Recent advances in coronary revascularization include total arterial grafting, however, in a few cases, harvesting the right internal thoracic artery (RITA) is not possible due to various reasons. In such cases, where the aorta is also calcified, few surgeons perform Y anastomosis configuration with the left internal thoracic artery(LITA) and saphenous vein which can have disastrous complications. Our patient is a 65-year-old man who was diagnosed with multivessel coronary disease and presented with a coronary steal during coronary artery bypass grafting surgery. The RITA was not harvested due to osteoporosis sternum. LITA-saphenous vein Y anastomosis configuration was done as the aorta was calcified. The anastomosis was done between the LITA to the left anterior descending (LAD) artery and the Y arm saphenous vein was anastomosed to an obtuse marginal (OM)branch. He developed coronary steal following anastomosis of the Y graft to the OM branch. The patient had ischemic changes inside the operation theatre in LAD territory, hence grafts were revised following which the patient became stable. There is a high possibility of a coronary steal when the caliber of the Y arm does not match with the LITA. LITA-saphenous vein Y anastomosis can cause more complications as the saphenous vein is much bigger in caliber compared to the LITA.

Background: Mitral regurgitation (MR) is the most common valvular disease worldwide. MR has been managed surgically, with either a mitral valve replacement or repair. Percutaneous transcatheter mitral valve repair (TMVr) with MitraClip^® insertion has gained wide popularity and success over medical and surgical therapy for MR. Some patients with acute MR or decompensated heart failure could benefit from urgent TMVr. This meta-analysis aims to compare clinical outcomes of urgent versus elective TMVr.

Methods: We performed a study-level meta-analysis to compare the clinical outcomes of urgent versus elective TMVr using the MitraClip system. The primary endpoint outcome was all-cause mortality. Additional outcomes included procedural success, postoperative acute kidney injury (AKI), stroke, and length of in-hospital stay.

Results: Overall, 30-day mortality was significantly higher in the urgent group (odds ratio [OR]: 2.74; 95% confidence interval [CI] [2.17, 3.48]; P < 0.00001; I² =0%). However, subgroup analysis of matched cohorts showed no significant difference between both groups (OR: 1.80; 95% CI [0.94, 3.46]; P = 0.08; I² =0%). One-year mortality was similar between both groups (and: 1.67; 95% CI [0.96, 2.90]; P = 0.07; I² =0%). Procedural success was similar between both groups (89.4% vs. 89.8%; P = 0.43). Postoperative AKI was significantly higher in the urgent group (OR: 4.12; 95% CI [2.87, 5.91]; P < 0.00001; I² =0%).

Conclusion: Urgent TMVr should be indicated in select populations as it is considered therapeutic with acceptable outcomes therein.

Patients who suffer from severe tricuspid regurgitation (TR) and who are at high surgical risk have no standard care therapy. Therefore, minimally invasive and safer methods are sought. K-clip™, the first ultrasound-positioned interventional tricuspid annuloplasty instrument intended for percutaneous transcatheter repair. We report a patient with severe functional TR and high surgical risk who underwent K-clip™ tricuspid annuloplasty under echocardiography and fluoroscopy guidance.

Context: There has been a significant increase in global cardiac-related fatalities, particularly over the last five decades. In India, cardiovascular diseases have emerged as a prevalent condition. Moreover, the incidence of sudden cardiac death has shown a steady rise worldwide.

Aims: The aim of this study was to research how frequently cardiac disease was found during postmortem/autopsy cases and how it affects sudden death.

Materials and methods: The research was conducted at the Department of Pathology, SRTR, GMC, Ambajogai, India. One hundred and eighty cardiac specimens were examined from October 2019 to October 2021. Formalin-fixed heart specimens had multiple sections cut out of them at 4-5 mm intervals. The tissues underwent preparation, followed by sectioning into 4 μm thickness using paraffin. The standard staining method of hematoxylin and eosin was used to stain the samples. Different cardiac histomorphological alterations were assessed.

Results: The study included 180 autopsy cases. The highest numbers of cases were observed in the age group of 31-40 years (20.2%). Triple-vessel involvement was seen in the majority of 61.5% of cases, out of 180 cases, 52.7% of cases were of hypertrophy.

Conclusions: The research highlights the prevalence of cardiovascular diseases, particularly atherosclerosis and hypertrophy. Notably, sudden death cases showed a distinct distribution across the study years, with males being predominantly affected. This underscores the urgent need for preventive measures and interventions to prevalent cardiovascular conditions effectively.
