case_images: (a) Emergency ECG shows sinus rhythm and complete atrioventricular block with a ventricular escape rhythm of 48 bpm. (b) ECG on the first day after the operation shows 1:1 atrioventricular conduction. p valves (black arrows).

case_images: The emergency room electrocardiogram (ECG) showed sinus rhythm with ventricular escape rhythm, ventricular escape segment rate of 48 bpm, third-degree atrioventricular block, and complete right bundle branch block (Figure 1(a)). The patient's ECG showed 1:1 atrioventricular conduction on the first day after operation (Figure 1(b)).
case_images: Parasternal long-axis view of the left ventricle: (a) the right coronary sinus was dilated and the sinus wall expanded into the left ventricular outflow tract during diastole; (b) the right coronary sinus wall was sunken in systole; (c) the right coronary sinus was dilated and blood flow signals can be seen at the bottom of the ventricular septal base and the right coronary sinus region; (d) parasternal short axis: the diastolic tumor can be seen expanding into the left ventricular outflow tract and close to the anterior mitral leaflet.. RV: right ventricle; LV: left ventricle; RA: right atrium; LA: left atrium, AML: anterior mitral leaflet; MVO: mitral valve orifice; PML: posterior mitral leaflet; IVS: interventricular septum.

case_images: The myocardium of the left ventricular apex became thinner and the motion amplitude of the middle left inferior ventricular wall and the apical segment decreased (Figure 2).
case_images: CTA view showing: (a) sagittal position of the aortic root reconstruction: bag-like structure bulge on the left side of the right coronary sinus wall, located above the bottom of the ventricular septum of approximately 10 x 9 mm in size (green arrow). (b) Section of the left ventricular outflow tract: the right coronary artery originates from the right coronary sinus (red arrow), expanding and protruding into the left ventricular outflow tract (black arrow).. PT: pulmonary trunk; RCC: the right coronary cusp; LCC: the left coronary cusp.

case_images: We also detected the formation of an interventricular septal dissection above the bottom of the interventricular septum, with a range of about 10 x 9 mm (Figure 3).
