Coronary artery bypass surgery (CABG) in dextrocardia with situs inversus patients is comparatively rare in literature. Abnormalities in the embryonic cardiac loop and other associated congenital anomalies pose challenges in both anaesthesia and surgery. We describe, a successful elective off pump total arterial revascularization coronary artery bypass surgery with RIMA-LIMA en Y configuration with 5 distal anastomosis were performed in a 64-year-old patient with dextrocardia, situs inversus and triple vessel coronary artery disease. The peri-operative periods were uneventful. This report highlights the feasibility, benefits and relative ease of Off-pump RIMA-LIMA en Y graft in such patients
Cardiothoracic Surgery Leadership and Learning Are Indispensable To Each Other

Cardiothoracic surgery is facing a multitude of challenges in leadership and training on the global scale, these being a complex and aging patient population, shortage of cardiac surgeons, diminishing student interest and trainee enthusiasm, increasingly challenging training obstacles and work-life imbalances, suboptimal job prospects, reports of discrimination and bullying and lack of diversity as well as gap between innovation and technology, clinical application, and training of future surgeons. The survival of cardiac surgery hinges on the leadership attracting and retaining young surgeons into the specialty. Mentoring, leading through example, recognizing the work-life imbalances, adapting to diverse and modern training models and embracing diversity with respect to gender and race, will ultimately be required to create and cultivate a nurturing environment of training and preparing future leaders. The vision for training future generations of cardiothoracic surgeons must rely heavily on strengthening the unity of the heart team. In doing so we can provide the best possible care for our patients and a most fulfilling career for the future generation of cardiac surgeons.
To Repair or Replace- The Root Dilemma in Aortic Dissections

Significant dilemma exists regarding management of the aortic root pathology in acute aortic dissections. Several strategies for both repair and replacement exist and there is a lack of clarity on the superiority of one over the other. Important factors that influence management strategies include involvement of the sinuses, competence of the aortic valve, presence of Marfan's syndrome and connective tissue disorders, as well as availability of surgical expertise. The wide variability in these factors makes it unlikely for any one technique to be suitable for management of all aortic roots and the root pathology has to be tailored to an individual patient.

The incidence of stroke after coronary artery bypass grafting (CABG) is around 1.3% in the Society of Thoracic Surgeons database but carries a mortality of almost 20% (1,2). The stroke rate is even higher with aortic valve replacements with the Determining Neurologic Outcomes from Valve Operations (DeNOVO) study reporting stroke rates as high as 17% (3). It is also likely that variations in definition of stroke leads to underreporting of this event. There is thus, no denying that stroke remains the Achilles heel of cardiac surgery and efforts must be made to mitigate its occurrence.

Hybrid coronary revascularization (HCR) consists of left internal thoracic artery (LITA) graft to the left anterior descending (LAD) artery and transcatheter revascularization of the non-LAD stenosis in specific settings to achieve complete coronary revascularization. Technique to perform the LITA to LAD graft has ranged from median sternotomy with cardiopulmonary bypass to robotically assisted totally endoscopic coronary bypass surgery using beating heart revascularization.

Robotic totally endoscopic techniques to perform the LITA to LAD graft, coupled with PCI, provides the least invasive option to achieve hybrid coronary revascularization (HCR). Shorter hospital stay and reduced need for blood transfusions have been consistently being reported by several studies along with similar long-term outcomes. Considerable variations exist in the definition of HCR which can be single or two-staged with surgical revascularization being carried out after PCI or vice versa. Variations also exist with respect to usage of cardiopulmonary bypass, surgical incisions, and use of minimally invasive robotic techniques. The different strategies of HCR do not lead to similar outcomes and the findings of one strategy cannot be extrapolated to the entire group. Studies reporting different strategies of HCR, should ideally provide more granular data when reporting outcomes.
Mitral Valve - Innocent Bystander or Master of its Own Destiny?

It has been long believed that ischemic mitral regurgitation is secondary to left ventricular remodelling and the mitral per se remains unaffected. This proviso has recently been challenged and the mitral valve has been described as a structure that responds and adapts to challenges and attempts to correct the mitral regurgitation. The response of mitral valves in this setting can be incomplete or can even be mal-adapted. The ability of the mitral valve to respond in this manner has been described as “mitral plasticity”. Endothelial to Mesenchymal transition and Valvular Interstitial Cells are key to this mitral plasticity and function through a complex array of signalling pathways. Identification and manipulation of these pathways may provide a possibility to correct the incomplete or mal-adapted mitral valve responses. Surgical treatment can also be tailored based on whether the valve has maladapted or has undergone incomplete adaptation.

The authors in this manuscript have reported an increase in the number of vascular emergencies seen during the early phase of the COVID-19 pandemic in the Lombardy region of Italy. A significant increase in the number of acute limb ischaemia was seen during this phase along with other vascular emergencies. In this review, we have tried to examine this association between increase in vascular emergencies and COVID-19 infection. We have also described the differences in presentations, prognosis and procedural outcomes following operative interventions in these patients compared to the non-COVID patients. An attempt has been made to assess the role of adjunctive measures like intravenous heparin to improve outcomes.

While there is significant awareness regarding droplet and contact transmission, aerosols are generally underestimated as a potential mode of transmission of SARS-Cov-2 infection. With the gradual resumption of cardiac surgical activities, the cardiac surgical operating room will become an important potential source of infection to the cardiac surgeon and other healthcare workers participating in the operation. There is also diminished awareness about the different aerosol generating procedures (AGP) in the cardiac surgical operating room. In this mini-review we intend to highlight the various aerosol generating procedures that are common in cardiac surgery. This will help increase the awareness among surgeons to AGP. A practical approach to taking preventive measures have also been discussed.
