Plaintiff, as executor of the estate of his mother (decedent), appeals from an order in this medical malpractice action denying his motion pursuant to CPLR 4404 (a) seeking to set aside the jury verdict as inconsistent and against the weight of the evidence. Decedent died after the right ventricle of her heart was lacerated during a pericardial window procedure (hereafter, surgery) performed by Zhandong Zhou, M.D. (defendant). The jury determined that defendant was negligent but that his negligence was not a substantial factor in causing decedent’s death. We note at the outset that the order was subsumed in the final judgment, from which no appeal was taken. In the exercise of our discretion, however, we treat the notice of appeal as valid and deem the appeal as taken from the judgment (see Cowley v Kahn, 298 AD2d 917 [2002]; Hughes v Nussbaumer, Clarke & Velzy, 140 AD2d 988 [1988]; see also CPLR 5520 [c]).
Turning to the merits, we conclude that Supreme Court erred in denying plaintiffs motion. According to plaintiff, defendant was negligent in performing the surgery inasmuch as he “tore the decedent’s right ventricle!,] leading to massive bleeding, cardiac arrest and anoxic brain damage.” Plaintiff presented expert testimony to support that allegation, and defendant countered with contrary expert testimony. In finding that defendant was negligent, the jury presumably credited the testimony of plaintiffs expert on that issue and, here, “the issues of negligence and proximate cause were so inextricably interwoven as to make it logically impossible to find negligence without also finding proximate cause” (Rubin v Pecoraro, 141 AD2d 525, 527 [1988]). We therefore conclude that the verdict could not have been reached upon any fair interpretation of the evidence because defendant’s negligence necessarily contributed to the death of decedent (see Ahr v Karolewski, 32 AD3d 805, *948806-807 [2006]; see also Brenon v Tops Mkts. [appeal No. 2], 289 AD2d 1034 [2001], Iv denied 98 NY2d 605 [2002]). Although one of plaintiffs expert witnesses testified concerning several distinct acts performed or omitted by defendant during the surgery, plaintiff established a single instance of malpractice, i.e., the negligent performance of the surgery, during which defendant punctured decedent’s heart and thereby caused her death. Thus, “[t]he jury’s finding that the defendant . . . departed from accepted medical practice in performing surgery on [decedent], but that the departure was not a proximate cause of [decedent’s death], was against the weight of the evidence since the issues are so inextricably interwoven as to make it logically impossible to find a departure without also finding proximate cause” (Lader v Sherman, 58 AD3d 809, 809 [2009]; see Calderon v Irani, 296 AD2d 778, 778-779 [2002]).
