(1) Background: Complete atrioventricular block is a well-known complication of alcohol ablation as a septal reduction therapy, implemented in selected patients with hypertrophic obstructive cardiomyopathy (HOCM). It usually occurs during or immediately after the intervention. Rare cases of late complete atrioventricular block (CAVB) have been reported, but data are still scarce in the literature regarding this issue. (2) Case report: We report the case of a 70-year-old male patient, with mild aortic stenosis, but with a significantly degenerated valve and perivalvular tissue, and a nonspecific intraventricular conduction delay, which developed intensely symptomatic CAVB, four months after alcohol septal ablation (ASA) for HOCM, along with left ventricular pressure gradient recurrence. Both problems were resolved by implantation of a dual chamber pacemaker, with pacing optimization to a short atrioventricular interval, along with a maximal tolerated betablocker therapy. With the description of the patient’s treatment and evolution in comparison with other reports and studies, this case report highlights the fact that a close clinical, electrical and echocardiographic surveillance is warranted for this kind of patients, as late CAVB may be a life-threatening complication. Previous electrical conduction problems and degenerated aortic valve and perivalvular tissue may be predisposed for this type of complication, independent of betablocker therapy. This treatment has several other beneficial effects and thus it should not be interrupted after the procedure.

Abstract Background Complete atrioventricular block (AVB) is a life-threatening condition that usually occurs in elderly people with organic heart disease. We herein describe a rare case of complete AVB in a young man with hypertrophic obstructive cardiomyopathy (HOCM) complicated by cholecystitis and cholangitis. Both cardio-biliary reflex and alcohol septal ablation (ASA) can cause conduction block, but the latter is often irreversible. However, their simultaneous occurrence in a patient has not been reported. Case presentation A 31-year-old man presented with acute cholecystitis and cholangitis and complete AVB, which had been diagnosed at a local hospital on the third day after onset. On the fourth day, he was transferred to the emergency department of our hospital because of persistent complete AVB, although his abdominal pain had been partially relieved. An echocardiogram showed a remarkably elevated left ventricular outflow tract (LVOT) gradient (105.2 mmHg) despite the performance of ASA 9 years previously. The abdominal pain gradually disappeared, and normal sinus rhythm was completely recovered 11 days after onset. We determined that cardio-biliary reflex was the cause of the AVB because of the absence of other common causes. Finally, the patient underwent implantation of a permanent pacemaker to reduce the LVOT obstruction and avoid the risk of AVB recurrence. Conclusions Cholecystitis is a rare cause of complete AVB, which is a difficult differential diagnosis when complicated by HOCM after ASA. Clinicians should be alert to the possibility of cholecystitis in patients with abdominal pain and an unknown cause of bradycardia, complete AVB, or even sinus arrest.

Complete Atrioventricular

Inferior wall myocardial infarction occurs in approximately 50% of all myocardial infarctions. The most common conduction disorder of this disease is complete atrioventricular block. Immediate attention must be given to the myocardial infarction patients with conduction block due to the increased mortality rate in these patients. Temporary pacemaker implantation and permanent pacemaker implantation are recommended in complete atrioventricular block cases that do not improve with reperfusion. In this case report, a 64-year-old-female patient came to the emergency department of a rural General Hospital with complaints of epigastric pain, dizziness, nausea, and vomiting for 2 days before admission. She had uncontrolled hypertension without a history of diabetes mellitus, dyslipidemia, smoking, or a family history of heart disease. The electrocardiogram displayed an acute inferior wall myocardial infarction and complete atrioventricular block with escape junctional rhythm with a heart rate of 17 bpm. She was diagnosed with nonreperfused inferior wall myocardial infarction and a complete atrioventricular block. She was successfully treated with only dopamine and epinephrine as the definitive treatment because the patient refused to be referred to a tertiary hospital for percutaneous coronary intervention and pacemaker implantation due to financial reasons. Dopamine and epinephrine may be considered for complete atrioventricular block if transfer to a higher level of care is not feasible and as bridge therapy while waiting for transfer.

CONTEXT: Patients with Alport's syndrome (causing 5% of end-stage renal disease) have a higher risk of heart conduction abnormalities. OBJECTIVE: To report a case of Alport's syndrome developing complete atrioventricular block during renal transplantation. CASE REPORT: A 21-year-old man with chronic renal failure due to Alport's syndrome was submitted to a renal transplantation under epidural anesthesia and, during the intraoperative period, a complete atrioventricular block was diagnosed and promptly treated with a transcutaneous pacemaker. This extensive sympathetic block can contribute towards disturbances in the heart conduction system, particularly in patients with chronic renal disease in hemodialysis. Even in patients with a normal preoperative electrocardiogram or no conduction system disturbances, some degree of atrioventricular block, including complete atrioventricular block, can occur. In this situation, a transcutaneous pacemaker provides rapid and effective treatment in the operating room, thereby permitting the planning of a definitive treatment.
