Article Synopsis
- The study aimed to assess if using multiple arterial grafts in redo coronary artery bypass grafting (CABG) offers any advantages over using a single arterial graft.
- Over a 40-year period, researchers examined data from 6,559 patients who underwent isolated redo CABG, matching those who received multiarterial grafts with those who received single arterial grafts to evaluate in-hospital complications and long-term survival.
- Results indicated that multiarterial grafting was linked to lower in-hospital mortality and better long-term survival rates, especially in males with two internal thoracic artery grafts.
Techniques and Results of Multiple Arterial Bypass Grafting: Towards More "Curative" Coronary Revascularizations.

Surgical coronary bypass has evolved continually, and most analyses currently favor performing coronary grafts with autologous living arterial conduits to obtain better long-term patencies and clinical outcomes. With bilateral internal mammary artery grafts and both radial arteries, 4 excellent arterial conduits exist for creating "all-arterial" revascularization in the majority of multivessel disease patients, including those with valve disorders. Using contemporary surgical techniques, it is possible to obtain greater than 95% overall early graft patencies that translate into better late outcomes, including improved survival, freedom from myocardial infarction, fewer percutaneous coronary interventions, and redo coronary bypass procedures.

We present an unusual case of a 37-year-old male presenting with neurologic signs of right parietal lobe infarction with evidence of vertebral artery dissection and persistent carotid-vertebrobasilar anastomosis as a conduit for thromboembolism.

Methods: Ninety-six consecutive patients underwent mitral valve repair from April 2009 to December 2018. Patients were divided into two groups: functional mitral regurgitation requiring simple mitral annuloplasty (FMR, n=63) or structural degenerative mitral regurgitation requiring more complex repair (DMR, n=33).
Sinus of Valsalva aneurysm rupture is a rare condition with a great potential for morbidity and mortality if not promptly diagnosed and managed. We present an unusual non-infected sinus of Valsalva aneurysm rupture in a 47-year-old female. This case report, a likely presentation of a late congenital heart defect, highlights the need for a high index of suspicion in a patient with atypical history of congestive cardiac failure.

Methods: From June 2012 to November 2014, 11 patients underwent SDD trans-radial PCI and followed up at one-month and three months. Data was retrospectively reviewed from a prospectively entered unit-maintained cardiology database.
Background And Aim: The coronavirus disease 2019 (COVID-19) pandemic has seen the cancellation of elective cardiac surgeries worldwide. Here we report the experience of a cardiac surgery unit in a developing country in response to the COVID-19 crisis.
Methods: From 6th April to 12th June 2020, 58 patients underwent urgent or emergency cardiac surgery.
Background And Aim: Access to specialized cardiac surgery is a problem in emerging countries. Here, we reflect on the approach we used to establish a cardiac surgery unit in Trinidad and Tobago.
Methods: The program started in 1993 with monthly visits by a team from Bristol Heart Institute.
