Successful beating heart multiple bypass grafting to the left anterior descending and circumflex artery for a left main trunk lesion was performed in 5 patients through a left thoracotomy using the “MIDCAB doughnut” for immobilization and hemostasis. After completion of left internal thoracic artery-to-left anterior descending artery grafting, a radial artery or saphenous vein graft was anastomosed safely to the obtuse marginal branch, without hemodynamic deterioration. Extending the left anterior small thoracotomy 3 or 4 cm laterally, the obtuse marginal branch could be approached easily without rotating the beating heart. The device achieved a still and stable operative field even for circumflex grafting. An inflow of the graft to the circumflex was placed at the left axillary artery to prevent blood flow shortage to the left coronary system. Mean perioperative blood flow was 29.5 ± 7.1 mL·min−1 in the internal thoracic artery grafts and 43 ± 8 mL·min−1 in the circumflex grafts. Postoperative angiography revealed patency of all grafts. The technique may extend the surgical indications for beating heart bypass surgery without cardiopulmonary bypass.

Background:The guide extension catheter – Guidezilla (Boston Scientific, United States of America) is a useful adjunctive tool in percutaneous revascularization of complex coronary lesions, and provides an extension to the guide catheter with better coaxial alignment, support and stability.Objective: The objective of this study was to describe the usefulness and easy deliverability of stent by Guidezillain the trans-radial treatment of complex coronary lesions as our initial experience.Methods:This prospective observational study was conducted at the Department of Cardiology, Ibrahim Cardiac Hospital & Research Institute (ICHRI), Dhaka from July 2016 to September 2017. The transradial approach was used in all cases. Clinical, angiographic and procedural data of percutaneous coronary interventions performed using Guidezilla, including indications for use of Guidezilla were collected and analyzed.Results:A total of 19 procedures (in 18 patients) were evaluated. 57.89% of cases were related to left circumflex coronary artery or obtuse marginal branch. The commonest challenge for use of Guidezillawas proximal angulation (63.15%) and calcification (47.4%). Commonest type of lesion was ACC/ AHA Type C lesion (63.2%). Successful stent deployment was achieved in 16 of the 19 procedures (84.2%). Among the unsuccessful cases, there was stent damage in one case and distal dissection after deployment of a stent in other. Stent deployment was not possible in two cases, due to diffuse lesion and heavy calcification.Conclusions:Guide extension catheter is a good trans-radial back-up support for calcified, complex and tortuous coronary anatomy, which otherwise may have been considered unsuitable for PCI. The use of such support can reduce the necessity for the more expensive alternative of deploying multiple small stents in order to traverse the lesions.Bangladesh Heart Journal 2018; 33(1) : 54-60

Anomalous Coronary Arteries

Anomalous coronary arteries are rare and often incidental findings. Most variants are benign. We present the case of a 75-year-old man with exertional dyspnea in whom the left anterior descending coronary artery arose from the right sinus of Valsalva, and the left circumflex coronary artery originated from the distal right coronary artery and supplied the obtuse marginal branch. No arteries originated from the left sinus of Valsalva. The patient was prescribed optimal medical therapy for atherosclerotic stenosis in his ramus intermedius. His symptoms were stable 3 years later.

A 70-year-old man presented to our hospital with non-ST elevation myocardial infarction and severely depressed left ventricular systolic function. Coronary angiogram revealed a giant fusiform aneurysm of the proximal left anterior descending artery with significant stenoses immediately proximal and distal to it and a left circumflex chronic total occlusion. The patient was treated surgically, with ligation and bypass of the aneurysm using a radial artery graft and a vein graft to the first obtuse marginal branch.

Abstract A 45-year-old woman, without cardiovascular risk factors and affected by chronic migraine, presented to the emergency department due to the onset of a typical chest pain. After performing an electrocardiogram she was promptly transported to the Cath lab, with the diagnosis of ST segment elevation myocardial infarction (STEMI), for urgent coronarography. A spontaneous dissection of the first obtuse marginal branch was detected which was treated with two drug eluting stents implantation. A day after the procedure, during a migraine crisis, at the continuous electrocardiographic monitoring it was registered a brief episode of complete atrioventricular block, which regressed spontaneously after a few minutes. For this reason, she underwent atropine test which resulted negative for AV conductance defects. No more episodes were recorded during the hospital stay, however it was decided to implant a loop recorder (Biotronik BIOMONITOR III) before the discharge. The patient received a remote monitoring device in order to allow a closer follow-up in course of the COVID-19-related lockdown, that caused a relevant reduction in the outpatients’ services. A few months later a sinusal pause of about 9 s was recorded with the emergence of an idioventricular rhythm at 25 b.p.m. When contacted by telephone the patient reported being hospitalized because of pulmonary complications of SARS-CoV-2 infection. She referred of being bedridden, without any cardiac monitor and of being asymptomatic for syncope. Thus, she was transferred to a Cardiology Unit dedicated to patients affected by SARS-CoV-2 disease, for further diagnostic investigations. This represents a case in which the remote monitoring technology resulted fundamental in the management of patients with implantable devices, in particular during COVID-19-related lockdown. However, it is at least as much important to encourage the patient to carry the transmitter with him, even in the case of unexpected events or hospitalizations, in order to gain access to all the information store in the CIED which might be useful to the diagnosis of the underlying disease. Biotronik has developed the smallest remote transmitter in commerce (CardioMessenger Smart) which is functional to this kind of use. Moreover, it has an automatic interrogation function which can send the alerts about the arrhythmic events quicker than the other brands and so it’s more practical in situations where the patient is hospitalized in non-cardiological units.
