Context: Various techniques have been proposed for suturing following prosthetic aortic valve implantation, but each has its potential side effects such as patient-prosthesis mismatch (PPM) and paravalvular leak (PVL).
Aims: In the present study, we aimed to compare the postoperative sequels of aortic valve replacement (AVR) following the use of two suturing techniques including from the inside of the aorta as the common and classic suturing techniques as compared to new approach including from the outside of the aorta.
Settings And Design: This cross-sectional study was performed on patients suffering from symptomatic severe aortic valve disease and candidates for AVR in one of three referral hospitals for cardiovascular disease patients in Shiraz from 2019-2021.
Background: Electrocardiography (ECG) is now proposed as a simple and cost-effective tool to determine the location of arrhythmias before ablation. We aimed to examine the value of the QRS onset of outflow tract PVC in V1 and V2 leads recorded in fourth, third, and second intercostal spaces to differentiate two main origins for premature ventricular contraction (PVC) including right ventricular outflow tract (RVOT) and left ventricular outflow tract (LVOT).
Methods: In this prospective cohort study, a total of 58 patients were studied, from whom a surface ECG was obtained using V1 and V2 leads in the fourth, third, and second intercostal spaces.
We report the case of a 49-year-old female patient who underwent percutaneous coronary intervention of the right coronary and posterior descending arteries complicated with guidewire-induced coronary artery perforation. We successfully managed and sealed this perforation through the embolization of balloon pieces into the target vessel. ().

The present study aimed to assess the value of ST-segment changes in aVR lead and the outcome and sequels of the first episode of acute ST-segment elevation myocardial infarction.
Methods: This prospective cohort study was conducted on patients suffering first episode of ST-segment elevation myocardial infarction and underwent percutaneous coronary intervention.
Significance of ST-Segment elevation in V4R lead in patients with anterior myocardial infarction.

Background: There is some evidence of the association between ST-segment elevation in the V4R chest lead and the likelihood of anterior wall myocardial infarction; however, the link of this phenomenon with the location and the severity of the coronary involvements in such patients remains uncertain. We aimed to investigate the ST-segment elevation in V4R leads in patients with anterior myocardial infarction and also its effect on prognosis as well as the detection and prediction of the location of arterial stenosis in coronary angiography.
Methods: Data collection was performed by reviewing the hospital recorded files of 195 patients' suspicion of acute myocardial infarction who have been referred within 2 h of the onset of cardiac symptoms.
Background: Early repolarization (ER) pattern is diagnosed when the J-point is elevated on the patient's electrocardiogram. The aim of this study was to evaluate signal-averaged electrocardiography (SAECG) in patients with ER pattern.
Methods: Subjects were divided into three groups: 1-patients with normal ECG pattern (control group); 2-patients with J-point elevation in the inferior leads; and 3-patients with J-point elevation in non-inferior leads.
