male in his 50s who presented with symptoms of bilateral pedal oedema and dyspnoea. Examination revealed a raised jugular venous pulse, abdominal dullness and crepitations in both lungs.

Background: During the electrode screwing process in left bundle branch pacing (LBBP), the significance of the S wave in lead V6 remains elusive. Our study analyzes the change of the S wave in lead V6 under different patterns of capture and explores its mechanisms.
Methods: This study included 243 cases with criterion of selective LBBP (SLBBP), we performed continuous pacing technique and classified the electrophysiological characteristics observed during the screwing process into four patterns: left ventricular septal pacing (LVSP), non-selective LBBP (NSLBBP) in low output and in the lower output, selective LBBP.
