Transition to heart transplantation in post-myocardial infarction ventricular septal rupture: a systematic review.

Post-myocardial infarction ventricular septal rupture (MI-VSR) remains a dreadful complication with dismal prognosis. Surgical repair is the primary treatment strategy, whereas the role of heart transplantation (HT) as a primary option in MI-VSR is limited to case reports (CRs). We performed a systematic review of CRs to describe in-hospital mortality, and survival at 6 and 12 months in adult patients with MI-VSR treated with HT as a primary or bailout strategy. We performed a comprehensive search of Web of Science, PubMed, and Ovid Medline. The last search was completed on March 10, 2020. An aggregated score based on the CARE case report guideline was used to assess the quality of the CRs. We included CRs that described adult patients with MI-VSR treated with HT as a primary or bailout strategy. A total of 14 CRs between 1994 and 2015 were included, retrieving and analyzing the characteristics of 17 patients. A total of 12 patients underwent HT, with HT being the primary strategy in 8 patients and a bailout strategy for 4 patients following initial surgical repair, while 5 patients died awaiting HT under mechanical circulatory support (MCS), accounting for the total in-hospital mortality of this series (29%). Regarding long-term outcomes, 6 patients were reported to be alive at 6 months and 1 year after HT, while information was missing in the remaining 6 patients. In conclusion, HT supported by the use of temporary and durable MCS as a bridge to HT could be a feasible primary or bailout strategy to reduce the high in-hospital mortality of patients with MI-VSR.

Management of peri-device leak following left atrial appendage closure: A systematic review.

OBJECTIVE: This study aimed to examine the cumulative experience of peri-device leak (PDL) closure following left atrial appendage (LAA) closure. BACKGROUND: The management of PDL following LAA closure remains controversial. While PDL closure has been proposed, procedural features and clinical outcomes have not been well established. METHODS: A systematic review of all published cases of PDL closure with available anatomical, procedural, and clinical outcomes was performed. RESULTS: We identified 18 indexed publications and 110 cases between April 2013 and March 2020. 71 patients (mean age 72 ± 8 yrs), met study criteria and were included. PDL closure was most common in males, bilobar LAA morphology, and after Watchman procedures. The mean PDL size was 7.6 ± 5.8 mm (range 2-26 mm). Leaks were classified according to size: small (<5 mm; 45%), moderate (≥5-9 mm; 25%), and large (≥10 mm; 30%). Endovascular coils and endovascular plugs were used to close both small and moderate sized leaks, and second LAA closure devices were exclusively used for large PDLs. Successful PDL closure occurred in 90%, and was similar between PDL sizes and types of occluder used. Procedural complication rates were uncommon (2.8%). No strokes were reported following PDL closure at 6 months. CONCLUSIONS: In patients with PDL for whom discontinuation of OAC may be considered unsafe, percutaneous closure using a tailored approach with either endovascular coils, plugs, or second occluder represents a safe, and feasible alternative associated with favorable clinical outcomes.

A case of cardiac sarcoidosis with successful heart transplantation after COVID-19 infection.

Arrhythmogenic right ventricular cardiomyopathy and cardiac sarcoidosis can both present with ventricular tachycardia. We report a case of a patient whose histological diagnosis was not only confirmed by the transplanted heart but who also underwent successful transplantation after overcoming COVID-19. .

Cardioform Septal Occluder for the Closure of a Peri-Device Leak After Initial Watchman Implantation.

Left atrial appendage occlusion has become a safe and effective alternative for stroke-risk reduction among patients with non-valvular atrial fibrillation (AF). Although complete closure is ideal, residual peri-device leaks (PDL) are not uncommon and have been associated with an increased residual risk of stroke. PDL closure has been proposed as an alternate strategy to allow for the safe discontinuation of oral anticoagulation. We describe the safety and feasibility of successful PDL closure using a non-fenestrated Cardioform (Gore Medical, Flagstaff, Arizona) septal occluder after initial Watchman (Boston Scientific, Marlborough, Massachusetts) implantation.
